Abstract

BACKGROUND: Mounting worldwide resistance trends make the use of fluoroquinolone (FQ) antibacterial agents increasingly difficult. This is felt more acutely in the case of urogenital infections, which are mainly caused by Gram-negative pathogens. For years, levofloxacin and other FQs have been the first-line drugs for treating National Institutes of Health (NIH) category II chronic bacteria prostatitis (CBP). Eradication rates achieved by levofloxacin in the frame of randomized trials vary greatly, ranging between 71 and 86%.

OBJECTIVES: This was a retrospective observational study to investigate the efficacy of levofloxacin against CBP in a real-life setting (urological outpatient wards).

METHODS: A database including the clinical records of >2,500 CBP patients was reviewed. Patients were selected based on strict inclusion criteria. They were treated for 4 weeks with 500 mg levofloxacin per day, alone or combined with other antibacterials. Besides standard urological procedures including the 4-glass test for pathogen isolation, international symptom questionnaires (the NIH Chronic Prostatitis Symptom Index [NIH-CPSI] and International Prostate Symptom Score [IPSS]) were administered.

RESULTS: Pathogen eradication was achieved in 79% of the cases treated with levofloxacin as a single agent and 87.8% of patients who received a combination of levofloxacin and azithromycin. The 11% increase in the eradication rate in the latter group is statistically significant. In addition,…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 2,500 participants or records.
