Clinica Chimica Acta:结核病阈值是否有助于活动性结核病的诊断?

2020-07-19 MedSci原创 MedSci原创

这项研究旨在确定增加的T-SPOT.TB截止值是否有助于诊断活动性肺结核(ATB)。

这项研究旨在确定增加的T-SPOT.TB截止值是否有助于诊断活动性肺结核(ATB)。

研究人员通过招募疑似患有结核病的患者,以推导可帮助诊断ATB的T-SPOT.TB阈值,该阈值随后在实际临床实践中得到了验证。

总计701名经过T-SPOT.TB分析的疑似患有结核病的成年患者被包括在派生队列中。 与潜伏性结核感染(LTBI)相比,ATB组中ESAT-6(U = 43583,P = 0.0002)和CFP-10(U = 41753,P <0.0001)点形成细胞(SFC)的数量显着增加。 组。 根据接收器工作特性分析,当使用37.5个SFC / 2.5×105电池的临界值来区分ATB和LTBI时,灵敏度为57.5%(95%置信区间[CI]为50.7%-64.2%),而 特异性为59.8%(95%CI 55.2%-64.2%)。 阈值173.5 SFC / 2.5×105可用于获得<90%的特异性以区分ATB和LTBI。 验证队列中较高的T-SPOT.TB阈值的诊断准确性与派生队列中的类似。

研究结果表明,在高负担国家,173.5 SFCs/2.5×105的较高阈值可能有助于对疑似结核病患者的ATB诊断。
