Effects of high-intensity statin therapy on steroid hormones and vitamin D in type 2 diabetic men: A prospective self-controlled study. Lipids 2024. [PMID: 38764377 DOI: 10.1002/lipd.12399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 05/07/2024] [Accepted: 05/07/2024] [Indexed: 05/21/2024]
Abstract
The study aimed to assess the effect of high-intensity statin therapy on testicular and adrenal steroids and vitamin D levels in type 2 diabetic men. A prospective study, conducted between March 2021 and July 2022, including 60 men with type 2 diabetes, aged 40-65 years, statin-free, and in whom treatment with high-intensity statin was indicated. The patients had two visits, before and 6 months after a daily intake of 40 mg of atorvastatin. During each visit, they underwent a clinical examination, and a fasting blood sample was collected for biological and hormonal measurements. There was a significant increase in the prevalence of decreased libido (from 22% to 47%, p = 0.001) and a significant decrease in the frequency of sexual intercourse (from 4 [1-8] to 3 [0-4] per month, p = 0.005). The median ADAM's score significantly increased (from 4 [2-7] to 6 [3-8], p = 0.000). Twenty-two percent of the patients developed gynecomastia. The median total, bioavailable and free testosterone significantly decreased from 15.1 (11.4-17.4), 6.3 (5.0-7.8), and 0.27 (0.22-0.33) nmol/L to 12.7 (10.7-15.9), 5.7 (4.4-7.0), and 0.24 (0.19-0.30) nmol/L, respectively, with no change in FSH and LH levels. Three patients (5%) developed hypogonadism (testosterone <8 nmol/L). There was a significant decrease in DHEAS from 4.5 (2.8-6.1) to 3.8 μmol/L (2.6-5.6) and no change in cortisol and vitamin D levels. High-intensity statin therapy decreased androgen levels in type 2 diabetic men with significant clinical impact.

Abstract
Lipid metabolism plays a key role in erectile dysfunction. Our purpose was to evaluate the influence of lipid-lowering drugs on erectile dysfunction employing a two-sample Mendelian randomization (MR) study. Genetic instruments were employed to represent the exposure of lipid-lowering drugs. Inverse variance-weighted MR (IVWMR) was employed to calculate the estimation of effects. IVW-MR analysis showed that the positive relationship between the expression of HMGCR and the risk of erectile dysfunction (odds ratio [OR] = 1.27, 95% confidence interval [CI] 1.03-1.57; p = 0.028). No significant relationship was detected between NPC1L1, PSK9 expression and erectile dysfunction. This MR study suggested that HMGCR inhibitors are a more desirable treatment modality for patients with ED.

Abstract
BACKGROUND Erectile dysfunction (ED) is common after radical prostatectomy (RP) due to cavernous nerve damage. Risk of ED is also affected by vascular function. Statins prevent vascular events but their association with post-prostatectomy ED is unclear. We explored the likelihood of starting ED treatment after RP by statin use at the population level. METHODS The study cohort included 14,295 prostate cancer (PCa) patients with no ED treatment prior to diagnosis of PCa treated with RP in Finland during 1995-2013. Information on use of cholesterol-lowering drugs and ED medication during 1995-2014 and penile prosthesis implantation during 1996-2014 were gathered from national registries. Risk of ED treatment initiation after RP was analyzed by pre-diagnostic and post-diagnostic statin and non-statin cholesterol lowering (NSCL) drug use with Cox regression model. RESULTS Pre-diagnostic statin use or NSCL drug use overall had no association with risk of ED treatment initiation after RP. Post-diagnostic statin use was associated with a slightly increased risk of initiation of any ED treatment (HR = 1.07; 95% CI = 1.01-1.14). Patients with the longest duration of post-diagnostic statin use had a significantly decreased risk of PDE5 inhibitor initiation compared to non-users (HR = 0.43; 95% CI = 0.20-0.94). Among patients with no cardiovascular comorbidities, pre-diagnostic statin users had a significantly increased risk of initiation of injectable ED drugs (HR = 1.27; 95% CI = 1.04-1.55), however, no association with risk of any other ED treatment was observed. CONCLUSION Statin users have a slightly increased risk of ED treatment initiation after RP, which probably reflects the effect of the underlying vascular insufficiency.

Abstract
Diabetes mellitus (DM), a chronic metabolic disease characterised by elevated levels of blood glucose, is among the most common chronic diseases. The incidence and prevalence of DM have been increasing over the years. The complications of DM represent a serious health problem. The long-term complications include macroangiopathy, microangiopathy and neuropathy as well as sexual dysfunction (SD) in both men and women. Erectile dysfunction (ED) has been considered the most important SD in men with DM. The prevalence of ED is approximately 3.5-fold higher in men with DM than in those without DM. Common risk factors for the development of DM and its complications include sedentary lifestyle, overweight/obesity and increased caloric consumption. Although lifestyle changes may help improve sexual function, specific treatments are often needed. This study aims to review the definition and prevalence of ED in DM, the impact of DM complications and DM treatment on ED and, finally, the current and emerging therapies for ED in patients with DM.

Abstract
BACKGROUND Diabetes is a major risk factor for erectile dysfunction, however, the effect of GLP-1 receptor agonists on erectile dysfunction is unknown. We aimed to assess the incidence, prevalence, and progression of erectile dysfunction in men treated with dulaglutide compared with placebo, and to determine whether dulaglutide's effect on erectile dysfunction was consistent with its effect on other diabetes-related outcomes. METHODS The Researching Cardiovascular Events with a Weekly Incretin in Diabetes (REWIND) trial was a double-blind, placebo-controlled randomised trial of the effect of dulaglutide on cardiovascular outcomes. REWIND was done at 371 sites in 24 countries. Men and women aged older than 50 years with type 2 diabetes, who had either a previous cardiovascular event or cardiovascular risk factors, were randomly assigned (1:1) to receive either dulaglutide or placebo. Participating men were offered the opportunity to complete the standardised International Index of Erectile Function (IIEF) questionnaire at baseline, 2 years, 5 years, and study end. We did an exploratory analysis, in which we included participants who completed a baseline and at least 1 follow-up IIEF questionnaire. The primary outcome for these analyses was the first occurrence of moderate or severe erectile dysfunction following randomisation, assessed by the erectile function subscores on IIEF. This analysis was part of the REWIND trial, which is registered with ClinicalTrials.gov, NCT01394952. FINDINGS Between Aug 18, 2011, and Aug 14, 2013, 3725 (70·1%) of 5312 male participants with a mean age of 65·5 years (SD 6·4 years) were analysed, of whom 1487 (39·9%) had a history of cardiovascular disease, and 2104 (56·5%) had moderate or severe erectile dysfunction at baseline. The incidence of erectile dysfunction following randomisation was 21·3 per 100 person-years in the dulaglutide group and 22·0 per 100 person-years in the placebo group (HR 0·92, 95% CI 0·85-0·99, p=0·021). Men in the dulaglutide group also had a lesser fall in erectile function subscore compared with the placebo group, with a least square mean difference of 0·61 (95% CI 0·18-1·05, p=0·006). INTERPRETATION Long-term use of dulaglutide might reduce the incidence of moderate or severe erectile dysfunction in men with type 2 diabetes. FUNDING Eli Lilly and Company.

Abstract
BACKGROUND Erectile dysfunction (ED) is a major health problem that affects a significant proportion of the general population, and its prevalence is even higher in patients with CV risk factors and/or disease. ED and cardiovascular (CV) disease share several common pathophysiological mechanisms, and thus, the potential role of ED as a predictor of CV events has emerged as a significant research aspect. OBJECTIVE The purpose of this review is to present and critically discuss data assessing the relation between ED and CV disease and the potential predictive value of ED for CV events. METHODS A comprehensive review of the literature has been performed to identify studies evaluating the association between ED and CV disease. RESULTS Several cross-sectional and prospective studies have examined the association between ED and CV disease and found an increased prevalence of ED in patients with CV disease. ED was shown to independently predict future CV events. Importantly, ED was found to precede the development of overt coronary artery disease (CAD) by 3 to 5 years, offering a "time window" to properly manage these patients before the clinical manifestation of CAD. Phosphodiesterase type 5 inhibitors are the first-line treatment option for ED and were shown to be safe in terms of CV events in patients with and without CV disease. CONCLUSION Accumulating evidence supports a strong predictive role of ED for CV events. Early identification of ED could allow for the optimal management of these patients to reduce the risk for a CV event to occur.

Abstract
Familial hypercholesterolemia (FH) subjects have high low-density lipoprotein cholesterol (LDL-C) and may be at high risk of erectile dysfunction and atherosclerotic cardiovascular diseases. We evaluated the effect of PCSK9-i on sexual function evaluated by the Male Sexual Health Questionnaire (MSHQ) and the International Index of Erectile Function (IIEF-5) questionnaire and on pulse wave velocity (PWV) in FH male subjects. In this prospective observational study, we evaluated 30 FH male patients on high-intensity statins plus ezetimibe and with an LDL-C off-target. All patients added PCSK9-i treatment and obtained clinical assessment at baseline and after six months of PCSK9-i. As expected, LDL-C significantly decreased after adding-on PCSK9-i (-48.73%, p < 0.001). MSHQ and PWV significantly improved after adding-on PCSK9-i (for MSHQ 93.63 ± 6.28 vs. 105.41 ± 5.86, p < 0.05; for PWV 9.86 ± 1.51 vs. 7.7 ± 1.42, p < 0.05); no significant change of IIEF-5 was found. Finally, a simple regression showed that ∆ MSHQ was significantly associated with ∆ LDL-C and ∆ PWV (p value for both <0.05). In conclusion, PCSK9-i therapy significantly improves lipid profile, PWV, and sexual function in FH male patients; our results support the favorable function of PCSK9-i on these parameters.

Abstract
The aim of this study is to present a summary of current evidence concerning the various treatments in the management of penile rehabilitation after radical prostatectomy (RP) and provide recommendations for future research. Randomized controlled trials (RCTs) were identified from electronic databases including PubMed, the Cochrane Library, Embase, and Web of Science from inception through March 2020 with no limitation to language. Comparable data from each study were combined in a meta-analysis where possible, otherwise data were synthesized narratively. The data analysis was completed by Review Manager version 5.3. A total of 39 RCTs were included in this study. At present, phosphodiesterase type 5 inhibitors (PDE5is) remain the first-line treatment for patients with erectile dysfunction (ED) after RP. Compared with the placebo group, patients in regular PDE5is group (mean difference (MD): 0.76; 95% confidence interval (CI): 1.69-4.44; p < 0.0001) and on demand group (MD: 3.92; 95% CI: 2.95-4.88; p < 0.00001) had a significantly higher mean Erectile Function domain of the International Index of Erectile Function (IIEF-EF) scores within 3 months after RP. As for the proportion of IIEF-EF ≥ 22, patients in regular PDE5is group and on demand PDE5is group had significantly higher proportion than those in placebo group 6 months after RP, and the odds ratios were 1.87 (95% CI: 1.32-2.66; p = 0.0005) and 2.17 (95% CI: 1.20-3.93; p = 0.01), respectively. No significant difference was observed between regular PDE5is group and on demand group regardless of mean IIEF-EF score or the proportion of IIEF-EF ≥ 22. Intracorporeal injection therapy seemed to have similar efficacy to PDE5is. The International Index of Erectile Function-5 items (IIEF-5) scores were significantly higher in vacuum constriction devices group than control group at 6-9 months after RP (MD: 6.70, 95% CI: 2.30-11.10, p = 0.003) with great between-study heterogeneity (p = 0.06, I2 = 72%). The other therapeutics including low-intensity extracorporeal shockwave therapy, statin therapy, psychotherapy interventions, and pelvic floor muscle training plus electrical stimulation showed certain improvement on erectile function. We found that the combination therapy showed certain advantages over monotherapy. Currently, PDE5is-based combination therapy remains the mainstream treatment for ED after RP. Intracorporeal injection therapy and vacuum therapy could be served as alternative treatments if PDE5is are ineffective and contraindicated.

Abstract
Abstract
Aims
Erectile dysfunction is associated with increased risk of cardiovascular disease; however, little is known about patients seeking treatment for erectile dysfunction. This study investigated the risk of cardiovascular disease for patients receiving medication for erectile dysfunction.
Methods and results
This nationwide cohort study included 71,710 men aged 40–80 years receiving their first erectile dysfunction medication from 2000 to 2012. Their adjusted risk of cardiovascular events in time intervals after the first erectile dysfunction medication was compared to the general male population using multivariate Poisson regression models and was expressed as a risk ratio (RR). The risk for overall cardiovascular disease was decreased in the first 3 years: the RR in the first year was 0.92 (95% confidence interval [CI] 0.87–0.97, p = 0.003; incidence: 23.68 per 1000 patient-years), and after 1–3 years the RR was 0.94 (95% CI 0.90–0.97, p = 0.002; incidence: 24.92 per 1000 patient-years). After 3 years, there was no significant difference. The risk of myocardial infarction was decreased in all time intervals: the RR in the first year was 0.60 (95% CI 0.50–0.73, p < 0.001; incidence: 1.82 per 1000 patient-years), after 1–3 years the RR was 0.72 (95% CI 0.63–0.82, p < 0.001; incidence: 2.16 per 1000 patient-years) and after 3 years the RR was 0.80 (95% CI 0.73–0.88, p < 0.001; incidence: 2.25 per 1000 patient-years). The risk of heart failure was decreased in the first 3 years.
Conclusion
Receiving medication for erectile dysfunction was associated with a decreased risk of myocardial infarction and cardiovascular diseases for the first 3 years.

Abstract
One in 4 Americans >40 years of age takes a statin to reduce the risk of myocardial infarction, ischemic stroke, and other complications of atherosclerotic disease. The most effective statins produce a mean reduction in low-density lipoprotein cholesterol of 55% to 60% at the maximum dosage, and 6 of the 7 marketed statins are available in generic form, which makes them affordable for most patients. Primarily using data from randomized controlled trials, supplemented with observational data where necessary, this scientific statement provides a comprehensive review of statin safety and tolerability. The review covers the general patient population, as well as demographic subgroups, including the elderly, children, pregnant women, East Asians, and patients with specific conditions such as chronic disease of the kidney and liver, human immunodeficiency viral infection, and organ transplants. The risk of statin-induced serious muscle injury, including rhabdomyolysis, is <0.1%, and the risk of serious hepatotoxicity is ≈0.001%. The risk of statin-induced newly diagnosed diabetes mellitus is ≈0.2% per year of treatment, depending on the underlying risk of diabetes mellitus in the population studied. In patients with cerebrovascular disease, statins possibly increase the risk of hemorrhagic stroke; however, they clearly produce a greater reduction in the risk of atherothrombotic stroke and thus total stroke, as well as other cardiovascular events. There is no convincing evidence for a causal relationship between statins and cancer, cataracts, cognitive dysfunction, peripheral neuropathy, erectile dysfunction, or tendonitis. In US clinical practices, roughly 10% of patients stop taking a statin because of subjective complaints, most commonly muscle symptoms without raised creatine kinase. In contrast, in randomized clinical trials, the difference in the incidence of muscle symptoms without significantly raised creatinine kinase in statin-treated compared with placebo-treated participants is <1%, and it is even smaller (0.1%) for patients who discontinued treatment because of such muscle symptoms. This suggests that muscle symptoms are usually not caused by pharmacological effects of the statin. Restarting statin therapy in these patients can be challenging, but it is important, especially in patients at high risk of cardiovascular events, for whom prevention of these events is a priority. Overall, in patients for whom statin treatment is recommended by current guidelines, the benefits greatly outweigh the risks.

Abstract
Objective Statins inhibit the 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase enzyme and thus reduce plasma cholesterol levels. Although decreased cholesterol level is the main target of anti-lipidemic drugs, cholesterol has an important role in the synthesis of lipid-based hormones such as testosterone. In this study, the alterations in serum testosterone levels were examined in rats under atorvastatin therapy and their responses to vitamin D, infliximab, and leflunomide supplementation were evaluated. Materials and Methods Wistar rats were treated with atorvastatin (100 mg/kg) for 21 days to induce inhibition of the HMG-CoA reductase enzyme activity. Following statin therapy, rats received vitamin D (0.2 μg/kg/day) orally for 15 days, infliximab (7 mg/kg/day) intraperitoneally in two doses, or leflunomide (10 mg/kg/day) orally in two doses. Subsequently, the alterations in serum testosterone levels were measured by ELISA. Results Atorvastatin led to a decrease in the testosterone level compared to the vehicle group. Administration of vitamin D, infliximab, and leflunomide under HMG-CoA inhibition insignificantly increased the testosterone level compared to the atorvastatin control group. Furthermore, it appears that rats under statin administration respond better to treatment with leflunomide by achieving a greater induction in testosterone levels than with vitamin D or infliximab. Conclusion Our data provide evidence that administration of vitamin D, infliximab, and leflunomide in rats under atorvastatin treatment may ameliorate the serum testosterone levels.

Abstract
INTRODUCTION Sexual dysfunction in men is common, and optimal treatment is complex. Although several systematic reviews concerning treatment approaches exist, a comprehensive overview without limitations concerning the population, interventions, or outcomes is lacking. AIM To conduct a "review of reviews" to compare the effectiveness of pharmacologic, non-pharmacologic, and combined interventions. METHODS 9 electronic databases, relevant journals, and reference lists up to July 2018 were searched. For each intervention, only the most recent and comprehensive meta-analysis or systematic review was included. The methodologic quality of the reviews was appraised using the Assessment of Multiple Systematic Reviews-2 tool. MAIN OUTCOME MEASURE Sexual functioning (via intravaginal ejaculatory latency time and international index of erectile function), sexual satisfaction, and adverse effects. RESULTS 30 systematic reviews were included. For premature ejaculation, several treatments, including oral pharmacotherapy (selective serotonin inhibitors, phosphodiesterase type 5 [PDE5] inhibitors, tricyclic antidepressants, and opioid analgesics), topical anesthetics, and combined drug and behavioral therapies demonstrated significant improvements of 1-5 minutes in the intravaginal ejaculatory latency time. Pharmacologic interventions (PDE5 inhibitors, penile injection, and testosterone), shockwave therapy, lifestyle modifications, and combined therapies (PDE5 inhibitors and psychological intervention) were effective in treating erectile dysfunction. Most pharmacologic therapies were associated with adverse effects. CONCLUSIONS There is suggestive evidence that pharmacologic interventions or combined therapies are more effective than non-pharmacologic interventions for treating sexual dysfunction in men; however, a range of treatment options should be presented to individual patients so they may consider the risks and benefits of treatments differently. Evidence related to behavioral and psychological interventions is insufficient compared with that related to drug trials, highlighting the necessity for larger and better randomized controlled trials.

Abstract
This study focused on analysis of current publications evaluating safety of lipid-lowering therapy. Search for literature was performed on websites of cardiological societies and online databases, including PubMed, EMBASE, and eLibrary by the following key words: statins, statin intolerance, lipid-lowering therapy, statin safety, and statin аdverse effects. The focus is on statins, in view of the fact that they are the most commonly prescribed, highly effective and safe drugs for primary and secondary cardiovascular prophylaxis. This review consistently summarized information about myopathies, hepatic and renal dysfunction, potentiation of DM, and other possible adverse effects of lipid-lowering therapy. The author concluded that despite the high safety of statins acknowledged by all international cardiological societies, practicing doctors still continue unreasonably cancel statins, exposing the patient under even greater danger.

Abstract
Despite many advances over the last few decades, cardiovascular disease (CVD) remains the leading cause of death globally, with men afflicted at an earlier age than women. In a bid to reduce the global burden of morbidity and mortality due to CVD, emphasis has been placed on prevention, particularly on widespread promotion of ideal cardiovascular health behaviors and advancing strategies to identify and treat high-risk individuals who may benefit from aggressive preventive therapy. Erectile dysfunction is a highly prevalent condition that has been demonstrated to share the same risk factors as clinical CVD, and to have independent predictive value for future CVD events. Importantly, subclinical atherosclerosis appears to precede vascular ED by a decade or longer, with ED preceding clinical CVD such as myocardial infarction and stroke in temporal sequence by about 2-5 years. Crucially, since ED may represent the first presentation of otherwise "healthy" men to care providers, a clinical diagnosis of vascular ED may represent a unique opportunity to identify high risk individuals, intervene, and thus prevent progression to clinical CVD. This review summarizes up-to-date evidence of the relationship between ED and subclinical and clinical CVD, and details the position of current guidelines and clinical recommendations on the role of ED assessment in CVD prevention. Finally, this review proposes a clinical framework for the incorporation of ED into standard CVD risk assessment in middle-age men.

Abstract
OBJECTIVE Case reports have suggested an increased risk of gynecomastia with HMG-CoA reductase inhibitors (ie, statins). A recent meta-analysis also found that statins decrease circulating testosterone levels in men. We investigated whether statin use was associated with an increased risk of gynecomastia. DESIGN Case-control study. PATIENTS A cohort of patients from a random sample of 9 053 240 US subjects from the PharMetrics Plus™ health claims database from 2006 to 2016 was created. MEASUREMENTS New cases of gynecomastia requiring at least two ICD-9 codes were identified from the cohort and matched to 10 controls by follow-up time and age using density-based sampling. Rate ratios (RRs) for users of statins were computed using conditional logistic regression adjusting for alcoholic cirrhosis, hyperthyroidism, testicular cancer, Klinefelter syndrome, obesity, hypogonadism, hyperprolactinemia and use of spironolactone, ketoconazole, H2 receptor antagonists (H2 blockers), risperidone, testosterone and androgen deprivation therapy. RESULTS Our cohort included 6147 cases of gynecomastia and 61 470 corresponding matched controls. The adjusted RR for current, recent and past statin use with respect to gynecomastia was 1.19 (1.04-1.36), 1.38 (1.15-1.65) and 1.20 (1.03-1.40), respectively. CONCLUSIONS Statin use is associated with an increased risk of developing gynecomastia. Clinicians should be cognizant of this effect and educate patients accordingly.

Abstract
Phosphodiesterase type 5 inhibitors (PDE5Is) are the drug of choice for medical management of erectile dysfunction (ED). On-demand PDE5Is have an overall efficacy of 60-70% for ED; 30-35% of patients fail to respond to a PDE5I, and 30-50% of non-responders can be salvaged with detailed counseling on proper use and physician follow-up to ensure that the patient has been prescribed an appropriate and full PDE5I clinical trial. True non-responders may be offered intracavernosal injections of erectogenic drugs, intraurethral alprostadil, or surgical insertion of a penile prosthesis. Such options are not discreet and are associated with more adverse effects than PDE5Is. Thus patients may request additional non-invasive medical management options. This review describes published literature on patients who failed to respond to an on-demand PDE5I regimen and were treated with a non-invasive PDEI-based regimen, including switching from one PDE5I to another; increasing the dose of PDE5I above the labeled dosage range; using two PDE5Is concurrently; using a daily PDE5I regimen; or combining a PDE5I with a testosterone supplement, α-adrenergic antagonist, intraurethral or intracavernosal alprostadil, vacuum erection device, or low-intensity shock wave therapy. The limitations of published clinical trials do not allow for sufficient evidence to recommend one option over another. Therefore, in PDE5I-refractory patients, the choice of a specific next step should be individualized based on the preference of the patient and his sexual partner, the advantages and disadvantages of the various options, the concurrent medical illnesses and medications of the patient, and the patient's response to treatment.

Abstract
Erectile dysfunction (ED) is associated with cardiovascular disease (CVD) and CVD mortality. However, the relationship between ED and subclinical CVD is less clear. We synthesized the available data on the association of ED and measures of subclinical CVD. We searched multiple databases for published literature on studies examining the association of ED and measures of subclinical CVD across four domains: endothelial dysfunction measured by flow-mediated dilation (FMD), carotid intima–media thickness (cIMT), coronary artery calcification (CAC), and other measures of vascular function such as the ankle–brachial index, toe–brachial index, and pulse wave velocity. We conducted random effects meta-analysis and meta-regression on studies that examined an ED relationship with FMD (15 studies; 2025 participants) and cIMT (12 studies; 1264 participants). ED was associated with a 2.64 percentage-point reduction in FMD compared to those without ED (95% CI: –3.12, −2.15). Persons with ED also had a 0.09-mm (95% CI: 0.06, 0.12) higher cIMT than those without ED. In subgroup meta-analyses, the mean age of the study population, study quality, ED assessment questionnaire (IIEF-5 or IIEF-15), or the publication date did not significantly affect the relationship between ED and cIMT or between ED and FMD. The results for the association of ED and CAC were inconclusive. In conclusion, this study confirms an association between ED and subclinical CVD and may shed additional light on the shared mechanisms between ED and CVD, underscoring the importance of aggressive CVD risk assessment and management in persons with ED.

Abstract
PURPOSE OF REVIEW We review the recent literature on the hypothesized temporal relationship between subclinical cardiovascular disease (CVD), vascular erectile dysfunction (ED), and clinical CVD. In addition, we combine emerging research with expert consensus guidelines such as The Princeton Consensus III to provide a preventive cardiologist's perspective toward an ideal approach to evaluating and managing CVD and ED risk in patients. RECENT FINDINGS Development of ED was found to occur during the progression from subclinical CVD to clinical CVD. A strong association was observed between subclinical CVD as assessed by coronary artery calcium (CAC) and carotid plaque and subsequent ED, providing evidence for the role of subclinical CVD in predicting ED. ED is also identified as a substantial independent risk factor for overt clinical CVD, and ED symptoms may precede CVD symptoms by 2-3 years. SUMMARY Given the body of evidence on the relationship between subclinical CVD, ED, and clinical CVD we recommend that all men with vascular ED should undergo cardiovascular risk assessment. We further recommend using CAC scores for advanced risk assessment in patients at low-intermediate to intermediate risk (5-20% CVD risk), with risk driving subsequent lifestyle and pharmacologic treatment decisions.

Abstract
The classification of knowledge is essential for understanding between researchers and the advancement of science. In this article a brief classification of clinical research methods is presented. The advantages that researchers use the same nomenclature are recalled, which enables improved communication among researchers, facilitates replication of studies and searches in databases, and helps to establish the aspects that can affect the different research models. They are grouped into four broad categories: epidemiological articles, articles of qualitative methodology, mixed methodology articles and review articles.

Park J, Kwon OS, Cho SY, Paick JS, Kim SW. Chronic administration of atorvastatin could partially ameliorate erectile function in streptozotocin-induced diabetic rats. PLoS One 2017; 12:e0172751. [PMID: 28245261 PMCID: PMC5330475 DOI: 10.1371/journal.pone.0172751] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2016] [Accepted: 02/04/2017] [Indexed: 01/17/2023] Open
Abstract
The efficacy of statins is related to the ‘common soil’ hypothesis, which proposes oxidative stress and inflammation as main pathophysiologic processes in the disease group of diabetes and endothelial dysfunction. This study evaluated the recovery of erectile function after administration of chronic statin alone in streptozotocin (STZ)-induced diabetes mellitus (DM) rats, focusing on the anti-oxidative effects and consequentially recuperated endothelial function. A total of 45 male Sprague-Dawley rats (8 weeks old) were divided into three groups (n = 15 each): an age-matched normal control group (Control group), an uncontrolled DM group (DM group), and a statin-treated group (Statin group). The rats in the DM and Statin group received an injection of STZ (60 mg/kg). Beginning 10 weeks after the establishment of DM, the Statin group received daily treatment with atorvastatin (10 mg/kg) via oral gavage for four weeks. After 14 weeks, the results of the experiment were evaluated. The ratios of intracavernosal pressure (ICP) to mean arterial pressure (MAP) were recorded with cavernosometry (20 Hz, 3 V, 0.2 msec for 30 seconds) before and after the intravenous administration of udenafil (1 mg/kg). Expression of alpha-smooth muscle actin (α-SMA) was evaluated using cavernosal tissue. In addition, changes in RhoA translocation ratio and myosin phosphatase target subunit 1 (MYPT1) phosphorylation were evaluated with western blot. Superoxide dismutase (SOD) and malondialdehyde (MDA) levels were also analyzed as measurements of oxidative stress levels. The ICP/MAP and area under the curve (AUC)/MAP ratios of the Statin group were obviously superior to the DM group, but were not comparable to the Control group (P<0.001). The level of oxidative stress, namely SOD activity, was also significantly lower in the Statin group than in the DM group (P = 0.015), and was comparable to the Control group. In contrast, MDA levels were not considerably different among the groups (P = 0.217). The RhoA translocation ratio was not significantly different among the groups (P = 0.668), whereas MYPT1 phosphorylation in the Statin group was significantly lower than in the DM group (P = 0.030), and similar to the Control group. Expression of α-SMA in the Statin group was higher than in the DM group (P<0.001), and comparable to the Control group. Chronic statin treatment alone showed anti-oxidative effects and helped to restore the erectile mechanism, but did not lead to the full recovery of erectile function in STZ-induced DM rats. Therefore, combination therapy rather than a single agent should be the preferred treatment strategy for DM-associated erectile dysfunction, especially in the setting of severe diabetes.

Abstract
An increasing amount of data supports an inverse association between statin use and cancer risk. The findings for prostate cancer, particularly advanced disease, are the most promising of all cancers studied. Use of these agents seems to also be associated with improved prostate- cancer-specific survival, particularly in men undergoing radiotherapy, suggesting usefulness of statins in secondary and tertiary prevention. Some study results might be influenced by increased PSA screening and health-conscious behaviour in statin users but these factors are unlikely to completely account for observed beneficial effects. The epidemiological evidence is supported by preclinical studies that show that statins directly inhibit prostate cancer development and progression in cell-based and animal-based models. The antineoplastic effect of statins might arise from a number of cholesterol-mediated and non-cholesterol-mediated mechanisms that affect pathways essential for cancer formation and progression. Understanding these mechanisms is instrumental in drug discovery research for the development of future prostate cancer therapeutics, as well as in designing clinical trials to test a role for statins in prostate cancer prevention. Currently, sufficient data are lacking to support the use of statins for the primary prevention of prostate cancer and further research is clearly warranted. Secondary and tertiary prevention trials in men who have been diagnosed with prostate cancer might soon be performed.

Sexual Dysfunction in Type 2 Diabetes at Diagnosis: Progression over Time and Drug and Non-Drug Correlated Factors. PLoS One 2016; 11:e0157915. [PMID: 27706160 PMCID: PMC5051725 DOI: 10.1371/journal.pone.0157915] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2015] [Accepted: 06/07/2016] [Indexed: 01/10/2023] Open
Abstract
Aims To present the longitudinal data of the SUBITO-DE study, a prospective survey involving male patients with new or recently diagnosed type 2 diabetes mellitus (T2DM) (<24 months). Materials and Methods Sexual function was assessed in male patients with T2DM at baseline (phase 1) and after a mean follow-up of 18 months (phase 2). Standard metabolic parameters and sexual and depressive symptoms were evaluated. Results Six of the 499 enrolled patients died of different causes during phase 1. Of the 493 surviving men invited to participate in phase 2, 450 (mean age 59.0±9.0 years) (90.2%) accepted and 43 (8.2%) were lost to follow-up. As compared to baseline, the proportion of the men who reported improvement in erectile dysfunction (ED) at follow-up was nearly double that of the men who reported worsening of ED (22.6% vs. 12.8%). The increase in frequency of sexual activity the men reported at follow-up assessment indicates that many never treated before baseline were taking an ED drug during the study period (106 subjects). Phosphodiesterase type 5 inhibitors (PDE5i) were the ED drugs most commonly taken at both baseline and follow-up. An overall improvement over baseline values was observed in metabolic targets for T2DM and depressive symptoms. Conversely, no change in lifestyle behaviors was recorded during the study. Conclusions Sexual dysfunction is a major concern in men with T2DM. The SUBITO-DE study demonstrates that, when combined with adequate counseling and tailored PDE5i therapy, an integrated approach to achieving metabolic targets in men with T2DM can improve sexual function as well as depressive symptoms.

Abstract
Erectile dysfunction (ED) is prevalent among men and its presence is often an indicator of systemic disease. Risk factors for ED include cardiovascular disease, hypertension, diabetes mellitus (DM), tobacco use, hyperlipidemia, hypogonadism, lower urinary tract symptoms, metabolic syndrome, and depression. Addressing the modifiable risk factors frequently improves a patient's overall health and increases lifespan. The literature suggests that smoking cessation, treatment of hyperlipidemia, and increasing physical activity will improve erectile function in many patients. How the treatment of DM, depression, and hypogonadism impacts erectile function is less clear. Clinicians need to be aware that certain antihypertensive agents can adversely impact erectile function. The treatment of men with ED needs to address the underlying risk factors to ameliorate the disease process.

Abstract
BACKGROUND The association between subclinical cardiovascular disease and subsequent development of erectile dysfunction (ED) remains poorly described. HYPOTHESIS Among multiple subclinical atherosclerosis and vascular dysfunction measurements, coronary artery calcium (CAC) score best predicts ED. METHODS After excluding participants taking ED medications at baseline, we studied 1862 men age 45 to 84 years free of known cardiovascular disease from the Multi-Ethnic Study of Atherosclerosis (MESA) with comprehensive baseline subclinical vascular disease phenotyping and ED status assessed at MESA visit 5 (9.4 ± 0.5 years after baseline) using a standardized question on ED symptoms. Multivariable logistic regression was used to assess the associations between baseline measures of vascular disease (atherosclerosis domain: CAC, carotid intima-media thickness, carotid plaque, ankle-brachial index; vascular stiffness/function domain: aortic stiffness, carotid stiffness, brachial flow-mediated dilation) and ED symptoms at follow-up. RESULTS Mean baseline age was 59.5 ± 9 years, and 839 participants (45%) reported ED symptoms at follow-up. Compared with symptom-free individuals, participants with ED had higher baseline prevalence of CAC score >100 (36.4% vs 17.2%), carotid intima-media thickness Z score >75th percentile (35.3% vs 16.6%), carotid plaque score ≥2 (39% vs 21.1%), carotid distensibility <25th percentile (34.6% vs 17.1%), aortic distensibility <25th percentile (34.2% vs 18.7%), and brachial flow-mediated dilation <25th percentile (28.4% vs 21.3%); all P < 0.01. Only CAC >100 (odds ratio: 1.43, 95% confidence interval: 1.09-1.88) and carotid plaque score ≥2 (odds ratio: 1.33, 95% confidence interval: 1.02-1.73) were significantly associated with ED. CONCLUSIONS Subclinical vascular disease is common in men who later self-report ED. Early detection of subclinical atherosclerosis, particularly advanced CAC and carotid plaque, may provide opportunities for predicting the onset of subsequent vascular ED.

Abstract
PURPOSE OF REVIEW This narrative review discusses the associations of erectile dysfunction with coronary heart disease (CHD) morbidity and mortality, all-cause death and CHD risk factors. Treatment strategies for erectile dysfunction are also mentioned. RECENT FINDINGS Erectile dysfunction shares common pathways and risk factors with vascular diseases. Erectile dysfunction has been reported to independently predict CHD events, thus highlighting its role as a marker of early atherosclerosis. Erectile dysfunction prevalence may be followed by the presentation of CHD symptoms in 2-3 years, and a CHD event may occur in 3-5 years. Furthermore, erectile dysfunction has been associated with stroke, peripheral artery disease, diabetes and chronic kidney disease as well as with several CHD risk factors including hypertension, dyslipidaemia, smoking, obesity, metabolic syndrome, hyperuricaemia, arterial stiffness and obstructive sleep apnea syndrome. On the basis of these data, erectile dysfunction may be regarded as a part of polyvascular disease. SUMMARY Patients with erectile dysfunction are at an increased risk for CHD morbidity and/or mortality as well as for all-cause death. Clinicians should monitor patients with erectile dysfunction by assessing their vascular risk and preventing or adequately treating CHD risk factors. In this context, lifestyle interventions should be recommended in addition to drug treatment to attain better outcomes.

Abstract
INTRODUCTION Although clinical evidence supports an association between cardiovascular/metabolic diseases (CVMD) and erectile dysfunction (ED), scientific evidence for this link is incompletely elucidated. AIM This study aims to provide scientific evidence for the link between CVMD and ED. METHODS In this White Paper, the Basic Science Committee of the Sexual Medicine Society of North America assessed the current literature on basic scientific support for a mechanistic link between ED and CVMD, and deficiencies in this regard with a critical assessment of current preclinical models of disease. RESULTS A link exists between ED and CVMD on several grounds: the endothelium (endothelium-derived nitric oxide and oxidative stress imbalance); smooth muscle (SM) (SM abundance and altered molecular regulation of SM contractility); autonomic innervation (autonomic neuropathy and decreased neuronal-derived nitric oxide); hormones (impaired testosterone release and actions); and metabolics (hyperlipidemia, advanced glycation end product formation). CONCLUSION Basic science evidence supports the link between ED and CVMD. The Committee also highlighted gaps in knowledge and provided recommendations for guiding further scientific study defining this risk relationship. This endeavor serves to develop novel strategic directions for therapeutic interventions.

Abstract
BACKGROUND Statins are commonly prescribed for cardiovascular diseases which have been reported to share many contributory underlying mechanisms with erectile dysfunction (ED). However, the correlation between statin use and incident ED is uncertain. METHODS We conducted a population-based propensity-matched cohort study by identifying new statin users among male patients 40-79 years of age in the period 2000 to 2010. A statin nonuser control cohort matched for age, propensity score, and index year at a 3:1 ratio was selected for comparison. Cohorts were tracked for the occurrence of any type of incident ED according to the registry of ED diagnosis in the database. The association between statin use and the risk of ED was evaluated by Cox proportional hazard model and adjusted by age, PS, socioeconomic status, comorbidities, and medications. RESULTS Compared with nonusers, statin users had a significantly lower risk of incident ED (HR, 0.75; 95% CI, 0.63-0.90, p=0.002). Further analysis demonstrated that statin users in the group of middle-aged (40-49 years old) or high-potency statin treated (i.e., rosuvastatin, atorvastatin, and simvastatin) had lower HR for incident ED. Analysis in the patterns of cumulative statin exposure also showed that high-potency statins could decrease the HR for incident ED in dose- and duration-dependent manners. CONCLUSIONS Statin use was associated with a reduced risk of incident ED in the middle-aged men in Taiwan. The potency and the cumulative exposure of statin utilized played critical roles.

Abstract
The aim of this study was to evaluate the prevalence of erectile dysfunction (ED) in a cohort of Italian hypertensive men and the association with clinical and biochemical data. The study involved 270 consecutive hypertensive subjects aged 40-70 years evaluated in Italian Hypertension Centers of six hospitals from Liguria and Piedmont. ED was assessed through the self-administered questionnaire of the International Index of Erectile Function. Clinical history with ongoing drug treatment, various clinical parameters, biochemical data and evidence about the presence of subclinical target organ damage was collected. Twenty-seven subjects refused to answer the questionnaire (10%). Among the 243 remained subjects, 123 presented ED (50.6%). ED was highly related to age, systolic blood pressure, pulse pressure, smoking status, statin therapy and kidney function. The addition of a thiazide diuretic to an inhibitor of the renin-angiotensin system significantly increased the prevalence of ED. The prevalence of ED increased in relation with the number of hypotensive drug classes taken by the patients. ED was highly prevalent in this cohort of Italian hypertensive subjects and was associated with other cardiovascular risk factors, such as age, smoking status and kidney function. The role of ED as an early marker of cardiovascular disease is discussed.

Abstract
Cataract is the leading cause of visual impairment, other than uncorrected refractive errors, and the number one cause of preventable blindness worldwide. Common adverse events of statins include statin-related muscle toxicity, elevation of transaminases, diabetes, and possible association with cancer. Publications on the relationship of cataract to statins have reported inconsistent findings. A meta-analysis indicated a 19 % decrease in cataract among statin users. The pleiotropic effects of statins including effects on inflammation and oxidation may mediate a decrease in the rate of cataract formation. On the other hand, bidirectional effects of statins on oxidation and inhibition of appropriate lens epithelial cell development may promote cataractogenesis. Younger age and longer duration of statin therapy was associated with greater benefit while a benefit was not observed among older persons. A definitive way to settle the issue of the relationship of statins to cataract is to perform a randomized clinical trial or include cataract as an end point in epidemiologic studies. An increased risk of cataract may be balanced by the marked benefits of statins for those at high risk for cardiovascular events, while a decreased risk may help increase adherence to statin therapy.

Abstract
Statins are one of the most commonly prescribed drugs in clinical practice. They are usually well tolerated and effectively prevent cardiovascular events. Most adverse effects associated with statin therapy are muscle-related. The recent statement of the European Atherosclerosis Society (EAS) has focused on statin associated muscle symptoms (SAMS), and avoided the use of the term 'statin intolerance'. Although muscle syndromes are the most common adverse effects observed after statin therapy, excluding other side effects might underestimate the number of patients with statin intolerance, which might be observed in 10-15% of patients. In clinical practice, statin intolerance limits effective treatment of patients at risk of, or with, cardiovascular disease. Knowledge of the most common adverse effects of statin therapy that might cause statin intolerance and the clear definition of this phenomenon is crucial to effectively treat patients with lipid disorders. Therefore, the aim of this position paper was to suggest a unified definition of statin intolerance, and to complement the recent EAS statement on SAMS, where the pathophysiology, diagnosis and the management were comprehensively presented.
