Impact of statins as immune-modulatory agents on inflammatory markers in adults with chronic diseases: A systematic review and meta-analysis. PLoS One 2025; 20:e0323749. [PMID: 40440323 PMCID: PMC12121830 DOI: 10.1371/journal.pone.0323749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Accepted: 04/15/2025] [Indexed: 06/02/2025] Open
Abstract
While numerous studies have extensively documented the pleiotropic effects of statins, including their capacity to reduce inflammation, there is a lack of research estimating the anti-inflammatory effectiveness of statins among individuals with chronic diseases. This meta-analysis evaluates the effect of statin therapy on inflammatory markers and the lipid profile in patients with chronic diseases by analysing evidence from randomized controlled trials (RCTs). We conducted a systematic review and searched articles published between 1st January 1999 and 31st December 2023 in databases including PubMed, Web of Science, Scopus, and Cochrane. The meta-analysis was performed using random effects models and inverse variance. Effect measures were mean differences (MD) and 95% confidence intervals (CI). Collectively, statins significantly reduced IL-6 (MD = -0.24 ng/dL [95% CI, -0.36 to -0.13], I2 = 98.3%, p < 0.001), TNF-α (MD = -0.74 ng/dL [95% CI, -1.08 to -0.40], I2 = 98.8%, p < 0.001); and CRP (MD = -1.58 mg/L [95% CI, -2.22 to -0.94], I2 = 86.5%, p < 0.001). Notably, atorvastatin demonstrated the most significant reduction in IL-6 and TNF-α levels, while fluvastatin and rosuvastatin displayed the greatest impact on decreasing CRP and LDL-C levels, respectively. Stratification by a longer treatment duration of more than four months revealed that atorvastatin achieved the most significant reduction in IL-6 and TNF-α. In conclusion, statin therapy not only regulates the lipid profile but also reduces systemic inflammatory biomarkers. Prolonged administration of statins led to a more substantial reduction in IL-6 and TNF-α, with atorvastatin exhibiting the greatest effect in our analysis.

Abstract
Background As one of the most prevalent chronic non-communicable diseases affecting aging males, the burden of benign prostatic hyperplasia is growing over the world. Our study aims at investigating the potential relationships between various blood biomarkers and benign prostatic hyperplasia (BPH) in middle-aged and older men in European and East Asian population cohorts. Methods We included 229 022 male adults from the UK Biobank (UKB) and 20 284 male adults from the China Health and Retirement Longitudinal Study (CHARLS) in this study. Forty-four blood biomarkers in UKB cohort and 16 blood biomarkers in the CHARLS cohort were analysed to examine their association with benign prostatic hyperplasia. Cox, logistic analyses and restricted cubic spline models were used to investigate linear and nonlinear longitudinal associations. Results In our research, elevated high-density lipoprotein cholesterol showed significant associations with a decreased risk of benign prostatic hyperplasia, and these associations remained significant after accounting for potential covariates both in UKB cohort (hazard ratio (HR) = 0.83; 95% CI = 0.79-0.88, P < 0.001) and CHARLS cohort (odds ratio (OR) = 0.992; 95% CI = 0.985-0.999, P = 0.033). Apolipoprotein A was also found to be inversely associated with BPH (HR = 0.76; 95% CI = 0.70-0.81, P < 0.001). L-shaped relationships were discovered between level of high-density lipoprotein cholesterol and apolipoprotein A with incidence of benign prostatic hyperplasia. Conclusions This large prospective biomarker-based study highlights that high-density lipoprotein (HDL) cholesterol and apolipoprotein A are significant protective factors against the development of BPH, with L-shaped associations suggesting an optimal protective range. In contrast, biomarkers related to glucose metabolism, inflammation, and hormone levels were not found to significantly influence BPH progression. Our findings support the potential involvement of lipid biomarkers in the early stages of BPH development, suggesting that future strategies should prioritise lipid-related pathways in the prevention and management of BPH.

[PMID: 38297152 DOI: 10.1038/s41391-024-00793-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 12/20/2023] [Accepted: 01/16/2024] [Indexed: 02/02/2024]
Abstract
BACKGROUND Autophagy is a well-conserved catabolic process that plays a key role in cell homeostasis. In the prostate, defective autophagy has been implicated in the genesis and progression of several pathological conditions. AIM The present review explored the autophagy pathway in prostate-related dysfunctions, focusing on prostate cancer (PCa), benign prostatic hyperplasia (BPH) and prostatitis. RESULTS Impaired autophagy activity has been shown in animal models of BPH and prostatitis. Moreover, autophagy activation by specific and non-specific drugs improved both conditions in pre-clinical studies. Conversely, the efficacy of autophagy inducers in PCa remains controversial, depending on intrinsic PCa characteristics and stage of progression. Intriguingly, autophagy inhibitors have shown beneficial effects in PCa suppression or even to overcome chemotherapy resistance. However, there are still open questions regarding the upstream mechanisms by which autophagy is deregulated in the prostate and the exact role of autophagy in PCa. The lack of specificity and increased toxicity associated with the currently autophagy inhibitors limits its use clinically, reflecting in reduced number of clinical data. CONCLUSION New therapeutic strategies to treat prostatic diseases involving new autophagy modulators, combination therapy and new drug formulations should be explored. Understanding the autophagy signaling in each prostatic disease is crucial to determine the best pharmacological approach.

Eur J Pharmacol 2023; 950:175762. [PMID: 37164119 DOI: 10.1016/j.ejphar.2023.175762] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 05/01/2023] [Accepted: 05/01/2023] [Indexed: 05/12/2023]
Abstract
Benign prostatic hyperplasia (BPH) is characterized by non-malignant enlargement of prostate cells causing many lower urinary tract symptoms. BPH pathogenesis includes androgens receptors signaling pathways, oxidative stress, apoptosis, and possibly changes in IGF-1/PI3K/AKT/FOXO pathway. Altogether, modulating IGF-1/PI3K/AKT/FOXO signaling along with regulating oxidative stress and apoptosis might preserve prostatic cells from increased proliferation. Beyond statins' common uses, they also have anti-inflammatory, antioxidant, and anti-tumor effects. This study aims to determine simvastatin's beneficial effect on testosterone-induced BPH. Rats were randomly allocated into four groups, 9 rats each. The control group received olive oil subcutaneously and distilled water orally for 30 consecutive days. The second group received simvastatin (20 mg/kg, p.o.) dissolved in distilled water. The BPH-induced group received testosterone enanthate (3 mg/kg, s.c.) dissolved in olive oil, and the BPH-induced treated group received both simvastatin and testosterone. Testosterone significantly increased prostate index and severity of histopathological alterations in prostate tissues as well as 5-alpha reductase enzyme level in contrast to simvastatin treatment that reversed the testosterone-induced alterations in these parameters. Likewise, testosterone up-regulated IGF-1/PI3K/AKT signaling pathway and down-regulated FOXO transcription factor. It also decreased apoptotic markers level in prostatic tissue BAX, caspase-3, and caspase-9, while it elevated Bcl-2 level. In addition, it alleviated reduced GSH and GPX5 levels and SOD activity. Simvastatin treatment significantly opposed testosterone's effect on all aforementioned parameters. In conclusion, this study demonstrates that simvastatin is a possible treatment for BPH which may be attributed to its effect on IGF-1/PI3K/AKT/FOXO signaling pathway as well as anti-oxidant and apoptotic effects.

Simvastatin Improves Benign Prostatic Hyperplasia: Role of Peroxisome-Proliferator-Activated Receptor-γ and Classic WNT/β-Catenin Pathway. Int J Mol Sci 2023; 24:ijms24054911. [PMID: 36902342 PMCID: PMC10003121 DOI: 10.3390/ijms24054911] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 02/26/2023] [Accepted: 02/27/2023] [Indexed: 03/08/2023] Open
Abstract
Benign prostatic hyperplasia (BPH) is a common disease in elderly men with an uncertain etiology and mechanistic basis. Metabolic syndrome (MetS) is also a very common illness and is closely related to BPH. Simvastatin (SV) is one of the widely used statins for MetS. Peroxisome-proliferator-activated receptor gamma (PPARγ), crosstalking with the WNT/β-catenin pathway, plays important roles in MetS. Our current study aimed to examine SV-PPARγ-WNT/β-catenin signaling in the development of BPH. Human prostate tissues and cell lines plus a BPH rat model were utilized. Immunohistochemical, immunofluorescence, hematoxylin and eosin (H&E) and Masson's trichrome staining, construction of a tissue microarray (TMA), ELISA, CCK-8 assay, qRT-PCR, flow cytometry, and Western blotting were also performed. PPARγ was expressed in both prostate stroma and epithelial compartments and downregulated in BPH tissues. Furthermore, SV dose-dependently triggered cell apoptosis and cell cycle arrest at the G0/G1 phase and attenuated tissue fibrosis and the epithelial-mesenchymal transition (EMT) process both in vitro and in vivo. SV also upregulated the PPARγ pathway, whose antagonist could reverse SV produced in the aforementioned biological process. Additionally, crosstalk between PPARγ and WNT/β-catenin signaling was demonstrated. Finally, correlation analysis with our TMA containing 104 BPH specimens showed that PPARγ was negatively related with prostate volume (PV) and free prostate-specific antigen (fPSA) and positively correlated with maximum urinary flow rate (Qmax). WNT-1 and β-catenin were positively related with International Prostate Symptom Score (IPSS) and nocturia, respectively. Our novel data demonstrate that SV could modulate cell proliferation, apoptosis, tissue fibrosis, and the EMT process in the prostate through crosstalk between PPARγ and WNT/β-catenin pathways.

Abstract
OBJECTIVE To evaluate the association between IL-6 in prostatic tissue/blood sample and BPH-LUTS, so as to preliminarily discover an indicator of inflammation that could show the severity of LUTS. PATIENTS AND METHODS The prostatic tissues and blood samples were collected from 56 patients who underwent transurethral plasmakinetic resection of the prostate (TUPKRP). The association between IL-6 detected on prostatic tissues/blood sample and LUTS parameters, including international prostate symptom score (IPSS), peak flow rate (Qmax) and urodynamic parameters were analyzed with SPSS version 18.0, and p-value <0.05 was chosen as the criterion for statistical significance. RESULTS The TPSA and prostate volume (PV) were found to be higher in the inflammation group (p=0.021, 0.036). There was a positive association between prostate tissue inflammation and LUTS ([IPSS, storage symptoms score (SSS), voiding symptoms score (VSS), p<0.05], [Qmax, p=0.025], [obstruction, p=0.027] and [AUR, p=0.018]). The level of serum IL-6 was significantly higher in inflammatory group (p=0.008). However, no differences were observed in different degrees of inflammation (p=0.393). The level of IL-6 in prostatic tissue significantly increased with the degree of inflammation (p<0.001), and the intensity of IL-6 expression was statistically correlative with the degree of inflammation (p<0.001). The IL-6 expression in prostatic tissue was statistically relevant with IPSS (p=0.018) and SSS (p=0.012). CONCLUSION IL-6 expression in prostatic tissue is associated with storage IPSS, suggesting chronic inflammation might contribute to storage LUTS.

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

Abstract
BACKGROUND Because it is unclear whether lower urinary tract symptoms (LUTS) are associated with cardiovascular disease (CVD) in the Japanese population, we explored the association in general Japanese men aged 55-75 years. METHODS AND RESULTS The cross-sectional study included male participants who had both national health checkup data and the International Prostate Symptom Score (IPSS) in the same calendar year between 2009 and 2017. LUTS severity was evaluated by IPSS. A robust Poisson regression model was used to assess the association between LUTS severity and the composite CVD outcome [coronary artery disease (CAD), stroke, or atrial fibrillation (AF)] and each component of the composite outcome. Prevalence ratio (PR) was adjusted for conventional cardiovascular risk factors. Of 16,781 male participants (mean age, 67±5 years), mild LUTS were observed in 9,243 (55.1%); moderate, 6,445 (38.4%); and severe, 1,093 (6.5%). Compared with the mild LUTS group, moderate LUTS [PR 1.18, 95% confidence interval (CI) 1.10-1.25, P<0.001] and severe LUTS (PR 1.38, 95% CI 1.24-1.53, P<0.001) were significantly associated with a higher prevalence of CVD. LUTS severity was associated with higher prevalence of CAD and stroke, but not AF. CONCLUSIONS The severity of LUTS was associated with a higher prevalence of CVD, especially CAD and stroke, independent of conventional CVD risk factors.

A systematic review and meta-analysis. Cent European J Urol 2021; 74:388-421. [PMID: 34729231 PMCID: PMC8552938 DOI: 10.5173/ceju.2021.132.r1] [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: 11/16/2020] [Revised: 06/15/2021] [Accepted: 06/30/2021] [Indexed: 11/22/2022] Open
Abstract
INTRODUCTION The clinical effect of pharmacotherapy on prostate morphometric parameters is largely unknown. The sole exception is 5α-reductase inhibitors (5-ARI) that reduce prostate volume and prostate-specific antigen (PSA). This review assesses the effect of pharmacotherapy on prostate parameters effect on prostate parameters, namely total prostate volume (TPV), transitional zone volume (TZV), PSA and prostate perfusion. MATERIAL AND METHODS We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) reporting on morphometric parameters' changes after pharmacotherapy, as primary or secondary outcomes. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RCTs' quality was assessed by the Cochrane tool and the criteria of the Agency for Healthcare Research and Quality. The effect magnitude was expressed as standard mean difference (SMD). The study protocol was published on PROSPERO (CRD42020170172). RESULTS Sixty-seven RCTs were included in the review and 18 in the meta-analysis. The changes after alpha-blockers are comparable to placebo. Long-term studies reporting significant changes from baseline, result from physiologic growth. Finasteride and dutasteride demonstrated large effect sizes in TPV reduction ([SMD]: -1.15 (95% CI: -1.26 to -1.04, p <0.001, and [SMD]:-0.66 (95% CI: -0.83 to -0.49, p <0.001, respectively), and similar PSA reductions. Dutasteride's effect appears earlier (1st vs 3rd month), the changes reach a maximum at month 12 and are sustained thereafter. Phosphodiesterase-5 (PDE-5) inhibitors have no effect on morphometric parameters. Phytotherapy's effect on TPV is non-significant [SMD]: 0.12 (95% CI: -0.03 to 0.27, p = 0.13). Atorvastatin reduces TPV as compared to placebo (-11.7% vs +2.5%, p <0.01). Co-administration of testosterone with dutasteride spares the prostate from the androgenic stimulation as both TPV and PSA are reduced significantly. CONCLUSIONS The 5-ARIs show large effect size in reducing TPV and PSA. Tamsulosin improves perfusion but no other effect is evident. PDE-5 inhibitors and phytotherapy do not affect morphometric parameters. Atorvastatin reduces TPV and PSA as opposed to testosterone supplementation.

[PMID: 33499215 PMCID: PMC7865704 DOI: 10.3390/jcm10030416] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 01/07/2021] [Accepted: 01/18/2021] [Indexed: 01/22/2023] Open
Abstract
Previous data have shown that patients with metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement (BPE) could be refractory to the medical treatment. In this context, the evidence suggests a role for statin use in LUTS/BPE patients. The present systematic review aimed to evaluate the impact of statins on the treatment of men with LUTS/BPE. This review has been registered on PROSPERO (CRD42019120729). A systematic review of English-language literature was performed up to January 2020 in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA statement) criteria. Retrieved studies had to include adults with LUTS connected to BPE treated with statins drugs for metabolic syndrome. After removing duplicates, a total of 381 studies were identified by the literature search and independently screened. Of these articles, 10 fit the inclusion criteria and were further assessed for eligibility. Data from our systematic review suggest that a long-term therapy with statins, at least 6 months, is required to achieve significant impacts on prostate tissue and LUTS. Moreover, besides statins' direct activity, the risk reduction of LUTS might be connected to the improvement of hypercholesterolemia and MetS. The role of statins for the treatment of LUTS/BPE may be beneficial; however, evidence from robust studies is not enough, and more clinical trial are required.

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

Abstract
BACKGROUND We evaluated the optimal high-density lipoprotein cholesterol level for benign prostatic hyperplasia (BPH) prevention in men not taking statin medication using a large historical cohort. METHODS We initially selected 130 454 men who underwent health checkups in 2009 from the National Health Information Database of the National Health Insurance Service. After excluding 36 854 men with BPH in 2009, and 45 061 men for statin use, 48 539 men were ultimately included in the analysis. A Kaplan-Meier analysis and multivariable Cox regression analysis was performed to assess the optimal high-density lipoprotein cholesterol level for preventing BPH. RESULTS High-density lipoprotein cholesterol levels were less than 40 mg/dL in 7431 (15.3%) men, 40 to 49 in 15 861 (32.7%), 50 to 59 in 15 328 (27.5%), and greater than or equal to 60 in 11 919 (24.6%). The overall cumulative incidence of BPH was 4.4%, 8.7%, 13.0%, and 17.8% at the 1-, 2-, 3-, and 4-year follow-up periods, respectively. In multivariable analysis, high-density lipoprotein greater than or equal to 60 mg/dL were significantly associated with a decreased incidence of BPH, as were age, residence, income, body mass index, diabetes, hypertension, triglyceride, and increased annual clinic visits, especially in men in their 40s. CONCLUSION Elevated serum high-density lipoprotein cholesterol levels were negatively associated with BPH incidence. In addition, maintaining high-density lipoprotein greater than or equal to 60 mg/dL was associated with a decreased BPH incidence compared with high-density lipoprotein less than 40 mg/dL, especially in men in their 40s.

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

Abstract
BACKGROUND The influence of a previous transurethral resection of the prostate (TURP) on the outcomes of radical prostatectomy (RP) is still controversial. Therefore, we performed a meta-analysis to evaluate the perioperative, functional and oncological outcomes of RP with or without a previous TURP. METHODS We conducted a computerized literature search of PubMed, Embase, and the Cochrane Library and included 15 retrospective studies evaluating RPs with or without a previous TURP in this meta-analysis. RESULTS Fifteen studies, including 6,840 cases, were analyzed. RP after a previous TURP were related to smaller prostate volumes (WMD: -6.93 cm3; 95% CI, -10.89 to -2.97; P<0.001), lower preoperative prostate-specific antigen (PSA) levels (WMD: -1.51; 95% CI, -2.49 to -0.53; P=0.002), longer operative times (WMD: 13.22 min; 95% CI, 4.55 to 21.89 min; P=0.003), more blood loss (WMD: 55.38 mL; 95% CI, 12.35 to 98.41 mL; P=0.01), higher overall complication rates (OR =1.98; 95% CI, 1.27 to 3.08; P=0.002), longer hospital stays (WMD: 1.16 days; 95% CI, 0.65 to 1.67; P<0.001), longer duration of catheter (WMD: 0.60 days; 95% CI, 0.56 to 0.64; P<0.001), higher positive surgical margin rates (OR =1.30; 95% CI, 1.09 to 1.55; P=0.004), lower complete continence rates at 3 months (OR =0.67; 95% CI, 0.56 to 0.81; P<0.001), 6 months (OR =0.52; 95% CI, 0.31 to 0.88; P=0.01), 12 months (OR =0.59; 95% CI, 0.46 to 0.74; P<0.001), and lower potency rates at 12 months (OR =0.62; 95% CI, 0.51 to 0.77; P<0.001). Subgroup analysis indicated that open RP after previous TURP could achieve better outcomes. CONCLUSIONS RP after a previous TURP leads to worse perioperative, oncological, and functional outcomes. For these patients an open procedure is recommended. Due to the low number of studies and known biases, further large-scale studies are needed to support this result.

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

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

Abstract
Current evidence suggests that statin use decreases the incidence of cardiovascular diseases (CVD) through reducing LDL cholesterol and decreasing inflammation. Metabolic syndrome (MetS) is usually associated with increased inflammatory markers and increased risk of CVD. We conducted a systematic review and meta-analysis to determine the effect of statin use on inflammatory markers including C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1 (IL-1) among patients with MetS and related disorders. PubMed, EMBASE, Web of Science databases, and Cochrane Library were searched for randomized controlled trials (RCTs) through April 2018. Three independent investigators evaluated study eligibilities, extracted data, and assessed study quality using the Cochrane Collaboration risk of bias tool and Jadad's quality scales. Heterogeneity was determined using Cochran's Q statistic and I-square (I2) test. Based on the heterogeneity results, we pooled data using random-effect or fixed effect models presented as standardized mean differences (SMD) and corresponding 95% confidence intervals (CI). One hundred thirteen RCTs (19,644 patients) were included in our meta-analysis. The pooled results using random effects model showed that statin use statistically significantly decreased CRP level (SMD= -0.97; 95% CI, -1.10, -0.85; P < 0.001; I2: 95.1%), TNF-α (SMD= -1.88; 95% CI, -2.40, -1.38; P < 0.001; I2: 97.2%), IL-6 (SMD= -1.67; 95% CI, -1.98, -1.34; P < 0.001; I2: 96.5%), and IL-1 concentrations (SMD= -8.35; 95% CI, -10.49, -6.22; P < 0.001; I2: 98.4%) among patients with MetS and related disorders. Our meta-analysis showed beneficial effects of statin use on reducing inflammatory markers in patients with MetS and related disorders.

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

Transurethral resection of the prostate with preservation of the bladder neck decreases postoperative retrograde ejaculation. Wideochir Inne Tech Maloinwazyjne 2018; 14:96-101. [PMID: 30766635 PMCID: PMC6372866 DOI: 10.5114/wiitm.2018.79536] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Accepted: 10/07/2018] [Indexed: 11/17/2022] Open
Abstract
Introduction Even though transurethral resection of the prostate (TURP) is the standard surgical treatment for benign prostatic hyperplasia (BPH), there is a high rate of postoperative retrograde ejaculation. Aim To evaluate the effectiveness of TURP with preservation of the bladder neck in comparison with that of standard TURP. Material and methods This is a retrospective study. 137 men with BPH were divided into two groups: TURP with preservation of the bladder neck and standard TURP were performed respectively in group A and group B. The patients were evaluated preoperatively and at 3, 6 and 12 months after surgery by International Prostate Symptom Score (IPSS), health-related quality of life (HRQL) score, maximum urinary flow rate (Qmax), postvoid residual urine volume (PVR) and the rate of complications including retrograde ejaculation. Results There was no statistically significant difference between groups in terms of the operative duration, catheterization period, hemoglobin decrease, and hospital stay. At the 3-month follow-up, the rates of incontinence and retrograde ejaculation in group A were lower than those in group B. At the 6- and 12-month follow-ups, the difference in the frequency of retrograde ejaculation remained constantly stable whereas the incontinence rates were similar in both groups. The IPSS, HRQL score, Qmax, PVR and the rate of complications including hematuria, clot retention, urinary tract infection, urethral stricture, and bladder neck contracture evaluated at 3, 6 and 12 months also displayed a very similar response in the two groups. Conclusions Comparable with standard TURP, TURP with preservation of the bladder neck appears to provide a satisfactory clinical outcome in decreasing early postoperative incontinence and lowering the rate of retrograde ejaculation.

Abstract
BACKGROUND The purpose of this narrative review is to evaluate the role of prostatic inflammation as a treatment target for lower urinary tract symptoms (LUTS) due to benign prostatic obstruction (BPO) and provide an update on the available therapies. METHODS An extensive literature search was conducted for studies on established and investigational treatments with anti-inflammatory mechanism of action that has been assessed for the management of male LUTS due to BPO. RESULTS Data on phosphodiesterase 5 inhibitors, nonsteroidal anti-inflammatory drugs, vitamin D3 receptor analogs, phytotherapy, statins, and lifestyle changes have been reviewed and analyzed. Preclinical evidence has shown the anti-inflammatory effect of these treatments on prostate. However, there is a wide variation in the degree of mature of each therapy. In addition, there are significant differences between the studies in terms of design, number of patients, and duration of follow-up. CONCLUSIONS Several drugs classes have been investigated for their impact on prostatic inflammation and improvement of male LUTS. The reviewed data support the rationale for use of agents that may alter and improve the inflammatory environment in the prostate in men with LUTS, but further high-quality long-term studies are required for the exact positioning of the new drugs in daily practice.

Abstract
Cyclodextrins play an important role in supramolecular chemistry acting as building blocks than can be cross-linked by various linker molecules forming nano-porous structures called nanosponges (NS). NS have the ability to enhance the stability, solubility and bioavailability of various actives. This work aimed at elaborating rosuvastatin (ROS) loaded NS to improve its oral bioavailability. Carboxylate-linked NS were synthesized by reacting β-CD with pyromellitic dianhydride (PDA) at different molar ratios under specific conditions. ROS-loaded NS were prepared by lyophilisation technique and characterized for particle size, zeta potential, entrapment efficiency and drug release. Occurrence of cross-linking and ROS incorporation within the NS were assessed by DSC, FT-IR and SEM micrographs. NS prepared at a molar ratio of 1:6 of β-CD: PDA demonstrated the highest entrapment efficiency (88.76%), an optimum particle size of 275nm, a narrow size distribution (PDI of 0.392), and zeta potential of -61.9 indicating good colloidal stability. In vivo oral pharmacokinetics study in male Sprague Dawley rats showed that ROS-NS provided an outstanding enhancement in oral bioavailability compared to drug suspension and marketed tablets besides their physicochemical stability for 3month. Accordingly, ROS-NS represent a superior alternative to the conventional marketed formulation for effective ROS delivery.

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

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

Statin Use, Serum Lipids, and Prostate Inflammation in Men with a Negative Prostate Biopsy: Results from the REDUCE Trial. Cancer Prev Res (Phila) 2017; 10:319-326. [PMID: 28487295 DOI: 10.1158/1940-6207.capr-17-0019] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2017] [Revised: 02/21/2017] [Accepted: 03/20/2017] [Indexed: 01/02/2023]
Abstract
Statin use is associated with lower advanced prostate cancer risk. In addition to cholesterol lowering, statins have systemic anti-inflammatory properties. However, their effect on histologic prostate inflammation is not well understood, particularly among men at increased prostate cancer risk but with a negative prostate biopsy. We examined associations between serum lipid levels, statin use, and histologic prostate inflammation using data from 6,655 men with a negative baseline prostate biopsy in the REduction by DUtasteride of prostate Cancer Events (REDUCE) trial. Statin use and lipid levels [total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides] were assessed at baseline. Inflammation was assessed by central review. Logistic regression was used to examine the effects of lipids and statin use on presence and extent of chronic and acute prostate inflammation [none, moderate (<20%), severe (≥20% biopsy cores)]. Chronic and acute inflammation affected 77% and 15% of men, respectively. Men with high HDL (≥60 vs. <40 mg/dL) had reduced presence of acute inflammation [OR, 0.79; 95% confidence interval (CI), 0.63-0.99] and were less likely to have severe acute inflammation (OR, 0.66; 95% CI, 0.45-0.97), but there were no other associations between lipids and inflammation. Statin users had reduced presence of chronic inflammation (OR, 0.81; 95% CI, 0.69-0.95) and were less likely to have severe chronic (OR, 0.80; 95% CI, 0.68-0.95) and severe acute inflammation (OR, 0.73; 95% CI, 0.53-1.00), relative to non-users. Given the possible role for inflammation in prostate cancer, the inverse association between statins and prostate inflammation suggests a mechanism linking statins with lower advanced prostate cancer risk.
