Abstract

Introduction: It is widely accepted that inflammatory responses play a key role in acute pancreatitis (AP). We conducted a systematic review and meta-analysis to determine the effect of QingYi decoction on inflammatory markers.

Methods: The PubMed, EMBASE, Cochrane, CNKI, CBM, and WANFGANG databases were searched for randomized controlled trials published before December 2019. Thirty-nine eligible studies were included in the meta-analysis. The quality of the included studies was assessed using the Cochrane Collaboration risk of bias tool. The standardized mean differences (SMDs) with corresponding 95% CIs were examined for inflammatory markers. The chi-square test and I² statistic were used to assess heterogeneity. We assessed publication bias by Begg's test, Egger's test, and the trim and fill method. In addition, a meta-regression, sensitivity analysis, subgroup analysis, and cumulative meta-analysis were performed to assess the effects of confounding factors. The quality of evidence was evaluated by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.

Results: The pooled effect estimate indicated that QingYi decoction treatment significantly reduced the levels of pro-inflammatory IL-6 (SMD = -3.33; 95% CI, -4.17, -2.50; p < 0.001; I²: 97.9%), IL-8 (SMD = -1.55; 95% CI, -2.03, -1.07; p < 0.001; I²: 96.1%), TNF-α (SMD = -1.04; 95% CI, -1.37, -0.72; p < 0.001; I²: 93.9%), IL-1 (SMD = -2.05; 95% CI, -3.21, -0.90; p < 0.001; I²: 93.4%), and IL-1β (SMD = -1.31; 95% CI, -2.42, -0.21; p < 0.001; I²: 89.8%) and elevated the levels of anti-inflammatory IL-10 (SMD = 0.99; 95% CI, 0.60, 1.38; p < 0.001; I²: 91.1%) among patients with AP.

Conclusion: The current review and meta-analysis suggest that the therapeutic effect of QingYi decoction may be related to its anti-inflammatory properties. Due to the high heterogeneity across the included studies, additional large-scale and rigorously designed studies are needed to confirm the conclusions of this study.
