摘要:

目的: 探讨宏基因组二代测序(metagenomics next-generation sequencing,mNGS)技术在疑似骨关节结核患者中的诊断价值。方法: 回顾性分析2019年1月至2023年1月在首都医科大学附属北京胸科医院就诊的疑似骨关节结核患者176例(包括57例骨关节结核患者和119例非结核性骨关节疾病患者),所有研究对象同时行BACTEC MGIT 960液体培养(简称“MGIT 960培养”)、GeneXpert MTB/RIF检测(简称“Xpert”检测)和mNGS检测。分析三种检测方法的阳性预测值、阴性预测值、敏感度及特异度。结果: mNGS检测疑似骨关节结核患者病灶标本结果中,化脓性细菌80例(45.5%)、分枝杆菌73例(41.5%)、真菌22例(12.5%)、放线菌1例(0.6%)。73例分枝杆菌中结核分枝杆菌57例,占32.4%。mNGS、Xpert和MGIT 960培养阳性预测值分别为87.7%(95%CI:77.6%~93.7%)、100.0%(95%CI:93.5%~100.0%)、100.0%(95%CI:89.4%~100.0%),mNGS、Xpert和MGIT 960培养的阴性预测值分别为94.1%(95%CI:88.9%~97.0%)、98.3%(95%CI:93.8%~99.6%)和83.2%(95%CI:78.5%~87.1%)。mNGS与Xpert 检测的敏感度分别为87.7%(95%CI:76.3%~94.9%)、96.5%(95%CI:87.9%~99.6%),高于MGIT 960培养[57.9%(95%CI:44.1%~70.9%)]。mNGS、Xpert和MGIT 960培养的特异度分别为94.1%(95%CI:88.3%~97.6%)、100.0%(95%CI:96.9%~100.0%)、100.0%(95%CI:96.9%~100.0%)。结论: mNGS在疑似骨关节结核患者中具有较高的诊断价值。

Abstract:

Objective: To explore the diagnostic value of metagenomic next-generation sequencing (mNGS) in patients with suspected osteoarticular tuberculosis. Methods: Retrospective analysis was conducted on data of 176 suspected osteoarticular tuberculosis patients (including 57 patients with osteoarticular tuberculosis and 119 patients with non-tuberculous osteoarticular disease) admitted to Beijing Chest Hospital, Capital Medical University from January 2019 to January 2023. Samples of all subjects were simultaneously subjected to BACTEC MGIT 960 liquid culture (referred to as “MGIT 960 culture”), GeneXpert MTB/RIF detection (referred to as “Xpert” detection) and mNGS detection, then positive predictive value, negative predictive value, sensitivity and specificity of those three methods were analyzed. Results: Results of mNGS detection showed that 80 cases (45.5%) were infected with purulent bacteria, 73 cases (41.5%) with mycobacteria, 22 cases (12.5%) with fungi, and 1 case (0.6%) with actinomyces. Among the 73 mycobacteria cases, 57 (32.4%) were Mycobacterium tuberculosis. The positive predictive values of mNGS, Xpert and MGIT 960 culture were 87.7% (95%CI: 77.6%-93.7%), 100.0% (95%CI: 93.5%-100.0%), 100.0% (95%CI: 89.4%-100.0%), respectively, while their negative predictive values were 94.1% (95%CI: 88.9%-97.0%), 98.3% (95%CI: 93.8%-99.6%) and 83.2%(95%CI:78.5%-87.1%), respectively. The sensitivities of mNGS and Xpert were 87.7% (95%CI: 76.3%-94.9%) and 96.5% (95%CI: 87.9%-99.6%), respectively, higher than those of MGIT 960 culture (57.9%, 95%CI: 44.1%-70.9%). The specificities of mNGS, Xpert and MGIT 960 cultures were 94.1% (95%CI: 88.3%-97.6%), 100.0% (95%CI: 96.9%-100.0%) and 100.0% (95%CI: 96.9%-100.0%), respectively. Conclusion: mNGS has a high diagnostic value in patients with suspected osteoarticular tuberculosis.
