Chronic bacterial prostatitis is a bacterial infection of the prostate gland. It should be distinguished from other forms of prostatitis such as acute bacterial prostatitis and chronic pelvic pain syndrome (CPPS).
Signs and symptoms
Chronic bacterial prostatitis is a relatively rare condition — occurs in less than 5% of patients with prostate-related non-BPH lower urinary tract symptoms (LUTS) — that usually presents with an intermittent UTI-type picture and that is defined as recurrent urinary tract infections in men originating from a chronic infection in the prostate. Dr. Weidner, Professor of Medicine, Department of Urology, University of Gießen, has stated: "In studies of 656 men, we seldom found chronic bacterial prostatitis. It is truly a rare disease. Most of those were E-coli."[1] Symptoms may be completely absent until there is also bladder infection, and the most troublesome problem is usually recurrent cystitis.[2]
Diagnosis
In chronic bacterial prostatitis there are bacteria in the prostate but usually no symptoms. The prostate infection is diagnosed by culturing urine as well as prostate fluid (expressed prostatic secretions or EPS) which are obtained by the doctor doing a rectal exam and putting pressure on the prostate. If no fluid is recovered after this prostatic massage, a post massage urine should also contain any prostatic bacteria. Prostate specific antigen levels may be elevated, although there is no malignancy.
Treatment
Treatment requires prolonged courses (4-8 weeks) of antibiotics that penetrate the prostate well (β-lactams and nitrofurantoin are ineffective). These include quinolones (ciprofloxacin, levofloxacin), sulfas (Bactrim, Septra) and macrolides (erythromycin, clarithromycin). Persistent infections may be helped in 80% of patients by the use of alpha blockers (tamsulosin (Flomax), alfuzosin), or long term low dose antibiotic therapy.[3] Recurrent infections may be caused by inefficient urination (benign prostatic hypertrophy, neurogenic bladder), prostatic stones or a structural abnormality that acts as a reservoir for infection.
The addition of prostate massage to courses of antibiotics was previously proposed as being beneficial.[4][5] However, in more recent trials, this was not shown to improve outcome compared to antibiotics alone.[6]
Prognosis
Over time, the relapse rate is high, exceeding 50%. A 2007 study showed that repeated courses of combination antibiotics may eradicate infection in 83.9% of patients with clinical remission extending throughout a follow-up period of 30 months for 94% of these patients.[7]
