Active clinical trials for "Irritable Bowel Syndrome"

Patients' fulfilling Rome III criteria for IBS with symptoms refractory to standard treatment who are referred to a specialist unit for hypnotherapy are consecutively included in the study. The patients are randomized to either individual or group treatment given by a nurse trained in hypnotherapy. The treatment consists of eight sessions of gut directed hypno therapy during twelve weeks. Effects are measured by validated questionnaires at baseline and at various time points during the treatment period as well as after the completion of the treatment.

The investigators know that many patients with irritable bowel syndrome (IBS) have functional variants of genes coding for sucrase-isomaltase enzymes. The investigators will now examine whether these functional variants are associated with defect degradation of sucrose and associated gastrointestinal symptoms

People with irritable bowel syndrome (IBS), especially those with diarrhea (IBS-D), often describe worsening symptoms after eating certain foods. A structured dietary approach may represent a reliable strategy to improve their symptoms. In this framework, the diet low in oligosaccharides, disaccharides, monosaccharides, and fermentable polyols (FODMAPs - LFD) has been demonstrated to mitigate symptoms and reduce inflammatory status, increase vitamin D content, and affect the lipidomic profile. Unfortunately, adherence to LFD can be somewhat problematic, needing continuous nutritional support. Other dietary approaches with putative beneficial effects have been proposed to overcome these limitations. Among them, Tritordeum-based foods (TBD, bread, bakery products, and pasta) in substitution of other cereals seem to achieve promising results. TBD may represent a valid alternative, with high palatability, especially among Italian patients for whom pasta is considered one of the main assets of dietetic culture and easier to manage in their daily habits. Given these premises, this study aims to evaluate, in a randomized single-blinded controlled trial, the effects of 12-weeks of TBD compared with LFD and dietary advice of the same duration in improving the symptom profile well as the intestinal permeability and reducing putative dysbiosis of IBS-D patients. Along with the clinical study, an evaluation of gluten and proteomic composition will be performed to examine more in detail the intrinsic characteristics of Tritordeum.

Abdominal pain remains the most deleterious symptom for patients with irritable bowel syndrome (IBS) and is causing a significant alteration of their quality of life. The visceral hypersensitivity seems to be one of the key mechanisms that could explain the abdominal pain in these patients. Current treatments, mainly symptomatic, are of limited effectiveness, especially in terms of relief of abdominal pain. The study will aim to evaluate the effectiveness of ethosuximide on abdominal pain in patients with IBS, its tolerance and its impact on patient quality of life, severity of symptoms related to IBS and the use of analgesics / antispasmodic / regulators transit.

Irritable bowel syndrome (IBS) is a common functional bowel disorder of the gastrointestinal tract affecting up to 20 percent of the adolescent and adult populations. It is characterised by abdominal pain, irregular bowel habits, altered stool consistencies and bloating, and is associated with impaired quality of life. IBS can be categorised into diarrhoea predominant type (IBS-D), constipation predominant type (IBS-C), and mixed type (IBS-M). Fecal microbiota transplantation (FMT) defined as infusion of feces from healthy donors to affected subjects has shown impressive results with high cure rates in patients with recurrent clostridium difficile infections. The investigators propose a randomised, placebo-controlled trial of FMT in patients with IBS.

Patients with diarrhea-predominant irritable bowel syndrome (IBS) and functional dyspepsia (FD) were examined and received treatment in the study. Severity of complaints and quality of life patients were assessed according to questionnaires. The state of the intestinal barrier (analysis of the protein composition, intestinal mucin levels in biopsies, serum zonulin level in blood), the composition of the gut microbiota (16S rRNA gene sequencing), bacterial metabolic function (short-chain fatty acid levels in feces), and the presence of gut inflammation (levels of lymphocytes and eosinophils in biopsies) were assessed in the patients. Patients were divided into 3 treatment groups: trimebutin + placebo, rebamipide + placebo, trimebutin + rebamipide. The above parameters were compared in patients before and after treatment.

Many patients with irritable bowel syndrome (IBS) do not experience adequate symptom relief with current treatments. The pathophysiology of IBS is diverse, controversial and not completely understood. The next disruptive frontier would be to find a cure where the effect is predictable and lasting. The study groups phase 2 pilot trial was the first indication of a possible benefit from treating IBS with fecal microbiota transplantation (FMT) (Number needed to treat only five) (Fecal microbiota transplantation versus placebo for moderate-to-severe irritable bowel syndrome: a double-blind, randomized, placebo-controlled, parallel-group, single-centre trial he Lancet Gastroenterology and Hepatology 2018). Additional results from the same trial show that the treatment response may be predicted (unpublished data), and that the pathophysiologic mechanisms behind the treatment response also can be identified (Effects of fecal microbiota transplantation in subjects with irritable bowel syndrome are mirrored by changes in gut microbiome, Gut Microbes 2020). This study is the first phase 3 trial of FMT for IBS worldwide. The hypothesis of the trial is that donor FMT is more effective than placebo FMT in treating IBS, with little adverse events or complications. Patients ≥18 years with IBS are enrolled at five Norwegian Hospitals in this double blind randomized, placebo controlled, parallell-group multi center trial. Participants are randomized to FMT from a healthy donor (intervention group), or their own feces (placebo group). The primary outcome is the proportion of patients with ≥75 points decrease in the Irritable bowel Symptom Severity score 90 days after treatment.

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.

The prevalence of migraine is higher in female patients with various intestinal diseases. An explanation could be that migraine is caused by a leaky gut, defined by increased intestinal permeability that permits particles to pass through the gastrointestinal wall. Probiotics, may be able to improve intestinal barrier function. OBJECTIVE: To test whether probiotics, as adjucnt therapy, can reduce incidence and severity of migraine attacks by reducing intestinal permeability.
