Abstract
BACKGROUND Diabetes has been associated with an increased risk of benign prostatic hyperplasia (BPH). However, the role of antidiabetic drugs as a BPH risk factor is unclear. The objective of our study was to examine the risk of BPH by antidiabetic drug use and glycemic control in a large population-based cohort of Finnish men. METHODS A total of 74,754 men in the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC) free of BPH at baseline in 1996-1999 were linked to the national medication reimbursement database for information on physician-prescribed antidiabetic drug purchases. Information on recorded BPH procedures and diagnoses was obtained from the National Care Register for Health Care, and for a subgroup of 17,739 men, information on blood glucose levels (BGLs) from the Fimlab Laboratories database. Cox regression with antidiabetic drug use and BGL as time-dependent variables was used to analyze the risks for starting BPH medication, recorded BPH diagnosis, and undergoing BPH surgery. The analysis was adjusted for age, use of statins, antihypertensive medication, and nonsteroidal anti-inflammatory drugs. RESULTS Of the subjects, 14,012 men (18.7%) used antidiabetic medication. Of the subgroup with fasting blood glucose data available, 7487 (42.2%) had diabetic level. The risks for BPH diagnosis (HR: 1.08, 95% CI: 1.03-1.13) and surgery (HR: 1.16, 95% CI: 1.09-1.24) were slightly elevated among antidiabetic drug users compared to nonusers. The association was strongest for insulin use. Similarly, risk of BPH surgery was increased in men with diabetic blood glucose compared to normoglycemic men. The risk association was attenuated by use of antidiabetic drugs. CONCLUSIONS Diabetic BGL and antidiabetic medication use, especially insulin, are associated with an elevated risk of BPH surgery compared to nondiabetic men. These findings support the roles of insulin use and untreated hyperglycemia as possible BPH risk factors.

Abstract
AIMS Hyperinsulinemia is an important causative factor of prostate enlargement in type 2 diabetes (T2D), however, clinically prostate weight increases during hypoinsulinemic condition. To investigate the pathogenesis of prostate enlargement and effects of phosphodiesterase 5 inhibitor (PDE5i), male Otsuka Long-Evans Tokushima Fatty (OLETF) and Long-Evans Tokushima Otsuka (LETO) rats were used as T2D and control, respectively. MATERIALS AND METHODS OLETF and LETO rats were treated with oral tadalafil (100 μg/kg/day) or vehicle for 12 wks from at the age of 36 wks. KEY FINDINGS Prostate weight of OLETF rats was significantly higher than that of LETO at 36 wks, and increased at 48 wks. In OLETF rats, prostate blood flow was significantly lower at 48 wks versus 36 wks. Twelve-week-tadalafil treatment increased prostate blood flow and suppressed prostate weight increase in both strains. This change was inversely correlated with changes in prostate expressions of hypoxia-inducible factor-1 alpha (HIF-1α) and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Increases with age were observed in mRNA and/or protein levels of cytokines interleukin (IL)-6, IL-8, and tumor necrosis factor-alpha (TNF-α) and cell growth factors insulin-like growth factor-1 (IGF-1), basic fibroblast growth factor (bFGF), and transforming growth factor-beta (TGF-β); especially IL-6, TNF-α, IGF-1, bFGF and TGF-β increased with T2D. Tadalafil suppressed these cytokines and growth factors. SIGNIFICANCE These data suggest chronic ischemia caused by T2D leads to oxidative stress, resulting in prostate enlargement through upregulation of several cytokines and growth factors. Treatment with PDE5i improves prostate ischemia and might prevent enlargement via suppression of cytokines and growth factors in T2D.

Abstract
Background Benign prostatic hyperplasia (BPH) is a disease that causes lower urinary tract symptoms (LUTS), which are the most common urological problem in approximately one-third of the male population aged over 50 years. Some studies have suggested that diabetes may be a risk factor for the development of BPH. However, whether diabetes aggravates the LUTS of BPH patients is still controversial. Aim To investigate the impact of diabetes mellitus on LUTS in BPH patients. Methods A literature search was conducted using Web of Science, Embase, PubMed, and China National Knowledge Infrastructure literature databases. This meta-analysis was registered in PROSPERO (registration number: CRD 42020200794). Fixed- or random-effects models were used for analysis according to heterogeneity. The results of the systematic analysis are presented as weighted mean difference (WMD) with the corresponding 95% confidence intervals (CI). Results In total, 1308 studies were retrieved from databases and 18 articles comprising 1685 cases and 4653 controls were selected for meta-analysis. The results of the meta-analysis showed that the International Prostate Symptom Score (IPSS) value and prostate volume of BPH patients with diabetes was significantly higher than that of BPH patients without diabetes. Conclusions This systematic review is the first to evaluate the impact of diabetes mellitus on LUTS in BPH patients. The results of our meta-analysis support the hypothesis that LUTS in BPH patients is increased in patients with diabetes mellitus compared with controls, which suggests that physicians should pay more attention to BPH patients with diabetes mellitus.

Abstract
INTRODUCTION Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms are highly prevalent in the aging male. Similarly, the prevalence of metabolic syndrome is increasing worldwide, with mounting evidence that these two common conditions share more than age as a predisposing factor. The objective of this study was to determine if medical management of BPH is associated with an increased risk of new-onset diabetes mellitus (DM) in routine care. METHODS This population-based, retrospective cohort study expands on a parent study of linked administrative databases identifying patients diagnosed and treated for BPH between 2005 and 2015. The primary outcome of this secondary analysis was a new diagnosis of DM after the index date of BPH diagnosis. Covariates included age, dyslipidemia, hypertension, and vascular diseases. A Cox proportional hazards regression model was used for inferential statistical analysis. RESULTS A total 129 223 men were identified with a BPH diagnosis and no prior history of DM. Of those men, 6390 (5%) were exposed to 5-alpha-reductase inhibitor (5-ARI), 39 592 (31%) exposed to alpha-blocker (AB), and 30 545 (24%) exposed to combination therapy. Compared to those men with no BPH medication use, those exposed to drugs had an increased risk of new DM. Men treated with combination therapy of 5-ARI and AB (hazard ratio [HR] 1.30, 95% confidence interval [CI] 1.25-1.35), 5-ARI monotherapy (HR 1.25, 95% CI 1.17-1.34), or AB monotherapy (HR 1.17, 95% CI 1.13-1.22) all were at higher risk of new DM diagnosis after adjusting for important covariates. When calculating the risk of a new diabetes diagnosis measured from the start of drug exposure, men treated with 5-ARIs had an increased risk of DM compared to AB monotherapy as the reference, with HR 1.12 (95% CI 1.03-1.21) for 5-ARI monotherapy and HR 1.20 (95% CI 1.14-1.25) for combination therapy. CONCLUSIONS In this large, long-term, retrospective study of men with a BPH diagnosis in routine practice, the risk of a new diagnosis of DM was greater in patients receiving medical management compared to controls. This modest but significant increased risk was highest in men treated with any 5-ARIs, in combination as well as monotherapy, compared to the ABs.

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

Abstract
PURPOSE Increasing evidence shows that many metabolic factors are involved in the progression of benign prostatic hyperplasia (BPH). We aimed to assess the relationship between the status of glucose homeostasis and prostate size in aging Chinese males undergoing transurethral resection of the prostate (TURP) for BPH. METHODS A total of 1006 medical records of BPH patients undergoing TURP were reviewed. Prostate size was measured by transrectal ultrasound. Annual total prostate (TP) and transitional zone (TZ) growth rates were calculated. According to the American Diabetes Association criteria, the patients were categorized as normoglycemic, prediabetic, or diabetic. Levels of glucose homeostasis and other variables were considered independent variables in an effort to evaluate any potential correlations using non-adjusted and multivariate-adjusted regression models. RESULTS A total of 659 individuals were included in the study. BPH patients < 70 years old and ≥ 70 years old in the normoglycemic group had a stable prostate growth rate. The change in prostate size in those younger than 70 years, however, was faster in the prediabetic and diabetic group. Further analysis revealed that abnormal glucose homeostasis was positively correlated with prostate size. In those younger than 70 years, compared with the normal glucose group, the adjusted odds ratio (OR) for TP and TZ enlargement in the prediabetic group was 2.27 (95%CI 1.29-4.00) and 3.19 (95%CI 1.78-5.72), respectively, and the adjusted ORs were 4.74 (95%CI 2.18-10.30) and 6.16 (95%CI 2.70-14.06), respectively, for men with diabetes. However there was no significant difference among men aged ≥ 70 years. CONCLUSIONS Among patients undergoing TURP, the prostate volume and growth rate were affected by different status of glucose homeostasis. Hyperglycemia may play an important role in prostate growth.

Abstract
As two most common progressive diseases of aging, type 2 diabetes mellitus (T2DM) and benign prostatic hyperplasia (BPH) were all characterized by endocrine and metabolic disorders. Here, our clinical study showed that there were significant differences in fasting blood glucose (FBG), fasting insulin (FINS), insulin resistance index (HOMA-IR) and prostate volume (PV) between simple BPH patients and BPH complicated with T2DM patients. Further analysis showed that HOMA-IR was positively correlated with PV in BPH complicated with T2DM patients. The in vitro experiment results showed that high glucose (HG) promoted EMT process in a glucose-dependent manner in human prostate hyperplasia cells (BPH-1) and prostate cancer cells (PC-3), and this pathological process was exacerbated by co-culture with insulin. Mechanistically, insulin-induced exacerbation of EMT was depended on the activation of MEK/ERK signaling pathway, and we suggested that insulin and its analogs should be used very carefully for the clinical antihyperglycemic treatment of BPH complicated with T2DM patients.

Abstract
BACKGROUND Prostatic inflammation and various proinflammatory systemic comorbidities, such as diabetes and obesity are associated with human benign prostatic hyperplasia (BPH). There is a paucity of in vivo models reflecting specific aspects of BPH pathogenesis. Our aim was to investigate the nonobese diabetic (NOD) mouse as a potential model for subsequent intervention studies. MATERIALS AND METHODS We used the NOD mouse, a model of autoimmune inflammation leading to type 1 diabetes to examine the effects of systemic inflammation and diabetes on the prostate. We assessed changes in prostatic histology, infiltrating leukocytes, and gene expression associated with aging and diabetic status. RESULTS Both stromal expansion and epithelial hyperplasia were observed in the prostates. Regardless of diabetic status, the degree of prostatic hyperplasia varied. Local inflammation was associated with a more severe prostatic phenotype in both diabetic and nondiabetic mice. Testicular atrophy was noted in diabetic mice, but prostate glands showed persistent focal cell proliferation. In addition, a prostatic intraepithelial neoplasia (PIN)-like phenotype was seen in several diabetic animals with an associated increase in c-Myc and MMP-2 expression. To examine changes in gene and cytokine expression we performed microarray and cytokine array analysis comparing the prostates of diabetic and nondiabetic animals. Microarray analysis revealed several differentially expressed genes including CCL3, CCL12, and TNFS10. Cytokine array analysis revealed increased expression of cytokines and proteases such as LDLR, IL28 A/B, and MMP-2 in diabetic mice. CONCLUSION Overall, NOD mice provide a model to examine the effects of hyperglycemia and chronic inflammation on the prostate, demonstrating relevance to some of the mechanisms present underlying BPH and potentially the initiation of prostate cancer.

Abstract
The aim of the present study was to investigate the candidate genes and pathways associated with benign prostatic hyperplasia (BPH) and diabetes. In vitro experiments were performed using normal prostatic epithelial RWPE-1 and HPr-1 cells. The cell lines were treated with a high-glucose solution and MTS and bromodeoxyuridine assays were used to assess cell viability. Transcriptome sequencing was used to screen the candidate genes. The expression of candidate genes was further verified by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blotting. A meiotic recombination 11 (MRE11) overexpression vector was designed and transfected into RWPE-1 cells to verify the function of MRE11. A streptozotocin-induced diabetic rat model was established and rat MRE11 levels were determined by RT-qPCR and immunohistochemical staining. High concentrations of glucose resulted in RWPE-1 and HPr-1 cells with high viability. Transcriptome sequencing revealed that MRE11 was downregulated when RWPE-1 cells were exposed to high-glucose conditions. When MRE11 was overexpressed, cell viability decreased and cell apoptosis was induced under high-glucose conditions. Prostatic tissues from rats were collected and assessed; MRE11 expression was observed to be decreased, which was consistent with the in vitro cell experiments. BPH may be associated with diabetes, as MRE11 expression in prostatic cells was decreased when exposed to high-glucose conditions. Therefore, MRE11 may have potential as a biomarker for the early diagnosis of BPH and diabetes.

Abstract
OBJECTIVE The objective of this study is to investigate the impact of metabolic status on associations of serum vitamin D with hypogonadism and lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH). PATIENTS AND METHODS A total of 612 men underwent physical examination, biochemical/hormonal blood testing, and transrectal prostate ultrasound. Moreover, the subjects filled out standard questionnaires for identification and grading of LUTS and hypogonadism symptoms. Parameters were statistically compared with independent t-tests and correlation analyses. RESULTS Vitamin D levels positively correlated with total testosterone (TT) but not with prostate volume or International Prostate Symptom Score (IPSS). Patients with metabolic syndrome had significantly lower vitamin D levels, which were not correlated with TT, prostate volume, or IPSS. However, vitamin D was positively correlated with TT, and negatively correlated with prostate volume and quality-of-life IPSS in subjects without metabolic syndrome. CONCLUSION The clinical usefulness of vitamin D for treatment of hypogonadism or LUTS/BPH varies according to metabolic status.

Abstract
Background: Benign prostatic hyperplasia (BPH) is the most common benign tumor in men. The etiology of BPH is still unresolved and multiple systems are likely to be involved. The effects of diabetes on urinary system are a risk factor for BPH. We then assessed the effects of diabetes on the parameters related to BPH, especially weight and volume. Methods: This study was conducted on patients with BPH who underwent surgery during 2010-2013. The patients’ demographic and clinical data including age, height, weight, history of diabetes, abdominal sonography, prostate-specific antigen(PSA), fasting blood sugar (FBS), triglyceride, and cholesterol, resected sample weight, and pathological diagnosis were extracted. Results: The mean age of all 225 patients (35 (15.6%) diabetic patients and 190 (84.4%) non-diabetic patients) who entered the study was 71.5±8.7 years. The patients were divided in to 3 body mass index (BMI) groups: 48 (21.3%) were normal, 151 (67.1%) were overweight and 26 (11.6%) were obese. The mean weight of resected prostate was higher in diabetic patients (22.9±6.9 vs 21.7±14.3, P=0.02). The resected prostate weight had a significant relationship with BMI (P=0.001), prostate–specific antigen (PSA) level (P=0.001), and prostate volume sonography (P=0.001). No significant relationship was detected between resected prostate weight with age, FBS and triglyceride however, it is significant with cholesterol. Conclusion: We concluded that diabetes has a role in the development and progression of BPH with effect on prostate weight and volume. As well, BMI is a risk factor in BPH progression.

Abstract
Serum prostate-specific antigen (PSA) is a diagnostic biomarker of prostate cancer and is possibly associated with obesity. This study aimed to explore the relationships between obesity indicators [body mass index (BMI) and waist circumference (WC)] with PSA in Chinese men. A cross-sectional study of men aged 30-85 years undergoing prostate cancer screening was conducted from August 2008 to July 2013 in Xi'an, China. Data were obtained from clinical reports, condition was recorded based on self-report including demographics, weight, height, and WC (>90 cm=obese). Fasting blood glucose (FBG) and prostate volume (PV) were assessed clinically. Patients were grouped by BMI (normal=22.9, overweight=23-27.4, obese≥27.5 kg/m2). PSA parameters of density (PSAD), PSA serum level, and PSA increasing rate per year (PSAR) were calculated per BMI and age groups (30-40, 41-59, 60-85 years). Obesity indicators (BMI and WC) and PSA parameter relationships were modeled by age-stratified linear regression. Of 35,632 Chinese men surveyed, 13,084 were analyzed, including 13.44% obese, 57.44% overweight, and 29.12% normal weight, according to BMI; 25.84% were centrally (abdominally) obese according to WC. BMI and WC were negatively associated with all PSA parameters, except PSAD and PSAR [P<0.05, BMI: β=-0.081 (95%CI=-0.055 to -0.036), WC: β=-0.101 (-0.021 to -0.015)], and independent of FBG and PV (P<0.05) in an age-adjusted model. In conclusion, obesity was associated with lower PSA in Chinese men. Therefore, an individual's BMI and WC should be considered when PSA is used to screen for prostate cancer.

Abstract
Type 2 diabetes mellitus (T2DM) is a growing epidemic associated with many adverse complications. Urological complications of diabetes mellitus in men are gaining recognition. Previously unknown associations between T2DM and risk for prostate cancer, bladder cancer, renal cell carcinomas, urinary tract infections, nephrolithiasis, penile lesions, androgen deficiency, and erectile dysfunction have been discovered. Significantly, metformin could play a role in the management of urological malignancies, and therapies used for management of these cancers could in return lead to increased risk for diabetes. In this review, we aim to bridge the gap between T2DM and urological complications by discussing the latest findings in these fields, with the ultimate goal being improved patient care on both fronts.

Abstract
BACKGROUND This nationwide population-based study investigated the risk of type 2 diabetes mellitus (DM) after 5-alpha-reductase inhibitor (5ARI) therapy for benign prostate hyperplasia (BPH) using the National Health Insurance Research Database (NHIRD) in Taiwan. METHODS In total, 1,298 adult patients newly diagnosed with BPH and who used more than 28 cumulative defined daily doses (cDDD) of 5ARI were recruited as the therapy group cohort, along with 1,2887 subjects who did not use more than 28 cDDD of 5ARI as a control group from 2002 to 2009. Each patient was monitored for 5 years (from 2003 to 2008) to identify those who subsequently developed type 2 DM. A Cox proportional hazards model was used to compare the risk of type 2 DM between the study and comparison cohorts after adjusting for possible confounding risk factors. RESULTS Patients who received 5ARI therapy had a lower cumulative rate of type 2 DM than those who did not receive 5ARI during the five-year follow-up period (3.5% vs. 5.3%, P = 0.003). In sub-group analysis, among the BPH patients aged <65 years, the five-year type 2 DM events hazard ratio (HR) of 5ARI users was lower than that of nonusers (HR: 0.47, 95% confidence interval (CI): 0.24-0.91; P = 0.026). CONCLUSIONS Therapy with 5ARI may decrease the five-year risk of type 2 DM in the BPH patients younger than 65 years. Further mechanistic research is warranted to validate the results.

Abstract
Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS) are highly prevalent in older men and represent a substantial challenge to public health. Increasing epidemiologic evidence suggests that diabetes and associated hyperglycemia and insulin resistance significantly increase the risks of BPH and LUTS. Plausible pathophysiologic mechanisms to explain these associations include increased sympathetic tone, stimulation of prostate growth by insulin and related trophic factors, alterations in sex steroid hormone expression, and induction of systemic inflammation and oxidative stress. This article presents a comprehensive update of the current understanding of clinical and epidemiologic research on diabetes and BPH/LUTS, describes hypothesized pathophysiologic mechanisms linking these conditions, and recommends future directions for research.

Abstract
BACKGROUND It has been suggested that individuals with metabolic syndrome (MetS) may be prone to developing benign prostatic hyperplasia (BPH), but the direction of causality remains uncertain. The objective of this cross-sectional study was to evaluate the association between BPH and MetS in men who were referred to surgery for BPH. We were interested in identifying the anthropometric, metabolic, and hormonal factors that potentially influence the risk of both conditions. METHODS The study was conducted on 128 males with BPH and 141 without BPH (the control group). Fasting glucose, insulin, lipid profiles, total and free testosterone, estradiol, sex-hormone binding protein (SHBG), dehydroepiandrosterone sulfate (DHEA-S), homeostasis model assessment (HOMA-IR) index, and lipid accumulation product (LAP) were all evaluated. RESULTS The prevalence of MetS was higher in patients with BPH than in the controls (58 vs. 41 %; P = 0.007). In comparison to the controls, patients with BPH had higher levels of cholesterol, low density lipoproteins, DHEA-S, insulin, and HOMA-IR, but lower levels of high-density lipoproteins (HDL), estradiol, and SHBG. The significant predictors of BPH were MetS (OR = 1.961), age (OR = 0.11), HDL (OR = 0.91), insulin (OR = 1.224), SHBG (OR = 0.98), and estradiol (OR = 0.978). Waist circumference and LAP inversely correlated with total and free testosterone and SHBG. CONCLUSIONS Our study confirmed the frequent coexistence of MetS and BPH. This association seems to be a consequence of the MetS-related metabolic derangements, changes in the sex-hormone milieu, and lowered SHBG levels.

Abstract
Purpose Aldehyde dehydrogenase 2 (ALDH2) is a well-known gene involved in alcohol and aldehyde metabolism. Moreover, recent studies have reported associations between ALDH2 and age-related disorders. Benign prostate hyperplasia (BPH) is an age-related disorder and genetic factors may contribute to its onset. In this study, we investigated the association of a well-studied ALDH2 single nucleotide polymorphism (SNP), rs671, with the onset and clinical features of BPH. Methods A total of 222 BPH patients and 214 control subjects were genotyped. The clinical features of the BPH patients (prostate volume, prostate-specific antigen level, and International Prostatic Symptom Score) were analyzed. Results The results show that rs671 was only associated with the volume of BPH in genotype and allele frequencies (P<0.05). Conclusion We propose that rs671 is an Asian-specific SNP in ALDH2 that may affect the disease progression of BPH in the Korean population.
