Abstract

To examine the role of urinary chlamydial infection in patients with chronic prostatitis and/or chronic pelvic pain syndrome (CP-CPPS). We recruited men aged 18-55 years over 4 years. We excluded patients with acute urethritis and any acute genitourinary infections. The participants evaluated their CP-CPPS-like symptoms with the Korean version National Institutes of Health-Chronic Prostatitis Symptom Index questionnaires. We measured white blood cell (WBC) counts in expressed prostatic secretion (EPS). In-house nucleic acid amplification test for Chlamydia trachomatis and Neisseria gonorrhoeae detection and WBC counts were performed from the patient's first-voided urine. A total of 765 eligible men were classified into 3 groups: 196 in non-CP-CPPS, 410 in noninflammatory CP-CPPS, and 159 in inflammatory CP-CPPS groups. The chlamydia-infected men showed higher pain, poor quality of life (QOL), and total scores in National Institutes of Health-Chronic Prostatitis Symptom Index questionnaires than the negative men (P = .041 for pain; P = .043 for QOL, and P = .027 for total). Multivariate analysis found that urinary chlamydial infection increased the risk of WBC count ≥16 in EPS (adjusted odds ratio [OR], 2.189; 95% confidence interval [CI], 1.021-4.690; P = .044) and WBC count between 2 and 4 in urine (OR, 5.227; 95% CI, 2.503-10.918; P = .001). In addition, chlamydial infection also increased the risk of inflammatory CP-CPPS than the non-CP-CPPS group (OR, 2.448; 95% CI, 1.010-5.932; P = .044), whereas the patients with noninflammatory CP-CPPS were not affected (OR, 1.6557; 95% CI, 0.738-3.717; P = .221). Urinary chlamydial infection increased the pain scores and WBC counts in EPS and worsens the QOL in the patients with CP-CPPS.
