Welcome to Global Perspectives #3 2025

HAEi’s CEO and Chairman of the Board, Anthony J. Castaldo, and HAEi’s President, Henrik Balle Boysen
Dear HAEi Friends,
A very warm welcome to the third 2025 edition of Global Perspectives – HAEi’s flagship magazine – where all of what is happening in the global hereditary angioedema (HAE) community comes together in one place.
At the heart of this edition is an overview of the recent 2025 HAEi Regional Conference EMEA. Over 2 days, 700 people with HAE, caregivers, and expert physicians, representing 66 Member Organizations and around 13,000 patients, heard the latest news, views, and science of HAE in a sun-drenched Rome, Italy. Under the shared theme “Embracing Opportunities” (also featured in the conference held in Asia Pacific and will be featured in the Americas next year), the conference showcased our community’s firm commitment to stronger advocacy, deeper collaboration, and improved access to diagnosis and treatment.
Young people, who are the future of HAE advocacy, are a vital part of that commitment. A dedicated family area in the main conference room was a visible reminder that families and young advocates are at the heart of our thinking, now and in the future. We were delighted to announce on stage that the highly successful HAEi LEAP program would be run again in 2026. HAEi has received many exciting proposals from the advocates of tomorrow, who are seeking learning opportunities and experiences to enhance skills that can be applied to improve the lives of people in their local HAE community. Look out for further announcements soon.
Whether you are young or old, have HAE, are a caregiver, or are a scientist, we encourage you to explore the detailed coverage of the conference. There is so much we can learn from the hard work and dedication of our HAEi Member Organizations, who turn everyday challenges into opportunities that lead to the ultimate prize — access to life-saving medicines.
Our HAEi conferences may be over for this year, but with the dawn of a new year around the corner, hae day :-) 2026 is already taking shape. This hugely popular annual celebration of the HAE community takes place every 16 May. To support your planning, this edition of Global Perspectives provides an update on all that’s happening and how to get involved.
This magazine will be the last for 2025. The publication schedule has been slightly rescheduled to better align with the timing of the 2025 HAEi Regional Conference EMEA, as well as the two forthcoming conferences – the 2026 Global Angioedema Leadership Conference and the 2026 HAEi Regional Conference Americas. The first edition for 2026 will arrive at the start of February, at the perfect time to review 2025 and preview 2026.
On behalf of the Board of Directors and the entire Executive Team, thank you for all that you do for the global HAE community. We wish you an enjoyable read, a wonderful holiday season, and a peaceful New Year.
Warmest regards,
Anthony J. Castaldo

Core activity updates from the Team
HAEi Principles for Good Governance
HAEi has recently launched the HAEi Principles for Good Governance—a set of clear, supportive guidelines designed to help our Member Organizations (MOs) grow, lead, and serve their communities with transparency and trust. Our Regional Advocacy Team members have been sharing these with the MOs in their regions. You can read principles on haei.org.
2025 HAEi Regional Conference EMEA
For our Regional Advocacy team members working with countries in Europe, the Middle East, and Africa, the 2025 HAEi Regional Conference EMEA has been a priority. Michal Rutkowski, Patricia Karani, Natasa Angjeleska, Maria Ferron, Fanny Schappler, Jørn Schultz-Boysen, and Fiona Wardman have supported their MOs to ensure strong representation at our second conference for the EMEA region. In the lead-up to the conference, these team members have also prepared presentations, prepared to be on stage, and supported those from their countries who were joining panels or sharing personal stories. You can read our special feature on the 2025 HAEi Regional Conference EMEA.
Keep reading for the non-conference-related activities from our Regional Advocacy team in their updates.
Monthly Resource Focus
A new initiative for our Regional Advocacy Team is the “Monthly Resource Focus,” where we provide a written, in-depth exploration of one of our HAEi Resources and encourage MOs to integrate these resources more fully into their organization to support advocacy, patients, and caregivers.

From Regional Patient Advocate Javier Santana
The past months have been busy with a variety of different activities to support the Member Organizations (MOs) in my region. First, I start with a historic milestone for Panama. The Government officially announced the country’s new HAE treatment guidelines, marking a crucial step toward equitable access to effective therapies. As HAEi’s RPA for Panama, I was honored to support the patient organization and doctors through meetings, ministry visits, and more over many years, culminating in this launch. You can read more about this in the Panama country update in the ‘News from MOs‘ section of the magazine.
In Costa Rica, the patient group has a new board, and I’ve been able to advise on fundraising activities, the official registration of their association in the country, and efforts to identify and engage new members. We worked together to prepare the group for a specific meeting with the National Organization for Rare Diseases (and other patient groups), where discussions centered on the newly approved rare disease law and the necessary steps for its effective implementation.
Supporting MOs with meetings and building networks is a key part of the RPA role:
- In the Dominican Republic, I co-ordinated a virtual meeting with a new physician, which resulted in commitments to collaborate with the patient group to support HAE advocacy efforts, connect the group with specialists in allergy and immunology to discuss HAE, and initiate the process for introducing treatments into the country.
- In Guatemala, Dr. Emilia Morales (an HAE patient) connected me with newly diagnosed patients. We held a meeting where I gave an orientation on HAEi’s work and provided Spanish-language materials, including HAEi’s guide ‘Understanding HAE.’
- And in Trinidad & Tobago, I’ve connected with new patients and the new doctor to develop a work plan to raise awareness of HAE and identify treatment alternatives for patients. They’ve also launched their HAEi-hosted website – check it out here.
Finally, across my Central America and Caribbean region, I’ve been promoting HAEi LEAP 2026 and the 2026 Global Angioedema Leadership Conference, and hope to encourage participation from our countries. And the Spanish-language digital books—‘Women with HAE,’ ‘Understanding HAE,’ and children’s books from The Brady Club — were distributed to promote education and awareness among patients and families throughout Latin America and the Caribbean.

News from Central Eastern Europe and Middle East
From Regional Patient Advocate Michal Rutkowski
Dear HAEi Friends,
The months of July, August, and September were exceptionally active, with a strong focus on preparations for the 2025 HAEi Regional Conference EMEA. Nevertheless, there were also non-conference-related activities that I would like to share with you.
Throughout this quarter, I maintained close contact with the majority of the Member Organizations (MOs) under my responsibility. Expanding and promoting the use of HAEi Tools and Resources remained a top priority.
I held virtual meetings with MOs from the Middle East: HAE Iran, HAE Lebanon, HAE Qatar, HAE Oman, HAE Saudi Arabia, HAE UAE, and from Central and Eastern Europe: HAE Armenia, HAE Georgia, HAE Hungary, HAE Kazakhstan, HAE Latvia, HAE Russia, and HAE Ukraine. These one-to-one communications and follow-up calls served as an essential platform for exchanging updates, addressing local advocacy priorities, and offering practical support to implementing HAEi resources. They also provided insight into each country’s progress and highlighted areas for further collaboration.
Resource development advanced during these months, in part supported by the Monthly Resource Focus. The ‘Understanding HAE’ guide was finalized in Georgian. Another HAEi booklet, ‘Women with HAE’, was completed in Russian, with versions in Georgian and Persian underway. In addition, the children’s book ‘The Rare Boy on a Race’ was translated into Czech, expanding HAEi’s resources for young patients and their families. With HAE Oman, we have initiated the website development process. In Poland, I have been actively involved in preparations for a patient conference, which will further strengthen the patient community in my home country.
HAEi’s Principles for Good Governance document was distributed and discussed with MOs, encouraging organizations to align their operations with HAEi’s best practices in leadership and transparency. As we look forward to 2026, I have conducted a round of communication with my MOs to inquire about their readiness to participate in the 2026 Global Angioedema Leadership Conference in Madrid, scheduled for 26-29 March next year. I have also initiated discussions with specific MOs regarding educational events for 2026. More details will follow soon.
The past three months have shown how collective action, resource sharing, and open communication can transform the MOs and patient experience. Every new translation, every tool implemented, and every conversation held represents another step toward ensuring that people living with HAE in Central Eastern Europe and the Middle East have access to the knowledge, support, and care they deserve.

News from East Asia
From Regional Patient Advocate Yong Hao Lim
In my region, there is a spectrum of organizations, ranging from those that have emerged more recently and are led by one or two dedicated individuals finding their voice to those that are more established. My role working with a more established organization is mainly supportive. I look for ways HAEi resources can be coordinated to strengthen their efforts and build collaborations across borders. One way of doing this is to enable knowledge to travel more freely. We are streamlining the translation of key HAEi materials, starting with Understanding HAE, so that patients and caregivers in the region can access reliable information in Simplified Chinese, Bahasa Indonesia, and Japanese.
In recent months, my focus has been on those countries with younger Member Organizations (MOs) and working with them to build the foundations for HAE awareness and support, particularly in Malaysia, Indonesia, Singapore, and Mongolia. These efforts were closely aligned with the APAAACI 2025 Congress held in Jakarta in October. I have attended the congress regularly over the past three years as it provides a valuable platform to stay connected with HAE knowledgeable physicians, introduce HAE to new clinicians, and stay updated on developments in HAE research across the region. It is also one of the few occasions where established partners and new collaborators can meet in person.
In the weeks leading up to the Congress, I connected with physicians from several countries to identify advocacy issues specific to that country that could be discussed further in person. In Indonesia, the focus is on identifying more patients and working with interested doctors. In Malaysia, the aim is to energize patient engagement and link education with professional meetings. For Mongolia, the goal is to understand the diagnostic gaps and identify senior physicians who can champion rare-disease care.
With a clear agenda in place, the in-person discussions proved especially fruitful. Physicians, including those who have been supporting HAE and HAEi work, exchanged valuable insights on how partnerships involving patient groups and physicians can anchor each stage of patient group growth. I was heartened by the renewed collaboration in Indonesia, where physicians and patient leaders are now planning concrete steps to improve access and care. Similar alignment is emerging in Malaysia and Mongolia, where doctors are exploring ways to build sustainable support systems.
Organizational growth lies in both visible achievements, such as numbers and events, and in the quieter, yet crucial, strengthening of networks and trust. Progress depends on people who are willing to learn, share, and connect. HAEi’s vision is a united and strong HAE global community. As an RPA, I am committed to supporting that process by linking efforts, aligning strengths, and helping every MO find its own rhythm of growth within our wider HAE community.

From Regional Patient Advocate Maria Ferron
I am delighted to share some of the latest achievements from across my region, showcasing how our collective efforts continue to make a real difference for people living with HAE and their families worldwide.
In September, I had the honor of attending the AEDAF (HAE Spain) II Regional Workshop for the Autonomous Region of Castilla y León, held in Valladolid, Spain. During this event, participants heard valuable advice and insights from Fabio, a young community member who joined the HAEi LEAP class of 2025, and I presented HAEi’s tools and resources.

A key part of my RPA role is supporting the translation and availability of resources into local languages. I’m thrilled to share that the ‘Women with HAE’ and ‘Understanding HAE’ booklets are now available in French, thanks to the dedication of the Moroccan association and the support of Prof Laurence Bouillet from France. In addition, ‘The Rare Boy and the Talkative Little Balloon’ and ‘HAPPINESS: Discussion Between the Rare Boy and the Talkative Little Balloon’, two wonderful children’s books created by Natasa Angjeleska (HAEi RPA for South Eastern Europe), have been translated into Spanish by members of AEDAF. These will be available on the HAEi Youngsters website: youngsters.haei.org. These milestones will help even more people with HAE and their caregivers access essential information in their native language.
HAE Ireland is exploring potential legal frameworks to register as an official association—and I’m delighted to support them with this vital step toward strengthening their advocacy and visibility.
HAEi’s Principles for Good Governance have been shared with all MOs in our region.
Another exciting update: HAEi LEAP is returning in 2026! I have been sharing this announcement across the region to inspire and recruit the next generation of young leaders, who, with the support of their MOs, are eager to become our future advocates.
Finally, I would like to express my heartfelt thanks to all participants from our region who contributed to the 2025 HAEi Regional Conference EMEA. Your active involvement and collaboration made the event a truly positive and memorable experience. Together, we continue to build a stronger, more connected HAE community—one that uplifts, empowers, and supports every member across the region.

News from South America and Mexico
From Regional Patient Advocate Fernanda De Oliveira Martins
HAEi Member Organizations (MOs) do an incredible job raising awareness about HAE, providing essential support to patients, and collaborating with doctors and representatives from pharmaceutical companies. HAEi offers a range of tools and services to support MOs in what can- at times- be demanding work. In my region — South America and Mexico — we held the first Member Organization Growth and Impact Summit (MOGIS) at the end of May. At this Summit, MO leaders received guidance and support to develop 12-month action plans. My focus over the past few months has been to follow up with MOs on their plans and to offer assistance and advice as needed. HAEi has also worked to simplify and improve the efficiency of this process. MOs now have their plans available in Focal Point and can update them online. By integrating the plans into Focal Point, MOs can more easily track their activities and integrate the relevant HAEi tools to support their delivery.
Over the last two months, I’ve shared the Monthly Resource Focus with my region MOs, as well as information about HAEi events and ACARE events. MOs are always welcome to contact me for support, and I will help however I can. One recent example is assisting an MO in getting set up and starting to use HAEi Connect.
In my region, MOs also benefit from the Brady Club resources published by our neighbor, HAEA, in both English and Spanish. We reproduce the book in our region’s countries, and children from my region’s countries have been sending their stories for publication in the magazine.
You can find Brady Club resources on the HAEi Youngsters’ Community website. Explore the site to find all our other resources for kids and youngsters!

From Regional Patient Advocate Fanny Schappler
These past few months have been rich in progress for South Asian countries. I’ve been supporting the continued translation of HAEi resources into local languages, and one result is several new Emergency Cards available on haei.org. HAE Bangladesh and HAE India launched new websites in August and September, respectively, including a list of knowledgeable doctors and, most importantly for India, a description of how to get treatment access under the National Plan for Rare Diseases.
A key aspect of the RPA role is supporting Member Organizations (MOs) through facilitation. In this way, I’ve supported HAE India board meetings and in conversations with one of the pharmaceutical manufacturers, with a view to collaborating on shared interests, such as increasing diagnostic rates across the country. In Pakistan, I facilitated their first educational HAE webinar. Featuring Dr Farrukh Sheikh, Dr Muhammad Hussain, Moazzam Farooq (MO Lead), and guest international speaker Prof Philip Li, HAE Pakistan reached around 50 doctors across the country.
Lastly, HAEi is in discussion with a Sri Lankan lead immunologist on an exciting project involving the newly created Institute of Allergology and Immunology in Colombo. We hope the project will come to fruition in January, and I look forward to bringing you more news on this in a future issue of the magazine.
Outside of the 2025 HAEi Regional Conference EMEA, to support the DACH countries I’m responsible for, I’ve taken the lead in translating HAEi’s ‘Women with HAE’ guide into German. We published the guide in German on haei.org in early September.
Thanks to the invaluable support of MO leaders & local doctors, we’re making strides in diagnosing more patients, and getting them & their families the local support they deserve.

News from South Eastern Europe
From Regional Patient Advocate Natasa Angjeleska
Although my work in the South Eastern Europe (SEE) region over the past three months was mainly focused on the 2025 HAEi Regional Conference EMEA, I also had the opportunity to provide support in sharing information with physicians about the possibilities of participating in a couple of webinars through the ACARE network. The level-up webinars offer the opportunity to gain up-to-date knowledge about various treatment options for HAE, as well as updates from ongoing clinical studies.
The newly announced HAEi LEAP 2026 program is an exciting opportunity for youngsters (and their Member Organizations). I’ve shared the call for applications with the countries in my region. This is another possibility to support future HAE advocates who can bring new, fresh ideas and initiatives to MOs. I truly hope to have participants from SEE in the class of 2026.
Another focus in this period was expanding the languages in which the ‘Understanding HAE’ guide is available. We already have versions for 7 languages spoken in the SEE countries, and are working on translations in Macedonian and Bulgarian. These booklets are expected to be available soon in both web and printed versions. The translation of ‘Women with HAE’ into Bulgarian is also finalized and ready to be added to the already available 4 languages spoken in SEE countries. These booklets are recognized as excellent resources providing collated information for HAE. They are easy to understand for the public, decision-makers, and stakeholders who come into contact with HAE patients for the first time. The guides support these readers with basic information as a starting point to understand this rare disease.
I am happy that the third picture book for ‘The Rare Boy on the race: I swell, but you cannot tell’ was translated into the Czech language. We hope it will provide more options for reading and educating younger generations about the opportunities available to HAE patients, enabling them to enjoy life despite the disease, and instill compassion, kindness, and inclusivity among the younger generation.
There was an opportunity to meet with the new Regional Medical Advisory Panel (RMAP) member for Montenegro, Dr Nikola Delevic. Also at the meeting were Dr Lidija Pocek and patient lead Marija Kalugjerovic, and we discussed future steps to improve treatment options for patients in Montenegro and explored different ways for collaboration in the SEE region and beyond.

News from Sub Sahara Africa
From Regional Patient Advocate Patricia Karani
Collaboration with doctors across the region remains a cornerstone of my work. In the region, there is a network of HAE physicians, including Dr Sangassanga from Mozambique, Dr Innocent Kashongwe from DR Congo, Dr Ntyo’o Arnaund from Cameroon, Dr Suad Kamara from Sierra Leone, and Dr Pap Samba Agne from Senegal. I have encouraged them to engage with other specialists to motivate them to take an interest in managing HAE cases — both in countries with established MOs and in those where HAE patient advocacy groups are emerging.
The physician network addresses cases of unexplained angioedema that do not respond to allergy treatments and works toward accurate diagnoses. Encouragingly, I’ve worked with several physicians to include HAE as a topic in their talks when they speak at national meetings. I’ve recently supported Dr Hamidou Tahirou from Niger and Dr Innocent Kashongwe from DR Congo with requests.
Because HAE can affect patients with other conditions such as diabetes or cancer, I’ve reached out to doctors from various medical specialties. These collaborations aim to help physicians understand how to safely manage HAE in patients receiving other treatments — an important step given the potential for drug interactions and the general lack of HAE awareness in the medical community.
Several doctors from our network attended the 2025 HAEi Regional Conference EMEA, where they gained new insights, interacted with HAE patients and caregivers, and shared experiences with other healthcare professionals and pharmaceutical partners. The response has been overwhelmingly positive, with many doctors expressing a renewed commitment to improving care for their HAE patients.
One of our most impactful ongoing initiatives is helping suspected HAE patients connect with the right specialists. In countries without HAE experts, we facilitate referrals to ACARE Centres in South Africa (Prof Jonny Peter) and Kenya (Dr Priya Bowry) for accurate diagnosis and subsequent management in their home countries. This effort not only benefits patients but also enhances local doctors’ understanding of HAE, contributing to stronger regional expertise and ultimately improving patient outcomes.

Welcome to the 2025 HAEi Regional Conference EMEA
Tony Castaldo, HAEi CEO and Chairman of the Board, and Henrik Balle Boysen, HAEi President, took to the stage to welcome all participants to the 2025 HAEi Regional Conference EMEA. In front of around 700 patients from more than 60 countries, caregivers, healthcare professionals, and industry supporters, Federica Braghieri and Alice Ferrari from the Italian HAE organization, A.A.E.E APS-ETS, joined Tony and Henrik on stage.
Speaking in her native language, Federica told the audience that the Italian organization was founded in 1980 by a group of 30 patients, along with Professors Angelo Agostoni and Marco Cicardi. Now, 45 years later, there are 26 specialist centers for the treatment of HAE in Italy, and approximately 1200 diagnosed patients.
‘Without knowledge, there can be no diagnosis. Without diagnosis, there can be no treatment.’
– Federica Braghieri, HAE ItalyFederica spoke about the initiatives and collaborations of the Italian organization and how they focus on patients’ well-being. She spoke of her hope for the future and thanked all who worked to improve the lives of people with HAE. She closed by welcoming everyone to Rome and wishing them a productive meeting.
Alice also welcomed participants to Rome and asked that they make themselves feel at home and part of a big family. It was Alice’s first time speaking in public, and her desire to speak on behalf of the young people living with HAE, like herself, overcame her nerves. She told the audience that being young with HAE means carrying special baggage, but it also encourages resilience, courage, and empathy. She closed her speech with words of encouragement to all: ‘I firmly believe we must look to the future positively and be the change we want to see in our own lives.”

Tony and Henrik thanked the two Italians for their welcome. They recounted the role that Italian HAE doctors and patients have played in HAE advocacy, from being among the very first national patient groups to the pivotal role of the late, great Marco Cicardi in supporting the establishment of HAEi.
The two HAEi leaders extended their own welcome, highlighting the conference’s aims and the complete alignment with the organization’s goal of gaining access to and reimbursement for life-saving and life-giving medicines. They reminded the audience how personally invested the leaders of HAEi are, as fellow patients and caregivers.
Turning to the conference agenda, both speakers highlighted the young people present in the audience and emphasized their importance for the future of advocacy. They announced that the HAEi LEAP program will take place in 2026 and that applications are now open on a dedicated website. LEAP, they explained, is an educational program for young people developed by HAEi that equips future advocates with life skills and experience in working to improve their own lives and those of others with HAE.
The scale of HAEi’s EMEA region was in the spotlight; 66 Member Organizations (MOs) and 1.5 billion people living in HAEi’s member countries across Europe, the Middle East, and Africa. Using prevalence estimates, Tony indicated that approximately 50,000 people in the region’s MO countries are likely living with HAE; yet, only 25% of these individuals (about 12,800) are currently known. It shows just how much work remains to be done.
But why is diagnosis still so low? To answer this question, Tony presented some new data on the situation across HAEi’s EMEA region. Only a few countries rated the HAE knowledge of general physicians as good or very good, and a bewildering 15 different medical specialties managed HAE across the region. This lack of knowledge and disjointed care could be hindering diagnosis.
Tony moved on to more positive news: three-quarters of MOs rated the knowledge of HAE specialists as good or very good. This forms a solid platform for improvements, said Tony. In future iterations of HAE management guidelines, there is a drive for all HAE treating physicians to consult or work with an HAE expert to ensure that everyone receives the care they need.
Moving on to treatment, Tony reminded the audience how hard the entire community has fought to create an environment that fosters research and, as a result, a variety of approved modern treatments. It is all the more remarkable, he said, when 97% of the 7000 rare diseases have no treatment at all.
An approved treatment doesn’t mean an available treatment, of course. There are countries across the region with no access to any form of HAE medication, including the non-specific therapies such as steroids and tranexamic acid.
Medicine is, of course, a potential life-saver in HAE. It is also an essential part of living a normal life with HAE, according to the MOs in the EMEA region. Almost all MOs said there was a very low likelihood of living a normal life without access to modern HAE therapies, and indeed, the absence of medication results in little chance of fulfilling life’s potential. So, the importance is well understood, Tony said.
‘The burning advocacy task that brings us all together is working towards the day when everyone with HAE has access to a modern therapy.’
We can, and we are making progress. In a 2011 survey of MOs, 45% of responding European countries had access to long-term prophylaxis and on-demand treatments. Fast forward to this year, and that number has increased to 95% of European countries with access to modern, targeted medicines for treating and preventing HAE attacks.
Tony acknowledged the very different treatment landscape outside of Europe, again drawing on MO data:
- In the Middle East and North Africa, 11 countries report access to one modern treatment, either on-demand or preventive, while seven countries have access to both.
- In Sub Sahara Africa, data indicate that two countries have access to on-demand treatment only.
These survey results represent a call to action, according to Tony. We know the challenges we face, he said.
‘The 700 HAE friends here this weekend demonstrate the growing appetite to make a difference through fierce and strategic advocacy.’
Tony concluded by inviting everyone to thank the many pharmaceutical companies that made the 2025 HAEi Regional Conference EMEA possible through their generous sponsorship:
- BioCryst, the Diamond Supporter
- CSL Behring, Pharming, and Takeda, the Gold Supporters
- Astria, Intellia, KalVista, Otsuka, and Pharvaris, the Silver Supporters
Calling keynote speaker Professor Markus Magerl to the stage, Tony and Henrik asked everyone to have fun and enjoy the conference to come.


Keynote: HAE in the Europe, Middle East, and Africa region
Standing in front of the 700 expectant faces, Professor Magerl confessed to some nerves as he introduced the theme of his talk and the 2025 HAEi Regional Conference EMEA: Embracing Opportunities.
He started by referencing the 7000 known rare diseases. Each of which was illustrated by a tiny square on his accompanying slide. HAE is, he said, just one of those squares. But it is special, because there are currently 11 licensed medications. This is outstanding in the world of rare diseases, he told the audience. For 6,830 of the 7,000 rare diseases, there is no treatment at all.
Prof Magerl posed the question: Why is HAE special in having treatment?
He said you can see an answer in the research. As late as the 1970s, the first few treatments appeared, including C1-inhibitor. Things really got a massive boost around the year 2000. Publications demonstrated increased research interest, which was immediately reflected in the introduction of new drugs. Research interest is resulting in more drugs now, and more drugs to come in the near future.
Prof Magerl suggested that the simplicity of HAE was one reason for the interest. While there may be 700 genetic mutations leading to the disease, there is one missing or faulty protein and one main symptom: swelling. HAE is also measurable in a way that means new treatments can be evaluated.
Another reason is the community of dedicated patients and physicians, as well as the collaboration between the two. Embodied by the growing partnership between HAEi and the physician-driven Global Allergy and Asthma Excellence Network (GA2LEN). “Together, we are driving up standards in HAE care with the ACARE (Angioedema Centers of Reference and Excellence) initiative,” said Prof Magerl. You can learn more about ACARE here.

So, why should we continue to work? Asked Prof Magerl, and answered “Because there is still lots and lots to do.” Most countries in this region have huge limitations on treatment. Many countries have no diagnostic tools. There remain so many questions.
‘The special recipe for success is a community of dedicated patients and physicians, and the collaboration between the two.’
To address these issues and questions, ACARE has numerous ongoing and completed projects. There are projects to phase out androgens, others to address pregnancy and HAE, and efforts to collect data in the ACARE Registry, which is nearing the milestone of 500 patients enrolled. This Registry is independent of pharmaceutical companies, Governments, and health insurers. The data is entirely anonymous and powerful.
Prof Magerl also spotlighted HAE TrackR, a free tool for patients to track their HAE and treatment. It is available in many languages, allowing almost anyone to receive a personalized treatment reminder and share data with their physician.
Prof Magerl noted that ACARE offers a wide range of physician education, which is reaching an ever-increasing number of healthcare professionals worldwide. The latest event was attended by physicians from eight African countries, which are often underrepresented in such gatherings.
In closing, Prof Magerl paid tribute to the work to date, including hosting regular meetings such as the Bradykinin Symposium and the Global Angioedema Forum in 2024. He highlighted that a group of specialist clinicians is already working on a new set of guidelines for HAE. It all highlights the potential for further improvements in HAE.
‘There are many opportunities, big and small, which we can all embrace together.’
Leaving the stage, Prof Magerl and his fellow healthcare professionals moved to the 2025 HAEi Regional Conference EMEA dedicated scientific track, which commenced with a poster presentation and associated short presentations. Click here to go to that section of our conference special. The main track continued with a roundtable featuring patient advocates on progress and lessons learned from the challenges faced.

Specialized tracks
After Professor Magerl’s keynote, the 3 specialized tracks began. The youngsters, led by Nevena Tsutsumanova and Faye Marshall, moved to their specific track to start their program. The healthcare professionals and researchers, led by the Scientific Committee co-chairs Dr Mauro Cancian, Ass Prof Emel Aygören-Pürsün, and Dr Iman Nasr, moved to their track. The patients and caregivers remained in the ballroom to kick-start their tailored program.

Embracing Opportunities – A spotlight on EMEA subregions
Joining Michal Rutkowski and Maria Ferron, two of HAEi’s Regional Patient Advocates (RPAs) on stage were 5 patients from across the diverse EMEA region: Arbia Barhoun from Tunisia, Ana Freitas from Portugal, Lina Keneciuse from Latvia, Mihaela Shogoric from Croatia, and Janice Strydom from South Africa.
The two RPAs began by asking each patient to introduce their country and HAE organization.
Ana from Portugal spoke first. She told the audience that HAE Portugal was created in 2010. They have now reached 70 members, which was driven in no small part by the emergence of new HAE therapies in the country. There are now, she said, 2 modern therapies approved and available to patients in Portugal.
Arbia, speaking in her native Arabic, said that the Tunisian organization was likewise made up of 70 patients and a group of doctors. It exists to raise awareness of HAE and to convey patients’ voices to decision-makers to obtain better care. She indicated that an important aim beyond awareness is to address misconceptions, and that advocacy means supporting patients however they need it.
Lina described her home country, Latvia, as a small Baltic state of less than 2 million people, where there are currently 13 diagnosed HAE patients. She outlined how the current treatment options are limited: there is on-demand treatment, which the Government covers, but no long-term prophylaxis therapies. There are a few doctors who do their best. Lena felt their advocacy had made a good start and would only improve by being at the conference and sharing with those around her.
In Croatian, Mihaela told the audience that HAE Croatia was formed in February 2000 through a union of friendship and a desire to help. Currently, there are 122 patients in Croatia, up from about 60 when the organization began 25 years ago.
A similar number of patients are diagnosed in South Africa, explained Janice, but their 135 patients are from a population of more than 60 million people, meaning there are approximately 1000-1200 who remain undiagnosed. Returning to the subject of misconceptions, Janice said that some South African doctors see all swelling as an allergy and treat it as such. Additionally, there is a social stigma relating to hereditary diseases, which can prevent families from coming forward for potentially life-saving diagnostic tests. The treatment landscape is extremely limited, with only one on-demand treatment being available in two hospitals. For Janice, advocacy is about making sure everyone has a fair chance of treatment, wherever they live.

Michal and Maria moved the discussion on to achievements. Janice was the first to answer. She expressed pride in how patients across South Africa had created a feeling of belonging, and how that had taken away the loneliness that often comes with a rare disease.
‘Meeting another HAE patient or family for the first time is a really life-changing experience.’
– Janice Strydom, HAE South AfricaHAE South Africa’s receipt of its first funding was a huge step in building the community in the country. It allowed them to do some simple yet essential things to take their organization to the next level, such as upgrading the website and increasing their social media presence.
The Portuguese HAE organization was proud to make a difference in its members’ lives, especially by improving access to medication and showing that they are not alone; everyone is working to reach a crisis-free life.
Lina felt personal pride in stepping up to try to improve treatment for all patients in Latvia. She described herself as a ‘beginner’, but they are already collaborating with doctors, writing letters to the Government, and developing their website with the support of their RPA, Michal.
Lina was then asked about what keeps her motivated. Her answer was her son. She wants a better and more comfortable life for him.
Lastly, Lina was asked to share one thing she’d learned in patient advocacy. She referenced the HAEi tool HAEi FocalPoint as something new she has gained a lot from. And sometimes you try something and get only a small response, but not giving up is the most important thing.
‘Remember on the days when you wake up feeling like this isn't working and you don't know why you do it, remind yourself that success in advocacy is not about the big wins or the big projects. It's about the persistence and consistency.’
– Maria Ferron, HAEi RPAArbia was asked about how she remains resilient. She remarked on the importance of working towards a shared goal by making small, manageable steps. Her motivation comes from knowing that effective medicine exists. Some countries have obtained medicine. ‘We want to be like them one day,’ she said.
Similar to Lina, Arbia felt that learning to remain optimistic is crucial to advocacy. Keeping a positive attitude and working with others are essential, she said.
Mihaela said that motivating other patients to stay involved can be as simple as ensuring there’s a new venue for a meeting; a chance to socialize can help people open up and share knowledge, even talking privately with their doctors.
Mihaela was asked to explore the changing role of digital and social media in her advocacy. She stressed the continuing importance of Facebook but said that through her relationships with people in television and newspapers, she has secured media time to tell stories about HAE.
Ana shared that the support of HAEi had been extremely important to their efforts. The future opportunity is with young people. They can make a significant contribution.
‘Young people are a hope for a new vision of HAE.’
– Ana Freitas, HAE PortugalThe hope and future opportunity for Janice in South Africa is clinical trials. They already have 28 patients participating in trials, which equates to 1 in 5 diagnosed patients.
Looking ahead, Janice suggested that while countries and Member Organizations may look very different, the challenges and solutions remain the same.
All panel members were asked to sum up their vision for the future in a single word. Ana captured the spirit across the group with the word: ‘normality’.
Thanking the panel for their contributions, all the roundtable participants left the stage, and the conference closed for the day.
Raising awareness and advocating for change
First on stage, bright and early on a Saturday morning, was HAEi Regional Patient Advocacy (RPA), Natasa Angjeleska. Her talk was to focus on raising awareness and advocating for better.
For Natasa, her own advocacy journey started when her son was diagnosed as a baby. This gave her motivation, and she was fortunate to meet people from HAEi and become part of the fledgling RPA network.
The RPA network, Natasa said, is about organizing resources and supporting Member Organizations to help the whole patient community obtain diagnoses and treatment.
She said she is often asked by individuals, “What can I do?” Her response is to start somewhere, for example, just posting on social media. Explain in simple words what HAE is and how it affects you. You can reach a lot of people through your posts being shared by family and friends.
‘What next?’ she asked. Collecting data is simple and powerful. A small survey of the number of HAE attacks in her country, North Macedonia, helped to convince the Government to fund preventive treatment, where previously only on-demand medicine had been available.
‘Data creates the evidence for your arguments. You can use it to advocate on your own and in front of Governments.’
Advocacy is everyone’s responsibility. Everyone can do something; participate in conferences like EMEA, seek support from friends or co-workers, and spread the word. Building networks, Natasa felt, creates the conditions for success in advocacy.
Another way to advocate, Natasa told the audience, is by being informed. Your primary care and emergency room physicians have limited time to learn about HAE and often know little about the disease. You can easily share information to improve their understanding. HAEi offers free emergency room posters that can help doctors (and, indeed, patients) recognize HAE.
Another way to be informed is to use HAE TrackR. This free app is a comprehensive tool to track your own disease (or that of a loved one), share information about your symptoms, attacks, and treatment, and ultimately get better care. Sharing her own experience, Natasa explained how HAE TrackR had helped her son, who at the time was having frequent attacks. Having the data to show the sheer number of attacks helped her advocate for prophylactic therapy.
This individual act of advocacy became part of a larger effort, demonstrating the need to keep setting higher objectives. Initially, the focus in North Macedonia was on securing access to on-demand medication. With that success, they re-focused on preventive therapy. Over time, prophylaxis became available, but only to children. The advocacy then shifted to ensuring that everyone who needed prophylaxis could access it. Every time it meant sharing stories, campaigning on social media, and contacting policymakers. The cycle never stopped.
It can be hard, Natasa admitted. The Friday evening panel’s energy was infectious, and she was struck by how they had different experiences but were all pushing for the same or similar goals.
She ended with a quote from North Macedonian-born Mother Teresa, who said: ‘Not everyone can do great things, but everyone of us can do small things with great love.’
‘No one should feel isolated or alone. The RPAs are there for everyone. HAEi offers a vast array of tools, information, and technology to help advocates achieve their aims.’

Ahmed’s story
The audience warmly welcomed the next speaker, Ahmed Ali Abudahir, a Libyan with HAE. Sitting with him and posing some questions was HAEi Regional Patient Advocate (RPA) Maria Ferron.
Maria started by asking Ahmed about his story and his personal life.
Ahmed’s first symptoms of HAE started when he was six years old. He didn’t know what was happening. There were frequent episodes of swelling in his hands, feet, and abdomen, some so severe that they required admission to intensive care.
Despite his suffering, there were many doctors and many misdiagnoses. A proper diagnosis took nearly twenty years. This long wait for a diagnosis, Ahmed believes, is a result of doctors’ lack of awareness about HAE. Finally, a specialist in Libya diagnosed HAE solely based on the symptoms described.
Maria asked about Ahmed’s attacks now. He described up to four attacks a month, depending on stress, physical activity, any dental treatment, or seasonal illnesses like colds. Some of these attacks are mild, while others can be severe, like a throat swelling, and require time in intensive care. In Libya, access to treatment remains very difficult and very costly, which increases the burden on patients and their families, Ahmed said.
One bright spot is HAE TrackR, a free online tool that Ahmed said he uses to get a clearer picture of his symptoms and to record every attack, including severity, duration, location, and treatment. Ahmed can create a report from this data and share it with his doctor on his terms. The data belongs to the patient, Ahmed said, which means only he decides what to share.
Ahmed concluded his story by thanking the audience for allowing him to share it. He stressed the value HAE TrackR had brought to someone like him living with HAE.

Ahmed told his story in his native language, Arabic. Using the translation tool, Wordly, during the conference, participants and Maria on stage were able to follow using Wordly on their phones.
Shaping policies and working with governments
HAEi Regional Patient Advocate (RPA), Fanny Schappler, took to the stage with a mission to demystify working with Governments and shaping policy.
She began her talk by emphasizing that achieving policy change is not a short-term activity. Changing laws and improving the way officials deal with HAE patients is a long-term project. It requires, she said, for you to be in it for the long run.
‘To get the change you seek, pack plenty of energy and plan for the long haul.’
She started by defining some important terms used when the topic of policy-making comes up:
- Policy: A set of ideas or plans of what to do in a particular situation that has been officially agreed upon by a group of authorized people.
- Policy-maker: An individual or group of people who have responsibility for setting or establishing the various roles and procedures that govern a community. Policy makers shape public policy through legislation and decision-making.
To really improve the lives and quality of life for people with HAE, the long-term solution is to change policies and laws. “It is the most effective way to increase funding for HAE, resulting in improved access to diagnosis and treatment,” said Fanny. It also means change that endures. By changing the law, people now and in the years to come will receive the support they need for their HAE.
Turning to practical ways to effect change, Fanny outlined 6 steps that everyone can take to shape policy in their country:
1. Understand how things currently work in your country
Every country and healthcare system is different. Finding the answers to questions like ‘What is the current process for drugs to be paid for?’ and ‘What are the current laws regarding rare diseases?’ helps people understand the current situation and identify what needs to change.
2. Agree on your objectives
The second step is to understand the challenge and what you want to achieve. It might be the initial steps or a 5-year plan to effect a change in the law. You decide your vision.
3. Find people to help
Policy change is not the responsibility of a single person. Identify all those who share common interests in goals. Healthcare professionals are allies, as are other groups working in rare diseases, and the media may be campaigning for change. Map all the people and organizations who share your objectives.
4. Gather the evidence
It’s vital to have evidence. Is there already published data on the situation for people with HAE in your country? If yes, you can use that data to show the problem and the need for change. If not, then HAEi is on hand to support and advise on tools and methodologies for gathering evidence through surveys and other research initiatives.
5. Communicate the evidence
Once you have your data and facts, the hard work begins. Start with compelling stories about people’s lives and the struggles they face, backed by data and facts on what is needed to make a difference. Be clear about the change you need.
6. Never give up
Policy change is a hard job, requiring long-term dedication. Celebrate every success, no matter how small. Be aware that in democracies and Governments, there is often a lot of change, with policymakers and politicians only staying in office for a limited period. This means repeating the same message multiple times.
Fanny reminded the audience that change is possible. Case studies demonstrate how you can influence national policies. “Every single one of us can make a difference, and there is strength in unity,” she concluded.
HAEi supports you every step of the way
HAEi has supported many of our Member Organizations with activities for each of the 6 steps outlined here. HAEi’s Regional Advocacy Team members are there to help you with any questions -no matter how big or small – on how to work with Governments and to shape policy in your country.
HAEi Advocacy Academy is our source of free educational courses for everyone. It provides a valuable resource for learning how to become a better advocate or advocacy leader, from engaging the media to running effective campaigns. You can learn more from your Regional Advocacy team member or HAEi.org.

Advocacy in action: A panel discussion
Fanny remained on stage to facilitate the next patient advocacy roundtable, joined by Michal Rutkowski, Director, Regional Advocacy Program.
The 6 patient advocates on stage for the session were Janice Strydom from HAE South Africa, Trine Balle Boysen from HAE Scandinavia, Bettina Carty of HAE Ireland, Dominika Słodka of Swelling Beautifully (HAE Poland), Silvana Bastri of HAE Albania and Juan Carlos Valera of AEDAF (HAE Spain).
The first question was to share some information on an advocacy activity from their respective organizations, including goals, actions, and outcomes.
Janice from South Africa spoke first. In the course of a Government decision about the availability of a modern on-demand medication, they noticed that the entire patient community had been reduced to statistics and numbers. The aim was to give HAE a real face and create empathy for patients. A series of patient videos was produced, showcasing the range of HAE and the diverse spectrum of people across South Africa affected by the disease. These included a young girl struggling to fit in with her peers at school, and a man fired from his job because of the visual symptoms of an HAE attack. Janice also told the audience that their most impactful video was of a man who had lost his daughter to an HAE attack while she was at school. “The impact of the videos was remarkable,” said Janice, “It moved our patients from being a page in a textbook to being real people deserving of urgent support.”
Trine from HAE Scandinavia gave a different perspective. For her, the challenge is motivating people to stay involved in advocacy, as countries across Scandinavia have access to modern medication and the opportunity to be well-treated. A young person suggested the idea of an app to support people with HAE as part of their HAEi LEAP project. The organization saw the app as a tool to help people remain engaged and was delighted to support the youngster with this as their LEAP project. The app, “Sums Up” was created to be a friend in the pocket when needed, offering support during challenging situations in life. It is now available on key mobile platforms.
In Spain, Juan Carlos spoke about the importance of their regular regional meetings. “These have been a considerable success,” he said, “but this year we took an extra step.” AEDAF organized a charity concert with a military band, which was also recorded for social media. In addition to the usual information sharing of a meeting, this concert provided a new way to reach people with messages about HAE.
From Ireland, Bettina discussed an awareness-raising campaign called “I Am Number 17.” This was a pharmaceutical company campaign, which told the story of people with rare diseases such as HAE, who make up 1 in every 17 people. Each patient in the campaign had a photographic portrait taken, and their story written up. These have been placed in public parks in the capital, Dublin, and are now in the national football stadium. For Bettina, it was an opportunity to bring HAE into the public eye. “If even 2 or 3 people recognise the symptoms in themselves, that will be a success,” she said. A book has also been produced for hospitals and clinicians, further sharing these vital stories.
From Poland, Dominika indicated that engaging young people was their priority. They created two workshops to ask youngsters about their needs and wants, as well as their shared difficulties. As a result, the organization facilitated a summer camp that brought young people together to freely and openly discuss their lives and challenges. The camp led to a fantastic community that has created two magazines and is giving young people the sense that there is something produced just for them.
Silvana from HAE Albania told the audience that they have been campaigning for more than 3 years for access to HAE-specific treatment. In that time, Silvana said that there had been 3 deaths from HAE in Albania. It was urgent to get treatment and dignity for people. Similar to HAE South Africa, the organization developed videos in which patients shared their stories to bring to life how people with HAE live. The stories included people who had to leave Albania to receive treatment. Ultimately, it was possible to sit down with the Ministry of Health and begin to discuss the needs of people with HAE.
Turning to challenges, Fanny and Michal asked the panel for their recollections about obstacles and what they had done to overcome them.
Juan Carlos said that in his organization, it is seen as best to approach problems step-by-step. That way, people can help out a little at a time. He recalled that Fanny had advised that advocacy is a marathon, not a sprint. “We must be prepared to keep going,” he said.
Dominika and Trine experienced shared challenges in working with young people. HAE Poland adjusted their language to ensure the summer camp spoke directly to the youngsters, making them feel like it was something they wanted to be a part of. It was about being patient and taking the time to make sure young people understood. Trine said that HAE Scandinavia created a clear plan with the youngster and checked in often; everyone was aware of what needed to be done and when.
For Bettina, the biggest challenge was that the Irish organization was relatively new, making it tricky to get new people involved. “To overcome this took courage to say yes to opportunities,” she said, “no matter how scared or uncomfortable it might feel.” It meant participating in the 1 in 17 project and having her photograph displayed in public.
In South Africa, Janice noted that courage is also a challenge. With their video project, it was essential to empower patients to tell their story with confidence. “It can be tough to look back over a life with HAE and all the setbacks,” she said, “especially for the first time.” The solution included a clear explanation of every stage, and ensured each patient had control over how much of their story they wanted to share. It gave people a sense of trust. Once people had shared their stories, they felt less passive and more that they had taken an active part in shaping the future.
The conversation moved into a more rapid-fire mode. The participants shared what they had learned and would like to share with other HAE advocates.
- For Dominika, it was about accepting that things wouldn’t be easy; they would take time, be patient, and have empathy.
- In Ireland, Bettina reiterated her message of saying yes to challenges and opportunities. “Go for it,” she said.
- Juan Carlos echoed his fellow panellists and said, “Never give up, keep going; difficulties are good, as it means that when success comes, it is all the more powerful.”
- Janice felt that the decision to hand control to their patients was a significant turning point. It meant that their powerful emotional stories could come through most clearly.
- In Albania, Silvana said it was vital to know they are not alone. They may be a small group, but through HAEi, they had powerful support. Natasa Angjeleska, their HAEi Regional Patient Advocate, was present during discussions with the Ministry of Health and has an extraordinary impact.
‘It’s better to do something than to do nothing at all. Be patient and never give up.’
– Trine Balle Boysen, HAE Scandinavia
A message from BioCryst
Delegates welcomed some new and familiar faces from the pharmaceutical company BioCryst, the Diamond Sponsor of the 2025 HAEi Regional Conference EMEA.
Charlie Gayer, the Chief Commercial Officer for BioCryst, led the 3-strong presentation team. Next to him were Abid Karim, General Manager for Europe, and Sandra Nestler-Parr, the Value and Patient Access Lead, who greeted the audience in a wide range of European languages.
Charlie gave a brief history of BioCryst, sharing that in 2019, the entire company, comprising fewer than 100 people, attended the US HAEA Summit. They were there, he said, to thank the patient community, something that remains at the heart of the organization.
‘We’ve always been so thankful to the HAE patient community, which continues to inspire us.’
– Charlie Gayer, BioCrystThe company has grown significantly since 2019 and today has around 500 employees globally, with approximately 100 supporting the HAE community in Europe. That group of people is now transitioning to work as part of a company called Neopharmed Gentili, an Italian pharmaceutical company based in Milan. The team will continue to support the HAE community and aim to help people with other rare diseases across Europe. Charlie confirmed the commitment to HAE remains unchanged.
And, Sandra noted, that commitment begins with market access. Across the EMEA region, their oral HAE treatment is available in 28 countries and counting. This level of access is just the start, with expansion in access the goal of BioCryst and Neopharmed Gentili.
‘Let’s be absolutely clear, without the amazing advocacy efforts of HAEi and its Member Organizations, we would not have been nearly so successful in our efforts.’
– Charlie Gayer, BiocrystThe BioCryst team recounted how their CEO, Jon Stonehouse, had made a further commitment: they would bring their drug to countries around the world, regardless of their ability to pay. This promise is now beginning to come true, with pilot programs in place in certain countries, and the 105 HAEi Member Organizations providing a starting map of all the countries where the company hopes to bring its medicine.
The BioCryst delegation left the stage, expressing their gratitude for attending the meeting and thanking the participants for their time.

An HAE journey and journeys with HAE: Furkhanda’s story
A British HAE patient took the audience on a journey through her life and how she manages overseas trips with her condition and medication.
Furkhanda Haxton told her fellow patients and caregivers that she is 56 years old, divorced, and lives near Glasgow in Scotland.
Although she is currently unable to work due to several medical conditions, Furkhanda has held a variety of jobs within the UK National Health Service, call centers, and supermarkets, all of which she enjoyed. Currently, she is actively involved in voluntary roles with older people, as well as contributing her time and skills to her national HAE organization, HAE UK, which she has been a part of since its inception around 15 years ago.
Before her diagnosis, Furkhanda recalls a life much like everyone else’s. Stress, dental treatment, and puberty didn’t trigger an attack. But, shortly after starting university and meeting the man who would become her husband, she began on the combined contraceptive pill. Within a month, the day after seeing the dentist, she suffered a facial swelling, which horrified her. She ended up in hospital, but it was presumed the dental anaesthetic caused the swelling. It was the first of many trips to a hospital.
Thankfully, she said, a consultant familiar with HAE saw her. He considered her symptoms and the fact that her mother had had similar swells, along with blood test results, before telling her she had HAE. It was within 10 months of her initial symptoms, which she admits is very quick.
A concern was her family. Furkhanda knew her mother had swellings, but had never seen a doctor or been to a hospital, which she felt may have been due to being part of the Muslim community. At the time of her diagnosis, Furkhanda had lost contact with her family; her determination to help her loved ones saw her write to every family doctor in the area to ask them if her family were patients. Doing this led to a diagnosis for her mother and her youngest sister.
After her diagnosis, Furkhanda started the treatment available: high-dose anabolic steroids. There was little understanding of this treatment in the context of HAE, and she was unaware of the potential side effects. She gained weight, had increased body and facial hair, and suffered episodes of intense anger, which endangered her boyfriend during an argument. She stopped the anabolic steroids.
Ill health meant Furkhanda couldn’t continue at university. However, her care improved after she switched to an immunologist who was already treating other patients with HAE. Furkhanda felt this doctor listened to her opinion, and her care improved. Sadly, this changed when she married, moved, and started a new job in one week, but, remarkably, “I didn’t have any swellings at that time,” she said. Her new consultant in Cardiff seemed to be more concerned about the cost of HAE treatment than her care. Ever resourceful, Furkhanda crossed the border with England to see a different consultant and receive the HAE-specific treatment she needed.
Furkhanda mentioned her experience with the menopause, and that she has been able to tolerate oestrogen gel and patches without triggering an HAE attack.
Furkhanda was at the start of HAE UK, attending the very first meeting where setting up a charity was discussed. Now, she is an administrator of the HAE UK Facebook community. She actively looks out for patient questions, offering guidance and answering their queries.
Turning from her HAE journey to journeys with HAE, Furkhanda recounted her first foreign trip to the Philippines. She looks back at how challenging it would’ve been if she’d experienced a swell there, but at that point, her HAE was better controlled. She admits to ‘good fortune’ while on the trip.
Furkhanda and HAEi’s top travel tips
Furkhanda provided a series of top tips for all people with HAE when traveling abroad, which HAEi completely endorses. Her checklist is:
- Contact your doctors. Request a letter explaining HAE, the necessary medication, and how it is safe (and essential) that you carry it in a cabin bag.
- Pack your medication in a separate bag and clearly label each treatment with your name. If possible, ensure you have an extra supply of medicine as a precaution.
- Get travel insurance and ensure you declare all your medical conditions. People have shared horror stories about insurers denying claims or coverage because something wasn’t clear.
- When flying, ask to be allowed on the flight early. Boarding early ensures medication is more likely to be directly to hand, and not stowed elsewhere in the aircraft’s overhead lockers.
- Use the HAEi Companion App and HAEi Emergency Cards. Furkhanda uses these to explain HAE in local languages, and you can save the Emergency Cards on a phone for immediate access. The app also provides the locations of HAE centers worldwide.
- Be aware that a long journey can lead to tiredness, frustration, and irritability, all of which can trigger an HAE attack. Ensure that on-demand treatment is available whenever possible.
The audience offered a prolonged round of applause for Furkhanda’s honest and practical story.
Stigma and cultural challenges: People with HAE panel discussion
‘Surround yourself with people who believe in you, and that support can make all the difference. You don't need a miracle. You are your miracle.’
– Jovana Cvetkovic, HAE SerbiaFor this session, a group of HAE patients and advocates from across the EMEA region gathered on stage to discuss how stigma and cultural barriers can affect the lives of people with HAE, even impacting whether they come forward for diagnosis or treatment.
HAEi Regional Patient Advocates (RPAs), Patricia Karani and Natasa Angjeleska, sat down with Ersan Sevinç from HAE Türkiye, Imad El Aouni from HAE Morocco, Jovana Cvetkovic from HAE Serbia, Yasmine Said from HAE Comoros, and Mona Askar from HAE Saudi Arabia.
The initial question asked about the challenges people with HAE face. Mona highlighted that some doctors dismissed her HAE as allergies. This delayed receiving treatment and increased her fear, especially when an attack left her in the emergency room. One of her family members died from HAE, which made it all the worse. She also raised a topic which was discussed later, that guilt about the disease can affect a person’s life decisions, such as marriage or raising children.
For Jovana, people’s first reaction to HAE is confusion. They don’t understand but want to help, so they offer advice about things like healers, herbal remedies, or prayers. People are not always negative, but a lack of understanding can lead to misunderstandings. In the past, she said her advocacy work had led people to judge her, which she said was painful and unfair.
Ersan echoed the need for people in Türkiye to think about HAE in terms of what is generally understood. He suggested people are open to learn, but words like ‘genetic mutation’ can confuse.
For Yasmin, who spoke throughout in her first language of French, one of the main challenges is the lack of knowledge among physicians, which leads to delayed diagnosis. In her case, the diagnosis took 20 years. She had to educate herself to explain it to doctors. Today, things are better, she said.
Mona echoed these experiences and said that misunderstandings around HAE also delayed proper diagnosis and treatment.
Moving on to tackle stigma directly, Imad was asked if he ever felt judged or blamed for his HAE. His response was to tell the story of another patient. It was her wedding day, and she suffered an attack for no reason. Sadly, the ceremony had to be cancelled. There were 300 guests, and the husband’s family didn’t understand HAE. They accused her of not taking precautions to prevent what they thought was just an allergy. Then there were arguments about future children and the risk of passing the disease on.
Yasmin said she had accepted the stigma that HAE caused for her family. However, she said that they learned to live with it. Yasmin’s husband provided a lot of support, and she ultimately decided not to suffer from HAE but to live with it.
‘It’s not the disease that makes me who I am, but I make the disease what it is.’
– Yasmin Said, HAE ComorosJovana described Serbia as a place where stigma often shows up in healthcare. One patient told her that he had lost friends after his HAE diagnosis, as they thought the condition was contagious. Others experienced a different problem. As the disease is often invisible, people don’t believe HAE patients are really ill; patients are accused of exaggerating or lying, which adds an extra layer of difficulty to living with HAE.
Ersan agreed with this point, especially with work. People don’t understand that you can recover quickly from an attack after taking medication. However, he could appreciate their point of view, as they don’t experience the condition.
Moving on to cultural beliefs, Ersan discussed how both European and Asian cultures influence Türkiye. In some parts of the country, there is more focus on traditional medicine, and also a deep concern about having healthy genes, which can affect marriage prospects and even starting a family.
Likewise, Imad suggested that in Morocco, some people focus on medical science while others seek wisdom in their traditional beliefs. This, he suggested, had meant people only went to see doctors when their traditional medicine had not worked.
Yasmin shared her own experience where she had to try traditional remedies first, as her family wanted to try everything possible before consulting doctors. Ultimately, she said everyone saw that remedies weren’t working and turned to medical treatment. Like other HAE patient advocates, Yasmin said people often shared their own traditional remedies. She occasionally tells people a different explanation for her HAE attacks, such as insect bites or stomach aches; Yasmin knows that isn’t right, but it can feel overwhelming to be explaining the disease to others constantly.
Asked about how openly HAE can be discussed in his community, Imad echoed Yasmin’s viewpoint. Either you take time to explain the whole story, or you invent something like an allergy, as it’s simpler.
In Saudi Arabia, there is little openness to discuss illness, Mona said. This is because illness is seen as a sign of weakness. The same thing happens in Serbia, Jovana said. It can get so bad that people choose not to go to doctors or take medication because of the shame attached to rare diseases like HAE. This can result in tragedy, with one patient dying because they pretended HAE didn’t exist because of the stigma.
Ersan added that in Türkiye, a young man died from HAE while performing his national service in the military. This led to people with HAE being excused from military service. However, Ersan knew of one young man who hid his HAE to serve in the forces and be part of his community. The individual was OK, but it shows how the disease can lead to people feeling excluded.
Imad from Morocco was asked about any ways he addresses stigma and misunderstanding. He stressed the importance of bringing people together to fight isolation.
‘Although people with HAE in Morocco do not have treatment, we do have the power of communication. We can explain HAE to reduce stigma and fight for treatment.’
– Imad El Aouni, HAE MoroccoErsan reiterated the power of community. For him, being in a community is the first step, as it removes isolation. Don’t isolate yourself, he advised other patients, it makes stigma bigger. Find others who share your experiences. Likewise, Jovana recalled growing up with her HAE being a complete mystery. When she knew there were other people just like her, it was a huge relief.
‘The HAE family helped a lot. I’m not some kind of freak. Just a bit different than anyone else.’
– Jovana, HAE SerbiaMona’s experience was to decide to live openly with her disease, as a Saudi Muslim with HAE. She believes that this illness is a test from Allah, and not a source of shame. Mona addresses stigma with knowledge and patience, and with the support of her husband and family, she is encouraged to speak freely without fear.
‘Speak up, don’t let stigma silence you.’
– Mona, HAE Saudi ArabiaLike Mona, Yasmin also gained the strength to challenge stigma from her family, especially her husband and children. She aims to keep her children from having to go through what she went through. “As strange as it seems,” she said, “HAE is a part of me and has helped shape the person I am today.”

HAEi What’s New
Executive Vice President and Chief Advocacy Officer for HAEi, Fiona Wardman, and Executive Vice President and Chief Operating Officer, Jørn Schultz-Boysen, gave a concise briefing on the latest developments in the tools, technology, and opportunities HAEi offers the community, including some projects which you might have missed.

In addition, a young person’s social media internship program is also offered, providing skills in social media, writing, advocacy, and working as part of the HAEi team. You can learn more about the social media internship here.
Pilot project in South America and Mexico
A pilot impact meeting was held in South America and Mexico. Member Organization (MO) leaders from across the region completed an intensive planning course to set out a 12-month advocacy plan. The meeting is designed to help MOs grow and increase advocacy confidence and skills. Although a pilot, HAEi hopes to run this project in other regions in the future, so stay tuned.
HAE videos to educate doctors across the Asia Pacific region
Working with HAE experts in the region, HAEi produced four short educational videos for healthcare professionals. These videos focused on the clinical aspects of the disease, including spotting symptoms, diagnosis, and treatment. You can see the complete set of videos here.
Tailored program in Brazzaville
To expand knowledge in an area with limited internet access, a team will take a video to hospitals across Brazzaville, the capital of the Republic of the Congo, to educate healthcare professionals. The videos show HAE symptoms, treatments, and what to do in an emergency. In just five minutes, physicians can get everything they need to know. This type of program could also be rolled out in other African countries where infrastructure may limit access to online education.
HAE guidelines for Pakistan
Pakistan has committed HAE doctors and a patient advocacy group. HAEi is bringing these groups and more interested stakeholders together to establish a consensus on HAE guidelines specific to Pakistan that align with current practice and available treatment options in the country.
HAEi Companion and HAE TrackR apps get a refresh
Jørn highlighted that both HAEi Companion and HAE TrackR are getting updates. These include:
- An improved user interface
- Easier download of emergency cards
- Quality of life questionnaires in HAE TrackR to aid treatment optimization
- Access to notifications through emails and text messages

Final sessions of the conference
On Saturday afternoon, the 3 tracks came together for the final sessions of the conference: Talks and Q&A with HAE experts from the 2025 HAEi Regional Conference EMEA Scientific Committee.
The situation in Kenya: HAE real-life experience
Dr Priya Bowry spoke about her home, Kenya, a country on the east coast of Africa. She said it was famous for safaris and that the HAE patients she’d met were amazing.
Dr Bowry said that whilst much has advanced in HAE care, in resource-constrained settings such as sub-Saharan Africa, very few healthcare workers know how to diagnose HAE, and diagnostic tools are largely unaffordable and unavailable. Only older drugs are available. This results in delayed or missed diagnosis and suboptimal care. All of this means, according to Dr Bowry, patients struggle, especially if they are having a laryngeal attack. They can’t reach medical facilities, and acute management is sometimes unavailable.
To illustrate the challenges, Dr Bowry drew upon a single patient with HAE, a 42-year-old lady from a rural part of Kenya called Embu. She painted a word picture of the place being near Mount Kenya, and being able to see elephants roaming nearby. This patient is a farmer who grows crops to feed herself and her family. She has limited English and a meager income, with little access to health and education.
She works on the land, which triggers swellings in her hands and feet. In the past, she has had laryngeal and facial swellings. She has been treated with antihistamines, steroids, and adrenaline, but nothing has helped. Her continuing symptoms have led to her being stigmatized by her local community, who say she is cursed or a witch.
Quite by chance, her son, studying for medical school, saw a mention of HAE in a textbook. After speaking with Patricia Karani of HAEi, the mother traveled three hours to the capital, Nairobi, to meet with Dr Bowry.
Confirming an HAE diagnosis with a C1 inhibitor test costs $150, which was this patient’s monthly salary, for just a single diagnostic test. Medicines were ‘dinosaur’ said Dr Bowry: tranexamic acid and progestin, for $80 a month. Thankfully, there is one modern HAE on-demand therapy, but without refrigeration, it is stored in a local medical facility, where every consultation comes with a cost.
Dr Bowry summed up the challenges:
- There is limited literacy and capacity
- People are poor. They lack basic access to technology to access information or store medicines
- The knowledge of healthcare professionals is limited
- There is poor health literacy, poor drug compliance, and support
- There are social and cultural factors that mean rare diseases are stigmatized in African culture
Ultimately, Dr Bowry said, education is the only way forward. To date, HAE has been included in National Guidelines, which was a massive step. Engagement with stakeholders, such as pharmaceutical companies, can expand access through programs for low- and middle-income countries, as well as through clinical trials.
‘For HAE, the time to change is now.’

10 things people with HAE need to know
At the 2025 HAEi Regional Conference EMEA, Professor Danny Cohn from the Netherlands spoke on the ever-popular topic of 10 things people with HAE need to know.
1. He opened his presentation with the first thing: Look ahead
While this can’t happen all the time, Prof Cohn asked people with HAE to prepare in advance. He gave the example of a dental procedure being booked for 8am on a Monday. This might be fine, but if you need help with the administration of short-term prophylaxis, the home care service will likely be closed, meaning there’s no one around on Sunday or Monday morning to help.
Other examples included stressful situations such as a driving test and making plenty of plans ahead of any travel.
2. Moving on: Don’t wait to diagnose
Prof Cohn said he had spoken to many families that had delayed getting tested or an HAE diagnosis for their son or daughter, in the belief that they didn’t want to bother the child. He stressed the importance of thinking about what might happen: What if the child goes on a trip, has an attack, and no one knows what to do?
We should not forget that HAE is a potentially fatal condition. While not all forms of early testing may be available to everyone in the EMEA region, it is important to consider testing as soon as possible rather than waiting to see what happens.
3. Next: Seek specialized and comprehensive care
Prof Cohn recounted how people with HAE had had to explain the disease to their physician, rather than the other way round. But if you look for a physician who has experience in the disease and its care, your story will sound familiar.
4. Have your emergency plan ready
Another way to get the best care is to have an emergency care plan ready. He told the story of an HAE patient who needed to go to the emergency room during an attack. His care was delayed by more than an hour because the junior doctor who saw him had to ask his supervisor, who then had to ask another hospital. If an emergency plan is ready, it can help avoid delays and unnecessary or incorrect treatment.
5. Importantly: The future looks bright
Prof Cohn described both the progress made in HAE and what the future holds as ‘mind-blowing’. He said that people with HAE can face the future knowing that things will really be different from the past.
6. Don’t blame yourself for an HAE attack
It’s common, Prof Cohn said, for patients to say that their attack was their own fault; they went out with friends while fatigued and had an abdominal attack. Or, they went mountain biking and had a genital swelling. It’s really unfair to blame yourself for an injury or an attack, he said.
‘It’s our joint task as patient and physician to enable you to do whatever you want and not suffer attacks.’
7. HAE should not affect your life
Prof Cohn told the story of a family that had avoided amusement parks and rollercoaster rides due to a fear of triggering abdominal attacks. This family, thanks to appropriate long-term prophylaxis, now does whatever they like, including skiing holidays.
8. You are in control, was Prof Cohn’s next ‘thing’
You are the one who decides if an HAE attack needs treatment, or if you need to call in sick, or whether to take part in an activity or event. It’s much better, if you can, to be in control by being able to self-administer your own on-demand treatment, Prof Cohn advised.
9. Don’t wait to treat an attack
Prof Cohn showed statistics demonstrating that the sooner you treat an attack, the less severe it is likely to become and the sooner its symptoms will be relieved. Don’t wait to treat your attack, Prof Cohn suggested: ‘When in doubt, treat.’
10. Realize you’re not alone!
Prof Cohn saluted the work of patient advocates across EMEA and the activities of HAEi in bringing people together to share experiences. The more we share and talk about our experience, the more others can learn to help better manage their HAE.

Latest developments in HAE
Dr Mauro Cancian spoke to the audience about the latest thinking in the treatment of HAE.
He started by reminding the audience of how far we’ve come in understanding the disease. Just 13 years ago, a modern, innovative classification of HAE was proposed. It called for just a few groups, whether hereditary or acquired, and whether caused by histamines (as for allergies) or by bradykinin in the case of HAE. Now, he said, there has been an enormous progression in diagnosis, making the classification very complex, sometimes even for experts, leading to an understanding of the genetics behind all forms of HAE. However, HAE with C1-inhibitor deficiency remains the most common form.
Dr Cancian dived straight into the first of his 5 topics.
1. Therapeutic targets and management strategies in HAE
Dr Cancian outlined how important it is to understand how a disease occurs to treat it effectively. He described the chain reaction that occurs in an HAE attack, when prekallikrein is activated, splitting bradykinin from high-molecular-weight kininogen and leading to gaps between endothelial cells in blood vessels, fluid leakage, and swelling.
All of that chain reaction, called the contact pathway, he said, was an opportunity to target a different level of the system.
When considering therapies and drugs for HAE, it is important to be aware of 4 key points. Dr Cancian explained these are:
- Target: Which part of the process that leads to an attack will you focus on
- Technology: How will you produce the medicine
- Administration: Will it be an injection, a tablet, or something else
- Indication: who will it be available for, and what will it aim to do (treat or prevent attacks, for example)
2. On-demand therapy
Turning to the existing treatment landscape, Dr Cancian listed the on-demand therapies, which he said remained the mainstay of treatment for all patients. These include plasma-derived C1-inhibitor, icatibant (which works on bradykinin), and kallikrein inhibitors such as sebetralstat.
3. Long-term prophylaxis
For short and long-term prophylaxis, plasma-derived C1-inhibitor was described, while for long-term prophylaxis alone, Dr Cancian listed donidalorsen, lanadelumab, berotralstat, and garadacimab. One special area of consideration is the potential for oral treatment, typified by berotralstat. Beyond this, the different medicines are administered at different timescales, which can be important to patients and the effective management of the disease.
4. Emerging treatments
Dr Cancian suggested new therapies for both on-demand and long-term prophylaxis were needed, as none of the available drugs work for every patient 100% of the time.
Looking at upcoming treatments, Dr Cancian mentioned deucrictibant as interesting, as it may work as both a preventive and a treatment for attacks. This could be achieved by changing the rate at which the medicine is absorbed into the body, either to provide long-term protection or to resolve an attack on demand.
Dr Cancian also described navenibart, which may only need to be taken infrequently to prevent attacks; ADX-324, which acts in an innovative way to prevent attacks; and NTLA-2002, which is a gene therapy currently being trialed. Gene therapy would unlikely be for every patient, Dr Cancian cautioned, but could work by silencing the faulty gene in people with HAE. It might represent a lifelong treatment.
5. Unmet needs and open questions
Finally, Dr Cancian turned to continuing challenges. He highlighted that in much of the world, there are few HAE-specific and effective treatment options to prevent or resolve attacks. Androgens (steroids) are still used, but while they may offer some effectiveness, they can lead to side effects, including high blood pressure, weight gain, and male hormone issues in women. Where necessary, androgens should be started at a very low dose.
Other issues included treating special populations, such as the very young and the elderly, especially those taking other medications at the same time. It will also be important to personalize the concepts of total control and the normalization of life, and to understand what this means in real life for different people.

HAE in women, pregnancy, and children
Professor Henriette Farkas was invited to give a talk on HAE in women, pregnancy, and children, which are always eagerly awaited topics.
She started by thanking the audience and HAEi for the opportunity to speak, before dedicating her presentation to the memory of some of the inspirational physicians who had devoted their lives to understanding HAE and improving its care.
Women and HAE
Across all types of HAE, more women than men are affected, Prof Farkas told the audience. Additionally, females tend to have more frequent and severe attacks, most likely as a result of the impact the hormone estrogen has on the kinin-kallikrein system, which leads to bradykinin production. The use of estrogen-containing oral contraceptives increases the frequency and severity of HAE attacks. For this reason, Prof Farkas suggested that these contraceptives should be avoided in women with HAE. Other options, such as barrier methods or the progestin-containing oral contraceptive, should be used instead.
All targeted treatments for HAE can be safely administered in females and males, Prof Farkas told the audience. However, androgens should be used only with caution in female patients as these can lead to side effects, including weight gain, hair growth, and changes to the menstrual cycle.
A key trigger for HAE attacks is menstruation, with 68% of cases being linked to a woman’s period. Additionally, Prof Farkas presented a slide that showed that sex hormones change over time, which can mean that HAE symptoms worsen during puberty, but may decrease during the menopause. This is not clear-cut, however, and some patients experience more frequent attacks during menopause. Hormone replacement therapy (HRT) may cause worsening of HAE symptoms, Prof Farkas counselled.
Pregnancy
Overall, there is no consistent change in HAE among all women during pregnancy; some report experiencing fewer attacks, some report a greater number, and some report no change at all. According to Prof Farkas, all three trimesters of a pregnancy may feature attacks, and abdominal attacks may occur more frequently. Perhaps surprisingly, Prof Farkas indicated that giving birth is rarely the cause of an HAE attack. However, breastfeeding has been associated with increased HAE attacks.
The only treatment recommended during pregnancy, post-partum, and during breastfeeding is plasma-derived C1-inhibitor. Fresh-frozen plasma and solvent-detergent plasma represent second-line options for acute treatment and short-term prophylaxis. Androgens are not recommended during pregnancy as they can affect the developing fetus.
For a natural delivery, short-term prophylaxis with intravenous plasma-derived C1-inhibitor is only a consideration (not a recommendation). However, for complicated deliveries, the same short-term prophylaxis treatment is recommended.
Children with HAE
Prof Farkas opened the final part of her talk by asking: What makes pediatric HAE patients unique? Her answer suggested that as children grow, their bodies undergo lots of changes, which can make it challenging to diagnose and treat HAE. She said it was uncommon for clinical symptoms to occur in a fetus or in infants. Only one case has been published on angioedema in the womb, she said. However, half of patients experience their first attack before the age of 18, and the early onset of symptoms may predict more severe HAE attacks.
In terms of symptoms themselves, the most common and often the earliest symptom is swelling in the extremities, with a prodrome of itching, which can lead to a misdiagnosis of urticaria. Additionally, as abdominal pain is a common symptom in children, it can lead to abdominal attacks being misdiagnosed.
Importantly, because of the smaller airway, a laryngeal or throat attack may develop quickly in children.
To diagnose HAE in children, Prof Farkas outlined that C1 and C4 levels can be measured, as in adults. However, in children under 1 year of age, the complement system is underdeveloped, which may result in lower-than-normal readings.
Prof Farkas advised that families with children with HAE need to ensure that everyone involved in the care of the child, such as teachers, are given written information about the disease and can recognize an attack. As soon as they are old enough, patients should be trained to self-administer HAE treatment and be aware of an emergency care plan.
As children reach adulthood, this can be a complicated and challenging time for their HAE care. Prof Farkas suggests that any transition should be planned for. Ideally, the whole family will be cared for in a single center.
In general, the treatment approach to HAE in children is the same as in adults. The use of therapies to prevent attacks, but to have medication on hand to treat and resolve attacks if they occur.
Prof Farkas highlighted that the WAO/EACCI guidelines recommend:
- As prophylaxis, plasma-derived C1-inhibitor and lanadelumab for children
- To treat attacks, plasma-derived and recombinant C1-inhibitor, and icatibant for children and adolescents
- For adolescents, the same long-term prophylaxis medication is recommended as for adults: plasma-derived C1-Inhibitor, lanadelumab, and berotralstat. In the US, ecallantide is available for adolescents.
Prof Farkas concluded by sharing that new guidelines on the management of HAE in children have been developed and submitted for publication this year. She ended the talk by telling the audience that by working together a great deal more can be achieved.
NB: There are recently approved HAE medications not yet included in the guidelines. The approvals and licensed indications for HAE medicines can vary across countries and regions worldwide. People with HAE and caregivers are encouraged to always seek medical advice to understand what is available and recommended for use in their country.
Currently, oral deucrictibant is being trialed to treat attacks in adolescents with HAE in the RAPIDe-3 trial. Sebetralstat is being tested to treat attacks in children (2-11 years old) with HAE. Berotralstat and garadacimab are also being trialed in children (2-<12 years old) to prevent HAE attacks. Navenibart is being tested in adolescents with HAE as prophylaxis.
Prof Farkas concluded by sharing that new guidelines on the management of HAE in children have been developed and submitted for publication this year. She ended the talk by telling the audience that by working together a great deal more can be achieved.

Questions for the expert panel
To close the patient track, an expert panel of HAE physicians was assembled to answer questions from attendees. This esteemed panel comprised the 2025 HAEi Regional Conference EMEA co-chairs, Dr Mauro Cancian, Ass Prof Emel Aygören-Pürsün, and Dr Iman Nasr. It was chaired by Professor Markus Magerl, who posed the questions, which were grouped into three topics: living with HAE, medication, and other queries.
Before the expert panel went on stage, Debs Corcoran, HAEi’s Director, Research, took the chance to ask Professor Farkas two questions related to her expertise in women with HAE.
The first question was: Can HAE attacks fluctuate with the hormonal cycle? Prof Farkas felt that this was the case, as menstruation is a common trigger for attacks, so someone susceptible to hormonal changes could see more or more severe attacks.
Secondly, Debs asked: What is the recommendation on stopping treatment when you want to get pregnant? Prof Farkas suggested that any patient taking androgens should stop if trying for a baby. Beyond this, Prof Farkas indicated there is limited experience beyond a recommendation to use plasma-derived C1-inhibitor. Trials are ongoing to see if other treatments are safe in pregnancy, such as lanadelumab.

The first question for the panel, which was estimated to have between 50 and 100 years of combined HAE experience, was: Can you cure HAE forever?
The panel suggested that even with the potential of gene therapy, it is currently not possible to say that someone is cured of HAE. There might always be a breakthrough attack. However, the panel agreed that with modern long-term prophylaxis, it is possible to achieve complete control of the disease and a normal life for patients, free from the symptoms of HAE.
An audience member asked: Does HAE get more severe from generation to generation, such as from grandmother to granddaughter?
The panel said that HAE is highly variable. There are reports from patients that while a relative had a very severe form of the condition, for others, there were only mild symptoms.
Can food trigger an HAE attack?
The panel felt that an underlying food allergy was a more likely explanation. One of the panel members recalled a patient who loved to eat nuts but always found himself having an attack when he ate them, until he received long-term prophylaxis. Now he can eat nuts without any consequences for his HAE.
Can HAE patients donate blood or organs?
The panel was happy to recommend blood donation. There was a single report of a woman who was diagnosed with HAE after receiving a liver transplant from an HAE patient. For them, this was a special type of acquired angioedema. The panel suggested that there may be case-by-case decisions, but they would still say that HAE patients should be able to donate blood or organs.
Does a healthy diet and exercise reduce attacks?
The panel all shared anecdotes of how a healthy diet and physical activity had helped their patients. In particular, reducing the inflammatory response by losing weight can improve HAE attacks. Overall, the panel strongly recommended a healthy diet and exercise to their patients.
What are the risks of going deep-sea diving?
The panel was limited in their own diving experience, but still suggested that, with effective long-term prophylaxis, any activity should be possible for people with HAE. However, they cautioned that the stressful nature of some dive sports may increase the risk of attacks.
Can I get a tattoo as an HAE patient?
Yes, the panel said. In their experience, many patients had had tattoos with at most mild swellings following the procedure. Long-term prophylaxis should make this another normal part of life for people with HAE. Of course, joked one panel member, you can get a tattoo if you want, and your mum agrees.
What will happen with my HAE if I need hypersensitization therapy for wasp stings?
The panel was clear that no medically required procedure should be avoided in HAE patients. The procedure, which is undertaken to limit a dangerous overreaction by the body to wasp toxin, can be managed with on-demand treatment and long-term prophylactic medication.
Are there studies of the long-term effectiveness of lanadelumab?
The panel said that yes, there is evidence and data that confirms the long-term efficacy of lanadelumab as prophylaxis for HAE. More broadly, there is no suggestion that any HAE treatments lose their effectiveness over time. In effect, people with HAE do not develop resistance to treatment.
Should an oral treatment or an infrequent injection be chosen for a 13-year-old with HAE?
The panel agreed wholeheartedly that the best choice here is the one made by the young person with HAE. If you want someone to take their medication long-term, it should be the medication they want to take.
Does a medication always have the same effect on the entire body?
The panel highlighted that acute treatments for attacks work faster for mucosal attacks, such as those in the throat or gut.
The last question in the time allowed was: How do I know I’m seeing the right doctor?
The panel suggested that every HAE patient should feel comfortable questioning their doctor about their knowledge of the condition and its treatment. Additionally, by looking at the HAEi and ACARE websites, you can check if your doctor is part of an accredited center.

Scientific Track
The scientific track
Running concurrently with the Patient Track, the Scientific Track of the 2025 HAEi Regional Conference EMEA was the hub for the scientific data and clinical discussion on the diagnosis and treatment of HAE. The Scientific Track was chaired by three physicians from across the EMEA region: Dr Mauro Cancian from Italy, Ass Prof Emel Aygören-Pürsün from Germany, and Dr Iman Nasr from Oman.
The Scientific Track opened with a poster session showcasing some of the latest research in HAE.
Are you looking for scientific data from the conference?
If you want to read more about the wealth of scientific data presented at the 2025 HAEi Regional Conference EMEA, 33 abstracts are available online.
Friday evening poster session
The Scientific Track of the 2025 HAEi Regional Conference EMEA opened with the customary short oral talks from selected posters. These talks covered a wide range of topics related to the treatment and care of people with HAE, with each presenter given 2 minutes to explain their scientific work concisely.
42 abstracts were submitted and 33 accepted for presentation: 5 as oral presentations and 28 as posters.
Posters with short oral talks
Impact of delayed treatment
The first to present was Alexis Bocquet from France, who showcased research on the impact of delayed treatment of HAE attacks. His research was conducted among people in 4 European countries. The study found that delaying treatment led to more severe attacks, and the impairment of quality of life was greater. He suggested that the delay may be due to difficulty in recognizing an attack and a desire to reserve treatment for more severe attacks.
Genetics of HAE in Ukraine
Speaking next was Anastasiia Bondarenko from Ukraine, who talked through their data on the genetic characteristics of HAE in Ukraine. She told the assembled healthcare professionals that their work has tested 25 patients from 15 families in Ukraine. Of these people, 14 had a mutation of the SERPING1 gene. And even in this small group of patients, they found a mutation that occurred in two independent families, and one patient with a confirmed mutation of the Factor XII gene.
Results of an expanded access program for berotralstat
Paola Triggianese, from a hospital in Rome, Italy, spoke about the results of an Italian expanded-access program on berotralstat for the prevention of HAE attacks. They showed that the proportion of patients who were attack-free following treatment with berotralstat significantly improved at 3 and 6 months. Additionally, the patient’s quality of life improved.
Hereditary angioedema in Sub Saharan Africa
Priya Bowry from Kenya spoke to the audience about the landscape for HAE in sub-Saharan Africa. She indicated that data on the situation for people with HAE in the region is severely lacking. They asked physicians to indicate the number of diagnosed patients and the available tests and treatments. She concluded that there is a significant problem with underdiagnosis of HAE in the region and limited information and knowledge about the condition. She called upon those present to assist in access to trials.
Transient hepatitis after danazol discontinuation in HAE
Mats de Lange from the Netherlands presented data on what happened to HAE patients who stopped taking danazol, after seeing a patient treated with the drug suffer a transient form of hepatitis. In this study, they showed that shortly after stopping danazol, all five patients surveyed had significant changes in their liver enzymes; however, none had hepatitis or liver failure, and all liver enzymes normalized within 17 weeks without any treatment. He concluded that awareness of the potential impact of discontinuing danazol is important for physicians and may lead to changes in how patients are transitioned off the drug onto newer therapies.
Long-term safety and efficacy of deucrictibant
Anna Valerieva from Bulgaria presented some of the results from the RAPIDe-2 extension clinical trial, which investigated how well deucrictibant worked to treat HAE attacks. She indicated that they now have data from 465 attacks, which show an initial improvement within 1.1 hours and total resolution of an attack within 10.6 hours.
Tackling unmet needs in HAE
Patrick Yong from the United Kingdom presented research on addressing unmet needs in HAE and optimizing care and treatment. He explained that the authors produced a policy paper calling on the UK government and policymakers to change how things are run to improve access to modern HAE therapies. This included more flexibility in the eligibility criteria and a focus on improving the UK healthcare system for people with rare diseases.
Unfortunately, Dr Gunel and Ass Prof Guilarte were unable to give the short talks with their posters. Global Perspectives caught up with them to ask about their work.
The prevalence of C1 inhibitor antibodies in acquired angioedema according to etiology
Nur Selvi Gunel from Türkiye shared research on the diagnosis of acquired angioedema (AAE). The data presented concerns the use of a form of laboratory test (indirect ELISA (Enzyme-Linked Immunosorbent Assay)) to identify antibodies that could be present in a blood sample. The findings suggest that this antibody-testing method can provide valuable information and may enhance diagnostic accuracy.
Efficacy and safety of donidalorsen for hereditary angioedema among patients in Europe: A regional subanalysis of the Phase 3 OASIS-HAE study
Ass Prof Mar Guilarte from Spain shared two different works at the 2025 HAEi Regional Conference EMEA. In the first, the focus was on analyzing patients treated with a potential new medicine for HAE, called donidalorsen. The findings indicate that the medicine significantly reduced HAE attacks, improved overall quality of life, and had an acceptable safety profile. The research concluded that this demonstrated that donidalorsen could be used for HAE in Europe.
Clinical simulation improves HCP confidence in managing patients with HAE
The second work, Ass Prof Guilarte told Global Perspectives, demonstrated the potential value of an HAE-related simulation to improve healthcare professionals’ knowledge and confidence in managing HAE. The findings from a post-workshop survey indicated that participating HCPs reported that the workshop, called HAE360, improved their knowledge and confidence and led to adjustments in their clinical practice.
Scientific session, Saturday
On Saturday morning, the assembled physicians had a full program of presentations and discussion.
Tony Castaldo, HAEi CEO and Chairman of the Board, and Henrik Balle Boysen, HAEi President, offered a warm welcome to the clinical experts and pharmaceutical company teams who had taken time to attend the Scientific Track. The two HAEi leaders recounted how far knowledge and treatment of HAE had advanced, and the huge contribution of scientists and clinicians to these advances.
‘I think collectively everyone in this room should be very proud of the fact that an ultra-rare condition called HAE now has 11 regulatory-approved medications. That’s unprecedented and a credit to this community.’
– Tony Castaldo, HAEiCo-Chairs welcome and Young Researcher Award
Following a welcome from the Co-Chairs, the Young Research/Investigator Award was presented on-stage to Dr Mats de Lange from the Amsterdam UMC.

In his words: Dr Mats de Lange, Young Researcher Award Recipient
As the latest recipient of the HAEi Young Researcher/Investigator Award, Global Perspectives caught up with Dr de Lange to ask him about the award and his interest in HAE.
Global Perspectives: Congratulations on the award. What did it feel like to hear that you and your work had won?
It felt like an enormous surprise and a moment of recognition when I heard that our team’s work had won the Young Investigator Award. The fact that it came from HAEi made it even more meaningful, because it shows that the work connects not just with scientists but also with the patient community.
Global Perspectives: As a rare disease, HAE might not be the first thing scientists and clinicians decide to focus on in their careers. What made you choose to focus your work and research on HAE?
HAE wasn’t something I learned much about during medical school. But once I started working as a medical doctor in the hospital, I saw how disruptive and unpredictable the disease can be for patients. As soon as a PhD position in bradykinin-mediated angioedema opened, I seized the opportunity to be a part of a fascinating and quickly evolving research field.
Global Perspectives: Finally, what were your impressions of the 2025 HAEi Regional Conference EMEA?
It was a very positive experience. Presenting my research and connecting with researchers from other countries in our region was great, but especially getting in contact with people living with HAE and hearing their stories and perspectives was really valuable.
HAE in EMEA: Perspectives
The first session was a chance for representatives from countries in the diverse regions of Europe, the Middle East, and Africa to describe the local situation and their perspectives on HAE management.
Northern Europe
The representative from northern Europe was Ass Prof Emel Aygören-Pürsün from Germany. She started by describing a situation in Germany where around 1600 diagnosed HAE patients are treated in 22 centers. The German HAE patient association was one of the earliest patient communities, and the first HAEi meeting took place in the German city of Frankfurt.
Turning to treatment, Germany was able to access effective long-term prophylaxis in 2011, but C1-inhibitor concentrate had been available since 1979. Many modern forms of prophylaxis are now licensed and reimbursed in Germany, including home administration of intravenous C1-inhibitor. Studies indicate that home-based treatment led to earlier treatment and faster initial symptom relief.
Southern Europe
Dr Mauro Cancian, from the Conference host nation, Italy, spoke about the experience in Southern Europe.
He opened by acknowledging the fundamental importance of a good relationship between patients and clinicians to managing HAE. The ITACA network is the result of this in Italy, where doctors and patients collaborate to raise awareness and educate about the disease.
Dr Cancian highlighted in particular the efforts they make to educate pediatric doctors about the disease, as HAE is commonly spotted in childhood, but there is often a delay in diagnosis. There are now about 1150 patients diagnosed with HAE in the Italian HAE registry, with new patients added regularly.
For the management of HAE, Dr Cancian spoke of plasma-derived C1-inhibitor, icatibant, lanadelumab, and berotralstat. He expressed hope that garadacimab and sebetralstat will soon be available. Despite this positive picture, there were continuing issues, Dr Cancian said; the average interval from EMA approval to availability is 2 years due to price negotiations. There are also limits on treatment, with only more severely affected patients being prescribed certain medicines. Regional variations across Italy’s north, south, east, and west also limit access.
Africa
Dr Leith Belkahia from Tunisia was the representative from Africa. Speaking via video, he began by noting that before 2008, no cases of HAE had been reported in Tunisia. In the years since, 78 patients have been diagnosed across 15 families, which, he said, really supports the importance of family screening. Despite these advances, the average diagnostic delay remains 21 years, reflecting limited disease awareness and a lack of diagnostic tools.
In terms of management, Dr Belkahia indicated that a multi-disciplinary team of doctors and nurses has been trained to improve patient care, and dedicated weekly consultations provide specialized care to families with suspected HAE. Currently, there is only one laboratory (in Tunis) capable of conducting functional C1 inhibitor testing, which limits diagnosis.
Fresh-frozen plasma has been used successfully to treat abdominal and laryngeal attacks, and icatibant has received some approval.
A pilot project in which a small team of doctors travels to more remote parts of Tunisia to screen families for HAE was also described. This was described as a promising development, but Dr Belkahia concluded by saying that HAE remains a little-known disease in Tunisia, with a high mortality and a long diagnostic delay. He called for continued screening efforts and made clear that long-term prevention remains limited to tranexamic acid and danazol.
Middle East
The final perspective came from Prof Elham Hossny of Egypt. In contrast to the preceding situations, Prof Hossny told the audience about Egypt’s vast population, some 100,000,000 people. Despite this, she said, at her tertiary referral clinic, they have diagnosed 23 children. Her adult colleagues have identified around 38 cases. This lack of diagnosed cases, she suggested, can be attributed to a lack of awareness amongst healthcare professionals. However, the picture is improving. In 9 years, only 17 cases were diagnosed. In the last 18 months, there have been 6 children diagnosed with HAE.
Dr Hossny drew attention to the challenges of undiagnosed or late-diagnosed HAE. She referenced that 6 of her patients had a positive family history, and 5 of these reported a death in the family. Indeed, in one family, 3 children had died from HAE. This is why, she said, they are screening the families of children with HAE. They also screen patients with recurrent unexplained angioedema.
In terms of treatment, plasma-derived C1-inhibitor and lanadelumab are available, along with fresh frozen plasma and danazol. However, Dr Hossny indicated, not every patient can access long-term therapy unless they have severe attacks.
A major challenge for Egypt in managing HAE is the cost and availability of diagnostic tests. In pediatrics, Dr Hossny highlighted the significant impact HAE can have on the lives and ambitions of young people. One young girl told her she didn’t want to go to school as she feared attacks and had no treatment. But even in adults, the burden can be extreme. Dr Hossny described how she was moved to tears when a mother told her, ‘I saw my husband die in front of me from suffocation. I don’t want to see my child die.’
This burden is part of the reason Dr Hossny works so hard to support the HAE community. She indicated that she is in daily contact via WhatsApp with a group of more than 800 members who ask questions about HAE. Additionally, she and her colleagues in Egypt have already conducted 21 training events for healthcare professionals. Dr Hossny is a core part of efforts to improve care in the country.
Members of the Scientific Committee joined our presenters, and a panel question-and-answer session followed the four perspectives. Questions were raised about the pricing of HAE therapies, the availability of medicines in Gulf countries such as Oman, and the importance of implementing local guidelines for HAE treatment. Another topic for discussion was the risk of viral transmission using fresh frozen plasma. The panel suggested that this could be mitigated through robust testing of blood bank stocks.

Abstract oral presentations: Session 1
The Scientific Track then turned to the first of two oral presentation sessions on HAE-related research.
1. Clinical Validation of a Novel Kinin Biomarker Assay to Characterize Bradykinin-Mediated Angioedema. Professor Henriette Farkas, Hungary
Prof Farkas presented on the validation of a novel biomarker assay to characterize bradykinin-mediated angioedema, which she described as probably a game-changer in the diagnosis of bradykinin.
The need for further diagnostic tools is most pressing, according to Prof Farkas, in HAE with normal C1 inhibitor. However, detecting biomarkers for any disease related to bradykinin is a major challenge, as its half-life is less than 30 seconds.
Prof Farkas said the study examined the feasibility of tracking bradykinin using a new method. They recruited 13 patients with HAE with C1-inhibitor deficiency and another with a plasminogen genetic variant (HAE with normal C1-inhibitor deficiency). The new procedure used a cold process to effectively measure bradykinin levels, which were elevated in both types of HAE patients compared with healthy controls.

2. Results From the ALPHA-STAR Trial, A Phase 1b/2 Single and Multiple Dose Study to Assess the Safety, Tolerability, Clinical Activity, Pharmacokinetics, Pharmacodynamics, and Immunogenicity of Navenibart in Participants with Hereditary Angioedema (HAE). Dr William Lumry, United States of America
The following oral presentation was on data on a potential new treatment for HAE, called navenibart. Dr Lumry gave a brief history of HAE treatment, noting that on-demand intravenous (IV) and subcutaneous (sc) treatment has been augmented by long-term IV and sc injections to prevent attacks, as well as daily oral treatment. This study, he said, examined the potential to further reduce patients’ treatment burden by using a medicine that lasts longer in the body.
The trial was, he said, a small one. Still, it showed that navenibart was well tolerated. Out of 16 patients across 3 different cohorts receiving treatment, the most common side effect was a blocked nose or headache, and treatment-related side effects were primarily injection-site reactions. The therapy reduced attack frequency effectively.
Dr Lumry concluded that navenibart demonstrated a favorable safety profile and no dose-related treatment-emergent side effects. Navenibart showed a 94 to 100% median reduction in monthly attack rates compared to the patient’s baseline, and has the potential to be an effective and safe prophylactic medication for HAE with administration every 4 or 6 months.

The patient perspective: UK and Kenya
Prof Danny Cohn introduced the next session, dedicated to giving healthcare professionals first-hand experience of what life is like for people with HAE. The speakers were: Patricia Karani, HAEi RPA for Sub Sahara Africa and an HAE patient from Kenya, and HAEi Board Member and UK-based HAE patient, Rachel Annals. Debs Corcoran, HAEi Director of Research, facilitated the discussion.
Debs asked Rachel and Patricia for their memories of the first time they knew that something wasn’t right.
Patricia remembered regular swellings, but, as a young child of 8, it was put down to youthful bumps and scrapes. She also knew that she got swellings like her grandmother, father, and two brothers, but no one knew why.
For Rachel, her memories of swellings start earlier than Patricia’s. She recalls being sick a lot. Her earliest memories also involved getting swellings in her hands and feet. She said she missed a lot of school and felt very different from her friends. She was self-conscious and would try to hide her swellings with bandages. Sometimes her feet were so swollen she couldn’t wear shoes.
The next question was about medical help. Patricia said that when she was at boarding school, there was a nurse. But the nurse wasn’t happy to treat Patrica’s swellings, so her parents often had to come and take her to the hospital in the middle of the night. The doctors she met didn’t know what to do about the swellings, which made her think that they might kill her. She had a throat swelling which almost led to her being intubated (a tube inserted into the windpipe to aid breathing).
Rachel recalls going undiagnosed for 13 years and seeing so many different doctors. The most common suggestions for a cause were allergies or migraine. She tried special diets to eliminate allergies. She hated feeling different and waiting for answers. When the diagnosis came, it was at the end of a private clinic appointment her parents arranged and paid for. The doctor suggested HAE almost as an afterthought. Following a blood test, HAE was confirmed.
For Patricia, it was a similar chance encounter. At a hospital visit, a doctor knew what Patricia had. Sadly, his advice was that there is no cure and no medication. From diagnosis to despair in a sentence, but for Patricia, it was just a relief to have an answer.
Rachel shared the sense of relief. She said she didn’t even care what treatment she had; just to feel normal again was her goal. Steroid medications kept her attacks under control and literally changed her life.
With a diagnosis also came the opportunity for family screening. Rachel’s father and grandmother tested positive for HAE. Even a great-grandmother was diagnosed with the disease after a lifetime of swellings.
Patricia’s route to treatment was more challenging. A brother in the US also received a diagnosis of HAE. He received medication, and this motivated Patricia to seek help. She eventually found Dr Priya Bowry, who handled her case, and had the relevant tests performed, which confirmed HAE. She received the prophylactic medication available at the time. She felt more positive and no longer feared that HAE could kill her.
In closing, Debs asked both Patricia and Rachel what they’d like doctors to know.
- Patricia wanted all the doctors present to know that not all swellings are histamine-related. ‘Keep HAE in mind if antihistamines aren’t working,’ she said.
- Rachel told the audience that her message would be that every HAE patient is different. Each patient needs to be given time to be listened to and understood. ‘We want our experiences to be taken seriously, so that each of us can choose the medication that best fits their life,’ she said.

HAE differential diagnosis
Professor Andrea Zanichelli from Milan, Italy, gave the next lecture, dedicated to differential diagnosis in HAE. He started by looking at the recent history of diagnosis and understanding of HAE as a disease in which a chemical pathway in the body doesn’t work properly, leading to a deficiency of C1-inhibitor and consequent swelling from fluid leaking out of blood vessels and into the tissues.
Despite this, Prof Zanichelli said, patients still face a long delay in diagnosis, averaging 8 years, and some more than 10 years. In that time, almost half of patients are misdiagnosed, as the symptoms of HAE look like those of more common conditions, such as abdominal attacks being mistaken for appendicitis.
Also important, Prof Zanichelli said, was distinguishing between HAE and other forms of swelling caused by allergic reactions (mast cell-mediated). The diseases may look similar, but the mechanisms are very different. HAE is not itchy. It does not respond to allergy medicines. It often has no clear trigger, unlike mast cell-mediated angioedema.
To start with, Prof Zanichelli suggested asking about urticaria (itching). If there’s swelling with itching, then it’s probably allergic angioedema. If there’s a response to antihistamines or a more specialist drug called omalizumab, it is unlikely to be HAE.
The next step would be to check if the angioedema is caused by the use of a medication, most commonly a class of heart medications known as ACE-inhibitors. If that’s not the case, and especially if there’s evidence of a family history of unexplained swellings, then suspect HAE.
The presentation then extended into diagnostic tools and tests for HAE, including C1-inhibitor levels and the function of C1 and C4. This could also support a diagnosis of HAE with normal C1-inhibitor when an appropriate genetic test is conducted.
Finally, Prof Zanichelli presented a case study to illustrate differential diagnosis in angioedema.
Questions from the assembled audience followed the presentation, including whether CT scans and ultrasound are reducing the incidence of HAE misdiagnosis and the challenges of diagnosing solely based on abdominal symptoms.

Abstract oral presentations: Session 2
The Scientific Track then returned to the final 3 oral presentations of HAE-related research.
3. Long-Term Prophylactic Treatment with Deucrictibant for Angioedema due to Acquired C1-Inhibitor Deficiency. Dr Mats de Lange, Netherlands, the 2025 HAEi Regional Conference EMEA Young Researcher award recipient
This research investigated a disease estimated to be 10 times rarer than HAE, a form of angioedema in which there is no genetic mutation; instead, the normal bodily response goes wrong, and the levels of C1 inhibitor in patients become too low to prevent swelling attacks. Currently, there is very little clinical research into this condition and its treatment. Dr de Lange’s research trialed the investigational HAE medicine deucrictibant as a preventive treatment for angioedema due to acquired C1-inhibitor deficiency. Their research among 4 patients showed that deucrictibant enabled all patients to achieve total disease control, with 3 of the 4 patients having no attacks during the trial period.

4. Sebetralstat for On-Demand Treatment of Hereditary Angioedema Attacks in European Participants: Interim Analysis from KONFIDENT-S. Dr Teresa Caballero, Spain
This research examined the effectiveness of a (at the time of presentation) recently approved medication for HAE, sebetralstat. It investigated 69 patients trialing the medicine to treat HAE attacks. In total, the study examined 999 attacks. Dr Caballero showed that symptom relief began at 1.6 hours, severity decreased at 6.8 hours, and complete resolution occurred at 21 hours. There were no serious side effects of treatment. Dr Caballero concluded that the drug resulted in rapid end of progression of attacks, early symptom relief, reduction in attack severity, and attack resolution.
In a subsequent question, Dr Caballero indicated that there were no concerns about taking this oral medication on an empty or full stomach, nor were gastrointestinal side effects likely to be more common.

5. Lanadelumab’s Enduring Impact on HAE Attack Reduction and Improved Disease Control: Final Results from the Enable Study. Prof Andrea Zanichelli, Italy
In the final oral presentation, Prof Zanichelli returned to the stage to present data on the efficacy of lanadelumab in the treatment of HAE. He showed that 138 patients were recruited across 18 sites in Europe and Israel, and the study lasted 2 years. At the end, the authors concluded that patients reported a marked and sustained reduction in attack rate over time. Patients were treated for more than 2 years, but from month 1 onward, the threshold for a patient to consider their disease under control was met and remained so. Prof Zanichelli concluded that the study reinforced the evidence that lanadelumab can be used as a first-line treatment for HAE prophylaxis.

Round-table: Real-life experiences and discussion
Prof Laurence Bouillet took the audience through a patient case study, joined on stage by members of the Scientific Committee. Prof Bouillet posed questions to the panel based on the case presented, and the panel shared their own final reflections on the management of HAE.
Key topics covered included:
- The use of an emergency helpline for healthcare professionals on HAE and angioedema
- Danazol should not be used to treat HAE attacks
- The importance of patients having at least two doses of an effective on-demand treatment, such as icatibant, in the event of an attack
- The role of patient and caregiver education and training in self-administration, including through intravenous injection
- Gradual or immediate discontinuation of danazol for patients when HAE-specific long-term prophylaxis becomes available
- Treatment choice in the event of a pregnancy
At the conclusion of a lively discussion and debate, the Co-Chairs thanked all speakers, panelists, and participants for a productive Scientific Track. Following lunch, the physician delegates joined patients and caregivers in the Patient Track for further presentations and discussion.

On Saturday afternoon, the 3 tracks came together for the eagerly anticipated talks and Q&A with HAE experts from the 2025 HAEi Regional Conference EMEA Scientific Committee.
Youngsters Track
EMEA youngsters embracing opportunities
Friday evening – welcome to EMEA!
The first session of the 2025 HAEi Regional Conference EMEA HAEi Youngsters’ Track started in a lively fashion, with introductions to a fun-filled and welcoming (except for moms and dads) space for young people to enjoy and express themselves.
Presenting the HAEi Youngsters’ Community
Nevena Tsutsumanova, HAEi Manager, Events and Special Projects, and the driving force behind the HAEi Youngsters’ Community, invited all of the almost 90 young people to relax and enjoy the next few days of learning and laughing together. She asked Dominika, Winona, Eirini, Ania, and Daniella from the HAEi Youngsters’ Advisory Group to explain the community a little bit.
‘The Youngsters’ Track is the place where the advocacy leaders of tomorrow are made.’
– Nevena Tsutsumanova, HAEiThe young advocates asked the audience to think about what community means to them, with answers ranging from teamwork to family and a sense of belonging. They then provided a brief run-through of programs available to youth advocates to learn more and gain skills, including social media internships, the HAE Let’s Talk podcast, and many volunteering opportunities.
Some fun questions followed, even asking the young people to invent the name for an HAE superhero, with Swell Girl winning!
Welcome to HAEi LEAP 2026
Nevena returned to the stage, this time joined by Debs Corcoran, HAEi Director, Research. Between them, they explained the LEAP (Learn, Experience, Advocate, Pave the way) program, which is open for applications in 2026. They encouraged young people to think about putting in an application, in combination with their Member Organization, as the rewards in terms of education and financial support to progress a passion project were real.
Debs then provided a sneak preview of some of the education available in LEAP. Time management might not seem the most exciting topic, but delivered with heart and enthusiasm, it captivated the young people.
‘Strong communication skills underpin great time management.’
– Debs Corcoran, HAEiThe Friday session drew to a close with the chance for the young people to share food and experiences before joining everyone for dinner.
Saturday session
Young people with HAE and youth caregivers assembled once again on Saturday morning, where the uniqueness of the experience was discussed. In this space, no one needed to explain HAE or their own life; everyone present will understand.
Getting to know each other
The morning started with a brief icebreaker session, in which young people were invited to learn more about their fellow participants, particularly by finding out each person’s ‘golden egg’, or something hidden about them. One participant even shared that their father took part in the Eurovision Song Contest!
Welcome from HAEi Leadership
The Youngsters’ Track then welcomed HAEi’s Executive Vice President and Chief Operating Officer, Jørn Schultz-Boysen, and Executive Vice President and Chief Advocacy Officer, Fiona Wardman. Both secretly expressed their wish to be in the Youngsters’ Track rather than being stuck in with all the grown-ups, but knew they weren’t allowed. The HAEi leaders encouraged everyone present to take the opportunity to make new friends, renew old friendships, and get the most out of the sessions.
Before leaving, Fiona and Jørn shared what they feel are the qualities of a good advocate. These were:
- Be persistent
- Be kind
- Never give up
- And perhaps most importantly, keep smiling!
The power of advocacy
Nevena led a session in which young people were given insights into what advocacy means and how advocacy, even the actions and words of just one person, can make a difference. The talk drew upon the lives of some famous advocates, including:
- Mahatma Gandhi, who challenged injustice through peaceful means
- Malala Yousafzai, who faced violence just to call for the right to education
- Nelson Mandela, who forgave those who oppressed him and millions of others
- Havana Chapman-Edwards, who made a stand against gun violence
- Rick Hansen, who highlighted the challenges of travel for people with disabilities
None of these people was born an advocate. They become advocates because they believe in something and stand up for it. Nevena encouraged everyone to feel confident in their own ability to create change, whether big or small.
Face2Face with an HAE expert
The agenda moved on to an eagerly anticipated session, where HAE experts, Professor Danny Cohn and Professor Markus Magerl, answered questions posed by young people. Prof Magerl spoke with those aged 12-17, while Prof Cohn chatted with those aged 18-25.
Questions were wide-ranging, but there were many about traveling with HAE (something you can read more about in the patient track write-up). Prof Cohn suggested that before heading away, people with HAE should talk to their doctor; a change in medication or dosing might make the trip easier and more enjoyable. A follow-up query related to what to do when traveling to a country with no HAE-specific medication. Prof Cohn suggested making sure to be informed about what can be done in an emergency, even if it’s treatment with fresh frozen plasma.
That led on to a question about what frozen plasma is. Prof Cohn explained that it is the part of human blood that contains proteins but no blood cells. This naturally includes some C1-inhibitor from the human donors, so by giving large amounts, you can replace the missing C1-inhibitor in the blood of people having an HAE attack.
A young person asked whether there are other diseases linked to HAE that people with the condition might also have? Prof Cohn said he wasn’t aware of anything. Hives are often mentioned as a super common issue, but they are not linked to HAE.
There was a question about tattoos, a popular topic at HAEi conferences, and when treatment might be needed following the procedure. Prof Cohn suggested that if a patient is well-controlled on long-term prophylaxis, then just having an on-demand treatment available in case of a breakthrough attack will be enough, but this depends on the individual and their HAE.
One youngster asked: ‘How should a young patient approach talking to their doctor, especially if the doctor can be intimidating?’ Prof Cohn admitted that he understood how intimidating some doctors can be, but that many doctors, like him, work very hard to be open and welcoming. He said the key thing to keep in mind is that you matter. You are the one with HAE, taking treatment and living your life.
At this point, Faye Marshall, a nurse specialist and HAEi’s frequent poet collaborator, shared her perspective as a healthcare professional and someone who also lives with a rare disease. She asks her clinicians, “Can I tell you what’s most important for me?” This gives the young person the chance to say how they really feel and explain their own life, hopes, and ambitions.
Back onto treatment, Prof Cohn was asked about the usefulness of combining treatments. His view is that if one treatment isn’t working, combining different therapies for HAE could be helpful. However, this is again something very individual for patients.
A youngster asked what doctors do to earn their patients’ trust. Prof Cohn said he couldn’t speak for every doctor, but he and many others start by proving themselves. With every new patient, he schedules their first appointment at the end of the day so he has as much time as possible to listen and understand without distractions. It is actions like that which show how much the doctor cares and is engaged in the best care for people with HAE.
A final, very thoughtful, question was posed about when to draw the line between being a patient and being an advocate. For Prof Cohn, that could only be a personal decision. Some things might impact it, such as whether there’s a long family history of HAE or if the young person is the first in their family to have the disease and needs to advocate for themselves constantly.
Guided conversation: Voices of change
Faye Marshall picked up the microphone, this time as the facilitator of a conversation about HAE advocacy and living with the condition as a young person. She welcomed onto the stage Ognen from North Macedonia; Ania from Poland; Noa from the Netherlands; Daniella from Mozambique, and Winona from South Africa.
‘I think being part of this community also inspires us. We could hold a pity party and feel sorry for ourselves. But then you're surrounded by these people who travel all around the world, have these conversations, and connect.’
– HAEi YoungsterThe focus, Faye said, was on the journeys people have taken with HAE, whether as patients or caregivers.
A lively discussion followed, covering the following topics:
- What makes people feel powerful? With answers ranging from not being scared to express an opinion, music, exercise, setting achievable goals, and helping other people.
- What to do with bullies or people who would make you feel small? Have a small part within yourself that knows what makes you feel good, and tap into it whenever you are troubled. Also, the importance of not letting others use anything you think is a weakness.
- What to do about change? The group discussed how change can trigger HAE, but it can also spur new opportunities.
- How to talk to people about HAE? This included being clear that HAE can be part of your identity, not a burden to be carried, and the importance of diagnosis as a potential source of joy for those seeking answers.
The panel shared their final thoughts: don’t be shy and spread kindness whenever you can.
The Youngsters’ Track ended with all participants taking part in an exercise to find and hold on to small gestures, acts, or phrases that have made them feel stronger, and to create ripples of change through the things they will do to improve the world in which they live.
On Saturday afternoon, the 3 tracks came together for the eagerly anticipated talks and Q&A with HAE experts from the 2025 HAEi Regional Conference EMEA Scientific Committee.
hae day :-) is around the corner!
Introducing a new human resource for Member Organizations to call on
16 May is hae day :-), our annual celebration of the HAE community and a key focus for awareness-raising efforts. Our activity challenge continues to record the steps you generate—solo or as part of a team—through your time spent on physical and wellbeing activities. As you prepare for hae day :-) 2026, our haeday.org website has lots of practical information to help you plan your media engagement, community involvement, or social media, as well as lots of inspiration for activities carried out in previous years by our Member Organizations (MOs).

Ahead of hae day :-) 2026, we’re delighted to announce that, starting now, our MOs can call on a new human resource – Natasha Jovanovska Popovska – as they plan their activities. Natasha is HAEi’s newly appointed Coordinator, Program Implementation and Engagement, and hae day :-) is one of HAEi’s programs in her remit.
Global Perspectives caught up with Natasha to find out more about her new role and how she can help MOs with their hae day :-) activity planning.
GP: Can you tell us a little about your new role?
My role is Coordinator, Program Implementation and Engagement, which means I will act as a liaison and resource for our 100+ member countries for various HAEi programs. One of those is hae day :-), and I’m excited to be in this position to help unite our global HAE community around 16 May.
Specific to hae day :-), I’m here to assist our MOs in planning, implementing, and promoting their hae day :-) activities to help ensure their efforts have maximum impact.
GP: What are you looking forward to most in your role?
I’m most looking forward to working closely with our MOs around the world and seeing the amazing creativity and passion they bring to their advocacy each day. I also hope that through additional support for their advocacy efforts, MO leaders feel empowered and recognize that their initiatives play an essential role in strengthening the HAE patient voice, visibility, and influence within their national healthcare landscapes.
Year on year for hae day :-), our MOs find new and innovative ways to raise awareness. My role further strengthens HAEi’s ability to help bring people together and facilitate a global exchange of ideas, which is incredibly inspiring.
Knowing that our collective efforts on hae day :-) can ultimately lead to a better quality of life for people with HAE is what truly motivates me. I’m excited to connect with others, share in their enthusiasm, and make a real difference by spreading awareness globally.
GP: How can you help MOs with their hae day :-) activities?
I anticipate helping MOs in several ways:
- Guidance and ideas: I can support MOs in planning and implementing their hae day :-) activities — whether large or small — by helping them brainstorm ideas, tailor approaches to their country’s needs, and make full use of the resources HAEi provides, such as media templates, awareness materials, and social media graphics.
- Amplifying MO activities: I will also encourage MOs to continue to share their event details, photos, and stories so we can highlight them on haeday.org.
- Personal support: I’ll be a personal point of contact for any questions or issues. No matter how big or small the question, an MO can contact me, and I’ll do my best to help solve the problem.
“A journey of a thousand miles begins with a single step,” and my goal is to help MOs take that first step. I’m here to remove barriers, offer practical guidance, and amplify the celebration of everyone’s efforts.
GP: How can MOs contact you if they have a question about their hae day :-) activity?
MOs can contact me in a few ways. They can email me directly at n.jovanovska@haei.org, or they can go through their Regional Advocacy team member, who will loop me in as needed.Or, we have a new contact form on our hae day :-) website.
Whether it’s a quick question or more detailed guidance, please don’t hesitate to get in touch — I’m here to help make your hae day :-) activities as successful as possible.
Update from the HAEi Youngsters’ Community
The last few months have flown by! Our LEAP 2025 youngsters are working hard on their projects with their Member Organizations, and we’ve been busy launching the next round of applications for the LEAP class 2026! By the time you read this, the applications will have closed, and we’ll be looking forward to welcoming a fresh new group of students to make up our class of 2026.
The HAEi Youngsters’ Advisory Group put together a great youngsters track at the 2025 HAEi Regional Conference EMEA. 91 young people came together for a fun, engaging, and inspiring program, and you can read all about the track and the inspiring work of the youngsters here.
Members of the HAEi Youngsters’ Advisory Group got the chance to meet at the 2025 HAEi Regional Conference EMEA. We are planning the next round of our Youngsters Community Social Media internship and great new episodes of our HAE Let’s Talk! Podcast. Stay tuned to our newsletter – sign up here – and Instagram account @haeiyoungsters.
‘We’re proud to celebrate three exceptional Youngsters’ Advisory Group members who are moving forward into new opportunities and adventures. Thank you, Isabel, Jess, and Dominika, for everything you’ve contributed—your passion, ideas, and dedication have shaped our community. We look forward to cheering you on in this next stage of your journey.’
– Nevena Tsutsumanova, Manager, Events and Special ProjectsOn behalf of Global Perspectives, Nevena got the time to talk to one of the recent HAEi Youngsters Advisory Group alums, Dominika, and asked about her journey with the Youngsters’ Community and the Youngsters’ Advisory Group (YAG). You can also read about what’s next for Dominika in her own words, just after the interview. The Youngsters’ Community isn’t saying goodbye but ‘see you soon’ as Dominika will always be an honorary part of, and a good friend to, this community.
Do you remember the moment you joined the YAG, and what was your motivation for it?
I remember when the YAG was created and started doing activities for Youngsters. I was so impressed and in disbelief that living with HAE can look like that. I then wanted to be a part of that. It’s easy to become a Member of YAG if you are involved in advocacy.
How has being a part of YAG and the Youngsters’ Community changed you over the years?
I’m a different person than I was in 2017, before the Summer Camp in Frankfurt. Working with so many amazing, creative, diverse, and inspiring young people has contributed to my personal growth. I have always been a shy person, and talking with others stressed me out.
‘However, my HAE family made me feel special, even when speaking in a language that isn’t my first. I had the chance to meet people from different backgrounds, experiences, and cultures, which opened my eyes to the world.’
– Dominika SłodkaDid being part of YAG prompt you to be more involved with your Member Organization in Poland?
Being part of YAG definitely prompted me to become more involved in my organization, Swelling Beautifully. I showed them they could count on me, and they gave me opportunities to participate in conferences, workshops, and camps. It’s always a two-way street.
What are the top 3 things you remember and want to share with the community?
- You need to remember that HAEi Youngsters’ Community is a family. You can reach out to us whenever you need, even if it’s to talk or ask for an opinion. We are here for you.
- Having HAE doesn’t make you “different”; it makes you special.
- Always remember to be You. You can always be honest, and you won’t be judged.
What’s the best trip you remember, and what made it so special?
I can’t say just one trip was the best because every trip I took with HAEi and the YAG was the best. They were always full of love and laughter. One that was really special for me was the 2023 HAEi Regional Conference EMEA in Munich. On the first day of the conference, it was my birthday, and on the Youngsters Track everyone sang me a happy birthday. It’s a small thing, but it made me feel really special. It showed other Youngsters that we do care for each other, and that the community is more than just a few people meeting. It’s family.
My time with the HAEi Youngsters – Dominika’s story
Growing up as a teenager with HAE was definitely a difficult experience. My whole life, I thought only my brother and I had HAE. That was until I got a call from Michał Rutkowski of the Pięknie Puchnę (Swelling Beautifully Association) in Poland, asking if I was interested in attending a Youngsters Summer Camp in Frankfurt. I was in total shock when I saw almost 70 youngsters with HAE. It really opened my eyes! There were so many amazing young people facing the same challenges as me. It felt like we had known each other for years.During the 2018 HAE Global Conference in Vienna, I had a chance to help create the first HAEi Youngsters magazine and website. We talked about our personal experiences and made a plan to help people with and without medications. It was awesome to bring so many people together from every corner of the world for such an important cause.
These two events showed me how a young person can be involved in advocacy. As a result, I became a member of the Youngsters Advisory Group (YAG) in 2020. I’m an introvert, so I was afraid that it would be a challenge for me. I was so wrong. Since the first meeting with the YAG, I felt part of a family. With HAE, you might sometimes feel different, but in this community, you can feel ‘normal’.
Since 2020, I have taken part in many events and activities. I represented Youngsters at the 2022 Global Leadership Workshop in Frankfurt and then the 2024 meeting in Copenhagen. I also attended the 2023 HAEi Regional Conference EMEA. We exchanged knowledge, experiences, and contacts. We have also met with international experts and listened to other people’s stories. Knowing we are not alone has changed everything for many. Every HAEi meeting brings a huge smile to my face! It gets me so excited for the future. I have made so many friends I can relate to and contact when times are difficult. As a YAG member, I had the chance to help get others involved in advocacy, for example, as a Social Media Intern.
I’ve also been fortunate enough to take part in the amazing LEAP project. Thanks to Nevena and Debs Corcoran, who run the program, I learnt skills which helped me create the first HAE Poland Youngsters Summer Camp. It was focused on getting to know each other and learning about your HAE. We held a session with two HAE specialists and a psychologist. Working together in groups allowed us to create the first-ever HAE Youngsters Polska Magazine! For our second event, we wanted to do something different. That’s why we invited HAEi’s Director, Research, the amazing and creative Debs Corcoran. We wanted to offer Polish Youngsters a fresh perspective on aspects related to HAE. For example, Debs focused on showing them how they can lead a less stressful life just by learning to manage their time.
My time with the HAEi Youngsters’ Community has come to an end. I’ll continue my advocacy journey. Working with young people and seeing how passionate they are was a really amazing experience. I’m so grateful that I had a chance to be a part of it. What a journey it has been. I loved every second of it.

Still haven’t joined the HAEi Youngsters’ Community?
The HAEi Youngsters’ Community is free to join and is open to young people with HAE, family members, caregivers, and friends who are part of their country’s HAE MO and are between 12 and 25 years old.

From Zoe Steiner, Operations Coordinator, HAE Australasia
HAE Australasia: Strengthening Connections and Looking Ahead
HAE Australasia continues to evolve and grow, with exciting developments across advocacy, patient engagement, and strategic partnerships.
Representing Our Region at ASCIA 2025
In September, HAE Australasia was proud to be represented at the ASCIA 2025 Conference in Brisbane by Fiona and Zoe. This three-day event provided an invaluable opportunity to connect with pharmaceutical companies offering treatment options for patients with HAE, as well as a range of clinicians and fellow patient advocacy organizations from across the region.
Notably, our board member and clinical expert Professor Connie Katelaris attended and delivered an insightful presentation to delegates. We were also delighted to see Dr Hilary Longhurst from New Zealand sharing her expertise in an engaging session that further strengthened trans-Tasman collaboration. These discussions and connections help us drive forward improved care and access for HAE patients throughout Australasia.

2026 Sydney Patient Meeting in the Works
Looking ahead, we are excited to announce that planning is underway for our next major Patient & Carer Meeting, scheduled for February 2026 in Sydney. This conference aims to bring together approximately 60 patients and carers from across Australia for a program of education, support, and community connection.
We’re currently finalizing venue and program details, and look forward to opening registrations soon. We’re also actively engaging with sponsors and are pleased to already have a number of supporters on board to help make this important event possible.
A Fresh Look for HAE Australasia
In line with our continued growth and evolving role in the HAE landscape, HAE Australasia is undertaking a comprehensive brand refresh. Our current logo, color palette, and printed and online materials have served us well, but are due for an update to reflect the modern, forward-thinking organization we’ve become.
The new branding will feature a simple, contemporary theme designed to better align with our mission to improve both preventative and acute care management options for our community. Stay tuned as we look forward to sharing the new look with you in the coming months.

From Ahtashamul Habib Ovi, National Contact, HAE Bangladesh
HAE Bangladesh is steadily growing as more patients are connecting with our community.We are pleased to announce the launch of our new member organization website: bangladesh.haei.org. Hosted by HAEi, the new site provides a wealth of knowledge and resources for patients, including information on HAE symptoms, management strategies, and educational courses.
A list of local HAE specialist physicians, along with their contact details, has been added to help patients easily reach out for medical support.
The website’s resource section also features recordings of our previous webinars. Patients and physicians who were unable to attend can now access these recordings to gain valuable insights shared by experts and participants.
Another exciting development is the completion of Bengali translations of HAE patient materials. These translated documents, available on the HAEi website, make it easier for Bengali-speaking patients to learn about HAE and its management in their native language.
We look forward to connecting with more patients across Bangladesh and reminding them that they are not alone in their journey with HAE.

From Daphne Dumbrille, HAE Canada
As we welcome the fall season, we are pleased to share our activities of summer 2025.
An exciting development came in August when Health Canada authorized the new subcutaneous treatment, garadacimab, for use in Canada. This milestone represents a meaningful advancement for people living with HAE, providing a new treatment option that can help manage symptoms and improve quality of life. Following this authorization, in September, Canada’s Drug Agency (CDA)—the national body responsible for reviewing clinical evidence and providing recommendations on whether new treatments should be publicly reimbursed—released its Draft Recommendations for garadacimab. We were pleased to see CDA recommend reimbursement for patients with HAE types 1 and 2. However, the recommendation did not extend to patients with HAE with normal C1, leaving this group without public coverage. HAE Canada submitted detailed feedback urging CDA to reconsider this decision and ensure that all patients who could benefit from garadacimab have access. We look forward to learning the CDA’s final decision in the coming months and remain committed to advocating for equitable access for everyone in the HAE community.
In addition to treatment advocacy, the Board of Directors took an important step to strengthen our government relations and public policy efforts by partnering with a national lobbying organization. This team brings extensive experience in rare diseases and public policy, which will be invaluable as we work to address ongoing challenges in access to care. Specifically, they will help us focus on improving treatment options for nC1 HAE patients and tackling the deductible changes that accompanied the introduction of generic icatibant. Once onboarding and planning meetings are complete, we will work closely with this team to develop a comprehensive advocacy strategy aimed at making our efforts even more effective and impactful.
Education and awareness continue to be central to HAE Canada’s mission. To support our members in sharing accurate and reliable information about HAE, we provide a range of handouts and resources designed to empower patients and educate communities. Thanks to the support of the Canadian HAE Network (CHAEN), which represents physicians who treat people with HAE across the country, we are excited to release newly updated materials. These include an infographic, a tear sheet, and a brand-new HAEC brochure, all available on our website. These resources are designed to help patients and caregivers communicate confidently about HAE, raise awareness in their communities, and advocate effectively for their needs.
This summer also provided valuable opportunities for learning and global connection. In July, three HAEC Board members, Michelle Cooper, Kim Speiss and Carmen Craciun, were grateful to attend the HAEA Summit in Baltimore, Maryland. With well over 1,000 attendees, the conference offered an inspiring showcase of the power of connection, youth engagement, and family-focused programming – key elements in building a strong and supportive community. Creative vendor spaces, innovative patient services, and sessions on advocacy and patient support illustrated how vision, dedication, and teamwork can make a meaningful difference. Our Board members returned with renewed energy and insight, inspired by the ways HAEA’s commitment to advocacy and community-building truly transforms lives. Attending the Summit reinforced the importance of staying connected with international organizations and bringing new ideas and best practices back to our Canadian community.

Three Board members, Michelle, Carmen, and Kerstyn Lane, and one staff member, Daphne Dumbrille, attended the Canadian Society of Allergy and Clinical Immunology (CSACI)’s Annual Scientific meeting in beautiful Vancouver, British Columbia. To help increase awareness among Canada’s treating physicians, HAE Canada had a booth to provide attendees with information about HAE and HAE Canada. The meeting was well attended by physicians and industry from across Canada. On Saturday, the physicians who presented at the Plenary Symposium on HAE, Drs. Susan Waserman, Paul Keith, and Marc Riedl did a fantastic job educating attendees about the latest information on HAE, with presentations focusing on management of C1 Normal HAE, new available treatments ,and updates of the new Guidelines. We are pleased to learn that Dr. Alejandro Palma from Dalhousie University in Halifax, Nova Scotia, was awarded the Canadian Allergy, Asthma and Immunology Foundation (CAAIF) – Canadian Angioedema Scholarship Program (CASP) – KalVista Research grant for HAE to explore biomarkers for clinical heterogeneity in HAE. Congratulations to Dr. Palma!

As we move into the fall, we remain committed to our mission of supporting patients, raising awareness, and advocating for equitable access to treatments. We are grateful for the dedication of our members, volunteers, partners, and Board, whose collective efforts make progress possible. Together, we will continue to stand beside our community, working to ensure that every person with HAE has the support, resources, and access to care they deserve.

From Carlos J Carvajalino M, HAE Colombia
In the middle of the Cundiboyacense plateau, a vast Andean plateau located in the Eastern Cordillera of the Colombian Andes, the municipality of Toca became a meeting point for knowledge, community, and hope on August 16. The association for HAE in Colombia (AEHCO) came to this rural community to raise awareness about a hidden but profoundly human condition: hereditary angioedema (HAE). The event was the result of weeks of coordination with the Toca Municipal Government, in a joint effort to open spaces for dialogue about health, rights, and visibility in areas where information is still scarce.
Before: Listening, Understanding, and Preparing the Ground
Preparation for the meeting began with identifying local needs and seeking institutional partners. AEHCO conducted a preliminary review of health conditions in the municipality, detecting barriers to accessing specialized services, underreporting of rare diseases, and a lack of awareness of care pathways. These findings guided the design of an educational presentation tailored to the rural population, focusing on early recognition of HAE and the importance of its differential diagnosis compared to other common conditions. The goal was simple but crucial: to open conversation and generate interest where there had previously been only silence.
During: Sharing Knowledge and Awareness
The event took place at the House of Culture, with the presence of the mayor, community representatives, and families who came to learn about this rare disease. The opening was marked by a message of unity: the recognition that rare diseases are also part of public health and deserve attention. AEHCO offered an interactive presentation on HAE, using clear language and everyday examples that facilitated understanding. The session addressed symptoms, possible triggers, management approaches, and the importance of mental health in the process of adapting to the diagnosis. Although time did not allow for the practical workshop on crisis management, the conversation generated a collective reflection on the need to strengthen medical and community education to detect potential cases early.
Afterward: A network that begins to grow
As a result of the session, AEHCO appointed Martha, a local leader recognized for her social commitment, as an AEH community ambassador. Her role will be to serve as a liaison between the association and the municipality’s rural communities, facilitating early symptom detection and supporting new families seeking guidance. This connection represents a fundamental step toward the sustainability of fieldwork and the remote follow-up of potential patients. In the following months, AEHCO will continue to provide technical and emotional support through virtual meetings and low-cost educational materials.
A gesture that leaves a mark
The visit to Toca confirmed an essential truth: change begins when information is delivered with empathy. A few days later, AEHCO commemorated the day on its social media with a message that encapsulates its spirit: “Toca welcomed us with open doors and an open heart… we built a community, sowed knowledge, and continued to strengthen a network that is built step by step, person by person, where every gesture counts.” This phrase summarizes the purpose of each outing: to transform ignorance into awareness and distance into collaboration. In Toca, Boyacá, a community opened its hearts, and AEHCO built a bridge of trust so that no one living with HAE ever feels invisible again.
Looking Ahead
With this experience, AEHCO reaffirms its commitment to continue traveling through the country’s rural areas, supporting the communities most in need, and building knowledge from the ground up. Toca, Boyacá, thus becomes a symbolic starting point for strengthening early detection of HAE and consolidating local support networks. Every encounter, every story, and every conversation confirms that health education is also a form of social justice: an opportunity for medical knowledge and human empathy to work together toward a more informed, supportive, and visible future for people living with rare diseases in Colombia.

From Camelia C. Isaic, Czech HAE Junior z.s.
HAE Junior raising disease awareness among medical students in the Czech Republic
At the invitation of ČAVO (Rare Diseases Czech Republic), our organization, HAE Junior, took part in the ‘University lectures’ educational project at the beginning of October 2025. Through seminars and lectures, this project seeks to introduce medical students to the life experiences of patients with rare diseases. During the lecture held at the 2nd Faculty of Medicine, Charles University in Prague, a brave HAE Junior representative shared her story describing both the disease experience and the challenges faced on her patient journey. Such insight gave the medical students a unique opportunity to learn about hereditary angioedema from the patient’s perspective and ask questions directly. At the same time, the future doctors were able to find out more about HAE Junior’s awareness projects and activities.
Our patient organization regularly joins similar events dedicated to educating medical students. For example, last year we held a similar presentation at the 3rd Faculty of Medicine of Charles University in Prague, also at the invitation of ČAVO. We also displayed a drawing exhibition by children with HAE at the Faculty of Medicine of Masaryk University in Brno (2023) and the 2nd Faculty of Medicine of Charles University at Motol University Hospital in Prague (2022). In addition, we previously distributed to all medical faculties in the country the printed Czech version of the educational poster ‘Not all angioedema is caused by allergies’, issued by HAE International and translated into Czech by HAE Junior.

From Priyanka Meduthuri, HAE India
The newly upgraded website of the HAE India Patients Association (HAEIPA) represents a significant advancement in digital outreach and patient support for individuals living with HAE in India.
Designed with improved accessibility and navigation, the website now features a comprehensive, state-wise directory of knowledgeable HAE specialists, enabling patients and caregivers to connect with appropriate medical expertise across the country.
This milestone coincides with HAEIPA’s first official Board Meeting, conducted in accordance with HAEi’s international principles of good governance, underscoring the association’s commitment to organizational transparency and structured leadership.
Furthermore, plans are underway for a patient meeting in Kerala, aimed at fostering engagement among patients, physicians, and caregivers. The upgraded website – haeindia.haei.org – reflects HAEIPA’s enduring dedication to enhancing awareness, education, and support for the HAE community throughout India.

News from Parichehr Bahraini, HAE Iran
Donation of C1 Inhibitor Concentrate Delivered to Hereditary Angioedema Patients in Iran
The Immunodeficiency Patients Advocacy Association (IDPA), in collaboration with the Immunology, Asthma, and Allergy Research Institute (IAARI) and the Vitan Pharmed pharmaceutical company, successfully secured and distributed a donation of C1 Inhibitor concentrate to provide free treatment to eligible patients with Hereditary Angioedema (HAE) in Iran.
The C1 Inhibitor concentrate, which is the first-line therapy for managing and preventing HAE attacks, remains expensive and is not covered by insurance in Iran. This financial barrier limits the medication’s availability and affordability for most patients, as it is imported only in small quantities.
During this initiative, conducted about two months ago, IDPA arranged to supply a limited number of C1 Inhibitor vials – each valued at around 200 million Rials – free of charge to eligible patients, significantly easing the access challenge for those who need this critical medication.
Patients who received the medication were provided with detailed training on its proper use, including timing and administration during acute attacks. Each patient was also given written instructions to ensure safe and effective use of the drug.
At that time, patients were instructed to visit the IAARI clinic on Mondays or Wednesdays to obtain a prescription from Dr. Mohammad Reza Fazlollahi, an allergist and clinical immunologist, and then to collect the medication from the Children’s Medical Center pharmacy with this prescription.
This collaborative effort represented a key milestone in improving access to essential therapy for improving the quality of life for HAE patients in Iran. Meanwhile, ongoing efforts continue to secure insurance coverage to expand and sustain medication availability in the future.

From Lina Keneciuse, HAE Latvia
After the conference, I had a conversation with one of our doctors, and she said that there is one more child diagnosed with HAE, so we are 14 patients now in Latvia. We also decided to be more strict with patients and try to force them to think more about themselves and their health, and make them send their stories to me by 01.12.2025, so I could include these stories in the letter to the Ministry of Health.

From HAE Mexico
Sweet Afternoon in Veracruz: A Taste of Culture and Hope

From Javier Santana, HAEi RPA for Central America and Caribbean, for HAE Panama
Official HAE Treatment Guideline Launched
We are delighted to share that in August, the Ministry of Health of Panama (MINSA) held a press conference to officially announce the launch of the ‘Official Treatment Guideline for Patients with Hereditary Angioedema (HAE).’
These HAE Guidelines were only possible thanks to the coordinated effort between the Minister of Health, Dr. Boyd Galindo; Dr. Johnny Cuevas, coordinator of the Rare and Uncommon Diseases Program at MINSA; renowned specialist Dr. Olga Barrera Melcina; HAE Panama, and our RPA, Javier Santana.
During the press conference, MINSA authorities emphasized that this measure is part of Panama’s commitment to recognizing and addressing rare diseases, ensuring that all patients have access to adequate, equitable, and evidence-based medical care.
In the words of Dr. Olga Barrera Melcina, “This guideline represents a crucial step forward for Panamanian patients with HAE, who now have a clear, adapted, and medically and scientifically supported protocol.”
For his part, Javier Santana, HAEi RPA, highlighted the value of joint work and Panama’s commitment as an example for the region in the fight for visibility and access to treatment for rare diseases. “Thanks to the commitment of Panama’s Minister of Health to his people, Panama is now positioning itself as a leader in Central America on the issue of Hereditary Angioedema, alongside Costa Rica. We are confident that it will soon reach the level of countries like Brazil, Colombia, Argentina, Mexico, and Chile in the Latin American region. We hope it becomes another center for training and research so that other countries in Central America can learn more about Hereditary Angioedema,” said Santana.
The new guideline establishes an updated clinical framework tailored to local needs, including protocols for early diagnosis, crisis treatment, preventive management, and comprehensive patient follow-up. Its implementation aims to significantly improve the quality of life of those living with HAE in Panama, as well as to strengthen the capacity of the healthcare system to address this condition effectively and in a timely manner.
In addition, we have seen new efforts from representatives of pharmaceutical companies to include their HAE medications in the government’s official procurement list.

From Michal Rutkowski, HAE Poland
A season of connection and networking: HAE Poland (also known as the Swelling Beautifully Association) at the 2025 Regional Conference EMEA and the final country conference in Poznań.
This year has been one of remarkable growth, visibility, and empowerment for the Polish HAE community. As part of its commitment to building a strong and inclusive patient network, the Swelling Beautifully Association not only brought together local communities across Poland but also made its mark on the international stage.
In October 2025, 23 representatives from the organization traveled to Rome, Italy to participate in the 2025 HAEi Regional Conference EMEA, a flagship event for the HAEi patient community from Europe, the Middle East, and Africa. With delegates from approximately 65 countries, the conference provided a unique platform for patients, caregivers, healthcare professionals, and advocates to share experiences, knowledge, and strategies for improving HAE care in the region.
For many of our members, this was not just a professional experience, but a deeply personal one. Standing shoulder to shoulder with other patients and caregivers, sharing best practices, and learning from global experts reinforced what we’ve long known: the power of community transcends borders.
Back at home, that same spirit of empowerment found its culmination in the city of Poznań, a week after the EMEA Conference, where we held the final local HAE event of 2025, and what a finale it was.
With over 110 participants from across western and northern Poland, the Poznań event brought together patients, families, and physicians for a truly meaningful day of education and connection. The conference welcomed distinguished guests and experts, including Dr Aldona Juchacz, Dr Małgorzata Sokołowska, and Dr Marcin Stobiecki, who brought deep clinical insight and a passion for patient-centered care. Their presentations covered both the medical and emotional aspects of managing HAE, including clinical research, pregnancy and children, latest advances in HAE therapies, and the current state of reimbursement for modern HAE treatment options in Poland.
However, what made this conference truly unforgettable were the stories shared by the patients themselves. From first-time speakers to long-time community members, these personal testimonies offered raw, heartfelt glimpses into life with HAE: the fear of uncertainty, the isolation, the unexpected strength found in others walking the same path, the power of patient advocacy, and significant changes with access to and reimbursement for on-demand and preventative therapies. Several attendees described the event as ‘life-changing’, not just because of what they learned, but because they felt seen, heard, and understood, sometimes for the very first time. Conversations flowed long after the final panel ended, with many patients exchanging contact information, planning local meetups, and expressing a renewed sense of hope and solidarity.
This year’s three local conferences held an even deeper meaning, as 2025 marks the 20th anniversary of HAE Poland’s registration and the 22nd anniversary of starting HAE patient advocacy on Polish soil. Each meeting became not only an opportunity for learning and support but also a heartfelt celebration of over two decades of community building, advocacy, and resilience. Looking back on twenty-plus years of dedication to the HAE community, every shared story, every handshake, and every new connection felt like a living tribute to how far we have come together since Prof. Krystyna Obtułowicz (the godmother of ‘Polish HAE’) diagnosed the first Polish HAE patient back in February 1981.
By choosing to bring local conferences directly to the regions, the Swelling Beautifully Association continues to break down the barriers that so often define rare disease care: distance, isolation, and lack of access. The Poznań conference wasn’t just the last stop on a tour; it was a celebration of everything we’ve built together and a reminder of the road ahead. It wouldn’t be possible to organize a single event without the dedicated team of extraordinary HAE advocates and human beings: Dominika, Estera, Sonia, Jakub, Piotr, and Sebastian. Their passion, expertise, knowledge, perseverance, and never-give-up attitude are the foundations of HAE Poland’s mission.

The year 2025 is an important milestone for HAE patients in Saudi Arabia, as we launched our official website with the support of the HAEi team. Through this platform, we were able to connect with some patients and their caregivers and provide support and guidance.
In addition, we participated in the 2025 HAEi Regional Conference EMEA in Rome. Our representative Mona Alasker was one of the speakers at the panel discussion “Stigma and Cultural Differences”.
Looking ahead, we are excited about the upcoming patient meeting in Riyadh, which will be attended by the regional HAEi representative, Michal Rutkowski.

From Teja Iskra Cigljar, HAE Slovenia
I would like to share with you some of the activities carried out by the HAE Patients’ Association Slovenia in our country this year. At the beginning of February, we were invited to a press conference, which is organized every year on the occasion of Rare Disease Day by the Association for Rare Diseases of Slovenia and is intended for healthcare professionals and the media. The live broadcast is available through the Slovenian Press Agency. This year’s theme was Women with Rare Diseases, and there we presented our booklet, Women with HAE. It was previously translated into Slovenian and printed. Since we aroused interest among patients with two different rare diseases, we were interviewed for Jana magazine a few days later. It is an established family magazine that later published an honest article about two patients with rare diseases and their fight against the disease. At the end of February, we attended the 11th national conference on the occasion of Rare Disease Day, organized by the Association for Rare Diseases of Slovenia and the Ministry of Health of the Republic of Slovenia. The event took place in Brdo pri Kranju.
On May 17th, we had the first meeting of HAE patients in Slovenia under the auspices of HAE Slovenia. There weren’t many of us, but it was just enough to start. We opened some interesting ones and tried to solve problems as they arose. Since we have a small country with only two million inhabitants, there aren’t many HAE patients. According to the information so far, there are about 30 of us. Therefore, we can connect with some of them personally and thus solve some of the problems that HAE patients face.
We also recently attended a meeting with patients in the neighboring country of Croatia, where they have an annual meeting of children with HAE. It was very educational and enjoyable, as always when we meet friends from neighboring countries.
A few days ago, we also returned from the 2025 HAEi Regional Conference EMEA in Rome. Such meetings always enrich us, both with new knowledge and new acquaintances, as well as with news in the field of HAE treatment. And they empower us.
We are also preparing a video, intended for the education of nurses, about the work of HAE Slovenia.
We have no shortage of work, challenges, and ideas, so we are bravely moving forward to new victories.

AEDAF Participates in the 2025 HAEi Regional Conference EMEA (Rome)
The Spanish Association of Familial Angioedema Patients (AEDAF) had a large delegation at the 2025 HAEi Regional Conference EMEA, held in Rome, Italy, from October 10th to 12th. With approximately 30 members in attendance, including members from different communities (Madrid, Catalonia, Andalusia, Castile and León, the Basque Country, Navarre, La Rioja, and Aragon, among others) and medical professionals from across Spain, it was one of the largest gatherings.
As always, this conference provided an opportunity to personally observe the situation of HAE patient associations in the participating countries, the specialized medical professionals treating them, their access to treatments and medications, and how living in different countries affects these aspects of their lives.
The situation varies so much depending on the country of birth that it almost seems like different worlds and different diseases. This makes you realize that we must continue fighting to ensure everyone has access to, first and foremost, an accurate diagnosis, since confirming it can be a difficult task, and secondly, to the appropriate medication to treat the disease and achieve a normal quality of life, as far as possible. Although it seems like an impossible task, this is what associations work towards every day, and with the help of HAEi, we are making progress step by step towards achieving this goal, which is complicated by the different and varied situations in each country.
Attending and participating in the 2025 HAEi Regional Conference EMEA in Rome was a true pleasure and provided invaluable access to important information to continue raising awareness and trying to improve the quality of life for people affected by HAE in Spain.


From Ernst Greber, HAE Switzerland:
Llama Trek
On Saturday, August 30, 2025, we organized a llama trek. At 2:00 p.m., we gathered at the farm of our former HAE President, Paula Hunkeler. Paula welcomed 10 children and 10 adults.
She keeps approximately 32 llamas and alpacas there. There, she gave us an introduction to the differences between these two animals.
Afterward, we set off on a 2.5-hour hike through the forests of Matzendorf. We were offered a small aperitif along the way.
Unfortunately, the weather wasn’t on our side during the hike. At first, it was sunny, but after a short while, the weather changed, and it poured with rain, and we got wet despite our rain gear.
After our hike, we enjoyed a wonderful dinner. She also told us what all the wool can be made from.

Rome, here we come
We were represented by a large group at this year’s EMEA meeting from October 9th to 12th, 2025. We would like to praise the excellent organization. The conference venue was difficult to reach for those who arrived a day early and wanted to visit the city of Rome.
We were able to learn about some new developments and were surprised at how some countries have virtually no access to medications. The transfer to the airport was well organized.


From Marijk Beekman-Kortekaas, President, HAE the Netherlands
Dear HAE friends
It’s hard to believe we’re already in the fourth quarter of the year! Time seems to have flown by. This past period has been filled with so many great moments. We’d love to share a few highlights with you.
Dutch Delegation at the 2025 HAEi Regional Conference EMEA in Rome
This October, ten enthusiastic representatives from the Netherlands took part in the 2025 HAEi Regional Conference EMEA in Rome. Our delegation included patients, caregivers, and board members, each contributing their unique voice to the conversations.
A special highlight for us was the participation of four young people in the Youngsters Track. Noa has been working very hard to create a Dutch Youngsters community, and we are very happy to see that our youngsters are so enthusiastic about it. They had an absolutely fantastic time in Rome, making new friends from across the region, learning more about HAE, and sharing their experiences about what it means to live with HAE in the Netherlands. We’re especially proud that Noa was invited to speak during the panel discussion ‘Voices of Change: Small Steps, Big Impact’, where she shared her perspective with confidence and heart.
Of course, we’re not only proud of Noa; we’re incredibly proud of everyone who stepped onto the stage to share their story or contribute to a panel discussion. We felt very inspired by all these different stories. We believe that storytelling and shared experience are powerful tools for connection, understanding, and change. The conference was also a valuable opportunity to connect with colleagues from other countries, exchange ideas, and strengthen our shared commitment to improving the lives of people living with HAE.
We returned home with renewed motivation, practical tools, and a deeper sense of community. Thank you, HAEi, for bringing the community together. We’re already looking forward to the next conference!
Celebrating Noa’s LEAP Graduation and her next steps
We’re incredibly proud to share that Noa has successfully completed the HAEi LEAP program. LEAP has helped shape Noa into an even stronger patient advocate, equipping her not only with knowledge and confidence, but also with practical tools that she is already putting to use in supporting HAE the Netherlands.
The LEAP program has empowered Noa to take initiative and lead with purpose. She’s currently working on an exciting project: the creation of a youngsters community in the Netherlands. Her goal is to build a safe, supportive space where young people can connect, share experiences, and grow together. We’re thrilled to see her vision take shape and are confident it will have a lasting impact.
We encourage our fellow patient organizations to consider nominating a young person for the LEAP program. Investing in the next generation of advocates is one of the most powerful ways we can strengthen our community and shape the future of HAE care.
Dr. Mats de Lange wins Young Investigator Award
We’re thrilled to share that Dr. Mats de Lange has received the prestigious Young Investigator Award at this year’s 2025 HAEi Regional Conference EMEA in Rome. Following in the footsteps of Dr. Remy Petersen, Mats is the second Dutch researcher to bring this honor home, and we couldn’t be more proud.
Mats is known not only for his scientific dedication and sharp mind, but also for his kindness and genuine commitment to the HAE community. Despite a demanding schedule, he’s offering support, insight, and collaboration with HAE the Netherlands whenever possible.
This award is a well-deserved recognition of his work and his impact. We’re excited to see where his research will lead next.
November 22: Information Day in Breukelen
We’re already looking forward to it: on Saturday, November 22, 2025, we’re hosting our Dutch annual Information Day, once again at the familiar Hotel Van der Valk in Breukelen.
The full program is still taking shape, but we can already share an exciting new feature: this year marks the first-ever youngsters program. With it, we’re creating a space where younger participants can connect, feel seen, and join in their own way.
We warmly invite everyone in the Netherlands living with HAE and their families to join us. It’s a wonderful opportunity to connect with others who live with HAE, share experiences, and feel part of a supportive community. It’s also a great chance to get up to date on the latest developments, treatments, and initiatives in the HAE world. Whether you’ve been involved for years or are newly diagnosed, we’d love to welcome you.

From Krizzia Lavone Ramos Alferez, HAE Philippines
On September 8, 2025, the HAE symposium was conducted in Manila, Philippines, with participants including Anthony Castaldo—HAEi CEO and Advocacy Lead, Developing Southeast Asia; Krizzia Lavone Alferez—national contact; Dr. Philip Li; Dr. Jovilia Abong (HAE specialist in the Philippines); and BioCryst’s Dr. Dan Petroni and Lauren Mills. BioCryst is a pharmaceutical company with a pill that helps prevent HAE attacks.
The symposium was part of the annual convention of the Philippine Society of Allergy, Asthma, and Immunology (PSAAI) in cooperation with Dr. Joanne Mallillin and Dr. Kay Salvador-Tayag. 550 physicians from all across the Philippines were present.
Dr. Philip Li spoke on “Alliances and Advancements for Hereditary Angioedema in the Asia Pacific.” He also shared patient stories from Hong Kong and highlighted successful diagnostic and treatment progress.
Dr. Petroni chaired the symposium discussion, which covered the present situation and experiences of people with HAE in the Philippines. Numerous questions from attendees regarding the topic were raised. HAE Philippines is advocating for all Filipino patients and working to increase general awareness of the disease and win access to modern HAE medicines.

From HAE UK
It’s been another busy few months for HAE UK, filled with activity, collaboration, and progress for our patient community.
We’ve been working closely with several pharmaceutical companies on a range of patient surveys, making sure patient voices are heard as new treatments and research develop. The feedback continues to shape how HAE care evolves in the UK – so thank you to everyone who has taken part!
In September, HAE UK was proud to attend the 2025 HAEi Regional Conference EMEA in Rome, with just under 50 of our members representing the UK. It was fantastic to connect with patients, clinicians, and organizations from across Europe, the Middle East, and Africa, sharing experiences and learning about the latest developments in HAE care.
Back at home, we’re celebrating the UK approval of garadacimab, a new preventive treatment option for people living with HAE. This marks a big step forward in helping reduce the frequency of attacks and improving HAE patients’ quality of life – and there are even more new therapies on the horizon, which is really exciting.
As always, HAE UK remains dedicated to supporting everyone affected by HAE and ensuring access to the best possible care across the UK.

Natalia Formaniuk, President, HAE Ukraine
This fall, Ukraine participated in the 2025 HAEi Regional Conference EMEA in Rome, ‘Embracing Opportunities’.
On October 10–12, the 2025 HAEi Regional Conference EMEA was held in Rome, bringing together representatives of patient organizations, leading doctors, scientists, and industry representatives from around the world. For the Ukrainian community, this event was an opportunity to present the results of our joint work and join the global dialogue on improving the quality of life of patients with HAE.
Representatives of the patient and medical community participated in the conference from the Ukrainian HAE Association. HAE specialists Lyudmila Zabrodska, Anastasia Bondarenko, and Khrystyna Yakimovich-Lishchuk presented a poster with the results of an interdisciplinary study on the genetic characteristics of HAE in Ukraine. Professor Anastasia Bondarenko gave an oral presentation, adequately answering the questions of colleagues from different countries. We are sincerely proud of our doctors, who, with their work, strengthen the position of Ukrainian medicine at the international level. Their contribution, together with the international team, to improving diagnostics, treatment, and support for patients with HAE is invaluable, because behind every scientific report there is a human life, alleviated suffering, and restored hope.
The days of the conference were full of speeches by the president of HAEi, management, regional advocates, and patients who shared their stories and experiences on using opportunities. Our team gained invaluable experience by getting acquainted with the latest methods of treatment and prevention. In the question session, we heard answers from specialists to frequently asked questions that cause discussions and disputes among our patients as well.
In this warm atmosphere, we felt that the HAE community is not just an organization, but a big family, united by a common goal – to change the lives of people with HAE for the better.
I would like to highlight once again the statement that is the motto for people with HAE – ‘Never give up!’
This is a short but powerful phrase that reminds us: every opportunity is a step forward. And it is important not to stop, even when the path is difficult.

From Jess Myers, Communications and Advocacy Manager, US HAEA
Visits with Elected Officials During HAEA Virtual Capitol Hill DayThis year’s HAEA Virtual Capitol Hill Campaign once again showcased the incredible dedication and passion of our grassroots advocates – a group of volunteers who donate their time to be a part of the HAEA public policy advocacy program. These HAEA friends met virtually with their elected officials to share personal stories and advocate for policies that protect: Full access to HAE therapies, financial support for treatment, and funding for research to address the remaining scientific mysteries surrounding HAE.
Grassroots advocates from 33 states held over 60 meetings with Members of Congress and their staff, raising awareness about HAE and emphasizing the importance of continued support for our community. Each conversation helped strengthen relationships with key decision-makers and advance our mission to ensure that everyone affected by HAE receives the care they deserve.
Thank you to all the HAEA grassroots advocates who shared their voices and made a difference. Your commitment continues to drive meaningful legislative and regulatory policies that benefit people with HAE and their families.
Shining a Spotlight on the Next Generation of HAEA LeadersEvery October, we celebrate Youth Advocacy Month by showcasing the stories and activities of the youth advocates in our community. This year, we are excited to recognize over 35 young leaders who were nominated to the Youth Advocacy Achievement League, a program that honors young advocates who have stepped up in powerful ways that include:
- Raising awareness about HAE,
- Championing legislative change,
- Supporting their peers, and
- Strengthening their local communities.
We’ll be sharing Youth Advocacy Achievement League stories across social media in October. We invite you to follow along, celebrate their achievements, and join us in honoring the next generation of HAEA leaders who are paving the way toward a brighter future. Find us on Instagram at @HAEAYouth.
New Resource for Young Adults: Insurance Frequently Asked QuestionsNavigating the American insurance system can be confusing, especially while managing HAE. That’s why youth leader, Isabelle B., worked with the US HAEA to create the Young Adult Insurance Frequently Asked Questions document – a helpful guide to answer common questions about coverage options and enrollment.
If you’re based in the United States and aging out of a parent’s plan, exploring the marketplace, or choosing between employer options, this resource can be used to support you every step of the way.
Check out the new Young Adult Insurance FAQ here: Young Adult Insurance FAQ
Bringing the HAEA Community Together Through Our Community Connection EventsThe HAEA Community Connection Events provide people living with HAE, along with their loved ones and caregivers, the opportunity to meet in a supportive and understanding environment. Attendees share their personal stories, exchange helpful insights, and gain valuable information about the many programs and resources available through the HAEA.
Earlier this year, the HAEA hosted events engaging with more than 350 people with HAE and their families in cities all over the United States, including: Fairfax, VA, Orlando, FL, Detroit, MI, Birmingham, AL, Chicago, IL, and Northern California. This fall, the HAEA will continue these important gatherings with Community Connection events in Middlefield, Connecticut, and San Juan, Puerto Rico.

Lanadelumab’s impact on hereditary angioedema control and quality of life across disease activity subgroups: Real-world evidence
Andrea Zanichelli, et al
The authors used real-world data to examine the longer-term effectiveness of lanadelumab in individuals with HAE who had varying attack rates before starting treatment (baseline disease activity rate). The authors found that in patients treated with lanadelumab, the attack rates were low, and patients experienced improvements in health-related quality of life and disease control, regardless of their baseline disease activity. Overall, the authors feel these findings support long-term prophylaxis with lanadelumab across disease activity levels.

Insights from the first 820 patients from the Brazilian multicenter registry of hereditary angioedema: The key role of genetic testing and targeted therapies
Mariana PL Ferriani, et al
The authors aimed to identify knowledge gaps among healthcare professionals that may be hindering patient care in Brazil. In conclusion, they found that Brazilian patients with HAE share common aspects with global patients, including predominance in women, and HAE-C1INH as the most common subtype. Available genetic testing enabled the identification of a notable proportion of HAE-FXII (19.4% of patients). Despite recent advances, access to first-line therapies for long-term prophylaxis of HAE attacks remains limited.

Real-world treatment patterns and burden-of-disease of sub-optimally controlled hereditary angioedema
Henriette Farkas, et al
The authors investigated the impact of poorly controlled HAE on the quality of life of patients. They found that, on average, patients with uncontrolled HAE had just under 10 attacks (9.9) per year. They found that the quality of life worsened as attack rates increased. They concluded that sub-optimal disease control in HAE is associated with the use of only on-demand therapy. Poorly controlled HAE has a serious burden on the lives of patients, especially in those with frequent attacks and in women.

First and only RNA-targeted prophylactic treatment for HAE approved in the US
A new medicine for HAE, called Dawnzera (donidalorsen) has been approved by the regulatory authorities in the USA, and can begin to be prescribed to people with HAE in the coming days.
The US Food and Drug Administration (FDA) approved donidalorsen to prevent attacks of HAE in adults and pediatric patients 12 years of age and older. Donidalorsen reduces the production of prekallikrein by turning off certain genetic messages in the body. This stops the body from overproducing bradykinin, preventing HAE attacks.
Donidalorsen 80mg is self-administered via subcutaneous autoinjector once every four (Q4W) or eight weeks (Q8W).
Brett P Monia PhD, Chief Executive Officer, Ionis, said: “Dawnzera represents a significant advance for people living with HAE who need improved treatment options. With strong and durable efficacy, convenient administration and the longest dosing option available, we believe Dawnzera will be the prophylactic treatment of choice for many people living with HAE. At Ionis, we are dedicated to turning groundbreaking science into life-changing medicines. To the patients, families, advocacy partners and investigators who helped make this moment a reality, we express our deepest gratitude.”
Anthony J Castaldo, CEO & Chairman of the Board, US Hereditary Angioedema Association (HAEA) and Hereditary Angioedema International (HAEi), said: “As the first FDA-approved RNA-targeted therapy for HAE, Dawnzera represents a welcome advance in therapeutic options for preventing attacks. Today’s approval gives people living with HAE and their physicians another important choice for aligning treatment with individual needs.”
Marc Riedl MD MS, Clinical Director, US HAEA Angioedema Center; University of California, San Diego; OASIS-HAE and OASISplus trial Investigator, said: “People living with HAE manage this condition for all their lives, and many continue to face unpredictable, painful and dangerous breakthrough attacks even with current treatments. Durable efficacy is essential in maintaining long-term disease control. Dawnzera is positioned to help meet patient needs, providing substantial and sustained reduction of HAE attacks, continued improvement over time and reduced burden of treatment.”

Updates provided on sebetralstat, an HAE medicine currently being used by people, by manufacturer
[Sebetralstat is also often referred to by its brand name, Ekterly]
A series of updates on sebetralstat, which has recently been approved for the treatment of HAE, were provided by the pharmaceutical company KalVista. The key updates shared were:
- FDA approval and US launch of sebetralstat, a novel plasma kallikrein inhibitor for the treatment of acute attacks of hereditary angioedema (HAE) in adult and pediatric patients aged 12 years and older, took place on 7 July 2025
- In July 2025, the Medicines and Healthcare products Regulatory Agency (MHRA) of the United Kingdom (UK) granted marketing authorization for sebetralstat. Sebetralstat also met the requirements of the MHRA Orphan Designation criteria and will be added to the Orphan Register held by the MHRA, allowing it to benefit from up to 10 years of market exclusivity.
- Also in July 2025, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion recommending marketing authorization for sebetralstat. The European Commission (EC) final decision is expected in October 2025.
- The Committee for Orphan Medicinal Products (COMP) of the EMA confirmed maintenance of orphan designation for sebetralstat. This designation secures important regulatory and financial benefits, including 10 years of EU market exclusivity, making sebetralstat one of only two HAE medicines to retain orphan status.
Ben Palleiko, CEO of KalVista, said: “This quarter marked a defining moment in the history of KalVista with the FDA approval of Ekterly — the first and only oral on-demand treatment for HAE. Approval and launch on the same day propelled us immediately into our next chapter and the response has been extraordinary. This early demand has exceeded our expectations, validating both the urgent unmet need that Ekterly addresses and its potential to redefine management of HAE.”

Data on burden of HAE, and effectiveness of sebetralstat in children and adults unveiled at 2025 ACAAI Annual Scientific Meeting
The latest data on a new medicine for HAE, sebetralstat (brand name Ekterly), was presented at the American College of Allergy, Asthma & Immunology (ACAAI) 2025 Annual Scientific Meeting, Orlando, USA, 6-10 November 2025.
The following is a summary of some key findings:
Sebetralstat for on-demand treatment of HAE attacks in patients switching from injectable on-demand treatments
- For 1,089 attacks treated with sebetralstat by patients in KONFIDENT-S who had switched from injectable on-demand treatments (icatibant, pdC1INH, rhC1INH), median treatment satisfaction score was 2 (very satisfied) on a 7-point Likert scale ranging from –3 (extremely dissatisfied) to 3 (extremely satisfied)
- Overall, 84% of attacks treated with sebetralstat were rated by participants as satisfied, very satisfied, or extremely satisfied, with the vast majority being very or extremely satisfied
Sebetralstat for on-demand treatment of HAE in pediatric (2-11 years old) patients (KONFIDENT-KID)
- Among 65 attacks treated in 26 children receiving weight-based dosing of sebetralstat in a proprietary oral disintegrating tablet (ODT) formulation as of 6 June 2025:
- Participants treated a mean of 0.8 attacks per month
- Caregivers or patients administered treatment in a median of 30 minutes
- Median time to symptom relief (150 mg cohort) was 1.5 hours
- Sebetralstat was well tolerated with no serious or treatment-related adverse events, and no reports of difficulty swallowing
Ben Palleiko, Chief Executive Officer of KalVista, said: “Hereditary angioedema affects families across generations, and the possibility of an oral on-demand option for pediatrics is profoundly meaningful—not only for patients, but for their caregivers as well. In KONFIDENT-KID, children with HAE experienced a higher frequency of attacks than previously appreciated. The availability of sebetralstat could help ensure these attacks are treated earlier and more consistently, ultimately improving care for pediatric patients and their families. The data presented at ACAAI collectively underscore the transformative potential of sebetralstat, empowering patients of all ages to treat attacks early, effectively, and without injections.”

Data on long-term HAE disease control with donidalorsen unveiled at 2025 ACAAI Annual Scientific Meeting
The latest data on a new medicine for HAE, donidalorsen (brand name Dawnzera), was revealed at the American College of Allergy, Asthma & Immunology (ACAAI) 2025 Annual Scientific Meeting, Orlando, USA, 6-10 November 2025.
The following is a summary of some key findings:
- Donidalorsen showed durable efficacy, demonstrating 94% overall mean HAE attack rate reduction at one year in an open-label extension study
- Patients in a study looking at treatment switching, achieved a 68% improvement in mean HAE attack rate compared to prior prophylactic therapy one year after switching to donidalorsen
- Long-term efficacy and safety maintained up to four years in the Phase 2 open-label extension study
Donidalorsen was recently approved by the US Food and Drug Administration for prophylaxis to prevent attacks of HAE in adult and pediatric patients 12 years of age and older.
Kenneth Newman MD, Senior Vice President, Clinical Development at Ionis, said: “These new long-term data support our belief that donidalorsen, which is now available to people living with HAE in the US, is well-positioned to transform the treatment paradigm for HAE. The latest results from across our clinical studies support the strong and durable efficacy and safety profile of donidalorsen. Presentations at the congress offer patients and physicians valuable insights to support informed treatment decisions, including when transitioning to donidalorsen from a previous prophylactic therapy.”

Data on burden of HAE, and effectiveness of berotralstat, in children unveiled at 2025 ACAAI Annual Scientific Meeting
A series of scientific presentations demonstrating the impact of HAE on the lives of pediatric patients and caregivers, and the effectiveness of berotralstat (also referred to by its brand name, Orladeyo), have been presented at the Annual Scientific Meeting of the American College of Allergy, Asthma & Immunology (ACAAI) Orlando, USA, 6-10 November 2025.
Here’s a summary of some of the key findings of the research:
Impact of HAE on pediatric patients and caregivers
- Adolescents and caregivers report that HAE negatively impacts young patients’ mental health, communication with others, and participation in school, sports, and social activities.
- 90% of HCPs reported that HAE attacks distress caregivers and patients, disrupt caregiver and patient daily routines, and negatively impact patients’ quality of life.
- Caregivers reported that attacks occur about every 3 months and rated HAE as moderately severe (mean of 4.0 on a scale of 1-7).
- Over three-quarters of adolescents (11/14) and nearly half of caregivers (11/23) reported going to the ED or hospital at least once before age 12. Visits ranged from a few hours to a few days in length.
- Most adolescents and caregivers have experienced negative ED/hospital experiences, including treatment delays, medication unavailability, challenges with medication administration, HCPs unfamiliar with HAE, and heightened stress due to the ED/hospital environment
Effectiveness of berotralstat as a treatment for young people with HAE (2-11 years old)
- Berotralstat demonstrated early and sustained attack rate reduction, with 65.5% of patients attack-free at month 1 and 70.4% of patients attack-free at month 12. Nearly all (93.1%) patients completed ≥48 weeks of treatment.
- Berotralstat was safe and well tolerated, with no new safety signals identified. The most commonly reported treatment-emergent adverse event (TEAE) was nasopharyngitis (the common cold).
Dr Donald S. Fong, Chief Medical Officer of BioCryst, said: “Our psychosocial data elucidate that HAE attacks typically begin well before puberty and can have a profoundly negative impact on the mental health and quality of life of both children and their caregivers. Currently there are only injectable treatments approved for prevention of attacks in patients under 12. Berotralstat would be the first and only targeted oral prophylactic therapy for patients with HAE aged 2 to less than 12 years, if approved.”
A New Drug Application (NDA) for an oral granule formulation of berotralstat to prevent HAE attacks in pediatric patients with HAE aged 2 to <12 years is currently under review with the US Food and Drug Administration (FDA), with a target action date of December 12, 2025.

Data on safety and effectiveness of potential HAE treatment, deucrictibant, presented at 2025 ACAAI Annual Scientific Meeting
The latest data on a potential new medicine for HAE, deucrictibant, was presented at the American College of Allergy, Asthma & Immunology (ACAAI) 2025 Annual Scientific Meeting which took place in Orlando, Florida from 6-10 November 2025.
The following is a summary of some key findings:
- Open-label prophylaxis data supporting the long-term safety profile and sustained benefits of deucrictibant, as well as clinical validation data of a kinin biomarker assay were highlighted in two oral presentations
- Final data from participants in the open-label portion of the CHAPTER-1 study provide further evidence of a well-tolerated safety profile for up to approximately 34 months and an average of 92.4% attack reduction from study baseline with deucrictibant treatment
- Six additional posters detail the effectiveness, safety, and health-related quality of life outcomes from various clinical studies
Berndt Modig, Chief Executive Officer of Pharvaris, said: “We are proud about the recognition of the scientific community of the importance attributed to the late-stage confirmatory clinical data of deucrictibant and the associated biomarker work as oral presentations at the American College for Allergy, Asthma and Immunology annual conference. Beyond the scientific merit we are looking forward to the potential impact deucrictibant could have on the lives of people living with bradykinin-mediated angioedema.”
In an additional media communication, Pharvaris provided a series of operational updates. The key summaries were:
- Data from a pivotal Phase 3 study of deucrictibant for the on-demand treatment of HAE attacks is expected in the fourth quarter of 2025
- Data from CHAPTER-3, a pivotal Phase 3 study of deucrictibant for prophylaxis of HAE attacks, is anticipated in 2H2026
- CREAATE, a pivotal Phase 3 study of deucrictibant for the prophylactic and on-demand treatment of AAE-C1INH attacks
Berndt Modig, Chief Executive Officer of Pharvaris, said: “We remain on track to report data from the pivotal Phase 3 trial, RAPIDe-3, in the fourth quarter of 2025. The achievement of this data readout, combined with the anticipated readout of CHAPTER-3 in the second half of next year, and the future outcome of the recently initiated CREAATE study, demonstrate our continued execution and commitment to develop new and innovative therapies for people with bradykinin-mediated diseases.”
