Project description:Interstitial cystitis (IC) and bladder pain syndrome are terms used to describe a heterogenous chronic pelvic and bladder pain disorder of unknown etiology. The goal of this pilot study was to determine if gene expression profiling of bladder biopsy tissue from patients experiencing symptoms could be used to separate the patients based on some clinical parameter. Gene expression profiles in bladder biopsy tissue from patients with: (1) low bladder capacity (defined here as <400 ml upon hydordistension), (2) normal capacity (M-bM-^IM-%400 ml), and (3) controls were compared. Gene expression profiles from low bladder capacity tissues differed significantly from normal capacity and control tissue, suggesting gene expression profiling may be a useful tool for better understanding IC disease pathophysiology.

Project description:Interstitial cystitis (IC)/bladder pain syndrome (BPS) is a clinical condition that manifests as a sensory hypersensitivity of unknown cause and is characterized by urinary frequency, bladder discomfort, and pelvic pain. In the present volatolomic study, we have analyzed the VOCs unique to urine specimens obtained from interstitial cystitis patients, in compassion to healthy controls.This is the novel finding from comprehensive and unbiased metabolomics analysis that urinary menthol is decreased in urine specimens from IC patients, and that the reduced menthol level in IC is potentially linked to the chronic inflammation, which is often observed in IC patients
Project description:Interstitial cystitis (IC) is a progressive chronic bladder disease with an increasing incidence. Today, IC is diagnosed by subjective symptoms in combination with cystoscopic and histologic evidence. The ultimate goal is the development of a diagnostic assay for IC on a molecular level. A comparative gene expression profile of bladder biopsies from patients with IC and control patients identified candidate marker genes for IC. Experiment Overall Design: Five IC patients and six control patients ('healthy') have been selected for the study. All IC patients had Hunner's ulcers and, with the exception of one person, also glomerulations, whereas the control group did not show these cystoscopic findings. From each IC patient two biopsies have been taken, one from an ulcerated area of the bladder ('ulcus'), and one from an area that macroscopically looked 'normal', 'not-inflamed' or not hyperemic ('ni'). One 'ni' sample has been excluded from the study because it had an expression pattern similar to the healthy controls.
Project description:Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic and debilitating pain disorder of the bladder and urinary tract with poorly understood etiology. A definitive diagnosis of IC/BPS can be challenging because many symptoms of IC/BPS are shared with other urological disorders. An analysis of urine presents an attractive and non-invasive resource for monitoring and diagnosing IC/BPS. Here, a non-targeted LC-MS and LC-MS/MS-based peptidomics analysis of urine samples collected from IC/BPS patients were compared to urine samples from asymptomatic controls.
