Examining gut microbiome changes in IBD patients with C. difficile infections

Research on Biomarkers of Clostridioides Difficile Infection in Inflammatory Bowel Disease Patients Defined by Gut Microbiome and Fecal Metabolomics Alterations

Observational RenJi Hospital · NCT05714566

This study is trying to see how the gut bacteria of people with inflammatory bowel disease changes when they have a C. difficile infection compared to those who don't, to help understand the infection better.

What this trial studies

This research aims to investigate the differences in gut microbiota and fecal metabolomics between patients with inflammatory bowel disease (IBD) who are infected with Clostridioides difficile and those who are not. By analyzing bacterial genera and fecal metabolites, the study seeks to identify markers that could help distinguish between these two groups and understand their implications in the pathogenesis of C. difficile infections. The study will include inpatients diagnosed with ulcerative colitis or Crohn's disease and will compare their microbiome profiles to healthy individuals without IBD or diarrhea.

Who should consider this trial

Good fit: Ideal candidates for this study are inpatients aged 18 to 75 diagnosed with ulcerative colitis or Crohn's disease.

Not a fit: Patients with diarrhea caused by other infections or those with other metabolic or inflammatory diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and therapeutic strategies for IBD patients at risk of C. difficile infections.

How similar studies have performed: While there is ongoing research into the gut microbiome and its implications in various diseases, this specific focus on IBD and C. difficile is relatively novel.
