At the 2000 American Society of Hematology meeting, we reported the successful treatment of a patient with acquired hemophilia using rituximab (Rituxan). This patient has required no therapy over the past year and has suffered no further hemorrhages. A June 2001 factor VIII level was 35%, and a factor VIII inhibitor level could not be analyzed due to the high level of factor VIII. Since then, three more patients with acquired factor VIII deficiency have received rituximab therapy at the University of Iowa, and are discussed below.
