Objective  To evaluate the efficacy and safety of meperizumab for patients with refractory asthma by means of meta-analysis. Methods  PubMed, Web of Science, China National Knowledge Infrastructure and other databases were searched for literatures on randomized controlled trials of meperizumab for patients with refractory asthma published before October 30, 2021. The Endnote X9.2 software was used to summarize and eliminate duplicate studies. The literature was screened according to the pre-specified inclusion and exclusion criteria, and data extraction and quality evaluation were performed on the selected literature. Stata 16.0 was used for meta-analysis. Results  A total of 632 related articles were detected, and 8 articles were included after screening, including 2438 subjects. Meta-analysis results showed that the patients with refractory asthma treated with meperizumab had a 22% reduction in the risk of exacerbation [relative risk (RR)=0.78, 95% confidence interval (CI) 0.70 to 0.88], forced expiratory volume in one second [weighted mean difference (WMD)=0.10, 95%CI 0.06 to 0.13] and asthma control questionnaire score (WMD=–0.32, 95%CI –0.47 to –0.17) were improved, blood eosinophil count (WMD=–0.23, 95%CI –0.37 to –0.09) and sputum eosinophil count (WMD=–6.37, 95%CI –9.68 to –3.06) were significantly decreased. The probability of serious adverse reactions was significantly reduced (RR=0.65, 95%CI 0.47 to 0.90). Conclusion  Meperizumab can effectively reduce the risk of exacerbation for asthma, improve lung function and asthma control level, reduce blood eosinophil count and sputum eosinophil count, and reduce the incidence of serious adverse reactions in patients with refractory asthma.
