Filter by:This is a pilot study to compare the relative bioavailability between two peppermint oil formulations, namely a ileocolonic release peppermint oil and an small intestinal release peppermint oil (Tempocol®). This study is conducted as part of a future multicenter randomized controlled trial that will assess the therapeutic effect of the new peppermint oil formulation in IBS patients.
The purpose of this study is to investigate the effect of pectin, a kind of soluble dietary fiber, on clinical symptoms, gut microbiota and the immune status in patients with diarrhea-predominant irritable bowel syndrome
Some carbohydrates, complex sugars, which are found in grains, fruit and vegetables, cannot be digested by humans. When eaten they pass through the small bowel to the large bowel, or colon. Some bacteria that live in the colon are able to digest these carbohydrates, and use them as an energy source. This releases energy that humans can absorb, and may have other effects on health as well. The process also releases gases such as hydrogen and methane into the colon, which will eventually be released as flatulence. There is some evidence in animals, and humans, that changing the carbohydrate content of the diet may increase the numbers of bacteria in the colon that can use this energy source. Recent work has looked at how changes in colon bacteria and carbohydrate in the diet affect transit, the speed at which food and stool moves through the stomach and bowels. This undergraduate project will use techniques in Magnetic Resonance Imaging developed in Nottingham to investigate how a prolonged change in dietary carbohydrate might affect speed of transit through the bowel and gas production in the colon, and whether there is any immune reaction to the carbohydrate from the bowel wall.
the laxative-probiotic sequential treatment might reduce the symptoms of IBS and alter the fecal microbiota of the patients in a more robust manner .
The primary objective of this study is to determine whether giving SBI as a medical food starting with maintenance of health in the management of chronic loose and frequent stools in IBS-D subjects with SIBO after successful treatment with rifaximin can lead to more prolonged duration of benefit and delay symptom recurrence. SBI is the main ingredient in EnteraGam™, an orally administered prescription medical food for the dietary management of patients with enteropathy or chronic loose or frequent stools, including patients with IBS-D.
This longitudinal study is being done to understand mechanisms underlying development of irritable bowel syndrome (IBS) and the role of the gut bacteria in development of symptoms. This information will be used to determine whether temporal changes in gut microbial taxonomy and metabolism are associated with changes in symptom severity in IBS, and if targeted dietary interventions, including prebiotics, can reverse or moderate these changes.
Our overall objective with this study is firstly to provide a comprehensive assessment of intestinal permeability, mucosal barrier function using existing biomarkers and secondly to explore novel biomarkers for measuring intestinal permeability in patients with constipation predominant Irritable Bowel Syndrome (IBS-C).
Irritable bowel syndrome is characterized by abdominal discomfort and bowel habit change. It is increasing worldwide. But the pathophysiology of the irritable bowel syndrome is not proven. So, the treatment's target is the relief of the symptoms. Small intestinal bacterial overgrowth considered as the cause of the irritable bowel syndrome. Because, it is related to the postprandial abdominal discomfort and the abdominal discomfort could be relieved after taking antibiotics. There are several diagnostic methods for small intestinal bacterial overgrowth. hydrogen breath test is non-invasive method for diagnosis of the small intestinal bacterial overgrowth. But, there is no standardized cut-off value for the hydrogen breath test. So, we want to compare the hydrogen breath test between the irritable bowel syndrome patients and normal people. And then, we want to analyze the efficacy of hydrogen breath test for the diagnosis of irritable bowel syndrome.
Will Ranolazine improve bowel function and abdominal pain in human subjects with IBS-D?
The purpose of this study is to determine the amount of linaclotide and its active metabolite (MM-419447) excreted in breast milk after multiple, once daily doses of linaclotide (72 μg, 145 μg, or 290 μg) in lactating women receiving the drug therapeutically.
