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. Except for postpartum conditions, AHA usually occurs in elderly patients who are often already suffering from diabetes mellitus, ischemic heart disease and/or hyperlipidemia. However, immunosuppressive and cytotoxic drugs may have adverse effects on these patients. We report on a 66-year-old man who developed AHA after colon cancer resection (factor VIII inhibitor: 61 Bethesda units/ml, aPTT : 97.9 s). Since he already had both diabetes mellitus and ischemic heart disease, we abandoned treatment with corticosteroids and oral cyclophosphamide was started, but was switched to CyA because of leukopenia. Within 3 months of starting the CyA treatment, aPTT levels returned to normal and 4 further months were required for complete eradication of the inhibitor. This case revealed that CyA is as effective as corticosteroids for AHA. For patients with AHA who have unfavorable complications due to corticosteroids and cytotoxic drugs, CyA could be a potential first-line drug. |
