P0629 A scoping review of evidence-based dietary guidance and guidelines published by national and international organisations on Inflammatory Bowel Disease

Le résumé fourni par la source

Abstract Background Despite emerging evidence indicating the critical importance of diet interventions for induction and maintenance of remission of inflammatory bowel disease (IBD), we still lack consistent guidelines for diet recommendations and nutrition therapy. The aim of this in-depth scoping review was to identify evidence-based dietary guidance and clinical guidelines produced by national and international organisations on IBD and summarize their content for diet interventions to induce and maintain remission. Methods An extensive literature search was undertaken on PubMed (January ‘14 to November ‘24), including MeSH terms (“Inflammatory Bowel Disease” OR IBD OR Crohn’s OR Colitis) AND (diet OR diet* OR food OR nutrition OR nutr*) AND (guideline OR consensus OR “expert review” OR “topical review”). Eligible articles included evidence-based dietary guidance and clinical guidelines for adults living with IBD, produced by national and international organisations. Paediatric guidelines and articles not in English were excluded. Results 417 records were identified. After full-text review 10 papers fulfilled eligibility criteria. The eligible evidence-based dietary guidance and clinical guidelines were manuscripts produced by the European Crohn’s Colitis Organisation, International Organization For the Study of Inflammatory Bowel Disease, American Gastroenterological Association, European Society for Clinical Nutrition and Metabolism. Australasian society for parenteral and enteral nutrition, British Society of Gastroenterology, British Dietetic Association and the Dietitian Crohn’s Colitis Australian Network. Thirty different interventions were identified within different guidelines, proposed to induce and/or maintain remission for Crohn’s disease (CD) and/or ulcerative colitis. Exclusive enteral nutrition was recommended for induction of remission in CD by 9 out of 10 guideline articles. Similarly, CDED coupled with Partial Enteral Nutrition (PEN) was recommended for induction of remission in CD by 3 out of 10 guideline articles. Partial enteral nutrition was recommended for maintenance of remission in CD by 3 out of 10 guideline articles. Lastly, probiotic supplementation was recommended for induction of remission in UC by 2 out of 10 guideline articles. The remaining interventions were either recommended within a single guideline or there were inconsistent recommendations for their use between organisations. Conclusion The findings of this scoping review provide an overview of dietary guidelines by national and international professional organizations and can support collaboration between organizations worldwide thus reducing duplication of effort, facilitating reproducibility, and identifying guidance discrepancies.
