NCT07481422
The goal of this clinical trial is to learn if oral capsules containing lyophilized fecal microbiota transplantation (FMT) can safely and effectively treat refractory irritable bowel syndrome (IBS) in adults aged 18-65 years. The main questions it aims to answer are: Does treatment with lyophilized FMT capsules reduce IBS symptom severity compared with placebo? Does treatment with lyophilized FMT capsules improve quality of life, anxiety, and depression in patients with IBS? Are there differences in the frequency of adverse events between participants receiving FMT capsules and those receiving placebo? Researchers will compare lyophilized FMT capsules to placebo capsules to see if FMT reduces IBS symptoms and improves quality of life and mental health. Participants will: Be randomly assigned to receive either lyophilized FMT capsules or placebo capsules for three consecutive days. Take the capsules under supervision after receiving a proton pump inhibitor before the first dose. Complete questionnaires assessing symptom severity, quality of life, anxiety, and depression at baseline, 4 weeks, and 12 weeks after treatment. Attend follow-up visits at 4 weeks and 12 weeks after treatment and receive a telephone follow-up call 10 days after capsule ingestion. Report any adverse events and have vital signs and medical information monitored during follow-up. This study will help determine whether oral lyophilized FMT capsules are a safe and effective treatment option for adults with refractory IBS.
NCT06657001
The goal of this observational research study is to determine how diet contributes to various gastrointestinal related conditions. The main question investigators aim to answer is: Are host genetics, diet, and microbiome all important determinants of GI disorders, and how their relative contribution varies among individuals and populations.
NCT06708533
This intervention study explores whether a routine physical activity intervention can help manage or relieve symptoms of Irritable Bowel Syndrome (IBS) in adults who have been clinically diagnosed with IBS. The main questions it aims to answer is: • Primary Outcome: Does engaging in routine physical activity reduce the severity of IBS symptoms compared to baseline levels? Comparison Group: Researchers will compare the intervention group (receiving the 12-week physical activity program) with a control group (receiving no intervention for 12-weeks). Participant Activities and Interventions: * Complete a 12-week walking programme. * Visit the university on 3 occasions (baseline, week-6 and week-12) for biological sample collection and sub-maximal fitness assessments. * Complete a series of subjective health related questionnaires.
NCT02092402
The purpose of this study is to investigate the effect of fecal microbiota transplantation (FMT) on the symptoms of irritable bowel syndrome (IBS) patients.
NCT03550742
This is an open labeled, one-armed real-world study in IBS-patients. All participants will receive active treatment for 12 weeks. The primary objective of the study is to assess the effect of Human Milk Oligosaccharides (HMOs) on bowel function in adults with IBS. Secondary objectives are to evaluate HMOs' tolerability, effect on participant reported satisfaction with bowel habits, interference with life in general, quality of life, somatic symptoms, and anxiety and depression in all patients and subgroups of patients.
NCT01774695
Increased physical activity has in the investigators recent study been shown to improve symptoms in irritable bowel syndrome (IBS). The aim of this study was to assess the long term effects of the investigators previous intervention in IBS patients to improve physical activity. The investigators aimed to assess the long term effects on IBS symptoms as well as quality of life, fatigue, depression and anxiety.
