Filter by:Multicenter randomized controlled clinical trial comparing ebastine and mebeverine as treatment of irritable bowel syndrome Trial rationale 1. To perform a randomized superiority trial comparing the clinical efficacy of ebastine and mebeverine 2. To evaluate the impact of treatment with ebastine compared to mebeverine on quality of life and quality-adjusted life years Primary objective To provide further evidence of the superiority of histamine 1 receptor antagonism as novel treatment for patients with non-constipated IBS, as compared to mebeverine, one of the spasmolytics currently used as first line treatment of IBS. Secondary objective(s) To provide evidence that the histamine 1 receptor antagonist ebastine is more effective in reducing abdominal pain compared to the commonly used antispasmodic mebeverine
Irritable bowel syndrome is a functional bowel disorder that affects many Canadians. The syndrome involves abdominal pain and change in frequency or form of bowel movements, and these symptoms can lead to a decreased quality of life for patients. Primary care physicians are dissatisfied with current referral processes, and patients may wait a long time to receive the correct diagnosis. Diet is known to exacerbate symptoms of IBS. In Canada, accessing dietary treatment for IBS is a challenge due to lack of resources. Some patients lack access to dietary interventions, and others are given advice that is not evidenced based. Use of eHealth technology, such as virtual education delivered by a dietician, may allow for more widespread access to dietary interventions for IBS. Virtual education can include one on one dietary education, online group-based education, and the use of apps. Currently, there is a gap in knowledge whether dietary intervention for IBS, delivered virtually by a dietician, is effective in treating IBS.
Irritable bowel syndrome (IBS) is the most common GI condition with global prevalence ranging between 10-20%. Although the exact cause is not known there are increasing insights concerning the possible multifactorial etiology including low grade inflammation, neuromodulation, dysbiosis, impaired integrity of the intestinal barrier and more. Currently, it is believed that changes in the microbiota may activate mucosal innate immune responses, resulting in increased epithelial permeability, activated nociceptive sensory pathways, and dysregulation of the enteric nervous system. Nearly two thirds of patients with IBS perceive their GI symptoms to be food related, hence, food intolerance may be important factor in the pathogenesis. Diet is a part of IBS treatment but adherence, on the one hand, and restriction, on the other, remain a major problem. [Chey WD, Am J Gastroenterol,2016]. Confocal laser endomicroscopy (CLE) is a technique that permits real-time detection and quantification of changes in intestinal tissues and cells, including increases in intraepithelial lymphocytes and fluid extravasation through epithelial leaks. Based on CLE analysis of IBS patients with a suspected food intolerance, exposure to candidate food antigens caused immediate breaks, increased intervillous spaces, and increased IELs in the intestinal mucosa. These changes are associated with patient responses to exclusion diets. [Fritscher-Ravens A et al, Gastroenterology. 2019, Gastroenterology. 2014] This technic, also efficient according to former studies, is costly and invasive. The Alcat Test is a lab based immune stimulation test in which a patient's WBC's (white blood cell) are challenged with various substances including foods, additives, colorings, chemicals, medicinal herbs, functional foods, molds and pharmaceutical compounds. The Alcat Test objectively classifies a patient's response to each test substance as reactive, borderline or non-reactive. Based on these classifications, a customized elimination/rotation diet may be designed.
The clinical trial has a randomized, double-blind and placebo-controlled design, in which the effect of a probiotic mix wants to be evaluated, with a treatment of 12 weeks, in the evolution of the symptoms of Irritable Bowel Syndrome. The 12 weeks of the treatment are structured in four in-person visits: Visit 1 (initial; week 0), Visit 2 (halfway; week 4), Visit 3 (halfway; week 8) and Visit 4 (final; week 12).
The purpose of the study is to monitor safety and to evaluate the efficacy of a probiotic formulation on abdominal pain, abnormal defecation, comorbid mood disorders (anxiety and depression) as well as general quality of life in adults with IBS-D.
To evaluate the relation between the clinical presentations and the psychiatric co-morbidities with the quality of life in patients with irritable bowel syndrome.
Impaired intestinal permeability and microbial dysbiosis are important pathophysiological mechanisms underlying irritable bowel syndrome (IBS). ReFerm®, also called Profermin®, is a postbiotic product of oat gruel fermented with Lactobacillus plantarum 299v. In this experimental study, we investigated whether ReFerm® has a beneficial effect on the intestinal epithelial barrier function in patients with IBS.
Chronic diarrhoea is common and often believed to result from irritable bowel syndrome (IBS). However, up to 50% of patients with an IBS diagnosis may have something called Bile Acid Diarrhoea (BAD) instead. BAD is easily treatable however diagnosis currently relies on a complex test involving two full body scans. The aim of the study is therefore to investigate whether a simple laboratory test, that can be done on a single blood sample, would be appropriate instead. This laboratory test is called 7aC4. In order to determine whether 7aC4 could be a good test for BAD, it needs to be determined whether eating a meal can alter the levels of 7aC4. The aim of this study is to measure 7aC4 at several time points before and after eating a meal, to see what effect this has on 7aC4 levels.
This exploratory observational trial provides the opportunity to gather information on the effect of daily consumption of Poppi Apple Cider Vinegar Prebiotic Soda on gut health and digestion.
The primary research question to be addressed is: Does a 2'-FL-containing dietary supplement impact stool microbiota composition in adults with IBS? The primary measure for determining potential impacts of the 2'-FL-containing dietary supplement on stool microbiota composition is stool abundance of Faecalibacterium prausnitzii, a commensal intestinal bacteria. Additional measures related to determining potential impacts of the 2'-FL-containing dietary supplement on gut microbiota composition are stool levels of additional commensal intestinal bacteria and measures of intestinal microbial diversity.
