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.
To evaluate the long-term maintenance of response, safety and tolerability of repeated administration of adalimumab in subjects with Crohn's disease who participated in and successfully completed Protocol M02-404 or Protocol M04-691.
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 this study is to evaluate the safety and effectiveness of the Adacolumn Apheresis System as a treatment for the signs and symptoms of Crohn's disease.
A follow-on safety study in subjects with Crohn's Disease who have previously been withdrawn from the double-blind study CDP870-031 [NCT00152490] or CDP870-032 [NCT00152425] due to an exacerbation of Crohn's Disease.
An open-label follow-on safety study of CDP870 (400 mg every 4 weeks) in patients with Crohn's Disease who have completed a 26-week blinded study (CDP870-031 [NCT00152490] or CDP870-032 [NCT00152425]).
A 26 week study to examine the efficacy, safety and pharmacokinetics of CDP870 in Crohn's disease
A 26 week maintenance study of CDP870 in Crohn's disease
Citrulline is an amino acid produced in the intestine and in the liver, but the liver does not contribute significantly to circulating citrulline concentrations. The intestine is thus the only organ that normally releases significant amounts of citrulline into the blood. The investigators have designed a study looking at the value of measuring plasma citrulline concentration in patients with Crohn’s disease and short bowel or normal intestinal length. Measuring the plasma citrulline concentration in short bowel patients may help to distinguish between patients who need permanent parenteral feeding from patients with just transient intestinal dysfunction. It may also help the investigators in understanding the small bowel intestinal length remaining and the absorptive integrity. In patients with normal intestinal length and Crohn’s disease, it may be a reliable marker of small bowel damage and could be applied to establish therapeutic improvements. It has been demonstrated to strongly correlate (inversely) with severity on intestinal biopsies. The investigators hypothesise that the plasma citrulline concentration is a marker for small bowel absorptive integrity and an appropriate surrogate for functional length of the small intestine. Controlled data do not yet exist to establish the place of plasma citrulline in the assessment of small bowel function in man.
