Abstract

To investigate the feature of underlying disorders, clinical symptoms, diagnosis and treatment strategies of patients with acquired hemophilia(AH). The clinical data and laboratory tests results of 22 patients with AH from March 2010 to June 2014 were retrospectively analyzed. A total of 22 patients with AH were enrolled in our study, including 20 patients diagnosed as acquired hemophilia A (AHA) and 2 as acquired hemophilia B (AHB). Among the AHA patients, there were 10 males and 10 females with the median age of 37.5 (range, 2-95) years old. The median activity of FVIII (FVIII:C) of the 20 AHA patients was 1.9% (0.5%-39.0%). Soft tissue hematoma (80.0%) and subcutaneous bleeding (75.0%) were the most common clinical symptoms. Two male children were diagnosed as AHB (age 1 and 3 years old, respectively) with mild bleeding symptoms, and the activities of FIX (FIX:C) were 5.0% and 16.0%, respectively. In addition, an underlying disorder was found in 7 patients (31.8%). In laboratory testing, all patients had prolonged APTT, normal PT, decreased FVIII:C or FIX:C, positive antibody screening test or antibody titer (2-32 BU), and negative for lupus anticoagulant and anticardiolipin antibody. Nineteen out of 20 patients were treated...Continue Reading
