总而言之,细菌移位似乎不是预测HIV合并HCV感染的肝硬化患者临床结局的预测指标。

本研究的主要目的是评价细菌移位是否能够预测HIV合并HCV感染的肝硬化患者的临床结局。

本研究共纳入282例HIV合并HCV感染的肝硬化患者(先前无失代偿性肝硬化)。研究者检测编码保守序列16S rRNA亚单位的基因序列、脂多糖(LPS)、可溶性CD14(sCD14)的血清水平。研究主要终点为首先出现失代偿性肝硬化(LD)和任何原因的死亡。次要终点为出现失代偿性肝硬化(LD)、肝相关死亡(LRD)和任何原因的死亡。中位随访时间为51个月(27-72个月),67例患者(24%、95%:19-29)在随访期间发生了LD或者死亡。16S rDNA、LPS和sCD14的基线血清水平与本研究主要终点的发生没有相关性。根据血清16S rDNA水平预测平均生存时间,在16S rDNA血清水平分别为< 83、83-196、197-355、> 355 copies/muL时,平均生存时间分别为:78、72、81和82个月,P值为0.5,不受LD和死亡的影响。根据脂多糖(LPS)血清水平预测平均生存时间,在LPS血清水平分别为< 0.1、0.1-0.6、0.6-1.5、> 1.5 IU/mL时,生存时间分别为76、71、77和81个月,P值为0.4。本研究中细菌移位的血清学标志物的基线水平与次要终点的发生没有相关性。

总而言之,细菌移位似乎不是预测HIV合并HCV感染的肝硬化患者临床结局的预测指标。
