Abstract

Objective: Evaluate male patients with diagnosed chronic prostatitis, elevated serum prostate-specific antigen (PSA) to find out whether medical treatment with antibiotics and anti-inflammatory drugs can lower serum PSA, and consequently decrease the prostate cancer detection rate in patients with post-treatment PSA<4 ng/mL.

Materials and methods: This prospective study evaluated 142 male patients aged 40-73 years whose presented with elevated serum PSA>4 ng/mL and were consequently diagnosed with chronic prostatitis as expressed prostatic excretions examination revealed more than 10 white blood cells per high power field. The Patients underwent treatment with antibiotics and nonsteroidal anti-inflammatory agents for 6-weeks. Subsequently, all patients are Followed-up by serum PSA and performed transrectal ultrasonography-guided prostate biopsy within 2 months of treatment.

Results: Mean patient age was (54.4±13.5) years. The mean PSA pretreatment was (8.11±3.7) ng/mL and after treatment, the mean PSA denoted a significant decrease to (4.7±3.5) ng/mL (P=0.002). The percent of changes in mean PSA was 41.9%. Prostatic biopsy after treatment showed that, cancer prostate in 31 patients (21.8%), chronic prostatitis in 71 patients (50.7%), chronic prostatitis plus benign prostatic hyperplasia (BPH) in 31 (21.8%) and BPH in 9 patients (6.3%) With regard to PSA values, cancer prostate patients were 3/25 (12%) if PSA<2.5 ng/mL, 6/47 (12.7%) if 4.0>PSA≥2.5 and 21/70 (30%) if PSA≥4.0. The numbers of cancer prostate detected patients were 30 (21.1%).

Conclusions: Chronic prostatitis is one of the causes that elevate serum PSA levels. Treatment of chronic prostatitis with elevated PSA by antibiotics and anti-inflammatory agents can decrease the elevated PSA to the normal levels. Nevertheless, the opportunities of potential prostate cancer still exist in patients with a decreased PSA level even also if PSA<2.5 ng/mL.
