Sci Rep:Xpert MTB/RIF试验检测泌尿系结核的多中心评估

2019-08-15 AlexYang MedSci原创

男生殖系统结核(GUTB)在肺外结核病例中占比多达40%。因为GUTB与推迟就医相关,进而导致严重的后果。因此,GUTB的快速检测是非常必要的。最近,有研究人员评估了利用尿液样本的Xpert MTB/RIF试验在快速检测泌尿系结核(UTB)和利福平抗性肺结核中的表现情况。研究总共包括了302名患者。研究人员对疑似UTB患者利用Xpert、涂片和MGIT 960培养进行了测试,并对阳性案例进行了药物

生殖系统结核(GUTB)在肺外结核病例中占比多达40%。因为GUTB与推迟就医相关,进而导致严重的后果。因此,GUTB的快速检测是非常必要的。

最近,有研究人员评估了利用尿液样本的Xpert MTB/RIF试验在快速检测泌尿系结核(UTB)和利福平抗性肺结核中的表现情况。研究总共包括了302名患者。研究人员对疑似UTB患者利用Xpert、涂片和MGIT 960培养进行了测试,并对阳性案例进行了药物敏感性测试(DST)。试验的表现情况通过MGIT 960培养和综合参考标准(CRS)进行了评估。研究发现,在所有的参与者中,150(49.7%)名参与者具有CRS阳性UTB,其中36名(24%)为培养确认。与培养相比,Xpert和涂片的敏感性分别为94.4%(95%CI: 81.3-99.3%)和22.2%(95%CI: 10.1-39.2%)。与CRS相比,Xpert、涂片和培养的敏感性分别为41.3% (95%CI: 33.4-49.7%), 7.3% (95%CI: 3.7-12.7%)和24.0% (95%CI: 17.4-31.6%)。

最后,研究人员指出,Xpert在利用尿液样本检测UTB方面具有比涂片和培养更好的表现,可以考虑作为UTB诊断的工具。更多的是,Xpert具有比使用尿液培养物的基于DST的MGIT 960更好的表现。
