Brief Summary
The study involves characterizing the microbiota of patients with IBS, functional diarrhea, IBD, severe motility disorders and celiac disease. This will be complemented by a translational phase of human-mouse hybrid experiments in which germ-free mice will be colonized with feces from these patients with different GI disease and non-disease controls and we will compare symptoms, microbiota composition and histological changes in the gut and in the brain of the mice.

Outcome Measures
Primary Outcomes (1)
To identify different patterns of intestinal microbiota in patients diagnosed with chronic gastrointestinal disorders or controls
To identify different patterns of intestinal microbiota in patients diagnosed with inflammatory bowel disease, microscopic colitis, functional diarrhea, severe motility disorders, celiac disease and irritable bowel syndrome and to compare it with non-disease controls.
October 2013 - October 2026
Secondary Outcomes (3)
To study the effect of microbiota on the immune system
October 2013 - October 2026
To compare luminal microbiota composition vs. mucosa-associated microbiota composition in patients diagnosed with IBD, IBS, microscopic colitis, functional diarrhea, severe motility disorders and celiac disease and non-disease controls.
October 2013 - October 2026
To assess and compare the metabolic activity of gut bacteria of IBD, IBS, microscopic colitis, severe motility disorders, functional diarrhea and celiac disease patients and non-disease controls
October 2013 - October 2026
Study Arms (1)
Chronic gastrointestinal disorders
A cohort of 260 patients (150 diagnosed with IBD, 40 with IBS, 30 with celiac disease, 10 with MC, 10 with functional diarrhea and 30 non-disease controls) of either sex between 18 and 75 years of age consulting to either the GI Clinical Investigation, the Endoscopy Unit (McMaster University)
Interventions
Esophagogastroduodenoscopy and colonoscopy with video recording and biopsy collection
Eligibility Criteria
A cohort of 260 patients of either sex between 18 and 75 years of age consulting to either the GI Clinical Investigation, the Endoscopy Unit (McMaster University Endoscopy Centre)
You may qualify if:
- Diagnosis of IBD, active celiac disease (aTTG positive + endoscopic view and histological findings compatible), IBS (Rome IV criteria or physician diagnosis) severe motility disorders (severe constipation, severe functional dyspepsia) gluten sensitivity (IBS diarrhea predominant with positive anti gliadin antibodies and negative aTTG), functional diarrhea (Rome IV criteria), anal fissure and/or fistula or non-disease control individual or 1st degree family member of celiac patient.
- Willingness to participate
- Signed Informed Consent
You may not qualify if:
- Antibiotics in the last month
- Probiotics in the previous month
