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, ..).
The aims of this study is to investigate a blood-based biomarker that can replace endoscopy in patients with inflammatory bowel disease. For this purpose, blood sample of patients wiht inflammatory bowel disease (ulcerative colitis, Crohn 's disease) was collected at the same time the endoscopy is performed, stored after centrifugation, and analyzed accordingly. Selected biomarkers from the blood sample were investigated to compare those of patients with inflammatory bowel disease and those of general controls. Males and females over the age of 19 participated in the study and are excluded if they have chronic kidney disease or blood clotting disease. The outcome is a find of a blood-based biomarker that best reflects a disease activity.
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.
Consecutive patients with Irritable Bowel Syndrome with Constipation (IBS-C) will be recruited from the outpatient clinics of the University of Michigan Health System. Eligible patients will be asked to participate in a study that will test the efficacy the PEG 3350 + a diet low in fermentable oligo, di, monosaccharides, and polyols (FODMAP) vs. PEG 3350 plus sham diet. Blinding dietary advice trials is challenging and therefore the sham diet was based on the criteria set forth by Staudacher et al. which emphasizes that the diet must give the impression that is the true intervention diet with similar restrictions, modifications, and time intensity without impacting the intake of essential nutrients, fiber, and FODMAPs. An example of the sham diet's carbohydrates includes: apples, bananas, and pears, and wheat. Oranges, raspberries, strawberries and rice would not be allowed. Additionally, the physicians analyzing the data will be blinded as to which group the patients were randomized.
This crossover randomized controlled trial will evaluate the effects of gluten and gluten combined with amylase-trypsin inhibitors (ATIs) on inducing intestinal and extra-intestinal symptoms in irritable bowel syndrome (IBS) patients. All participants will be put on a gluten-free diet and then challenged with muesli bars containing either purified gluten, gluten with ATIs, or nocebo.
Irritable bowel syndrome (IBS) is one of the most commonly diagnosed functional bowel disorders (FBD). IBS is diagnosed by symptom-based criteria，while the available literature suggests that symptom-based diagnostic algorithms, which often used for clinical and research studies, have poor sensitivity. Although diagnostic algorithms can discriminate IBS from health or upper gastrointestinal tract conditions, studies do not provide convincing evidence that the criteria can discriminate IBS from organic disease of the colon. Rectal bleeding, anemia, weight loss, fever, family history of colon cancer, and age above 50 years are considered the warning signs of severe gastrointestinal disease. Colonoscopy is the most direct way to rule out organic colonic diseases. There is no consensus so far on whether patients with suspected IBS lacking warning signs need colonoscopy or not. In 2016, the Rome IV criteria was updated and published. However, there are few studies on the clinical practice based on Rome IV. The value of alarm symptoms in discriminating organic disease from functional disorders remains uncertain and further research is needed. To evaluate the predictive value of alarm symptoms of IBS patients based on Roman IV, the investigators designed this cross-sectional study.
Fecal microbiota transplantation (FMT) is a strategy that infuses a fecal suspension containing a healthy donor's microbiota into a patient's gut to restore his/her intestinal microbiome. FMT has a higher cure rate than standard antibiotic treatment for recurrent Clostridium difficile infections,and shows promising results in Inflammatory bowel disease（IBD）.However, few studies have evaluated whether FMT is effective to treat Irritable bowel syndrome(IBS).The investigators propose to determine the efficiency and safety of FMT in patients with Irritable bowel syndrome.
This study of the efficacy and safety of Plecanatide in children 6 to <18 Years of Age with Irritable Bowel Syndrome with Constipation (IBS-C)
This is a multicenter, randomized, double-blind, placebo controlled clinical trial, in order to evaluate the efficacy and safety of Chinese Medicine JCM-16021 for diarrhea-predominant irritable bowel syndrome. All patients will be evaluated for study eligibility at Visits 1 (baseline) and 2 (2 weeks). On visit 2, patients who meet the criteria will be randomly assigned to receive 8-week treatment of either JCM-16021 Granules or JCM-16021 placebo Granules. The investigators, research assistants and participants are not aware of the treatment assignments throughout the study. Treatment codes will only be broken after the completion of study. The assessments at Visit 3 (4-week post treatment) and at visit 4 (end of 8-week treatment) are used to measure treatment response (i.e. changes from baseline). Assessment at visit 5 (end of 8-week follow up) is to determine any sustained response to treatment. All the visits will be carried out in HKBU and CUHK clinics.
