PURPOSE: Prostate cancer (PCa) screening with prostate-specific antigen (PSA) reduces PCa mortality, but leads to overdiagnosis of indolent PCa. Use of 5-alpha reductase inhibitors (5-ARIs) lowers PSA and in theory could affect performance of PSA-based screening. We evaluated outcomes of PCa screening among 5-ARI users. MATERIALS AND METHODS: The study was performed within the Finnish Randomized Study of Screening for Prostate Cancer. Of 80,454 men, 31,866 were randomized to be screened at four-year intervals during 1996-2004...

The purpose of this study was to determine whether 5α-reductase inhibitors (5-ARIs) affect the discrimination between low-grade prostate cancer and benign tissues on multiparametric MRI (mpMRI). Twenty men with biopsy-proven Gleason 3 + 3 prostate cancer and 3 T mpMRI were studied. Ten patients (Tx) had been receiving 5-ARIs for at least a year at scan time. Ten untreated patients (Un) were matched to the treated cohort. For each subject two regions of interest representing cancerous and benign tissues were drawn within the peripheral zone of each prostate, MR measures evaluated, and cancer contrast versus benign (contrast = (MRTumor  - MRHealthy )/MRHealthy ) calculated...

OBJECTIVE: To evaluate the effects of short term use of finasteride and dutasteride on the amount of intraoperative blood loss and microvessel density (MVD) of prostatic stromal and suburethral tissues in the patients with benign prostatic hyperplasia (BPH) prior to transurethral resection of prostate (TURP). METHODS: The study involved 450 male patients who planned to have TURP and were prospectively randomized into 3 groups (150 patients each). Group 1 received placebo, group 2 received finasteride 5 mg/day and group 3 received dutasteride 0...

Benign prostatic hyperplasia (BPH) is an age-related phenomenon associated with prostatic enlargement and bladder outlet obstruction that can cause significant lower urinary tract symptoms (LUTS). These LUTS have a negative impact on an individual's quality of life, which is why treatment of symptomatic BPH has become a major priority. Although surgical interventions exist for treating BPH, pharmacological therapies are often preferred due to their minimal invasiveness and high degree of effectiveness. The three classes of drugs approved for treating BPH include α-blockers, 5-α-reductase inhibitors (5-ARIs) and phosphodiesterase 5 (PDE-5) inhibitors...

BACKGROUND: Previous studies have suggested a greater benefit for various outcomes in men diagnosed with benign prostatic hyperplasia (BPH) who are treated with dutasteride than for men treated with finasteride. This study investigates whether the rates of BPH-related prostate surgery and acute urinary retention (AUR) differ between dutasteride and finasteride users in the Netherlands. METHODS: From the PHARMO Database Network, men aged ≥50 years with a dispensing of dutasteride or finasteride with or without concomitant alpha-blocker treatment between March 1, 2003 and December 31, 2011 were selected...

Lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO) represent one of the most common clinical complaints in adult men. Several drugs used for LUTS/BPO may strongly affect sexual function and bother. The aim of this systematic review and meta-analysis was to evaluate the impact of combination therapy with alpha-blockers (AB), 5-alpha reductase inhibitors (5-ARI) on the risk of erectile dysfunction(ED) and libido alterations (LA) from randomized clinical trial (RCT). Based on the inclusion and exclusion criteria, five RCTs involving 6131 patients were included in the analysis...

Prevention is an important treatment strategy for diminishing prostate cancer morbidity and mortality and is applicable to both early- and late-stage disease. There are three basic classifications of cancer prevention: primary (prevention of incident disease), secondary (identification and treatment of preclinical disease), and tertiary (prevention of progression or recurrence). Based on level I evidence, 5-alpha reductase inhibitors (5-ARIs) should be considered in selected men to prevent incident prostate cancer...

Randomized clinical trials have shown that use of 5α-reductase inhibitors (5-ARIs) lowers overall prostate cancer (PCa) risk compared to placebo, while the proportion of Gleason 8-10 tumors is elevated. It is unknown whether this affects PCa-specific survival. We studied disease-specific survival by 5-ARI usage in a cohort of 6,537 prostate cancer cases diagnosed in the Finnish Prostate Cancer Screening Trial and linked to the national prescription database for information on medication use. Cox proportional hazards regression was used to estimate hazard ratios and 95% confidence intervals for prostate cancer-specific deaths...

Treatment-induced sexual dysfunctions (SD) are a recurrent and controversial topic in recent literature on the adverse events related to the use of 5-alpha-reductase inhibitors (5ARIs) (1, 2). In order to deal adequately with the various aspects of this topic, it is necessary to first cover some of the steps that allow a better definition and understanding of the subject.

UNLABELLED: Sexual dysfunction is a potential side effect of BPH (benign prostatic hyperplasia) and LUTS (lower urinary tract symptoms) drugs: this article is a critical review of the current literature. Many studies have been published on this topic. Methodological flaws limit the conclusions of these studies, mainly because of the lack of diagnostic criteria for ejaculatory and sexual desire dysfunction. Few of these studies are RCTs. The α-blocker (also called α1-adrenergic antagonist, alpha-adrenoceptor antagonist, alpha-blocker or AB) and 5-ARI (also called 5α-reductase inhibitor or testosterone-5-alpha reductase inhibitor) drugs can in particular cause erectile dysfunction, ejaculatory disorders and reduction of sexual desire...

BACKGROUND: Lower urinary tract symptoms are common among older men and 5-α reductase inhibitors (5-ARI) are a group of drugs recommended in treating these symptoms. The effect on prostate volume is mediated by a reduction in dihydrotestosterone; however, this reduction is counterbalanced by a 25% rise in serum testosterone levels. Therefore, 5-ARI use might have systemic effects and differentially affect bone mineral density, muscular mass and strength, as well as falls, all of which are major determinants of fractures in older men...

Vagal nerve stimulation (VNS) has been shown to have antiarrhythmic effects, but many of these benefits were demonstrated in the setting of vagal nerve decentralization. The purpose of this study was to evaluate the role of afferent fiber activation during VNS on efferent control of cardiac hemodynamic and electrophysiological parameters. In 37 pigs a 56-electrode sock was placed over the ventricles to record local activation recovery intervals (ARIs), a surrogate of action potential duration. In 12 of 37 animals atropine was given systemically...

Formerly preeclamptic women are at risk for cardiovascular disease. Low plasma volume may reflect latent hypertension and potentially links preeclampsia with chronic cardiovascular disease. We hypothesized that low plasma volume in normotensive formerly preeclamptic women predisposes to hypertension. We longitudinally studied n=104 formerly preeclamptic women in whom plasma volume was measured 3 to 30 months after the preeclamptic pregnancy. Cardiovascular variables were assessed at 2 points in time (3-30 months postpartum and 2-5 years thereafter)...
