Abstract:

Objective: The purpose of this study was to provide evidence for clinical treatment of multidrug-resistant pulmonary tuberculosis (MDR-PTB) by assessing the effectiveness and safety of using cycloserine (Cs)-containing anti-tuberculosis regimens in China. Methods: A search for “cycloserine”“multi-drug resistant pulmonary tuberculosis”“treatment effect” and “adverse effects” was conducted in database of China National Knowledge Infrastructure, Wanfang Data, VIP, China Biomedical Literature Service System, PubMed, Embase, and Cochrane Library for literature published from January 2011 to September 2022. Randomized controlled trials (RCT) of Cs-containing anti-tuberculosis regimens for the treatment of MDR-PTB in China were targeted. The literature was screened by two researchers and the Cochrane 5.1.0 bias risk assessment tool was used to evaluate the methodological quality of the included studies. Stata 17.0 MP software was used to analyze the outcome indicators. Results: A total of 35 included literature was divided into: Cs+conventional treatment compared with conventional treatment group, 1128 cases; thymosin+Cs+conventional treatment group compared with the conventional treatment group, 791 cases; Cs+conventional treatment group compared with para aminosalicylic acid+conventional treatment group, 433 cases; Cs+conventional treatment compared with ethambutol+conventional treatment, 419 cases. The results of Meta-analysis indicated that compared with conventional anti-tuberculosis treatment, Cs-containing regimens showed superior effectiveness in treating MDR-PTB (RR=2.191, 95%CI: 1.847-2.599), including the rate of sputum conversion (RR=2.002, 95%CI: 1.696-2.364), lesion absorption (RR=2.259, 95%CI: 1.836-2.779), and cavity shrinkage (RR=1.812, 95%CI: 1.482-2.217). The incidence of adverse reactions in mental and nervous system was higher in Cs-containing regimens (RR=1.696, 95%CI: 1.493-1.927). Conclusion: The results suggested that the Cs-containing regimens were more effective in treating MDR-PTB, but caution should be taken for adverse reactions in the central nervous system.
