Effect of Mediterranean Diet in Inflammatory Bowel Disease

April 1, 2024 updated by: Monica Guma, University of California, San Diego

Implementing Metabolomics Informed Diet on Inflammatory Bowel Disease Patients

The effects of diet on inflammatory bowel disease is an under-studied area of research. The investigators are interested in further investigating the role that diet contributes to inflammatory bowel disease severity. The investigators will collect blood and stool samples from patients with inflammatory bowel disease (IBD) before and after diet changes. The stool samples will be analyzed using metabolomics and microbiome analysis to determine changes after the new diet has been implemented. The investigators will then compare changes in the patient's overall disease state by measuring markers of inflammation including C-reactive protein (CRP) and fecal calprotectin to determine how this diet affects the disease state.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
short Crohn's Disease Activity Index (sCDAI)
Time Frame: 42 Days
Mild to moderate Crohn's Disease is defined by a short Crohn's Disease activity index (sCDAI) between 150-450, while those in remission from Crohn's Disease have an sCDAI score below 150. An sCDAI score exceeding 450 is used as a marker of severe Crohn's Disease.
