Prevalence of irritable bowel syndrome and functional abdominal pain disorders in children with inflammatory bowel disease in remission

Abstract

Abstract Despite evidence of an increased prevalence of irritable bowel syndrome (IBS) in adults with inflammatory bowel disease (IBD) compared with the general population, the prevalence of IBS in children with IBD is unclear. In this review, we aimed to identify the reported prevalence of IBS or functional abdominal pain disorders (FAPDs) in children with IBD in remission. A search of three databases (MEDLINE, Embase, and PubMed) was performed to identify studies reporting the prevalence of IBS or FAPDs in pediatric patients with IBD in remission. A total of 60 studies were identified, with four eligible studies remaining following abstract screening. In children with IBD in remission, the overall prevalence of IBS ranged between 3.9 and 16.1%, and the overall prevalence of FAPDs ranged between 9.6 and 29.5%. The prevalence of FAPDs in patients in biomarker‐based remission was generally higher than those in clinical remission (range 16–22.5% vs 9.6–16.7%, respectively). There is a paucity of literature reporting on the prevalence of IBS or FAPDs in children with IBD in remission. Despite the differences in criteria used to define IBD remission in the included articles, there seems to be an increased overall prevalence of IBS or FAPDs in children with IBD.
