Elimination of Fermentable Carbohydrates to Reduce Gastrointestinal Symptoms in Pediatric Patients With Irritable Bowel Syndrome: A Narrative Review

How to manage irritable bowel syndrome in children

AIM

This paper discusses the risk factors and management of paediatric irritable bowel syndrome (IBS), with a focus on the role of the gastrointestinal microbiome.

METHODS

English articles of interest published in PubMed and Google Scholar were searched using subject heading and keywords of interest.

RESULTS

Only few randomised controlled trials on the management of IBS in children have been published. The vast majority of these intervention trials target to change the composition of the gastrointestinal microbiome. Most studies are underpowered. Major heterogeneities in study designs such as differences in inclusion criteria, including patients with different pain-related functional gastrointestinal disorders and differences in primary outcomes, make it impossible to formulate recommendations. Overall, few adverse events are reported what could indicate safety or point to suboptimal conduction of clinical trials and safety reporting. However, it can also not be excluded that some interventions such as the administration of selected probiotic products may result in benefit.

CONCLUSION

There is insufficient evidence to recommend any therapeutic intervention in paediatric IBS, including manipulation of the gastrointestinal tract microbiome, despite the evidence that dysbiosis seems an associated pathophysiologic factor. More designed prospective trials are needed since IBS is not a rare condition during childhood.
