Efficacy and safety of yinqiao powder combined with western medicine in the treatment of pneumonia: A systematic review and meta-analysis.


ABSTRACT:

Objective

This review aimed at systematically evaluating the efficacy and safety of Yinqiao powder combined with western medicine in the treatment of pneumonia.

Methods

A systematic search for randomized controlled trials (RCTs) focusing on pneumonia treatment using a combination of Yinqiao powder and western medicine was performed in PubMed, the Cochrane Library, EMBASE, Web of Science, CNKI, Wanfang, Weipu (VIP) and CBM. The retrieval time limit was from the establishment of the database to June 2020. Two researchers independently screened the literature, extracted the data and evaluated the bias risk of the included studies. A meta-analysis was performed using RevMan5.3 software. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

Result

Fifteen RCTs involving 1705 patients were included in the analysis. The meta-analysis results revealed the total effective rate of the treatment group [RR = 1.21, 95% CI (1.15, 1.27), P < 0.00001], bacterial clearance rate [RR = 1.13, 95% CI (1.05, 1.22), P = 0.001], adverse reactions [RR = 0.54, 95% CI (0.38, 0.76), P = 0.0005]. There were statistically significant differences in the cooling time, T cell number, procalcitonin (PCT) and C-reactive protein (CRP) value decline rate (P < 0.05). There was no statistically significant difference in the decline rate of neutrophils and leukocytes (P > 0.05).

Conclusion

The current evidence indicated that the Yinqiao powder combined with western medicine can improve total efficiency in the treatment of pneumonia patients. The combination therapy performed better when compared to western medicine alone in the cooling time, bacterial clearance rate, T cell count, decline rates of CRP and PCT as well as in the incidences of adverse reactions. However, there was no significant difference in the decline rates of neutrophils and leucocytes between the two groups. The funnel plot, Egger's test and Begg's test indicated publication bias, which may be associated with unpublished negative study results. Due to the limitation of the quality and quantity of the included studies, more high-quality studies should be performed to verify our conclusions.
