Animal data shows that testosterone administration increases the volume of some parenchymal organs. However, the effects of exogenous testosterone on solid abdominal organs in humans remain unknown. The present study evaluated the effects of testosterone administration on the volume of liver, spleen and kidneys in a dose-response trial. Young healthy men aged 18-50 years participating in the 5α-Reductase (5aR) Trial. All participants received monthly injections of 7.5 mg leuprolide acetate to suppress endogenous testosterone secretion and weekly injections of 50, 125, 300 or 600 mg of testosterone enanthate, and were randomized to receive either 2...

BACKGROUND: Although the clinical validity of risk-associated single nucleotide polymorphisms (SNPs) for assessment of disease susceptibility has been consistently established, risk reclassification from increasing numbers of implicated risk-associated SNPs raises concern that it is premature for clinical use. Our objective is to assess the degree and impact of risk reclassification with the increasing number of SNPs. METHODS: A total of 3239 patients from the Reduction by Dutasteride of Prostate Cancer Events (REDUCE) trial were included...

BACKGROUND: Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS) are common conditions. Little is known about their etiologies except that studies have suggested a substantial heritable component. Our objective is to provide a comprehensive, genome-wide evaluation of inherited risks and possible mechanisms of etiology in BPH. METHODS: We performed a three-stage, genome-wide association study (GWAS) of men from three independent populations, the REduction by DUtasteride of prostate Cancer Events (REDUCE) trial, the CLUE II cohort, and a Finnish hospital-based population...

OBJECTIVE: The aim of this study was to determine the efficacy of short-duration use of finasteride and dutasteride before transurethral resection of the prostate (TURP) on intraoperative blood loss and microvessel density (MVD) of prostate stroma and suburethral tissues in benign prostatic hyperplasia (BPH). METHODS: This study includes 450 patients who were planned for TURP. They were prospectively randomized into three groups (150 patients each). Group 1 received placebo, group 2 received finasteride, 5 mg per day, and group 3 patients received dutasteride, 0...

Background Dutasteride has been successfully used in treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). However, dutasteride inhibits 5α-reductase type 1 and type 2 enzymes and may compromises glucocorticoids and androgen metabolism and alters metabolic function resulting in undesirable metabolic and sexual adverse side effects. Aim The aim of this study was to investigate the long-term adverse effects of dutasteride therapy in men with BPH on: i) blood glucose, ii) glycated hemoglobin (HbA1c), iii) low density lipoprotein-cholesterol (LDL-C); high density lipoprotein-cholesterol (HDL-C) and total cholesterol (TC), iv) testosterone (T), v) liver alanine and aspartate aminotransferases (ALT and AST) and vi) erectile dysfunction (ED)...

Four crystalline dutasteride hydrochloride hydrate solvates containing respectively methanol, ethanol, acetone and acetonitrile molecules were obtained. All samples were characterized by extensive spectroscopic analysis with infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC) and (1)H as well as (13)C NMR techniques. For three solvates, i.e. methanol, ethanol and acetone solvates, the single crystal X-ray diffraction (SCXRD) experiments were possible, and their respective crystal and molecular structures were determined...

BACKGROUND: To evaluate whether the presence of both prostate atrophy (PA) and chronic prostate inflammation (CPI) in the same biopsy and in the same biopsy core are associated with prostate cancer (PCa) risk and grade in repeat biopsies. METHODS: Retrospective analyses of 6132 men who were 50-75 years old undergoing 2-year repeat prostate biopsy after a negative baseline biopsy for PCa in the REduction by DUtasteride of prostate Cancer Events (REDUCE) study. PA, CPI and PCa were determined by central pathology...

OBJECTIVES: To investigate changes in the Apparent Diffusion Coefficient (ADC) using diffusion-weighted imaging (DWI) in men on active surveillance for prostate cancer taking dutasteride 0.5 mg or placebo. METHODS: We analysed 37 men, randomised to 6 months of daily dutasteride (n = 18) or placebo (n = 19), undergoing 3T multi-parametric Magnetic Resonance Imaging (mpMRI) scans at baseline and 6 months. Images were reviewed blind to treatment allocation and clinical information...

PURPOSE: We compared the effects on lower urinary tract symptoms and bladder outlet obstruction of combination therapy with α1-blocker and 5α-reductase inhibitor or a switch to 5α-reductase inhibitor monotherapy. We determined the factors influencing changes in lower urinary tract symptoms after α1-blocker withdrawal. MATERIALS AND METHODS: A total of 140 outpatients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia received combination therapy with silodosin 8 mg per day and dutasteride 0...

Statin use is associated with lower advanced prostate cancer risk. In addition to cholesterol lowering, statins have systemic anti-inflammatory properties. However, their effect on histologic prostate inflammation is not well understood, particularly among men at increased prostate cancer risk but with a negative prostate biopsy. We examined associations between serum lipid levels, statin use, and histologic prostate inflammation using data from 6,655 men with a negative baseline prostate biopsy in the REduction by DUtasteride of prostate Cancer Events (REDUCE) trial...

Despite their efficacy in the treatment of benign prostatic hyperplasia, the popularity of inhibitors of 5α-reductase (5ARIs) is limited by their association with adverse sexual side effects. The aim of this study was to review and meta-analyze currently available randomized clinical trials evaluating the rate of sexual side effects in men treated with 5ARIs. An extensive Medline Embase and Cochrane search was performed including the following words: 'finasteride', 'dutasteride', 'benign prostatic hyperplasia'...

INTRODUCTION: The aim of this study was to analyze the significance of an increase in total prostate-specific antigen (PSA) serum levels despite dutasteride treatment as a predictor of prostate cancer (PC) at biopsy. We focused our attention on the rate of the first PSA increase and on the influence of prostatic inflammation. METHODS: From 2011 to 2016, 365 men with a previous negative prostate biopsy and persistent elevated PSA levels received dutasteride treatment...

PURPOSE: To determine whether decreased peak urine flow is associated with future incident lower urinary tract symptoms (LUTS) in men with mild to no LUTS. MATERIALS AND METHODS: Our population consisted of (3,140) men from the REDUCE trial with mild to no LUTS defined as an International Prostate Symptom Score (IPSS)<8. REDUCE was a randomized trial of dutasteride vs. placebo for prostate cancer prevention in men with an elevated PSA and a negative biopsy. IPSS measures were obtained every 6 months throughout the 4-year study...

BACKGROUND: High-grade prostatic intraepithelial neoplasia (HGPIN) is the precursor or premalignant form of prostate cancer. At least 30% patients with a confirmed HGPIN will develop prostate cancer within 1 year after repeated biopsy. HGPIN patients are the appropriate at-risk population for chemoprevention strategies investigation against prostate cancer. However the commonly used chemoprevention agents that targeted on hormonal imbalance or lifestyle-related factors showed varied results in HGPIN patients...

Dutasteride, used for treating benign prostate hyperplasia (BPH), promotes hair growth. To enhance delivery to the hair follicles and reduce systemic effects, in this study dutasteride has been formulated for topical application, in a nanostructured lipid carrier (NLC) coated with chitosan oligomer-stearic acid (CSO-SA). CSO-SA has been successfully synthesized, as confirmed using (1)H NMR and FTIR. Formulation of dutasteride-loaded nanostructured lipid carriers (DST-NLCs) was optimised using 2(3) full factorial design...
