Acquired Factor VIII Inhibitor in a Non-Haemophilic Patient: Successful Treatment with Plasma Exchange Associated with Factor VIII Concentrate and Immunosuppressors

Abstract

We report the successful treatment of a 55-year-old man with an acquired factor VIII inhibitor, the appearance of which followed surgery for a carcinoma of the biliary tract. The patient, who had recurrent life-threatening bleeding episodes, was treated with intensive plasmapheresis, factor VIII concentrates, azathioprine and methylprednisolone. Disappearance of the inhibitor was observed after the second series of plasma exchanges. Controls 2 and 3 months after treatment confirmed the complete absence of the inhibitor and normal levels of factor VIII. The crucial role of plasma exchange is considered and discussed.
