title: Factor V Deficiency in Korean Patients: Clinical and Laboratory Features, Treatment, and Outcome.
abstract: Due to rarity of factor V (FV) deficiency, there have been only a few case reports in Korea. We retrospectively analysed the clinical-laboratory features of FV deficiency in 10 Korean patients. Between January 1987 and December 2013, 10 case reports published in a Korean journal or proceedings of Korea Society on Thrombosis and Hemostasis were reviewed. Severity is defined as mild (> 5% of factor activity), moderate (1%-5%), and severe (< 1%). The median age at diagnosis, six males and four females, was 26 years (range, 1 month-73 years). Six of 10 patients were classified as moderate, three as mild, and one as severe disease. Eight patients were diagnosed as inherited FV deficiency. The most frequent symptoms were mucosal tract bleedings (40%) such as epistaxis, and menorrhagia in female. Hemarthroses and postoperative bleeding occurred in one and four patients, respectively. Life-threatening bleeding episodes occurred in the peritoneal cavity (n = 2), central nerve system (n = 1), and retroperitoneal space (n = 1). No lethal haemorrhages happened to patients with mild disease. The majority of bleeding episodes were controlled with local measures and fresh-frozen plasma replacement. Two acquired FV deficient-patients showing life-threatening haemorrhages received the immunosuppressive therapy, but one of them died from postoperative bleeding complications. Despite the small sample size of this study due to rarity of the disease, we found that Korean patients with FV deficiency had similar clinical manifestations and treatment outcomes shown in previous studies.
