| Outline of Final Research Achievements |
Chronic inflammatory condition seems to be a shared characteristic in patients with interstitial cystitis (IC) and overactive bladder (OAB). Thus, we measured forty inflammatory urine markers in IC patients with or without Hunner lesions (HIC and NHIC, respectively) and OAB patients.
VEGF, IL-1α, IL-6 and chemokines including CCL2, CCL5, CXCL1, CXCL8 and CXCL10 were significantly increased in HIC and NHIC patients compared with OAB patients. The significant increases in CXCL8 and CXCL10 were also found in HIC patients compared with NHIC patients. However, there were no significant differences in the other urine markers among the groups. Area under the curves for VEGF, CXCL10, CXCL8, IL-1α, CCL5, CCL2, IL-6 and CXCL1 to detect IC in these patients were 0.87, 0.86, 0.81, 0.80, 0.80, 0.71, 0.66 and 0.50, respectively.
In conclusion, the increases in angiogenesis-associated proteins such as VEGF and CXCL10 may pathophysiologically be important for the development of IC.
