Active clinical trials for "Irritable Bowel Syndrome"

Title : A pilot single blind randomised controlled trial of the effect of a diet low in poorly digested carbohydrates on gastrointestinal form and symptoms in irritable bowel syndrome patients Acronym: CRAIGS Short title: Carbohydrate reduction and impact on gastrointestinal system Chief Investigator: Prof Robin Spiller Objectives: The purpose of this study is to: Investigate the proportion of patients with Irritable Bowel Syndrome who report moderate or substantial improvement in their symptoms after 2 weeks of following a diet low in Fermentable Oligo-Di-Monosaccharides and Polyols (FODMAPs) compared to patients who are on their habitual diet. Determine the difference in colonic volume of IBS patients receiving immediate low FODMAP dietary intervention after 2 weeks compared to patients who are not on the diet (delayed dietary intervention). Investigate the changes in self-reported food intolerance that occurs before dietary intervention. Trial Configuration: 2-arm, parallel group, randomised, controlled trial Setting : Research clinic within NIHR Biomedical Research Unit, Secondary care

Zeolite clinoptilolite is a volcanic mineral from the group of zeolites. The porous structure is associated with a large inner surface. Due to the anionic framework charge, ions (e.g., Pb^2+) can be absorbed or exchanged. The specific Panaceo PMA zeolite is approved as a class IIa medical device for the repair of the intestine inner lining. It is CE certified and complies with the relevant European Union regulations in terms of safety and effectiveness. Zeolite is known for its absorbing properties. Because of these properties and the results of several human studies, it warrants the investigation of possible effects on specific indications in human medicine, e.g. irritable bowel syndrome. The diagnosis "irritable bowel syndrome (IBS)" is according to the ROME Foundation, an US medical society. IBS is a disorder with dysfunction of the bowels, a latent inflammation is discussed. The present study aims to evaluate the following effects in patients with IBS: Primary endpoint: effect on the symptoms of IBS. Secondary endpoint: intestinal wall permeability, integrity of the tight junctions as measured by the change in zonulin concentration in the stool. Further endpoints: Inflammation parameters and anti-inflammatory laboratory parameters. Biodiversity of the gastrointestinal microbiome. histamine-associated parameters. Constipation as a possible side effect. For this purpose, a double-blind randomized controlled trial (RCT) is realized prospectively in a monocentric outpatient-controlled study. The subjects take the test compound daily (verum, reference substance) for 12 weeks and document the intake of the study-substance, intake of medications, stool-frequency and consistency. They receive "before" and "after" the intervention phase a blood and stool analysis for the determination of parameters for intestinal wall integrity (zonulin) inflammation (hsCRP, interleukin-10, calprotectin), histamine metabolism, microbiome diversity. The pilot study is realized ahead of the detailed planning of a later main study.

Irritable bowel syndrome (IBS) is one of the most frequent functional gastrointestinal disorder with a prevalence ranging from 10 to 15 percent. IBS results from an interaction among several factors, including genetic predisposition, gastrointestinal motility, visceral hypersensitivity, immune activation with minimal inflammation, alterations in intestinal microbiota, increased intestinal permeability, and food sensitivity. Of note, the management of patients with IBS is critical. Since quantitative and qualitative disturbances of intestinal microbiota can occur in IBS, interesting data support the use of probiotics to modulate intestinal microbiota. The present study aimed to investigate the effects of a novel formulation of B. longum BB536 and L. rhamnosus HN001 with vitamin B6 on the gut microbiota and intestinal permeability in IBS subjects.

A placebo controlled study to determine the efficacy and mode of action of ondansetron in the treatment of irritable bowel syndrome with diarrhoea.

This trial will evaluate the effect of ASP7147 on daily abdominal pain due to IBS-D during 4 weeks of treatment. It will also evaluate safety and tolerability in patients with IBS-D over the 4-week treatment period.

The purpose of this study is to compare the effects of 5g of Daikenchuto (TU-100) three times per day (Daikenchuto [TU-100] is a botanical agent that modulates gastrointestinal nerves), and placebo on rectal sensation (sensation ratings of urgency to defecate and sensation threshold for pain) in response to rectal balloon distension by barostat in patients with IBS.

The Canadian College of Naturopathic Medicine is conducting a research study on Irritable Bowel Syndrome (IBS), a common condition in North America. It is a long term, recurring gastrointestinal disorder that is estimated to affect 30% of the general population. IBS is characterized by abdominal pain and cramps, and bowel dysfunction such as diarrhea and bloating. The medicines that are currently used to help people with IBS are not as effective as we would like them to be. These medicines are usually only prescribed to reduce the pain of IBS and not actually treat the disorder itself. Recently, scientists have found that probiotics (beneficial bacteria that live inside humans) may help reduce the painful symptoms and diarrhea that are part of IBS. This research is being conducted to determine whether this particular combination of three probiotic bacteria (named Lactobacillus gasseri, Bifidobacterium bifidum and Bifidobacterium longum) will reduce the symptoms of severe IBS.

The aims of this study are to investigate the effect of famous herbal formula extract and probiotics on irritable bowel syndrome with diarrhea, and to determine whether these two experimental items affect intestinal permeability and the composition of intestinal microbiota.

This is a randomized, 12-week, double-blind, placebo-controlled, dose-ranging study in patients with IBS-C.

Irritable bowel syndrome (IBS) is a condition characterised by abdominal pain or discomfort in combination with altered bowel function (stool frequency and/or stool consistency), currently defined by the Rome III criteria. The current IBS definition specifies that there are no structural or biochemical abnormalities to account for the symptoms but there is growing evidence that in at least a subset of IBS patients, a discrete immune activation might be a key pathogenetic factor. The condition is prone to develop after a gastroenteritis, post-infectious IBS, and increased numbers of lymphocytes, mast cells and pro-inflammatory cytokines like Interleukin (IL)-1β, IL-6, Tumor necrosis factor (TNF)-α and a general increase in mucosal cellularity have been reported. Despite this, the efficacy of anti-inflammatory agents has been poorly investigated. This will be a randomised, double blind, placebo-controlled, parallel-group, multi-centre study that aims to include a total of 200 subjects with irritable bowel syndrome (IBS). All subjects will be randomised to receive either 3x800 mg of mesalazine (Asacol®) or corresponding placebo once daily for a total treatment duration of 8 weeks. Males and females aged 18 to 70 years who already are diagnosed with IBS based on the Rome III diagnostic criteria and with a symptom intensity of at least moderate level; defined as an IBS Severity Scoring System (IBS-SSS) score of ≥175 at both Screening (Visit 1, Day -21±2) and Baseline (Visit 2, Day 0) will be eligible to enter the study. Primary aim: To assess the effect of mesalazine (Asacol®) treatment compared to placebo on global IBS symptoms: A treatment responder will be defined by answering the satisfactory relief of IBS-symptoms question "yes" at the end of at least 4 out of of 8 treatment weeks. Secondary aims: To assess mesalazine (Asacol®) treatment compared to placebo regarding: Levels of inflammatory mediators in the rectal mucosa (e.g. neutrophil mediators, eosinophilic mediators, mast cell activity mediators and cytokines) measured by a new diagnostic tool, the Mucosal Patch Technology (MPT) by means of Enzyme-Linked Immunosorbent Assays (ELISA) Effects on number of immune cells (count per high power field) and cytokine content (immunohistochemistry) in mucosal biopsies Calprotectin levels in faeces (mg/kg) Individual IBS symptom parameters derived from a symptom diary and also measured by IBS-SSS
