Abstract:

Objective To evaluate the diagnostic value of metagenomic next-generation sequencing (mNGS) technology in different clinical specimens for pulmonary tuberculosis (PTB). Methods Relevant researches on the diagnosis of PTB by using mNGS included in PubMed, Embase, The Cochrane Library, CNKI, Wanfang and Vip and other databases for published from the establishment to November 2022were searched. After strict screening and quality evaluation, the literatures were screened by two researchers independently, followed by data extraction and risk assessment of inclusion study bias. StataSE16 software and Revman5.3 software were used for meta-analysis. Results A total of 11 eligible literature and 1995 patients were included in the meta-analysis. The results showed that the sensitivity and specificity of mNGS for PTB diagnosis in lung specimens was 70% (95% CI: 58%-79%) and 99% (95% CI: 98%-100%), positive likelihood ratio (PLR) was 106.9 (95% CI: 31.1-366.6), negative likelihood ratio(NLR) was 0.31 (95% CI: 0.21-0.43), diagnostic odds ratio(DOR) was 350 (95% CI: 81-1512) and the area under curve(AUC) was 0.97. The sensitivity, specificity, PLR, NLR, DOR, and AUC of mNGS for PTB diagnosis in bronchoalveolar lavage fluid (BALF) were 71% (95% CI: 55%-83%), 99% (95% CI: 97%-100%), 76.4 (95% CI: 26.6-218.9), 0.30 (95% CI: 0.18-0.48), 258 (95% CI: 75-895), and 0.99, respectively. The sensitivity and specificity of mNGS for PTB diagnosis in lung tissues were 81% (95% CI: 69%-89%) and 97% (95% CI: 88%-99%), PLR was 26.0 (95% CI: 6.6-102.4), NLR was 0.19 (95% CI: 0.11-0.33), DOR was 135 (95%CI: 29-639), and AUC was 0.97. Conclusion Application of mNGS technology exerts high diagnostic value for PTB, especially for sputum-negative PTB, which can be used as an auxiliary tool for rapid diagnosis of PTB.
