Crohn's Disease Exclusion Diet Plus Partial Enteral Nutrition Induces Sustained Remission in a Randomized Controlled Trial (CDED)

Summary Excerpt: CDED plus PEN was better tolerated than EEN in children with mild to moderate CD. Both diets were effective in inducing remission by week 6. The combination CDED plus PEN induced sustained remission in a significantly higher proportion of patients than EEN, and produced changes in the fecal microbiome associated with remission. These data support use of CDED plus PEN to induce remission in children with CD.

Nutritional Therapy in Pediatric Crohn Disease: the Specific Carbohydrate Diet. (SCD)

Summary Excerpt: This chart review suggests that the SCD and other low complex carbohydrate diets may be possible therapeutic options for pediatric Crohn disease. Further prospective studies are required to fully assess the safety and efficacy of the SCD, or any other low complex SCDs in pediatric patients with Crohn disease.

Exclusive Enteral Nutrition Provides an Effective Bridge to Safer Interval Elective Surgery for Adults With Crohn's Disease (EEN)

Summary Excerpt: Exclusive enteral nutrition frequently down-stages the need for surgery in patients presenting with stricturing or penetrating complications of Crohn's disease; it is associated with a reduction in systemic inflammation, operative times and the incidence of post-operative abscess or anastomotic leak.

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)

Summary Excerpt: 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.

The Specific Carbohydrate Diet for Inflammatory Bowel Disease: A Case Series (SCD)

Summary Excerpt: Our survey results suggest that SCD can potentially be an effective tool in the management of some patients with IBD and specifically in patients with colonic and ileocolonic CD who made up the majority of our study group. A highly educated group of patients follow the SCD; all but one of the adults in our study had a college or graduate degree. Our results also suggest that in some patients with moderate to severe disease who follow this diet, discontinuation of immunosuppressive agents has been feasible.

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).
