Pathophysiological Effects of Persistently Colonized Microbiome on Irritable Bowel Syndrome

Not applicable Interventional Second Affiliated Hospital, School of Medicine, Zhejiang University · NCT06013410

This study is testing how the gut bacteria of people with irritable bowel syndrome (IBS) is different from those without IBS to help find better treatments.

What this trial studies

This clinical trial investigates how the microbiome, specifically the biofilm, differs between patients with irritable bowel syndrome (IBS) and healthy individuals. It aims to identify variations in microbiome composition and metabolic products through colonoscopy and gut mucosal biopsy samples. By comparing these factors between IBS patients and healthy controls, the study seeks to uncover disease-specific patterns that could inform future treatments.

Who should consider this trial

Good fit: Ideal candidates for this study are adults diagnosed with type IV irritable bowel syndrome who have not undergone abdominal surgery.

Not a fit: Patients under 18, those with major diseases, or individuals with a history of severe gastrointestinal or cardiac diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new insights into the role of gut bacteria in IBS, potentially guiding more effective treatments.

How similar studies have performed: While the specific approach of this study may be novel, previous research has indicated that understanding the microbiome's role in IBS could yield significant insights.
