Therapeutic equivalence should be demonstrated in a randomised, reference-controlled multicentric double blind clinical trial with PRO 160/120, a combination of Sabal- and Urtica-Extract, and Finasteride, respectively, in patients suffering from benign prostatic hyperplasia (BPH, Stage I to II according to Aiken). The study involved 543 patients, who were treated for 48 weeks with two capsules of PRO 160/120 or one capsule of Finasteride per day, in a double dummy design. Primary variable was the change of the maximum urinary flow after 24 weeks of therapy in comparison to therapy start. As secondary variables urodynamic parameters such as average urinary flow, miction volume and miction time were monitored. Urinary symptoms were recorded by the International-Prostate-Symptom-Score (I-PSS, Paris 1993). Additionally, the impacts of the symptoms on quality of life had been assessed by a quality of life questionnaire according to The American Urological Association Measurement Committee (1991). An increase of the urinary flow rate could be observed in both treatment groups (1.9 ml/s with PRO 160/ 120; 2.4 ml/s with Finasteride). During the trial, the average urinary flow increased, whereas the miction time decreased in both groups in a similar extent. The miction volume did not show any relevant differences after treatment with either PRO 160/120 or Finasteride. The I-PSS decreased from 11.3 at the therapy start to 8.2 after 24 weeks and 6.5 (week 48) under PRO 160/120 and from 11.8 to 8.0 and 6.2, under Finasteride, respectively. Accordingly, life quality improved between therapy start and therapy end from 7.5 to 4.3 with PRO 160/120 and from 7.7 to 4.1 with Finasteride. In terms of safety aspects less adverse events occurred with the Sabal/Urtica-Extract as with Finasteride. Especially less cases of diminished ejaculation volume, erectile dysfunction and headache have been reported.

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.

In this study, we evaluated the diagnostic value of symptoms of chronic polyneuropathy and to construct and validate a simple questionnaire that can help diagnose chronic polyneuropathy. In a multi-step procedure, we initially compiled a 12-item questionnaire concerning polyneuropathy symptoms. The questionnaire was completed by 117 polyneuropathy patients and 188 controls (headache, transient ischemic attack, multiple sclerosis). First, we calculated sensitivity, specificity and likelihood ratios of each symptom. Next, we used multi-variable logistic regression to create a model that could discriminate patients from controls, using only the most informative symptoms and their frequency of occurrence. Based on the regression coefficients, we developed a simple scoring system (Erasmus Polyneuropathy Symptom Score, E-PSS), which was externally validated in 140 cases with chronic idiopathic axonal polyneuropathy and 96 controls without polyneuropathy. We assessed performance with discrimination (area under the curve, AUC) and calibration analyses. Numb and tingling feet were most frequently reported by polyneuropathy patients and had the highest sensitivity. Walking on cotton wool and allodynia had the highest specificity. Logistic regression yielded a model that contained these four symptoms, complemented with balance problems and tingling hands. Based on this analysis, the E-PSS was created, ranging from 0 to 14. The E-PSS had a good performance (AUC = 0.92) in the derivation set and proved to be valid in the external population (AUC = 0.95). In conclusion, the Erasmus Polyneuropathy Symptom Score (E-PSS) is a simple, validated six-item score that takes the presence and frequency of six different symptoms into account and it may be a helpful tool to screen individuals for the presence of chronic polyneuropathy.
