About this study

The purpose of this trial is to run a pilot study that examines the impact of different dietary components on risk factors such as the Genetic, Environmental, Microbial (GEM) Microbiome Risk Score (GMRS) and fecal calprotectin (FCP), a marker of inflammation in the bowels, and a risk factor for developing Crohn's disease (CD) among first degree relatives (parents, siblings, or offspring) of Crohn's patients. The study will utilize the Western diet and the Mediterranean diet to explore the complex interplay between diet, microbiome, and inflammatory biomarkers to identify specific dietary components that may be beneficial in reducing the risk of developing CD. The study will enroll 30 participants from Mount Sinai Hospital in Toronto.

Read the detailed description

This study is a clinical trial that will occur at Mount Sinai Hospital and healthy first degree relatives of CD patients will be recruited. Participation will occur over 7 weeks with 1 week of consuming the subject's regular diet and 6 weeks of intervention. A total of 30 subjects are expected to be enrolled into this trial. As part of this trial, The study will attempt to modify dietary consumption between the Western Diet (WD) and the Mediterranean Diet (MD) to evaluate participants responses to specific food items key to the WD or MD by monitoring subject's GMRS and FCP. Subjects will be randomized into one of two groups (1:1), in which there will be crossover between the two diets. Stool samples will be collected 3 times a week, a daily questionnaire and a daily consumption diary will be completed through an app.

Group 1 will follow the WD for weeks 2 and 3, switch to the MD for weeks 4 and 5, and then back to the WD for weeks 6 and 7. Group 2 will follow the MD for weeks 2 and 3, switch to the WD for weeks 4 and 5, and then back to the MD for weeks 6 and 7.

Meal plans developed by the study Dietitian and recipes will be provided for all weeks of the intervention (weeks 2-7). These meal plans will be identical for subjects within the same group. Groceries required to prepare the meals as per the meal plan will be provided to subjects on a weekly basis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Personalized model

    Repeated measures of FCP and GMRS will be used to generate a personalized model identifying food items that provide are predicted to have the greatest effect in the GMRS and FCP levels for a given individual

    Measured: 7 weeks

Secondary outcomes (5)
  1. Concentration of FCP levels over time during each intervention

    fecal calprotectin will be analyzed from all stool samples collected during the study to provide continual data on any changes in intestinal inflammation

    Measured: Duration of each diet (2 to 4 weeks)

  2. Modulation of GMRS over time during each intervention

    Microbiome data will be collected from all stool samples collected during the study to provide continual data on any changes. This data will be used to calculate the GMRS at each time point. A higher GMRS indicate high risk for Crohn's disease

    Measured: Duration of each diet (2 to 4 weeks)

  3. Measure of microbial taxa relative abundance over time during each intervention

    Microbiome data will be collected from all stool samples collected during the study to provide continual data on any changes in microbial composition

    Measured: Duration of each diet (2 to 4 weeks)

  4. Ability to maintain a balanced diet as measured by food intake records

    Through the submission of the daily food diaries an assessment on the ability to maintain the diet will be reviewed

    Measured: 6 weeks

  5. Adherence to the interventions

    Compliance to the diet will be monitored through an app throughout the study

    Measured: 6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Mediteranean to Western to Mediteranean Diet and Western to Mediteranean to Western Diet in people with Diet, Healthy and High Risk, run by Mount Sinai Hospital, Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Williams Turpin, PhD (416-586-4800 ext. 2086, wturpin@lunenfeld.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Personalized model (time frame: 7 weeks). It is what the study was designed to measure, not a finding.
