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.

Dietetic advocacy for long-term use of exclusive enteral nutrition resulted in high-risk surgical avoidance for complicated fibrotic Crohn's disease – A case report (EEN)

NTforIBD Comment: NTforIBD newsletter 2023 Q2

Summary Excerpt: The first case report of long-term use of EEN in a patient with complicated fibrotic Crohn's disease. "This unique case is a wonderful example of dietetic advocacy and showcases the positive impact long-term EEN may have on surgical avoidance, clinical outcomes and self-reported Quality of Life."

Oct 2020 Effectiveness of Mediterranean Diet's Adherence in children with Inflammatory Bowel Diseases MED Strisciuglio C et al Children with IBD in remission have a sub-optimal food intake compared to HCs. MD seems to correlate to decreased intestinal inflammation. Nutrients . 2020 Oct 20;12(10):3206. doi: 10.3390/nu12103206.
Jan 2023 Effectiveness of partial enteral nutrition to treat adults with Crohn's Disease who lost response to biological therapy. PEN Nardone O. et al. For patients who lost response to biological therapy, the combination with PEN was associated with transmural response and clinical remission. Multiple failures to biologics were associated with adherence to PEN. Hence, the use of PEN dietary should be considered in difficult-to-treat patients Journal of Crohn's and Colitis, Volume 17, Issue Supplement_1, February 2023, Pages i717–i718,
May 2015 Efficacy of Concomitant Elemental Diet Therapy in Scheduled Infliximab Therapy in Patients With Crohn's Disease to Prevent Loss of Response EEN Kamata N et al Concomitant ED therapy is effective in maintaining scheduled IFX maintenance therapy in patients with luminal CD in order to prevent LOR.

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.

Feb 2021 Elemental Diet Therapy Plays a Significant Role in Preventing Surgical Recurrence of Crohn's Disease in the Era of Biologics PEN Shinozaki M et al Although univariate analyses revealed that all three treatment strategies had significant effects on surgical recurrence in patients with CD, multivariate analysis revealed that only ED therapy was significantly associated with surgical recurrence rates. Thus, ED therapy plays an important role in the management of CD, even in the era of biological therapies. Surg Today . 2021 Feb;51(2):250-257. doi: 10.1007/s00595-020-02112-5. Epub 2020 Aug 18.
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 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.

Dec 2017 Exclusive Enteral Nutrition versus Infliximab in Inducing Therapy of Pediatric Crohn’s Disease EEN Lou Y et al EEN provided similar improvements as IFX in clinical symptoms, mucosal healing, and BMI.

Jul 2023 Food for Thought: Remission of Perianal Pediatric Crohn’s Disease on Specific Carbohydrate Diet Monotherapy SCD Simon D, MD, et al.

Oct 2017 Induction with Infliximab and a Plant-Based Diet as First-Line (IPF) Therapy for Crohn Disease: A Single-Group Trial WFPB 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.

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.
