Search for biomarkers aimed at improving treatment of painful bladder condition
Date:8/11/2014

Winston-Salem, N.C. August 11, 2014 Taking advantage of technology that can analyze tissue samples and measure the activity of thousands of genes at once, scientists at Wake Forest Baptist Medical Center are on a mission to better understand and treat interstitial cystitis (IC), a painful and difficult-to-diagnose bladder condition.

"We are looking for molecular biomarkers for IC, which basically means we are comparing bladder biopsy tissue from patients with suspected interstitial cystitis to patients without the disease. The goal is to identify factors that will lead to a more definitive diagnosis, and then use this information to tailor treatments to the patient," said senior author Stephen J. Walker, Ph.D., associate professor at Wake Forest Baptist's Institute for Regenerative Medicine.

The team's initial work, published online ahead of print in the Journal of Urology, found that tissue from IC patients with low bladder capacity had a significantly different gene expression profile than both IC patients with normal bladder capacity and study participants without IC. The findings suggest there may be a sub-type of IC.

"This is the first study to document functional genomic variation based solely on bladder capacity," said Robert J. Evans, M.D., a co-author and IC specialist in Wake Forest Baptist Urology. "Interstitial cystitis is notoriously difficult to diagnose. In fact, one report found that it takes the average patient eight years and seeing five doctors to be correctly diagnosed. The identification of biomarkers to improve diagnosis or treatment would be a significant breakthrough for patients and physicians."

IC, also known as bladder pain syndrome, is a condition in which the bladder lining is tender and easily irritated. Symptoms can include severe pelvic pain, urinary urgency and frequency and painful sexual intercourse. IC is often misdiagnosed as other conditions such as endometriosis, kidney ston
