Filter by:Irritable Bowel Syndrome (IBS) is a widespread disease with variable symptoms that have an important impact on the quality of life. Despite the prevalence of IBS, its etiology and pathophysiology are still to be fully understood, but immune response is known to be involved. In this study, the investigators researched the variation of two specific cytokines, B-cell activating factor (BAFF) and platelet-activating factor (PAF), the levels of food-specific IgG and the symptom severity, using Irritable Bowel Syndrome - Symptom Severity Score (IBS-SSS), following a personalized an unrestricted-calorie diet.
The aim of this double blind placebo-controlled study is to evaluate the effect of BIOintestil on fecal microbiota, inflammatory chemokines and symptoms in patients affected by Irritable Bowel Syndrome (IBS).
This is an observational, open, longitudinal, multicentre study conducted in France. The study plans to enrol 119 patients with irritable bowel syndrome who will be included by about 50 general practitioners or gastroenterologists consulting in private offices. The treatment, Lactiplus® is a medical device, in the form of capsules containing L. gasseri LA806. The main objective of the study is to assess the effect of a 4-week treatment with the medical device on abdominal pain.
This randomized study evaluates the effectiveness of the a probiotic formula, compared with the antibiotic rifaximin, in the treatment of Small Intestinal Bacterial Overgrowth (SIBO) in Irritable Bowel Syndrome (IBS) patients.
The purpose of this research study is to see if a six-week yoga program delivered online/virtually via Zoom, reduces abdominal pain in people with irritable bowel syndrome (IBS). This study also looks at whether the yoga program changes the composition of microorganisms in the gut and their metabolites, and compares the program in people with IBS versus healthy people (also known as "healthy controls" or "HC"). People in this study are randomized (like flipping a coin) to one of two conditions: half of the people attend the online/virtual private yoga program delivered via Zoom for the first six-weeks, and half of the people wait for six-weeks and then attend the online/virtual private yoga program for six-weeks. The hypothesis of this study is that the practice of yoga induces shifts in the gut microbiota and microbial-derived metabolites, which will correlate with diminished abdominal pain.
The obtained results are likely to determine whether changes in the diet of patients with irritable bowel syndrome will affect their nutritional status. They will also allow you to assess whether dietary treatment will affect the resolution or alleviation, or severity of disease symptoms in IBS. The test results can be used in clinical practice. Participation in the study does not carry any risk of complications associated with undergoing a medical experiment.
This is a prospective, descriptive, observational research study designed to observe and document the clinical practice by domain experts, and how the knowledge of new findings that are published in the medical literature affect clinical decision making. The study will evaluate risk factors and co-variants, including genetic variants that are associated with disease progression such as pain, inflammation, organ dysfunction, disability and quality of life.
Study Aim: This study will explore the feasibility and effectiveness of a yoga program for patients with IBS. Methods: A superiority RCT with 30 participants per group. Adult patients with IBS fluent in English who do not have major physical impairments or cognitive, psychological, or psychiatric disorder will be recruited and randomly using the REDCap randomization module to either a yoga intervention delivered (a) a yoga intervention delivered online led by a yoga facilitator or (b) a advice only control group. The 8-week Hatha Yoga intervention consists of Yoga Namaskar, Nadi Shuddhi (alternate nostril breathing), mantra chanting, and breath watching. Group 1: Yoga program. Participants will be asked to practice the yoga program daily at home and will be given access to the yoga videos hosted on the University of Calgary study website, as well as written program instructions, and frequently answered questions. A brief description of the video content will be provided to inform the participant of its content and length. Additional website content will include study information, study schedule, and contact information, as well as a pre-recorded educational session. In addition to the daily program describe above, the facilitator-led intervention will be delivered online by a certified yoga facilitator using the Microsoft Teams platform. Participants in group of 3 to 5 will be collated to enhance effectiveness of the study processes. Our team has experience with this approach, as this strategy is currently used with previous yoga study. Yoga classes will be held once per week for 8 weeks, with the first session lasting approximately 1.5 hours and subsequent sessions up to 60 minutes. The total allocated time for the introductory session will include the class set-up, introductions, educational material (please see below), overview of practices, teaching of practices, practice corrections/enhancements, modifications, and practice expectations. Each follow-up class will include review from the previous week, questions and answers, individual corrections and/or modifications. For individual corrections, the yoga facilitator will ask the participant to do the practices and receive corrections, if needed. Group 2. Advice-only control group. This group will receive general education on IBS, the mind and gut connection, and the role of mind-body therapies in the management of IBS. Effectiveness outcomes will be assessed at baseline and 8 weeks. The primary effectiveness outcome will be the severity of IBS symptoms, and secondary effectiveness outcomes include microbiome analysis, quality of life, anxiety and depression symptoms, perceived stress, fatigue, and severity of somatic symptoms. Microbiome composition will be measured using shotgun metagenomic sequencing. Microbiome sequences will be analyzed for alpha diversity, beta diversity, species composition, functional composition and biomarker discovery. To determine the feasibility of each intervention, recruitment and attrition rates, adherence, program preferences and satisfaction, and adverse event outcomes will be evaluated.
Are you what you eat? How can dietary components influence microbial composition of the gut and function of the peripheral and central nervous system? The gut and brain is linked through complex mechanisms of sensorimotor functions of the immune system, the hypothalamic-pituitary-adrenal-axis, the enteric nervous system and microbiota. In this project, a multitude of factors contributing to the bidirectional neurobiological communication along the brain-but-axis will be investigated. No disease of the brain-gut axis has been elucidated, therefore our investigations involves approaching a large span of components and processes involved in the axis. This study is carried out as a case-report study (baseline, IBS n=100, healthy controls n=40) followed by a dietary intervention (IBS-D n=60). Through multivariate analyses, the investigators will identify patterns of factors contributing to patient symptomatology and pathology, followed by big data analysis leading to stratification of sub-classification of irritable bowel syndrome (IBS).
Low fermentable oligo-, di- and monosaccharides and polyols (FODMAPs) diet is taken as a possible strategy to improve symptoms in IBS patients. However, the gut-brain signalling mechanisms underlying this observation remain poorly understood. In this study, the investigators aim to study the brain mechanisms underlying the effect of intragastric administration of one specific FODMAP (fructans) on gastrointestinal and non- gastrointestinal symptom responses, changes in gut physiology(morphology of the gut, water content and intestinal motility), and to relate the findings to changes in gastrointestinal peptides. Intragastric administration of three different solutions will be given after an overnight fast: one FODMAP solution (fructans), a positive control (glucose) and a negative control (saline). The whole procedure consists of a functional magnetic resonance imaging (fMRI) and abdominal MRI examination, and will take approximately four hours. The participants will undergo the fMRI for one hour for assessing brain activity, during which blood samples will be collected. The abdominal MRI will be performed at 1-hour interval for three hours to assess pre and post stimulated changes in gut physiology, specifically the morphology of the gut water content and pan-intestinal motility. During the whole procedure, questionnaires for assessing the gastrointestinal symptoms and emotional state will be collected. The investigators hypothesise that fructans induce distension and increased sensations of pain, cramps and flatulence in the IBS group more than the HC. Furthermore, this will be associated with increased activation of pain-responsive brain regions in IBS compared to HC, which will be mediated by differential changes in gut peptide levels (↓ in orexigenic and ↑ in anorexigenic hormones).
