Correlation study of chronic nonbacterial prostatitis with the levels of COX-2 and PGE2 in prostatic secretion.

Abstract:

OBJECTIVE:The prostatitis syndrome is a multifactorial condition of largely unknown etiology. This study is to analyze the relationship between cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) with the chronic nonbacterial prostatitis (CNBP). METHODS:A total of 172 CNBP patients and 151 healthy males were recruited as CNBP and control group, respectively. The prostatic fluid was collected and tested by pre- and post-massage test. White blood cell (WBC) number was counted, and the contents of COX-2 and PGE2 were determined by double antibody-based sandwich enzyme-linked immuno-sorbent assay. The pain and discomfort of each patient were scored according to the National Institutes of Health chronic prostatitis symptom index. RESULTS:Compared with the control group, CNBP group displayed significantly higher WBC count, COX-2 level, and PGE2 level. Contents of COX-2 and PGE2 in prostatic secretion of CNBP group were positively correlated with pain scores (r = 0.855 and 0.675, respectively, P < 0.01) and total symptom scores (r = 0.674 and 0.566, respectively, P < 0.01). A significantly positive correlation between COX-2 and PGE2 levels was also discovered (r = 0.493, P < 0.05). The WBC number was not obviously correlated with the accumulations of COX-2 and PGE2 or the clinic symptoms of CNBP. CONCLUSION:Increase in PGE2 concentration caused by activated COX-2 pathway may contribute to the pain or discomfort symptom of the CNBP patients. Our results indicate that selective COX-2 inhibitors have application prospect in CNBP treatment.
