Dietary Modification In Inflammatory Bowel Disease Patients

May 27, 2025 updated by: University of Malaya

Dietary Modification In Patients With Inflammatory Bowel Diseases And Its Impact In Gut Microbiome

This research project aimed to develop a culturally appropriate Asian Inflammatory Bowel Disease Diet for the Malaysian population, based on the Crohn's disease exclusion diet (CDED). The study will be conducted in inflammatory bowel disease patients in University Malaya Medical Centre, which are ulcerative colitis and Crohn's disease patients. The objectives of this study are to assess the impact of diet in clinical outcome and gut microbiota changes in patients with inflammatory bowel disease (IBD). The study duration spans 24 weeks, during which comprehensive follow-ups will be conducted at 0, 6, 12, and 24 weeks, respectively. At each follow-up session, participants will be requested to provide stool and blood samples for meticulous assessment of clinical and biochemical responses.

Study Overview

Detailed Description

Inflammatory bowel disease is a chronic gut inflammation due to immune system dysregulation. Although the exact causes remain unknown, patients' dietary habits were shown to affect the disease activity depending on the food exposure, either proinflammatory or anti-inflammatory food. This randomized-controlled trial (RCT) study aims to improve the modified CDED diet that is acceptable for the Malaysian population at Universiti Malaya Medical Centre. This study comprised of three parts: (Part 1: In-depth interview to measure the acceptance of the diet, Part 2: Implementation of the CDED diet, Part 3: Identification of change in gut microbiome post dietary intervention). The duration of the study is two years.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To improve the Asian Inflammatory Bowel Disease diet.
Time Frame: 24 weeks
Implementing improvised dietary guidance based on CDED is suitable for Asian settings to see patients' adherence (%) based on the diet adherence rating scale questionnaire.
24 weeks
Number of Participants Achieving Clinical Response at Week 12
Time Frame: 12 weeks
Clinical response will be assessed based on Crohn's Disease Activity Index (CDAI) score. An improvement of clinical response is defined as <150 CDAI score at week 12.
12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Fecal Calprotectin Concentration from Baseline to Post-Intervention
Time Frame: 12 weeks
The effectiveness of the diet will be assessed by measuring fecal calprotectin concentration (mg/kg) at baseline and after the 12-week intervention.
12 weeks
Changes in Gut Microbiota Composition Over Time (Baseline, Week 6, Week 12, Week 24)
Time Frame: Baseline, Week 6, Week 12, Week 24
The gut microbiota composition of participants will be assessed at Baseline, Week 6, Week 12, and Week 24 using 16S rRNA sequencing and shotgun metagenomics. Changes in microbiota composition will be evaluated based on relative abundance (%) of bacterial taxa at the genus/species level.
Baseline, Week 6, Week 12, Week 24
Differential Distribution of Gut Microbiota Between Control and Intervention Groups at Weeks 6, 12, and 24
Time Frame: Week 6, Week 12, Week 24
The gut microbiota composition of participants following the Crohn's Disease Exclusion Diet (CDED) will be compared to those following the General Healthy Diet at multiple time points (Week 6, Week 12, and Week 24). Between-group differences will be evaluated based on relative abundance (%) of bacterial taxa at the genus/species level.
Week 6, Week 12, Week 24
