Safety and efficacy of S1P receptor modulators for the induction and maintenance phases in inflammatory bowel disease: A systematic review and meta-analysis of randomized controlled trials

Inflammatory bowel disease (IBD) is a chronic inflammatory condition that significantly affects quality of life. Conventional treatments have had limited success. this study evaluates the safety and efficacy of Sphingosine 1-phosphate receptor modulators (S1PrMs) as a potential treatment for IBD. We conducted a thorough search of published literature on PubMed, EMBASE, and Google Scholar from 2000 to 2023. The inclusion criteria were randomized controlled trials (RCTs) with a target population comprising of IBD patients receiving either S1PrMs or placebo and a comparison of the 2. The statistical analysis was conducted using RevMan (version 5.4). Forest plots presented the results as risk ratios (RR) with a 95% confidence interval. A total of 7 RCTs involving 2471 patients were included. The results were reported for both the induction and maintenance phases of treatment. in the induction phase, the intervention group proved to have a significantly higher incidence of histological remission (RR = 2.67; 95% CI [1.97, 3.60]; P
