We report three patients with acquired inhibitors against F VIII:C/F vW:Ag complex. Two patients had acquired hemophilia A. The three patients presented with bleeding diathesis. Case 1 was a 19 years old woman with Graves-Basedow disease; case 2 was a 40 years old woman with systemic lupus erythematosus of four years; and case 3 a 38 years old woman who had had rheumatoid arthritis for five years and was in her 3d month postpartum. The F VIII:C level was below 8 U/dL in all cases. The F vW:Ag, ristocetin cofactor and platelet aggregation with ristocetin were diminished in the two cases with von Willebrand. Inhibitor to F VIII:C was 50, 38 and 20 Bethesda units, respectively, for cases 1, 2 and 3. The three patients showed clinical response to DDAVP and cryoprecipitates with partial response in laboratory tests. All patients responded to corticosteroid treatment, but immunosuppressive treatment was necessary in case 3.
