A Study to Determine the Role of Toll-like Receptor-4 Expression in Patients With Interstitial Cystitis/Bladder Pain Syndrome

2016-08-17 10:53:22 | BioPortfolio


This is a prospective pilot study, with a recruitment goal of 60 patients. Patients who are female, above the age of 18, and with a diagnosis of IC/BPS based on clinical criteria and O'Leary Sant ICPI and ICSI scores undergoing cystoscopy, hydrodistention and bladder biopsy will be included. The bladder biopsies will be evaluated for TLR4 expression, and sent for histological assessment of mast cell count. Additionally, data will be collected at baseline, day of surgery, day 7, day 14 and day 28. Data will include validated questionnaires, lower urinary tract symptoms, and recorded pain medication use.

Medical and Biotech [MESH] Definitions

A condition with recurring discomfort or pain in the URINARY BLADDER and the surrounding pelvic region without an identifiable disease. Severity of pain in interstitial cystitis varies greatly and often is accompanied by increased urination frequency and urgency.

Inflammation of the URINARY BLADDER, either from bacterial or non-bacterial causes. Cystitis is usually associated with painful urination (dysuria), increased frequency, urgency, and suprapubic pain.

A HERNIA-like condition in which the weakened pelvic muscles cause the URINARY BLADDER to drop from its normal position. Fallen urinary bladder is more common in females with the bladder dropping into the VAGINA and less common in males with the bladder dropping into the SCROTUM.

Endoscopic examination, therapy or surgery of the urinary bladder.

Involuntary discharge of URINE as a result of physical activities that increase abdominal pressure on the URINARY BLADDER without detrusor contraction or overdistended bladder. The subtypes are classified by the degree of leakage, descent and opening of the bladder neck and URETHRA without bladder contraction, and sphincter deficiency.
