Meta-analysis and trial sequential analysis of Qingjin Huatan Decoction for treating community-acquired pneumonia in elderly / 中国中药杂志

To systematically evaluate the clinical efficacy and safety of modified Qingjin Huatan Decoction in the treatment of community-acquired pneumonia in the elderly, and provide evidence-based reference for the clinical application of this prescription. Randomized controlled trials of Qingjin Huatan Decoction in the treatment of community-acquired pneumonia in the elderly were collected by searching PubMed, EMbase, Cochrane Library, CNKI, China Biomedical Literature database, VIP database and WanFang database. Outcome indicators included clinical effective rate, inflammation index, symptom improvement time, chest radiograph improvement time, hospitalization time and adverse reactions. RevMan 5.3 and Stata/IC 15.1 software were used for Meta-analysis; TSA 0.9.5.10 Beta software was used for trial sequential analysis, and GRADE profiler 3.6 was used for grade evidence quality evaluation. Thirteen studies were included finally, including 1 058 patients, 536 patients in the experimental group and 522 patients in the control group.Meta-analysis showed that, the clinical effective rate of the experimental group was significantly higher than that of the control group(RR=1.16, 95%CI[1.10, 1.21], P<0.000 01); fever time(MD=-1.32, 95%CI[-1.93,-0.71], P<0.000 1), cough time(MD=-1.95, 95%CI[-2.69,-1.21), P<0.000 01), time to rale disappearance(MD=-1.55, 95%CI[-2.37,-0.73], P=0.000 2), time to chest radiograph improvement(MD=-1.72, 95%CI[-2.98,-0.46], P=0.007), and hospitalization time(MD=-3.16, 95%CI[-4.58,-1.74], P<0.000 01) in the experimental group were significantly shorter than those in the control group. The improvement in CRP(WMD=-3.44,95%CI[-4.50,-2.38],P<0.001), WBC(WMD=-2.04,95%CI[-3.31,-0.78],P<0.01), IL-6(WMD=-4.27,95%CI[-4.62,-3.92],P<0.001), and TNF-α(WMD=-0.47,95%CI[-0.55,-0.39], P<0.001) of the experimental group was significantly better than that of the control group. There was no significant difference in PCT improvement between the two groups(WMD=-0.63, 95%CI[-1.65, 0.40], P=0.23). No serious adverse reactions occurred in both groups. Sequential analysis of the trial showed that in the studies with cumulative inclusion of clinical effective rate, the data passed the traditional threshold and TSA threshold, further confirming its clinical efficacy. GRADE evaluation showed that the evidence level was low to extremely low. Western medicine treatment combined with Qingjin Huatan Decoction may improve clinical efficiency in the treatment of community-acquired pneumonia in the elderly, improve clinical symptoms faster, reduce CRP, WBC and other inflammatory indicators, and shorten hospital stay. The level of evidence obtained in this study is low, which needs to be further verified by high-quality multi-center, randomized controlled trials.
