Abstract

目的探讨重型再生障碍性贫血(SAA)患者行异基因造血干细胞移植(allo-HSCT)后发生植入功能不良(PGF)的危险因素。方法回顾性分析111例行allo-HSCT的SAA患者临床资料及移植情况,采用Cox比例风险模型对可能影响PGF的因素进行单因素及多因素分析。结果在111例行allo-HSCT的SAA患者中,共有16例发生了PGF(14.4%)。多因素分析结果显示,非血缘供者(HR=2.656,95%CI 1.204~5.858,P=0.016)及移植前血清铁蛋白浓度(SF)>1 000 µg/L(HR=3.170,95%CI 1.400~7.180,P=0.006)是发生PGF的独立危险因素。结论非血缘供者及移植前SF>1 000 µg/L的患者移植后容易发生PGF。
