Abstract
OBJECTIVES The present study aimed to investigate the relationship between male hormones and metabolic dysfunction-associated fatty liver disease (MAFLD) in males. METHODS Data from the Fangchenggang Area Male Health and Examination Survey (FAMHES) were used to analyze the male hormone levels between MAFLD patients and controls. Univariate and multivariate logistic regression analyses were performed to identify risk factors for MAFLD. Receiver operating characteristic curve analysis was used to assess the diagnostic performance of male hormones for MAFLD. RESULT A total of 1578 individuals were included, with 482 individuals (30.54%) of MAFLD, including 293 (18.57%) with mild disease and 189 (11.98%) with moderate-to-severe disease. The MAFLD patients were significantly older than those without MAFLD. The LH, FSH, and SHBG levels in the MAFLD patients were significantly greater than those in the control group. Age, FSH, LH, SHBG, and estradiol were all risk factors for MAFLD. Age, FSH, and LH were risk factors for moderate-to-severe MAFLD. FSH was an independent risk factor for MAFLD and moderate-to-severe MAFLD. FSH showed an excellent diagnostic value, with an AUC of 0.992 alone and 0.996 after adjusting age. CONCLUSIONS Our findings indicate that FSH may be a potential diagnostic and predictive biomarker for MAFLD.

Abstract
OBJECTIVES To investigate roles of brain carbon monoxide (CO), an endogenous gasotransmitter, in regulation of the rat micturition reflex. METHODS In urethane-anesthetized (0.8 g/kg, ip) male rats, evaluation of urodynamic parameters was started 1 h before intracerebroventricular administration of CORM-3 (CO donor) or ZnPP (non-selective inhibitor of heme oxygenase, a CO producing enzyme) and continued for 2 h after the administration. We also investigated effects of centrally pretreated SR95531 (GABAA receptor antagonist) or SCH50911 (GABAB receptor antagonist) on the CORM-3-induced response. RESULTS CORM-3 significantly prolonged intercontraction intervals (ICIs) without changing maximal voiding pressure (MVP), while ZnPP significantly shortened ICI and reduced single-voided volume and bladder capacity without affecting MVP, post-voided residual volume, or voiding efficiency. The ZnPP-induced ICI shortening was reversed by CORM-3. The CORM-3-induced ICI prolongation was significantly attenuated by centrally pretreated SR95531 or SCH50911, respectively. CONCLUSIONS Brain CO can suppress the rat micturition reflex through brain γ-aminobutyric acid (GABA) receptors.

Abstract
Background: Prostatic growth has been thought to be the systemic manifestation of some metabolic derangements in recent studies. Nonalcoholic fatty liver disease (NAFLD), a hepatic manifestation of the metabolic syndrome, might be closely linked with benign prostate hyperplasia and lower urinary tract symptoms (BPH/LUTS). Several studies have been conducted regarding NAFLD and BPH/LUTS association. However, the results are yet to reach a clear conclusion. We aimed to gather these studies' results to make a more robust analysis through a systematic review and meta-analysis. Methods: We systematically searched Pubmed-Medline, Cochrane Library, and Science Direct databases. We excluded all experimental studies, case reports, and reviews. Our search was restricted to the English language. We used standard mean difference for BPH/LUTS-related parameters. We identified the study qualities by the Newcastle-Ottawa Scale. We conducted a publication bias analysis. Results: A total of six studies involving 7089 participants fulfilled the inclusion criteria. Our meta-analysis revealed that patients with NAFLD have larger prostate volume [0.553 (0.303-0.802), P ˂ 0.001; Q = 97.41; P-value for heterogeneity = P < 0.0001; I2 = 94.86%]. However, the summary effect size of the other parameters of BPH/LUTS (prostate-specific antigen and international prostate symptom score) computed in our meta-analysis did not yield significant results. Conclusions: The prostate size was larger in patients with NAFLD, but the meta-analysis did not reach a significant result for LUTS among the studies. These results should be tested with well-designed studies, in particular, to clarify the association of LUTS with NAFLD.

Abstract
We aimed to assess the relationship between lifestyle-related variables, metabolic syndrome, and lower urinary tract symptoms (LUTS) in men ≥ 40 years. We also assessed the impact of these variables on quality of life. From 2014 to 2020, 5355 men who underwent health check-ups with I-PSS questionnaires at our institute were included in the analysis. The impact of LUTS on sleep disorders and moderate to severe degrees of stress were assessed. Multivariate analysis was performed to determine the variables associated with LUTS and prostate volume. Moderate and severe LUTS were present in 1317 (24.6%) and 211 (3.9%) men, respectively. Moderate and severe LUTS were significantly associated with the presence of sleep disorders and stress. On multivariable analysis, age, amount of life-long smoking, marital status, income, job, and decreased HDL-cholesterol were associated with the presence of moderate to severe LUTS. Although older age and the amount of life-long smoking was associated with both voiding and storage sub-score, socioeconomic status, including marital status and income were only associated with storage sub-score. In men ≥ 40 years, stable socioeconomic status, in addition to older age, and life-long smoking amount are associated with the presence of moderate to severe LUTS, which worsens sleep quality and stress level, by worsen storage sub-score.

Abstract
Background Non-alcoholic fatty liver disease (NAFLD) has been entitled as metabolic-dysfunction associated fatty liver disease (MAFLD). Therefore anthropometric indicators of adiposity may provide a non-invasive predictive and diagnostic tool for this disease. This study intended to validate and compare the MAFLD predictive and diagnostic capability of eight anthropometric indicators. Methods The study involved a population-based retrospective cross-sectional design. The Fangchenggang area male health and examination survey (FAMHES) was used to collect data of eight anthropometric indicators, involving body mass index (BMI), waist-to-height ratio (WHtR), waist-hip ratio (WHR), body adiposity index (BAI), cardiometabolic index (CMI), lipid accumulation product (LAP), visceral adiposity index (VAI), and abdominal volume index (AVI). Receiver operating characteristics (ROC) curves and the respective areas under the curves (AUCs) were utilized to compare the diagnostic capacity of each indicator for MAFLD and to determine the optimal cutoff points. Binary logistic regression analysis was applied to identify the odds ratios (OR) with 95% confidence intervals (95% CI) for all anthropometric indicators and MAFLD. The Spearman rank correlation coefficients of anthropometric indicators, sex hormones, and MAFLD were also calculated. Results All selected anthropometric indicators were significantly associated with MAFLD (P < 0.001), with an AUC above 0.79. LAP had the highest AUC [0.868 (95% CI, 0.853–0.883)], followed by WHtR [0.863 (95% CI, 0.848–0.879)] and AVI [0.859 (95% CI, 0.843–0.874)]. The cutoff values for WHtR, LAP and AVI were 0.49, 24.29, and 13.61, respectively. WHtR [OR 22.181 (95% CI, 16.216–30.340)] had the strongest association with MAFLD, regardless of potential confounders. Among all the anthropometric indicators, the strongest association was seen between LAP and sex hormones. Conclusion All anthropometric indicators were associated with MAFLD. WHtR was identified as the strongest predictor of MAFLD in young Chinese males, followed by LAP and AVI. The strongest association was found between LAP and sex hormones.

Abstract
Background To investigate the association between lower urinary tract symptoms suggestive of benign prostate hyperplasia (LUTS/BPH) and metabolic syndrome (MetS) in aging Chinese males. Methods A dataset that included 3,568 non-MetS cases and 1,020 MetS cases (after data cleansing) was downloaded from the China Health and Retirement Longitudinal Study (CHARLS). To balance the intergroup covariates, propensity score matching (PSM) was employed in the analyses. Univariate logistic regression and multivariate logistic regression were then performed to investigate the relationship between LUTS/BPH and MetS in aging Chinese males. Results Before PSM, multivariate logistic regression showed that participants with MetS had a 1.47 times higher risk of LUTS/BPH compared to non-MetS cases in the final model (P<0.001). It also revealed that participants with low high-density lipoprotein (HDL), abdominal adiposity, or high triglycerides had a higher probability of LUTS/BPH [odds ratio (OR) =1.56 for low HDL; OR =1.50 for abdominal adiposity; and OR =1.48 for high triglyceride, P<0.001], while participants with hyperglycemia or hypertension had identical odds of LUTS/BPH (P>0.05). After PSM, 1,000 pairs were successfully matched. It was also found that MetS cases had a 1.60 times higher risk of LUTS/BPH compared to non-MetS cases (P<0.001), and participants with low HDL, abdominal adiposity, high triglycerides, or hyperglycemia had a higher likelihood of LUTS/BPH than their counterparts (P<0.001). However, the probability of LUTS/BPH in hypertensive patients remained similar to that in non-hypertensive patients (P>0.05). Conclusions Aging Chinese males with MetS had a higher probability of LUTS/BPH. Also, patients with low HDL, abdominal obesity, high triglycerides, or hyperglycemia had an increased risk of LUTS/BPH; however, this was not the case for hypertensive patients.

Abstract
BACKGROUND Metabolic syndrome (MetS) is defined by at least three of the following five criteria: blood pressure ⩾130/85 mmHg, fasting blood glucose ⩾5.6 mmol/l, triglycerides concentration ⩾1.7 mmol/l, waist circumference ⩾102 cm (for men), and high-density lipoprotein cholesterol concentration <1.03 mmol/l (for men). MetS has been associated with worse lower urinary tract symptoms (LUTS) and higher International Prostate Symptom questionnaire scores. MATERIALS AND METHODS MEDLINE, Cochrane, ClinicalTrials.gov, and SCOPUS were critically appraised for all peer-reviewed manuscripts that suitably fulfilled our protocol's inclusion criteria established a priori. Meta-analytical and meta-regression calculations were performed in R using the Sidik-Jonkman and Hartung-Knapp random effects model and predefined covariates. RESULTS A total of 70 studies (n = 90,206) were included in qualitative synthesis. From these, 60 studies focused on MetS and LUTS: 44 reported positive correlations, 5 reported negative correlations, 11 reported no association, and 10 studies focused on MetS and total prostate volume (TPV). MetS positively correlated with moderate LUTS [odds ratio (OR) = 1.56, 95% confidence interval (CI) = 1.35-1.80], severe LUTS (OR = 2.35, 95% CI = 1.82-3.03), overactive bladder (OAB; OR = 3.2, 95% CI = 1.6-5.8), and nocturia severity (OR = 2.509, 95% CI = 1.571-4.007) at multivariate analysis. A total of 30 studies (n = 22,206) were included in meta-analysis; MetS was significantly associated with higher TPV (mean differences = 4.4450 ml, 95% CI = 2.0177-6.8723), but no significant predictive factors for effect sizes were discovered. CONCLUSION Our meta-analysis demonstrates a significant association between the aggravating effects of MetS, which commonly coexists with obesity and benign prostate enlargement.

Gene 2020; 763:145067. [PMID: 32827681 DOI: 10.1016/j.gene.2020.145067] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 08/03/2020] [Accepted: 08/17/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND rs2274911 (Pro91Ser, G > A) is a missense mutation located on the second exon of the GPRC6A gene. Increasing evidence revealed a significant association between the A allele of rs2274911 and male diseases, such as oligospermia, cryptorchidism, and prostate tumor. However, the function of rs2274911 in healthy males is unclear. SUBJECTS AND METHODS A total of 1742 healthy men were selected from the Fangchenggang Area Male Health and Examination Survey (FAMHES). The association between rs2274911 and phenotype was evaluated. The cell characteristics of rs2274911 mutation (mu), wild-type GPRC6A (WT), and RFP control in human embryonic kidney (293T) and human prostate cancer (PC3) cells were analyzed. RNA sequencing was performed on PC3 cells. RESULTS E2 and PSA serum levels increased with the accumulation of the A allele (E2: G vs. A, -0.029 [-0.050, -0.008], P < 0.01, P trend = 0.027; PSA: G vs. A, -0.040 [-0.079, 0.000], P < 0.05, P trend = 0.048). rs2274911 enhanced the proliferation and invasion ability of PC3 or 293T cells and activated the ERK pathway. The genes were identified as rs2274911 mu-affected genes through RNA sequential analysis of rs2274911 mu, GPRC6A WT, and RFP control of PC3 cells. Most of these genes were related to cancer development processes, cAMP, and the ERK cell signaling pathway. CONCLUSION This project represents that rs2274911 is associated with E2 and PSA serum levels in Southern Chinese men. Rs2274991 mutation promotes 293T and PC3 cell proliferation in vitro. These results suggest that rs2274911 is a functional variant of GPRC6A.

Abstract
Men ignore self-care, displaying low frequency in health services. Aging increases the prevalence of LUTS and BPE, impacting the quality of life. The objective is to understand how the advancement of age can be determinant for men's health in Natal, Brazil. Then, 503 men aged between 43 and 83 attended the Blue November Campaign of 2015. All subjects were submitted to anamnesis, clinical and laboratorial evaluation including measuring their blood pressure, waist circumference, glucose, total cholesterol, HDL-C, LDL-C, triglycerides and BMI was calculated. In addition, IPSS, PSA, IIEF-5 and DRE data were collected. The mean IPSS presented an increase with age, 43-59 years (6.28 ± 6.02) and 70-80 years or more (8.65 ± 5.80). PSA dosages increase with aging (adult group 1.63 ± 2.70), being more accentuated in the older group (4.66 ± 5.70), while the mean IIFE-5 showed a decrease with aging in 43-59 years (21.79 ± 4.67) and an important decrease at 70-80 years or more (16.24 ± 6.71). The number of DRE > 30 g showed significant growth in the older group. All presented statistical significance (p < .05) and were associated with aging. The Blue November Campaign creates an annual self-care opportunity for aging men as their health is gradually affected.

Drinking Frequency but not Years may be Associated with Lower Urinary Tract Symptoms: Result from a Large Cross-Sectional Survey in Chinese Men. Risk Manag Healthc Policy 2020; 13:633-642. [PMID: 32607031 PMCID: PMC7320899 DOI: 10.2147/rmhp.s238012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2019] [Accepted: 05/19/2020] [Indexed: 11/23/2022] Open
Abstract
Objective To evaluate the effect of the drinking frequency and years on lower urinary tract symptoms (LUTS) in a large Chinese male population. Methods The current data were obtained from a consecutive series of 3,229 men aged 18–79 who participated in a routine physical examination in Fangchenggang First People’s Hospital, Guangxi, China. During a face-to-face interview, the detailed demographic variables about alcohol consumption, potential confounding factors were collected. LUTS were assessed by International Prostate Symptom Score (IPSS) and defined as total LUTS, irritative (IRR) and obstructive (OBS) symptoms, respectively. Multivariate logistic regression analysis was used to evaluate the risk of total LUTS, IRR and OBS symptoms affected by alcohol consumption. Results The prevalence of moderate to severe LUTS was 8.3% and apparently increased with age (P<0.001). A significant distribution presented in age, alcohol consumption, BMI, cigarette smoking, education attainment and hypertension among different strata of LUTS severity (P<0.05). Men who drank 1–2 times per week were less likely to have OBS symptoms (OR=0.45, 95%CI=0.29–0.70) regardless of age (OR=0.52, 95%CI=0.33–0.82) or multivariate adjusted (OR=0.52, 95%CI=0.33–0.83). Nevertheless, we did not observe a significant negative or positive association presented between drinking years and the risk of total LUTS, OBS and IRR symptoms. Conclusion The current results imply that moderate drinking frequency may be protective against LUTS, and drinking years did not relate to worsening or improving LUTS.

Abstract
The prospective study is to investigate the associations between serum testosterone levels and LUTS among middle-aged men ≥40 years receiving health check-up. Lower urinary tract symptoms were evaluated by the self-administered International Prostate Symptom Score questionnaire. Serum prostate specific antigen and total testosterone level were checked in all subjects. A total of 1752 men were enrolled into the study. The mean age was 55.6 ± 9.7 years. All study subjects were stratified into low, medium and high testosterone levels by two cut-off, 3.0 and 4.11 ng/mL. We found that testosterone levels were significantly associated with metabolic syndrome and body fat components. Compared to those with low testosterone levels, subjects with high and medium testosterone had a significantly higher IPSS (5.84 ± 5.55 vs 6.71 ± 5.68 and 6.34 ± 5.66, p = 0.032) and storage score (2.76 ± 2.29 vs 3.20 ± 2.49 and 2.90 ± 2.49; p = 0.009), and a more moderate/severe LUTS (IPSS ≧ 8) (26.5% vs 35.7% and 29.9%; p = 0.002). Multivariate analyses showed that high vs low testosterone levels (OR, 1.76; 95% CI, 1.26–2.45) and prostate volume ≧25 vs <25 mL (OR, 1.38; 95% CI, 1.04–1.82) significantly associated with the presence of moderate/severe LUTS. Pearson correlation analyses showed significantly positive correlations between testosterone level and IPSS in whole study sample (Pearson correlation coefficient, 0.066; p < 0.01) and in the subgroup of moderate/severe LUTS (Pearson correlation coefficient, 0.038; p < 0.05). In conclusion, high testosterone and prostate volume adversely impacted LUTS in our target population.

Central obesity indicating a higher prevalence of lower urinary tract symptoms: A case-control matching analysis from a Chinese cross-sectional study in males. Low Urin Tract Symptoms 2018; 11:O135-O140. [PMID: 29971968 DOI: 10.1111/luts.12231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2018] [Revised: 05/04/2018] [Accepted: 06/04/2018] [Indexed: 11/26/2022]
Abstract
OBJECTIVE The aim of this study was to explore the association between central obesity and lower urinary tract symptoms (LUTS) among men in southern China, and test the hypothesis that central obesity measured by the waist-to-hip ratio (WHR) is a predictor of the severity of LUTS. METHODS In all, 4303 men from the Fangchenggang Area Male Healthy and Examination Survey (FAMHES) were included in this study. LUTS were assessed by the International Prostate Symptom Score (IPSS), whereas central obesity was evaluated by the WHR. The association between WHR and LUTS was tested using logistic and Cox regression analyses. RESULTS After screening, 2917 participants were in the study. Univariate analysis indicated significant differences in WHR in the presence of LUTS (P = .012). After stratification by age, logistic regression indicated that LUTS were more frequent in 60-year-old men with a higher WHR (odds ratio [OR] 2.89, 95% confidence interval [CI] 1.21-6.89) compared with participants <40 years old. Cox regression analysis after pairing of 252 LUTS cases and 252 control subjects from the 2917 eligible participants according to age (±5 years), indicated that central obesity (WHR ≥0.9) may be significantly associated with moderate or severe LUTS (OR 1.95, 95% CI 1.16-3.26). The associations between central obesity and straining (OR 2.44, 95% CI 1.40-4.24) and weak stream (OR 2.37, 95% CI 1.27-4.45) were significant after multivariate adjustment. CONCLUSIONS Males with central obesity are at increased risk of LUTS, and increased WHR is associated with worsened straining and weak stream. Further investigations are needed to confirm these associations.

Abstract
Lower urinary tract function is modulated by neural, vascular and urethral and bladder structural elements. The pathophysiological mechanisms of lower urinary tract symptoms (LUTS) encompass prostate enlargement, alterations in urethra histological structure bladder fibrosis and alterations in pelvic neuronal and vascular networks, The complex pathophysiological relationship between testosterone (T) deficiency (TD) and the constellations LUTS, and metabolic dysfunction manifested in the metabolic syndrome (Met S) remains poorly understood. TD has emerged as one the potential targets by which Met S may contribute to the onset and development as well as worsening of LUTS. Because it has been recognized that treatment of men with Met S with T therapy ameliorates Met S components, it is postulated that T therapy may represent a therapeutic target in improving LUTS. Furthermore, the effect of TD on the prostate remains unclear, and often debatable. It is believed that T exclusively promotes prostate growth, however recent evidence has strongly contradicted this belief. The true relationship between benign prostatic hyperplasia, TD, and LUTS remains elusive and further research will be required to clarify the role of T in both benign prostatic hypertrophy (BPH) and LUTS as a whole. Although there is conflicting evidence about the benefits of T therapy in men with BPH and LUTS, the current body of literature supports the safety of using this therapy in men with enlarged prostate. As the population afflicted with obesity epidemic continues to age, the number of men suffering from Met S and LUTS together is expected to increase.

Abstract
There has been no previous population-based study reporting the prevalence and risk factors of male lower urinary tract symptoms (LUTS) among men in mainland China. This cross-sectional study was conducted from 2013 to 2014 in three representative provinces of China: Guangdong, Hubei and Jiangsu. 3250 individuals participated in the interviews, which involved a questionnaire covering sociodemographic characteristics, lifestyle, dietary patterns and the International Prostate Symptom Score (IPSS). Blood was collected for lipids, glucose, insulin and reproductive hormone tests. The incidences of LUTS and its obstructive and irritative symptoms were calculated. Risk factors for LUTS were identified using multivariable logistic regression analysis. The prevalence of moderate to severe LUTS and its obstructive and irritative symptoms was 14.3%, 13.1% and 16.1%, respectively, and increased with age. The prevalence in Guangdong was much lower than that in Hubei and Jiangsu in different ages. Increased fasting plasma glucose and decreased HDL-C levels were associated with an increased risk of moderate to severe LUTS (OR = 1.30, 95% CI: 1.02–1.65 and OR = 2.06, 95% CI: 1.08–3.94, respectively). Free testosterone < 0.22 ng/ml decreased the risk of moderate to severe LUTS and obstructive and irritative symptoms by about 20–30%. An inadequate daily intake of vegetables, fruit and water significantly increased the risk of LUTS by 1.3–to 2.0 times. In conclusion, the prevalence of LUTS in Chinese men is high and increases with age. Dietary patterns may be critical for the development of LUTS. Thus, dietary modifications could be a useful strategy for preventing the development of LUTS.

Abstract
OBJECTIVES To estimate the frequency of metabolic syndrome (MetS) in a daily urology practice and to determine its association with lower urinary tract symptoms (LUTS) and erectile dysfunction (ED). MATERIAL AND METHODS A retrospective study was conducted. Data from all male patients aged ≥40 years who attended our outpatient urology clinic from 2010 to 2011 was collected. Prevalence of MetS was determined, and LUTS and ED were assessed. A logistic model was used to determine possible associations, controlling for confounders and interaction factors. RESULTS A total of 616 patients were included. MetS was observed in 43.8% (95% CI 39.6-48.3). The bivariate model showed an association between MetS and LUTS (p<0.01), but not between MetS and ED. The logistic model showed an association between MetS and the International Prostate Symptom Score (IPSS), while controlling for other variables. Patients exhibiting moderate LUTS had a greater risk for MetS than patients with mild LUTS (OR 1.83, 95% CI 1.14-2.94). After analyzing for individual components of MetS, positive associations were found between diabetes and severe LUTS (OR 1.3, 95% CI 1.24-7.1), and between diabetes and ED (OR 2.57, 95% CI 1.12-5.8). CONCLUSION This study was able to confirm an association between MetS and LUTS, but not for ED. Specific components such as diabetes were associated to both. Geographical differences previously reported in the literature might account for these findings. Given that MetS is frequent among urological patients, it is advisable that urologists actively screen for it.

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
PURPOSE OF REVIEW The metabolic syndrome (MetS) is an ever growing pandemic consisting of a constellation of abnormalities. Many hypotheses have been put forth to establish a link between this syndrome and voiding dysfunction. We created a layout of the possible, probable, and proven relationships connecting the MetS with voiding dysfunction in men. RECENT FINDINGS There has been growing interest in the relationship linking MetS and voiding dysfunction, with or without benign prostatic hyperplasia, during the past several years. Different mechanisms have been proposed to establish the connection. SUMMARY A clear-cut association between MetS and voiding dysfunction is not clearly defined; rather, voiding dysfunction occurring in men with MetS has been shown to be related to numerous pathologies. MetS is a complex disease that includes numerous pathophysiological aspects that may contribute to the causation and advancement of voiding dysfunction. In light of this association, future research is needed to better define this relationship to enable therapy targeted against MetS in patients with voiding dysfunction.

Abstract
Metabolic syndrome (MS) is a highly prevalent disease related to the risk of cardiovascular disease and diabetes. A large body of evidence has suggested a link between MS and the components of MS with lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) complex. The pathogenesis of MS is complex and not fully understood. Furthermore, recent results from epidemiological studies, including multiple Asian reports, have not been consistent. The risk of BPH is lower in Asian men compared with white men and the prevalence of MS varies by race and ethnicity. An elevated risk of Type 2 diabetes mellitus, hypertension, and dyslipidaemia is closely related to MS and is observed in Asian men even if their body mass index is low. However, the role of race and ethnic disparity in the link between MS and LUTS secondary to BPH is not elucidated. It has been suggested that the pathogenesis of LUTS is multifactorial rather than developing from BPH, which is the traditional concept. Lifestyle and genetic factors may substantially modify the risk of MS and LUTS/BPH. This comprehensive literature review summarises the scientific evidence of the racial/ethnic disparity regarding the association between MS and LUTS/BPH in order to improve current understanding of this controversial issue.

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
Background The effect of alcohol consumption on prostate health and reproductive hormone profiles has long been investigated and currently, no consensus has been reached. Additionally, large studies focusing on this topic are relatively rare in China. Purpose To investigate the association of alcohol consumption with prostate measurements and reproductive hormone profiles in Chinese population; and to examine the relationship between hormone levels and prostate measurements. Methods This cross-sectional study included 4535 men from four representative provinces of China. Demographic details, family history of prostate disease, tobacco and alcohol consumption, as well as International Prostate Symptom Score (I-PSS) were collected through a questionnaire. Total prostate specific antingen (total PSA), free PSA, free PSA/total PSA ratio (f/tPSA), and reproductive hormones were measured in serum. Multi-variable regression models were used to test for association of alcohol consumption with markers of prostate health, used to test for association of alcohol consumption with reproductive hormones, and reproductive hormones with markers of prostate health. Results Alcohol consumption had no obvious impact on total PSA concentration and I-PSS. Current drinkers had lower level of free PSA (β = -0.11, p = 0.02) and f/tPSA (β = -0.03, p = 0.005), former drinkers also had lower level of free PSA (β = -0.19, p = 0.02) when compared with never drinkers. Lower Luteinizing hormone (LH) (β = -1.05, p = 0.01), sex hormone-binding globulin (SHBG) (β = -4.71, p = 0.01) and higher estradiol (β = 7.81, p = 0.01) was found in current drinkers than never drinkers, whereas higher LH (β = 1.04, p = 0.04) and free testosterone (FT) (β = 0.03, p = 0.02) was detected in former drinkers than never drinkers. Furthermore, LH was positively associated with f/tPSA (β = 0.002, p = 0.006), SHBG was also positively related with free PSA (β = 0.003, p = 0.003) and f/tPSA (β = 0.0004, p = 0.01). Both total testosterone (TT) and FT were inversely related with I-PSS (OR = 0.97, 95% CI, 0.95–0.98; OR = 0.23, 95% CI, 0.11–0.45, respectively). Conclusions Alcohol consumption could affect serum free PSA concentration and also f/tPSA ratio, and also acts as an endocrine disruptor on the male reproductive hormone profiles. LH and SHBG were positively related with fPSA and f/tPSA, and higher level of TT and FT may be helpful for improving participants' subjective symptoms.

Abstract
PURPOSE To investigate the impact of metabolic syndrome (MetS) on benign prostatic hyperplasia (BPH), focusing on MetS and its relationship with prostate volume and prostate-specific antigen (PSA) in Chinese patients by performing a meta-analysis. METHODS We systematically searched the PubMed, Embase, China National Knowledge Infrastructure, Wanfang, and VIP databases from inception to November 2014. All studies investigating the impact of MetS on prostate volume and PSA among BPH patients were included. Pooled mean difference (WMD) and 95% confidence interval (CI) were used to analyze the difference between patients with MetS and those without MetS. RESULTS Sixteen studies enrolled 1895 BPH patients, of whom 2224 had MetS. Compared with those without MetS, BHP patients with MetS had significantly higher total prostate volume (WMD 10.15 ml; 95% CI 7.37-12.93) and serum PSA level (WMD 0.53 ng/ml; 95% CI 0.17-0.88), respectively. In addition, annual prostate growth rate in patients with MetS was higher (WMD 0.49 ml/year; 95% CI 0.24-0.73) than in those without MetS. CONCLUSIONS This meta-analysis supports that the presence of MetS increases total prostate volume and annual prostate growth rate in Chinese BPH patients. Future studies are needed to explain the detailed underlying mechanisms.

Abstract
The aim of the study was to test the hypothesis that the metabolic syndrome (MS) is linked to lower urinary tract symptoms (LUTS) in Korean men. This was a longitudinal study that used data collected from 328 men aged 50–89 years who were randomly selected among 1,520 participants in 2004. We collected information from 224 (68.3%) men among the original responders on the biological, medical, psychological, social, lifestyle, and economic factors in 2007. The prevalence of the MS was 187/328 (57.0%) in 2004 and 125/224 (55.8%) in 2007 among men, respectively. There was no significantly greater increase in the IPSS in men with the MS than in men without the MS over a 3-year period of time (2.0 ± 9.37 versus 3.0 ± 8.44, p = 0.402, resp.). In the multivariate logistic regression analysis with control for age and life style factors, the risk factors for moderate/severe LUTS were age and erectile dysfunction (p < 0.05). However, the presence of the MS did not increase the risk of moderate/severe LUTS (OR = 1.09, 95% CI 0.63–1.89, p = 0.748). Our cross-sectional and longitudinal risk factor analyses do not support the hypothesis that the MS is linked to LUTS in Korean men.

Abstract
BACKGROUND Metabolic Syndrome (MS) has become a global public health and has been suggested to be a risk factor for Lower Urinary Tract Symptoms (LUTS). Studies evaluating the association between the rate of the MS and LUTS often showed controversial results. OBJECTIVES The purpose of this study was to reveal the relevance of MS and its components on the frequency and severity of the LUTS that were seen with Benign Prostate Hyperplasia (BPH) in Turkish men or not. PATIENTS AND METHODS In this study, 237 patients referred to urology policlinic with BPH were retrospectively scanned between April 2009 and April 2013. Patients with normal digital rectal examination and the Prostate Specific Antigen (PSA) level of ≤ 4 ng/mL were evaluated using the International Prostate Symptom Score (IPSS) and all the data of the patients' body, including Body Mass Index (BMI), lipid parameters, preprandial blood glucose, and waist circumference. Seventy-four patients (31.3%) with mild IPSS (0-7) was group 1; 97 patients (40.9%) with moderate IPSS (8 - 19) group 2 and 66 patients (27.8%) with severe IPSS (20-35) were defined as group 3. group 4 consisted of 117 healthy controls. Three groups and controls were compared about MS and its components. The diagnosis criteria of The Society of Endocrinology and Metabolism of Turkey were used in MS diagnosis. Also, BMI, lipid parameters, preprandial blood glucose, waist circumference, and blood pressure were used as MS parameters. RESULTS The average age of patients in group 1 was 69.8 ± 7.2; in group 2, 69.1 ± 7.4; 68.3 ± 7.1 in group 3 and 70.2 ± 7.2 in the control group. Metabolic syndrome was determined at 37 patients (50%) in group 1, 45 patients (46.5%) in group 2, 32 patients (48%) in group 3 and 52 patients (44.4%) in controls and no statistically significant correlation was detected between LUTS and MS in BPH (P = 0.113). In the comparison of the four groups in the point of MS parameters, no significant correlation was detected in the levels of total cholesterol (P = 0.337), fasting glucose (P = 0.291), BMI (P = 0.452), Low Density Lipoprotein (LDL, P = 0.069) and triglyceride (P = 0.307). CONCLUSIONS In our study, the evidence is not enough to support the hypothesis of the relevance between MS and LUTS. Wide-ranging, prospective and multicentric studies are needed to research the relevance between MS and LUTS in BPH.

Abstract
BACKGROUND Elevated serum ferritin levels have been reported to contribute to metabolic syndrome (MetS). We examined the association of serum ferritin levels with the development of MetS in a representative sample of Chinese male adult population. METHOD The data came from the 2009-2013 Fangchenggang Area Males Health and Examination Survey (FAMHES). We combined a cross-sectional study of 2417 males and a longitudinal study of 857 males who participated in the FAMHES. RESULT The serum ferritin level of MetS was higher than that of nonMetS (median and percentiles 25-75: 447.4 (294.1-612.4) vs. 302.4 (215.0-435.8) ng/ml, p < 0.01). A positive correlation between ferritin concentrations and blood pressure (Systolic BP: R = 0.110, Diastolic BP: R = 0.158), waist circumference (R = 0.333), fasting glucose (R = 0.089), triglyceride (R = 0.315) and low high-density lipoprotein cholesterol (R = 0.130) was significant (all p < 0.001). Compared with the level of ferritin in the group with no MetS component, the group with all five MetS components had a higher ferritin level (554.7 (340.1-606.4) vs. 274.2 (198.2-384.4) ng/ml). The odd radio (OR) was higher for MetS in the highest ferritin quartile (OR = 2.29, 95% CI = 1.47-3.54) compared with the lowest ferritin quartile after adjustment for multi-factors. After 4-year follow up, 79 subjects newly diagnosed with MetS in 857 cohort male participants in 2013. Compared with the lowest ferritin quartile, the RR of the highest ferritin quartile was 2.55 (95% CI = 1.30-5.00) after multiple adjustments (p < 0.01). CONCLUSION Our findings confirm that the serum ferritin level is associated with the independent components of MetS, and elevated ferritin level is an independent risk factor for MetS development in the Chinese male population during the 4-year follow-up period.

Abstract
A significant amount of epidemiological evidences have underlined an emerging link between metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement a (BPE). We aimed to assess the connections between LUTS and MetS with its components. Meta-analysis were conducted to determine the mean differences (MD) and confidence intervals of IPSS total score, IPSS-voiding, IPSS-storage and prostate volume (PV) in patients with or without MetS. Ln(odds-ratio) were calculated to estimate the risk of having moderate-to-severe LUTS (IPSS ≥ 8). Nineteen studies were identified as eligible for this systematic review, with a total of 18,476 participants, including 5554 (30.06%) with and 12,922 (69.94%) without MetS. Pooled analysis did not demonstrate significant MD of IPSS, IPSS-voiding and IPSS-storage in men with or without MetS but PV was significantly different (MD = 2.18; p = 0.03). Presence of MetS was not significantly associated with moderate-to-severe LUTS (odds ratio = 1.13; p = 0.53) and only altered serum triglycerides and diabetes were associated with this risk. The association between MetS and LUTS/BPE remain unclear and further observational studies in a population with metabolic disorders should be conducted in order to address it's potential role in determining LUTS/BPE.

Abstract
OBJECTIVE This study aimed to investigate the association between auricular reflective points and the status of lower urinary tract symptoms (LUTS) among Chinese aging males. METHODS A total of 113 male participants, with 69 having LUTS (LUTS+ve) and 44 having no LUTS (LUTS-ve), were recruited for this case-control study. Ear diagnosis was conducted in three ways: inspection, electrical skin resistance measurement, and tenderness testing. RESULTS Quality of life was lower among the LUTS+ve cases than among the LUTS-ve cases. The tenderness and electrical conductivity of a number of auricular points, including the "angle of superior concha", the "urinary bladder", the "ureter", the "kidney", the "urethra", and the "internal genitals" were associated with LUTS in the Chinese aging males. In terms of electrical conductivity, the "angle of superior concha" on both ears exhibited the highest sensitivity among the other auricular points under testing. This auricular point also demonstrated considerable sensitivity, specificity, and positive/negative predictive values for both ears during the tenderness testing. CONCLUSIONS Auricular diagnosis has a pre-diagnostic value and could be considered as a screening method for the aging population with relatively high LUTS risk.

Abstract
Recently, clinical and epidemiologic data indicating the involvement of metabolic syndrome (MetS) in the pathogenesis and progression of lower urinary tract symptom (LUTS)/benign prostatic hyperplasia (BPH) are reported. This review evaluates the reports on the influence of MetS in the development and progression of LUTS/BPH, and discusses possible clinical implications for the management and treatment of this disease. Recent studies on the epidemiological relationship between MetS and LUTS hypothesize that MetS may be associated with an overactivity of the autonomic nervous system for which hyperinsulinemia, a key element of the MetS, might be responsible. An alternative explanation is that LUTS are associated with chronic ischemia of pelvis resulting from atherosclerotic changes in blood vessels, which leads the production of reactive oxygen species, which can damage the bladder detrusor. Control of autonomic nervous system overactivity and control of chronic bladder ischemia have potential as new targets for LUTS treatment. Studies suggest an association of MetS with LUTS/BPH, although further research is needed to understand how MetS influences LUTS/BPH. MetS should be considered a new domain in basic and clinical research in patients with LUTS/BPH and as a target for treatment.

Abstract
OBJECTIVE The aim of the present study was to evaluate the impact of metabolic syndrome (MetS) on benign prostatic hyperplasia (BPH) in elderly Chinese men. METHODS A total of 401 elderly BPH patients were divided into the without or with MetS group to assess the associations of MetS and components of MetS with BPH. Urologic evaluation included prostate volume, International Prostate Symptom Score, serum prostate-specific antigen, duration of concomitant lower urinary tract symptoms (LUTS) and maximum flow rate. RESULTS Body mass index (BMI), waist circumference, fasting glucose, glycosylated hemoglobin, triglyceride, fasting insulin (FINS), insulin resistance assessed by homeostasis model assessment (HOMA-IR) were greater and high-density lipoprotein cholesterol (HDL-C) was lower in BPH patients with MetS than in those without MetS. The patients with MetS showed a significantly larger prostate volume (p = 0.000) and longer duration of LUTS (p = 0.006) than those without MetS. Prostate volume was positively correlated with BMI (p = 0.000), FINS (p = 0.001), HOMA-IR (p = 0.003) and inversely correlated with HDL-C (p = 0.000). Multiple linear regression analysis showed that prostate volume was significantly correlated with HOMA-IR (p = 0.015). CONCLUSIONS Our results suggest that MetS, BMI, low HDL-C level, increased serum insulin and especially insulin resistance are considered risk factors for prostate enlargement in elderly Chinese men.

Is metabolic syndrome truly a risk factor for male lower urinary tract symptoms or just an epiphenomenon? Adv Urol 2014; 2014:203854. [PMID: 24587797 PMCID: PMC3920975 DOI: 10.1155/2014/203854] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2013] [Revised: 12/06/2013] [Accepted: 12/07/2013] [Indexed: 11/18/2022] Open
Abstract
To define whether the association of male lower urinary tract symptoms (LUTS) and metabolic syndrome (MS) is real or simply an epiphenomenon, 490 male adults (mean age 58 ± 9 years) underwent International Prostate Symptom Score (IPSS), physical and prostate digital examinations, blood analysis, and urinary tract transabdominal ultrasound with prostate volume measurement. Mild, moderate, and severe LUTS were found in 350 (71.4%), 116 (23.7%), and 24 (4.9%) patients, respectively. MS was present in 198 (40.4%) patients, representing 37.4% (131 of 350) of those with mild LUTS, 46.5% (54 of 116) of those with moderate, and 54.1% (13 of 24) of those with severe. The odds ratio of MS having moderate or severe LUTS was 2.1. MS was more common in older age, higher body mass index, and larger prostate size. Moderate and severe LUTS were more frequent in older age, lower levels of high density cholesterol, and higher blood pressure. Older age and body mass index had significant relative risk for lower urinary tract symptoms and only age remained independent factor for LUTS on multivariate analysis. Our results suggest that the association of male LUTS, prostate volume, and MS might be coincidental and related to older age.

Abstract
Benign prostatic hyperplasia (BPH) represents a pattern of non-malignant growth of prostatic fibromuscular stroma. Metabolic disturbances such us pre-diabetes and metabolic syndrome may have a role in BPH pathophysiology. A potential explanation for the above relationship involves the insulin-like growth factor (IGF) axis as well as IGF binding proteins, (IGFBPs) of which the most abundant form is IGFBP-3. Therefore, the aim of the present study was to investigate the association between intra-prostatic levels of IGF-1, IGF-2 as well as to evaluate the role of locally expressed IGFBP-3 in BPH development in pre-diabetes. A total of 49 patients admitted to the Urology department of a tertiary urban Greek hospital, for transurethral prostate resection, or prostatectomy and with pre-diabetes [impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) or both] were finally included. The majority of the sample consisted of subjects with IGT (51.0%), followed by IFG and IGT (32.7%) and isolated IFG (16.3%). For all participants a clinical examination was performed and blood samples were collected. In addition, total prostate (TP) volume or transitional zone (TZ) volume were estimated by transrectal ultrasonography. The results of the multivariate analysis regarding TP volume showed that higher PSA (p<0.001), larger waist circumference (p=0.007) and higher IGFBP-3 expression levels (p<0.001) independently predicted higher TP volume. The results regarding the volume of the TZ showed that higher PSA (p<0.001), larger waist circumference (p<0.001) and higher IGFBP-3 expression levels (p=0.024) were independently associated with higher TZ volume. Our findings show that intra-prostatic levels of IGFBP-3, PSA and waist circumference, but not overall obesity, are positively associated with prostate volume. IGFBP-3 seems to be a multifunctional protein, which can potentiate or inhibit IGF activity.

Abstract
Objective To establish a possible association between obesity, measured by waist circumference (WC) and body mass index (BMI), and voiding and sexual functions in a random cohort of Saudi men. Materials and methods An outpatient men’s health clinic was set up at King Abdulaziz University Hospital in Jeddah, Saudi Arabia and men were invited to discuss their sexual and urinary functions. The data collected included age, WC, weight, height, blood pressure, history of diabetes, hypertension, and smoking. The International Prostate Symptom Score (IPSS) and the International Inventory of Erectile Function (IIEF-5) questionnaire were used to assess urinary tract symptoms and sexual function, respectively. Serum testosterone, prostate-specific antigen and cholesterol levels were measured and documented. Data were analyzed using the Statistical Package for the Social Sciences. Results We recruited 113 participants. The mean WC and BMI of the men were 104 ± 14.599 cm and 29.706 kg/m2, respectively. Thirty-seven men (32.7%) had an IPSS ≥ 8 points. Sexual disorders were reported in 19 men; 16 men had erectile dysfunction, while three had premature ejaculation. Of the whole cohort, 37 men were diabetic, of which 15 (40.5%) had an IPSS ≥ 8 and 13 (35%) were either overweight or obese. Conclusion Increased WC and BMI were associated with diabetes mellitus and large percentages of voiding and sexual disorders.

Abstract
OBJECTIVE To investigate the impact of metabolic syndrome on lower urinary tract symptoms in a sample of middle-aged men receiving a health checkup. METHODS Subjects aged 45 years or older who voluntarily underwent a medical checkup were enrolled. Participant demographics and health history were collected by a self-administered questionnaire. All participants were stratified into 2 groups by the presence of metabolic syndrome, as defined according to the updated National Cholesterol Education Program's Adult Treatment Panel III. Prostate volume and prostate-specific antigen levels were used for subgroup analysis. RESULTS During January through December of 2010, 708 subjects with a mean age of 55.6 ± 9.72 years were enrolled into the study. Compared to the nonmetabolic syndrome group, the metabolic syndrome group had lower total international prostatic symptoms score (7.89 ± 6.63 vs 6.85 ± 6.52, P = .05) and lower severity of weak urinary stream (1.24 ± 1.60 vs 0.95 ± 1.50, P = .021). In the higher prostate volume group (prostate volume ≥ 30 mL), total international prostatic symptoms score, storage score, and urinary frequency, urgency and incomplete emptying were lower in men vs those without metabolic syndrome (all P < .05). The negative association between voiding score, severity of lower urinary tract symptoms, and metabolic syndrome became particularly pronounced as the number of metabolic syndrome factors increased (P for trend < .01). CONCLUSION We confirmed that metabolic syndrome had favorable effects on lower urinary tract symptoms, including voiding and storage symptoms in healthy middle-aged men. This beneficial effect was most significant in men with enlarged prostate and/or high prostate specific antigen levels.

Abstract
PURPOSE To investigate any associations between lower urinary tract symptoms (LUTS)/benign prostate hyperplasia (BPH) and metabolic syndrome (MetS). MATERIALS AND METHODS In all, 1,224 male police officers in their 50s who had participated in health examinations were included. LUTS/BPH was assessed by serum prostate-specific antigen, International Prostate Symptom Score (IPSS), transrectal ultrasonography, maximum urinary flow rate (Q max), and postvoid residual urine volume (PVR). In addition, testosterone was also examined. The MetS was defined using NCEP-ATP III guidelines. We used the multiple linear regression test and logistic regression analyses to examine the relationships. RESULTS MetS was diagnosed in 29.0% of participants. There was no significant difference in the percentage of cases of BPH (IPSS >7, Q max <15 ml/sec, and prostate gland volume ≥ 20 ml) (14.2% in the non-MetS group vs. 17.2 in the MetS group; p value=0.178). The total IPSS score and the Q max were not significantly different. The prostate volume and PVR were significantly greater in the subjects with MetS. After adjusting for age and testosterone, the presence of MetS was not associated with BPH (multivariate odds ratio, 1.122; 95% confidence interval, 0.593~2.120). Additionally, MetS was not related to IPSS (Beta, -0.189; p value=0.819), prostate volume (Beta, 0.815; p value=0.285), Q max (Beta, -0.827; p value=0.393), or PVR (Beta, 0.506; p value=0.837). CONCLUSIONS According to our results, the MetS was not clearly correlated with LUTS/BPH in Korean men in their 50s.

Abstract
OBJECTIVE To determine which measurement variable, waist circumference (WC), body mass index (BMI), or waist-to-hip ratio (WHR) is most closely related to the prostate volume (PV), prostate-specific antigen (PSA), and lower urinary tract symptoms (LUTS). METHODS Between January 2010 and September 2011, 1632 consecutive ostensibly healthy Korean men aged 40-69 years who visited our clinic for a prostate checkup were enrolled into the study. Exclusion criteria included pyuria, history of lower urinary tract disorder influencing urination, and a high PSA level of >3.0 ng/mL. All men underwent a detailed clinical evaluation using the International Prostate Symptom Score (I-PSS) questionnaire. Anthropometric measurements were determined. Serum PSA, urinalysis, and transrectal ultrasound were also performed. RESULTS Data from 1601 men were analyzed. The mean age was 51.6 years, WC 83.7 cm, BMI 24.8 kg/m(2), PV 24.6 mL, and the mean PSA level was 1.07 ng/mL. Using multivariate analysis, PV most positively associated with WC (P < .001), while PSA level had negatively associated with BMI (P = .036) and no significant association with WC or WHR was noted. There was no significant relationship between various obesity indexes and I-PSS. CONCLUSION Our data showed that PV positively associated with central obesity, as represented by WC. In contrast, serum PSA negatively associated with BMI, which represented overall obesity (ie, hemodilution). Our data also suggested that obesity is not associated with lower urinary tract symptoms in Korean men.

Abstract
CONTEXT Metabolic syndrome (MetS), a cluster of several metabolic abnormalities with a high socioeconomic cost, is considered a worldwide epidemic. Recent epidemiologic and clinical data suggest that MetS is involved in the pathogenesis and progression of prostatic diseases such as benign prostatic hyperplasia (BPH) and prostate cancer (PCa). OBJECTIVE This review evaluates the available evidence of the role of MetS in BPH and PCa development and progression and discusses possible clinical implications for the management, prevention, and treatment of these diseases. EVIDENCE ACQUISITION A National Center for Biotechnology Information (NCBI) PubMed search for relevant articles published between 1995 and September 2011 was performed by combining the following Patient population, Intervention, Comparison, Outcome (PICO) terms: male, metabolic syndrome, prostate, benign prostatic hyperplasia, prostate cancer, prevention, diagnosis, treatment, and prognosis. Additional references were obtained from the reference list of full-text manuscripts. EVIDENCE SYNTHESIS MetS is a complex, highly prevalent disorder and a worldwide epidemic. Central obesity, insulin resistance, dyslipidemia, and hypertension are the main components of MetS. Notwithstanding all the attempts made to correctly define MetS, a major problem related to most definitions remains the applicability to different populations and ethnic groups. Although there is growing evidence of the association of MetS with the initiation and clinical progression of BPH and PCa, molecular mechanisms and effects on treatment efficacy remain unclear. Further research is required to better understand the role of MetS in BPH and PCa. CONCLUSIONS Data from the peer-reviewed literature suggest an association of MetS with BPH and PCa, although the evidence for a causal relationship remains missing. MetS should be considered a new domain in basic and clinical research in patients with prostatic disorders.
