Clinica Chimica Acta:在骨和关节结核的诊断中Xpert MTB/RIF值与T-SPOT值的比较研究

2020-02-18 MedSci MedSci原创

本研究在骨骼和关节结核的诊断中评价了Xpert MTB/RIF和T-SPOT的应用价值。

本研究在骨骼和关节结核的诊断中评价了Xpert MTB/RIFT-SPOT的应用价值。

20184月至20192月,在河南郑州骨科医院就诊的102例疑似骨关节结核(BJTB)患者被纳入本研究。分别用脓液标本和外周血进行Xpert MTB/RIFT-SPOT结核试验。在综合参考标准(CRS)的基础上进行评估的Xpert MTB/RIFT-SPOT诊断性能。

研究人员总共对73例疑似BJTB进行了登记和归类,包括12例确诊的BJTB27例可能的BJTB34例非BJTB 当使用CRS作为参考时,Xpert MTB / RIF分析的特异性,PPVNLR值显著高于T-SPOT.TB分析(97.1vs. 82.4%,p <0.05 96.7vs. 85.4%,p <0.05 0.26 vs. 0.12p <0.05)。 但是,T-SPOT的灵敏度,NPVPLR显著高于Xpert MTB / RIF检测(89.7vs.74.4%,p <0.05; 87.5vs 76.7%,p <0.05; 5.08 vs 2.52p <0.05)。 Xpert MTB / RIFT-SPOTAUC分别为0.8570.860 但是,差异没有统计学意义。 Xpert MTB / RIFT-SPOT在诊断BJTB中具有中等一致性。

研究结果表明,T-SPOT.TB检测的灵敏度与Xpert MTB / RIF的特异性相结合,不仅缩短了诊断时间,而且提高了BJTB的诊断准确性,降低了误诊率。因此,对BJTB的早期诊断有一定的参考价值。
