Abstract:
Objective:To investigate the treatment efficacy of recombinant activated factor Ⅶ (rFⅦa) for bleeding among patients with hematologic disorders.
Methods:A total of 38 times of bleeding in 31 patients with hematological disease treated with rFⅦa were analyzed retrospectively.
Results:The clinical effective rate of rFⅦa for bleeding management in acquired hemophilia A (AHA) patients/hemophilia patients with inhibitor, acute promyelocytic leukemia (APL) patients and patients with non-APL leukemia was 90% (9/10) , 71.4% (5/7) and 60.0% (3/5) , respectively, which was higher than that in patients following HSCT (30.8%) . The clinical effective rate of rFⅦa for patients with bleeding score of 2 (100.0%) was higher than that with 3 (66.7%) and 4 (54.1%) . The effective rate of rFⅦa was 25.0% (2/5) in 5 patients with cerebral hemorrhage, 66.7% (6/9) in 9 patients with hematuria and 41.7% in 12 patients with gastrointestinal hemorrhage. The curative effect for 3 patients with joints and muscle bleeding and 5 patients with skin, nasal, pharyngeal and gum bleeding was excellent. Following HSCT, among patients with bleeding score of 4 points, high dose and repeated use of rFⅦa did not necessarily achieve a good effect. Among AHA/hemophilia patients with inhibitors and patients with acute leukemia who had bleeding score of 4 points, the use of low dose FⅦa could achieve good therapeutic effect, however the efficacy of lowest dose (22.5 μg/kg) rFⅦa was poor.
Conclusions:The hemostasis efficacy of rFⅦa is affected by various factors such as diseases, bleeding sites, bleeding score and so on. The use of rFⅦa can achieve good efficacy for bleeding management in AHA patients/hemophilia patients with inhibitor, APL patients and patients with non-APL leukemia. However the efficacy of rFⅦa for bleeding of patients after HSCT is poor. Early use of rFⅦa is important for successful hemostatic treatment. Management of underlying condition is as important as hemostatic treatment.
