Abstract

"Purpose: Chronic bacterial prostatitis is the most common urological disease in adult males, with antibiotic therapy being the gold standard for its treatment. Recent studies suggest that Chlamydia may play a role in chronic prostatitis but was difficult to prove the pathogen to the prostate. We evaluated the effect of three antibiotics (azithromycin, doxycycline, levofloxacin) in patients with chronic prostatitis of positive reaction on Chlamydial antibody. Material and Methods: The study included 54 patients who had symptoms of chronic prostatitis and proven presence of Chlamydia. The presence of Chlamydia was confirmed in expressed prostatic secretion (EPS) immediately after prostatic massage by multiplex polymerase chain reaction (PCR). The patients were randomized to receive azithromycin 1.0g (n=16) once, or doxycycline 100mg b.i.d. (n=19) for 21 days or levofloxacin 100mg t.i.d. (n=19) for 21 days. Patients’ sexual partners were treated at the same time. Clinical and bacteriological efficacy (leukocyte count, pathogen eradication rate, NIH-CPSI) was evaluated after the end of therapy. Results: After treatment of antibiotics, the leukocytes counts in the EPS was significantly decreased in all groups (p<0.05), but there was no significant difference in three groups. Also, all of groups was superior to control Chlamydia (azithromycin:doxycycline:levofloxacin=93.75%:78.94%:89.47%) and there was no significant difference of the pathogen eradication rates in three groups. The total NIH-CPSI score was significantly decreased, especially pain domain and quality of life domain (p<0.05), and there was no significant difference in three groups. Conclusions: These data suggest that antibiotics of three groups was effective to the patient with chronic prostatitis of positive reaction on Chlamydia antibody."
