Acquired hemophilia A AHA is an uncommon but potentially life-threatening hemorrhagic disorder caused by the development of autoantibodies directed against the coagulation factor VIII (FVIII) [3Ð11].

Finally, a test is done to determine the level of antibodies, called inhibitors, produced by the immune system, which is measured in Bethesda units (BU). These same blood

Costs of treatment before immunoadsorption were markedly higher than those associated with the immunoadsorption procedures (i.e., >Can$350,000 and >Can $1,000,000 vs. <$20,000). CONCLUSION: Immunoadsorption appears to be an effective and cost-effective alternative in the management of patients with inhibitors to FVIII.

Acquired factor VIII inhibitor and lupus anticoagulant

Acquired factor VIII inhibitor is a rare occurrence and may cause severe bleeding by interfering with the coagulation cascade. We report an interesting case of a 59-year-old white man with an acquired factor VIII inhibitor and lupus anticoagulant. Clinical findings included large hemor-

High-Dose Intravenous Immunoglobulin Treatment in Two

Acquired inhibitors to coagulation factors are an infrequent coagulation disorder, those directed against factor VIII being by far the most common. In a recent systematic review, Streiff and Ness [1] reported that since 1955 126 cases of factor V (FV) inhibitors had been described. Acquired FV inhibitors may develop

Immunoadsorption (IA): A therapeutic procedure in which plasma of the patient, after separation from the blood, is passed through a medical device which has a capacity to remove immunoglobulins by specifically binding them to the active component (e.g., Staphylococcal protein A) of the device.

Acquired Factor VIII Inhibitors: Pathophysiology and Treatment

Factor VIII and Acquired Inhibitors Factor VIII functions as a cofactor to factor IXa in the tenase complex, and a deficiency of factor VIII thus reduces the generation of thrombin on the surface of activated plate-lets. Factor VIII is synthesized as a 330-kDa precursor pro-tein with an A 1-a 1-A 2-a 2-B-a 3-A 3-C 1-C 2 domain structure.1
