Evaluation of the effect of probiotics on septic complications in patients with severe acute pancreatitis. A systematic review and meta-analysis.

Introduction: Severe acute pancreatitis (SAP) with major complications such as necrosis and multiple organ dysfunction syndrome (MODS) often leads to high mortality rates despite intensive treatment. Aim: To evaluate the effect of symbiotics (probiotics) on septic complications in patients with SAP. Material and methods: We searched the PubMed, Cochrane CENTRAL, SCOPUS, and Web of Science databases for relevant clinical trials and excluded observational studies. Quality appraisal was evaluated according to GRADE, and we assessed the risk of bias using Cochrane's risk of bias tool. We included the following outcomes: C-reactive protein (CRP), APACHE II score, hospital stay, multiorgan failure (MOF), systemic inflammatory response syndrome, infected pancreatic necrosis, septicaemia, need for operation, and death. We performed the analysis of homogeneous data under a fixed-effects model, while analysis of heterogeneous data were analysed under a random-effects model. We performed the analysis of dichotomous outcomes using the risk ratio (RR) and relative 95% confidence interval (CI). Results: We included a total of 7 clinical trials. We found that there was no significant difference between both groups regarding MOF (RR = 0.60 (0.25, 1.44), p = 0.26), septicaemia (RR = 0.66 (0.29, 1.50), p = 0.32), death (RR = 0.66 (0.19, 2.26), p = 0.51), infected pancreatic necrosis (RR = 0.50 (0.18, 1.38), p = 0.18), SIRS (RR = 0.81 (0.29, 2.23), p = 0.68), CRP, APACHE II score, and hospital stay. Conclusions: Contrary to some published trials, our meta-analysis concludes that the use of probiotics in patients with SAP is not effective in reducing the mortality rate, septic complications, and need for operation.
