Active clinical trials for "Intestinal Diseases"

The incidence of Inflammatory Bowel Diseases (IBD) is in a continuous progression both in adults as in children. The colonoscopy is considered as the gold standard exam for the diagnosis and the follow-up of the patients presenting or suspected to have an IBD. The follow-up and financial management of this kind of pathology is very much dependent on the quality of the endoscopic images. Because colonoscopy is an expensive and invasive technique which assumes a general sedation, many efforts have been done to develop new less expensive and less invasive techniques in order to offer alternatives to the classic colon endoscopy. One of these new techniques is the colon videocapsule (CVC) endoscopy (PillCam® colon 2 - Given Imaging, Yoqneam, Israel). This is a new promising semi-invasive endoscopic technique which has been successfully validated with adults. We hypothesize that the CVC can be used in children with similar results in terms of efficacy, as is the case for adults. This prospective simple blind multicenter study, will investigate the diagnostic value of the CVC compared to the conventional colonoscopy under general sedation for the detection and the control of colon lesions in children presenting IBD. If the feasibility and the efficacy of the colon video capsule technique are also proven for use with children, then this new technique might become a very interesting alternative for the endoscopic examination of the colon because of being less expensive and less invasive. Moreover, this technique would be very useful as a means of lesions detection all along the digestive tract and not limited to the colon only.

The purpose of this study is to evaluate the efficacy and safety of vedolizumab intravenous (IV) in non-end-stage primary sclerosing cholangitis (PSC) participants with underlying inflammatory bowel disease (IBD).

Oral polio and rotavirus vaccines are significantly less effective in children living in the developing world. Tropical enteropathy, which is associated with intestinal inflammation, decreased absorption and increased permeability, may contribute substantially to oral vaccine failure in developing country settings. Other possible causes of oral vaccine underperformance include malnutrition, interference with maternal or breastmilk antibodies, changes in gut microbiota, and genetic susceptibility. Primary Objective: to determine whether tropical enteropathy impairs the efficacy of oral polio and rotavirus vaccines in children in Bangladesh. Secondary Objectives: 1) to determine the impact of an inactivated polio vaccine (IPV) boost on the efficacy of oral polio vaccine and 2) to determine the efficacy of oral rotavirus vaccine to prevent rotavirus diarrhea The polio and rotavirus randomized clinical trials are embedded as secondary objectives within the exploratory study of tropical enteropathy. The primary and secondary outcome measures are relevant to the randomized clinical trials.

The study aims to investigate how to give the diagnosis of Irritable Bowel Syndrome. The investigators compare two parallel groups of primary care patients, in the age of 18-50 years with gastrointestinal complaints where the GP suspects IBS. All included patients fulfil international diagnostic criteria (ROME III) and have no danger signals. Group 1: The diagnosis is based on the diagnostic criteria and few blod tests Group 2: The diagnosis is a diagnosis of exclusion after investigations with extended blod tests, examination for milk- and gluten intolerance, stoll for ova and parasites and scopy of the intestine. After receiving the diagnosis of Irritable bowel syndrome all patients are informed about the condition. The investigators follow the patients for 1 year. The investigators hypothesis is that the two investigation programmes (group 1 and 2)are equal with respect to the patients´ quality of life, symptoms and satisfaction and also with respect to finding of organic diseases.

The purpose of this study is to assess the safety and efficacy of intravenous iron sucrose in comparison to oral ferrous sulfate in improving iron deficiency anemia in children with inflammatory bowel disease.

Most of the studies evaluating the roles of MRE and WCE conducted in pediatric patients have been retrospective with the main goal of making a diagnosis in patients with suspected IBD. The current study is the first prospective study in children with known IBD assessing the roles of MRE and WCE in identifying disease exacerbation. This study will help to identify if capsule endoscopy is superior or complementary to MRE in the evaluation of suspected disease exacerbation in IBD patients.

Irritable Bowel Syndrome (IBS) is a common condition characterised by abdominal pain or discomfort and altered bowel habit affecting up to 10% of the population. There are several groups of patients that are based on differing bowel patterns including IBS with diarrhea (IBS-D) and those with post infective IBS (PI-IBS) whose symptoms begin after an acute infection. Saccharomyces cerevisiae, the yeast used in bread making has been shown to reduce the duration of infectious diarrhoea. Part of the benefit maybe that it can destroy bacterial toxins. Recent studies suggest an increase in proteases (chemicals which breakdown proteins) in the stool of patients with IBS-D. The investigators think that this yeast may benefit patients with IBS-D and PI-IBS by reducing the amount of protease in stool. This is important because proteases have been shown to be potentially important in generating some of the discomfort experienced by patients. The investigators will study patients with chronic IBS-D who will receive 2 weeks treatment with the yeast or placebo followed by a 4 week gap and then a further 2 week treatment with placebo or the yeast, with the treatments allocated randomly. The investigators will also study 30 subjects who still have persistent loose bowel function 6 weeks after an infection with Campylobacter jejuni, one of the commonest causes of gastroenteritis in the UK. Subjects will be randomised to take either the yeast or placebo for 4 weeks . In both studies, the investigators will examine the effect of treatment on stool proteases, stool frequency and consistency and abdominal discomfort; the investigators will also take blood samples to examine some aspects of immune system function. The results of the study may suggest how yeast provides a benefit in patients with IBS and diarrhea and will provide data for a larger clinical trial.

The purpose of this study is to assess the effect of a standardized postoperative bowel regimen of over-the-counter medications in subjects undergoing minimally invasive urogynecologic surgery.

The purpose of this study is to determine the safety and feasibility of using allogeneic bone marrow derived mesenchymal stem cells (MSCs) to treat people with medically refractory Pouchitis.

This study plans to learn more about the effects that creatine monohydrate has on disease activity in ulcerative colitis. Creatine is a substance that is naturally produced by the body and is found in foods, such as meat and fish. Creatine helps to provide energy to some body tissues, such as the colon. In the colon, this energy allows cells to form a tight barrier between molecules in digested food and bacteria and the body's infection-fighting cells within the colon underneath this barrier. If the barrier becomes "leaky" molecules may pass through and lead to inflammation. This "leakiness" may contribute to the colon inflammation seen in ulcerative colitis.
