    • Interstitial cystitis (IC) is a chronic bladder disease for which the exact etiology is unknown and for which there is no reliably effective treatment. However, it is known that the bladder epithelium is often abnormal in IC. We discovered that normal, adult, human bladder epithelial cells are inhibited from proliferating by an anti-proliferative factor (APF) present in IC urine specimens. Inhibited proliferation may cause epithelial abnormalities characteristic of IC such as ulcerations and multiple tears in the bladder epithelium. We further discovered that levels of heparin binding—epidermal growth factor-like growth factor (HB-EGF), a factor known be important for epithelial cell proliferation and wound healing in other tissues, are abnormally low in the urine of patients suffering from IC as compared to asymptomatic controls or patients with acute bacterial cystitis. The invention herein is directed to the use of urine levels of HB-EGF as a diagnostic marker for IC.
    • 间质性膀胱炎(IC)是一种慢性膀胱疾病,其确切的病因是未知的,并且没有可靠的有效治疗。 然而,已知膀胱上皮在IC中通常是异常的。 我们发现正常,成人,人膀胱上皮细胞被IC尿液标本中存在的抗增殖因子(APF)抑制增殖。 抑制性增殖可能导致IC的特征性上皮异常,如膀胱上皮中的溃疡和多发性泪液。 我们进一步发现肝素结合表皮生长因子样生长因子(HB-EGF)的水平是已知对其他组织中的上皮细胞增殖和伤口愈合重要的因素,在IC患者的尿液中异常低 与无症状对照或急性细菌性膀胱炎患者相比。 本发明涉及使用HB-EGF的尿液水平作为IC的诊断标记物。
