Abstract

目的比较预处理方案含猪抗人淋巴细胞免疫球蛋白(pALG)或兔抗人胸腺细胞免疫球蛋白(rATG)替代供者异基因造血干细胞移植(AD allo-HSCT)治疗重型再生障碍性贫血(SAA)患者的疗效及安全性。方法回顾性分析2006年1月至2016年11月46例接受AD allo-HSCT SAA患者的临床资料,按预处理方案包含rATG或pALG分为两组,比较两组植入率、移植相关并发症发生率及转归。结果rATG组30例患者均获得粒细胞植入,27例患者获得血小板植入。pALG组16例患者粒细胞及血小板均植入。两组患者在移植后急性移植物抗宿主病(aGVHD)(P=0.475)、Ⅲ~Ⅳ度aGVHD(P=0.876)、慢性移植物抗宿主病(cGVHD)(P=0.309)、广泛型cGVHD(P=0.687)、移植物排斥(GR)(P=0.928)、血流感染(P=0.443)、侵袭性真菌病(P=0.829)、巨细胞病毒血症(P=0.095)发生率方面差异均无统计学意义。rATG组中位随访14(2~102)个月,预期5年总生存率为(75.1±8.2)%;pALG组中位随访23(4~63)个月,预期5年总生存率为(53.6±13.3)%,差异无统计学意义(P=0.190)。结论SAA患者行AD allo-HSCT,预处理方案应用pALG可取得与rATG相近疗效,且并不增加GVHD、GR及感染等移植后并发症的发生率。
