Abstract
INTRODUCTION This retrospective cross-sectional observational study aimed to investigate the predictive value of the systemic immune-inflammation index (SII) for the progression of lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH). MATERIAL AND METHOD A total of 280 patients diagnosed with LUTS were analyzed, and their demographic characteristics, laboratory results, urological parameters, and SII levels were recorded retrospectively. RESULTS Clinical progression of LUTS was observed in 43.2% of the patients, with 23.9% undergoing surgery and 21.4% progressing to acute urinary retention. The study found that elevated SII levels were significantly correlated with disease progression and worse outcomes. Multivariate analysis revealed that peak urinary flow rate, erectile function scores, and platelet levels were risk factors for predicting clinical progression in LUTS/BPH patients. CONCLUSION The findings suggest that systemic inflammation and immune dysregulation play a role in BPH pathogenesis and the development of LUTS. Incorporating SII assessment into routine clinical practice could aid in risk stratification, treatment decision-making, and monitoring of disease progression in LUTS/BPH patients.

Abstract
OBJECTS To evaluate the influence of metabolic syndrome (MetS) induced by high fat diet (HFD) on prostate tissue and local inflammatory factors in rats model, and the protective efficacy of statins against pathological changes of prostate. METHODS 40 Sprague-Dawley rats were divided into 4 subgroups of normal diet (ND), HFD blank, HFD + saline and HFD + simvastatin. After the establishment of models, all subjects were killed to obtain body weight serum lipid, FBG level, FINS and HOMA-IR level. Hyperplasia level of prostate, as well as expression level of interleukin 6 (IL-6), insulin-like growth factor 1 (IGF-1), interleukin 10 (IL-10) and tumor necrosis factor alpha (TNF-α) were also measured. RESULTS Models have been successfully established. Level of serum lipid, prostatic weight, hyperplasia as well as expressions of IL-6, TNF-α and IGF-1 in the blank and saline subgroups of HFD group were higher than that of ND group (P < 0.05). While simvastatin has significantly resisted the former effects of HFD on serum lipid and prostate (P < 0.05). No significant difference in serum FBG level was found between groups and subunits. FINS levels of ND group was lower than other groups (P < 0.05). In addition, There is no significant difference in FPG and HOMA-IR levels in blank control subunit, saline control subunit, simvastatin subunit (P > 0.05). CONCLUSIONS MetS induced by HFD is an important factor in the induction of BPH. Simvastatin can alleviate the hyperplasia of prostate through the relief of local inflammation in prostatic tissue.

The Investigative Role of Statins in Ameliorating Lower Urinary Tract Symptoms (LUTS): A Systematic Review. J Clin Med 2021; 10:jcm10030416. [PMID: 33499215 PMCID: PMC7865704 DOI: 10.3390/jcm10030416] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 01/07/2021] [Accepted: 01/18/2021] [Indexed: 01/22/2023] Open
Abstract
Previous data have shown that patients with metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement (BPE) could be refractory to the medical treatment. In this context, the evidence suggests a role for statin use in LUTS/BPE patients. The present systematic review aimed to evaluate the impact of statins on the treatment of men with LUTS/BPE. This review has been registered on PROSPERO (CRD42019120729). A systematic review of English-language literature was performed up to January 2020 in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA statement) criteria. Retrieved studies had to include adults with LUTS connected to BPE treated with statins drugs for metabolic syndrome. After removing duplicates, a total of 381 studies were identified by the literature search and independently screened. Of these articles, 10 fit the inclusion criteria and were further assessed for eligibility. Data from our systematic review suggest that a long-term therapy with statins, at least 6 months, is required to achieve significant impacts on prostate tissue and LUTS. Moreover, besides statins' direct activity, the risk reduction of LUTS might be connected to the improvement of hypercholesterolemia and MetS. The role of statins for the treatment of LUTS/BPE may be beneficial; however, evidence from robust studies is not enough, and more clinical trial are required.

Abstract
OBJECTIVE To compare the efficacy of statins and ɑ blockers drug therapies for benign prostatic hyperplasia (BPH) in patients with metabolic syndrome (MetS). MATERIALS AND METHOD A total of three hundred patients were randomly distributed into three groups of one hundred patients each. Group 1 received only ɑ-adrenoceptor antagonist (ɑ-blocker, AB) (Tamsulosin), group 2 received only statin (atorvastatin), and group 3 received AB plus statin (Tamsulosin + Atorvastatin). The efficacy measurement was assessed by analyzing the changes from baseline in the total International Prostate Symptom Score (IPSS), disease-specific QoL question score and maximum urinary flow rate at the end of 6 months in each group and between the three groups. RESULTS Pre-treatment and post-treatment value of triglycerides (TG), high-density lipoprotein (HDL), and prostate volüme (PV) were not significantly different in AB group, while TG and PV were significantly lower in patients taking statin and combined therapy. The significant decrease was demonstrated in maximum urinary flow rate (Qmax) in three groups. However, the most significant decrease was observed in the combination therapy group. IPSS, postvoid residual urine volüme (PVR), and Quality of Life score (QoL) significantly changed in three groups. CONCLUSION We recommend of the use of statins in those men with BPH accompanied by MetS in which AB is ineffective alone.

Abstract
OBJECTIVE To evaluate the impacts of statin treatment on the risk of benign prostatic enlargement (BPE) progression in hyperlipidemia patients. METHODS Newly diagnosed hyperlipidemia patients (n = 7961), identified from Taiwan's National Health Insurance Research Database, were divided into four statin cohorts (statin use >365 days, n = 1604; statin use 181-365 days, n = 813; statin use 91-180 days, n = 739; and statin use 31-90 days, n = 713) and one control cohort (cohort that used no statins, n = 4092). Study endpoint was occurrence of BPE progression (BPE diagnosis plus receiving BPE-related medications or surgery). Relative risks of BPE progression in the statin cohorts compared to the control cohort were analyzed. RESULTS Multivariable Cox proportional hazards regression analyses demonstrated that BPE progression risk in the cohort used statins for >365 days was significantly lower than the control cohort (adjusted hazard ratio: 0.70, 95% confidence interval: 0.58 ∼ 0.85, p < .001). However, BPE progression risks of the other three statin cohorts did not significantly differ from the control cohort. Trend analysis revealed that the effects of statin treatment on decreasing BPE progression risk were significantly related to statin treatment duration (p = .001). CONCLUSIONS Hyperlipidemia patients with long-term statin treatment (more than 365 days) are associated with a reduced risk of BPE progression.

Abstract
Introduction The relationship between cardiovascular disease (CVD) and lower urinary tract symptoms (LUTS) is well established. A healthy lifestyle with a good quality diet and regular physical activity is important for reducing the severity of LUTS. Material and methods A literature search was performed on the subject of association between LUTS and cardiovascular risk. Results The recent data indicates that therapy for cardiovascular risk reduction might also reduce the severity of LUTS (e.g. statins reduce the risk of benign prostatic hyperplasia [BPH] and slow down the progression of LUTS in patients with hyperlipidaemia). Hypertensive patients treated with angiotensin II receptor blockers have a lower severity of LUTS. This paper shortly discusses the relationship between the occurrence of LUTS and CVD and the potential clinical implications regarding the management of the patients. Conclusions Patients with lower urinary tract symptoms require a holistic approach and cooperation of a urologist and cardiologist to diagnose concomitant cardiovascular diseases as early as possible and implement appropriate treatment. Antihypertensive, antithrombotic, hypolipemic therapies and healthy lifestyles reduce not only cardiovascular mortality, but also might reduce the severity of LUTS.

Abstract
OBJECTIVE To test the association between statin use and prostate volume (PV) change over time using data from the REduction by DUtasteride of prostate Cancer Events (REDUCE) trial, a 4-year randomised controlled trial testing dutasteride for prostate cancer chemoprevention. SUBJECTS/PATIENTS AND METHODS We identified men with a baseline negative prostate biopsy from REDUCE who did not undergo prostate surgery or develop prostate cancer over the trial period. Men reported statin use at baseline. PV was determined from transrectal ultrasonography performed to guide prostate biopsy at baseline, and 2- and 4-years after randomisation. Multivariable generalised estimating equations tested differences in PV change over time by statin use, overall and stratified by treatment arm. We tested for interactions between statins and time in association with PV using the Wald test. RESULTS Of 4106 men, 17% used statins at baseline. Baseline PV did not differ by statin use. Relative to non-users, statin users had decreasing PVs over the trial period (P = 0.027). Similar patterns were seen in the dutasteride and placebo arms, although neither reached statistical significance. The mean estimated PV was modestly but significantly lower in statin users relative to non-users in the dutasteride arm at 2-years (4.5%, P = 0.032) and 4-years (4.0%, P = 0.033), with similar (3-3.3%) but non-significant effects in the placebo arm. CONCLUSION If confirmed, our present findings support a role for statins in modestly attenuating PV growth, with a magnitude of effect in line with previously reported prostate-specific antigen-lowering effects of statins (~4%). Future studies are needed to assess whether this putative role for statins in PV growth could impact lower urinary tract symptom development or progression.

Abstract
Objective This study assessed the effect of prior statin use on the 28-day mortality of patients with type 2 diabetes mellitus (DM) who develop bloodstream infections. Methods This retrospective cohort study included all adult type 2 DM patients with bacteremia and verified prior medication history who visited the emergency department of a single tertiary hospital between January 2007 and December 2013. All major adverse consequences including septic shock events, use of mechanical ventilation, intensive care unit admission, and 28-day mortality were assessed. Results A total of 1,979 patients were enrolled in the study, of whom 507 were taking statins. Statin users had less severe disease presentation and lower levels of sepsis biomarkers such as bandemia (1.3 ± 3.1 vs 1.8 ± 4.2). After adjustment for confounding variables using a Cox regression model, only older age (adjusted hazard ratio [HR]: 1.04, 95% confidence interval [CI], 1.01–1.04), urinary tract infection (adjusted HR: 0.56, 95% CI, 0.43–0.75), and prior statin use (adjusted HR: 0.58, 95% CI: 0.42–0.85) were significantly associated with 28-day in-hospital mortality. Conclusion Prior statin treatment in patients with type 2 DM and bacteremia was associated with a lower 28-day in-hospital mortality rate.

Abstract
Non-obstructive azoospermia (NOA) severely affects male infertility, however, the deep mechanisms of this disease are rarely interpreted. In this study, we find that undifferentiated spermatogonial stem cells (SSCs) still exist in the basal compartment of the seminiferous tubules and the blood–testis barrier (BTB) formed by the interaction of neighbor Sertoli cells (SCs) is incomplete in NOA patients with spermatogenic maturation arrest. The adhesions between SCs and germ cells (GCs) are also broken in NOA patients. Meanwhile, the expression level of geranylgeranyl diphosphate synthase (Ggpps), a key enzyme in mevalonate metabolic pathway, is lower in NOA patients than that in obstructive azoospermia (OA) patients. After Ggpps deletion specifically in SCs, the mice are infertile and the phenotype of the SC-Ggpps−/− mice is similar to the NOA patients, where the BTB and the SC–GC adhesions are severely destroyed. Although SSCs are still found in the basal compartment of the seminiferous tubules, fewer mature spermatocyte and spermatid are found in SC-Ggpps−/− mice. Further examination suggests that the defect is mediated by the aberrant protein isoprenylation of RhoA and Ras family after Ggpps deletion. The exciting finding is that when the knockout mice are injected with berberine, the abnormal cell adhesions are ameliorated and spermatogenesis is partially restored. Our data suggest that the reconstruction of disrupted BTB is an effective treatment strategy for NOA patients with spermatogenic maturation arrest and hypospermatogenesis.

Abstract
BACKGROUND The aim of this meta-analysis was to understand the relationship between statin with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). METHODS A systematic literature search was conducted using PubMed, Embase, Cochrane Library, Chinese Medical and Biological Literature Database, China HowNet, Vip, and Wanfang. We calculated pooled odds ratios (OR) and 95% CI and standardized mean difference (SMD). Using Stata 12.0 and Review 5.3 for meta-analysis. RESULTS This meta-analysis included 11 articles and 49,128 participants. Results show statins could not reduce the incidence of BPH [OR = 0.77 (0.57, 1.03, P = .08]. For patients over 60 years old, statins could reduce the incidence of BPH [OR = 0.35 (0.22, 0.55), P < .0001]. Statins can slow down the progression of LUTS in BPH [SMD = -0.32 (-0.54, -0.10), P = .004], but there is no significant correlation between them in patients taking drugs for less than 1 year. CONCLUSION Statins have no significant effect on the incidence of BPH, but statins can reduce the risk of BPH for patients over 60 years old. For patients with hyperlipidemia, the duration of medication is more than 1 year, which can slow down the progression of LUTS. However, more high-quality and large sample size studies are needed to further improve and verify.

Abstract
INTRODUCTION Chronic prostatitis is one of the most common diagnoses in outpatient clinics in Urology. It is presented as a heterogeneous group of diseases, whose etiology is often unknown, showing as a common denominator a set of painful, irritative and obstructive symptoms of the genitourinary tract and perineum. OBJECTIVES A systematic review and updated meta-analysis of this pathology was performed in relation to the damages or benefits that physical activity could have in chronic prostatitis or chronic pelvic pain. METHODS The Scopus, PubMed, ScienceDirect, PEDro, The Cochrane Library, Dialnet and SciELO databases were consulted until June 2018 (the last paper used in this meta-analysis was published in March 2018). RESULTS The research team reviewed a total of 93 studies, of which 10 were selected, with a subsequent examination of their methodological quality using the PEDro scale. The comparison of the body mass index, the quality of life related to the body mass index and the correlation of the urinary incontinence were made. The overall analysis of the interventions within the urinary incontinence was significant (effect size: 0.11; 95% CI 0.038 to 0.43; P=.024). CONCLUSIONS The variability associated with experimental designs represents a heterogeneity in the effects of different programs or physical activity interventions for the treatment of chronic prostatitis. The effect sizes obtained suggest that the effectiveness of alternative treatment programs, using vehicular physical activity, may be related to the type of intervention performed.

INTRODUCTION Benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) are frequent in aging. Nonetheless, their pathogenesis is largely unknown. The androgen dependence of the first phases of prostate development have inspired the historical view that higher testosterone (T) may be involved in BPH occurrence; however, recent evidence suggests a different scenario. AIM To review the available knowledge on the pathogenesis of BPH particularly concerning the role of T and the possible connections with metabolic impairments. METHODS Relevant records were retrieved by an extensive search in Medline, including the following keywords ("testosterone"[MeSH Terms] OR "testosterone"[All Fields]) AND ("prostatic hyperplasia"[MeSH Terms] OR ("prostatic"[All Fields] AND "hyperplasia"[All Fields]) OR "prostatic hyperplasia"[All Fields] OR ("benign"[All Fields] AND "prostatic"[All Fields] AND "hyperplasia"[All Fields]) OR "benign prostatic hyperplasia"[All Fields]). There were no limitations in terms of publication date or study design. MAIN OUTCOME MEASURES Preclinical and clinical studies have been reported, with special emphasis on our contribution and interpretation. RESULTS Inflammation is a key aspect of BPH development. Along with infectious agents, prostate inflammation can be triggered by metabolic stimuli, such as dyslipidemia, an important component of metabolic syndrome (MetS). Low T and hyperestrogenism frequently occur in MetS. Mounting evidence shows that low, rather than high, T and hyperestrogenism may favor prostate inflammation. Considering these data as a whole, we postulate that BPH is the result of the action of multiple factors, which reinforce their mutual detrimental effects. CONCLUSION T is not detrimental for the prostate, and treating hypogonadism could even produce relief from LUTS and limit prostatic inflammation, which generates and maintains the process leading to BPH.

Abstract
OBJECTIVES To assess the association between triglyceride (TG)/high density lipoprotein (HDL) ratio and benign prostate hyperplasia/lower urinary tract symptoms (BPH/LUTS). METHODS Four hundred patients who were admitted to the Urology Clinic between January and December 2014 with complaints of BPH/LUTS were enrolled in this cross-sectional study. Patients were divided into two groups according to their International Prostate Symptom Score and prostate volume (PV). They were compared in terms of age, body mass index (BMI), PV, PSA, post micturional residual volume, uroflowmetry Q max value, fasting blood sugar, TG and high density lipoprotein-cholesterol (HDL-C) level and TG/HDL ratio. RESULTS Although univariate analyses reveal that age, BMI, waist circumference (WC), FBS, TG, HDL-C level, and TG/HDL ratio were correlated with PV, only age [1.125 OR (1.088-1.164), p = .00001], BMI [1.119 OR (1.040-1.204), p = .003], TG [(1.043 OR (1.016-1.071), p = .002], HDL-C [(0.923 OR (0.860-0.990), p = .025], and TG/HDL ratio [(1.224 OR (1.130-1.315), p = .014] were statistically significant in multivariate analysis. The calculated area under the curve (AUC) for PV of 30 ml, 40 ml, and 50 ml was 0.668 (0.608-0.727), 0.617 (0.561-0.673), and 0.592 (0.530-0.654), respectively. CONCLUSIONS Our results indicate that the TG/HDL ratio correlates with enhancement in PV. Further studies are warranted to better evaluate this relationship.

Abstract
Metabolic syndrome (MetS) is a cluster of metabolic abnormalities related to central adiposity and insulin resistance. Its importance is increasingly recognized as it associates with increased risks of metabolic and cardiovascular diseases. These metabolic aberrations of MetS may lead to development of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) in men. A 26.5%-55.6% prevalence of MetS in men with LUTS was reported in worldwide studies. Although the exact biological pathway is not clear yet, insulin resistance, increased visceral adiposity, sex hormone alterations and cellular inflammatory reactions played significant roles in the related pathophysiological processes. Clinician should recognize the cardiovascular and metabolic impacts of MetS in men with LUTS, early risk factors optimization and use of appropriate medical therapy may possibly alter or slower the progression of LUTS/BPH, and potentially avoid unnecessary morbidities and mortalities from cardiovascular and metabolic diseases for those men.

Abstract
AIMS This study attempted to investigate the association between lower urinary tract symptoms (LUTS) and cardiovascular disease (CVD) risk using International Prostate Symptom Score (IPSS) and CVD risk scores and to overcome the limitations of previous relevant studies. METHODS A total of 2994 ostensibly healthy males, who participated in a voluntary health check in a health promotion center from January 2010 to December 2014, were reviewed. CVD risk scores were calculated using Framingham risk score and American College of Cardiology (ACC)/American Heart Association (AHA) score. Correlation and multivariate logistic regression analysis to predict the CVD risk severity were performed. RESULTS Correlation between total IPSS with CVD risk scores demonstrated significant positive associations, which showed higher correlation with ACC/AHA score than the Framingham score (r = 0.18 vs 0.09, respectively). For ACC/AHA score, the partial correlation after adjustment of body mass index (BMI) showed significant positive correlations between all LUTS parameters and PSA. For the Framingham score, all variables, except IPSS Q2 and IPSS Q6, showed significant positive correlations. After adjustment of BMI, prostate volume and PSA, only the severe LUTS group showed significant relationship with intermediate-high CVD risk severity, as compared with normal LUTS group (OR = 2.97, 95%CI (1.35-6.99)). CONCLUSION Using two validated CVD risk calculators, we observed that LUTS is closely associated with future CVD risk. To predict the intermediate-high CVD risk severity, severe LUTS was a sentinel sign, the presence of which warrants the importance of an earlier screening for CVD.

Abstract
Clinical benign prostatic hyperplasia (BPH) is one of the most common diseases in ageing men and the most common cause of lower urinary tract symptoms (LUTS). The prevalence of BPH increases after the age of 40 years, with a prevalence of 8%-60% at age 90 years. Some data have suggested that there is decreased risk among the Asians compared to the western white population. Genetics, diet and life style may play a role here. Recent reports suggest the strong relationship of clinical BPH with metabolic syndrome and erectile dysfunction, as well as the possible role of inflammation as a cause of the prostatic hyperplasia. Lifestyle changes including exercise and diet are important strategies in controlling this common ailment.

Abstract
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. Statin use and lipid levels [total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides] were assessed at baseline. Inflammation was assessed by central review. Logistic regression was used to examine the effects of lipids and statin use on presence and extent of chronic and acute prostate inflammation [none, moderate (<20%), severe (≥20% biopsy cores)]. Chronic and acute inflammation affected 77% and 15% of men, respectively. Men with high HDL (≥60 vs. <40 mg/dL) had reduced presence of acute inflammation [OR, 0.79; 95% confidence interval (CI), 0.63-0.99] and were less likely to have severe acute inflammation (OR, 0.66; 95% CI, 0.45-0.97), but there were no other associations between lipids and inflammation. Statin users had reduced presence of chronic inflammation (OR, 0.81; 95% CI, 0.69-0.95) and were less likely to have severe chronic (OR, 0.80; 95% CI, 0.68-0.95) and severe acute inflammation (OR, 0.73; 95% CI, 0.53-1.00), relative to non-users. Given the possible role for inflammation in prostate cancer, the inverse association between statins and prostate inflammation suggests a mechanism linking statins with lower advanced prostate cancer risk.

Abstract
Background In last years Metabolic Syndrome (MetS) has been closely associated to Benign Prostatic Enlargement (BPE) Aim of our study is to evaluate the effect of MetS and each single MetS parameter on prostate growth in men surgically treated for BPE. Methods Overall, 379 men were prospectively enrolled in two tertiary referral centers. Calculated prostate volume (PV) was measured with transrectal US defining the antero-posterior (AP), the cranio-caudal (CC) and the latero-lateral (LL) diameters through the ellipsoid formula, while raw PV was calculated by suprapubic US. MetS was defined according to the NCEP-ATPIII criteria. Results One-hundred and forty men (36.9%) were affected by MetS. The number of MetS parameters (0 to 5) and the presence of MetS were correlated with the calculated PV. The number of MetS parameters were also directly related to increasing prostate diameters. At the binary logistic regression, MetS resulted associated to high (>60 cc) raw and calculated PV. Moreover, multivariate analysis suggested that AP diameter was mainly correlated with HDL cholesterol (r:-0.3103, p = 0.002) CC diameter with triglycerides (r:-0.191, p = 0.050) and LL diameter with systolic blood pressure (r:0.154, p = 0.044). However, at the binary logistic regression, only low HDL Cholesterol was the main determinant for the enlargement of all diameters and consequently of the whole PV. Conclusions Metabolic factors, specially dyslipidemia, could play a central role in the pathogenesis and progression of BPE/LUTS. Interventional studies are needed to evaluate the impact of early treatment of dyslipidemia on progression of LUTS/BPH.

Abstract
Epidemiological studies have shown that age is the principal unmodifiable risk factor of lower urinary tract symptoms (LUTS). Until the past decade, the process of lower urinary tract ageing was, therefore, considered unmodifiable - as ageing per se. However, the traditional dogma that BPH-related LUTS (BPH-LUTS) is an immutable consequence of old age is no longer acceptable. Results from multiple preclinical and clinical studies indicate that several modifiable, age-related metabolic aberrations (metabolic syndrome, obesity, dyslipidaemia, diabetes) are important determinants in both the development and the progression of BPH-LUTS. Metabolic syndrome and its related comorbidities, such as sex steroid alterations and low-grade inflammation, have been related to BPH-LUTS development and progression. With the correct treatment and recommended lifestyle changes, many individuals with metabolic syndrome might be able to prevent or delay the onset of metabolic-syndrome-related complications; however, whether promoting healthier lifestyles can really alter a man's propensity to develop BPH-LUTS remains to be clarified.

Abstract
PURPOSE The influence of cardiovascular risk factors/comorbidities on response to oral once-daily tadalafil 5 mg was explored in men with lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH). METHODS This post hoc analysis pooled data from four double-blind studies in which 1498 men with > 6-mo history of LUTS/BPH were randomised and received either once-daily placebo (n = 746) or tadalafil 5 mg (n = 752) for 12 weeks. Descriptive statistics were reported for changes in total International Prostate Symptom Score (IPSS), IPSS voiding and storage subscores, and IPSS quality-of-life (QoL) index. Treatment group differences by baseline clinical and cardiovascular factors and medical therapies were examined using analysis of covariance. RESULTS Tadalafil was effective in men with LUTS/BPH and cardiovascular risk factors/comorbidities except for patients receiving > 1 antihypertensive medication. Placebo-adjusted least squares (LS) mean improvements in total IPSS were -1.2 (95% CI: -2.5 to -0.0) in men taking > 1 antihypertensive medication vs. -3.3 (95% CI: -4.4 to -2.1) in men taking one medication (interaction p = 0.020). In addition, placebo-adjusted LS mean improvements in total IPSS were -0.2 (95% CI, -2.1 to 1.7) in men who reported use of diuretics vs. -2.8 (95% CI, -3.7 to -1.9) in men who reported taking other antihypertensive medications vs. -2.3 (95% CI, -3.2 to -1.5) in men who reported not using any antihypertensive drug (p-value for interaction = 0.053). CONCLUSIONS Once-daily tadalafil 5 mg improved LUTS/BPH, regardless of severity, in men with coexisting cardiovascular risk factors/comorbidities, except for patients with history of > 1 drug for arterial hypertension. Use of diuretics may contribute to patients' perception of a negated efficacy of tadalafil on LUTS/BPH. Comorbidities should be considered when choosing the optimal medicine to treat men with LUTS/BPH.

Abstract
INTRODUCTION Conflicting reports exist regarding the role of statins in male gonadal and sexual function. Some studies report a beneficial effect, particularly for erectile dysfunction (ED), through statins' anti-inflammatory and cardiovascular protective properties. Others suggest that statins might be associated with sexual dysfunction through negative effects on hormone levels. AIM This study aims to compare the risk of gonadal or sexual dysfunction in statin users vs. nonusers in a single-payer healthcare system. METHODS This was a retrospective cohort study of all male patients (30-85 years) enrolled in the Tricare San Antonio market. Using 79 baseline characteristics, we created a propensity score-matched cohort of statin users and nonusers. The study duration was divided into a baseline period (October 1, 2003 to September 30, 2005) to describe patient baseline characteristics, and a follow-up period (October 1, 2005 to March 1, 2012) to determine patient outcomes. Statin users were defined as those prescribed a statin for ≥3 months between October 1, 2004 and September 30, 2005. MAIN OUTCOME MEASURES Outcomes were identified as the occurrence of benign prostatic hypertrophy (BPH), ED, infertility, testicular dysfunction, or psychosexual dysfunction during the follow-up period as identified by inpatient or outpatient International Classification of Diseases, 9th Revision, Clinical Modification codes. Logistic regression was used to determine the association of statin use with patient outcomes. RESULTS Of 20,731 patients who met study criteria, we propensity score-matched 3,302 statin users with 3,302 nonusers. Statin use in men was not significantly associated with an increased or decreased risk of BPH (odds ratio [OR] 1.08; 95% confidence interval [CI] 0.97-1.19), ED (OR 1.01; 95% CI 0.90-1.13), infertility (OR 1.22; 95% CI 0.66-2.29), testicular dysfunction (OR 0.91; 95% CI 0.73-1.14), or psychosexual dysfunction (OR 1.03; 95% CI 0.94-1.14). CONCLUSIONS Statin use was not associated with increased risk of being diagnosed with gonadal or sexual dysfunction in men. Further studies using a larger sample may be needed.

Abstract
BACKGROUND Efficacy of statins has been extensively studied, with much less information reported on their unintended effects. Evidence from randomized controlled trials (RCTs) on unintended effects is often insufficient to support hypotheses generated from observational studies. We aimed to systematically assess unintended effects of statins from observational studies in general populations with comparison of the findings where possible with those derived from randomized trials. METHODS Medline (1998 to January 2012, week 3) and Embase (1998 to 2012, week 6) were searched using the standard BMJ Cohort studies filter. The search was supplemented with reference lists of all identified studies and contact with experts in the field. We included prospective studies with a sample size larger than 1,000 participants, case control (of any size) and routine health service linkage studies of over at least one year duration. Studies in subgroups of patients or follow-up of patient case series were excluded, as well as hospital-based cohort studies. RESULTS Ninety studies were identified, reporting on 48 different unintended effects. Statins were associated with lower risks of dementia and cognitive impairment, venous thrombo-embolism, fractures and pneumonia, but these findings were attenuated in analyses restricted to higher quality studies (respectively: OR 0.74 (95% CI 0.62 to 0.87); OR 0.92 (95% CI 0.81 to 1.03); OR 0.97 (95% CI 0.88 to 1.05); OR 0.92 (95% CI 0.83 to 1.02)); and marked heterogeneity of effects across studies remained. Statin use was not related to any increased risk of depression, common eye diseases, renal disorders or arthritis. There was evidence of an increased risk of myopathy, raised liver enzymes and diabetes (respectively: OR 2.63 (95% CI 1.50 to 4.61); OR 1.54 (95% CI 1.47 to 1.62); OR 1.31 (95% CI 0.99 to 1.73)). CONCLUSIONS Our systematic review and meta-analyses indicate that high quality observational data can provide relevant evidence on unintended effects of statins to add to the evidence from RCTs. The absolute excess risk of the observed harmful unintended effects of statins is very small compared to the beneficial effects of statins on major cardiovascular events.

Abstract
Dyslipidemia and chronic inflammation may play a role in the cause of lower urinary tract symptoms (LUTS) in older men. Use of statin drugs, which are prescribed to lower cholesterol and appear to reduce inflammation, may decrease the incidence or progression of LUTS. The associations of statin drug use with LUTS incidence and progression were prospectively evaluated in the Health Professionals Follow-up Study from 1992 to 2008. Hazard ratios and 95% confidence intervals of incident LUTS (from no or a low International Prostate Symptom Score (IPSS) of 0-7 to a moderate or worse IPSS of ≥15; n = 5,790 cases in 24,715 men) and of LUTS progression (from modest IPSS of 8-14 to severe IPSS of ≥20; n = 2,238 cases in 8,709 men) were calculated comparing current statin use with nonuse. The hazard ratios of LUTS incidence and progression comparing current use to nonuse were greater than 1. However, when comparisons were restricted to participants who used drugs to treat hypertension (a surrogate for uptake of medical care), statin use was not associated with LUTS incidence (hazard ratio = 1.02, 95% confidence interval: 0.94, 1.12) or progression (hazard ratio = 0.98, 95% confidence interval: 0.85, 1.13). Thus, statin use is unlikely to beneficially influence the development or course of LUTS. The present study highlights a methodological issue (confounding) that must be addressed in observational studies on the use of common drugs for indications other than the primary use.

Abstract
OBJECTIVE To explore the effects and mechanisms of simvastatin on prostate hyperplasia in spontaneously hypertensive rats (SHRs). METHODS Thirty-six male SHRs were randomly divided into three groups: the 10 and the 20 mg/kg/d simvastatin group and the control group. After 6 weeks the ultra-microscopic prostate structures were observed. The serum levels of interleukin-6 (IL-6), insulin-like growth factor (IGF-1) and angiotensin II (Ang-II) were measured by enzyme-linked immunosorbent assays. The endothelium-derived nitric oxide synthase (eNOS) expression was evaluated with immunohistochemistry. RESULTS Compared to the control group, the 20 mg/kg/d simvastatin group presented with lower absolute (p = 0.005) and relative prostate weight (p = 0.009). The basal cells and columnar cells presented with edema, condensed heterochromatin in interstitial fibroblast nuclei, widened nucleus gaps, and decreased mitochondria and endoplasmic reticulum in the 10 mg/kg/d simvastatin group, these changes were more pronounced in the 20 mg/kg/d simvastatin group. The IL-6 levels in the 10 and 20 mg/kg/d simvastatin groups were lower than those of the controls (p = 0.005 and p = 0.008). The IGF-1 levels of the 20 mg/kg/d simvastatin group were reduced compared to the control group (p = 0.016). CONCLUSIONS Simvastatin can delay and inhibit prostatic hyperplasia and progression in SHR. These actions may be mediated through the suppression of inflammatory and growth factors.

Abstract
Despite differences in design, many large epidemiological studies using well-powered multivariate analyses consistently provide overwhelming evidence of a link between erectile dysfunction (ED) and lower urinary tract symptoms (LUTS). Preclinical evidence suggests that several common pathophysiological mechanisms are involved in the development of both ED and LUTS. We recommend that patients seeking consultation for one condition should always be screened for the other condition. We propose that co-diagnosis would ensure that patient management accounts for all possible co-morbid and associated conditions. Medical, socio-demographic and lifestyle risk factors can help to inform diagnoses and should be taken into consideration during the initial consultation. Awareness of risk factors may alert physicians to patients at risk of ED or LUTS and so allow them to manage patients accordingly; early diagnosis of ED in patients with LUTS, for example, could help reduce the risk of subsequent cardiovascular disease. Prescribing physicians should be aware of the sexual adverse effects of many treatments currently recommended for LUTS; sexual function should be evaluated prior to commencement of treatment, and monitored throughout treatment to ensure that the choice of drug is appropriate.

Abstract
Lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH) are one of the most common urologic disorders in men. Accurate history-taking and focused physical examination allows us to diagnose the majority of cases. A better understanding of risk factors helps us tailor our treatment and predict outcomes more accurately. Population studies are crucial in our understanding of LUTS/BPH natural history. Temporary prostatic urethral stents that are used for the management of urinary retention may also be used for evaluation of patients with detrusor hypo-contractility. The use of ultrasound to measure intravesical prostatic protrusion (IPP) and the Doppler study for prostate capsular artery resistive index are promising. Near-infrared spectroscopy (NIRS) examines the tissue oxygenation that may be affected by bladder outlet obstruction. The mathematical algorithm needs some fine-tuning, and its reproducibility is debatable. Serum and urinary biomarkers may help us to diagnose the disorder, and more effectively monitor patients' response to therapy. Among all, IPP is clinically more applicable at this time.

Abstract
The primary cause of mortality in most developed countries is cardiovascular disease, which is the primary cause of death in the largest clinical studies of male health conditions. There are simplistic correlations between heart health and male-specific diseases. Clinicians need to motivate and provide a simplistic and realistic set of lifestyle, dietary supplement, and prescription drug recommendations to men to affect all-cause morbidity and mortality. This article provides recommendations to assist the clinician and patient to make practical changes that may be accomplished in a short period of time, and should provide tangible overall benefit for men's health.

Abstract
Benign prostatic obstruction (BPO) affects an increasing number of men with age. It can cause troublesome lower urinary tract symptoms, can have a negative impact on quality of life, and may be associated with significant morbidity. Currently available medication and surgical treatments are limited by adverse events, invasiveness, and patient compliance. This has driven research into the pathogenesis of benign prostatic hyperplasia and led to the development of novel pharmacological agents and minimally invasive therapeutic interventions. This review highlights emerging treatment options for BPO.

Abstract
Almost all aspects of urology are affected positively and negatively by certain lifestyle changes and dietary supplements. Some of these interventions have potential profound impacts independently or in combination with conventional therapy, others have no impact, and some could negatively impact treatment and overall health. The heart-healthiest recommendations have consistently served as the safest and most potentially effective options in urology from benign prostatic hyperplasia, chronic nonbacterial prostatitis, interstitial cystitis, multiple urologic cancers, male infertility, male and female sexual dysfunction, kidney stones, and Peyronie disease.

Abstract
The origins of benign prostatic diseases, such as benign prostatic hyperplasia (BPH) and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), are poorly understood. Patients suffering from benign prostatic symptoms report a substantially reduced quality of life, and the relationship between benign prostate conditions and prostate cancer is uncertain. Epidemiologic data for BPH and CP/CPPS are limited, however an apparent association between BPH symptoms and cardiovascular disease (CVD) has been consistently reported. The prostate synthesizes and stores large amounts of cholesterol and prostate tissues may be particularly sensitive to perturbations in cholesterol metabolism. Hypercholesterolemia, a major risk factor for CVD, is also a risk factor for BPH. Animal model and clinical trial findings suggest that agents that inhibit cholesterol absorption from the intestine, such as the class of compounds known as polyene macrolides, can reduce prostate gland size and improve lower urinary tract symptoms (LUTS). Observational studies indicate that cholesterol-lowering drugs reduce the risk of aggressive prostate cancer, while prostate cancer cell growth and survival pathways depend in part on cholesterol-sensitive biochemical mechanisms. Here we review the evidence that cholesterol metabolism plays a role in the incidence of benign prostate disease and we highlight possible therapeutic approaches based on this concept.

Abstract
The emergent epidemic of metabolic syndrome and its complex list of sequelae mandate a more thorough understanding of benign prostatic hyperplasia and lower urinary tract symptoms (BPH/LUTS) in the context of systemic metabolic disease. Here we discuss the nature and origins of BPH, examine its role as a component of LUTS and review retrospective clinical studies that have drawn associations between BPH/LUTS and type II diabetes, inflammation and dyslipidemia. PPARγ signaling, which sits at the nexus of systemic metabolic disease and BPH/LUTS through its regulation of inflammation and insulin resistance, is proposed as a candidate for molecular manipulation in regard to BPH/LUTS. Finally, we introduce new cell and animal models that are being used to study the consequences of obesity, diabetes and inflammation on benign prostatic growth.
