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.
This is a prospective, single country, multi-center study in participants with ulcerative colitis (UC) treated with adalimumab. Up to 147 participants are enrolled at approximately 20 sites. The baseline assessment is performed prior to the first dose of adalimumab (Visit 1). Study visits are conducted at weeks 8, 16, 24, 32, 40, 48 and 56 after baseline in accordance with clinical practice. All participants will have one Follow-up for safety approximately 70 days after the last dose of adalimumab.
Ulcerative colitis (UC) is an immune mediated chronic inflammatory bowel disease that results at least in part of an abnormal immune response to environmental factors including the intestinal microbiota. Thus, use of probiotics (microorganisms that are believed to provide health benefits when consume) may restore the gastrointestinal microbiota and reduce intestinal inflammation. Propionibacterium freudenreichii is used for the production of fermented food products (cheese). Some selected strains have strong anti-inflammatory properties. Use of cheese based on a monoxenic culture of anti-inflammatory strain of Propionibacterium freudenreichii may decrease disease activity during ulcerative colitis.
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.
Recently, Confocal Laser Endomicroscopy (CLE) has been developed as a novel technique that actually enables in vivo microscopic analysis of the gastrointestinal tract, during ongoing endoscopy. The potential role of CLE has been explored in pathology of both upper and lower gastrointestinal tract, showing good accuracy for predicting the final histopathological diagnosis, based on immediate evaluation of tissue and vascular patterns. Because of its minute scanning area, this techology is best used in conjunction with other "red-flag" techniques to screen the mucosa for areas of interest, which can then be examined by CLE for a histological diagnosis. I-scan technology (Pentax, Tokyo, Japan) is a new image-enhanced endoscopic technique that can achieve a virtual chromoendoscopy, but until now there have been no studies to determine the role of this technology in the evaluation of activity in inflammatory bowel disease. The study protocol is based on comparing imaging findings of p-CLE in conjunction with I-scan endoscopy with activity score and histological diagnosis of inflammatory bowel disease. CLE might have an important role in IBD patients management, by assessing the inflammation, dysplasia or response to treatment.
This study aims to test, if a two-week integrative therapy in an internal medicine ward will improve symptoms, disability and quality of life in patients with inflammatory bowel disease or irritable bowel syndrome.a It shall further be tested, if those changes are associated with attitudes and experiences towards complementary and alternative medicine, anxiety, depression and stress perception as well as body awareness and responsiveness.
The study examines the effect of a low FODMAP diet in patients with UC in remission but still having GI symptoms (IBS in IBD). 15 patients will be on watchful waiting. 15 patients will be on low FODMAP diet. 15 patients with recieve FODMAPs in their diet.
Video capsule endoscopy is an important procedure that can be used by doctors to find abnormalities in the small intestine, especially those that can cause bleeding. The procedure uses a tiny wireless camera to take pictures of the digestive tract. The camera sits inside a vitamin-sized capsule that a person can swallow. As the capsule travels through the digestive tract, the camera takes thousands of pictures that are transmitted to a recorder worn on a belt around a person's waist or over his/her shoulder. However, abnormalities can be missed partly because the normal dark liquids present in the intestine can prevent abnormalities from being recorded, hiding them from the physician who reviews the video. The current method used to clear these dark liquids from your small intestine is to follow a clear liquid diet and drink approximately 2 quarts of polyethylene glycol (Golytely®) the day before the video endoscopy and take simethicone (a medication used to treat symptoms of gas such as uncomfortable or painful pressure, fullness, and bloating) the morning of the test. Some of the current preparations to clear these dark liquids are not able to entirely prevent abnormalities from being missed and most have an unpleasant taste or involve drinking a lot of fluid. Linaclotide (Linzess®) is a medication approved by the Food and Drug Administration (FDA) for the treatment of constipation and irritable bowel syndrome. It is not approved by the FDA for use as an aid for clearing dark liquid from the small intestine prior to a video endoscopy. A recent presentation at a medical meeting proposed using one-dose of linaclotide (Linzess®) to improve cleansing of the small intestine for capsule endoscopy preparation to supplement fasting and clear liquid diet. This report claimed a noticeably better quality of small intestine cleansing and a 20% shorter transit time for the capsule by taking one dose of linaclotide one hour before patients swallowed the video capsule. The purpose of this study is to assess the use of one dose of linaclotide in terms of the total time it takes the capsule to move through the small bowel, and image quality as compared to the current method. The results of this study will be compared to previous patients who drank the preparation that is currently used
This study evaluates the safety and tolerability of TOP1288 rectal single and multiple ascending doses in healthy subjects and multiple doses in subjects with ulcerative colitis.
The purpose of this study is to determine whether etrasimod is a safe and effective treatment for ulcerative colitis.
