Successful treatment of acquired hemophilia A with recombinant porcine factor VIII

Acquired hemophilia A is a rare, potentially life-threatening disease resulting from autoantibodies against coagulation factor VIII. We report the case of a patient with acquired hemophilia A and severe bleeding after incision of a peritonsillar abscess. Treatment with high dose factor VIII and recombinant activated factor VII failed to control bleeding. However, a single infusion of recombinant porcine factor VIII stopped bleeding efficiently and resulted in measurable factor VIII levels.
