Hemophilia

Understanding Hemophilia

Hemophilia is a bleeding disorder caused by the body’s inability to accomplish the natural clotting process. People with hemophilia experience bleeds because there is an inadequate amount of a blood protein known as thrombin.

There are approximately 200,000 people worldwide with hemophilia A and hemophilia B. Traditional therapies may temporarily allow the body to produce enough thrombin to support clotting.

Clotting and thrombin

Clotting starts when platelets in blood collect at the site of injury to begin the healing process. Thrombin is critical to clotting and sealing the wound. It converts fibrinogen into fibrin, establishing a network to help more platelets accumulate.

Relative thrombin levels(%) in hemophilia

The severity of hemophila is associated with how much thrombin a person can make. As shown on the left, individuals with 100% thrombin demonstrate no symptoms of hemophilia. To get more info, including how antithrombin may play a role, see the Hemophilia Brochure below.
