A coagulation Factor V inhibitor developed in a man 75 yr of age in association with an anaplastic malignancy and drug treatment (including the aminoglycoside antibiotic, gentamicin). The patient did not bleed abnormally, despite both surgical challenge and plasma Factor V activity of less than 1%. The inhibited plasma had grossly prolonged prothrombin and activated partial thromboplastin times...

We present the case of a 70-year-old woman found to have a prothrombin time (PT) of 26.8 seconds (s) and an activated partial thromboplastin time (PTT) of 71 s prior to an elective endoscopic retrograde cholangiopancreatography for symptomatic choledocholithiasis. She had no personal or family history of bleeding, thrombosis, autoimmune diseases, miscarriages, recent surgery or antibiotic use, ...

A 71 -yr-old male was seen because of the development of severe bleeding diathesis secondary to an acquired factor V inhibitor. The lack of clinical and laboratory response to fresh frozen plasma prompted us to treat him with platelet transfusions during 4 separate bleeding episodes; on each occasion he received 1 0-1 5 U of homologous platelet concentrates. There was a remarkable clinical resp...

background: factor viii inhibitor is one of the most problems in the treatment of hemophilia. patients with hemophilia who have inhibitors are capable of severe hemorrhage and treatments of these patients are more expensive and more difficult than those patients without inhibitor. the aim of present study was to determine the prevalence of inhibitor and to assess the necessity of screening of t...

conclusions treatment strategies in acquired hemophilia are based on two major objectives. during the acute stage, effective control of bleeding is critical. the ultimate therapeutic goal during the subacute phase is the elimination of the inhibitors targeting factor viii. here, we present this case and will review current literature regarding therapeutic approaches to this rare condition in th...

The development of a high-titer factor V inhibitor is described in a patient who underwent orthotopic liver transplantation followed by porcine xenoperfusion after an acute rejection episode. The inhibitor showed no cross-reactivity to either porcine or bovine factor V, nor was it accessible to human platelet factor V. The limitations of treatment modalities including intravenous immunoglobulin...
