Active clinical trials for "Irritable Bowel Syndrome"

This study aims to assess the effect of active self- administered acupressure compared to sham self- administered acupressure on the health outcome for patient with diarrhea predominant Irritable Bowel Syndrome

Randomized controlled clinical study has been proposed to evaluate the safety and efficacy of ES1 probiotic strain and heat-treated ES1 postbiotic strain in individuals suffering from IBS-D.

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.

Background: Resilience refers to a class of variables highly relevant for wellbeing and coping with stress, trauma, and chronic adversity. Despite its significance for health, resilience is hardly examined empirically and suffers from poor conceptual integration. Irritable bowel syndrome (IBS) is a functional disorder with altered psychological stress reactivity and brain-gut-microbiota axis, which causes high chronic strain. Gut-focused hypnotherapy (GHT) is a standardized treatment for IBS targeting at resilience. An increase of resilience by GHT has been hypothesized but requires further investigation. Aims of the study were construct validation and development of an integrational measure of different resilience domains by dimensional reduction, and investigation of change in resilience in IBS patients by GHT. N=74 Gastroenterology outpatients with Irritable Bowel Syndrome (Rome III criteria) were examined in 7 resilience domains, quality of life, psychological distress and symptom severity. n=53 of these participate in 7 to 10 Gut-directed Hypnotherapy group sessions (Manchester protocol). Post-treatment examinations were performed 10 months after last GHT session.

IBS is the most common diagnosis in new patients in our pediatric gastroenterology clinic, accounting for 36 % of all new patients. Pediatric IBS patients always have a problem with defecation, characterized either as diarrhea predominant or constipation predominant. About one third of pediatric IBS subjects have d-IBS. There are no FDA approved treatments for children with d-IBS. There is evidence that diarrhea predominant irritable bowel syndrome d-IBS may be caused by a mild inflammation in the intestinal lining. Oral serum-derived bovine immunoglobulin protein isolate (SBI) is a medical food, believed to treat mild inflammation in the small intestine associated with some cases of d-IBS, especially those arising after acute gastroenteritis. It improved pain and diarrhea in adults with d-IBS. Our aim is to determine if SBI improves the number of spontaneous bowel movements in children with d-IBS.

This study is being conducted to see if serum-derived bovine immunoglobulin/protein isolate (SBI) is safe and well tolerated in pediatric patients with IBS-D. Main Hypothesis :Pediatric patients with IBS-D, who take SBI, will have no significant adverse events at 4 and 8 weeks and their quality of life will be better than the patients who receive placebo.

This is a pilot study to compare the relative bioavailability between two peppermint oil formulations, namely a ileocolonic release peppermint oil and an small intestinal release peppermint oil (Tempocol®). This study is conducted as part of a future multicenter randomized controlled trial that will assess the therapeutic effect of the new peppermint oil formulation in IBS patients.

The general aim of the current study is to describe the effect of pregabalin on colonic and sensory functions in adults with constipation predominant irritable bowel syndrome (IBS-C). Study hypotheses: Single-dose pregabalin 200mg increases sensation thresholds and decreases sensation ratings in response to balloon distension in the colon relative to pre-pregabalin treatment. Single-dose pregabalin 200 mg will increase colonic compliance and decrease colonic pain and gas thresholds in patients with irritable bowel syndrome constipation predominant. Single-dose pregabalin 200mg increases the colonic phasic and tonic response to a standardized meal.

Irritable bowel syndrome (IBS) affects about 15% of the U.S. population. There are still no effective and safe medications approved for the treatment of abdominal pain associated with bowel symptoms in IBS. This study will investigate the effects of an approved medication, Dronabinol, on the movement of food through the stomach and colon in subjects with a history of diarrhea-predominant Irritable Bowel Syndrome (D-IBS).

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).
