摘要: 目的 探讨T细胞酶联免疫斑点法(T-SPOT.TB)联合利福平耐药结核分枝杆菌实时荧光定量核酸扩增检测技术(XpertMTB/RIF)在老年艾滋病患者合并结核分枝杆菌(MTB)感染中的诊断价值。方法 选取衡水市第三人民医院2022年5月至2024年5月收治的86例老年艾滋病疑似MTB患者,根据病理检查结果分为艾滋病合并MTB(研究组)和艾滋病非MTB(对照组);均进行MTB培养、T-SPOT.TB和XpertMTB/RIF检测;Kappa分析T-SPOT.TB联合XpertMTB/RIF诊断艾滋病合并MTB与金标准的一致性;绘制ROC曲线以及四格表分析T-SPOT.TB联合XpertMTB/RIF诊断艾滋病合并MTB感染的价值。结果 研究组血γ-干扰素、T-SPOT.TB阳性检出率以及XpertMTB/RIF阳性检出率均高于对照组(P<0.05)。T-SPOT.TB诊断艾滋病合并MTB感染的AUC为0.810,XpertMTB/RIF诊断艾滋病合并MTB感染的AUC为0.835,二者联合诊断艾滋病合并MTB感染的AUC为0.910。T-SPOT.TB、XpertMTB/RIF及联合诊断艾滋病合并MTB感染的Kappa值分别为0.624、0.674和0.825。T-SPOT.TB诊断艾滋病合并MTB阴阳性的准确度为82.56%,XpertMTB/RIF诊断艾滋病合并MTB阴阳性的准确度为84.88%,二者联合诊断艾滋病合并MTB阴阳性的准确度为91.86%。结论 T-SPOT.TB联合XpertMTB/RIF可提高诊断艾滋病合并MTB准确度,可作为临床辅助诊断艾滋病合并MTB的方法。

Abstract: Objective Exploring the diagnostic value of T-cell enzyme-linked immunospot assay (T-SPOT.TB) combined with rifampicin-resistant Mycobacterium tuberculosis real-time fluorescence quantitative nucleic acid amplification detection (XpertMTB/RIF) in geriatric AIDS patients with Mycobacterium tuberculosis(MTB) infection. Methods From May 2022 to May 2024, 86 elderly patients with AIDS suspected MTB in Hengshui Third People's Hospital were gathered and separated into AIDS complicated with MTB (research group) and AIDS without MTB (control group) according to the pathological examination results. MTB culture, T-SPOT.TB and XpertMTB/RIF were performed. Kappa analysis was applied to evaluate the consistency between T-SPOT.TB combined with XpertMTB/RIF and the gold standard for diagnosing MTB coinfection in AIDS patients. ROC curve and four grid table were plotted to analyze the value of the combination of T-SPOT.TB and XpertMTB/RIF in the diagnosis of AIDS complicated with MTB infection. Results The blood γ-interferon, the positive detection rates of T-SPOT.TB and XpertMTB/RIF in the research group were higher than those in the control group (P<0.05). The AUC of T-SPOT.TB in diagnosing AIDS with MTB infection was 0.810, that of Xpert MTB/RIF in diagnosing AIDS with MTB infection was 0.835, and the AUC of the two in diagnosing AIDS with MTB infection was 0.910. The Kappa values of T-SPOT.TB, Xpert MTB/RIF and their combined diagnosis for AIDS with MTB infection were 0.624, 0.674 and 0.825, respectively. The accuracy of T-SPOT.TB in the diagnosis of AIDS with MTB was 82.56%, the accuracy of XpertMTB/RIF in the diagnosis of AIDS with MTB was 84.88%, and the accuracy of the combined diagnosis for AIDS with MTB was 91.86%. Conclusions T-SPOT.TB combined with XpertMTB/RIF can improve the accuracy of diagnosis of AIDS with MTB, and can be used as a clinical auxiliary diagnosis method for AIDS patients complicated with MTB.
