Abstract

Haemophilia A is usually a genetic deficiency of coagulation factor VIII (F VIII). The development of antibodies against F VIII is a well known and frequent complication in the treatment of haemophilia A. Rarely, a F VIII inhibitor arises spontaneously, causing a condition which is known as acquired haemophilia A. We describe a patient with acquired haemophilia A and pemphigus, who presented with spontaneous haematomas of the extremities. Laboratory tests showed an activated partial thromboplastin time (aPTT) of 71 s (normal: 26-36 s), a F VIII concentration of 9% (normal: 60-140%), and a F VIII inhibitor-activity of 7.5 Bethesda Units/ml (B.U./ml, normal: 0). The haematomas disappeared within a few days and the laboratory tests normalized within 6 weeks, after administration of a booster of oral corticosteroids. One and a half years after the corticosteroids were stopped, both the clinical and the laboratory course of the patient has been uneventful. As far as we know, the combination of acquired haemophilia A and pemphigus has been reported in the literature only three times before. The diagnosis acquired haemophilia A should be considered in a patient presenting with a newly arisen haemorrhagic diathesis.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
