Exclusive Enteral Nutrition and Corticosteroids Therapy in Crohn's Disease (EENCD) (EENCD)

August 31, 2020 updated by: Maria Ines Pinto Sanchez, McMaster University

Synergistic Effect of Exclusive Enteral Nutrition Formula in Addition to Corticosteroids Therapy to Induce Clinical Remission in Patients With Crohn's Disease: a Pilot Study Involving a Multidimensional Assessment of Potential Mechanisms

This study evaluates the effect of Exclusive Enteral Nutrition (EEN) in addition to different regimes of corticosteroid (CS) therapy (Prednisone) compared to CS alone in adults participants with active Crohn's Disease, on symptoms and inflammation after 6 weeks of treatment. Participants will be randomized to three treatment arms: standard CS, standard CS with EEN, short course CS with EEN. Participants will be assessed through questionnaires for gut symptoms, quality of life, mood changes and dietary patterns and potential mechanisms will be investigated by collecting stool samples for characterization of gut bacterial profiles, collection of blood to determine inflammatory markers and evaluation of gut motility before and after treatment. The investigators hypothesize that six weeks of EEN with CS will be more effective than CS alone in inducing clinical remission in patients with active CD, as well as leading to beneficial changes in the composition and/or metabolic activity of the intestinal microbiota, gastrointestinal transit and inflammatory burden. Furthermore, six weeks of EEN in addition to a short course of CS will have similar efficacy than EEN with standard course of CS and reduced number of adverse events.

Detailed Description

Crohn's disease (CD) is an inflammatory bowel disease (IBD) characterized by diarrhea, abdominal pain and bleeding. There are several treatment options but the most-widely used for acute therapy are corticosteroids (CS), however, CS are often associated with severe side effects. The administration of a formula for exclusive feeding (EEN) is well-established as an alternative to CS in children with Crohn's disease (CD). EEN has been proposed to reduce inflammation in the gut. However, this intervention is not routinely used in adults, in part because of uncertainty regarding the magnitude of the benefit of EEN reported in previous studies. Although few studies have examined the effects of EEN in adult patients with active CD, the potentially synergistic effects of adding EEN to the conventional CS was not explored. Furthermore, it is also possible that the addition of EEN allows to decrease the duration of CS therapy; however, this was not investigated before.

The investigators propose that an oral formula may help decrease gut inflammation and improve nutritional status through modulation of gut bacteria. The investigators will therefore evaluate the effect of exclusive formula feeding therapy in addition to different regimes of CS therapy compared to CS alone in adult patients with active CD, on symptoms and inflammation after 6 weeks of treatment. Participants will be randomized to three treatment arms: standard CS, standard CS with EEN, short course CS with EEN. The investigators will collect information through questionnaires that assess gut symptoms, quality of life, mood changes and dietary patterns. To investigate potential mechanisms, the investigators will collect stool samples to characterize gut bacterial profiles, blood to determine inflammatory markers and evaluate gut movements (motility) before, and after the treatment. The investigators hope that the results will lead to better understanding of the beneficial effect of exclusive formula feeding in addition to CS as a more efficacious alternative than CS alone, and to understand the mechanisms of this therapy.
