Filter by:The primary aim of our study is to carry out a randomized trial to evaluate the efficacy of low-FODMAPs dietary therapy compared to conventional therapy for IBS patients recruited from tertiary hospitals in China. Secondary aims of this research include an analysis of clinical, physiological and microbiological factors that may predict IBS patient response to this dietary intervention.
The purpose of this study is to determine whether a 20- herb formulation, as a well characterised extract, is efficacious in treating irritable bowel syndrome (IBS) and also to identify efficacious and safe dosage of the formulation in treating IBS.
To compare with a randomized trial (n=15 per treatment group), effects of colesevelam and placebo treatment, on colonic transit, bowel functions, permeability and tight junction expression in rectosigmoid mucosa of IBS-D with Bile Acid Malabsorption.
This study will evaluate the impact of a Mediterranean-style diet on microbiome diversity compared to a typical American diet. The study will observe the microbiome composition comparisons in healthy volunteers as well as in patients with Irritable Bowel Syndrome with Diarrhea (IBS-D) to see if the consumption of a Mediterranean-style diet has a positive effect on improving symptoms of IBS-D.
Some people develop chronic abdominal pain with diarrhea or constipation after an episode of acute bacterial gastroenteritis. These symptoms can be consistent with post-infectious irritable bowel syndrome (IBS) and can last long after the acute infection is over. The exact reason why certain individuals develop these symptoms whereas others don't is not exactly clear. The researchers are studying changes in gastrointestinal permeability (movement of contents across the lining of the intestine) and transit (movement of food through the gastrointestinal tract). The researchers are also studying if there are any genetic risk factors that are associated with development of this disorder.
The aim of the study is to investigate how dietary fibre combinations affects gut physiology, particularly colonic gas production. Comparisons will be made between a single fermentable fibre (inulin), a non-fermentable fibre (psyllium) and a combination of the two. The study will also explore differences in response between diarrhoea-predominant and constipation-predominant IBS (IBS-D and IBS-C) respectively. The participants will have a preliminary meeting to ensure they are eligible, then will attend the MRI department on 4 occasions separated by at least 1 week. They will ingest a drink with the fibre product mixed in, and will have 8 MRI scans (each lasting approximately 15 minutes).
This open trial aims to evaluate feasibility and preliminary effectiveness of an internet-delivered CBT-program for children and adolescents with functional gastrointestinal disorders when implemented in regular care.
1. To assess the effect of multistrain probiotics on abdominal pain using a validated symptom severity score in IBS patients. 2. To assess the efficacy of a multi-strain probiotic supplement as a treatment option for IBS in a tertiary referral centre
The purpose of this study is to determine the amount and timing of when certain Fermentable Oligo-Di-Monosaccharides and Polyols (FODMAPs), specifically fructose, can be safely reintroduced into the diet of Irritable Bowel Syndrome (IBS) patients that have successfully completed a low-FODMAP elimination diet. The FODMAP diet is an effective treatment for IBS; however it is unclear how patients can successfully reintroduce and liberalize fructose into their diet. The low FODMAP diet is thought to reduce IBS symptoms by decreasing water content and gas production in the bowel and also possibly by altering gut bacteria. Although use of the FODMAP elimination diet can initially successfully treat IBS symptoms for up to 50-75% of patients, the reintroduction diet is difficult for patients to complete and maintain for long periods of time because current methods for reintroduction of FODMAPs are imprecise leading to frequent recurrent symptoms. As a result, patients often continue the low FODMAP elimination diet for additional months because they have difficulties knowing how to add back FODMAPs into their diet. There are no studies to date to help guide patients with FODMAP reintroduction.
This randomized, parallel, double-blind, placebo-controlled trial aims to determine the effects of daily administration of citrus extract over a period of 8 weeks on gastrointestinal health in patients with irritable bowel syndrome.
