A Study to Determine Whether Urinary PGE-M Levels Correlate With Ulcerative Colitis Disease
- Conditions
- Ulcerative Colitis
- Interventions
- Procedure: Urinary PGEm levelProcedure: fecal calprotectin
- Registration Number
- NCT00409396
- Lead Sponsor
- Vanderbilt University
- Brief Summary
The purpose of this study is to determine whether urinary PGE-M levels correlate with Ulcerative Colitis Disease activity and to compare how well urinary PGEm correlates with other noninvasive biomarkers of disease activity such as CRP and fecal calprotectin.
- Detailed Description
The available clinical measures of ulcerative colitis activity can be overly influenced by functional symptoms. Placebo response rates in clinical trials are high. Several non-invasive biomarkers are currently available for assessing IBD disease activity including erythrocyte sedimentation rate, c-reactive protein and fecal calprotectin. Although these markers hold some promise, their performance is less than ideal. what is needed is a simple, non-invasive biologic measure of UC disease.
Cyclooxygenase-2 (COX-2) is involved in prostaglandin E2 (PGE2) synthesis and is expressed in epithelial inflammatory conditions and some cancers. We have developed an assay to quantify the major urinary metabolite of PGE2, PGE-M. PGE-M has been previously shown to be elevated in the urine of patients with advanced colorectal neoplasia relative to controls. We recently showed that PGEm was a sensitive and specific marker of Crohn's disease activity (Accepted for publication at DDW 2006).
