Is Osler-Weber-Rendu Syndrome Fatal? Outlook and More
Most people with this condition live a full, typical life, but it can be life threatening if a blood vessel ruptures in an internal organ and bleeds uncontrollably.
Osler-Weber-Rendu syndrome, which is also called hereditary hemorrhagic telangiectasia (HHT), is a rare genetic disorder that causes atypical blood vessels to form in your skin and mucous membranes, as well as in vital organs such as your lungs and brain.
It affects only about 1 in every 5,000 people in the world, but the actual number may be higher because some people have few or no symptoms and might not know they have the condition. It can affect people of all genders and ethnicities. Recurrent nosebleeds are often the first symptom.
Here we explain how Osler-Weber-Rendu syndrome can be life threatening and the overall outlook for living with it.
Is Osler-Weber-Rendu syndrome (HHT) life threatening?
Osler-Weber-Rendu syndrome can be life threatening if a blood vessel ruptures in an internal organ and bleeds uncontrollably. However, death from this condition is more likely to occur if you don’t know you have it and are not receiving regular screenings and treatment.
When monitored and treated by a doctor, Osler-Weber-Rendu syndrome doesn’t affect life expectancy for most people.
Often, the first symptom of Osler-Weber-Rendu syndrome is a persistent nosebleed. Nosebleeds happen because small, fragile blood vessels (telangiectases) form in the membranes that line the inside of your nose. Though this requires treatment, it’s not likely to be life threatening.
Most other possible complications of this condition are also not life threatening, but they can vary in severity. They may include:
On the other hand, bleeding within your brain, lungs, and liver can be life threatening because it may happen suddenly.
What causes death with Osler-Weber-Rendu syndrome (HHT)?
If you have Osler-Weber-Rendu syndrome, some of your blood vessels lack capillaries. The capillaries help lower the pressure of your blood before it reaches your veins.
Without these capillaries, there’s nothing to lower the pressure of the blood before it enters your veins. As a result, your veins become strained and fragile and are prone to rupture (burst). These atypical veins are called arteriovenous malformations (AVMs).
Rupture of large AVMs can lead to extensive bleeding (hemorrhage), which can cause a stroke, a brain abscess, sepsis, or heart failure. Death can occur if a hemorrhage happens in any of the following areas:
What is the mortality rate for Osler-Weber-Rendu syndrome (HHT)?
Because Osler-Weber-Rendu syndrome is so rare and its presentation can vary widely from person to person, the mortality rate isn’t easy to estimate.
Without proper treatment, Osler-Weber-Rendu syndrome can reduce life expectancy because of the risk of severe bleeding from ruptured AVMs.
A 2021 study conducted in Denmark found that chronic gastrointestinal bleeding, anemia, and symptomatic liver AVMs were associated with higher mortality.
What is the outlook for Osler-Weber-Rendu syndrome?
Most people with Osler-Weber-Rendu syndrome will live a typical, healthy life with no change to their life expectancy.
A 2020 study found no difference in survival between people with Osler-Weber-Rendu syndrome who were periodically screened for AVMs in vital organs and a control group who did not have the condition.
The HHT group had a life expectancy of 75.9 years, while the control group had a life expectancy of 79.3 years. While the life expectancy was higher in the control group, the difference wasn’t statistically significant to the researchers.
The outlook is less favorable in people who don’t receive screening and treatment. For this reason, current international HHT guidelines strongly recommend screening for AVMs in the lungs and brain.
Your doctor can monitor the ongoing symptoms of this condition through regular checkups. Brain and lung AVMs are treated with surgical procedures. If you have an AVM in your liver, you might need a liver transplant.
What is Osler-Weber-Rendu Syndrome?
Osler-Weber-Rendu Syndrome, also known as Hereditary Hemorrhagic Telangiectasia (HHT), is a genetic disorder that affects blood vessels. It leads to abnormal blood vessel formation, particularly in the skin, mucous membranes, and organs such as the liver and lungs. People with this condition often experience frequent nosebleeds and may have red or purple spots on the skin, known as telangiectasias.
Is Osler-Weber-Rendu Syndrome fatal?
While the syndrome itself is not inherently fatal, it can lead to serious complications that may be life-threatening. These complications include severe bleeding, anemia, strokes, and complications due to blood vessel malformations in organs like the brain, lungs, and liver. With appropriate management and monitoring, many individuals with the condition can lead relatively normal lives.
What are the symptoms of Osler-Weber-Rendu Syndrome?
Common symptoms include frequent nosebleeds, red or purple spots on the skin or mucous membranes, called telangiectasias, and bleeding in different organs. Some individuals may also experience shortness of breath, fatigue due to anemia, and gastrointestinal bleeding. Symptoms vary widely among individuals, even within the same family.
How is Osler-Weber-Rendu Syndrome diagnosed?
Diagnosis is typically based on clinical criteria, including a pattern of nosebleeds, family history, and the presence of telangiectasias. Genetic testing can confirm the diagnosis by identifying mutations in specific genes known to cause the syndrome. Imaging studies may also be used to identify blood vessel malformations in organs.
What treatments are available for Osler-Weber-Rendu Syndrome?
Treatment focuses on managing symptoms and preventing complications. This may include controlling nosebleeds through nasal sprays or cauterization, iron supplementation or blood transfusions for anemia, and medical or surgical interventions for blood vessel malformations in organs. Regular monitoring by a healthcare team familiar with the syndrome is essential for effective management.
What is the outlook for individuals with Osler-Weber-Rendu Syndrome?
The outlook varies depending on the severity of the symptoms and the organs involved. With regular medical care and management of symptoms, many individuals can lead healthy lives. Early diagnosis and intervention can help prevent serious complications, improving the long-term outlook for those with the syndrome.
How is Osler-Weber-Rendu Syndrome inherited?
Osler-Weber-Rendu Syndrome is an autosomal dominant genetic disorder, meaning that an affected individual has a 50% chance of passing the condition on to their children. The syndrome is caused by mutations in specific genes that affect blood vessel development.
Takeaway
Osler-Weber-Rendu syndrome, which is also known as hereditary hemorrhagic telangiectasia (HHT), can be life threatening, but you’ll likely live a typical, full life if you follow your treatment plan and visit a doctor for regular screenings.
Osler-Weber-Rendu Syndrome, also known as Hereditary Hemorrhagic Telangiectasia (HHT), can vary greatly in its impact on individuals. For some, the symptoms might be mild and manageable, while for others, complications can be more serious. It’s important to closely monitor and manage the symptoms with the help of a healthcare professional who is knowledgeable about HHT. Regular screenings and treatments can significantly improve the quality of life and reduce the risk of severe complications. Staying informed and connected with HHT support groups can also provide valuable resources and support.
