The objective of this NIH-specific substudy is immunologic monitoring of cytokine and immune cell responses in subjects undergoing treatment with AIN457 (human monoclonal anti-human interleukin-17A) for moderate to severe Crohn's disease. Recent data suggests that interleukin-17 (IL-17) is an important mediator of inflammation in certain animal models of Crohn's disease, and treatment aimed at blocking the IL-23-IL-17 axis can ameliorate the inflammatory changes. In addition, elevated expression of IL-l7 has been found in the gut tissue of patients with active Crohn's disease. This substudy will measure changes in cytokine production, relevant RNA expression, and immune cell populations (in the periphery and lamina propria) for correlation with clinical outcomes in order to explore the mechanisms of therapeutic response.
The dimension of diagnostic procedures and therapy of chronic inflammatory bowel diseases largely depends on the degree of mucosal inflammation. Video colonoscopy is currently the gold standard in the evaluation of the mucosa in patients with Ulcerative Colitis (UC). PillCam Colon Capsule was developed by Given Imaging, Israel, as possible alternative imaging modality to evaluate mucosal changes in patients with UC. The colonic mucosa can be visualized and recorded by video while the colon capsule passes the colon. Many patients suffering from UC ask their physician for possible alternative diagnostic imaging because they are uncomfortable with conventional colonoscopy. The primary aim of the present study is to compare the new Pillcam Colon Capsule with standard colonoscopy with respect to assessing mucosal disease activity and localization of inflamed colonic mucosa in patients with known UC.
The purpose of this study is to evaluate if the combination of oral budesonide and rectal hydrocortisone improves symptoms in patients with active ulcerative colitis. Also, we would like to determine if oral budesonide and rectal hydrocortisone has fewer and less severe side effects compared to standard steroids (prednisone).
Ulcerative colitis is an inflammatory bowel disease that afflicts up to one million people in the U.S. Symptoms include rectal urgency, bloody diarrhea, moderate to severe abdominal pain, fever, and fatigue. Melatonin is a hormone that is associated with sleep and other body functions that may be related to health. Melatonin is produced in the pineal gland and, in fact, it is produced in even greater amounts in the gut. Melatonin appears to be important in gastrointestinal tract physiology and health, and data from cell and animal experiments, and some studies in humans, suggest that supplemental melatonin may help ameliorate colitis. Given that current treatments for ulcerative colitis are not always effective, and often have serious side effects, there is considerable interest in finding alternative treatments for this disease. However, experimental data on the ability of melatonin to improve ulcerative colitis in humans are lacking. To address this, we plan to conduct a pilot clinical trial (60 adult male and female participants) that will obtain preliminary data about the effectiveness of melatonin supplementation as a treatment for ulcerative colitis in adult men and women with the disease.

Ulcerative colitis is a chronic inflammatory bowel disease caused by an imbalance between natural defence mechanisms in the intestinal mucosa and microbes in the intestinal lumen. We hypothesise that an improvement or even normalisation of this balance may be achieved by the use of vaccines and dietary oats. The combined use of oral typhoid vaccine and cholera/ETEC-vaccine is supposed to stimulate mucosal defence factors, while dietary oats modifies the microbial environment inside the intestinal lumen. Or study aim is to show if such treatment brings symptom relief to patients with ulcerative colitis.
This study will involve the use of a new compound, SB-656933. Accumulation of inflammatory white blood cells (mostly polymorphonuclear neutrophils)in the gut (colon) may be contributing to the pathology of ulcerative colitis. It has been shown that SB-656933 reduces polymorphonuclear neutrophils (PMN) accumulation in pre-clinical models of colitis. 99m-Tc-HMPAO scintigraphy is a imaging technique which will be used in this study to observe the effect of SB656933 on the migration of PMN to inflamed tissue.
The purpose of this study is to evaluate the efficacy of the addition of GMA apheresis to steroid conventional treatment for achieving and maintaining remission in Active steroid dependant Ulcerative Colitis patients
This is a confirmatory, multicentric, prospective, randomized, controlled, single-blind study in subjects with long standing ulcerative colitis in clinical remission with indication for surveillance colonoscopy. The patients are examined with the PENTAX EC-3870CIFK and EC-3870CILK confocal colonoscopes either by chromoscopy-guided endomicroscopy with targeted biopsies or by standard endoscopy with random and targeted biopsies. The aim is to investigate whether chromoscopy-guided endomicroscopy has a higher sensitivity than standard endoscopy with respect to detection of intraepithelial neoplasia (IN) and to compare the proportion of patients with at least 1 IN detected by chromoscopy-guided endomicroscopy versus standard endoscopy.
The metabolic response to ulcerative colitis, including increased proteolysis and lipolysis and changes in energy expenditure, plays a significant role in the resulting malnutrition from which these patients suffer. Tumor necrosis factor-alpha (TNF-alpha), a pro-inflammatory cytokine, has been found to be elevated in children with ulcerative colitis. TNF-alpha has been incriminated in the mechanism of weight loss in many different chronic diseases, and causes net protein and lipid catabolism. Anti-TNF-alpha antibody (infliximab) has been proven to be an effective therapy for ulcerative colitis. The purpose of this study is to determine changes in protein and lipid metabolism, as well as resting energy expenditure, before and after therapy with anti-TNF-alpha antibody (infliximab) in children with ulcerative colitis. Performing this study will better define the changes in nutrition status observed in these children following remission of active ulcerative colitis, and potentially lead to changes in medical and nutritional management of these children
