Efficacy and safety of reduning injection for severe pneumonia: a systematic review and meta-analysis
Abstract
Objectives Reduning (RDN) injection is a traditional Chinese medicine (TCM) extract injection commonly used as an adjunct therapy for severe pneumonia (SP) in clinical practice in China; however, further validation is required. This study aims to systematically assess the efficacy and safety of RDN injection in treating SP. Methods The study was conducted using the data from CNKI, WanFang, VIP, SinoMed, PubMed, Embase, Cochrane Library, and Web of Science databases from their inception to 6 April 2024. We collected randomized controlled trials on the treatment of SP using RDN injection, and used Review Manager (version 5.3) for meta analysis. The primary outcomes was clinical efficacy. We used the Cochrane Risk of Bias Assessment Tool 2 (RoB 2) to assess the risk of bias for each study. Results A total of 1,897 patients with SP from 22 studies were included. The meta-analysis results showed that the combination of RDN injection and conventional treatment or antibiotic treatment for patients with SP was superior to traditional and antibiotic treatments alone in terms of clinical efficacy [risk ratio = 1.25%; 95% confidence interval (CI) (1.20, 1.30); p < 0.00001], fever reduction time [mean difference (MD) = −1.55 days; 95% CI (−1.91, −1.18); p < 0.00001], cough disappearance time [MD = −1.97 days; 95% CI (−2.63, −1.31); p < 0.00001], lung rales disappearance time [MD = −2.39 days; 95% CI (−3.09, −1.70); p < 0.00001], chest X-ray improvement time [MD = −2.73 days; 95% CI…
