摘要 目的分析肝移植供受体间HLA匹配情况对肝移植术后受体HCMV感染的影响。方法回顾性分析我院HBV感染相关终末期肝移植患者移植术前供受体间HLA-A、B、DR位点的匹配情况,根据供受体间HLA-A、B、DR匹配位点匹配情况进行分组,同时测定HCMV病毒血症发生率、发生时间,其中pp65采用免疫组化方法检测,HLA位点检测通过序列特异性聚合酶链式反应(SSP-PCR)方法检测。结果肝移植术前HLA-A位点匹配数为0、1、2三组中,术后pp65阳性细胞计数中位数分别为5(2~17),6(2~15),和7(7~8),三组间pp65阳性细胞数无统计学差异(P=0.915);但在pp65检出时间方面,两个位点均匹配组检出时间为8周,而另外两组均为2周,三组间有统计学差异(P=0.04)。HLA-B位点匹配数为0、1、2三组中,术后pp65阳性细胞计数中位数分别为5(2~17),7(2~17),和5(4~15),(P=0.157);三组检出时间均为2周(P=0.653)。HLA-DR位点匹配数为0、1两组中,pp65阳性细胞计数中位数分别为6(2~15)和6(2~17),两组间无pp65阳性细胞数无统计学差异(P=0.672);两组检出时间均为2周(P=0.521)。结论 HLAA位点匹配程度可影响术后HCMV感染发生时间,但并不影响HCMV感染率。
