Hemorrhagic pleural effusion related to acquired coagulation factor VIII deficiency: A case report

A patient with acquired hemophilia A (AHA) with hemorrhagic pericardial effusions was admitted to Xiamen Chang Gung Hospital (Xiamen, China) in August 2015. The patient had been experiencing progressive dyspnea for 1 week. Bloody effusion (~6.3 l) was drained from the membrane surrounding the heart over a period of 20 days. Biochemical, cytological and radiological examinations were unable to elucidate the reason for the effusion. Coincidentally, it was discovered that activated partial thromboplastin time prolongation could not be corrected by plasma mixing. Furthermore, immunologic and functional assays identified that the patient had factor VIII-deficient plasma. Finally, the coagulopathy was treated by infusion of cryoagglutinin and steroids to eradicate the coagulation inhibitor. The production of cardiac bloody effusions did not recur. Notably, the patient was diagnosed with AHA accompanied by the rare complication of pericardial effusions. The present case was the first to report AHA with the complication of pericardial effusions.
