Filter by:In the largest and most well-controlled randomized control trial of mindfulness-based interventions (MBIs) training in irritable bowel syndrome (IBS) to-date (N=325), the investigators will evaluate whether a smartphone MBI program (with attention monitoring and acceptance skills training; Monitor+Accept, MA-MBI) reduces daily life stress and IBS symptoms at post-treatment and two-month follow-up, relative to a matched MBI program with acceptance skills training removed (training in attention monitoring skills only; Monitor Only, MO-MBI) or to an active stress management training control group (Coping Control, CC). Participants will not only provide clinician and patient assessed measures of IBS symptoms at the three time points, but they will also provide sensitive experience sampling assessments (using Ecological Momentary Assessment) of their stress and symptoms in daily life at each time point. Finally, as an exploratory aim, participants will provide stool samples at baseline and post-intervention to provide the first ever test of whether MBIs can alter the gut microbiome in IBS. We will also conduct a sub-study that will include completion of a cold-water challenge performance task to test individuals' distress tolerance.
Irritable bowel syndrome (IBS) is one of the most common, yet still not fully understood, gastrointestinal disorders in adults. One suspected etiology involves intestinal dysbiosis, i.e. both quantitative and qualitative alterations in intestinal microbiota composition, which affects the gut-brain axis. Probiotics are live microorganisms, which-administered at the right dose-are beneficial for human health; their mechanism of action involves modifying the gut microbiota. Clinical study reports document that probiotic administration is beneficial for patients with IBS. The ultimate clinical effects depend primarily on probiotic strain selection. Our research team evaluated a multi-strain probiotic formulation and a multi-strain synbiotic (a combination of probiotic strains with short-chain prebiotic fructooligosaccharides) formulation as part of two randomized placebo-controlled clinical trials in patients with IBS with predominant diarrhea. The results indicated a beneficial effect of these formulations on the clinical course of IBS assessed with the international IBS symptom severity scale (IBS-SSS), with each of the study formulations exhibiting efficacy in different fields. The formulation composed of a mixture of Bifidobacterium and Lactobacillus strains reduced the levels of pain and improved the quality of life, whereas the synbiotic formulation effectively improved bloating and had a beneficial effect on the general condition of the intestines. A systematic review and meta-analysis published in 2020 showed that high doses of single-strain formulations, particularly those containing Bifidobacterium or Lactobacillus strains, may be more effective in IBS patients. Other reports demonstrated a high efficacy of the new-generation probiotic Bacillus coagulans in IBS. Therefore, the main objective of this research project is to assess the efficacy of single-strain probiotics containing Bifidobacterium lactis or Bacillus coagulans in patients with IBS.

Irritable bowel syndrome (IBS) is mainly associated with food intolerance and presents a particular challenge in gastrointestinal practice. The clinical symptoms are often associated by patients with the consumption of certain foods. This leads to strict elimination diets, and often without identification of the triggering food. In particular, the avoidance of wheat yields a relief of the clinical symptoms in many patients. Nevertheless, it is unclear which components of wheat are responsible for the symptoms. Besides the glutens, other wheat proteins, such as the amylase trypsin inhibitors, but also carbohydrates are discussed as triggers of the diseases. Confocal laser endomicroscopy (CLE) is a new diagnostic method for detecting the local effect of food on the mucosa. CLE enables microscopic assessment of the mucosa already during an endoscopic examination and also allows statements to be made about intestinal permeability through changes in the influx of fluorescein into the intestinal lumen. In the course of the study, diluted food solutions are applied to the mucosa after a detailed assessment of the mucosa via the endoscope. The changes in mucosa and permeability are observed and documented. Tissue samples are then taken for histopathological assessment of the degree of inflammation. Further biopsies are taken and cultured in vitro to produce human organoids. The organoids are stimulated with the food. Changes in proliferation, gene and cytokine expression are determined. The aim of the proposed project is to investigate the influence of the main allergens, e.g. wheat, soy, milk, yeast and chicken egg white on the intestinal mucosa. The data obtained will be compared with the histopathological findings and the in vitro data in the human organoid model. The long-term goal is to establish a valid patient-based rapid detection method for the detection of the triggering substances in patients with IBS or food intolerances.
This is a prospective, randomized, placebo-controlled, double-blind, multi-center parallel- design study to evaluate the effect of BL NCC3001 in subjects with Irritable Bowel Syndrome.
Irritable Bowel Syndrome (IBS) is one of the most common conditions diagnosed in gastroenterology practice. Acute infectious gastroenteritis represents the strongest known risk factor for IBS development; a condition known as post-infection IBS (PI-IBS). PI-IBS patients are more likely than sporadic IBS patients to exhibit a diarrhea-predominant phenotype. The investigators plan to prospectively recruit two groups of patients: patients with diarrhea-predominant post-infectious IBSand patients with diarrhea predominant classical IBS (non PI-IBS) who will be used as controls. Patients included in the study will receive for 28 days a capsule containing Tamarind seed polysaccharide containing xyloglucan, combined with a pea protein reticulated with grape seed extractand a prebiotic, the xilooligosaccharide (Gelsectan, Devintec Sagl) twice daily.

Patients with treatment resistant irritable bowel syndrome (IBS) are recruited from secondary care gastroenterology clinics in Stockholm and screened for eligibility criteria. Participants follow a 12 month treatment program at Nordic Clinic, a clinic offering personalized lifestyle interventions based on the functional medicine model. In parallel with the treatment program, the participant are clinically assessed for the evaluation of the treatment after 6 months, 12 months, 18 months and 24 months
Irritable Bowel Syndrome (IBS) is a disease that affects a large number of people. Adequate treatment is difficult, partially due to the heterogeneity of the patients and the complicated pathology in which not all mechanisms are understood. Based on literature and in vitro screening within the public private IBSQUtrition consortium project, a turmeric supplement was selected for in vivo validation of its potential beneficial effects on fat-induced intestinal barrier disruption as measured with LPS translocation in IBS patients with a diarrhea-predominant subtype (IBS-D). The primary objective of this study is to determine the effect of turmeric supplementation on LPS translocation in IBS-D patients after a high-fat challenge. The secondary objective of this study is to determine the effect of turmeric supplementation on gastrointestinal complaints and LPS-related biomarkers in IBS-D patients after a high-fat challenge. In this double-blind, randomized, placebo-controlled cross-over trial 20 adult (18-70 yrs) IBS-D patients will be included. Study participants have to invest about 16 hours of their time in this study. They will visit the research facility three times. The risks for participation are very small if not negligible. Consumption of high amounts of saturated fat may cause some gastro-intestinal discomfort. Blood sampling will be performed via a cannula and the insertion can be a bit painful and may cause a bruise. The amount of blood that is drawn from participants is relatively small and within acceptable limits.
This study is aimed to investigate the efficacy and safety of Colilen IBS, a Medical Device made of natural substances, even when taken in addition to other therapies, for the treatment of Irritable Bowel Syndrome.
