Acquired hemophilia is a rare but potentially life-threatening bleeding disorder caused by the development of autoantibodies directed against plasma coagulation factors, most frequently factor VIII (FVIII). [1, 2] Autoantibodies against other factor proteins have also been reported. [1] Because inhibitors to FVIII are the most frequently observed in clinical practice, this article focuses on the etiology and management of FVIII autoantibody inhibitors, or acquired hemophilia A.
Diagnosis of acquired hemophilia can be difficult, both because the condition is rare and because the patient does not have the usual personal or family history of bleeding episodes, such as is seen in congenital hemophilia. [1] Moreover, the clinical signs and symptoms of acquired hemophilia differ from those of hereditary hemophilia.
The severity of acquired hemophilia at clinical presentation can also make its management challenging. Treatment strategies for acquired hemophilia have 2 major objectives. During acute bleeding episodes, effective control of bleeding manifestations is the primary objective. However, the ultimate therapeutic goal is to eliminate the inhibitor and cure the disease.
