Filter by:Isoprostanes are compounds that are produced as a result of oxidative damage to cell membranes. Elevated tissue, serum, and urinary isoprostane levels have been described in a number of inflammatory diseases. The goal of this study is to determine utility of measuring urinary isoprostane levels in pediatric patients with inflammatory and non-inflammatory gastrointestinal disease. Urine samples will be collected from pediatric patients undergoing procedures in the Children's Hospital endoscopy unit. Clinical disease activity will be assessed using a standardized clinical disease activityiIndex. Gross endoscopic and histologic findings will be graded. Previously obtained laboratory studies will also be recorded. Urinary Isoprostane levels will be determined using a commercially available assay. Isoprostane levels will be compared across conditions (IBD vs. non-inflammatory, Crohn's disease vs. ulcerative colitis) and tested for statistical significance. Similarly, disease severity and urinary isoprostane levels will be assessed. The sensitivity, specificity, and positive and negative predictive values of elevated urinary isoprostane levels at discriminating pediatric patients with inflammatory and non-inflammatory gastrointestinal disease will be calculated.
The investigators hypothesize that PSC in children is associated with mutations and functional changes of the cystic fibrosis (CF) gene.
This randomized placebo-controlled double-blind, multi-centre trial will determine the efficacy of the probiotic VSL#3 in the prevention of Crohn's disease development following surgical resection and re-anastomosis. A total of 120 patients will be randomly assigned in a 1:1 ratio to receive VSL#3 or placebo for 90 days. Patients who respond to study treatment, as defined by the absence of a severe endoscopic recurrence at day 90, will be offered open-label VSL#3 for an additional 9 months.
The purpose of this study is to determine the influence of different 5-aminosalicylate concentrations on the metabolism of azathioprine or 6-mercaptopurine in patients with inflammatory bowel disease.
The purpose of The PROSPECT Study is to evaluate an investigational medication for the treatment of moderate to severe ulcerative colitis. This study is being conducted at up to 38 clinical research centers in the US, Canada, and Belgium, and is open to male and female patients 12 years and older. Participants in the study will have a number of visits to a research center over a five-month period. All study related care and medication is provided to qualified participants at no cost: this includes all visits, examinations, and laboratory work.
This is a multicenter, randomized, double-blind, placebo-controlled study evaluating rosiglitazone: 4 mg tablets or placebo tablets administered orally twice daily for 12 weeks. The purpose of the study is to evaluate the efficacy and safety of rosiglitazone in the treatment of mild to moderately active ulcerative colitis. Disease activity will be measured using a standard disease activity index. Calculation of the index requires patients to undergo flexible sigmoidoscopy at the start of the study and at week 12.
Colectomy with creation of an ileal pouch (IPAA) is now the treatment of choice for patients with ulcerative colitis that is resistant to existing medical therapies. The development of inflammation in these ileal reservoirs, a clinical entity referred to as pouchitis, is the most common long-term complication of this procedure and can affect 50-60% of adults and children. We have previously demonstrated that clotrimazole (delivered as a rectal suppository) is generally safe, effective, and displays poor systemic absorption when used in pediatric and adults with active pouchitis. We saw clinical benefit in patients with pouch disease that had previously failed to respond to standard antibiotic, steroid, or immunosuppressive therapies. The clinical trial outlined here will define the effectiveness and safety of topical clotrimazole therapy (delivered as a rectal enema) in pediatric (aged greater than two years) and adult patients with pouchitis. Subjects in this study will be randomly assigned to receive either placebo (no active drug, 4 subjects) or one of two clotrimazole therapy groups: 2500 mg/day (8 subjects) or 4000mg/day (8 subjects). No washout period is required, and subjects will be allowed to continue their existing anti-inflammatory medications during their participation in the study. Clotrimazole will be delivered nightly in the form of an enema. Subjects will undergo flexible sigmoidoscopy (pouchoscopy) prior to and again after completing one month of study therapy, and pouch disease activity will be graded at after each procedure using the Pouchitis Disease Activity Index (PDAI). Clinical improvement will be defined as a drop in PDAI score. If the drop in PDAI scores between placebo and either active clotrimazole treatment group is not significant, and no subject experiences what are determined to be study-related adverse effects, a second cohort of subjects will be recruited and studied after receiving one month of either placebo (4 subjects), 6000 mg/day clotrimazole (8 subjects), or 7500mg/day clotrimazole (8 subjects). Subjects will be assessed for adverse effects at the midpoint of the study. Clotrimazole blood levels will be measured during the first and last day of study participation. In addition, adults will complete a health related quality of life assessment at baseline and after completing study drug therapy. All subjects will be eligible for one month of open-label study drug therapy after completing one month of study drug therapy.
The purpose of this study is to assess the activity of multiple doses of oral rhIL-11 in patients with active Crohn's disease (Crohn's Disease Activity Index [CDAI] score from 220-400).
To explore the safety of orally delivered rhIL-11 in patients with mild to moderate left-sided ulcerative colitis. To explore the effects of orally administered rhIL-11 on pharmacogenomics in blood samples and in colonic biopsy tissue samples.
Patients with inflammatory bowel disease (IBD) who require methotrexate (MTX)for treatment currently receive this drug by injection. MTX is also available as a pill that can be given by mouth but it is not known how well the drug enters the body in patients with Crohn's disease or ulcerative colitis. This study is being done to compare how much MTX enters the body when the drug is taken by mouth compared to when it is given by injection. If the drug is well absorbed, it may allow patients to receive the drug by mouth.
