TYPES OF HEMOPHILIA

There are two types of hemophilia: Hemophilia A, factor VIII(8) deficiency and Hemophilia B, factor IX(9) deficiency.

Hemophilia A (Factor VIII(8) Deficiency)

Hemophilia A is the most common type of hemophilia. It is also known as factor VIII(8) deficiency or classic hemophilia. A person with hemophilia A, has a deficiency or not enough of the factor VIII(8) clotting protein in their blood. There are different levels of hemophilia A: severe, moderate and mild. These levels are based on the amount of factor VIII(8) in their blood. Normal factor VIII activity isabove 50%.. A person with severe hemophilia A has less than 1% of factor VIII(8) in their blood. Factor VIII(8) replacement is needed several times a week to prevent bleeding. Bleeding can be caused by injury or complications. A person with moderate hemophilia A has 1% to 5% of factor VIII(8) in their blood. Bleeds in a person with moderate hemophilia are commonly caused by injury, surgery or dental work. A person with mild hemophilia A have 6% to 50% of factor VIII(8) in their blood. A person with mild hemophilia A should have fewer bleeds than a person with moderate or severe hemophilia A. Mild bleeds are usually caused by injury, surgery or dental work.

Hemophilia B (Factor IX(9) Deficiency)

Hemophilia B is less common than Hemophilia A. It is also known as Factor IX(9) Deficiency or “Christmas disease,” named after the first patient described to have the disease. A person with hemophilia B has a deficiency of factor IX(9) clotting protein in their blood, thus they have a hard time forming clots to stop bleeding. There are three different levels of hemophilia B: severe, moderate and mild. A person with severe hemophilia B has less than 1% of factor IX in their blood. Factor IX(9) replacement is needed several times a month to prevent bleeding. Bleeding can be caused by injury or complications. A person with moderate hemophilia B has 1% to 5% of factor IX in their blood. Bleeds in a person with moderate hemophilia are commonly caused by injury, surgery or dental work. A person with mild hemophilia B has 6% to 50% of factor IX(9) in their blood. A person with mild hemophilia B will have fewer bleeds than a person with moderate or severe hemophilia B. Mild bleeds are usually caused by injury, surgery, or dental work.
