Systematic evaluation and Meta-analysis on effectiveness and safety of Yupingfeng Granules on recurrent respiratory tract infection

Abstract

To evaluate the effectiveness and safety of Yupingfeng Granules in the treatment of recurrent respiratory tract infection.Six Chinese and English databases were retrieved,namely CNKI,Wan Fang,VIP,CBM,PubMed and Cochrane Library. Randomized controlled trials of Yupingfeng Granules in the treatment of recurrent respiratory tract infection were collected and screened. According to the evaluation criteria and tools of Cochrane,the heterogeneity among the studies was analyzed,and the Meta-analysis was carried out by Rev Man 5.3 software. A total of 16 studies were included in this study,with a total sample size of 1 788 cases,including 901 cases in the experimental group and 887 cases in the control group. Among them,11 intervention measures were Yupingfeng Granules combined with Western medicine routine vs routine Western medicine,and 5 research interventions were Yupingfeng Granules combined with pidomod vs pidomod based on routine therapy. Meta-analysis showed that the total effective rate of Yupingfeng Granules combined with Western medicine in the treatment of recurrent respiratory tract infection was better than that of Western medicine( RR= 1. 27,95%CI[1. 21,1. 34],P<0. 000 01). Based on the routine therapy,the total effective rate of Yupingfeng Granules combined with pidomod in the treatment of recurrent respiratory tract infection was better than that of pidomod( RR = 1. 23,95% CI[1. 13,1. 35],P<0. 000 01). A total of 21 cases of adverse events were reported in this study,including 6 cases in the experimental groups combined with traditional Yupingfeng Granules therapy and conventional Western medicine therapy and 15 in the control group. The adverse events were mainly gastrointestinal reactions,such as fatigue,nausea and diarrhea,which can tolerate or disappear with no impact on treatment. The incidence of adverse events in the two groups was not statistically significant( RR = 0. 44,95% CI[0. 19,1. 03],P = 0. 06). The results showed no significant difference in the incidence of adverse events between the two groups during treatment. Based on the routine therapy,no adverse event was reported in Yupingfeng Granules pidomod vs pidomod,indicating that both groups were safe. The analysis showed that Yupingfeng Granules combined with routine Western medicine therapy or combined with pidomod could increase the level of immunoglobulin and T lymphocytes in children. Based on the existing data and methods,Yupingfeng Granules combined with routine Western medicine therapy for recurrent respiratory tract infection can improve the total effective rate,immune function and body immunity,with no serious adverse reaction. However,because of the low quality of the literatures included in this study,it is still necessary to adopt well-designed large-sample clinical trials in conformity to international standards to improve the quality of evidence.
