Which advice would you give to someone who has just been diagnosed with Hereditary Hemorrhagic Telangiectasia?

A diagnosis of Hereditary Hemorrhagic Telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome, can feel overwhelming, but it is a manageable condition when treated by specialized centers that focus on screening for internal arteriovenous malformations. The most critical step is to transition from general care to a multidisciplinary HHT Center of Excellence, where clinicians can proactively monitor for complications like pulmonary or cerebral AVMs before they become symptomatic.

What is the most important advice for a new Hereditary Hemorrhagic Telangiectasia diagnosis?

The most vital action after receiving a diagnosis of Hereditary Hemorrhagic Telangiectasia is to establish care with a dedicated HHT Center of Excellence. Because HHT is a systemic vascular disorder, it requires a team approach involving pulmonologists, neurologists, hematologists, and interventional radiologists who understand the unique risks of vascular malformations. Do not attempt to manage this condition alone; early screening for asymptomatic arteriovenous malformations (AVMs) in the lungs, liver, and brain is the gold standard for preventing life-altering emergencies.

How do I build an effective care team and manage daily life?

Living with Hereditary Hemorrhagic Telangiectasia often involves managing chronic iron-deficiency anemia due to recurrent epistaxis (nosebleeds) or gastrointestinal bleeding. Your team should prioritize iron replacement therapy and, when necessary, blood transfusions. To manage daily life and energy levels, keep a detailed symptom journal to track the frequency and severity of your nosebleeds. Patients often find that humidifiers, saline nasal sprays, and avoiding specific blood-thinning medications (after consulting your physician) significantly improve quality of life.

Why is community support essential for Hereditary Hemorrhagic Telangiectasia patients?

Connecting with others who have Hereditary Hemorrhagic Telangiectasia can alleviate the isolation that often accompanies a rare disease diagnosis. At DiseaseMaps.org, 141 members have shared their experiences, providing a wealth of peer-to-peer knowledge about navigating insurance, managing work-life balance, and coping with the emotional impact of a genetic condition. Engaging with the community also helps you stay informed about the latest clinical trials and research breakthroughs.

What are the critical steps for family members?

Since Hereditary Hemorrhagic Telangiectasia is an autosomal dominant genetic disorder, each child of an affected parent has a 50% chance of inheriting the condition. It is imperative to discuss genetic counseling with your family. Early diagnosis in relatives is life-saving, as it allows for preventative screening protocols to be implemented long before serious symptoms arise.

How can I stay informed and find resources?

Navigating the healthcare system for Hereditary Hemorrhagic Telangiectasia requires persistence. Utilize the following resources to stay current and supported:

• Clinical Trials: Visit ClinicalTrials.gov to monitor ongoing studies regarding drug therapies for HHT-related bleeding.


• Expert Centers: Use the Cure HHT foundation’s center locator to find the nearest multidisciplinary team.


• Financial Aid: Explore programs like the Patient Advocate Foundation if you face barriers to accessing specialized care or medication.


• Genetic Counseling: Consult with a genetic counselor to understand the specific mutation in your family and the implications for future generations.

Next steps

• Schedule an appointment at an HHT Center of Excellence for a baseline screening of your lungs and brain.


• Join the Hereditary Hemorrhagic Telangiectasia community at DiseaseMaps.org to connect with others.


• Create a "medical passport" detailing your specific AVM risks and current medications to share with emergency responders.


• Discuss genetic testing options with your physician to provide clarity for your biological relatives.
