What this research studies
You would be compared with two groups of other patients to see what differs between people who have microscopic colitis and those who do not. Researchers will collect your medication and hormone use history, information about body weight, and stool samples to study gut bacteria using 16S rRNA sequencing. The team will compare microbiome diversity and specific bacterial groups between cases and controls and revisit earlier unexpected findings about medications and obesity. The goal is to expand earlier case-control work into a larger, more detailed analysis.
Who could benefit from this research
Good fit: Adults diagnosed with microscopic colitis, especially those with chronic watery diarrhea who can provide medication/hormone history and stool samples, are the ideal candidates.
Not a fit: People without microscopic colitis or those unable to provide required clinical information or stool samples are unlikely to benefit directly from participating.
Why it matters
Potential benefit: If successful, the work could point to modifiable risk factors or microbiome features that lead to better prevention or new treatments for microscopic colitis.
How similar studies have performed: Earlier smaller case-control work, including the team's prior phase, found lower gut microbiome diversity in cases and unexpected lack of medication links, but larger confirmatory studies remain limited.
