Filter by:Colonoscopy is the current standard method for evaluation of colonic disorders such as colorectal cancer, IBD, polyps, and other conditions.
Irritable bowel syndrome (IBS) is a highly prevalent functional pathology which currently has no real standardized and effective therapy, despite having a significant impact on quality of life and on social-health costs. Post-biotics have demonstrated in various in vitro and in vivo studies the ability to modulate the microbiota, the intestinal barrier function, the immune response as well as having systemic effects, with prospects for good efficacy in treatment of IBS.
Intervention: (Weeks 1-2, Visit 3-4) - Starting from the second week after the date of consent, patients with IBS will be randomized 1:1 into two groups. The first group (20 patients) will receive one week of a low FODMAP supplemented with fermented milk followed by one week of a low FODMAP content supplemented with fermented beans. The second group (20 patients) will receive a low FODMAP diet supplemented for one week with fermented beans followed by a second week of a diet with a low FODMAP diet supplemented with fermented milk. The microbiome of the patients will be evaluated after the first and second weeks along with data related to weight. After the second week, the metabolome and physical characteristics. The enrollment period will last for one year. The analysis of clinical data will be completed within one year after patient enrollment. Analysis of laboratory data will be performed in parallel.
Adult IBS patients with symptoms refractory to standard medical treatment will receive online nurse-administered, gut-directed hypnotherapy in groups. The primary outcome measure was change in gastro-intestinal symptom severity.
In this study, the investigators conduct a remote, eight-week, two-arm, randomized controlled trial that assesses the benefits, primarily measured through the irritable bowel syndrome (IBS)-targeted HRQOL (health-related quality of life), of an immersive, disease-targeted virtual reality program compared to a non-immersive virtual reality program for patients with IBS.
We will sample intestinal microbiota using a microbiome sampling capsule in Healthy, Irritable Bowel Syndrome (IBS), and Functional Gastrointestinal Disease.
This clinical study aims to evaluate the use of i3.1 probiotic in participants who meet the Institute of Medicine (Canadian Consensus Criteria) case definition for ME/CFS and who may or may not be diagnosed with irritable bowel syndrome (IBS). The main questions it aims to answer are: - how effective is the usage of the i3.1 probiotic to reduce gastrointestinal (GI) inflammation and normalize the GI and systemic/brain interface? - how well is it working on IBS severity? The study sample is 100 male and female participants aged 45 to 70 years with ME/CFS (per the Canadian Consensus Criteria); one-half of the participants will have co-morbid IBS (per Rome IV criteria). Participants will receive an i3.1 or a placebo and be assessed at baseline, at eight weeks, and at 12 weeks (four weeks post-treatment completion).
The aim of this work is to identify whether the digital treatment program Mage-tarmskolen has an effect on patients with IBS. Our secondary objectives is to address multiple aspects of digital treatmtent success of the different modules. The patients will be randomized to one of four arms and will be delivered different kinds of digital treatment. All patients will have access to ask questions to a registered dietitian. Primary end point is the proportion of patients with treatment success in the low FODMAP, behavioral therapy or both groups, versus the patient education group (sham). Treatment effect is defined as an improvement of 50 points or more on the IBS severity scoring system at 3 months after treatment start compared to the score before treatment.
GI disorders are influenced by the gut microbiome. To date, sampling of the small intestine in GI disorders has been limited. The investigators plan to sample the small intestinal contents during endoscopy for research purposes.
The aim of this study is to better understand how tenapanor affects the metagenomics and metabolomics of patients with irritable bowel syndrome with constipation (IBS-C). Tenapanor is the newest FDA-approved agent for IBS-C. It is a small molecule that inhibits the NHE3 receptor, leading to impaired sodium and water absorption in the intestine. Previous clinical trials comparing tenapanor to placebo showed that a 50 mg dose of tenapanor led to increased bowel movements and decreased abdominal pain. This study consists of an 8-week treatment period in which subjects will ingest one capsule of tenapanor (50 mg per dose), twice daily, and send in stool samples following 4 weeks and 8 weeks of treatment.
