Vivatlac in Irritable Bowel Syndrome II (ViIBS2)
Multi-center,randomized, double-blind, placebo-controlled, 36 weeks trial investigating the effects of a nine-strain synbiotic (Vivatlac Synbiotikum) in IBS patients
Brachyspira and Intestinal Allergy-like Immune Reactions in Patients With Irritable Bowel Syndrome (IBS)
The aim of this study is to define local immune responses in the GI tract to food antigens in IBS patients, with and without Brachyspira infection, using advanced imaging. We hypothesize that Brachyspira infection can cause IBS symptoms by inducing loss of oral tolerance to dietary antigens through development of …
Fecal Amino Acids，Gut Taste Receptors and Irritable Bowel Syndromes
Clinical data, fresh feces and intestinal mucosal tissues of patients with diarrheal IBS were collected. High performance liquid chromatography, immunohistochemistry and immunofluorescence were used to study the amino acid levels in feces of patients with IBS, the expression of taste receptors in intestinal mucosa, and the correlation between symptoms of …
Electro-acupuncture for Irritable Bowel Syndrome With Constipation
The aim of the clinical trial is to evaluate the efficacy and safety of electro-acupuncture for irritable bowel syndrome with constipation (IBS-C) patients. 60 IBS-C patients will be randomized and allocated to either the electro-acupuncture arm or the sham acupuncture arm. We hypothesize that electro-acupuncture would result in superior symptom …
Irritable Bowel Syndrome and Control Volunteers: Diet Challenge
The study will investigate the relationship between fecal bile acids, short-chain fatty acids (SCFAs), and the gut microbiota in irritable bowel syndrome (IBS). The central hypothesis of this study is that specific shifts in the GI microbiome composition correlate with altered colonic SCFAs and BAs and contribute to IBS symptoms. …
Evaluate the Effect of Synbiotics in Irritable Bowel Syndrome
Irritable Bowel Syndrome (IBS) is a brain-gut-disorder characterized by a chronic relapsing-remitting nature of symptoms, including abdominal pain and altered bowel habits. Symptoms most likely result from complex interactions between several biological, psychological and social factors. Probiotic supplements are thought to improve IBS symptoms through manipulation of the gut microbiota. …
Effectiveness of a Dietary Supplement in Irritable Bowel Syndrome
Irritable bowel syndrome (IBS) affects around 5% of the general population and remains a daily problem in clinicians' practices, with inconsistent efficacy of treatments despite patients' high expectations. Intestinal hyperpermeability and visceral hypersensitivity are the two major components of IBS, and both can disrupt gastrointestinal function and ultimately impair patients' …
Gut Microbiome in Patients With Post-infectious Irritable Bowel Syndrome
Observational, multicenter, prospective study aimed at characterizing the gut microbiome in patients with post-infectious irritable bowel syndrome (PI-IBS) using whole genome sequencing (WGS). The study will compare microbiome composition and function between PI-IBS patients and two control groups (post-infectious subjects without irritable bowel syndrome -IBS- and healthy controls), with the …
Pathophysiological Effects of Persistently Colonized Microbiome on Irritable Bowel Syndrome
The goal of this clinical trial is to explore the pathophysiological effects of the persistently colonized microbiome in irritable bowel syndrome (IBS) patients. The main questions it aims to answer are: Question 1: the microbiome difference of the biofilm between IBS and healthy patients. Question 2: the metabolic product patterns …
A Single-arm, Open-label Clinical Trial to Evaluate the Effect of SMT04 in Irritable Bowel Syndrome (IBS)
Probiotic supplements improve IBS symptoms through manipulation of the gut microbiota. Metabolites derived from microbiota metabolism and host-microbiota co-metabolism have an impact on host intracellular signalling pathways. Although probiotic supplements improve IBS symptoms, the precise composition of probiotics that can achieve optimal response remains unclear. SMT04 (M3XTRA, GenieBiome Limited, Hong …
