Hemophilia is a bleeding disorder characterised by deficiency of clotting factor in the blood. Due to inheritance patterns, hemophilia mainly affects males. “Hemophilia affects 1 in 5,000 male births in the U.S. and approximately 400 babies are born with hemophilia each year,” according to the Hemophilia Federation of America. “About 400,000 people worldwide are living with haemophilia. About 20,000 people in the United States have hemophilia. All races and economic groups are affected equally.”

Types of hemophilia: the most common types of congenital hemophilia are hemophilia A and B. Hemophilia A is also called classic hemophilia. This is the most common type of congenital hemophilia. The cause of bleeding in this type of hemophilia is deficiency of factor VIII. The next most common type of hemophilia is hemophilia B, also called Christmas disease. This type of hemophilia develops when factor IX is deficient. Acquired hemophilia is different from congenital hemophilia.

Acquired hemophilia: Acquired hemophilia, usually seen in adults, can develop consequent to illness, medications, or pregnancy. In this type of hemophilia, antibodies develop against clotting factors and these antibodies inactivate the clotting factors leading to bleeding. This type of hemophilia usually resolves when the antibody levels are controlled.

“Acquired hemophilia is not hereditary, this is an autoimmune disorder,” says Leah Fuller, CPC, Associate Consultant, Pinnacle Enterprise Risk Consulting Services, LLC, CO. “This means the body mistakenly attacks healthy tissue and cells, specifically clotting factors, which in turn leads to excessive bleeding. In some cases of acquired hemophilia the patient has an underlying issue, in others, the cause is unknown. Congenital hemophilia is hereditary and is distinguished by a deficiency of certain clotting factors which occurs at birth. The provider should document in the medical record the type of hemophilia a patient has been diagnosed with.”

Von Willebrand Factor has an important role to play to maintain the Factor VIII levels in the blood. 

What is von Willebrand Factor? Von Willebrand Factor is a large protein that binds to clotting factor VIII to protect it and help platelets bind to injured blood vessels. It is used to help the body form blood clots.

“von Willebrand Disease is the most common type of bleeding disorder, affecting an estimated 1% of the world’s population,” acccording to the Hemophiila Federation of America.
