摘要:

目的: 系统评估γ-干扰素释放试验(interferon-γ release assay,IGRA)在不同标本类型及检测方法中对成人肺外结核(extrapulmonary tuberculosis,EPTB)的诊断价值,为优化临床诊断路径提供循证依据。方法: 系统检索2014年1月至2025年5月期间的PubMed、Web of Science及Cochrane图书馆数据库,纳入比较商业化IGRA[结核感染T细胞斑点试验(T-SPOT.TB)或QuantiFERON-TB Gold系列]与复合参考标准[培养和(或)临床诊断]的诊断准确性研究。采用双变量随机效应模型合并敏感度、特异度,并进行亚组分析(标本类型、检测方法、疾病类型等)和Meta回归。结果: 共纳入28项研究(32573例参与者)。总体合并敏感度、特异度和曲线下面积(area under curve,AUC)值分别为0.83(95%CI:0.79~0.87)、0.86(95%CI:0.82~0.90)和0.909。IGRA检测体液样本的敏感度与血液样本相当(0.86 vs. 0.84),但特异度更高(0.92 vs. 0.81)。酶联免疫斑点法(enzyme linked immunospot assay,ELISPOT)检测特异度优于酶联免疫吸附试验(enzyme-linked immunosorbent assay,ELISA)(0.86和0.81)。针对结核性胸膜炎,胸腔积液ELISPOT检测的AUC值为0.972,优于血液检测(AUC=0.909)。血液ELISPOT检测在淋巴结结核亚组中显现出良好诊断效能(AUC=0.936)。IGRA对骨关节结核的诊断价值有限(AUC=0.7343)。结论: IGRA是诊断EPTB的有效辅助工具,但检测性能取决于标本类型和检测方法。证据支持对疑似结核性胸膜炎患者优先使用胸腔积液ELISPOT检测,对淋巴结结核优先使用血液ELISPOT检测。骨关节结核诊断中应谨慎解读IGRA结果。

Abstract:

Objective: To systematically evaluate the diagnostic accuracy of interferon-γ release assays (IGRA) for extrapulmonary tuberculosis (EPTB) in adults across different specimen types and assay methods, and to provide evidence-based guidance for optimizing clinical diagnostic pathways. Methods: A systematic search was conducted across PubMed, Web of Science, and the Cochrane Library databases from January 2014 to May 2025, to identify studies comparing the diagnostic accuracy of commercial IGRA (T-SPOT.TB or QuantiFERON-TB Gold series) with composite reference standards (culture and/or clinical diagnosis). Bivariate random effect models were used to combine sensitivity and specificity, and subgroup analyses (specimen type, detection method, disease type, etc.) and meta-regression were conducted. Results: A total of 28 studies (32573 participants) were included. The overall pooled sensitivity, specificity, and area under curve (AUC) values were 0.83 (95%CI: 0.79-0.87), 0.86 (95%CI: 0.82-0.90), and 0.9089, respectively. The sensitivity of IGRA for detecting body fluid samples was comparable to that of blood samples (0.86 vs. 0.84), but the specificity was higher (0.92 vs. 0.81). The enzyme-linked immunospot assay (ELISPOT) demonstrated superior specificity compared to the enzyme-linked immunosorbent assay (ELISA)(0.86 vs. 0.81). For tuberculous pleurisy, the AUC value of pleural effusion ELISPOT detection was 0.972, which was superior to that of blood detection (AUC=0.909). Blood ELISPOT detection showed good diagnostic performance in the lymph node tuberculosis subgroup (AUC=0.936). IGRA had limited diagnostic value for osteoarticular tuberculosis (AUC=0.734). Conclusion: IGRA is an effective auxiliary tool for diagnosing EPTB, but its detection performance depends on the type of specimen and the detection method. Evidence suggests that for patients suspected of having tuberculous pleurisy, pleural effusion ELISPOT testing should be prioritized, while for lymph node tuberculosis, blood ELISPOT testing should be preferred. In the diagnosis of osteoarticular tuberculosis, IGRA results should be interpreted with caution.
