A Multistrain Probiotic in Patients With Irritable Bowel Syndrome With Predominant Constipation — EPORE  

Irritable Bowel Syndrome With Constipation Clinical Trial

Official title:
Effect of a Mixture of Probiotics (Lactibiane Reference) in Patients With Irritable Bowel Syndrome Predominantly Constipation and Assessment of a Potential Biomarker (Resolvin D1): an Exploratory Study

Clinical Trial Summary

Probiotics efficacy is mainly assessed by subjective endpoints such as the FDA responder rate or global relief, which partly explain contradictory results obtained in clinical trials with probiotic bacteria. Objective biomarkers of IBS will allow to measure the efficacy of probiotics. In the case of IBS-C, serum resolvin-D1 appears to be an interesting candidate due to its non-invasive and discriminating character compared to a healthy population. It is, inversely correlated with the severity of symptoms. Resolvin-D1 modulates the duration and intensity of inflammation by regulating the transcription of cytokines, chemokines and their receptors as well as other proteins involved in inflammation. Resolvin D1 could serve as a predictor of probiotic response based on its baseline value.

Clinical Trial Description

Resolvin D1 levels will be measured in patients with IBS-C as defined by the Rome IV criteria before 6 and 12 weeks after supplementation with a mixture of probiotics. The progression of IBS-C symptoms will also be assessed throughout the study. The correlation with resolvin D1 levels and the severity of IBS symptoms will be investigated. The efficacy of the probiotic mixture in relieving the symptoms of IBS-C will be measured and compared based on the levels of resolvin D1. ;
