Successful Dietary Therapy in Paediatric Crohn's Disease is Associated with Shifts in Bacterial Dysbiosis and Inflammatory Metabotype Towards Healthy Controls (CDED)

NTforIBD Comment: October 2022 Newsletter

Summary Excerpt: Successful dietary therapy induced correction of both compositional and functional dysbiosis. However, 12 weeks of diet was not enough to achieve complete correction of dysbiosis.

Effect of the Crohn’s Disease Exclusion Diet (CDED) on the Fecal Calprotectin Level in Children with Active Crohn’s Disease (CDED)

NTforIBD Comment: October 2022 Newsletter

Summary Excerpt: In their conclusion, the authors wrote: “In the group under analysis, this nutritional intervention resulted in a significant decrease in FCP level and contributed to normalization of this parameter in one-third of patients, which is a similar or better result compared to pharmacological treatment.”

Date Title Diets Authors Summary Excerpt Citation
Jun 2021 Low-Fat, High-Fiber Diet Reduces Markers of Inflammation and Dysbiosis and Improves Quality of Life in Patients With Ulcerative Colitis Other Diets - UC Fritsch J et al In a cross-over study of patients with UC in remission, we found that a catered LFD or iSAD were each well tolerated and increased quality of life. However, the LFD decreased markers of inflammation and reduced intestinal dysbiosis in fecal samples. Dietary interventions therefore might benefit patients with UC in remission.

Mar 2022 Adherence to the Mediterranean Diet Improved Clinical Scores and Inflammatory Markers in Children with Active Inflammatory Bowel Disease: A Randomized Trial MED El Amrousy D, et al. Adherence to the Mediterranean diet improves clinical scores and inflammatory markers in children and adolescents with mild-moderate active IBD. J Inflamm Res. 2022;15:2075-2086. doi:10.2147/JIR.S349502
Feb 2018 Effect of the Specific Carbohydrate Diet on the Microbiome of a Primary Sclerosing Cholangitis and Ulcerative Colitis Patient SCD Dubrovsky A and Kitts CL Not only were substantial changes in the fecal bacterial composition detectable within two weeks, but all UC symptoms were also controlled as early as one week following the start of the diet. Cureus. 2018 Feb 9;10(2):e2177. doi: 10.7759/cureus.2177.
Sep 2017 Exclusive Enteral Nutrition Therapy in Paediatric Crohn's Disease Results in Long-term Avoidance of Corticosteroids: Results of a Propensity-score Matched Cohort Analysis EEN Connors J et al These findings suggest that EEN induction therapy is more effective in achieving early remission and is associated with long-term steroid avoidance without increased use of biologics or need for surgery. J Crohns Colitis , 11 (9), 1063-1070 2017 Sep 1
Oct 2014 Clinical and Mucosal Improvement with Specific Carbohydrate Diet in Pediatric Crohn Disease SCD Cohen SA et al Clinical and mucosal improvements were seen in children with CD, who used SCD for 12 and 52 weeks. In addition, CE can monitor mucosal improvement in treatment trials for pediatric CD. Further studies are critically needed to understand the mechanisms underlying SCD's effectiveness in children with CD. J Pediatr Gastroenterol Nutr. 2014 Oct;59(4):516-21. doi: 10.1097/MPG.0000000000000449.
Oct 2017 Effect of the Specific Carbohydrate Diet on Inflammatory Bowel Disease: A 5-Year Longitudinal Study SCD Chutkan R et al Our data confirms that the Specific Carbohydrate Diet is an effective long-term treatment for IBD that can result in improvement of symptoms, mucosal healing, and discontinuation of biologic and immunosuppressive medications. American Journal of Gastroenterology: October 2017 - Volume 112 - Issue - p S1479
Jan 2021 Multidimensional Impact of Mediterranean Diet on IBD Patients MED Chicco F et al A significant reduction of malnutrition-related parameters and liver steatosis was observed in both CD and UC patients after short-term dietary intervention based on the adoption of Md, and this was associated with a spontaneous improvement of disease activity and inflammatory markers. https://pubmed.ncbi.nlm.nih.gov/32440680/
Apr 2019 Relapse Prevention by Plant-Based Diet Incorporated into Induction Therapy for Ulcerative Colitis: A Single-Group Trial SVD Chiba M et al Relapse rates in UC after induction therapy with PBD were far lower than those previously reported with conventional therapy. Adherence to PBD was significantly higher than baseline even at 6-year follow-up. We conclude PBD is effective for preventing UC relapse. Perm J . 2019;23:18-220. doi: 10.7812/TPP/18-220.
Oct 2017 Induction with Infliximab and a Plant-Based Diet as First-Line (IPF) Therapy for Crohn Disease: A Single-Group Trial SVD Chiba M et al IPF therapy can induce remission in most patients with CD who are naïve to biologics regardless of age or whether they have a new diagnosis or relapse. Perm J . 2017;21:17-009. doi: 10.7812/TPP/17-009.
May 2010 Lifestyle-related Disease in Crohn’s Disease: Relapse Prevention by a Semi-vegetarian Diet SVD Chiba M et al Remission was maintained in 15 of 16 patients (94%) in the SVD group vs two of six (33%) in the omnivorous group. Remission rate with SVD was 100% at 1 year and 92% at 2 years. SVD showed significant prevention in the time to relapse compared to that in the omnivorous group (P = 0.0003, log rank test).

Oct 2019 An Autoimmune Protocol Diet Improves Patient-Reported Quality of Life in Inflammatory Bowel Disease AIP Chandrasekaran A et al Dietary modification can improve quality of life as early as week 3 in patients with active IBD. Larger randomized controlled trials are needed to examine dietary interventions in IBD. Crohn's & Colitis 360, Volume 1, Issue 3, October 2019, otz019,
Oct 2019 The Autoimmune Protocol Diet Modifies Intestinal RNA Expression in Inflammatory Bowel Disease AIP Chandrasekaran A et al Results from this RNA substudy would suggest dietary elimination, along with emphasis on a nutrient-dense diet, has the potential to positively modify inflammation and reduce symptoms in UC. Our substudy, though very small, included a well-defined subgroup of participants with UC on mesalamine only, avoiding effects that might be attributable to systemic or targeted immunosuppression.
