STATA software was used to evaluate the differences in focal absorption rate, the time to cough symptom remission, sputum culture-negative rate, CD3+ T, CD4+ T, and CD8+ T cell levels after treatment.Results: A total of 23 randomized controlled trials literature involving 2031 cases were included. Meta-analysis revealed that compared with conventional therapy, the sputum culture-negative rate was significantly increased after 2– 3 months and 6– 9 months of treatment and the whole course of combined thymopentin treatment. The risk ratio (RR, 95% CI) was 1.44 (1.26– 1.64), 1.47 (1.21– 1.78), and 1.27 (1.18– 1.36), respectively. In the combined thymopentin treatment group, the focal absorption rate was higher, with RR (95% CI) = 1.36 (1.25– 1.47), the time of cough remission was shortened, with WMD (95% CI) =− 9.46d (− 10.36,− 8.57) and the differences were all statistically significant. Combined thymopentin therapy could effectively improve the levels of CD3+ T and CD4+ T lymphocytes in patients with drug-resistant PTB after 2– 3 months, 6– 9 months of treatment. The WMD (95% CI) were 9.96% (7.84, 12.08), 4.68% (2.90, 6.47) and 10.26% (7.81, 12.71), 7.21% (6.28, 8.15), respectively, and could also reduce the level of CD8+ T lymphocytes after 2– 3 months and 6– 9 months of treatment. The WMD (95% CI) were − 4.06% (− 4.96, − 3.13), − 3.52%, (− 4.07,− 2.98), respectively, and the differences were all statistically significant.Conclusion: Thymopentin adjuvant treatment for drug-resistant PTB can promote the therapeutic effect and improve the immune indexes in patients with drug-resistant PTB.Keywords: thymopentin, drug resistance, pulmonary TB, immunity, meta-analysis |
