Filter by:The goal of this interventional clinical study is to study whether the consumption of QiMeiYan Probiotics in 25-35 young people with Mild irritable bowel syndrome (IBS Score 75 - 175) will reduce the frequency of Diarrhea. 140 eligible participants (70 males and 70 females) will be enrolled in two study sites and randomly assigned to two groups of products QiMeiYan Probiotics and placebo. All participants will consume assigned products once a day after meals and record the critical data such as photo of feces. Three site visits will be arranged and all clinical data will be captured and recorded into CTMS (Clinical Trial Management System) for statistical analysis. Researchers will compare the two groups to validate if the daily consumption of QiMeiYan Probiotics will reduce the frequency of Diarrhea in the study population.
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).
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.
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.
This is an open-label observational crossover trial to study the efficacy of a commercial dietary supplement and its effect on common symptoms of IBS (such as bloating, gas, heartburn, and other symptoms).
Irritable Bowel Syndrome (IBS) is a disease that affects a large number of people. Adequate treatment is difficult, partially due to the heterogeneity of the patients and the complicated pathology in which not all mechanisms are understood. Based on literature and in vitro screening within the public private IBSQUtrition consortium project, a turmeric supplement was selected for in vivo validation of its potential beneficial effects on fat-induced intestinal barrier disruption as measured with LPS translocation in IBS patients with a diarrhea-predominant subtype (IBS-D). The primary objective of this study is to determine the effect of turmeric supplementation on LPS translocation in IBS-D patients after a high-fat challenge. The secondary objective of this study is to determine the effect of turmeric supplementation on gastrointestinal complaints and LPS-related biomarkers in IBS-D patients after a high-fat challenge. In this double-blind, randomized, placebo-controlled cross-over trial 20 adult (18-70 yrs) IBS-D patients will be included. Study participants have to invest about 16 hours of their time in this study. They will visit the research facility three times. The risks for participation are very small if not negligible. Consumption of high amounts of saturated fat may cause some gastro-intestinal discomfort. Blood sampling will be performed via a cannula and the insertion can be a bit painful and may cause a bruise. The amount of blood that is drawn from participants is relatively small and within acceptable limits.
The study aims to test the effect of Ashtanga yoga on well-being in patients with irritable bowel syndrome (IBS). The intervention comprises group sessions on the Ashtanga school of yoga. Participants are recruited from primary care and measurements on well-being and IBS symptoms are conducted at pre-treatment, post-treatment and 6-month follow-up.
Viome costumers are consented and recruited for this study and complete the questionnaires upon enrollment. Any participant who previously self reported depression, anxiety, or Irritable Bowel Syndrome (IBS) qualify for this study. All participants receive Viome's diet, supplement and recommendations.
This is a Phase IV, open-label, single-center, proof-of-concept, pilot study to evaluate the effect of Lactibiane Tolerance® in treating leaky gut in IBS-D patients. 30 consecutive patients with IBS-D and an increased intestinal permeability assessed by 51Cr-EDTA or 99mTc-DTPA will receive the multistrain probiotic Lactibiane Tolerance® 10 billion CFU 1 capsule twice a day (30 minutes before breakfast and 30 minutes before dinner) for 30 days treatment. At the end of treatment, patients will repeat intestinal permeability assessment by 51Cr-EDTA or 99mTc-DTPA.
