What is Bernard-Soulier syndrome?
Bernard-Soulier syndrome (BSS) is a rare disorder that affects the way your blood clots. Blood clotting is the process that keeps you from excessively bleeding when you’re injured.
Platelets and plasma, two components of your blood, play important roles in forming blood clots. People with Bernard-Soulier syndrome tend to have fewer platelets than usual (thrombocytopenia). Their platelets are also bigger than usual. Because of this, people with Bernard-Soulier syndrome usually bleed and bruise easily.
How common is Bernard-Soulier syndrome?
Bernard-Soulier syndrome is rare. Experts estimate that it affects only about 1 in 1 million people worldwide.
Symptoms and Causes
What are the symptoms of Bernard-Soulier syndrome?
Babies with Bernard-Soulier syndrome typically show symptoms early in life. People with Bernard-Soulier syndrome usually experience:
Easy bruising that takes longer than usual to heal.
Excessive bleeding from minor cuts or injuries.
Frequent nosebleeds (epistaxis).
Bleeding under their skin (petechiae).
Unusually heavy menstrual bleeding (menorrhagia).
What causes Bernard-Soulier syndrome?
Bernard-Soulier syndrome is a genetic disorder, meaning you have it because of a gene change (mutation) present at birth. It’s also hereditary, meaning your parents pass down this gene mutation to you.
Bernard-Soulier syndrome occurs because of mutations in the GP1BA, GP1BB or GP9 genes. All of these genes affect how your body forms blood clots.
Diagnosis and Tests
How is Bernard-Soulier syndrome diagnosed?
Your healthcare provider uses blood tests to diagnose Bernard-Soulier syndrome. The blood tests check your platelet count and look for the gene mutations that cause Bernard-Soulier syndrome. Your provider may also look at your blood under a microscope to see if your platelets are unusually large. A test called a platelet flow cytometry measures the amount of glycoproteins 1BA, 1BB and 9 on the platelet surface.
Management and Treatment
How do you treat Bernard-Soulier syndrome?
Bernard-Soulier syndrome treatment usually focuses on preventing excessive bleeding and avoiding complications of BSS. Your healthcare provider may recommend that you:
Avoid medications that increase bleeding risks, such as nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin or antihistamines.
Brush your teeth with a soft-bristled toothbrush to lower the chances of bleeding gums.
Learn how to apply pressure appropriately to stop nosebleeds.
Limit or avoid foods and drinks such as alcohol and refined sugars that can affect your platelet count.
Register with a 24-hour emergency center that can treat you for emergency bleeding at any time of the day.
Take iron supplements if you’re iron-deficient.
Wear a medical alert bracelet or tag that clearly identifies your diagnosis.
Treatment for Bernard-Soulier syndrome may also include:
Platelet transfusions: This is typically the first-line treatment for people with BSS who have an emergency bleeding episode or are preparing for surgery. You receive donor platelets through an intravenous (IV) line in a platelet transfusion. The platelets assist with blood clotting.
Antifibrinolytic therapy: Antifibrinolytic agents are drugs that help your blood to clot. Your provider may give you tranexamic acid (Cyklokapron®) to control bleeding. Tranexamic acid is a type of antifibrinolytic agent.
Prevention
How can I prevent Bernard-Soulier syndrome?
There’s no way to prevent Bernard-Soulier syndrome. If you have the gene mutation that causes BSS or think you may, it’s a good idea to consider genetic testing and genetic counseling. A genetic counselor can help you understand the risks and effects of passing BSS to your children.
Outlook / Prognosis
What is the outlook for Bernard-Soulier syndrome?
Most people with Bernard-Soulier syndrome can live typical lives. If you have BSS, you’ll have to take extra precautions to avoid injuries. For example, you may need to avoid participating in contact sports, which increases your risk of injuries.
You’ll also need to see your primary care provider regularly to stay in good overall health. You and your care team need to plan any elective surgeries carefully. You also may need a platelet transfusion before undergoing an operation.
