Acquired Hemophilia

Father and Son

Acquired Hemophilia is a rare but dangerous blood disorder. Each year, it occurs in 1 to 1.5 out of a million people. In a person with acquired hemophilia, the body's natural clotting process is disrupted. The body produces antibodies that fight its own blood clotting proteins. The condition can lead to spontaneous, uncontrolled bleeding, most often in the skin and soft tissues.

Acquired hemophilia can occur in men and women with no personal or family history of bleeding disorders. In about half of diagnosed cases, the cause of acquired hemophilia is unknown. However, the following factors may increase the likelihood of contracting the disease.

  • Over age 50 (mean age of 64)
  • Autoimmune conditions such as rheumatoid arthritis
  • Cancer
  • Reaction to a prescribed drug
  • A recent pregnancy (although rare)

If you experience prolonged bleeding, contact emergency personnel and your physician immediately.
