Filter by:Low fermentable oligo-, di- and monosaccharides and polyols (FODMAPs) diet is taken as a possible strategy to improve symptoms in IBS patients. However, the gut-brain signalling mechanisms underlying this observation remain poorly understood. In this study, the investigators aim to study the brain mechanisms underlying the effect of intragastric administration of one specific FODMAP (fructans) on gastrointestinal and non- gastrointestinal symptom responses, changes in gut physiology(morphology of the gut, water content and intestinal motility), and to relate the findings to changes in gastrointestinal peptides. Intragastric administration of three different solutions will be given after an overnight fast: one FODMAP solution (fructans), a positive control (glucose) and a negative control (saline). The whole procedure consists of a functional magnetic resonance imaging (fMRI) and abdominal MRI examination, and will take approximately four hours. The participants will undergo the fMRI for one hour for assessing brain activity, during which blood samples will be collected. The abdominal MRI will be performed at 1-hour interval for three hours to assess pre and post stimulated changes in gut physiology, specifically the morphology of the gut water content and pan-intestinal motility. During the whole procedure, questionnaires for assessing the gastrointestinal symptoms and emotional state will be collected. The investigators hypothesise that fructans induce distension and increased sensations of pain, cramps and flatulence in the IBS group more than the HC. Furthermore, this will be associated with increased activation of pain-responsive brain regions in IBS compared to HC, which will be mediated by differential changes in gut peptide levels (↓ in orexigenic and ↑ in anorexigenic hormones).
A randomized controlled trial to evaluate the short-term efficacy and long-term health economic impact of a dietary intervention compared to pharmacotherapy with a musculotropic spasmolytic agent for newly diagnosed or newly treated irritable bowel syndrome in primary care.
A high fermented, oligio-, di-, monosaccharide, and polyols (FODMAP) diet has been shown to exacerbate the symptoms of irritable bowel syndrome (IBS). Previous literature has shown significant improvement in IBS symptoms after adherence to a low FODMAP diet (LFD); hence, LFD is a viable treatment method for IBS and IBS-like symptoms. However, adherence to the LFD has proven to be difficult with participants stating that information provided by medical practitioners is generalized and nonspecific requiring them to search for supplementary information to fit their individual needs. Notably, studies that have used a combination of online and in-person methods for treatment have shown improved adherence to the LFD. The purpose of this study is to determine whether a novel machine learning dietary mobile application (ML-App) will improve adherence to the LFD compared to a standard online dietary intervention in populations with IBS or IBS-like symptoms over a 4 week period.
In this study we would like to understand how or if a food-based supplement affects gut symptoms such as bloating, stomach cramps and irregular bowel habits. Through using a digital symptom tracking app for a few weeks, you may just learn more about exactly what is triggering your symptoms!
Two hundrad patients are randomized to either 90 g transplant, 90 g transplant twice with 1week interval into the distal small intestine via working channel of a gastroscope, or to 90 g transplant into the coecum of the colon via working channel of a colonoscope. The patients shall complete 5 questionnaires measuring symptoms, fatigue and quality of life and collect a feces sample at the baseline, and at 3, 6 and 12 months after FMT. Dysbiosis and fecal bacterial are determined by using 16S rRNA gene.
Adults with irritable bowel syndrome (IBS) are being randomized to a yogic breathing or control condition. Participants randomized to the yogic breathing group will be asked to complete a 2-minute yogic breathing video 5 to 7 days per week at home for 4 weeks and control group participants will be asked to maintain their current activities. Participants in this group will be given access to the yogic breathing video at the end of the 4-week control period. IBS symptoms and autonomic and vascular function will be assessed at baseline and at the end of week 4 in both groups.
Irritable bowel syndrome (IBS) is one of the most common diseases of the digestive tract in adults, which pathogenesis is not fully understood. It is assumed that intestinal dysbiosis affecting the functioning of the gut-brain axis may be important. Probiotics are live microorganisms that, when administered at the right dose, have a positive effect on human health. Probiotic mechanism of action is related to the modulation of intestinal microbiota. Clinical studies confirm that probiotics administered to patients with IBS have positive health effects. Clinical effects depend primarily on the selection of probiotic strains, but no less important is their viability and stability in the preparation administered to patients. Unfortunately, obtaining stability (a strictly defined number of live probiotic strains in the preparation throughout the shelf life of the preparation) is very technologically difficult. As shown by the audit of the Polish Supreme Audit Office (NIK), almost 90% of probiotics sold on the Polish market do not meet these criteria. There were probiotic preparations that by the end of their expiration date had less than 100 live bacterial cells from the declared number of about one billion. The only preparations that successfully passed NIK inspections turned out to be preparations in which the technology of double microcapsulation of bacteria was used. New technologies are constantly being sought that increase both the survival of bacterial strains in the preparation and the resistance of the strains to hydrochloric acid and bile, which in turn contributes to delivering the right dose of probiotics to the target site of activity, i.e. the small and large intestine. Recent developed an innovative technology called bacterial cryoprotection, which, compared to traditional lyophilization, leads to an increase in the stability of the bacterial cell wall membranes and protects them against negative factors both external (high temperature, humidity etc.) and internal (gastric acid, bile). Therefore, the purpose of the clinical trial is to assess the effectiveness of cryoprotected probiotics in patients with IBS.
The purpose of this research is to assess if a new self-help app for IBS is an acceptable and effective intervention for improving the overall quality of life in patients with Irritable Bowel Syndrome.
This randomized study evaluates the usefulness of the I31 probiotic formula, alone or in combination with alverine/simethicone, against placebo, in the treatment of diarrhea-predominant or mixed irritable bowel syndrome
