Bacterial prostatitis: treatment with trimethoprim-sulfamethoxazole

Area of Science:

• Urology
• Infectious Diseases
• Pharmacology

Background:

• Chronic bacterial prostatitis is a persistent infection.
• Effective treatment remains a challenge due to potential barriers to antimicrobial penetration.

Purpose of the Study:

• To evaluate the efficacy of trimethoprim-sulfamethoxazole in treating chronic bacterial prostatitis.
• To investigate the reasons for treatment failure and recurrence.

Main Methods:

• A cohort of 15 patients with chronic bacterial prostatitis received trimethoprim-sulfamethoxazole for three months.
• Patients were followed for one to two and a half years to monitor for recurrence.

Main Results:

• A high recurrence rate of 60% was observed in patients treated with trimethoprim-sulfamethoxazole.
• Recurrence occurred despite a three-month treatment course.

Conclusions:

• Trimethoprim-sulfamethoxazole therapy for chronic bacterial prostatitis has a high failure rate.
• Factors other than poor antimicrobial diffusion into the prostate likely contribute to persistent infections.
