Abstract Background: Antibiotic prescription is a common practice in men with elevated serum prostate specific antigen. The thought is that if patients were to have a drop in, or normalization of their PSA, we can be able to avoid unnecessary prostate biopsy. The aim of this study was to evaluate the effect of ofloxacin in men with elevated PSA.Methods: 224 men with elevated PSA from the base of 4 ng/ml were enrolled in this study. Exclusion criteria were age less than 50 or greater than 75, history of allergy to fluoroquinolones, cases with history of recent prostate manipulation, men on 5 alpha reductase inhibitors, and known cases of prostate cancer. After a duration of 10 days ofloxacin 200 mg twice a day orally, PSA level was rechecked.Results: Mean age was 61.18 year. Mean PSA level before administering antibiotic was 26.3 ng/ml (-21.9 +97.4). In 120 patients (53.57%) a significant drop in serum PSA was detected so prostate biopsy was not done and in the remainder 104 patients (46.43%), Prostate biopsy was done that showed 65 adenocarcinomas of prostate and 39 benign prostate hyperplasia. Conclusions: This study showed in a patient with active urinalysis (pyuria) and normal rectal examination, trans rectal ultrasonography and prostate biopsy should be post ponded and antibiotic be started. If significant drop in serum PSA was seen, antibiotic should be continued to avoid unnecessary biopsies, otherwise, no benefit in asymptomatic men with normal urinalysis, but elevated PSA.

Background: Upgrading following prostate biopsy is very common in clinical practice. This study investigated whether the use of 5-alpha reductase inhibitors (ARI) and alpha blockers affect known clinical predictors of Gleason score upgrading or not. Materials and Methods: A retrospective study on 998 patients treated with robotic assisted laparoscopic prostatectomy for clinically localized biopsy Gleason score 6 prostate cancer were studied. The logarithm of prostate specific antigen concentration, prostate size and tumor volume were compared on the basis of the medication history of 5-ARIs and alpha blockers in the cohort of biopsy Gleason 6 patients with benign prostatic hyperplasia history, and patients whose prostate sizes fall in the top quartile. We compared known clinical and pathologic characteristics associated with upgrading in regression models with and without the addition of medications. Results: Alpha blockers, but not 5-ARI were associated with a bigger prostate. Upgrading was associated with older age (OR 1.03, 95% CI 1.01-1.06), higher BMI (OR 1.00 CI 1.01-1.08), higher log prostate specific antigen (OR 7.32, CI 3.546-15.52), smaller prostate size (OR 0.97, CI 0.96-0.98), fewer biopsy cores (OR 0.96 CI 0.92-0.99), more positive cores (OR 1.20, CI 1.08-1.34), and higher percentage of tumor at biopsy (OR 1.02, CI 1.01-1.03). Neither of the two medication classes were a significant predictor of upgrading. Medications made minimal changes in the multivariate predictive models. Conclusion: Although, alpha blockers were associate with bigger prostate size, the modulating effects of alpha blockers and 5-ARIs on common predictors of Gleason score upgrading was not significant.

Glycans of prostate-specific antigen (PSA) in prostate cancer were found to be different from that in benign disease. It is difficult to analyze heterogeneous PSA glycoforms in each individual specimen because of low protein abundance and the limitation of detection sensitivity. We developed a method for prostate cancer diagnosis based on PSA glycoforms. Specific glycoforms were screened in each clinical sample based on liquid chromatography-tandem mass spectrometry with ion accumulation. To look for potential biomarkers, normalized abundance of each glycoform in benign prostate hyperplasia (BPH) and in prostate cancer was evaluated. The PSA glycoform, Hex5HexNAc4NeuAc1dHex1, and monosialylated, sialylated, and unfucosylated glycoforms differed significantly between the prostate cancer and BPH samples. The detection sensitivity (87.5%) and specificity (60%) for prostate cancer identification are higher than those of the serum PSA marker. As low as 100 amol PSA could be detected with the ion accumulation method which has not been reported before. The improved detection specificity can help reduce unnecessary examinations.
