Comparison of Quality of Life During a Flare of Crohn's Disease Treated With Prednisolone or aCDED With PEN in Adult Patients

Recruiting now · Phase 2

Conditions studied: Crohn Disease, Nutrition Assessment, Diet Therapy

In brief

Crohn's disease (CD), a type of inflammatory bowel disease (IBD), is on the rise globally. Although medical treatments have advanced, CD still leads to significant health issues due to disease progression and medication side effects. Exclusive enteral nutrition (EEN) is a recommended first-line treatment for pediatric CD, proving more effective than oral corticosteroids without side effects. However, EEN demands strict adherence, making it challenging for patients, particularly adults. In 2019, Levine et al. found that a combination of a specific diet (CD exclusion diet, CDED) and partial enteral nutrition (PEN) was as effective as EEN in inducing remission in pediatric patients, with better tolerance and adherence. CDED focuses on whole foods and aims to minimize harmful dietary components affecting the gut. In clinical practice, an adapted CDED (aCDED) has been used to provide more food choices, but it lacks validation in clinical trials. An aCDED that considers regional and seasonal food variations could enhance patient adherence and align with modern dietary preferences. This study aims to compare the quality of life during a flare up of Crohn's disease treated with standard of care or an adapted Crohn's disease exclusion diet with partial enteral nutrition in adult patients.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…
