Acquired factor VIII inhibitor.

چکیده
PERSISTENT or uncontrolled bleeding is one of the most feared consequences of any surgical procedure. Numerous factors can contribute to its etiology. Among these, both inherited and acquired disorders of coagulation and/or thrombocyte function need to be taken into account. Acquired hemophilia can be caused by antibodies to coagulation factors. Antibodies can arise in hemophilic or nonhemophilic patients. In the former case, patients are treated with Factor VIII concentrate and develop alloantibodies. Nonhemophilic patients produce autoantibodies (mostly against Factors VIII and IX), and this is believed to be an autoimmune reaction. The estimated annual incidence rate of clinically apparent bleeding caused by autoantibodies is 1.48/million inhabitants, or approximately 450 patients in the United States per year. The incidence of the disease seems to be increasing; it is more prevalent in elderly patients and it can be successfully treated if diagnosed adequately and early. Here, we present a case of massive and long-lasting bleeding in a nonhemophilic patient undergoing extensive visceral surgery.
