[Cyclosporine A as an effective treatment for a patient with acquired hemophilia A complicated with diabetes mellitus and ischemic heart disease].

Acquired hemophilia A (AHA) is a rare coagulation disorder due to the development of an autoantibody against and inhibitor of coagulation factor VIII. It has been reported that immunosuppressive therapy with corticosteroids, cyclophosphamide, azathioprine and vincristine are effective to decrease this inhibitor. When corticosteroids and cytotoxic drugs are ineffective, cyclosporine A (CyA) may be effective as a second-line salvage therapy.
