Abstract

Abstract:

Objective:To evaluate the clinical effectiveness and safety of interferon-γ(IFN-γ) combined with anti-tuberculosis drugs in treating pulmonary tuberculosis (PTB) through Meta-analysis and to provide reliable evidence for using IFN-γ in the treatment of PTB. Methods:Searching PubMed, Embase, Chinese Bio Medical Literature Database (CBM), China Knowledge Network (CNKI), and Wanfang Database, the publicly published clinical randomized controlled trials (RCTs) in the treatment of PTB using IFN-γ combined with anti-tuberculosis drugs were included. According to the Cochrane manual, Review Manager 5.4 software was used to evaluate the quality of those included papers. All the studies were analyzed with STATA 12.0 software, patients treated with IFN-γ combined with anti-tuberculosis drugs were regarded as the observation group, while patients treated only with anti-tuberculosis drugs were regarded as the control group. The evaluation indicators included the absorption rate of lung lesions, the closure rate of cavities, the sputum negative conversion rate after 2-3 months’ and 6-9 months’ treatment, and the percentage of CD4⁺T cell and the CD8⁺T cell in peripheral blood after treatment. Results:Eighteen RCT studies with a total of 1341 patients were included. The Meta-analysis showed that compared with the control group, after 2-3 months’ and 6-9 months’ treatment, the RR (95%CI) of sputum negative conversion rate of the observation group were 1.40 (1.26-1.56) and 1.41 (1.12-1.76), respectively; the RR (95%CI) of lesion absorption rate were 1.43 (1.09-1.88) and 2.84 (1.65-5.00), respectively; the RR (95%CI) of cavity closure rate were 2.07 (1.47-2.92) and 1.56 (1.28-1.91), respectively. These indicators were all significantly increased in the observation group (Ps<0.05). Comparing the observation group with the control group, the percentage of peripheral blood CD4⁺ T cells was significantly increased (P<0.05), and the percentage of CD8⁺ T cells was significantly decreased (P<0.05), the WMD (95%CI) were 5.18 (2.53-7.84) and -3.16 (-6.08--0.23), respectively. The RR (95%CI) of side effect incidence was 1.07 (0.72-1.60), RR (95%CI) of abnormal liver function, skin allergy, and gastrointestinal reactions were 1.02 (0.95-1.11), 1.03 (0.95-1.11) and 1.01 (0.93-1.11), respectively. All differences were not statistically significant (Ps>0.05). Conclusion:IFN-γ combined with anti-tuberculosis drugs in treating PTB can promote the absorption of lung lesions, the closure of cavities, the negative conversion of sputum, and meanwhile improve the immunological indicators of PTB patients.
