Active clinical trials for "Irritable Bowel Syndrome"

The goal of this prospective observational cohort stuty is to assess the prevalence of overlap irritable bowel syndrome on coeliac disease in patients on gluten-free diet. The main questions it aims to answer are: percentage of the occurrence of irritable bowel syndrome in the population of Polish patients with celiac disease on restrictive gluten-free diet what is the correlation between the persistence of intestinal symptoms and adherence to a gluten-free diet (according to the patient's assessment) or confirmation of disease remission (based on histopathology or antibody level).

Bowel symptoms like constipation and abdominal pain are characteristic symptoms of irritable bowel syndrome (IBS). The pathogenesis and pathophysiology are not fully understood but subject to intense research, with emphasis on aberrations in the gut-brain axis, low-grade inflammation and gut barrier dysfunction that results in increased permeability and microbial translocation. Many patients with Parkinson's disease (PD) have reported bowel symptoms similar to that in IBS patients decades prior to the diagnosis of PD. Epidemiological studies show a significantly elevated risk of developing PD in IBS patients, though there is no knowledge on a pathogenic connection between these disorders. Recent studies show increased gut permeability and intestinal presence of pathological alpha-synuclein aggregates, the neuropathological hallmark in PD, indicating the involvement of the gut-brain axis. We aim to compare the presence of colonic alpha-synuclein between IBS, PD patients and healthy controls to relate these findings to intestinal permeability, ultrastructural mucosal changes, immune cell interactions, microbiota composition and brain function. This project could identify IBS groups at risk of developing PD and birth the development of early clinical diagnostic methods.

The present study aimed to compare the in vivo prebiotic properties of bread produced by traditional breadmaking techniques with that made using a modern breadmaking method on Irritable Bowel Syndrome-like symptoms in patients with quiescent Ulcerative Colitis. The expected outcome of the differential effects was a change in the faecal microbiome composition, which may indicate changes in the mucosa-associated microbiota.

Considering that PI-IBS is brought on by infection and gut microbiota may be associated with the onset of symptoms, the modification of altered gut microbiota with nonabsorbable antibiotics such as rifaximin-α or probiotics is often employed as first-stage treatment. Research in recent years has also shown the potential benefits of fecal microbiota transplantation (FMT) for IBS, which is the replacement of a sick recipient's gut microbiota with fecal material from a healthy donor. Even though the only officially approved indication for FMT at this time is recurrent Clostridium difficile infection, the effectiveness of FMT is nevertheless being studied for the treatment of other gastrointestinal and non-gastrointestinal pathologies including IBS. To date, several controlled and uncontrolled studies have been conducted to study the effectiveness of FMT for IBS, and most of them have demonstrated positive results. The investigators have not come across studies devoted to the study of the effectiveness of FMT in patients with PI-IBS in the available literature. So, the aim of the current study was to conduct single-centre, randomized clinical trial to assess the safety, clinical and microbiological efficacy of FMT in patients with PI-IBS.

The purpose of this pilot study is to examine the feasibility, acceptability, and preliminary efficacy of a customized positive psychology (PP) intervention for patients with irritable bowel syndrome (IBS) compared to a wait list control group.

The objectives of this study are to evaluate the safety, efficacy, and dose response of two delayed release formulations of linaclotide (DR; DR formulation 1 is DR1; DR formulation 2 is DR2) administered orally to patients with irritable bowel syndrome with constipation (IBS-C). Additional objectives include understanding how the two DR formulations compare with each other and with the FDA-approved 290 μg LINZESS® (the immediate release [IR] formulation of linaclotide).

The main objective of the study is to evaluate the effect on intestinal permeability of a supplementation with Lactibiane Tolérance® for 4 weeks (28 days) in patients suffering from irritable bowel syndrome (IBS) with diarrhea predominance. Secondary objectives of the study are to evaluate the effects of supplementation with Lactibiane Tolérance® for 4 weeks (28 days) in patients suffering from IBS with diarrhea predominance on intestinal permeability, inflammation of the digestive tract, symptoms and comfort. Single-center study in single open arms: 30 volunteer adults suffering from Irritable Bowel Syndrome (IBS) with diarrhea predominance and matching the criteria of inclusion and non-inclusion listed below.

This pilot study will be a randomized parallel trial comparing Mindfulness-Based Irritable Bowel Syndrome Eating Awareness Training done over an 8 week period to a standard low Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols diet.

This study will evaluate the efficacy and safety of eluxadoline 100 milligrams (mg) twice a day (BID) versus placebo for the treatment of patients with Irritable Bowel Syndrome with Diarrhea (IBS-D) who report that the use of loperamide in the prior 12 months failed to provide control of their IBS-D symptoms.
