Active clinical trials for "Irritable Bowel Syndrome"

The objective is to evaluate whether ONO-2952 modulates visceral pain perception produced by rectal distention in female patients with IBS-D

Will Ranolazine improve bowel function and abdominal pain in human subjects with IBS-D?

The aim of this study is to determine the efficacy of the administration of Bifidobacterium bifidum R0071, Bifidobacterium longum R0175, Lactobacillus helveticus R0052, Lactobacillus Delb. SSP bulgaricus R9001, Lactobacillus rhamnosus R0011, Lactococcus Lactis SSP. lactis R1058 et Streptococcus thermophilus (Probaclac™) given twice a day for 4 weeks on digestive symptoms evaluated subjectively in children aged 8 to 18 years with irritable bowel syndrome versus placebo. This study is a double-blind randomized controlled study. 84 children will included. After inclusion, a 15-day period of observation precedes the randomization at Day 0. Patients receive Probaclac or placebo for 4 weeks. At the end of the treatment period, patients are followed for a 2-week period of follow-up. 4 visits and 4 phone calls are planned during the study.

Selective serotonin reuptake inhibitors increase the level of serotonin. This study will use functional magnetic resonance imaging to examine how subjects with, and without, irritable bowel syndrome patients respond to serotonergic stimulation. Brain activation during emotional and arithmetic tasks and during visceral pain will be measured after serotonergic stimulation using the oral administration of Escitalopram (10 mg). The investigators will further integrate background parameters of the irritable bowel syndrome subjects and healthy controls (such as microbiota composition, genetic markers of serotonergic and inflammatory pathways, intestinal permeability, state of mood and visceral sensitivity) with the responses to the various challenges on the level of functional brain imaging. These responses may reveal a 'footprint' of the individual gut-brain axis function. Analyses of these individual footprints in multiple subjects with and without irritable bowel syndrome may reveal biosignatures characterising certain groups of patients according to specific gut-brain signalling response patterns. These biosignatures may be used to develop an individualised treatment algorithm for irritable bowel syndrome therapy.

Chronic abdominal pain is extremely common in individuals with Cystic Fibrosis (CF). Therapy for chronic abdominal pain is very limited and generally consists of osmotic laxatives or drugs that are used to treat irritable bowel syndrome (IBS), most of which are off-label and not proven to be effective for CF patients. Abdominal pain negatively impacts the quality of life (QOL). With the development of novel therapies for CF, life expectancy has significantly increased. There is, therefore, a critical need to identify treatment pathways for chronic abdominal pain in children with CF. In humans, abdominal pain is modulated by the vagus nerve. Stimulation of the vagus nerve has been suggested to reduce visceral sensitivity and abdominal pain. IB-stim is the Percutaneous Electrical Nerve Field Stimulation (PENS) device. It is a non-invasive, outpatient therapy. PENFS has been shown to be efficacious in pediatric patients with abdominal pain. The FDA has cleared and classified this device as class II, suggesting minimal to moderate risk. There is increasing evidence of intestinal inflammation in patients with CF, which could help explain the GI symptoms and differentiate from IBS. Studies have reported increased inflammation in the intestines using fecal calprotectin. With the implementation of this study, investigators hypothesize that the IB -Stim device will reduce their overall GI inflammation and abdominal pain.

SB-705498 has demonstrated efficacy in several preclinical and human experimental pain models. This study will investigate the efficacy of SB-705498 in patients with rectal pain. This will be a double-blind, placebo-controlled, two-way crossover study. 21 patients with faecal urgency (Group 1), and 21 patients with IBS (Group 2) will complete this study.

This study evaluates the effectiveness of a group cognitive behaviour therapy for Irritable Bowel Syndrome (IBS) in decreasing symptoms of IBS, improving quality of life, and normalizing the gut microbiome. Patients will complete an 11-week group cognitive behaviour therapy for IBS within 1 month of being deemed eligible for the study.

The purpose of this study is to assess the effects of AV608, a neurokinin 1 (NK-1) antagonist, in subjects with Irritable Bowel Syndrome.

Background: - Some research studies focus on digestive disorders, such as nutritional, gastrointestinal, and liver disorders. Researchers want to examine and treat people with digestive disorders in order to learn more about these disorders. They also want to study how digestive disorders run in some families. To do so, they will provide standard care to people with digestive disorders. They will also look at relatives of people with digestive disorders, such as parents, children, and siblings. Objectives: To examine and treat people with digestive disorders. To evaluate people with digestive disorders for research studies. Eligibility: Individuals of any age who have digestive disorders. Individuals at least 2 years of age who are first-degree relatives of the people with digestive disorders. Design: Participants will have at least one outpatient visit to the National Institutes of Health. The visit will last about 2 hours. All participants will be screened with a physical exam and medical history. They will also provide different samples for study. Samples may include blood, urine, and stool samples. Saliva and hair samples may also be taken. Skin biopsies and rectal swabs may be collected from adult participants. Participants with digestive disorders may be able to receive treatment through this study.

This is a 3-year prospective study too identify the role of exocrine pancreatic insufficiency in patients with abdominal pain who are undergoing upper endoscopy. An endoscopic pancreatic function test (ePFT) with secretin will be performed in children undergoing routine investigative EGD. The goal of this study is to identify the role of exocrine pancreatic insufficiency in patients with abdominal pain who are undergoing upper endoscopy, who otherwise would be labelled as recurrent abdominal pain (RAP).
