Serum levels of prostate specific antigen, free PSA, [-2]proPSA, fPSA/tPSA ratio, Prostate Health Index, and glycosylation patterns of free PSA in patients with benign prostatic hyperplasia pharmacotherapy. Prostate 2024. [PMID: 39327946 DOI: 10.1002/pros.24801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2024] [Revised: 08/27/2024] [Accepted: 09/17/2024] [Indexed: 09/28/2024]
Abstract
BACKGROUND The medication used to treat benign prostate hyperplasia (BPH), a common condition in men over 50 years of age, can alter the levels of biomarkers used in prostate cancer detection. Commonly used medications for BPH include alpha-blockers, 5-alpha reductase inhibitors (5-ARIs), and muscarinic antagonists. We studied the impact of these drugs on total prostate-specific antigen (tPSA), free PSA (fPSA), [-2]proPSA, fPSA/tPSA ratio, and the Prostate Health Index (PHI), as well as novel potential biomarkers in the form of glycan composition of fPSA. PATIENTS AND METHODS Serum samples were collected from 564 males with BPH, with a mean age of 68.5 years. The samples were used to measure levels of tPSA, fPSA, and [-2]proPSA. The fPSA/tPSA and PHI were then calculated. The glycan composition of fPSA was analyzed using lectin-based glycoprofiling. Pharmacotherapy data was collected from the patients' medical records. RESULTS Alpha-blocker monotherapy was associated with higher fPSA and fPSA/tPSA ratio, and decreased PHI. Levels of tPSA were not impacted. Alpha-blocker and 5-ARI dual therapy was associated with reduced levels of fPSA, [-2]proPSA, and PHI. Therapy combining alpha-blockers and antimuscarinic agents did not significantly influence biomarker levels apart from an increase in a Maackia amurensis lectin-recognized glycan originating in fPSA. CONCLUSION BPH pharmacotherapy notably affects prostate cancer biomarkers. Recognizing the impact of pharmacotherapy is crucial for achieving an accurate diagnosis of prostate cancer and for planning treatment.

Abstract
INTRODUCTION Benign prostatic hyperplasia (BPH) is a condition that affects over 50% of men as they enter their fifth decade of life, often leading to lower urinary tract symptoms (LUTS). Primary treatment options include alpha blockers, 5-alpha reductase inhibitors, and phosphodiesterase-5 inhibitors. However, these medications can have some side effects, and there is a noticeable dearth of information addressing the long-term use of these medications. Thus, the exploration of all treatment modalities helps ensure patients receive personalized and effective care. Consequently, the primary objective of this review is to identify potential emerging medications for the treatment of BPH. AREAS COVERED We conducted an extensive review of articles discussing pharmacotherapy for BPH spanning the last 15 years. Our information gathering process involved Scopus, PubMed-MEDLINE, Cochrane, Wiley Online Library Google Scholar, ClinicalTrials.gov, and the PharmaProjects database. This approach ensures that readers gain an in-depth knowledge of the existing therapeutic agents as well as promising avenues for managing BPH. EXPERT OPINION BPH treatment targets a patient's specific constellation of symptoms. Therefore, a broad knowledge base encompassing various treatment options is paramount in ensuring optimal treatment. Looking forward, the emphasis on personalization promises to reshape the landscape of BPH treatment and improve patient outcomes.

Abstract
AIMS To address the predictive factors of a successful voiding after bladder outflow resistance reduction surgery (BORRS) in men presenting with acute or chronic urinary retention (UR). METHODS A think tank (TT) of ICI-RS was gathered in 2023, Bristol, UK, to discuss several aspects of the problem, such as the pathophysiology of UR, the clinical and urodynamic evaluation of men with UR and whether it is possible to predict which men will be able to successfully void after treatment with contemporary surgical options. RESULTS The TT agreed that successful voiding after BORRS depends on several factors but that a strong recommendation cannot be made regarding preoperative evaluation and whether there are predictive factors of success because of the heterogeneity of patients and methodology in published trials. The diagnosis of obstruction in men with UR may be challenging when there is apparent reduced detrusor contraction during urodynamic studies. Even in the absence of bladder contractility there is documentation of such cases that have voided adequately after BORRS. Still, detrusor underactivity and inadequate relief of prostatic obstruction are the main causes of an unsuccessful voiding after BORRS. Conventional resection and enucleation methods remain the most successful surgeries in relieving UR in men, whereas the efficacy of minimally invasive surgical treatments needs to be assessed further. CONCLUSION Research is needed to understand the pathophysiology of UR and the predictors of successful voiding after different types of BORRS in men with UR.

Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) commonly causes lower urinary tract symptoms (LUTS) in men. Holmium (HoLEP) and thulium (ThuLEP) laser enucleation are established techniques for BPH treatment. Thulium fiber laser (TFL) for prostate enucleation (ThuFLEP) shows promising outcomes. METHODS A prospective randomized multicenter study was conducted. Patients with BPH and LUTS unresponsive to medical therapy were enrolled. Preoperative, surgical, perioperative and postoperative data were recorded with follow-up at 3 and 6 months. The primary outcome was functional improvement, and the secondary outcome was safety in terms of complications. RESULTS Two hundred patients were included (HoLEP 100, ThuFLEP 100). No significant baseline difference was found between groups. At 3 and 6 months we found statistically significant improvements from baseline for both HoLEP and ThuFLEP in efficacy: International Prostatic Symptoms Score (IPSS), IPSS-Quality of Life (QoL), maximum urinary flow rate (Qmax), and post-void residual volume (PVR; P<0.05). At 6 months, mean±SD IPSS, IPSS-QoL, Qmax, and PVR for HoLEP vs. ThuFLEP were 5.8±4.9 vs. 4.8±5.0 points (P=0.57), 1.6±1.4 vs. 0.7±1.1 points (P=0.09), 29.9±12.5 vs. 29.6±8.0 mL/s (P=0.8), and 16.3±17.7 vs. 15.5±13.4 mL (P=0.92), respectively. No intraoperative complication was recorded. No Clavien-Dindo ≥III complications occurred during hospitalization. After 6 months, 8 (8%) and 6 (6%) patients reported mild stress urinary incontinence in HoLEP and ThuFLEP groups, respectively (P=0.24). Urethral stenosis was observed in 3 men (3%) in the HoLEP group and 1 subject (1%) in the ThuFLEP group (P=0.72). CONCLUSIONS HoLEP and ThuFLEP are effective and safe for BPH treatment, with comparable functional outcomes and complication rates at 6 months. Further research is needed to confirm these findings.

Abstract
AIMS Benign prostatic enlargement (BPE) can impact lower urinary tract function due to its potential progression to benign prostatic obstruction (BPO). Treatment options include removal of the obstruction by surgery or through use of therapeutics designed to slow growth or reduce tissue stress imposed by muscular stromal components. Inflammation and development of fibrosis can also raise intrinsic tissue stress within the gland, further impacting obstruction. Outflow tract obstruction can also impact emission and ejaculation if the obstruction persists. METHODS This review summarizes an ICI-RS think tank considering novel drug treatments that might address BPO caused by progressive development of BPE, as well as manage decompensation changes to bladder function. RESULTS Topics included recent advances in our understanding of pathological changes occurring to the prostate and other lower urinary tract tissues during progressive development of BPE, and how prevention or reversal might benefit from the identification of novel drug targets. These included contractile properties of prostatic tissues, the impact of BPE and its effects on bladder function, the deposition of intramural fibrotic tissue with protracted BPO, the role of inflammation in the development of BPE and its progression to BPO. In particular, we discussed current therapeutic options for treating BPE/BPO, and new therapeutic targets, what they treat and their advantage over current medications. CONCLUSION Several new drug targets were identified, including soluble guanylate cyclase (sGC), the receptor for nitric oxide (NO•), and sGC activators that promotes sGC-mediated cGMP production when sGC is inactivated and unresponsive to NO•.

Abstract
BACKGROUND Research has demonstrated that social isolation and loneliness are linked to functional disability in older adults. With the intensification of global aging, functional disability and lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) have become common public health issues affecting elderly men. METHODS This study utilized data from the CHARLS database. The functional status of participants was evaluated through activities of daily living (ADL) and instrumental activities of daily living (IADL). Logistic regression analyses were employed to investigate variables associated with LUTS/BPH. RESULTS Univariate logistic regression revealed associations between loneliness (OR: 1.26; 95 % CI: 1.08-1.46) (excluding social isolation), ADL (OR: 2.17; 95 % CI: 1.86-2.52), IADL disability (OR: 1.37; 95 % CI: 1.16-1.60), and LUTS/BPH. Following rigorous adjustment for potential confounding factors, it was determined that ADL disability independently correlated with LUTS/BPH (OR: 1.92; 95 % CI: 1.17-3.17). CONCLUSION ADL disability is significantly linked to an elevated risk of LUTS/BPH in Chinese elderly men. These findings enhance our understanding of the relationship between functional status and LUTS/BPH.

Abstract
OBJECTIVE Benign prostatic hyperplasia (BPH) management has evolved from transurethral resection of the prostate (TURP) to holmium laser enucleation of the prostate (HoLEP). Recent innovation introduces Moses™ technology in holmium lasers, with the Lumenis Pulse™ system. METHODS To compare Moses-augmented HoLEP (MoLEP) to non-Moses HoLEP in terms of enucleation efficiency, hemostasis, and applicability in day surgery settings. A single-blind, prospective, parallel randomized controlled trial was conducted in Shanghai, China, from March to December 2022. Ethical approval (SK2020-038) was obtained, and 100 consenting men over 50 with BPH indications were randomized (1:1) into MoLEP and HoLEP groups. Surgical procedures were standardized, and outcomes were assessed by blinded analysts. RESULTS Data from 80 participants (38 MoLEP, 42 HoLEP) were analyzed. Baseline characteristics were comparable. MoLEP demonstrated superior enucleation efficiency (3.5±0.8 g/min) and shorter enucleation time (22.5±7.6 minutes) compared to HoLEP, although not statistically significant. MoLEP achieved hemostasis in less time (6.6±4.2 minutes) than HoLEP (11.2±5.1 minutes). Postoperative care demands varied, with MoLEP requiring less bladder irrigation. MoLEP exhibited a shorter average catheterization time (1.3±0.1 days) and reduced hospitalization compared to HoLEP. Both groups showed significant postoperative improvements in functional outcomes. CONCLUSION While statistical significance was not achieved in certain outcome measures, MoLEP exhibited potential advantages in postoperative care demands, shorter catheterization time, and reduced hospitalization, suggesting its feasibility and safety in day surgery settings. Postoperative functional outcomes improved significantly in both groups.

Comparative efficacy of commercial oral poly-herbal traditional Chinese medicine formulations combined with western medicine in benign prostatic hyperplasia management: a systematic review and network meta-analysis. Front Pharmacol 2024; 15:1358340. [PMID: 38904002 PMCID: PMC11187581 DOI: 10.3389/fphar.2024.1358340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 05/03/2024] [Indexed: 06/22/2024] Open
Abstract
Background: Benign prostatic hyperplasia (BPH) is prevalent among the aging male population and often presents with distressing lower urinary tract symptoms. There is emerging evidence that commercial oral poly-herbal traditional Chinese medicine (TCM) formulation combined with Western medicine (WM) may offer enhanced therapeutic effects compared to WM alone in BPH treatment. Nevertheless, determining the optimal formulations for BPH remains controversial. We aimed to employ a network meta-analysis to compare and assess differences among commonly used and recommended poly-herbal TCM formulations outlined in the Chinese guidelines for BPH treatment, providing clinical medication recommendations and guidance. Methods: We extensively searched for RCTs of BPH patients that had oral poly-herbal TCM formulations and WM treatment, covering both English and Chinese databases up to 31 October 2023. The quality of the included studies was evaluated using the Cochrane risk-of-bias tool Version 2 (ROB2). A Bayesian network meta-analysis was performed to assess the effectiveness of various formulations, followed by sensitivity and subgroup analyses. Results: Our meta-analysis included 107 RCTs involving 11,037 patients across 16 oral poly-herbal TCM formulations. The quality of the selected studies was assessed as "Some concerns". Most formulations combined with WM demonstrated superior therapeutic efficacy compared to WM alone. For clinical effective rate, Jingui Shenqi pill (JGSQ) + WM had the highest-ranking probability (87.38%). Concerning International Prostate Symptom Score (IPSS) and maximum flow rate of urine, Guizhi Fuling capsule (GZFL) + WM was most effective (91.10% and 98.55%). Regarding the quality of life score and postvoid residual urine, Pulean tablet (PLA) + WM ranked first (86.71% and 91.81%). In controlling prostate volume, Huange capsule (HE) + WM demonstrated the highest efficacy (95.65%). Additionally, among the interventions, Lingze (LZ) + WM capsule exhibited the lowest incidence of adverse drug reactions (2.32%). Conclusion: Combining oral poly-herbal TCM formulations with WM may provide greater therapeutic benefits in BPH treatment compared to WM alone. JGSQ, GZFL, PLA, and HE emerged as promising treatment options. However, further rigorous empirical studies are essential to substantiate these findings.

Salvia miltiorrhiza Bunge Ameliorates Benign Prostatic Hyperplasia through Regulation of Oxidative Stress via Nrf-2/HO-1 Activation. J Microbiol Biotechnol 2024; 34:1059-1072. [PMID: 37994101 PMCID: PMC11180924 DOI: 10.4014/jmb.2308.08053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 09/27/2023] [Accepted: 10/23/2023] [Indexed: 11/24/2023]
Abstract
Oxidative stress is a key factor in the pathogenesis of benign prostatic hyperplasia (BPH) that leads to inflammation. This study aimed to evaluate the ameliorative effects of Salvia miltiorrhiza Bunge extract (HLT-101) on BPH through the regulation of oxidative stress and inflammation. A testosterone propionate (TP)-induced BPH rat model was orally administered HLT-101 (20, 40, or 80 mg/kg), and its effects on oxidative stress- and inflammation-related gene expression were examined. Further, HLT-101 was assessed for its effect on reactive oxygen species (ROS) levels and Nrf-2/HO-1 signaling pathways in BPH-1 cells. HLT-101 decreased testosterone-induced excessive free radical production and inflammatory factor activation. Moreover, HLT-101 treatment significantly decreased the intracellular ROS level in the TNF-α and IFN-γ treated BPH-1 cells through the activation of Nrf-2. In addition, HLT-101 treatment inhibited the NF-κB pathway and androgen receptor (AR) signaling, which is highly linked to the pathogenesis of BPH. Therefore, HLT-101 has the potential to be an effective treatment reagent for BPH because of its ability to reduce inflammation and oxidative stress via Nrf-2/HO-1 signaling.

Abstract
The prostate undergoes normal or pathological morphological changes throughout life. An understanding of these changes is fundamental for the comprehension of aging-related pathological processes such as benign prostatic hyperplasia (BPH) and cancer. In the present study, we show some of these morphological changes, as well as histochemical techniques like Weigert's resorcin-fuchsin method, Picrosirius Red, and Gömöri's reticulin for use as tools in the study of prostate tissue under light microscopy. For this purpose, prostates of the Mongolian gerbil (n = 9), an experimental model that develops BPH spontaneously, were analyzed at three life stages: young (1 month old), adult (3 months old), and old (15 months old). The results showed that fibrillar components such as collagen, and reticular and elastic fibers, change throughout life. In young animals, the prostate has cuboidal epithelium surrounded by thin layers of smooth muscle, continuous collagen fibers, winding reticular fibers, and sporadic elastic fibers. With adulthood, the epithelium becomes columnar, encircled by compacted muscle cells among slender collagen fibers, elongated reticular fibers, and linear elastic fibers. In aging individuals, the prostate's epithelium stratifies, surrounded by thick muscle layers among dense collagen fibers, disordered reticular fibers, and elastic fibers in different planes. We also identified a few accumulations of lipid droplets and lipofuscin granules in adult animals and high accumulation in old animals evidenced by Oil red O and Gömöri-Halmi techniques, respectively. The histochemical techniques presented here have been demonstrated to be useful and accessible tools in prostate studies. RESEARCH HIGHLIGHTS: Cytochemical techniques to study prostate morphology. The prostate changes with age.

Abstract
Benign prostatic hyperplasia (BPH) is the non-malignant enlargement of the prostate, associated with lower urinary tract symptoms (LUTSs). Taraxaci Herba (TH), commonly known as dandelion, has traditionally been utilized in East Asia to treat symptoms related to LUTSs. Based on this traditional use, our study aimed to explore the inhibitory effects of TH on BPH progression using a testosterone propionate-induced rat model. To induce BPH, male Sprague Dawley rats were castrated and injected subcutaneously with testosterone propionate (3 mg/kg/day) for 28 days. Concurrently, TH extract was administered orally at doses of 100 and 300 mg/kg/day throughout the four-week period of testosterone propionate injections. The TH extract significantly reduced both the absolute and relative weights of the prostate, along with histopathological changes in the gland. Moreover, it lowered serum levels of testosterone and dihydrotestosterone and reduced the expression of the androgen receptor in the prostate. Additionally, the TH extract modulated the protein expressions of Bax and Bcl-2, which are key regulators of apoptosis in prostate cells. Collectively, our findings suggest that TH inhibits BPH development partially by modulating androgen signaling and inducing apoptosis within the prostate.

Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) is the most common urologic disease in aging males, affecting 50% of men over 50 and up to 80% of men over 80 years old. Its negative impact on health-related quality of life implores further investigation into its risk factors and strategies for effective management. Although the exact molecular mechanisms underlying pathophysiological onset of BPH are poorly defined, the current hypothesized contributors to BPH and lower urinary tract symptoms (LUTS) include aging, inflammation, metabolic syndrome, and hormonal changes. These processes are indirectly influenced by circadian rhythm disruption. In this article, we review the recent evidence on the potential association of light changes/circadian rhythm disruption and the onset of BPH and impact on treatment. METHODS A narrative literature review was conducted using PubMed and Google Scholar to identify supporting evidence. The articles referenced ranged from 1975 to 2023. RESULTS A clear relationship between BPH/LUTS and circadian rhythm disruption is yet to be established. However, common mediators influence both diseases, including proinflammatory states, metabolic syndrome, and hormonal regulation that can be asserted to circadian disruption. Some studies have identified a possible relationship between general LUTS and sleep disturbance, but little research has been done on the medical management of these diseases and how circadian rhythm disruption further affects treatment outcomes. CONCLUSIONS There is evidence to implicate a relationship between BPH/LUTS and circadian rhythm disruptions. However, there is scarce literature on potential specific link in medical management of the disease and treatment outcomes with circadian rhythm disruption. Further study is warranted to provide BPH patients with insights into circadian rhythm directed appropriate interventions.

Abstract
The prostate is a vital accessory gonad in the mammalian male reproductive system. With the ever-increasing proportion of the population over 60 years of age worldwide, the incidence of prostate diseases, such as benign prostatic hyperplasia (BPH) and prostate cancer (PCa), is on the rise and is gradually becoming a significant medical problem globally. The notch signaling pathway is essential in regulating prostate early development. However, the potential regulatory mechanism of Notch signaling in prostatic enlargement and hyperplasia remains unclear. In this study, we proved that overactivation of Notch1 signaling in mouse prostatic epithelial cells (OEx) led to prostatic enlargement via enhancing proliferation and inhibiting apoptosis of prostatic epithelial cells. Further study showed that N1ICD/RBPJ directly up-regulated the androgen receptor (AR) and enhanced prostatic sensitivity to androgens. Hyper-proliferation was not found in orchidectomized OEx mice without androgen supply but was observed after Dihydrotestosterone (DHT) supplementation. Our data showed that the number of mitochondrion in prostatic epithelial cells of OEx mice was increased, but the mitochondrial function was impaired, and the essential activity of the mitochondrial respiratory electron transport chain was significantly weakened. Disordered mitochondrial number and metabolic function further resulted in excessive accumulation of reactive oxygen species (ROS). Importantly, anti-oxidant N-Acetyl-L-Cysteine (NAC) therapy could alleviate prostatic hyperplasia caused by the over-activation of Notch1 signaling. Furthermore, we observed the incremental Notch signaling activity in progenitor-like club cells in the scRNA-seq data set of human BPH patients. Moreover, the increased number of TROP2+ progenitors and Club cells was also confirmed in our OEx mice. In conclusion, our study revealed that over-activated Notch1 signaling induces prostatic enlargement by increasing androgen receptor sensitivity, disrupting cellular mitochondrial metabolism, increasing ROS, and a higher number of progenitor cells, all of which can be effectively rescued by NAC treatment.

Post-Voided Residual Ratio Does Not Predict Trifecta Outcome after Transurethral Resection of Prostate. Life (Basel) 2024; 14:445. [PMID: 38672716 PMCID: PMC11051523 DOI: 10.3390/life14040445] [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: 01/31/2024] [Revised: 03/25/2024] [Accepted: 03/25/2024] [Indexed: 04/28/2024] Open
Abstract
The purpose of this study was to assess the importance of the post-void residual (PVR) ratio (PVR ratio) in achieving a favorable trifecta outcome for patients suffering from lower urinary tract symptoms and benign prostatic enlargement (LUTS-BPE) who undergo transurethral resection of the prostate (TURP). Starting from 2015, a series of patients with LUTS-BPE who underwent TURP were included in a forward-looking study. These patients were assessed using the international prostate symptom score (IPSS) screening tool, uroflowmetry, and a transrectal ultrasound to measure prostate volume (TRUS). Both the PVR urine volume and the PVR ratio (PVR-R), which is the PVR as a percentage of total bladder volume (voided volume + PVR), were measured. The assessment of outcomes was based on the trifecta favorable outcome, defined as meeting all of the following criteria: (1) absence of perioperative complications, (2) a postoperative IPSS of less than eight, and (3) a postoperative maximum urinary flow rate (Qmax) greater than 15 mL/s. A total of 143 patients were included, with a median age of 70 years (interquartile range 65-73). Of these, 58% (83/143) achieved a positive trifecta outcome. Upon conducting a multivariate analysis, both IPSS and Qmax were identified as predictors of a positive trifecta outcome, whereas the PVR-R did not prove to be an independent predictor. In summary, it was found that preoperative IPSS and Qmax are indicative of a trifecta outcome following TURP, whereas PVR-R is not.

YAP-mediated GPER signaling impedes proliferation and survival of prostate epithelium in benign prostatic hyperplasia. iScience 2024; 27:109125.

Abstract
Benign prostatic hyperplasia (BPH) occurs when there is an imbalance between the proliferation and death of prostate cells, which is regulated tightly by estrogen signaling. However, the role of G protein-coupled estrogen receptor (GPER) in prostate cell survival remains ambiguous. In this study, we observed that prostates with epithelial hyperplasia showed increased yes-associated protein 1 (YAP) expression and decreased levels of estrogen and GPER. Blocking YAP through genetic or drug interventions led to reduced proliferation and increased apoptosis in the prostate epithelial cells. Interestingly, GPER agonists produced similar effects. GPER activation enhanced the phosphorylation and degradation of YAP, which was crucial for suppressing cell proliferation and survival. The Gαs/cAMP/PKA/LATS pathway, downstream of GPER, transmitted signals that facilitated YAP inhibition. This study investigated the interaction between GPER and YAP in the prostate epithelial cells and its contribution to BPH development. It lays the groundwork for future research on developing BPH treatments.

Abstract
PURPOSE Adreno-muscarinic synergy, a supra-additional contractile response to simultaneous application of α-adrenoreceptor and muscarinic receptor agonists, is a feature of several lower urinary tract regions that have dual sympathetic and parasympathetic innervation. We tested the hypothesis that synergy is also a feature of prostate tissue obtained from men with benign prostatic enlargement. METHODS Isolated tissue strips were dissected from prostate 'chips', collected after transurethral prostate resection procedures for in vitro experiments, to measure isometric tension at 36°C. RESULTS Added separately to the superfusate, phenylephrine and carbachol generated contractions with mean pEC50 (-log10EC50) values of 5.36 and 5.58, respectively, although phenylephrine maximal responses were about six-fold greater. In the presence of carbachol, the mean phenylephrine pEC50 was significantly increased to 5.84 and maximal response increased by 28%; overall, a significant synergistic response was demonstrated. The synergistic response was reduced by muscarinic receptor antagonists, most potently by the M3-selective agent 4-DAMP (1,1-dimethyl-4-diphenylacetoxypiperidinium iodide), and less so by M2 and M1-selective inhibitors gallamine and pirenzepine, but with an overall profile indicating M3/M2 mediation of the synergistic response. The magnitude of the synergistic response was variable between prostate chips that provided isolated preparations suggesting regional heterogenicity, although their zonal origin could not be determined. CONCLUSION These experiments show that adreno-muscarinic contractile synergy is a feature of human hyperplastic prostate tissue. This has implications for the use of a combination therapy of α-blockers and anti-muscarinic agent to relieve secondary symptoms associated with benign prostatic hyperplasia, at least in men who can tolerate antimuscarinics without a risk of retention.

Abstract
The prevalence of benign prostatic hyperplasia (BPH) and its associated lower urinary tract symptoms (LUTS) increases with age. Considering that BPH drug treatment is associated with complications, this study aimed to investigate the effects of L-carnitine (LC) and Coenzyme Q10 (CoQ10) supplementation as an adjunct therapy to finasteride in the management of LUTS in older men affected with BPH. Fifty eligible volunteers (25 per group) were randomly assigned to either intervention (finasteride + LC and CoQ10 supplements) or control (finasteride + placebo) groups. International prostate symptom score (IPSS), international index of erectile function (IIEF), quality of life index (QoL), as well as serum levels of Prostate-specific antigen (PSA), were assessed. Prostate ultrasound evaluation was also performed, before and after 8 wk of intervention. Supplementation with LC and CoQ10 led to a significant decrease in prostate volume (p < 0.001) as well as a significant increase in IIEF (p < 0.001), compared to the control group. However, there were no significant between-group differences in IPSS (p = 0.503), QoL scores (p = 0.339), and PSA levels (p = 0.482). CoQ10 and LC supplements might be beneficial in combination with standard therapies in the management of BPH and its related complications.

[PMID: 37796326 PMCID: PMC10789837 DOI: 10.1007/s00261-023-04050-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Revised: 04/30/2023] [Accepted: 05/02/2023] [Indexed: 10/06/2023]
Abstract
PURPOSE To construct machine learning models based on radiomics features combing conventional transrectal ultrasound (B-mode) and contrast-enhanced ultrasound (CEUS) to improve prostate cancer (PCa) detection in peripheral zone (PZ). METHODS A prospective study of 166 men (72 benign, 94 malignant lesions) with targeted biopsy-confirmed pathology who underwent B-mode and CEUS examinations was performed. Risk factors, including age, serum total prostate-specific antigen (tPSA), free PSA (fPSA), f/t PSA, prostate volume and prostate-specific antigen density (PSAD), were collected. Time-intensity curves were obtained using SonoLiver software for all lesions in regions of interest. Four parameters were collected as risk factors: the maximum intensity (IMAX), rise time (RT), time to peak (TTP), and mean transit time (MTT). Radiomics features were extracted from the target lesions from B-mode and CEUS imaging. Multivariable logistic regression analysis was used to construct the model. RESULTS A total of 3306 features were extracted from seven categories. Finally, 32 features were screened out from radiomics models. Five models were developed to predict PCa: the B-mode radiomics model (B model), CEUS radiomics model (CEUS model), B-CEUS combined radiomics model (B-CEUS model), risk factors model, and risk factors-radiomics combined model (combined model). Age, PSAD, tPSA, and RT were significant independent predictors in discriminating benign and malignant PZ lesions (P < 0.05). The risk factors model combing these four predictors showed better discrimination in the validation cohort (area under the curve [AUC], 0.84) than the radiomics images (AUC, 0.79 on B model; AUC, 0.78 on CEUS model; AUC, 0.83 on B-CEUS model), and the combined model (AUC: 0.89) achieved the greatest predictive efficacy. CONCLUSION The prediction model including B-mode and CEUS radiomics signatures and risk factors represents a promising diagnostic tool for PCa detection in PZ, which may contribute to clinical decision-making.

Abstract
INTRODUCTION A positive association between benign prostate hyperplasia (BPH)/lower urinary tract symptoms (LUTS) and metabolic syndrome (MetS) was reported in several studies, but studies from Asia often showed conflicting results. MATERIALS AND METHODS Medical records were obtained from a health promotion center database between 2021 and 2022. Men without a history of treatment for LUTS were evaluated using the International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), transrectal ultrasonography. RESULTS Of 1345 individuals, 603 (44.8%) had MetS. Older age, higher IPSS values, higher prevalence rates of BPH and overactive bladder, higher triiodothyronine, and lower testosterone and sex-hormone binding globulin were observed in individuals with MetS than in individuals without MetS. The severity of LUTS significantly increased in the individuals with MetS (p = .002). In individuals with MetS, age, HbA1c, and cerebrovascular disease (CVD) were associated with IPSS. For OABSS, age, HbA1c, thyroid-stimulating hormone (TSH), coronary artery occlusive disease, and CVD were identified as predictors. CONCLUSIONS We confirmed the positive correlation between MetS and BPH/LUTS in Korean. Factors including TSH and atherosclerosis affected LUTS in individuals with MetS. These findings suggested a potential role of thyroid hormones and atherosclerosis in the etiology and treatment of BPH/LUTS in patients with MetS.

[PMID: 37866805 DOI: 10.1016/j.lfs.2023.122190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 10/12/2023] [Accepted: 10/16/2023] [Indexed: 10/24/2023]
Abstract
BACKGROUND The search for alternative therapies for treatment of Benign prostatic hyperplasia (BPH) has been increasingly studied to avoid the common adverse effects of the usual regimens. Therefore, this study aimed at delineating possible mechanisms of benign prostatic hyperplasia (BPH) and possible therapeutic role of zinc oxide nanoparticles (ZnO-NPs) versus vanillic acid. METHODS Forty rats were divided into five groups: control, sham control, Testosterone-induced BPH, BPH and Zn-NPs, and BPH and vanillic acid. Light microscopic, immune-histochemical; PCNA, Bcl-2, Bax, caspase-3, p-Akt and p-mTOR, histomorphometric analysis, MDA/SOD and GPx and were done. Gene expression of p-Akt, p-mTOR and survivin were evaluated. RESULTS Application of zinc oxide nanoparticles as well as vanillic acid significantly reduced prostatic index, epithelial thickness, stromal collagen fibers, expression of PCNA, Bcl2, p-Akt, p-mTOR and MDA tissue level (p < 0.05). Whereas expression of Bax and caspase 3, and tissue levels of SOD and GPx were significantly increased in groups treated with Zno-Nps and vanillic acid compared to that of BPH group. Zinc oxide nanoparticles showed a better effect than vanillic acid in alleviating BPH. CONCLUSION These findings suggested that ZnO-NPs as well as VA ameliorated the histolo-pathological and biochemical effects of induced BPH, moreover they improved the proapoptotic and antioxidant parameters which ere induced in BPH. It is recommended to search for new agents to prevent the development and progression of BPH.

Abstract
PURPOSE OF REVIEW Benign prostatic hyperplasia (BPH) is a disease of the lower urinary tract which often requires surgical treatment. Recently, there has been a deluge of new treatment options, rarely validated or compared to current treatments on a benchtop model. The purpose of this review is to examine the literature and report which benchtop models are currently being used, which therapies have been tested on them, and what outcomes are being studied on each model. RECENT FINDINGS There are various benchtop models to choose from, each with their unique benefits and drawbacks. Perfused porcine kidney models are used to assess bleeding on the benchtop, ex-vivo human prostate helps to see specific interactions of devices with the prostatic tissue, and all other models have evaluated tissue ablation rates and depth of coagulation. There are currently no synthetic or non-animal tissues being used for this purpose, and surgical techniques such as enucleation, water-jet ablation, prostate stents, and water vapor thermal therapy have no representation in these benchtop tests. Benchtop testing serves an important role in the evaluation and comparison of surgical treatments for BPH. This testing allows these therapies to be objectively compared to one another, helping novel medical devices in their path to market and urologists make treatment decisions. Future directions may include further validation of the animal models currently being used and development of synthetic models which mimic the prostate on the benchtop.

Abstract
OBJECTIVE We aimed to explore the long-term outcomes of bipolar transurethral enucleation and resection of the prostate (B-TUERP) in patients with benign prostatic hyperplasia (BPH). METHODS A total of 1195 patients with BPH who underwent B-TUERP from July 2006 to June 2010 were enrolled in this retrospective study. Preoperative data, particularly urodynamic study (UDS) parameters, were collected by questionnaire and examination. Postoperative follow-up was performed at 3, 6, 12, 36, 60 and 120 months, respectively. Demographic, perioperative and functional data were analysed. International Prostate Symptom Score, quality of life and overactive bladder syndrome score (OABSS) were used to assess the functional scores. Predictors of postoperative urgency incontinence were identified by univariate analysis. RESULTS Long-term outcomes of functional score were significantly better than the preoperative values. All UDS variables, including maximum urinary flow rate, postvoid residual urine volume, compliance, maximum cystometric capacity (MCC), bladder outlet obstruction index, prostatic urethral pressure and detrusor pressure at maximum urinary flow rate, were all significantly improved. No one required reoperation due to recurrent BPH. The postoperative rate of transient urinary incontinence was 31.7%, while the long-term incontinence rate was 0%. Retrograde ejaculation occurred in 44.3% patients who remained sexually active after operation. Patients who had transient urge incontinence were older with preoperative higher OABSS, prostate-specific antigen (PSA) and detrusor overactivity rate and lower MCC. CONCLUSION B-TUERP is a safe, successful and highly effective treatment for BPH at 10-year follow-up. Increased age, OABSS, PSA level and detrusor overactivity rate are potential predictors for urge incontinence after B-TUERP.

Abstract
Benign prostatic hyperplasia (BPH) is an age-related enlargement of the prostate with urethral obstruction that predominantly affects the middle-aged and older male population, resulting in disruptive lower urinary tract symptoms (LUTS), thus creating a profound impact on an individual's quality of life. The development of LUTS may be linked to overexpression of oxytocin receptors (OXTR), resulting in increased baseline myogenic tone within the prostate. Thus, it is hypothesised that targeting OXTR using oxytocin receptor antagonists (atosiban, cligosiban, and β-Mercapto-β,β-cyclopentamethylenepropionyl1, O-Me-Tyr2, Orn8]-Oxytocin (ßMßßC)), may attenuate myogenic tone within the prostate. Organ bath and immunohistochemistry techniques were conducted on prostate tissue from young and older rats. Our contractility studies demonstrated that atosiban significantly decreased the frequency of spontaneous contractions within the prostate of young rats (**** p < 0.0001), and cligosiban (* p < 0.05), and ßMßßC (**** p < 0.0001) in older rats. Additionally, immunohistochemistry findings revealed that nuclear-specific OXTR was predominantly expressed within the epithelium of the prostate of both young (*** p < 0.001) and older rats (**** p < 0.0001). In conclusion, our findings indicate that oxytocin is a key modulator of prostate contractility, and targeting OXTR is a promising avenue in the development of novel BPH drugs.

Abstract
BACKGROUND With an increasing reliance on online sources for medical information, we studied the quality and completeness of health literacy videos on TikTok regarding BPH. METHODS A cross-sectional systematic evaluation of TikTok videos using the search term "Benign Prostatic Hyperplasia" was performed on 14th April 2023, and included 49 patient information and educational videos. The videos were then analysed by two reviewers and scored using two instruments: the DISCERN instrument and a completeness analysis. RESULTS Of the 49 videos, 38 were created by healthcare professionals (HCPs). The average length of each video was 62.7 ± 59.3 s, with a large average number of total views (24,990.1 ± 109,534.9 views). The DISCERN score trended higher in every category in videos published by HCPs compared to non-HCPs, with HCPs providing a statistically significant increase in reliability (19.0,14.6, p < 0.05) and total score (29.4,23, p < 0.05). Majority of videos were deemed as poor or worse (91.8%) in quality. The completeness of the videos' content was also evaluated across five categories with an average score of 2.53 ± 2.1 out of the maximum 12. The DISCERN scores did not correlate with the degree of completeness of the videos (r = 0.226). CONCLUSION BPH videos on TikTok have a wide reach, but the videos are mostly of low quality and completeness. Future videos should be made with quality and completeness in mind given the large viewership and more can be done to evaluate the extent of BPH misinformation and its impact on patients.

Abstract
This study investigated the effect of Urtica dioica roots etheric extract (UDEE) on oxidative stress, and urine obstruction with histopathological examinations of prostatic and renal tissues,and suggests computational methods as a complementary method, to make a hypothesis on the overall effect of UDEE in the treatment of benign prostatic hyperplasia (BPH).Gas chromatography/mass spectrometry was utilised to characterise UDEE.BPH was induced in rats through daily subcutaneous injections of testosterone propionate. Rats were also orally administered UDEE or a vehicle. After four weeks, prostate weight, urine output, and biochemical markers were evaluated. UDEE treatment demonstrated significant regression of prostatic enlargement, improved biochemical and histopathological characteristics, and regulation of antioxidant activity levels. Phytosteroids stand out, act by inhibiting 5α-reductase and aromatase. This study provides an insight into treatment of BPH, demonstrating safety of this compound towards the kidney compared to finasteride without severe side effects.

Abstract
BACKGROUND Recent studies identified several risk factors of benign prostatic hyperplasia (BPH), including dyslipidemia, type 2 diabetes mellitus, hypertension, and obesity. But they were not so reliable and some studies contradicted with one another. Hence, a reliable method is urgently needed to explore exact factors that facilitated BPH development. METHODS The study was based on Mendelian randomization (MR) design. All participants were from the most recent genome-wide association studies (GWAS) with large sample size. The causal associations between nine phenotypes (total testosterone level, bioavailable testosterone level, sex hormone-binding globulin, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, type 2 diabetes mellitus, hyper-tension, and body mass index) and BPH outcome were estimated. Two sample MR, bidirectional MR, and multivariate MR (MVMR) were performed. RESULTS Increase in bioavailable testosterone level was able to induce BPH based on nearly all combination methods [beta (95% confidence interval (CI)): 0.20 (0.06-0.34) for inverse variance weighted (IVW)]. The other traits seemed to interact with testosterone level and did not cause BPH generally. Higher triglycerides level was likely to raise bioavailable testosterone level [beta (95% CI): 0.04 (0.01-0.06) for IVW]. In MVMR model, bioavailable testosterone level was still associated with BPH occurrence [beta (95% CI) 0.27 (0.03-0.50) for IVW]. CONCLUSIONS We for the first time validated the central role of bioavailable testosterone level in the pathogenesis of BPH. The complex associations between other traits and BPH should be further investigated.

Abstract
Phthalates are a family of aromatic chemical compounds mainly used as plasticizers. Among phthalates, di-n-butyl phthalate (DBP) is a low-molecular-weight phthalate used as a component of many cosmetic products, such as nail polish, and other perfumed personal care products. DBP has toxic effects on reproductive health, inducing testicular damage and developmental malformations. Inside the male reproductive system, the prostate gland reacts to both male and female sex steroids. For this reason, it represents an important target of endocrine-disrupting chemicals (EDCs), compounds that are able to affect the estrogen and androgen signaling pathways, thus interfering with prostate homeostasis and inducing several prostate pathologies. The aim of this project was to investigate the effects of DBP, alone and in combination with testosterone (T), 17β-estradiol (E2), and both, on the normal PNT1A human prostate cell-derived cell line, to mimic environmental contamination. We showed that DBP and all of the tested mixtures increase cell viability through activation of both estrogen receptor α (ERα) and androgen receptor (AR). DBP modulated steroid receptor levels in a nonmonotonic way, and differently to endogenous hormones. In addition, DBP translocated ERα to the nucleus over different durations and for a more prolonged time than E2, altering the normal responsiveness of prostate cells. However, DBP alone seemed not to influence AR localization, but AR was continuously and persistently activated when DBP was used in combination. Our results show that DBP alone, and in mixture, alters redox homeostasis in prostate cells, leading to a greater increase in cell oxidative susceptibility. In addition, we also demonstrate that DBP increases the migratory potential of PNT1A cells. In conclusion, our findings demonstrate that DBP, alone and in mixtures with endogenous steroid hormones, acts as an EDC, resulting in an altered prostate cell physiology and making these cells more prone to cancer transformation.

Mechanism of Androgen-Independent Stromal Proliferation in Benign Prostatic Hyperplasia. Int J Mol Sci 2023; 24:11634. [PMID: 37511400 PMCID: PMC10380833 DOI: 10.3390/ijms241411634] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 07/14/2023] [Accepted: 07/16/2023] [Indexed: 07/30/2023] Open
Abstract
Benign prostatic hyperplasia (BPH) is a chronic proliferative disease showing stromal-dominant proliferation. However, the detailed proliferation mechanism has remained unclear. Although aging and androgen have been reported as definitive risk factors for BPH, recent studies have focused on the involvement of androgen-independent factors. Androgen-independent factors include ischemia, oxidative stress, metabolic syndrome, infection, autoimmune reactions, and inflammation, with inflammation in BPH tissues playing a central role in the BPH proliferative process. Inflammation in BPH tissues by various factors finally leads to tissue remodeling and stromal proliferation through the wound healing process of the prostate. To elucidate the proliferative mechanism of BPH, a study using whole-genome gene expression analysis in a stromal-dominant BPH rat model was performed and showed that immune response-related pathways and complement classical pathways are activated. Furthermore, expression analysis using this BPH rat model showed that the autoimmune reaction triggered complement pathway activation in the proliferative process of BPH. BPH is a multifactorial disease, and understanding the role of androgen-independent factors including immune responses contributes to elucidating the pathogenesis of BPH. Androgen-independent factors may lead to new therapeutic targets for BPH, and further development of this research is expected.

Abstract
Benign prostatic hyperplasia (BPH) is a common urological disease affecting aging men. Its pathogenesis is regarded as complex and multifactorial, with sex hormones and inflammation as key contributory factors. In the current study, we investigated the anti-BPH potential of terpenoids present in the fruits of Sorbus intermedia (EHRH.) PERS. Not only the effects on testosterone-stimulated normal prostate epithelial PNT2 cells, namely suppression of 5-α-reductase activity, PSA secretion, and cell proliferation, were determined but also the inhibitory activity on heat-induced protein denaturation, hyaluronidase, as well as IL-6, TNF-α, and NO release in LPS-treated macrophages. Sorbus terpenoids significantly inhibited 5-α-reductase activity and reduced PSA secretion in PNT2 cells, reversing the stimulatory effect of testosterone. PNT2 cell proliferation was also found to be attenuated. Subsequently, all compounds reduced the release of pro-inflammatory mediators in RAW 264.7 cells. In addition, ursolic acid (UA) and its aldehyde (UAL) were the most potent hyaluronidase inhibitors of all compounds, with IC50 values of 225.75 µg/mL and 369.77 µg/mL, respectively. For better understanding and interpretation of the overall effect of Sorbus terpenoids on different aspects of BPH pathogenesis and development, cluster analysis was applied.

Abstract
Benign prostatic hypertrophy (BPH) is a noncancerous enlargement of the prostate gland that develops from hyper-proliferation of the stromal and epithelium region. Activation of pathways involving inflammation and oxidative stress can contribute to cell proliferation in BPH and tumorigenesis. Agricultural-waste-derived extracts have drawn the attention of researchers as they represent a valid and sustainable way to exploit waste production. Indeed, such extracts are rich in bioactive compounds and can provide health-promoting effects. In particular, extracts obtained from pomegranate wastes and by-products have been shown to exert antioxidant and anti-inflammatory effects. This study focused on the evaluation of the anti-angiogenic effects and chemopreventive action of a pomegranate extract (PWE) in cellular models of BPH. In our experimental conditions, we observed that PWE was able to significantly (p < 0.001) reduce the proliferation and migration rates (up to 60%), together with the clonogenic capacity of BPH-1 cells concomitantly with the reduction in inflammatory cytokines (e.g., IL-6, PGE2) and pro-angiogenic factor (VEGF-ADMA) release. Additionally, we demonstrated the ability of PWE in reducing angiogenesis in an in vitro model of BPH consisting in transferring BPH-1-cell-conditioned media to human endothelial H5V cells. Indeed, PWE was able to reduce tube formation in H5V cells through VEGF level reduction even at low concentrations. Overall, we confirmed that inhibition of angiogenesis may be an alternative therapeutic option to prevent neovascularization in prostate tissue with BPH and its transformation into malignant prostate cancer.

Abstract
Background COVID-19, a serious respiratory disease that has the potential to affect numerous organs, is a serious threat to the health of people around the world. The objective of this article is to investigate the potential biological targets and mechanisms by which SARS-CoV-2 affects benign prostatic hyperplasia (BPH) and related symptoms. Methods We downloaded the COVID-19 datasets (GSE157103 and GSE166253) and the BPH datasets (GSE7307 and GSE132714) from the Gene Expression Omnibus (GEO) database. In GSE157103 and GSE7307, differentially expressed genes (DEGs) were found using the "Limma" package, and the intersection was utilized to obtain common DEGs. Further analyses followed, including those using Protein-Protein Interaction (PPI), Gene Ontology (GO) function enrichment analysis, and the Kyoto Encyclopedia of Genes and Genomes (KEGG). Potential hub genes were screened using three machine learning methods, and they were later verified using GSE132714 and GSE166253. The CIBERSORT analysis and the identification of transcription factors, miRNAs, and drugs as candidates were among the subsequent analyses. Results We identified 97 common DEGs from GSE157103 and GSE7307. According to the GO and KEGG analyses, the primary gene enrichment pathways were immune-related pathways. Machine learning methods were used to identify five hub genes (BIRC5, DNAJC4, DTL, LILRB2, and NDC80). They had good diagnostic properties in the training sets and were validated in the validation sets. According to CIBERSORT analysis, hub genes were closely related to CD4 memory activated of T cells, T cells regulatory and NK cells activated. The top 10 drug candidates (lucanthone, phytoestrogens, etoposide, dasatinib, piroxicam, pyrvinium, rapamycin, niclosamide, genistein, and testosterone) will also be evaluated by the P value, which is expected to be helpful for the treatment of COVID-19-infected patients with BPH. Conclusion Our findings reveal common signaling pathways, possible biological targets, and promising small molecule drugs for BPH and COVID-19. This is crucial to understand the potential common pathogenic and susceptibility pathways between them.

Abstract
BACKGROUND The association between sleep quality and benign prostate hyperplasia (BPH) has rarely been studied. The aim of this study was to examine the relationship between sleep quality and BPH among middle-aged and older men in India. METHODS This study used data from men over 45 years old in Wave 1 (2017-2018) of the Longitudinal Aging Study in India (LASI). Benign prostate hyperplasia was self-reported, and sleep symptoms were assessed using five questions modified from the Jenkins Sleep Scale. A total of 30,909 male participants were finally included. Multivariate logistic regression analysis, subgroup analysis, and interaction tests were performed. RESULTS Total 453 (1.49%) men reported benign prostatic hyperplasia and have higher sleep quality score (9.25 ± 3.89 vs. 8.13 ± 3.46). The results revealed that the sleep quality score and risk of benign prostatic hyperplasia were significantly correlated after adjusting for all confounding factors (OR:1.057, 95% CI: 1.031-1.084, p < 0.001]. After dividing people into four groups based on the quartile of sleep quality scores, compared with the first quartile group, the third quartile group was 1.32 times, and the fourth quartile group was 1.615 times more likely to develop benign prostate hyperplasia. A significant interaction effect of alcohol consumption was observed. (p for interaction < 0.05). CONCLUSION Worse sleep quality was significantly associated with a higher incidence of benign prostatic hyperplasia among middle-aged and older Indian men. A further prospective study is needed to clarify this association and explore potential mechanisms.

Abstract
Objective The aim of the present study was to observe the effect of the stroma proportion in hyperplasia nodules on the clinical symptoms of benign prostatic hyperplasia (BPH) patients and to identify the different genes and pathways in prostatic hyperplasia nodules between patients with epithelial-dominated hyperplasia (EDH) and stromal-dominated hyperplasia (SDH) nodules. Methods Sixty-seven BPH patient samples underwent transurethral resection of the prostate (TURP) were collected and retrospectively analyzed. The differences in clinical parameters between the EDH and SDH groups were investigated. Collagen fiber percentage was assessed, and the correlation with clinical parameters was evaluated. mRNA sequencing in hyperplasia nodules of 8 BPH patients was performed, and differentially expressed genes (DEGs) between the EDH and SDH groups were screened. These DEGs were analyzed using GO, KEGG and PPI analysis. Results The results showed the IPSS was significantly higher in the SDH group than in the EDH group (p < 0.01). The collagen fiber percentage of BPH nodules was higher in the SDH group than in the EDH group (p < 0.05), and the collagen fiber percentage was positively correlated with the IPSS (r = 0.4058, p = 0.0007). A total of 172 DEGs were obtained, including 63 up-regulated genes and 109 down-regulated genes. GO and KEGG pathway enrichment analyses showed DEGs were mainly enriched in extracellular matrix structural constituents. The top 10 hub genes were associated to the components of extracellular matrix and fibrosis. Conclusion These results suggested that the symptoms of BPH patients with SDH nodules may be associated with prostate fibrosis and fibrosis may be a significant contributing factor in BPH/LUTS patients with SDH nodules.

Abstract
Benign prostatic hyperplasia (BPH) is a common male condition that impacts many men's quality of life by generating lower urinary tract symptoms (LUTS). In recent years, inflammation has become very common in the prostate, and BPH with inflammation has a higher International Prostate Symptom Score (IPSS) score and an enlarged prostate. Chronic inflammation leads to tissue damage and the release of pro-inflammatory cytokines, which play an important role in the pathogenesis of BPH. We will focus on current advancements in pro-inflammatory cytokines in BPH, as well as the future of pro-inflammatory cytokine research.

Efficacy, Efficiency, and Safety of En-bloc vs Three-lobe Enucleation of the Prostate: A Propensity Score-matched Analysis. Urology 2023:S0090-4295(23)00172-3. [PMID: 36828266 DOI: 10.1016/j.urology.2023.02.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 01/25/2023] [Accepted: 02/07/2023] [Indexed: 02/24/2023]
Abstract
OBJECTIVE To assess efficacy, efficiency, and safety in holmium laser enucleation of the prostate (HoLEP), we directly compared intraoperative performance, postoperative outcomes, and safety in the original 3-lobe enucleation technique with the more recent en-bloc method. As HoLEP is widely accepted as a size-independent method for surgical treatment of patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO), detailed understanding of its benefits is mandatory. METHODS We conducted a retrospective, propensity score-matched analysis of 1,396 men who underwent HoLEP for LUTS/BPO between 2017 and 2020. We included 606 patients in the final analysis (en-bloc n = 303; 3-lobe n = 303), who were matched for prostate size (50 cc), age, body mass index, and preoperative international prostate symptom score. Patients were then stratified by technique, and groups were compared for perioperative parameters, safety, and short-term functional outcomes. RESULTS While postoperative symptoms and urodynamic parameters improved irrespective of technique, we report significantly less adverse events (Clavien-Dindo classification ≥II vs <II) for patients receiving en-bloc enucleation. Additionally, en-bloc enucleation was more efficient, that is, less than half of total laser energy (kJ), twice shorter enucleation time, and surgical performance (g/kJ/min) significantly increased 4-fold with prostate volume, compared to 3-lobe enucleation. CONCLUSION While HoLEP in general is a safe and effective procedure, en-bloc enucleation techniques offer better surgical performance.

Abstract
To target benign prostatic hyperplasia (BPH) as a common urinary disease in old men, in the current study, the antiproliferative and apoptotic mechanism of SH-PRO, a mixture of Angelica gigas and Astragalus membranaceus (2:1), was evaluated in BPH-1 cells and rats with testosterone-induced BPH. Herein, SH-PRO significantly reduced the viability of BPH-1 cells and dihydrotestosterone (DHT)-treated RWPE-1 cells. Also, SH-PRO increased the sub-G1 population in BPH-1 cells and consistently attenuated the expression of pro-PARP, pro-caspase 3, Bcl2, FOXO3a, androgen receptor (AR), and prostate-specific antigen (PSA) in BPH-1 cells and DHT-treated RWPE-1 cells. Of note, SH-PRO generated reactive oxygen species (ROS) in BPH-1 cells, while ROS inhibitor N-acetyl-l-cysteine (NAC) disturbed the ability of SH-PRO to reduce the expression of pro-PARP, FOXO3a, catalase, SOD, and increase sub-G1 population in BPH-1 cells. Furthermore, oral treatment of SH-PRO significantly abrogated the weight of the prostate in testosterone-treated rats compared to BPH control with the reduced expression of AR, PSA, and DHT and lower plasma levels of DTH, bFGF, and EGF with no toxicity. Overall, these findings highlight the antiproliferative and apoptotic potential of SH-PRO via ROS-mediated activation of PARP and caspase 3 and inhibition of FOXO3a/AR/PSA signaling as a potent anti-BPH candidate.

Abstract
With aging, the incidence of age-related diseases increases. Hence, age-related diseases are inevitable. However, the mechanisms by which aging leads to the onset and progression of age-related diseases remain unclear. It has been reported that inflammation is closely associated with age-related diseases and that the cGAS-STING signaling pathway, which can sense the aberrant presence of cytosolic DNA during aging and induce an inflammatory response, is an important mediator of inflammation in age-related diseases. With a better understanding of the structure and molecular biology of the cGAS-STING signaling axis, numerous selective inhibitors and agonists targeting the cGAS-STING pathway in human age-related diseases have been developed to modulate inflammatory responses. Here, we provide a narrative review of the activity of the cGAS- STING pathway in age-related diseases and discuss its general mechanisms in the onset and progression of age-related diseases. In addition, we outline treatments targeting the cGAS-STING pathway, which may constitute a potential therapeutic alternative for age-related diseases.

Abstract
Inhibition of 5α-reductase (5αR), which blocks the conversion of testosterone to its active metabolite, dihydrotestosterone, has been shown to impact further prostate enlargement (benign prostatic hyperplasia, or BPH). Clinical trials of standardized lipidosterolic extracts of Serenoa repens (LSESr), also known as standardized extracts of saw palmetto, have demonstrated improvement in lower urinary tract symptoms (LUTS) and delayed progression of BPH. The aim of this preclinical study was to compare two standardized LSESr, a proprietary ultrahigh-pressure supercritical carbon dioxide extract of S. repens (UHP-sCESr) and the well-established hexanic extract of S. repens (HESr), for both 5αR inhibition activity and lipid profiles. UHP-sCESr and HESr had nearly identical inhibition curves and comparable IC50 values for 5αR-1 (9.25 ± 0.87 and 9.86 ± 0.11 μg/mL, respectively; p = 0.43) and 5αR-2 (7.47 ± 0.07 and 7.72 ± 0.05 μg/mL, respectively; p = 0.0544). UHP-sCESr and HESr also had comparable lipid profiles based on similar total fatty acid levels (87.7% and 91.5%, respectively), weight/weight comparisons of individual fatty acids, and individual fatty acid ratios to lauric acid. In addition, UHP-sCESr meets the standard set by the United States Pharmacopeia (USP) monograph for authenticity and purity for a supercritical carbon dioxide (SCCO2) extract of saw palmetto, whereas HESr meets the standard set by the European Medicines Agency (EMA) for a well-established medicinal product. In conclusion, based on enzyme inhibition curves and IC50 values, a standardized lipid profile is important to achieve comparable mechanisms of action for lipidosterolic extracts of saw palmetto. UHP-sCESr offers a comparable, standardized LSESr for men with LUTS/BPH in regions where the proprietary HESr is not available.

Abstract
Panax ginseng C.A. Meyer, a widely used traditional medicine in East Asia, shows many beneficial effects on immune function, male erectile dysfunction, cancer, excessive oxidants, and aging issues. However, its effect on benign prostatic hyperplasia (BPH) and its potential in the treatment of side effects related to finasteride (Fi), an FDA-approved drug for BPH, are less known. This study aimed to verify the therapeutic effects of a water extract of P. ginseng (PGWE) on BPH in testosterone propionate (TP)-induced BPH rats and TP-treated RWPE-1 human epithelial cells, and the inhibitory potential on the Fi-induced side effects is also explored. In the TP-induced BPH rat model, PGWE alleviated the pathological markers of BPH such as weight and epithelial thickness of the prostate, and the serum level of dihydrotestosterone. PGWE downregulated androgen-related BPH factors such as 5α-reductase 2 and androgen receptor. PGWE also showed prostatic cell apoptosis accompanied by increased expression of Bax and decreased expression of Bcl-xL and cleaved-caspase 3, respectively, in addition to increasing mitochondrial dynamics in both in vivo and in vitro BPH models. Notably, reduced sperm count, one of the serious side effects of Fi, in the epididymis of BPH rats was recovered with PGWE treatment, suggesting less toxicity to sperm development by PGWE. PGWE also protected against Fi-induced sperm loss when PGWE was administered in combination with Fi without compromising the therapeutic effects of Fi on BPH. Based on these findings, we propose that PGWE could be an alternative therapeutic agent for BPH.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2023; 249:114358.

Abstract
Bisphenol A (BPA) is commonly used to produce epoxy resins and polycarbonate plastics. BPA is an endocrine-disrupting chemical that is leaked from the polymer and absorbed into the body to disrupt the endocrine system. Although BPA may cause cytotoxicity in the prostate, a hormone-dependent reproductive organ, its underlying mechanism has not yet been elucidated. Here, we investigated the effects of BPA on cell proliferation, apoptosis, and the wound healing process using prostate epithelial cells (RWPE-1) and stromal cells (WPMY-1). Observations revealed that BPA induced G2/M cell cycle arrest in both cell types through the ATM-CHK1/CHK2-CDC25c-CDC2 signaling pathway, and the IC50 values were estimated to be 150 μM. Furthermore, BPA was found to induce caspase-dependent apoptosis through initiator (caspase-8 and -9) and executioner (caspase-3 and -7) caspase cascades. In addition, BPA interfered with the wound healing process through inhibition of MMP-2 and - 9 expression, accompanied by reductions in the binding activities of AP-1 as well as NF-κB motifs. Phosphorylation of MAPKs was associated with the BPA-mediated toxicity of prostate cells. These results suggest that BPA exhibits prostate toxicity by inhibiting cell proliferation, inducing apoptosis, and interfering with the wound healing process. Our study provided new insights into the precise molecular mechanisms of BPA-induced toxicity in human prostate cells.

Abstract
PURPOSE Benign prostatic hyperplasia (BPH) is a urogenital disorder that affects approximately 85% of males who are over 50 years of age. Hydrocotyle ramiflora (HR), belonging to Apiaceae family, is used to treat urinary system diseases such as urine retention in traditional Chinese herbal medicine. In this study, we evaluated the effects of HR in the BPH animal model. METHODS We induced BPH in rats via subcutaneous (sc) injections of testosterone propionate (TP, 3 mg/kg). Rats were also administered HR (150 mg/kg), finasteride (10 mg/kg), or vehicle via oral gavage. After induction, prostate glands were collected, weighed, and processed for further analysis, including histopathological examination and immunohistochemistry. In addition, the mRNA expression of inflammatory cytokines in prostatic tissues was determined by quantitative real-time PCR (qRT-PCR). The protein expression of pro-apoptotic markers was examined using western blotting. RESULTS HR treatment significantly reduced the prostate weight, epithelial thickness, and proliferating cell nuclear antigen (PCNA) expression, with the levels of cleaved caspase-3 and Bcl-2-associated X (Bax) protein considerably increased compared to BPH group. HR also decreased inflammatory cell infiltration and pro-inflammatory cytokine levels compared with BPH group. Furthermore, the expression of phosphor-nuclear factor-κB (NF-κB), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS) were reduced by HR treatment. CONCLUSION These results indicate that HR suppresses the development of BPH associated with anti-proliferative, pro-apoptotic, and anti-inflammatory effects, suggesting it is a potential alternative therapeutic agent for BPH.

Abstract
Abstract
Background
Benign prostatic hyperplasia (BPH) and the use of CCBs are common in older persons, and are also associated with lower urinary tract symptoms (LUTS). This review summarised and synthesised relevant information and recent advances to improve clinical knowledge on the role of CCBs in LUTS, BPH symptoms and health-related quality of life.
Main body of the abstract
A search of databases of PubMed, Web of science, Hinari, and Google scholar was performed using several keywords. Relevant studies were also extracted from references of identified studies. Selected studies were assessed for content related to CCBs, BPH and LUTS, and the most relevant reports were included. The inhibition of calcium channels by CCBs interferes with influx of extracellular Ca2+ into the detrusor muscle, which interferes with bladder contraction and relaxation. Hence, CCBs are associated with precipitation or aggravation of urinary storage and voiding symptoms, which are also common symptoms of BPH. This suggests a potential aggravation of BPH symptoms with the use of CCBs.
Short conclusion
Persons at high risk of LUTS such as in BPH, may benefit from other classes of antihypertensive drugs. Therefore, it is essential to identify persons with BPH prior to commencement of therapy with CCBs. Patients on CCBs should be routinely reviewed for any potential precipitation or aggravation of LUTS. Patients should also be counselled to notify their healthcare provider of unusual urinary symptoms during CCB use. This will facilitate enhanced quality of life in patients with BPH.

Abstract
BACKGROUND Solitary fibrous tumor (SFT) is a relatively rare type of mesenchymal neoplasm that occurs most frequently in the pleura. However, SFT originating from the prostate is particularly uncommon and only approximately 39 cases were reported before. Herein, we reported a rare case of a patient diagnosed with prostate SFT and presented a literature review.Case presentation: A 50-year-old Asian with irritative urinary symptoms was admitted to our hospital and almost all the evidence indicated that benign prostate hyperplasia (BPH) caused his symptoms. Therefore, transurethral resection of the prostate (TURP) was performed, but histopathological and Immunohistochemical (IHC) assessments showed that spindle cells arranged disorderly in the TURP specimen with a cluster of differentiation 34 (CD34), B-cell lymphoma-2 (Bcl-2), and signal transducer and activator of transcription 6 (STAT6) highly expressed and SFT was diagnosed. Finally, the patient underwent a radical prostatectomy and there was no disease progression observed thereafter. CONCLUSIONS Prostate SFT is extremely rare, and to our knowledge, this is the first case of prostate SFT that is difficult to differentiate from small volume BPH. IHC examinations are of great diagnostic value. Radical resection of the tumor appears to be the most effective method at present and continuous follow-up is highly recommended.

Abstract
PURPOSE OF REVIEW We sought to perform a contemporary literature review highlighting the racial disparities which exists in the evaluation and management of benign prostatic hyperplasia (BPH). RECENT FINDINGS Current literature suggests that racial disparities exist in the diagnosis of BPH and treatment lower urinary tract symptoms (LUTS). This is seen in the presentation and diagnosis of the disease as well as a difference in preventative care with discordant incidences of medical and surgical management among racial groups. The racial disparities that exist in the diagnosis and management of BPH and LUTS require further investigation to better identify the underlying causes. This will ultimately allow for continued improvement in care delivery and a more personalized approach in patient management.

Abstract
Objective As the population aged, voiding dysfunction has been steadily rising among males during the past decade. Increasing evidence showed that sleep disorders are associated with an increasing risk of various diseases, but the association between sleep disorders and lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) among Chinese males have not been well characterized. Materials and methods We conducted a cross-sectional analysis of data from West China Natural Population Cohort Study (WCNPCS) 2019-2021. Sleep quality was assessed by Pittsburgh sleep quality index (PSQI) in Chinese version. LUTS/BPH as a dependent variable of a binary variable, assessed by a self-reported questionnaire. Multivariate logistic regression analysis were performed to evaluate the correlation between sleep disorders and the risk of LUTS/BPH after adjusting for confounding factors. Results 11,824 eligible Chinese men participated in this cross-sectional survey. In multivariate logistic regression analysis, after adjusting for confounding variables, global PSQI score (OR: 1.257, 1.119-1.411, p < 0.001) and its six compounds (Subjective sleep quality: OR: 1.376, 1.004-1.886, p = 0.048; Sleep latency: OR: 0.656, 0.557-0.773, p < 0.001; Sleep duration: OR: 1.441, 1.189-1.745, p < 0.001; Habitual sleep efficiency: OR: 1.369, 1.193-1.570, p < 0.001; Daytime dysfunction: OR: 1.702, 1.278-2.267, p < 0.001) except the use of sleep drug subgroup were significantly positively correlated with LUTS/BPH prevalence. Significant interaction effects were observed in age subgroups (age-young group: age < 51; age-middle group: 51 ≤ age ≤ 61; age-older group: age > 61) (P < 0.05). Among older participants, sleep disorders were more significantly associated with the risk of LUTS/BPH. Conclusion There was a significant association between poor sleep quality and increased prevalence of LUTS/BPH, especially among the elderly male population, suggesting an important role of healthy sleep in reducing prostate disease burden.

Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) is an age-related disease in adult men. There are two pharmacological treatments for BPH. However, these synthetic materials have various risks, many studies are being conducted to develop new drugs from natural sources. PURPOSE In this study, we proposed a beneficial effect of Glycyrrhiza uralensis Fischer on the development and progression of BPH, focusing on the androgen receptor (AR) and 5α-reductase 2 (5AR2) signaling axis. METHODS To explain the therapeutic efficacy of a water extract of G. uralensis (GUWE) for BPH, we used testosterone propionate (TP)-induced BPH rat models and TP-treated RWPE-1 human prostate epithelial cells. RESULTS In the TP-induced BPH rat models, GUWE reduced the enlarged prostate weight, prostate index, prostate epithelial thickness, and serum DHT levels. In addition, the protein levels of AR and 5AR2 in prostate tissues were significantly decreased by GUWE treatment. Furthermore, GUWE induced apoptosis signaling through an increase of Bcl-2 associated X protein (Bax), caspase 3, and Poly (ADP-ribose) polymerase (PARP) and a decrease of B-cell lymphoma-extra-large (Bcl-xL) in prostate tissues of TP-induced BPH rats. These findings were also confirmed in TP-treated RWPE-1 cells. Fi treatment markedly decreased the sperm count in the epididymis of BPH rats, but GUWE treatment did not affect the sperm count, suggesting less toxicity. CONCLUSION These findings suggested that GUWE reduces the development of BPH by inhibiting AR-5AR2 and activating the apoptosis signaling pathway. Furthermore, unlike finasteride, GUWE did not affect sperm count. Therefore, we suggest that GUWE has a potential as a safer alternative option for BPH treatment.

Bmal1 Regulates Prostate Growth via Cell-Cycle Modulation. Int J Mol Sci 2022; 23:ijms231911272. [PMID: 36232573 PMCID: PMC9569634 DOI: 10.3390/ijms231911272] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Revised: 09/19/2022] [Accepted: 09/22/2022] [Indexed: 11/21/2022] Open
Abstract
The circadian clock system exists in most organs and regulates diverse physiological processes, including growth. Here, we used a prostate-specific Bmal1-knockout mouse model (pBmal1 KO: PbsnCre+; Bmal1fx/fx) and immortalized human prostate cells (RWPE-1 and WPMY-1) to elucidate the role of the peripheral prostate clock on prostate growth. Bmal1 KO resulted in significantly decreased ventral and dorsolateral lobes with less Ki-67-positive epithelial cells than the controls. Next, the cap analysis of gene expression revealed that genes associated with cell cycles were differentially expressed in the pBmal1 KO prostate. Cdkn1a (coding p21) was diurnally expressed in the control mouse prostate, a rhythm which was disturbed in pBmal1 KO. Meanwhile, the knockdown of BMAL1 in epithelial RWPE-1 and stromal WPMY-1 cell lines decreased proliferation. Furthermore, RWPE-1 BMAL1 knockdown increased G0/G1-phase cell numbers but reduced S-phase numbers. These findings indicate that core clock gene Bmal1 is involved in prostate growth via the modulation of the cell cycle and provide a rationale for further research to link the pathogenesis of benign prostatic hyperplasia or cancer with the circadian clock.

Abstract
Benign prostatic hyperplasia (BPH) is an age-related disease, whose etiology largely remains unclear. The regulation of mitophagy plays a key role in aging and associated diseases, however, its function in BPH has not been studied. Although the expression of the androgen receptor is primarily implicated in BPH, the estrogen receptor (ER) has been reported to be involved in the development of BPH by mediating the proliferation of prostate cells. Here, we studied the involvement of mitophagy and ERs in spontaneous BPH in aging mice and investigated their functions. To identify the activation of mitophagy and expression of ERs, 8-week, 12-month, and 24-month-old mice were used. Mice were treated with mitochondrial division inhibitor mdivi-1, a dynamin-related protein 1 (Drp1) inhibitor, to examine the expression of mitophagy-related proteins and the development of BPH. In addition, prostate stromal cells were treated with an ER antagonist to investigate the regulation of mitophagy following the expression of ERs. With aging, the Drp1 and phosphorylation of parkin reduce. Electron microscopy revealed reduced mitochondrial fission and mitophagy. In addition, the expression of androgen receptor was decreased and that of ERα was increased in aged mice with BPH. Treatment with mdivi-1 exacerbated BPH and increased cell proliferation. In addition, blockade of ERα increased mitophagy and decreased cell proliferation. In conclusion, mitophagy is reduced with aging during the development of BPH. We speculate that spontaneous BPH progresses through the reduction in the expression of ERα in aged mice by downregulating mitophagy.

Abstract
Centella asiatica (L.) Urban (C. asiatica) is a traditional herbal medicine that has been used for wound healing and anti-inflammation since ancient times. Various biological effects of C. asiatica ethanolic extract (CAE) were previously reported. However, in our previous study, C. asiatica aqueous extract (CAA) exhibited higher inhibitory activity on benign prostatic hyperplasia (BPH) than CAE. Therefore, the aim of this study was to investigate the effect of CAA on BPH, and elucidate the inhibitory mechanism through in vitro and in vivo experiments as well as metabolite analysis of CAA. A BPH rat model was induced by daily subcutaneous injection of testosterone propionate (TP, 3 mg kg-1) dissolved in corn oil for 4 weeks after castration. The experimental group, the CAA treatment group, was orally administered CAA (100 mg kg-1) for 4 weeks while inducing prostatic hyperplasia. Saw palmetto extract (Saw, 100 mg kg-1) and Finasteride (Fi, 1 mg kg-1) were used as positive controls and were administered orally for 4 weeks. CAA significantly inhibited androgen receptor signaling related factors overexpressed by dihydrotestosterone (DHT) treatment in prostate cell lines. Afterwards, the testosterone-induced BPH model was used to verify the alleviation efficacy of CAA in prostatic hyperplasia. Prostate size and the thickness of the prostate tissue epithelium were significantly decreased in the group treated with CAA compared to those in the BPH group. The results of protein expression in the prostate tissue confirmed that CAA inhibited androgen receptor signaling in BPH and decreased the expression of growth factors. Moreover, CAA suppressed the expression of the PI3K/Akt pathway and cell proliferation-related factors compared to the BPH group. Taken together, these results indicate that CAA improves the inhibitory efficacy of BPH by inhibiting the androgen receptor and PI3K/Akt pathways, suggesting that CAA may be a promising candidate for biopharmaceutical formulations of BPH.
