Dietary adherence to the Mediterranean diet pattern in a randomized clinical trial of patients with quiescent ulcerative colitis (MED)

NTforIBD Comment: Newsletter March 2023

Summary Excerpt: Patients with UC can adhere to and tolerate the Mediterranean Diet Pattern (MDP) and achieve improved diet quality with reduced bowel symptoms compared to Canadian Habitual Diet (CHD). Increased adherence to the MDP can be achieved through appropriate support such as nutrition education and counseling by a Registered Dietitian. Overall, this data supports that the MDP can be recommended as a remission diet to UC patients to help support disease management alongside front-line therapy drugs.

P499 Exclusive enteral nutrition induces transmural healing in adults with active Crohn’s disease (EEN)

Summary Excerpt: EEN was identified to induce early transmural response and healing in patients with active CD. Further studies are required to evaluate the capacity for EEN to induce transmural healing and the role of IUS as an early assessment tool in monitoring therapeutic response in CD.

Apr 2016 Specific Carbohydrate Diet for Pediatric Inflammatory Bowel Disease in Clinical Practice within an Academic IBD Center SCD Obih C et al This retrospective review provides evidence that the SCD can be integrated into a tertiary care center and may improve clinical and laboratory parameters for pediatric patients with nonstructuring, nonpenetrating CD as well as UC. Further prospective studies are needed to fully assess the safety and efficacy of the SCD in pediatric patients with IBD. Nutrition. 2016 Apr;32(4):418-25. doi: 10.1016/j.nut.2015.08.025. Epub 2015 Nov 30.
Nov 2016 Patients Perceive Clinical Benefit with the Specific Carbohydrate Diet for Inflammatory Bowel Disease SCD Suskind DL et al Individuals perceived clinical improvement on the SCD. Four percent reported clinical remission prior to the SCD, while 33 % reported remission at 2 months after initiation of the SCD, and 42 % at both 6 and 12 months. For those reporting clinical remission, 13 % reported time to achieve remission of less than 2 weeks, 17 % reported 2 weeks to a month, 36 % reported 1-3 months, and 34 % reported greater than 3 months. For individuals who reported reaching remission, 47 % of individuals reported associated improvement in abnormal laboratory values. Dig Dis Sci. 2016 Nov;61(11):3255-3260. Epub 2016 Sep 16
Mar 2017 Exclusive Enteral Nutrition Provides an Effective Bridge to Safer Interval Elective Surgery for Adults With Crohn's Disease EEN Heerasing N et al 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. Aliment Pharmacol Ther , 45 (5), 660-669 Mar 2017
Sep 2017 Efficacy of Exclusive Enteral Nutrition in Complicated Crohn's Disease EEN Yang Q et al EEN is effective in inducing early clinical remission, mucosal healing, promoting fistula closure and reducing the size of abscess in adult CD patients with complications. Scand J Gastroenterol , 52 (9), 995-1001 Sep 2017
Sep 2017 Lack of Mucosal Healing From Modified Specific Carbohydrate Diet in Pediatric Patients With Crohn Disease mSCD Wahbeh GT et al All subjects reported no active symptoms before repeat endoscopic evaluation on mSCD, the majority had consistently normal C-reactive protein, albumin and hematocrit assessments, and mildly elevated fecal calprotectin (>50 μg/g, median 201, range 65-312) at any point within 3 months before the repeat endoscopy. One patient showed complete ileocolonic healing but persistent upper gastrointestinal tract ulceration. Complete macroscopic mucosal healing of both the ileocolon and upper gastrointestinal tract was not seen in any patient.

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.

Oct 2017 Dietary Therapy With the Crohn's Disease Exclusion Diet Is a Successful Strategy for Induction of Remission in Children and Adults Failing Biological Therapy CDED Sigall-Boneh RS et al Dietary treatment combining PEN with the CDED may be a useful salvage regimen for patients failing biological therapy despite dose escalation.

Oct 2017 Diet to the Rescue: Cessation of Pharmacotherapy After Initiation of Exclusive Enteral Nutrition (EEN) Followed by Strict and Liberalized Specific Carbohydrate Diet (SCD) in Crohn's Disease EEN, SCD Nakayuenyongsuk W et al NA Dig Dis Sci. 2017 Oct;62(10):2686-2689. doi: 10.1007/s10620-016-4446-1.
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.

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.

Nov 2017 Nutritional Adequacy of the Specific Carbohydrate Diet in Pediatric Inflammatory Bowel Disease SCD Braly K et al Nutrient intake of pediatric inflammatory bowel disease patients on the SCD was adequate when compared with a healthy peer reference population, but adequacy was variable when compared with the dietary recommended intakes. Close monitoring with a multidisciplinary team for patients using the SCD as an alternative or adjunct therapy is recommend to ensure positive outcomes for overall patient health. J Pediatr Gastroenterol Nutr. 2017 Nov;65(5):533-538. doi: 10.1097/MPG.0000000000001613.
