Successful treatment of acquired factor VIII inhibitors with cyclosporin

Abstract

The treatment of Factor VIII inhibitors remains controversial and no standard therapy exists. We describe in this report two consecutive patients with this inhibitor that responded to cyclosporin. Clinical improvement of the bleeding diathesis, a return to normal of the PTT, a decrease in the level of the inhibitor, and a return to normal of the factor VIII level followed use of this drug. We believe that cyclosporin is effective in the treatment of factor VIII inhibitors and deserves further investigation.
