[Clinical evaluation of celecoxib in treating type IIIA chronic prostatitis]

To evaluate the efficacy and safety of celecoxib in treating inflammatory(Type IIIA) chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS-IIIA type).

Sixty-four patients with diagnosed CP/CPPS-IIIA were randomized equally into two groups, Group A treated with celecoxib 200 mg daily(qd), while Group B with 200 mg twice a day(bid), both for 6 weeks. The white blood cell (WBC) count in expressed prostate secretion(EPS) and National Institutes of Health Chronic Prostatitis Symptom Index(NIH-CPSI) were assessed and compared at baseline(0 week) and at 2, 4, 6 weeks or the endpoint.

The mean number of WBC in EPS and the mean NIH-CPSI total scores were decreased gradually after treatment from baseline in both groups. The mean number of WBC of in EPS of either group at the endpoint was decreased by 46.2% and 69.4% respectively(Group A vs Group B) compared with the baseline level. The mean NIH-CPSI total scores of the two groups were decreased respectively by 5.6 and 8.3 points (Group A vs Group B). In terms of the above two parameters, Group B, responded better than Group A to the treatment. The differences observed above were statistically significant(all P < 0.05). No serious adverse event presented.

Celecoxib is effective and safe for patients with CP/CPPS(IIIA). The dosage of 200 mg twice a day is more efficacious than that of 200 mg daily.
