Crohn's disease and ulcerative colitis are types of chronic intestinal disorder called inflammatory bowel diseases (IBD) that can affect the small and large bowel causing symptoms of abdominal pain, diarrhea, blood in the stool, and weight loss. Irritable bowel syndrome (IBS) is a milder form of IBD, with symptoms of abdominal pain, bloating, diarrhea or constipation, and blood in the stool. It is not known what causes diseases such as IBD and IBS. This study will look at the events in the gut that leads to leaky gut and inflammation in patients with IBD and IBS. The study will also see if medications such as rifaximin and mesalamine may reduce the amount of leaky gut.
Gluten-free diet has been shown to improve gut symptoms in patients with celiac disease and also in adult patients with diagnosis of Irritable Bowel Syndrome (Rome III criteria). Antibodies to native gliadin (AGA) have been suggested as a potential diagnostic marker of response to GFD. However, this has not been tested in a prospective study in IBS patients. Identification of predictors of a symptomatic response to GFD within the IBS population would improve the clinical management of these patients. The purpose of this study is to evaluate the effect of gluten-free diet on gastrointestinal symptoms and gut motility in patients with Irritable Bowel Syndrome stratified according to their antigliadin antibodies status. Additional purposes include investigating effects gluten free diet may have on other parameters: - Improvement of mood - Quality of life and general well-being - Changes in gut microbiota
The objective of this study is to evaluate the long-term safety and efficacy of linaclotide in post-marketing use.
In this randomized controlled study in patients with irritable bowel syndrome (IBS) the investigators plan to compare the effects of a structured patient group education (IBS School) with structured education provided via the internet. The effects of the interventions on GI and psychological symptom severity, knowledge and quality of life will be assessed with validated questionnaires at baseline, immediately after the intervention and 3 and 6 months after the intervention.
Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders, with a global prevalence of 11% according to a recent meta-analysis. The total cost of managing IBS in the United States is in excess of $30 billion per year, including indirect costs relating to loss of productivity of more than $20 billion. Abdominal pain/discomfort (i.e. visceral hypersensitivity) is present in all patients with IBS and remains the most therapy-resistant symptom. Apart from abdominal pain, which is measured subjectively using visual scales, several studies have shown a significant increase in rectal sensitivity, which is measured objectively using an inflatable balloon. Drugs which are shown to have objective effects on visceral hypersensitivity are crucial in the management of IBS. While certain drugs have shown to decrease abdominal pain, there is very little data to substantiate objective changes in visceral hypersensitivity. Rifaximin is a poorly absorbed antibiotic and the exact underlying mechanism of action for rifaximin in reducing the pain component of IBS remains unknown. However, rifaximin has been shown in randomized controlled trials to decrease abdominal discomfort in all subtypes of IBS. The investigators hypothesize that rifaximin is effective in decreasing rectal visceral hypersensitivity in IBS patients. In this study, the investigators propose to test this hypothesis by measuring visceral hypersensitivity using the graded balloon distention test, before and after a course of rifaximin. To test whether this effect is accompanied by treating SIBO, the investigators will also perform lactulose breath tests before and after rifaximin therapy.
This study is designed to evaluate the most applicable endpoints for evaluation of the Biomerica InFoods® IBS product.
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.
This is a pilot study to determine the efficacy of the Stress Management and Resilience Training (SMART) program in improving gastrointestinal and psychological symptoms, health-related quality of life, and satisfaction of care in patients with irritable bowel syndrome (IBS). Half of the participants will be enrolled in the SMART program initially. The other half will be placed in a self-management stress reduction program where they will read a popular stress reduction book over 12 weeks. Then they will have access to participate in the online SMART program.
To assess the effect of L. casei DG® (Lactobacillus paracasei CNCMI1572; Enterolactis® plus) on abdominal symptoms and gut microbiota metabolism/composition in non constipated patients with IBS (Irritable Bowel Syndrome). Patients will be randomized to receive L. casei DG® capsules, b.i.d. for 12 weeks the a 4 weeks Follow Up period will follow.
