Active clinical trials for "Irritable Bowel Syndrome"

Gastrointestinal (GI) infection with Campylobacter causes inflammation in the bowel and can change bacteria in the gut. Certain individuals with Campylobacter infection are also known to develop chronic bowel problems such as Irritable Bowel Syndrome (IBS). The researchers are doing this study to understand if changes in gut bacteria and gut mucosal lining during an acute infection can help identify individuals who might be at risk for developing problems in the future.

The purpose of this study is to study the relationship between the bile acids, short chain fatty acids and bacteria within the intestines. The hypothesis is that changes in the bacterial composition of the stool are associated with the differences in bile acids and short chain fatty acids in patients having irritable bowel syndrome compared to healthy individuals.

The IMAGINE Cohort Study will identify and recruit a cohort of 8000 patients with IBS, IBD and healthy controls (2000 of each) who will be assessed in terms of their psychological status, dietary intake, gut microbiome, metabolomic and inflammatory markers and genotype, health-related quality of life, and health care resource use and associated costs. The cohort and healthy controls will be followed prospectively for up to 5 years after the completion of study enrolment.

During an online assessment participants will fill in questionnaires evaluating demographic data, psychological variables, the degree of self-assessed physical activity and symptoms of irritable bowel. Dietary intake will be assessed by a newly developed food frequency questionnaire (FFQ) and a 4 days food diary. In order to validate the FFQ in different populations, participants will be recruited from university students, staff of UZ Brussel and VUB, and from the community by advertisement (including social media). IBS patients will be recruited from the gastro-enterology outpatient clinic.

This cohort study implements patient reported outcome measures (PROMs) for patients with bodily stress syndrome in a clinic for functional disorders.

This research is a clinical trial aimed at improving the gut microbiome of patients with Irritable Bowel Syndrome (IBS) through a temple stay experience. Participants in the study are expected to participate in a temple stay experience for a maximum of 8 days. During the temple stay experience, participants are required to fill out a daily symptom questionnaire related to irritable bowel syndrome and record their diet and bowel movements using a dedicated mobile application. Upon completion of the temple stay, participants will conduct an evaluation of personal satisfaction with the experience. Through this, the study aims to collect and analyze data related to the Templestay experience with the goal of improving the gut microbiome of patients with IBS.

Functional digestive pathologies are defined by symptoms such as functional dyspepsia, gastroesophageal reflux, irritable bowel syndrome, gastroesophageal reflux, functional constipation, functional diarrhea, functional bloating, the opioid-induced constipation and fecal incontinence, without organic substratum. These diseases are very common in the general population (20%) and represent the first cause of consultation in city gastroenterology. The objective of this study is to collect prospective clinical and tests data and a biological collection from biological samples collected as part of the standard care. This collection could identify diagnostic or prognostic markers of the therapeutic response.

To set up a cohort of at least 400 IBS patients in order to identify different patient subgroups according to phenotypical and genotypical patterns and To set up a biobank for future translational studies on the pathophysiology of IBS, in order to identify genetic factors to unravel the pathogenesis of IBS and to provide novel therapeutic targets.

The SIMBA Capsule is a small, single-use, ingestible capsule that allows for the non-invasive sampling of small bowel contents using purely mechanical means. The study will compare the microbial and metabolomics analysis from the sample collected with the capsule series, to same-participant symptom questionnaires and stool microbial analysis.

Irritable bowel syndrome (IBS) is common medical disorder and represent a group of diseases of the gastrointestinal tract that is characterized by chronic abdominal pain , bloating , passage of mucus or straining with bowel movements, sense of incomplete evacuation after bowel movements or sense of urgency to move the bowels.Several parasites including Entamoeba. histolytica, Giardia spp., Blastocystis. hominis, and Trichinella spp. have been discussed as contributing factors to the development of IBS. B. hominis is one of the most common human intestinal protozoa in both developing and developed countries. some studies have reported a significant association between the parasitic infections, especially Blastocystis, and IBS.Cryptosporidium has been reported in IBS patients, with the onset of gastrointestinal symptoms after an acute episode of cryptosporidiosis despite recovery and parasite clearance.Numerous studies have been conducted to evaluate the association between the parasitic infections and IBS. Aim of the work: To detect prevalence of intestinal parasitic infections in irritable bowel syndrome patients in sohag.
