Filter by:Chronic diarrhoea is common and often believed to result from irritable bowel syndrome (IBS). However, up to 50% of patients with an IBS diagnosis may have something called Bile Acid Diarrhoea (BAD) instead. BAD is easily treatable however diagnosis currently relies on a complex test involving two full body scans. The aim of the study is therefore to investigate whether a simple laboratory test, that can be done on a single blood sample, would be appropriate instead. This laboratory test is called 7aC4. In order to determine whether 7aC4 could be a good test for BAD, it needs to be determined whether eating a meal can alter the levels of 7aC4. The aim of this study is to measure 7aC4 at several time points before and after eating a meal, to see what effect this has on 7aC4 levels.
This exploratory observational trial provides the opportunity to gather information on the effect of daily consumption of Poppi Apple Cider Vinegar Prebiotic Soda on gut health and digestion.
The primary research question to be addressed is: Does a 2'-FL-containing dietary supplement impact stool microbiota composition in adults with IBS? The primary measure for determining potential impacts of the 2'-FL-containing dietary supplement on stool microbiota composition is stool abundance of Faecalibacterium prausnitzii, a commensal intestinal bacteria. Additional measures related to determining potential impacts of the 2'-FL-containing dietary supplement on gut microbiota composition are stool levels of additional commensal intestinal bacteria and measures of intestinal microbial diversity.
To assess the effects of a Human Milk Oligosaccharide mix given once daily for 12 weeks on stool consistency and abdominal pain compared to placebo in individuals with Irritable Bowel Syndrome (IBS).
This is an open-label observational crossover trial to study the efficacy of a commercial dietary supplement and its effect on common symptoms of IBS (such as bloating, gas, heartburn, and other symptoms).
The aim of the present study is to compare the efficiency of low FODMAP and SSRD to reduce symptoms in IBS, and to study the mechanisms and consequences of the two diets.
A three month follow-up study to evaluate the effectiveness of a tailored anti-inflammatory eating plan guided by a registered dietitian to treat irritable bowel syndrome.
Cognitive Behavioral Therapy (CBT) is the most well researched and most effective treatment for IBS targeting the brain-gut-microbiome (BGM) axis, and preliminary data show that this therapeutic effect is associated with a reduction of brainstem connectivity with other brain networks. The increased prevalence of IBS in women, the higher rate of comorbid non-GI pain conditions, as well as the higher prevalence in female IBS of increased sensitivity to a variety of internal and external stimuli (multisensory sensitivity) suggest the presence of important sex differences in some of these BGM mechanisms. Research performed by UCLA SCOR during previous funding has established an increased responsiveness of the CRF-Locus Coeruleus (LCC) system in female IBS subjects, suggesting that this central noradrenergic brainstem system plays an important role in IBS pathophysiology. In addition, the study team's earlier research has begun to identify clinical, functional and structural brain mechanisms that may underlie these sex effects. Based on the preliminary data, the overall goal of this project is to use CBT as a probe to study the relationship between specific disease-related alterations of the brain, the gut microbiome, and symptomatic outcome, and identify the role of sex differences in these relationships. Investigators will study male and female IBS patients before and after CBT using the advanced neuroimaging and microbiome technologies of the overall SCOR.
The aim of this study is to investigate the effects of enzymatic treatment to reduce GOS (galactooligosaccharides) in legume-based crackers in IBS (irritable bowel syndrome) persons. The crackers are pea-based: the control crackers contain high amounts of GOS, while the enzymatically treated crackers contain a minimal amount of GOS. The participants will eat each type of cracker for three days (daily dose of 12 crackers) and report their gut symptoms (e.g. flatulence, stomach pain, bloating) by using a mobile app. There is a washout period of four days between the different crackers. In addition, the participants will keep food records on the cracker eating days as well as collect five fecal samples during the study. The participants will also report their physical activity and the number of defecations on each day. The study is carried out in a double-blinded crossover setting.
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.
