Acquired haemophilia a in a woman with autoimmune hepatitis and systemic lupus erythematosus; review of literature
Acquired haemophilia A, secondary to systemic lupus erythematosus (SLE) is a rare bleeding diathesis. Here we report a 37-year-old woman with autoimmune hepatitis who developed SLE and acquired haemophilia caused by factor VIII inhibitors. She presented with spontaneous ecchymosis and haematuria. There were a prolongation of the activated partial thromboplastin time, reduced factor VIII activity and a high titer of FVIII inhibitors. Therapeutic regimen was started with intravenous methylprednisolone pulse, continued with prednisolone, intravenous pulse cyclophosphamide and fresh frozen plasma. After 8 weeks, factor VIII inhibitor assay was negative. Blood Coagul Fibrinolysis 23:71-74 (C) 2011 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins.
