Clinical Trial Summary

This is a retrospective study of urine samples stored in the Beaumont BioBank for future research. The urine samples will be drawn from the urine back with patients previously diagnosed with severe interstitial cystitis (IC), mild IC and no IC.

Interstitial Cystitis (IC) also known as Painful Bladder Syndrome (PBS) is a chronic inflammatory disease. It has an unknown etiology, symptoms which present to varying degrees, as well as an uncertain natural history. Diagnosis of IC is based on symptoms after excluding more common and dangerous pathologies.


Description:

Extensive research has been done to understand the multifactorial etiology as well as to help diagnose IC. Infectious, autoimmune and anatomic causes have been looked at with few usable results. Inflammatory cells and markers have been more productive. Recently we have shown in the rat model, that chemically induced inflammation, yields temporal increases in measurable cytokines and chemokines in the urine. Moreover, this was done by Multiplex analysis, using a multiple antigen bead assay (Luminex).

Cytokines and chemokines, part of an organisms proteome, allow for looking at the function of a cell or organ at the time of the collection United States: Institutional Review Board. Urine is obtained non-invasively and yields significant information about urinary tract organs. The ability to find a biomarker or pattern of biomarker in the urine, diagnostic to a disease, offers significant advantages over serum or tissue diagnosis.

We hope to identify patterns of inflammatory markers using proteomic analysis using the previously mentioned multiple antigen cassettes (Luminex) as well as identify possible new biomarkers using a Protein Chip SELDI--TOF (surface enhanced laser desorption ionisation-time of flight) mass spectrometer. The detection of patterns or new biomarkers has promise to help with diagnosis, treatment, and ultimately revealing the etiology and course of IC.
