Abstract

Acquired factor VIII deficiency is very rare, often fatal. It is associated with pregnancy, autoimmune diseases, malignancy, and drugs, although no underlying cause is found in 50%. A 49-year-old male was referred with right shoulder bruising. The coagulation test showed a prolonged activated partial thromboplastin time. The factor VIII level was less than 1%, and the factor VIII inhibitor antibody titer was 246 Bethesda units/mL. The findings were compatible with acquired factor VIII deficiency. He had consumed the dried gallbladder of a cobra, Naja naja, for two weeks, it contained venom. After the initial treatment with factor VIII, he did not take supplemental coagulation factor VIII. The patient was readmitted with left forearm swelling. He lost consciousness suddenly and brain computed tomography (CT) revealed a subdural hematoma. Despite administering recombinant factor VII, his bleeding was not controlled and he died.
