What this trial studies

This project aims to establish a multicentre, longitudinal cohort of individuals suffering from irritable bowel syndrome (IBS) to study the natural history and prognosis of the disease. The study will involve comprehensive phenotyping of patients through questionnaires, physiological explorations, and stool sample analyses to assess microbiota and metabolites. Over a period of 2.5 years, the study plans to include approximately 600 patients, allowing for the identification of subgroups with similar clinical or biological characteristics. This approach will facilitate a better understanding of IBS and its treatment outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of irritable bowel syndrome, potentially enhancing patient outcomes.

How similar studies have gone: Other studies have successfully utilized similar cohort approaches to understand IBS, indicating that this methodology is both tested and promising.
