Filter by:Current evidence suggests that the gut microbiota and dietary influences are as important as genetics in the aetiology of Crohn's disease (CD). We have recently shown that disease improvement, following treatment with Exclusive Enteral Nutrition (EEN), coincided with changes in the gut microbiota. The main purposes of this study are: a) to explore whether the gut microbiota changes we observed in this previous study in children with CD during EEN are disease specific or not, and b) to develop a novel food-based diet (Crohn's Disease TReatment-with-EATing/CD-TREAT diet) which will induce changes to the metabolic activity and bacterial composition of the gut microbiota of healthy people, similar to those seen on EEN, the first-line treatment for active paediatric CD. This study will produce high quality scientific evidence to move the CD-TREAT diet towards a preliminary clinical trial in patients with CD which is currently inappropriate and unethical to carry out in people with active CD undertaking contemporary medical treatment.
The purpose of this study is to evaluate endoscopic remission at Week 26 as assessed by ileocolonoscopy.
Vedolizumab is a new medication being used for the treatment of Crohn's disease and Ulcerative colitis. It works by blocking specific white blood cells (alpha 4-beta7 lymphocytes) from migrating to areas of inflammation in the gastrointestinal tract. Previous studies have shown that patients who have previous exposure to another type of medication for Crohn's disease and Ulcerative colitis (anti-TNF medications) do not respond to vedolizumab as well as those who have never been exposed. This study will investigate biologic markers in the blood and tissue the help identify possible reasons for this difference.
The daily requirement of threonine, an essential amino acid, will be evaluated in healthy adult males and in adult males with Crohn's Disease or ulcerative colitis using the indicator amino acid oxidation (IAAO) method. Participants will consume specially formulated diets with varying levels of threonine.
The primary objectives of the study are: -To evaluate the long-term safety and tolerability of MT-1303 in subjects with moderate to severe active Crohn's Disease（CD）
Food intake is mainly controlled through interactions between the gut and brain (the homeostatic control) and through our environment, with food exposure, mood and past experiences (the hedonic control) playing a major role. The link between the gut and the brain is mainly controlled through enteroendocrine cells (EC). These cells in the bowel sense nutrients in the food and link with the brain to control how much we eat. They make a number of hormones that link with the brain to control one's eating habits. Crohn's disease (CD) is an inflammatory disease of the bowel which can present with a number of symptoms including weight loss and loss of appetite. We thought some time ago that an increase in the number and function of these EC could play a central role. Since then we have carried out work which has shown that in CD these EC increase in number and produce more hormones after a meal. This finding could have a negative effect on food intake. This would be one explanation to the symptoms so commonly experienced by these patients. In CD we thus feel that there might be an imbalance in the appetite control. We expect an increasingly sensitive gut to food intake and a subdued mood and perception to food reward and that this imbalance will lead to a decrease in food reward and consequently a decrease in food intake. This study will be carried out using Healthy Volunteers and CD patients. We plan to measure food intake though telephone interviews and plan to analyse eating behaviour through 5 questionnaires.This study will help us to improve our understanding of what it is that controls food intake. This will be particularly important to patients with CD who routinely lose weight and appetite.
The primary objectives of the study are: - To evaluate the safety and tolerability of MT-1303 in subjects with moderate to severe active Crohn's Disease（CD） - To evaluate the clinical efficacy of MT-1303 in subjects with moderate to severe active CD.
To determine the efficacy and safety of multiple doses of ABT-494 in subjects with moderately to severely active Crohn's Disease with a history of inadequate response to or intolerance to Immunomodulators or anti-Tumor Necrosis Factor (TNF) therapy.
HealthPROMISE is a mobile application (app) for patients that allows regular tracking of symptoms by patients and communicates them to physicians. The purpose of this randomized controlled trial is to determine the impact of the HealthPROMISE application on improving patient outcomes. The trial will look at how much patients use the application, whether physicians change treatment in response to new information from patients, and how the patients quality of life change over the span of the study. The investigators hypothesize that HealthPROMISE will enhance physician-patient communication and improve clinical outcomes.
Can genetic markers be used to predict anti-TNF response? A cohort was established to identify SNPs associated with anti-TNF therapy in patients with inflammatory bowel disease.
