This prospective, controlled study was undertaken to evaluate the early urodynamic and symptomatic impact of the lipido-sterolic extract of Serenoa repens (Permixon(R) ) in the treatment of patients with benign prostatic hyperplasia (BPH). A total of 75 patients, aged 52-78 y with lower urinary tract symptoms due to mild/moderate BPH (mean International Prostate Symptom Score (I-PSS) 8.2) were included in the study, of which 57 received Permixon(R) 160 mg twice daily for 9 weeks. Urodynamic evaluation, including maximum urinary flow rate (Q(max)) and detrusor pressure (DP), was performed at baseline and endpoint. Prostate volume and post-void residual urine volume were assessed by transrectal and transabdominal ultrasound respectively. In addition, the I-PSS and its associated quality of life (QoL) score were determined and adverse events were recorded. Baseline parameters were comparable between the active treatment and control groups. After 9 weeks of Permixon(R) treatment Q(max) increased (6.0%, P<0.001), and there were reductions in DP at maximum flow (12.8%, P<0.001), opening DP (12.6%, P<0.001), and residual urine volume (12.6%, P<0.05). In addition, the I-PSS and QoL score both decreased significantly from baseline in the active treatment group (26.8% and 18.2% respectively, P<0.001). None of these parameters improved significantly in control patients. There were also improvements in prostate volume (2.7%) and maximum DP (5.2%) in the Permixon(R) group which did not reach significance. Three patients receiving Permixon(R) experienced gastrointestinal disturbances but these did not lead to withdrawal or require additional therapy. In patients with mild/moderate BPH, Permixon(R) treatment reduced infravesical obstruction and produced a rapid improvement in urodynamic parameters and symptoms. The drug was well tolerated. These data support the use of Permixon(R) as first-line therapy in patients with uncomplicated symptomatic BPH. Prostate Cancer and Prostatic Diseases (2000) 3, 195-199

The authors conducted a cohort study of nonsteroidal antiinflammatory drug (NSAID) use and risk of symptomatic benign prostatic hyperplasia (BPH), using data from 4,735 men without BPH at baseline in the placebo arm of the Prostate Cancer Prevention Trial (1993-2003). Incident BPH (n = 471) was defined as medical or surgical treatment or at least 2 International Prostate Symptom Score (I-PSS) values greater than or equal to 15. Proportional hazards models using time-dependent exposure for NSAID use were employed to estimate covariate-adjusted associations of NSAID-related medical conditions and NSAID use with BPH risk. Arthritis, other inflammation-related musculoskeletal conditions, and headaches were associated with increased BPH risk (hazard ratio (HR) = 1.77 (95% confidence interval (CI): 1.37, 2.29), HR = 1.57 (95% CI: 1.14, 2.17), and HR = 1.40 (95% CI: 1.09, 1.80), respectively). Use of any NSAID, use of aspirin, and use of nonaspirin NSAIDs were associated with significant increases in BPH risk (HR = 1.21 (95% CI: 1.01, 1.46), HR = 1.20 (95% CI: 1.00, 1.45), and HR = 1.34 (95% CI: 1.07, 1.69), respectively). Control for indications for NSAID use, including baseline I-PSS, attenuated the associations slightly, but all became nonsignificant. Among men with no indications for NSAID use, the hazard ratio for any NSAID use was 1.06 (95% CI: 0.82, 1.38). The modest associations of NSAID use with BPH risk in this cohort were probably due to confounding by indication, and NSAID use was not associated with BPH risk.

Lower urinary tract symptoms (LUTS) are common in older men and are frequently associated with benign prostatic hyperplasia (BPH). The relationship between BPH and endogenous total testosterone (TT) levels has been widely studied. The aim of this post hoc analysis was to determine the association between LUTS and endogenous TT levels in a subset of men participating in the 2013 Prostate Cancer Awareness Week, a U.S. community-based prostate cancer screening program. Men completed the International Prostate Symptom Score (I-PSS) questionnaire, prostate size was estimated by a digital rectal examination, and serum TT and prostate-specific antigen levels were measured. Mean TT levels (ng/dl) did not significantly correlate with prostate size category (r = +.03, p = .69): normal, 419.2 (n = 106); enlarged, 394.7 (n = 71); abnormal, 416.4 (n = 7); and abnormal/suspicious, 515.2 (n = 19). Mean TT levels (ng/dl) did not significantly correlate with I-PSS category (r = -.06, p = .40): none, 468.5 (n = 15); mild, 414.0 (n = 138); moderate, 397.4 (n = 66); and severe, 437.9 (n = 7). Mean TT levels (ng/dl) did not significantly correlate with I-PSS quality of life rating (r = -.13, p = .055): delighted, 474.5 (n = 43); pleased, 424.6 (n = 65); mostly satisfied, 361.2 (n = 63); mixed, 448.2 (n = 29); mostly dissatisfied, 337.2 (n = 17); and unhappy, 435.8 (n = 6). Adjustment for prostate size or prostate-specific antigen levels yielded similar findings. In conclusion, endogenous TT levels did not correlate with LUTS or prostate size, and these findings support the saturation theory in which TT is not able to induce further androgen-stimulated prostate tissue growth due to receptor saturation. Any worsening of LUTS following testosterone replacement therapy in hypogonadal men may be related to stimulation of prostatic cells previously deprived of testosterone.
