Evaluation of safety and inhibitor development of recombinant factor Ⅷ treatment in hemophilia A patients:a retrospective nationwide multicenter analysis in China
-
摘要: 目的:分析国内血友病A患者接受第3代重组人凝血因子Ⅷ(FⅧ)替代治疗后FⅧ抑制物产生和相关安全性情况。方法:对411例重型和中型血友病A患者进行回顾性分析。结果:411例血友病A患者均为男性,46例仅接受百因止治疗,包括18例既往未接受过FⅧ治疗(PUP)和28例既往接受过FⅧ治疗(PTP);365例接受百因止与其他FⅧ制剂治疗,包括9例PUP和356例PTP。411例患者中13例(3.2%)报告了抑制物产生阳性,包括27例PUP中的3例(11.1%)和384例PTP中的10例(2.6%)。在365例接受百因止与其他FⅧ制剂治疗的患者中,分别有7例(1.9%)、36例(9.9%)和11(3.0%)报告了乙肝表面抗原阳性、乙肝表面抗体阳性和丙肝表面抗体阳性,同时有9例(2.5%)和1例(0.3%)报告了人类免疫缺陷病毒抗体和梅毒螺旋体抗体阳性。在46例仅接受百因止治疗的患者中,未见病毒学阳性结果。结论:中国血友病A患者接受百因止替代治疗总体安全且耐受性良好,抑制物发生率较低。Abstract: Objective:To evaluate the safety and inhibitor development of recombinant factor Ⅷ treatment in hemophilia A patients from multicenter in China.Method:The data of 411 patients with hemophilia A were retrospectively analyzed.Result:All the 411 hemophilia A patients were male.Among them,46 patients received ADVATE only (18 PUP,28 PTP),365 patients received ADVATE plus other factor FⅧ therapy (9 PUP,356 PTP).Overall,13/411(3.2%) patients reported positive for inhibitor development,including 3/27(11.1%) PUP and 10/384(2.6%) PTP.Among 365 patients who received ADVATE plus additional factor Ⅷ therapy,there were 7(1.9%),36(9.9%) and 11(3.0%) patients reported positive for HBs-Ag,HBs-Ab and HCV-Ab;Moreover,there were 9(2.5%) and 1(0.3%) patients reported positive for HIV-Ab and TP-Ab.For 46 patients with ADVATE only,there were no positive virology findings or confirmed exposure to blood components.Conclusion:ADVATE is generally safe and well-tolerated to hemophilia A patients in China,with lower incidence of inhibitors.
