摘要:

收集陕西省结核病防治院2021年10月至2022年7月疑似肺结核住院患者的肺泡灌洗液,同时进行涂片抗酸杆菌染色、分枝杆菌BACTEC MGIT 960液体培养(简称“培养”)及菌种鉴定、GeneXpert MTB/RIF、结核分枝杆菌RNA恒温扩增实时荧光检测技术(simultaneous amplification and testing for Mycobacterium tuberculosis,SAT-TB),并对结果进行分析。以培养法(菌种鉴定结果为结核分枝杆菌复合群)为参考标准,SAT-TB诊断肺结核的敏感度为80.61%(399/495),特异度为87.74%(1259/1435),阳性预测值为69.39%(399/575),阴性预测值为92.92%(1259/1355),约登指数为0.68。SAT-TB技术具有敏感度和特异度较高的特点,对临床快速诊断活动性结核病具有一定的价值。

Abstract:

Alveolar lavage fluid specimens from inpatients with clinical diagnosis of suspected tuberculosis in Shaanxi Provincial Hospital of Tuberculosis Prevention and Treatment from October 2021 to July 2022 were collected, and acid-fast bacilli smear, mycobacterium culture (MGIT 960) and strain identification, GeneXpert MTB/RIF and simultaneous amplification and testing for Mycobacterium tuberculosis (SAT-TB) test were performed. The results were analyzed and evaluated. Taking culture result (MGIT 960) as the standard, the sensitivity of SAT-TB in the diagnosis of tuberculosis was 80.61% (399/495), and the specificity was 87.74% (1259/1435), the positive predictive value was 69.39% (399/575), the negative predictive value was 92.92% (1259/1355), and the Youden index was 0.68. SAT-TB technique has high sensitivity and specificity, is of certain value for rapid diagnosis of active tuberculosis in clinic practice.
