Active clinical trials for "Crohn Disease"

Inflammatory Bowel Diseases (IBD) refers to a category of disorders, consisting of Crohn's Disease (CD) and Ulcerative Colitis (UC), where segments of the gastrointestinal tract become inflamed and ulcerated. Canada has among the highest incidence rates of IBD in the world - 16.3 and 12.3 per 100,000 for CD and UC respectively. In the absence of a cure, the current goal of treatment is to manage patients in a milder state of remission. However, maintaining (or even achieving) remission is dependent on timely access to specialist IBD care; which in light of rising incidence rates have proven to be challenging. Moreover, patients often experience flare-ups of their gastrointestinal symptoms, while awaiting access to specialist care. In recent years, there has been increased integration of telemedicine services in gastroenterology practice. This change has been driven by a desire among IBD patients to have more flexible follow-up care, where 'virtual' care is provided as an adjunct to in-person consultations. Within the context of IBD, telemedicine might be effective in delivering routine and timely follow-up care to high-risk patients. The purpose of this study to determine whether telemedicine-based follow-up care can effectively manage the gastrointestinal symptoms of high-risk IBD patients and reduce their need for preventive health care services.

A cohort of CD patients (total n=300) and a cohort of controls (healthy individuals and family members of CD patients, total n=200) will be recruited. We will analyze gut host pattern of tissue immune system and epithelial responses to putative exposome and microbial triggers, expression data in the gut using mRNA expression studies and genetic analysis of the resident bacterial flora are necessary to identify specific molecules and signal pathways as well as specific bacterial taxa involved in aberrant response and instigation of inflammation that is the driver of Crohn's disease. Therefore, We will obtain stool & blood samples and intestinal biopsy and/or resection specimens from CD patients, and blood, stool and intestinal biopsy samples from healthy individuals and a-symptomatic family relatives undergoing colonoscopy for reasons un-related to the study (e.g screening colonoscopy). Patients from both cohorts will also undergo environmental and dietary exposure survey. For environmental exposure, we will use the questionnaire developed by the International Organization of IBD (IOIBD), with some modification. Questions relate to five main different areas: (i) Childhood factors up to 20 years; (ii) food habits including daily, weekly or less frequent consumption; (iii) smoking habits; (iv) sanitary conditions such as the availability of in-house water tap, hot water tap or flush toilet; and (v) others factors including physical activity, oral contraceptive pill and stressful events before diagnosis. For mapping dietary habits we will employ an interview conducted by a trained dietician and using the validated structured FFQ (Food frequency Questionnaire).

Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases (IBD) currently affecting over 5 million patients globally, mostly young adults. These conditions are often debilitating, disabling and may markedly affect patient's quality of life. Despite important advances in research, the pathogenesis of IBD remains obscure, the incidence-rising, the condition - incurable, and drugs have a modest effect. The common denominator may be environmental factors, specifically diet and the microbiome, which remain a fundamental unmet need in IBD care as high quality randomized trials and mechanistic research are limited. Up to a quarter of patients with UC may undergo complete large bowel resection due to disease complications. In order to preserve bowel continuity, this surgery includes a restorative part with creation of a reservoir ("pouch") from normal small bowel instead of the resected rectum. The majority of these patients develop small intestinal inflammation in the previously normal small bowel creating the pouch ("pouchitis"). Based on our results from previous studies, we hypothesized that personalized antibiotics and dietary interventions will modify microbial composition and result in significantly improved outcomes, specifically resolution of inflammation and prolonged remission rates in patients with a pouch. Aims: Compare the effect of two antibiotic treatments on clinical, inflammatory and microbiological outcomes of patients with pouch inflammation. Evaluate the effect of combined microbiome-targeted antibiotic and dietary intervention as treatment and prevention strategy in patients after pouch surgery. Evaluate the effect of a microbiome-targeted dietary intervention as prevention strategy in patients after pouch surgery. Identify predictors for response to specific antibiotic and dietary interventions.

Compare the quality of life at 6 months between 2 populations of patients followed for terminal ileitis of Crohn's disease treated with anti-TNF or ileocecal resection.

Inflammatory bowel disease (IBD) encompasses two major forms of chronic intestinal disorders, Crohn's disease and ulcerative colitis (UC). Diagnosis is based on several macroscopic and histologic features including patterns of inflammation, crypt abscesses and granulomas. Confocal laser endomicroscopy (CLE) is rapidly emerging as a valuable tool for gastrointestinal endoscopic imaging, enabling the endoscopist to obtain an "optical biopsy" of the gastrointestinal mucosa during the endoscopic procedure. The main objective of this study is to determine endoscopic and endomicroscopic features of mucosal healing in patients with IBD.

Malnourished patients with IBD that receive pre-operative parenteral nutrition therapy will have fewer post-operative complications compared to malnourished patients that receive standard of care nutritional therapy.

The purpose of this study is to describe physician-reported clinical effectiveness outcomes, as determined by Harvey-Bradshaw Index (HBI) assessment, in biologic-naive participants with CD over 12 months following treatment initiation with vedolizumab.

Inflammatory Bowel Diseases are incurable, life-long conditions that significantly impact a patient's quality of life. Crohn's Disease and ulcerative colitis are the most prevalent inflammatory bowel diseases in the United States; both are characterized by chronic, relapsing inflammation of the intestinal tract, which manifests as symptoms of diarrhea, fecal urgency, fecal incontinence, fever, fatigue, abdominal pain and cramping. These severely debilitating periods of illness or "flare" alternate with times of remission when patients have few or no symptoms, and feel healthy. Despite periodic respite, many patients with IBD experience severe stress and anxiety even when they are well, because of the likely occurrence of episodes of disease in their future. This is exacerbated by the unpredictable frequency and inconsistent duration of flares that may last as long as several weeks or months. The goal for this study is to use non-invasive monitoring techniques to identify biomarkers that emerge, or change predictably, when a patient begins to relapse from remission to enter a period of disease - to find the earliest signs of an active flare. If the investigators identify a pattern of biomarkers that could alert a patient and their clinician to a flare as soon as it begins, it may be possible to intervene before symptoms present by changing medication and/or diet and lifestyle to lessen the severity of the disease flare. The biomarker fingerprint may also reveal new targets for therapeutics that could control IBD.

The purpose of this study is to look for the NOD2 gene in children with Inflammatory Bowel Disease (IBD) and their parents. We hope to understand this NOD2 gene better by determining whether children that have IBD have the NOD2 gene. In those with the NOD2 gene, we want to see if the type of gene abnormality predicts the nature of their disease and if the genetic information helps doctors decide what therapies and/or treatments to use for their patients. We also hope to explore the relationships between known serologic markers of IBD (ASCA, pANCA, ompC) and the clinical characteristics and course of children with IBD. About 1500 children and as many of their parents as possible will take part in this study. Children who are newly diagnosed with IBD as well as children that are being seen in the Children's Health System are eligible to participate in this study. We are looking for children 18 years old or younger to participate. If possible, we would also like both parents of the child to participate.

Subjects that participate in the practical workshop will improve their quality of life and will stay longer in remmision , in compare to the participants that will continue their regular threatment
