ABSTRACT

Acute gastrointestinal bleeding (GIB) is a frequently encountered medical emergency and it can be life-threatening depending on the etiology and the clinical condition of the patient. The most common causes of GIB are peptic ulcer disease, aspirin-induced gastritis, variceal hemorrhage, esophagitis, neoplasms like gastric cancer. Acquired hemophilia causing acute gastrointestinal bleed is extremely rare and only a few cases are reported worldwide. Acquired hemophilia A (AHA) is a rare disorder caused by the production of autoantibodies that inactivates clotting factor VIII. We present a case of upper gastrointestinal bleed due to AHA which was undiagnosed for two years. A 74-year-old patient with a history of myasthenia gravis, presented with anemia, and GIB. She underwent multiple endoscopies without a clear bleeding source. Coagulation studies showed isolated activated partial thromboplastin time prolongation which was not corrected by mixing study. Factor VIII activity was low and Bethesda titer showed elevated inhibitor levels. Factor Eight Bypassing Agent, recombinant factor VIIa, and steroids were given to control bleeding. Her clinical condition worsened, and she passed away. Elderly patients presenting with an undiagnosed source of GIBs, inconclusive endoscopic studies should be evaluated for acquired coagulopathies, especially in those with a history of autoimmune diseases and malignancies. Prompt diagnosis and treatment are warranted as it carries a high mortality. Part of the case presentation was presented as an abstract at a regional conference.
