Active clinical trials for "Inflammatory Bowel Diseases"

RATIONALE: A substantial proportion of children and teenagers with suspected inflammatory bowel disease (IBD) referred for endoscopy do not have the disease. The investigators designed a clinical decision rule that included a calprotectin stool test to discern which patients require further investigations. The accuracy of this diagnostic strategy is 88.5% with a low risk of missing IBD cases. Although the number of negative endoscopies was reduced after introduction of this strategy, still 22% of the referred children and teenagers underwent an unnecessary invasive test. S100A12 (calgranulin C) is a cytoplasmic protein secreted exclusively by activated neutrophils and this stool marker may be more IBD-specific than calprotectin. OBJECTIVE: To determine whether the specificity of S100A12 is superior to the specificity of calprotectin without sacrificing sensitivity HYPOTHESIS: Inclusion of the calgranulin C stool test will improve the specificity of the screening-strategy.

Physical activity (PA) is beneficial in the prevention and management of chronic disease. However, few data exist regarding the level of PA in inflammatory bowel disease (IBD) and whether or not vigorous PA may have beneficial effects on patients' health. To evaluate the level of PA and the effect of PA on disease activity of patients with IBD. To evaluate the effect of PA on quality of life of patients with IBD.

Evaluation of the efficacy of laser-based endomicroscopy as a complement to white-light colonoscopy and chromoendoscopy for early detection of colon dysplasia in patients with PSC-IBD. White-light colonoscopy is a routinely used procedure in colorectal cancer surveillance programs. However, it does not permit detection of early dysplastic lesions. Chromoendoscopy by applying a dye (indigo-carmine) through the colonoscope helps to identify flat lesions but is not suitable for accurate endoscopic diagnosis of dysplasia and intraepithelial neoplasia Under this aim we will perform a clinical study evaluating a newly developed technique allowing for in vivo confocal microscopy assessment of the colon mucosa using laser-based endomicroscopy together with intravenous administration of fluorescein (FITC).

Inflammatory Bowel Diseases (IBD) are life-long, incurable illnesses that can have a profound effect on the patients quality of life. Disease education is a corner stone of IBD care to enable patients to take up an active role in their disease management. While patient education is enshrined in the IBD standards, actual patient knowledge is often poor.3 Knowledge is not associated with the level of the patient's educational achievement, but member of patient organisations such as Crohn's and Colitis UK (CCUK) have significantly better knowledge than non-members. This may highlight the positive effects of education offered by CCUK, but it is also conceivable that patients with a greater interest in their disease are more like to join organisations like CCUK. Different sources of patient information may therefore influence what level of disease related knowledge a patient achieves. Apart from high quality clinical information provided by professional organisation (British Society of Gastroenterology, European Crohn's and Colitis Organisation), the National Health Service and charities (CORE, CCUK), there is also a host of unregulated information available. The emerging dominance of the internet for information gathering has provided easy access for patients to a host of websites providing information on IBD. A number of these provide alternative (not evidence based) views, which could have a potentially negative impact on patient's knowledge. Furthermore patients often share their stories on internet forums and it is likely that those stories share are more likely to represent the extreme ends of disease rather than those experienced by the majority. This could potentially cause anxiety in patients with IBD. The quality of information found on the internet varies widely and up to 50% of websites have been judged as poor. The vast majority of patients with IBD have access to the internet and more than half use to search for health related information.7 We have previously also demonstrated that patients with anxiety have better disease related knowledge of IBD.

The purpose of this study is to determine whether inflammatory bowel disease in children involve the respiratory tract as expressed by increased levels of the Fraction of exhaled Nitric Oxide (FeNO) and spirometry.

The objective and aims of this study is to develop The University of California Irvine Medical Center Inflammatory Bowel Disease Research Registry for the purpose of: Performance of retrospective studies on inflammatory bowel disease to assess disease outcomes and response to therapy. Obtaining permission from the Research Registry participants to be contacted by members of The University of California Irvine Medical Center Inflammatory Bowel Disease Research Center to identify patients that may be eligible for participation in future research studies. Performance of studies to quantify disease phenotypes and treatment patterns.

Fecal calprotectin is a very sensitive non-invasive inflammation marker in the detection of inflammatory bowel disease and, to a lesser degree, has also proven to be useful in adenomatous polyps, neoplasias, and infectious gastroenteritis. Elevated calprotectin levels can also be found in patients with lesion only in the upper gastrointestinal tract. However, the diagnostic value of calprotectin has never been tested in this setting. The aim of the study is therefore to determine the diagnostic value of fecal calprotectin in patients with diseases of the upper gastrointestinal tract.

What is known? the impact of AZA, immunomodulatory drug widely used in active CD, on the intestinal wall differs from those of steroids, what is reflected in the significant difference in the postoperative anastomotic leaks rate AZA inhibits intestinal epithelial cell growth by inducing the apoptosis and inhibiting proliferation of intestinal epithelial cells in in vitro studies What is new? The effect of AZA on cellular damage was assessed in humans' study AZA increases cell apoptosis in the intestinal epithelium of active CD patients, much stronger than steroids AZA actively promotes the DNA damage repair in the intestinal epithelium; the steroid effect, even when combined with AZA, is not so pronounced The intensity of proliferative processes, in contrast to steroids, is significantly inhibited in response to AZA The disintegration of the mucosa layer in response to AZA is observed The difference in the mechanisms of action of AZA and steroids on the intestinal mucosa may be directly related to the reported difference in the risk of septic postoperative complications, but this requires further research

Differential diagnosis between Ulcerative Colitis (UC) and Crohn's disease (CD) is of pivotal importance for the management of Inflammatory Bowel Disease (IBD) as both entities involve specific therapeutic management strategies. Confocal Laser Endomicroscopy (CLE) allows on demand in vivo characterization of architectural and cellular details during endoscopy. Here, we assessed the efficacy of CLE to differentiate between UC and CD.

This is a post-marketing observational study of patients with Inflammatory Bowel Disease (specifically, Crohn's disease or Ulcerative Colitis) who have been prescribed CT-P13 (infliximab) or Remicade (infliximab) for treatment. CT-P13 (brand names Inflectra and Remsima) is a biosimilar medicine to Remicade, meaning it is a biologic medicine that contains the same active substance as Remicade (infliximab). The key study objectives are as follows: To characterize the population and drug utilization patterns of patients treated with CT-P13 for Crohn's Disease (CD) or Ulcerative Colitis (UC) in the context of standard of care Remicade To explore the long-term safety profile of CT-P13 in the treatment of patients with CD or UC in the context of standard of care Remicade To assess the effectiveness of CT-P13 in the treatment of patients with CD or UC in the context of standard of care Remicade
