Active clinical trials for "Irritable Bowel Syndrome"

Food and their components are often reported as gastrointestinal (GI) symptom triggers in patients with IBS. The current interest in dietary management in IBS, has largely focused on the negative effect of poorly absorbed and subsequently fermented carbohydrates (FODMAP - Fermentable Oligo-, Di-, Mono-saccharides And Polyols). These unabsorbed carbohydrates can generate GI symptoms through osmosis, with increased amount of fluid in the gut lumen, and via modification of gut microbiota composition and function (fermentation and production of gas). Studies assessing diets low in FODMAPs have shown promising results in symptom improvement in some IBS patients, but not in all. The low FODMAP diet, as it is used today, is restrictive and difficult for patients to accommodate in their daily life. Moreover, the effect of this diet on microbiota composition and function is not defined, and there are also concerns that restrictive diets may lead to nutritional inadequacy. Fructan is a specific FODMAP which is built of fructose polymers. Examples of foods that contain fructans are wheat, onion, garlic and banana. The daily dietary intake of fructans varies approximately between 3 and 6 grams. Fructans are potential triggers of GI symptoms in IBS however, they are currently also used as prebiotic supplements. A recent systematic review and meta-analysis concluded that low dosages of fructans do not worsen GI symptoms, but they do increase the beneficial bifidobacteria. It remains unclear whether the potential benefits of fructans outweigh the potential harmful effects in patients with IBS. The investigators are aiming to assess the effects of fructans, as well as predictive factors and mechanisms involved, and to compare with placebo in IBS patients. The investigators will assess GI symptom severity, visceral sensitivity, intestinal gas production, gut immunity and microbiota, and metabolites produced in the gut.

Multicenter randomized controlled clinical trial comparing ebastine and mebeverine as treatment of irritable bowel syndrome Trial rationale To perform a randomized superiority trial comparing the clinical efficacy of ebastine and mebeverine To evaluate the impact of treatment with ebastine compared to mebeverine on quality of life and quality-adjusted life years Primary objective To provide further evidence of the superiority of histamine 1 receptor antagonism as novel treatment for patients with non-constipated IBS, as compared to mebeverine, one of the spasmolytics currently used as first line treatment of IBS. Secondary objective(s) To provide evidence that the histamine 1 receptor antagonist ebastine is more effective in reducing abdominal pain compared to the commonly used antispasmodic mebeverine

Irritable bowel syndrome (IBS) is a complex multifactorial functional disorder, whose pathophysiology is largely associated to an impairment of the intestinal microbiota composition, namely dysbiosis. Thus, the modulation of the gut microbiota has been proposed as a possible therapeutic strategy for IBS patients alongside with current available drugs. Fecal microbiota transplantation (FMT) is a promising strategy to restore intestinal eubiosis. In this randomised double-blind placebo-controlled trial patients diagnosed with IBS without constipation are assigned with 1:1 ratio to receive FMT from healthy donor or autologous FMT (placebo group) to assess the effectiveness of FMT on IBS symptoms and quality of life, to evaluate the safety of FMT among IBS patients and to estimate any change in the gut microbiota composition of IBS patients after the FMT.

Diet and lifestyle changes are the recommended first line treatments for symptom relief in irritable bowel syndrome (IBS). Currently the only diet that is widely recommended and for which there is good evidence of efficacy in IBS is one low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (low-FODMAP). While effective, the Low-FODMAP diet is burdensome and costly to patients and in clinical practice adherence to FODMAP restriction is less than optimal. Further, patients who respond to a FODMAP restriction often are reluctant to reintroduce more FODMAPs into their diet, which may deprive them of foods, particularly fruits and vegetables with important health benefits. Therefore, there is a need for other dietary interventions for IBS that are less burdensome to patients. This clinical trial assesses the efficacy of two dietary interventions.

purpose: to investigate the effect of pilates exercises on patients with irritable bowel syndrome. Methods fifty patients with IBS will be recruited and randomly assigned into two groups, group A and group B. Patients in both groups will receive a traditional dietary advice for IBS, but group A will receive additional pilates exercises. All patients will be evaluated pre and post treatment for Laboratory investigation for (TNFα and MDA),Bristol stool form , Irritable bowel syndrome symptoms ,quality of life, anxiety and depression and Fatigue.

The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with a variety of disorders, and that FMT could be a useful treatment. Randomized controlled trial has been conducted in a number of disorders and shown positive results, including alcoholic hepatitis, Crohn's disease (CD), ulcerative colitis (UC), pouchitis, irritable bowel syndrome (IBS), hepatic encephalopathy and metabolic syndrome. Case series/reports and pilot studies has shown positive results in other disorders including Celiac disease, functional dyspepsia, constipation, metabolic syndrome such as diabetes mellitus, multidrug-resistant, hepatic encephalopathy, multiple sclerosis, pseudo-obstruction, carbapenem-resistant Enterobacteriaceae (CRE) or Vancomycin-resistant Enterococci (VRE) infection, radiation-induced toxicity, multiple organ dysfunction, dysbiotic bowel syndrome, MRSA enteritis, Pseudomembranous enteritis, idiopathic thrombocytopenic purpura (ITP), and atopy. Despite FMT appears to be relatively safe and efficacious in treating a wide range of disease, its safety and efficacy in a usual clinical setting is unknown. More data is required to confirm safety and efficacy of FMT. Therefore, the investigators aim to conduct a pilot study to investigate the efficacy and safety of FMT in a variety of dysbiosis-associated disorder.

irritable bowel syndrome (IBS) is a well-known risk factor for diseases of the anal region (hemorrhoids, anal fissures, etc.) and large intestine (colon cancer, diverticular disease). Untreatable IBS disease not only impairs the patient's quality of life but also reduces the success of surgical treatment in these diseases. Today, only one-third of IBS patients achieve successful results with the treatment methods and diets used routinely. Balancing the composition of the gut microbiota may yield satisfactory results in this patient group. With the results of our study, we aim to reveal the effect of microbiome analysis and personalized diet on symptoms and its place in treatment in patients with IBS disease. Patients applying to Gastroenterology outpatient clinics in respective centers due to IBS will be randomized into two groups. The patients in the control group will follow the FODMAP diet protocol for IBS; In the study group, a personalized diet will be applied according to the gut microbiota. No nutritional supplements will be used in either group. Changes in defecation habits and quality of life scale of both groups will be evaluated at the end of 6 weeks and the results will be compared.

The clinical trial has a randomized, double-blind and placebo-controlled design, in which the effect of a probiotic mix wants to be evaluated, with a treatment of 12 weeks, in the evolution of the symptoms of Irritable Bowel Syndrome. The 12 weeks of the treatment are structured in four in-person visits: Visit 1 (initial; week 0), Visit 2 (halfway; week 4), Visit 3 (halfway; week 8) and Visit 4 (final; week 12).

The purpose of this project is to study the the efficacy and safety of probiotics implantation through infusion during colonoscopy in the treatment of functional constipation and irritable bowel syndrome. The study is a single-center, prospective, randomized, single-blind, controlled, cohort study. The invesitigators plan to enroll 80 patients with functional constipation and 80 patients with irritable bowel syndrome. The invesitigators will randomize the included study subjects. The experimental group receive basic treatment and a single infusion of probiotics through colonoscopy. The control group receive basic treatment and a single injection of normal saline through colonoscopy. The invesitigators will follow up the patients for 8-12 weeks. The primary endpoint is the efficacy of the single colonoscopic probiotics infusion in functional constipation and irritable bowel syndrome patients. The secondary endpoint is the safety of the single colonoscopic probiotics infusion in functional constipation and irritable bowel syndrome patients. Other exploratory objectives include the alterations in clinical indicators, fecal microbiota, and intestinal microbiota metabolites in feces and serum.

Irritable bowel syndrome (IBS) is a multifaceted disorder where diet plays a pivotal role in symptom generation and management. The traditional dietary advice given to patients in clinical settings are based on the NICE guidelines. Some of the advice included in these guidelines have limited scientific evidence. The aim of this study is to investigate the effectiveness of the traditional dietary advice in IBS, according to the NICE guidelines, within a primary health care setting, where treatment is delivered digitally and in groups of 8-12 individuals. As a sham comparator, one group will receive dietary advice according to the Swedish dietary guidelines regarding healthy eating habits.
