Acquired hemophilia (AH) is an extremely rare condition in which auto-antibodies (inhibitors) against clotting Factor VIII induce acute and life-threatening hemorrhagic diathesis due to abnormal blood clotting. The mortality rate of AH is as high as 16% and current treatment options are associated with adverse side effects. We investigated a therapeutic approach for AH called the modified Bonn Malmoe Protocol (MBMP). The aims of MBMP include suppression of bleeding, permanent elimination of inhibitors, and development of immune tolerance, thereby avoiding long-term reliance on coagulation products. The protocol included: 1) immunoadsorption for inhibitor elimination, 2) Factor VIII substitution, 3) intravenous immunoglobulin, and 4) immunosuppression. Thirty-five high-titer patients with critical bleeding that underwent MBMP were evaluated. Bleeding was rapidly controlled during 1 or 2 apheresis sessions and no subsequent bleeding episodes occurred. Inhibitor levels decreased to undetectable levels within a median of 3 d (95% CI, 2-4 d), factor substitution was stopped within a median of 12 d (95% CI, 11-17 d), and treatment was completed within a median of 14 d (95% CI, 12-17 d). Long-term follow-up (7 mo-7 y) showed an overall response rate of 88% for complete remission (CR). When cancer patients were excluded, the CR rate was 97%.
