摘要 目的探讨异基因造血干细胞移植(allo-HSCT)后应用实时定量聚合酶链反应(RO—PCR)技术检测巨细胞病毒(CMV)DNA拷贝数,以指导对CMV感染的临床诊断及治疗。方法回顾分析接受allo—HSCT的23例患者,按移植方式分为同胞全相合HSCT11例,亲缘间单倍体HSCT12例。移植后均采用RQ-PCR技术检测CMV—DNA,〉1000拷贝数/ml为CMV阳性。全部患者在预处理阶段-9天至-2天应用更昔洛韦预防CMV感染。抢先治疗首选更昔洛韦,血常规低于正常者选用缬更昔洛韦或膦甲酸钠。结果23例allo—HSCT患者中共13例发生14例次(56.5%)CMV感染,2例发生CMV病(8.7%)。同胞全相合的11例患者发生CMV感染2例(18.2%),亲缘间单倍体的12例患者发生CMV感染11例12例次(91.7%)。发病中位时间为+41天(+30.+62天)。经治疗12例患者13例次CMV—DNA转阴(92.3%),1例死亡(7.7%)。结论RQ.PCR技术检测血浆CMV-DNA是监测CMV感染的可靠手段,有利于指导临床抗CMV治疗,减少CMV病的发生。
