NCT03729271
The purpose of this study is to learn more about how to improve treatment of patients with diarrhea predominant Irritable Bowel Syndrome (IBS-D) symptoms.Included patients will be requested to answer online surveys and will undergo treatment with rifaximin. Hydrogen breath testing and biologic samples collection will also be completed during the study.
NCT07103772
Irritable bowel syndrome is characterized by the presence of chronic, recurrent abdominal pain, alterations in bowel habits, and abdominal distension. The medical diagnosis is made using the Rome IV criteria. There are three IBS phenotypes: diarrhea-predominant, constipation-predominant, and mixed.
NCT06432569
Evaluation of the effects of butyrate ( BitirBioma) and palmitoylethanolamide( PEA=PeaBioma) on intestinal permeability and gut microbiota composition in patients with irritable bowel syndrome. Study B/P 3\_1 is an interventional study involving the use of food supplements on the market (BitirBioma Plus and PeaBioma Plus), single-center, double-blind, placebo-controlled, crossover, randomized, in n=50 patients with bowel syndrome irritable, diarrheal and mixed variant (IBS-D and IBS-M), lasting for one year. The study has two arms: Group 1: n=25 Treatment A e Group 2: n=25 Treatment B (with - Treatment A: 3 capsules/day of butyrate (625 mg) + 3 capsules/day PEA (200 mg) at a ratio of dosage of 3/1 - Treatment B: Placebo (3+3/day capsules of starch). Eligible subjects with IBS will be randomized in a 1:1 ratio to treatment A or treatment B for six weeks. After the first treatment period, there is a 14-day washout period. Hence, individuals will be treated with B/A treatment for additional six weeks, according to the crossover design. In the two treatment periods, subjects will be required to complete a visual analogue score VAS questionnaire to assess gastrointestinal symptoms and Stool Bristol Scales. During the visit, the subjects will have to record Questionnaire Rome IV to evaluate their quality of life. At the same time, it will be theirs required to provide: * fecal sample for the evaluation of the composition of fecal microbiota (Biomaplan Kit) * a urine sample for the evaluation of intestinal permeability (Gastropack) a capillary blood sample and a serum sample for the detection of Zonulin (Kit Healthy gut and Immundiagnostik AG ) * a capillary blood sample and a serum sample for the detection of Zonulin (Kit Healthy gut and Immundiagnostik AG )
NCT04855799
This trial is being completed to learn about how Aquamin® affects gastrointestinal permeability, or the control of material passing from inside the gastrointestinal tract through the gut wall into the rest of the body, in people with ulcerative colitis (UC), Irritable Bowel Syndrome with diarrhea (IBS-D), and in healthy individuals.
NCT06612411
This is a prospective, single-blind, randomized parallel study to investigate whether B. subtilis could improve clinical symptoms of IBS-D patients. Patients are randomly assigned by envelope method. A senior gastroenterologist is responsible for prescribing medication. Researchers are blind to patients' medication. Participants with IBS are recruited and randomized to receive a 4-week administration of B. subtilis-based probiotics. Clinical symptoms and stool samples are collected before and after the trial.
NCT03806959
Irritable bowel syndrome (IBS) is a chronic disease characterized by the association of abdominal pain and transit disorders. IBS affects 5 to 10% of the population. There are several forms of IBS: IBS-D (with predominant diarrhea), IBS-C (with constipation predominant) and IBS-M (mixed with alternating diarrhea and constipation). In the absence of a diagnostic test to confirm the existence of this syndrome, the diagnosis of IBS is based on clinical criteria (Rome IV criteria). In patients suspected of IBS, especially in patients with diarrhea (IBS-D or IBS-M), a colonoscopy with biopsies is often proposed in addition to biological tests (Complete Blood Count, C-reactive protein, thyroid stimulating hormon and anti-transglutaminase antibodies) by the physician or gastroenterologist to exclude an organic digestive disease such as celiac disease, IBD (Crohn's disease or ulcerative colitis), microscopic colitis or even neoplasia. The colonoscopy is an invasive exploration and does not allow exploration of the entire small bowel. The development of capsules allowed the exploration of the small bowel more recently of the colon. The new developed pan-capsule allows evaluation of both small bowel and colon. The aim of this work is to evaluate in patients younger than 50 years, presenting suspicious digestive symptoms of IBS with diarrhea, the interest of a strategy based on the pan-capsule as an alternative to colonoscopy to eliminate a diagnosis of organic digestive disease (celiac disease, IBD, neoplasia, ..).
NCT04899869
Irritable bowel syndrome (IBS) is the most common functional bowel disorder, being present in approximately 10% of adult Europoid population. The etiology of IBS is elusive. Literature indicates that modification of patients´colonic microbiota might ameliorate the condition. Here we test an intervention by faecal microbiota transplantation of artificially inflated microbiome diversity, versus autoclaved placebo.
NCT05130047
This single-center, randomized, double-blind, placebo-controlled study is designed to compare effects of aldafermin, (NGM282), 1 mg, and placebo given daily by subcutaneous injection on bowel functions and hepatic synthesis and fecal excretion of bile acids in patients with diarrhea associated with bile acid malabsorption (BAM).
NCT05339243
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.
NCT05277428
This study was conducted to investigate the effects of daily supplementation of L. plantarum APsulloc 331261(GTB1TM) on improvement of IBS symptoms.
NCT03557788
Irritable Bowel Syndrome (IBS) carries a high prevalence worldwide and imposes substantial economic burden on patients, healthcare systems and society. In recent years, dysbiosis of the gut microbiota and bile acid (BA) malabsorption have been identified as putative pathophysiological mechanisms. Bile acid metabolism and gut microbiota are closely related. When patients with IBS-D were compared to healthy subjects, total levels of faecal BAs do not differ, but increased faecal primary BAs and reduced secondary BAs have been repeatedly observed in patients with IBS-D, suggesting abnormal BA deconjugation. Rifaximin, a non-absorbable antibiotic, has been shown in a recent meta-analysis to produce a therapeutic clinical gain compared to other treatment options for IBS, including placebo, paralleled by a high safety profile. It is also now known that changes in fecal microbiota have been observed in patients with IBS who have responded positively to Rifaximin. The relationship between microbiota changes, metabolomics changes after Rifaximin is unclear. There is emerging data to suggest duodenal dysbiosis as a putative pathophysiology, which in one study, clustered together with salivary microbiota than with fecal microbiota. However, the oral microbiome in patients with IBS has never been explored, which could possibly explain the downstream observations of duodenal and fecal dysbiosis. The investigators aim to assess the changes in metabolomic and microbiota profile after Rifaximin treatment, between responders and non-responders. The investigators will also explore the oral microbiome in IBS patients, and assess its relationship with fecal microbiome between responders and non-responders.

This study will evaluate the possibility of a differential effect of eluxadoline on altered bowel function in Irritable Bowel Syndrome with Diarrhea (IBS-D) participants with and without evidence of Bile Acid Malabsorption (BAM).
