Official Title ^ICMJE

Urinary PGE-M, A Metabolite of PGE2: A Novel Biomarker of Crohn's Disease Activity

Brief Summary

The purpose of this study is to determine whether urinary PGE-M levels correlate with Crohn's disease activity and to compare how well urinary PGE-M correlates with other non-invasive biomarkers of disease activity such as C-reactive protein (CRP) and fecal calprotectin.

Detailed Description

The available clinical measures of Crohn's disease 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 Crohn's 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.
