Probiotics in pediatric functional abdominal pain disorders: a systematic review and meta-analysis
Abstract
Functional abdominal pain disorders (FAPDs), currently referred to as abdominal pain-related disorders of gut-brain interaction (AP-DGBIs), are characterized by recurrent abdominal discomfort in children that cannot be fully explained by an identifiable organic disorder. Probiotics are increasingly used as microbiota-targeted treatments, although their true clinical benefit remains uncertain. The objective of this study is to evaluate the efficacy and safety of probiotic supplementation compared with placebo in children with AP-DGBIs. PubMed, Embase, Web of Science and Scopus were searched from the start of each database to April 2026; the review followed PRISMA guidelines. Randomized controlled trials in patients < 18 years with FAPDs (IBS, FAP-NOS, functional dyspepsia, abdominal migraine) diagnosed by Rome II-IV, in which probiotic supplementation was evaluated. Two reviewers independently extracted data and assessed risk of bias using RoB2 tool. Meta-analyses and network meta-analyses were used to synthesize the data; the certainty of the evidence was evaluated using GRADE and CINeMA. This review covers 21 trials (2005-2025) with 1899 patients treatments completed. Probiotics modestly reduced pain intensity and weekly pain episodes, and modestly increased the rate of complete symptom resolution compared with placebo. Treatment with probiotics was associated with complete symptom resolution in 35.3% versus 22.8% of placebo-treated patients, corresponding to a number…
