Filter by:Prognostic factors in Inflammatory Bowel Diseases (IBD) are currently mainly based on clinical factors (disease extension, perianal involvement, need for surgery, use of immunomodulators…). All of immunological markers (or serological) of IBD have a diagnostic role in indeterminate colitis (ulcerative colitis vs crohn's disease) but they never have been considered as predictors of IBD course in adults. Among the most used, anti-neutrophil cytoplasm antibodies (ANCA) and Anti-Saccaromyces cerevisiae antibodies (ASCA) allow the distinction between ulcerative colitis (ANCA+/ASCA-) and Crohn's disease (ANCA-/ASCA+), and their combined use has a sensitivity and a specificity of about 85%. However, 10 other antibodies have been identified and recently evaluated individually in IBD and especially in pediatric Crohn's disease: anti-ompC, anti-I2, anti-flagellins, anti-glycan (anti-laminaribioside carbohydrate antibodies (ALCA), anti-mannobioside carbohydrate antibodies (AMCA), anti-chitobioside carbohydrate antibody (ACCA), anti-chitin and anti-laminarin), anti-goblet cells and anti-C.albicans specific mannans antibodies. These complementary tests improve the reliability of the diagnosis. In a previous cross-sectional work on a cohort of 195 IBD patients, the investigator showed a prognostic role of some of anti-glycan Abs and especially a correlation with a pejorative form of the disease both in Crohn's disease than in Ulcerative Colitis (UC) and a prediction of corticodependency in IBD.
The PediFETCh study is a pilot trial designed to assess the feasibility of fecal microbiota transplants for the therapy of pediatric ulcerative colitis (UC) and pediatric inflammatory bowel disease-unclassified (IBD-U). Investigators will test the hypothesis that a protocol of twice-weekly retention enemas delivered over six weeks, using fecal transplant material from a healthy donor, will improve clinical and biological disease markers in patients with pediatric UC or IBD-U.
The goal of this study is to assess if oral vancomycin can restore the normal bile acid metabolism of people with Primary Sclerosing Cholangitis and Inflammatory Bowel Disease. Study participants will provide blood and stool samples in order to evaluate the bile acid metabolism before a short course of vancomycin and then again after to assess for change. The investigators will also assess the blood and stool of healthy people, and people with IBD (without PSC) as a control group.
Currently enrolling only patients with Ulcerative Colitis. Enrollment and experimental treatment of patients with Crohn's Disease stopped for a safety evaluation. This is a prospective, open label pilot study in which patients with symptoms of Inflammatory bowel disease will receive FMT therapy delivered via colonoscopy. The investigators hypothesize that FMT is a safe and effective treatment for patients with inflammatory bowel disease. The aims are: 1. To determine if symptoms of inflammatory bowel disease can be successfully treated by Fecal Microbial Transplantation. 2. To determine if endoscopic appearance of colon or ileum improves following treatment by Fecal Microbial Transplantation.
Symptoms of anxiety and depression are common in adolescents and young adults with chronic illnesses and are associated with decreased adherence to medical regimens. However, many young patients go untreated for anxiety and depression. The purpose of this study is to evaluate an online cognitive behavioral therapy (CBT) program in young adults with chronic illness. Prior research has shown online CBT to be effective in multiple other populations, but to the investigators' knowledge, this is the first study to examine web-based CBT for young adults with chronic illnesses.
Infliximab (IFX) is highly effective in inducing and maintaining remission in patients with inflammatory bowel disease (IBD). However, a large proportion of patients will eventually lose response to IFX. Therefore, strategies to improve the outcome of maintenance treatment with IFX are required. Retrospective analyses suggest that adjusting IFX treatment in order to achieve IFX trough levels (TL) above a well-defined therapeutic threshold will improve the outcome of IFX treatment.
To assess if infliximab drug levels in subjects with Ulcerative Colitis predict risk of colectomy rate. Additionally, the investigators will estimate an optimal day 4 infliximab level based on the study results.
In the study the investigators aim to test whether transcranial direct current stimulation (tDCS)-induced pain reduction is in association with functional changes in the brain measured with magnetic resonance imaging (MRI) in patients with chronic inflammatory bowel diseases (IBD). Hypothesis: Transcranial direct current stimulation can reduce the perception of pain in patients with chronic inflammatory bowel diseases, which is in association with changes in the brain measured via MRI.
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 purpose of this study is to confirm the sensitivity and specificity of the BÜHLMANN fCAL™ ELISA as an aid in diagnosis to differentiate between Inflammatory Bowel Disease (IBD; Crohn's Disease (CD), Ulcerative Colitis (UC), or indeterminate colitis) and Irritable Bowel Syndrome (IBS). To estimate the predictive value of a positive test (positive predictive value (PPV)) and the predictive value of a negative test (Negative Predictive Value (NPV)) using the proposed test outcomes for BÜHLMANN Calprotectin Test results when used in patients referred for diagnostic evaluation with signs and symptoms suggestive of either IBS or IBD. To confirm the inter-laboratory consistency of test results for the BÜHLMANN fCAL™ ELISA. To provide exploratory observations of test results in patients between the age of 2 and 21 years. To provide a sample set from normal subjects with no symptoms or signs of gastrointestinal disease for use in Expected Value Testing.
