Purpose
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.

Experimental: 1
Fecal calprotectin and urinary PGE-M levels will be tested on all participants.
|
Procedure: Fecal calprotectin
Fecal calprotectin levels obtained and compared to urinary PGE-M and serum C-reactive protein (CRP) levels.
Procedure: Urinary PGE-M Level
Urinary PGE-M level obtained and compared to fecal calprotectin and serum CRP levels.

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 inflammatory bowel disease (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.
