A systematic review and meta-analysis of acupoint application combined with western medicine therapy in the treatment of bronchial asthma.

BACKGROUND:This study aimed to evaluate and compare the efficacy and safety of acupoint application therapy (AAT) with conventional western medicine therapy (CWMT) and CWMT in the treatment of bronchial asthma. Since there are several researches reporting AAT with CWMT for bronchial asthma and there is little comprehensive analysis on this topic, we conducted this research. METHODS:Randomized controlled trials on the use of AAT with CWMT in the treatment of bronchial asthma published between 2009 and 2020 were retrieved from the PubMed, Embase, Cochrane Library, and CNKI (Chinese National Knowledge Institute) databases. Studies meeting the inclusion criteria were selected for meta-analysis. Forest plot, sensitivity analysis and publication bias assessment were carried out in this article. RESULTS:Eight studies involving 1,520 patients were included in the meta-analysis. The clinical effect of AAT with CWMT in the treatment of asthma was superior to that of CWMT [mean difference (MD) =2.66 with 95% confidential interval (CI) (2.03, 3.49); overall effect P value <0.00001 and I2=89%]. There was no difference in adverse events between AAT with CWMT and CWMT [odds ratio (OR) =1.45; 95% CI: 0.62, 3.39; I2=0% and P of overall effect =0.4]. CWMT had higher ineffectiveness rate than AAT with CWMT (OR =0.29; 95% CI: 0.22, 0.38; P=0.33; I2=13%). According to the statistical analysis results, the AAT with CWMT group had higher overall effectiveness rate than the CWMT group (OR =0.29; 95% CI: 0.22, 0.38; P=0.33, fixed-effects model), with low heterogeneity (P=0.29; I2=13%). DISCUSSION:AAT with CWMT has a superior clinical effect to CWMT in patients with asthma, and there is no difference in adverse events between the two treatments. Therefore, AAT with CWMT should be promoted as a treatment for bronchial asthma.
