Treatment of Prostatitis
The treatment of prostatitis should be tailored to the specific type of prostatitis, with fluoroquinolones being the first-line treatment for bacterial prostatitis due to their favorable antibacterial spectrum and pharmacokinetic profile. 1
Types of Prostatitis and Diagnosis
Prostatitis is classified into several categories according to the National Institute of Diabetes, Digestive, and Kidney Diseases:
Acute Bacterial Prostatitis (ABP)
Chronic Bacterial Prostatitis (CBP)
Chronic Pelvic Pain Syndrome (Non-bacterial prostatitis)
- More common than bacterial forms
- Etiology largely unknown
Treatment Algorithms
For Acute Bacterial Prostatitis:
First-line therapy:
- Fluoroquinolones (e.g., ciprofloxacin, levofloxacin, ofloxacin)
- Consider hospitalization and IV antibiotics for patients who are systemically ill, unable to urinate voluntarily, unable to tolerate oral intake, or have risk factors for antibiotic resistance 2
- Typical IV regimens: ceftriaxone and doxycycline, ciprofloxacin, or piperacillin/tazobactam 2
Duration:
- 4 weeks of treatment 3
Additional measures:
For Chronic Bacterial Prostatitis:
First-line therapy:
For specific pathogens:
- Chlamydia trachomatis: Azithromycin 1.0-1.5 g single dose or doxycycline 100 mg twice daily for 7 days 4
- Mycoplasma genitalium: Azithromycin 500 mg on day 1, then 250 mg for 4 days; if macrolide-resistant, use moxifloxacin 400 mg daily for 7-14 days 4
- Ureaplasma urealyticum: Doxycycline 100 mg twice daily for 7 days or azithromycin 1.0-1.5 g single dose 1
Duration:
If treatment fails:
- Reassess diagnosis
- Consider long-term suppressive antibiotic therapy for recurrent bacteriuria 3
Important Considerations
- Fewer than 10% of prostatitis cases are confirmed to have bacterial infection 1
- Enterobacterales are the primary pathogens in acute bacterial prostatitis 1
- Chronic bacterial prostatitis encompasses a broader spectrum of species, including atypical microorganisms 1
- Sexual partners should be treated in cases of sexually transmitted infections 4
- Effective antibiotics must penetrate prostatic tissue and secretions (fluoroquinolones, macrolides, tetracyclines, and trimethoprim) 7, 8
Common Pitfalls to Avoid
Initiating antibiotics without proper diagnosis:
- Unless a patient presents with fever (acute prostatitis), antibiotic treatment should not be initiated immediately
- Complete appropriate investigations first, within a reasonable time period (preferably not longer than 1 week) 6
Overlooking non-bacterial causes:
- Only 10% of prostatitis cases have confirmed bacterial infection 1
- Non-bacterial prostatitis requires different management approaches
Missing prostatic abscess:
- Consider imaging in patients not responding to antibiotics 4
Inadequate treatment duration:
- Too short courses lead to recurrence
- Too long courses without reassessment lead to unnecessary antibiotic exposure
Failure to identify causative organism:
- Proper microbiological sampling is essential for targeted therapy 4
By following these evidence-based guidelines, clinicians can optimize treatment outcomes for patients with prostatitis while minimizing unnecessary antibiotic use and improving quality of life.
