Abstract
Prostate enlargement due to benign prostate hyperplasia (BPH) is a common, progressive disorder in elderly males with increasing prevalence. It causes devastating lower urinary tract symptoms with no satisfactory medication. Asiatic acid (AA), a natural pentacyclic triterpenoid, is known to have antiproliferative, antioxidant, and anti-inflammatory activities. The aim of this study was to evaluate the possible preventive activities of AA against BPH induced by testosterone in rats. Finasteride (0.5 mg/kg) was used as a reference drug. AA (10 or 20 mg/kg) administration inhibited the rise in prostatic weight and index induced by testosterone. Histopathological staining proved that AA mitigated the pathological features of BPH induced by testosterone, which was reflected as lower glandular epithelial in AA-treated groups. Also, the administration of AA along with testosterone restored the redox valance by inhibiting lipid peroxidation, and MDA production, and restoring the activities of superoxide dismutase (SOD) and catalase (CAT) activities. Also, AA reduced prostate interleukin-6 (IL-6), cyclooxygenase-2 (COX-2), tumor necrosis factor-alpha (TNF-α), and nuclear factor-kappa B (NF-κB) protein expression. In addition, AA modulated mRNA expression of Bax and Bcl-2 in favor of apoptosis. The effects of AA (20 mg/kg) were comparable to those of finasteride. Further, AA ameliorated the rise in insulin-like growth factor 1 receptor (IGF-1R) mRNA expression. This was associated with the enhancement of the prostatic content of PPAR-γ. It can be concluded that AA mitigated the features of BPH induced by testosterone in rats. This involves antioxidant, anti-inflammatory and pro-apototic activities of AA as well as its ability to down-regulate IGF-1R expression and enhance PPAR-γ concentration in prostatic tissues.

Krishnamoorthi R, Ganapathy A A, Hari Priya VM, Kumaran A. Future aspects of plant derived bioactive metabolites as therapeutics to combat benign prostatic hyperplasia. JOURNAL OF ETHNOPHARMACOLOGY 2024; 330:118207. [PMID: 38636573 DOI: 10.1016/j.jep.2024.118207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 04/12/2024] [Accepted: 04/14/2024] [Indexed: 04/20/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Benign prostatic hyperplasia (BPH), characterized by prostate enlargement due to cell proliferation, is a common urinary disorder in men over 50, manifesting as lower urinary tract symptoms (LUTS). Currently, several therapeutic options are accessible for treating BPH, including medication therapy, surgery and watchful waiting. Conventional drugs such as finasteride and dutasteride are used as 5α-reductase inhibitors for the treatment of BPH. However long-term use of these drugs is restricted due to their unpleasant side effects. Despite the range of available medical therapies, the effective treatment against BPH is still inadequate. Certain therapeutic plants and their phytochemicals have the aforementioned goals and work by regulating this enzyme. AIM OF THE STUDY This review aims to provide a comprehensive insight to advancements in diagnosis of BPH, modern treatment methods and the significance of ethnobotanically relevant medicinal plants as alternative therapeutics for managing BPH. MATERIAL AND METHODS A thorough and systematic literature search was performed using electronic databases and search engines such as PubMed, Web of Science, NCBI and SciFinder till October 2023. Specific keywords such as "benign prostatic hyperplasia", "medicinal plants", "phytochemicals", "pharmacology", "synergy", "ethnobotany", "5-alpha reductase", "alpha blocker" and "toxicology". By include these keywords, a thorough investigation of pertinent papers was assured, and important data about the many facets of BPH could be retrieved. RESULTS After conducting the above investigation, 104 herbal remedies were found to inhibit Phosphodiesterase-5 (PDE-5) inhibition, alpha-blockers, or 5α -reductase inhibition effects which are supported by in vitro, in vivo and clinical trial studies evidence. Of these, 89 plants have ethnobotanical significance as alpha-blockers, alpha-reductase inhibition, or PDE-5 inhibition, and the other fifteen plants were chosen based on their ability to reduce BPH risk factors. Several phytocompounds, including, rutaecarpine, vaccarin, rutin, kaempferol, β-sitosterol, quercetin, dicaffeoylquinic acid, rutaevin, and phytosterol-F have been reported to be useful for the management of BPH. The use of combination therapy offers a strong approach to treating long-term conditions compare to single plant extract drugs. Furthermore, several botanical combinations such as lycopene and curcumin, pumpkin seed oil and saw palmetto oil, combinations of extracts from Funtumia africana (Benth.) Stapf and Abutilon mauritianum (Jacq.) Medik., and Hypselodelphys poggeana (K.Schum.) Milne-Redh. and Spermacoce radiata (DC.) Sieber ex Hiern are also supported through in vitro and in vivo studies for managing BPH through recuperation in patients with chronic long-term illnesses, as measured by the International Prostate Symptom Score. CONCLUSION The review proposes and endorses careful utilization of conventional medications that may be investigated further to discover possible PDE-5, 5 alpha-reductase, an alpha-blocker inhibitor for managing BPH. Even though most conventional formulations, such as 5 alpha-reductase, are readily available, systemic assessment of the effectiveness and mechanism of action of the herbal constituents is still necessary to identify novel chemical moieties that can be further developed for maximum efficacy. However, there exist abundant botanicals and medicinal plants across several regions of Africa, Asia, and the Americas, which can be further studied and developed for utilization as a potential phytotherapeutic for the management of BPH.

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
Benign prostatic hyperplasia (BPH), characterized by the enlargement of the prostate gland and subsequent lower urinary tract symptoms, poses a significant health concern for aging men with increasing prevalence. Extensive efforts encompassing in vitro and in vivo models are underway to identify novel and effective agents for the management and treatment of BPH. Research endeavors are primarily channeled toward assessing the potential of compounds to inhibit cell proliferation, curb inflammation, and display anti-androgenic activity. Notably, through screening aimed at inhibiting 5-alpha reductase type 2 (5αR2) in human prostatic cells, two acyl compounds (1 and 2) were isolated from a bioactive fraction sourced from an association of marine sponges Poecillastra sp. and Jaspis sp. The complete structure of 1 was determined as (Z)-dec-3-enony (2S, 3S)-capreomycidine, ascertained by JBCA and ECD comparison. While the absolute configurations of 2 remained unassigned, it was identified as a linkage of a 2, 7S*-dihydoxy-9R*-methyloctadecanoyl group with the 2-amino position of a tramiprosate moiety referred to as homotaurine. Evaluation of both compounds encompassed the assessment of their inhibitory effects on key biomarkers (5αR2, AR, PSA, and PCNA) associated with BPH in testosterone propionate (TP)-activated LNCap and RWPE-1 cells.

Abstract
Benign prostatic hyperplasia (BPH) is a chronic, progressive disease characterized by mesenchymal cell-predominance and stromal and glandular cell-hyperproliferation. Although, the precise cause of BPH is unknown, it is believed to be associated with hormonal changes in aging men. Despite androgens and ageing are likely to play a role in the development of BPH, the pathophysiology of BPH remains uncertain. This paper aims to evaluate the diagnostic efficacy of platelet-to-lymphocyte ratio (PLR), neutrophil-lymphocyte ratio (NLR) and systemic immune-inflammation index in in diagnosing BPH. A single-center-randomized-retrospective study was carried out at Alzahraa university hospital between January 2022 and November 2022 on 80 participants (40 non-BPH subjects and 40 patients with symptomatic enlarged prostate) who visited the outpatient clinic or admitted to the urology department. The BPH cases were evaluated by digital rectal examination (DRE), International Prostate Symptom Score (IPSS), prostate size, prostate specific antigen (PSA), TRUS biopsy in elevated PSA > 4 ng/ml, PLR, NLR and systemic immune inflammatory (SII). The diagnosing efficiency of the selected parameters was evaluated using Receiver Operating Characteristic (ROC) and Artificial Neural Network (ANN) showing excellent discrimination with 100% accuracy and AUC = 1 in the ROC curves. Moreover, the accuracy rate of the ANN exceeds 99%. Conclusion: PLR, NLR and SII can be significantly employed for diagnosing BPH.

Abstract
Introduction Platelet indices changes in severely ill people and in dogs with inflammation are compatible findings. This study aimed to compare platelet indices between dogs with clinical benign prostatic hyperplasia (BPH) and healthy controls. Additionally, to determine whether there is a correlation between the relative prostatic size (S rel) and the platelet indices in BPH dogs. Methods Thirty-five adult intact male dogs of different breeds were allocated to the experimental groups: dogs with clinical BPH (groups A; n = 24; median age of 6 years; the median weight of 8.50 kg) and healthy dogs (group B; n = 11; median age 5.50 years; the median weight of 7.00 kg) based on physical examination, clinical signs, and S rel detected by ultrasonographic findings. The individual prostatic volume (IPV) was divided by the expected prostatic volume (EPV) to determine the relative prostatic size in dogs over 4 years old. Platelet indices were compared between the two groups, and a correlation between S rel and these indices was calculated. Results The median S rel of dogs in group A was significantly higher (P = 0.001), and the mean plateletcrit (PCT) was significantly lower (P = 0.003) compared with those in group B. S rel showed a significant negative correlation with PLT and PCT (r = -0.388; P = 0.02 and r = -0.402; P = 0.01). Receiver operating characteristic (ROC) analysis showed PLT and PCT thresholds for estimating S rel > 1 with 75% and 87.5% sensitivity and 71.82 and 63.64% specificity. Discussion The findings of this study support the use of platelet indices like PLT and PCT to detect clinical BPH in dogs. However, more research is needed to confirm their utility in conjunction with other previously described diagnostic factors.

Abstract
AIMS In this study, we used a near-infrared laser (NIR) to increase the potency of silver nanoparticles (AgNPs) to develop a novel, less invasive, and simple photothermal therapy technique for benign prostate hyperplasia (BPH). MATERIALS AND METHODS The shape, particle size, and zeta-potential of polyvinylpyrrolidone coated-AgNPs (PVP-AgNPs) were determined using transmission electron microscopy (TEM), Zeta-potential, and Particle size analyzer (ELSZ). To induce BPH, thirty-six male Sprague-Dawley (SD) rats were given intramuscular (i.m) injections of testosterone propionate (TP) at 5 mg/kg body weight (b.w)/day suspended in 0.1 ml of olive oil for 14 days. Photothermal therapy with AgNPs-NIR for 14 days was carried out. Prostate size, prostate index (PI), dihydrotestosterone (DHT), prostate-specific antigen (PSA), gross, hepatic, and renal toxicity, as well as antioxidant activity, apoptosis, and angiogenesis markers in prostatic tissues were measured. Histological examinations of prostates and biocompatibility of NIR-AgNPs on vital organs were also performed. KEY FINDINGS The aggregated spherical AgNPs with a mean size of 50-90 nm and a Zeta potential of -53.22 mV displayed high effectiveness in the NIR (532 nm-1 W) region by decreasing prostate size, PI, DHT, and PSA in BPH rats with no signs of gross, hepatic, or renal damage. As compared to alternative therapies, hyperthermia therapy increased antioxidant activities, induced apoptosis, inhibited angiogenesis, reduced histological alterations in the prostates of BPH rats, and improved biocompatibility of the vital organs. SIGNIFICANCE The current study demonstrated the effectiveness of plasmonic AgNPs photothermal therapy in the treatment of BPH.

Abstract
Prostate cancer (PC) is one of the most common malignancies among men and is the second leading cause of cancer death. PC immunotherapy has taken relatively successful steps in recent years, and these treatments are still being developed and tested. Evidence suggests that immunotherapy using cytokines as essential mediators in the immune system may help treat cancer. It has been shown that cytokines play an important role in anti-tumor defense. On the other hand, other cytokines can also favor the tumor and suppress anti-tumor responses. Moreover, the dose of cytokine in cancer cytokine-based immunotherapy, as well as the side effects of high doses, can also affect the outcomes of treatment. Cytokines can also be determinative in the outcome of other immunotherapy methods used in PC. In this review, the role of cytokines in the pathogenesis of cancer and their impacts on the main types of immunotherapies in the treatment of PC are discussed.

Abstract
BACKGROUND Inflammation is crucial in the pathogenesis of lower urinary tract symptoms (LUTS) in men. Diet modulates inflammation. Therefore, diet could be a modifiable factor in male LUTS prevention and treatment. We aimed to investigate the association between dietary inflammatory potential and male LUTS. METHODS We used two cycles of National Health and Nutrition Examination Survey (NHANES) with self-report LUTS data. We calculated the dietary inflammatory index (DII) based on a 24 h diet recall and evaluated male LUTS. Clinical LUTS was defined as two or more coexisting symptoms. We used univariate and multivariate logistic regression models, the smooth curve fitting to analyze the relationship between clinical LUTS and the DII score. Subgroup analyses were conducted. RESULTS We observed a positive non-linear relationship between clinical LUTS and DII. We found that when DII was higher than the inflection point 2.39, a 1-unit increase in DII was associated with 26.1% higher adjusted odds of clinical LUTS. Subgroup analyses showed that the DII score was only positively correlated with clinical LUTS risk in non-drinkers, smokers, and non-obese people (DII >2.39). CONCLUSIONS Inflammation might be the key mechanism bridging dietary consumption to male LUTS. Excessive pro-inflammatory food intake (DII >2.39) warrants special vigilance, especially for non-drinkers, smokers, and non-obese men.

Abstract
Pharmacological treatment for BPH includes 5-α reductase inhibitors as Finasteride and Dutasteride as a monotherapy or in combination with antimuscarinic drugs, alpha-blockers, 5-phosphodiesterase inhibitor drugs. Androgen receptor inhibitors revealed several adverse events as decreased libido, erectile dysfunction, ejaculatory dysfunction, and gynecomastia. Hence, the emergence of complementary and alternative medications having safety profile—preferably, edible natural products—would be highly desirable. In-silico studies based on Maestro Molecular Modelling platform (version 10.5) by Schrӧdinger, LLC was used to identify the lead molecules. The in-vivo activity studied on rats gave the positive results. The findings based on experiments as antioxidant parameters showed the potential to quench the free radicals. The significant results were also seen in prostatic index and histopathological studies supported the above findings. Based on these data, sesamol and derivative have proven efficacy in protecting against testosterone induced BPH.

Abstract
We investigated whether tryptase released from mast cells activated by prostate stromal cells (PSC) reacted with Trichomonas vaginalis (Tv) promoted the proliferation of PSC through protease- activated receptor 2 (PAR2). Conditioned medium of PSC was prepared by stimulating them with Tv (Trichomonad-conditioned medium (TCM)), and mast cell-conditioned medium were prepared by incubating them with TCM (mast cell-TCM (M-TCM)). Mast cells incubated with TCM migrated more efficiently and produced more β-hexosaminidase and tryptase. M-TCM containing tryptase increased the proliferation of PSC, while inhibition of tryptase decreased proliferation. Expression of signalling molecules such as PAR2, p-ERK, COX-2, 15d-PGJ2 and PPARγ, known to be involved in the tryptase-PAR2 pathway, increased in response to M-TCM, and blocking any of these signals decreased proliferation, indicating that tryptase-PAR2 signalling is involved in the proliferation of PSC. Inhibition of tryptase and PAR2 led to reduced expression of PAR2, p-ERK, COX-2, 15d-PGJ2 and PPARγ, while inhibition of ERK or COX-2 reduced the expression of COX-2, 15d-PGJ2 and PPARγ indicating that the tryptase-PAR2 pathway proceeds in the order p-ERK, COX-2, 15d-PGJ2 , and PPARγ. These results show that interaction between PSC stimulated with Tv and mast cells causes proliferation of PSC through the tryptase-PAR2 pathway.

Abstract
Finasteride used for treating benign prostatic hyperplasia is associated with undesirable side effects via oxidative stress related mechanisms. This study employed in vivo and in silico methods to investigate the protective role of hesperidin against testicular toxicity induced by finasteride and the possible molecular mechanisms involved. Male Wistar rats were randomized into four groups of six animals each. Group I (control) were administered distilled water, group II received finasteride (3.1 mg/kg bw), group III received hesperidin (100 mg/kg bw), while group IV were co-administered finasteride and hesperidin. Administration was by gavage for 14 days. The binding propensities of finasteride and hesperidin for 5α-reductase were assessed using in silico docking approach. Finasteride administration caused significant reductions of sperm motility, volume, count, and live/dead ratio, with significant increase in numbers of abnormal sperms. Finasteride treatment also resulted in diminished activities of superoxide dismutase, catalase and glutathione-S-transferase, significant reduction in the concentration of reduced glutathione and ascorbic acid, and increased testicular malondialdehyde level relative to control. Moreover, significant increase in the activities of testicular lactate dehydrogenase and γ-glutamyl transferase was observed, with significant decrease in the activities of acid phosphatase and alkaline phosphatase relative to finasteride-treated rats. Furthermore, hesperidin exhibited favorable binding affinity for 5α -reductase (5AR) in silico compared to finasteride. Co-administration with hesperidin ameliorated finasteride-induced testicular damage by suppressing oxidative stress indices, enhancing antioxidant status, improving sperm parameters and alterations in the activities of marker enzymes, as well as possibly inhibiting the binding of finasteride to 5AR.

Abstract
Benign prostatic hyperplasia (BPH) is a progressive proliferative disease, the incidence of which is constantly increasing due to aging of population. In this research, a hexokinase-II enzyme inhibiting agent, lonidamine - the use of which is limited in BPH treatment due to high hepatic toxicity observed after three months of treatment - was selected as an active agent, based on its mechanism of action in treating BPH. The aim of this study was to evaluate in vivo therapeutic efficacy and hepatic toxicity of lipid-polymer hybrid nanoparticles of lonidamine in a rat BPH model created in rat prostates. After local injections of hybrid nanoparticles of lonidamine were administered to the rat prostates, hyperplasic structures of prostates were evaluated in terms of prostatic index values, immunohistochemical evaluations, and histopathological findings. Liver blood enzyme values were also determined to specify hepatic toxicity. Apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) reaction and histopathological methods to determine intravital degenerative destruction in liver. Through this study, lonidamine-loaded hybrid nanoparticles were found to reduce the hepatic toxicity and increase therapeutic efficiency of lonidamine. Therefore, lonidamine-entrapped hybrid nanoparticles may provide a promising, and very safe, drug delivery strategy in the treatment of BPH.

Abstract
Objectives: This work investigated the effect of acetogenin-rich fraction of Annona muricata leaves (AFAL) on antioxidant status and some markers of benign prostatic hyperplasia (BPH) in rats. Methods: BPH was experimentally induced in the rats by subcutaneous injection of testosterone propionate (TP, 3 mg/kg) for 28 consecutive days. The rats were administered orally different doses of AFAL (100 and 200 mg/kg) for 7 days. Prostate-specific antigen (PSA), prostate weight, relative prostate weight, prostate protein content and oxidative stress indices of the rats were evaluated. Results: It was observed that 200 mg/kg AFAL significantly reduced the PSA level, mean prostate weights and mean relative prostate weights of the test rats compared to the TP group, and the values were not significantly different from the normal control and group treated with a standard drug. The plant extract also significantly enhanced the antioxidant capacity of the test rats which were evidently compromised in the group that received the exogenous hormone alone. Histopathology of the prostate showed a marked recovery for the test rats after treatment with AFAL. Conclusion: Oral administration of acetogenin-rich fraction of Annona muricata leaves ameliorated TP-induced BPH in rats and significantly enhanced the antioxidant capacity of the rats.

Abstract
Benign prostatic hyperplasia (BPH) is a progressive pathological condition associated with proliferation of prostatic tissues, prostate enlargement, and lower-urinary tract symptoms. However, the mechanism underlying the pathogenesis of BPH is unclear. The aim of this study was to investigate the protective effects of a combination of Stauntonia hexaphylla and Cornus officinalis (SC extract) on a testosterone propionate (TP)-induced BPH model. The effect of SC extract was examined in a TP-induced human prostate adenocarcinoma cell line. Male Sprague-Dawley rats were randomly divided into 5 groups (n = 6) for in vivo experiments. To induce BPH, all rats, except those in the control group, were administered daily with subcutaneous injections of TP (5 mg/kg) and orally treated with appropriate phosphate buffered saline/drugs (finasteride/saw palmetto/SC extract) for 4 consecutive weeks. SC extract significantly downregulated the androgen receptor (AR), prostate specific antigen (PSA), and 5α-reductase type 2 in TP-induced BPH in vitro. In in vivo experiments, SC extract significantly reduced prostate weight, size, serum testosterone, and dihydrotestosterone (DHT) levels. Histologically, SC extract markedly recovered TP-induced abnormalities and reduced prostatic hyperplasia, thereby improving the histo-architecture of TP-induced BPH rats. SC extract also significantly downregulated AR and PSA expression, as assayed using immunoblotting. Immunostaining revealed that SC extract markedly reduced the 5α-reductase type 2 and significantly downregulated the expression of proliferating cell nuclear antigen. In addition, immunoblotting of B-cell lymphoma 2 (Bcl-2) family proteins indicated that SC extract significantly downregulated anti-apoptotic Bcl-2 and markedly upregulated pro-apoptotic B cell lymphoma-associated X (Bax) expression. Furthermore, SC treatment significantly decreased the Bcl-2/Bax ratio, indicating induced prostate cell apoptosis in TP-induced BPH rats. Thus, our findings demonstrated that SC extract protects against BPH by inhibiting 5α-reductase type 2 and inducing prostate cell apoptosis. Therefore, SC extract might be useful in the clinical treatment of BPH.

Abstract
The prostatotropic activity of glycyrrhizic acid disodium salt (Na2GA) was studied in the models of benign prostatic hyperplasia (BPH) induced by chronic injection of sulpiride (40 mg/kg intraperitoneally for 8 weeks) or testosterone propionate (20 mg/kg subcutaneously for 4 weeks) in the Wistar rats. The oral administration of Na2GA in a dose of 100 mg/kg produced a moderate antiproliferative effect in both BPH models resulting in reduced volume density of prostatic epithelium (in the testosterone model) and increased volume density of the glandular lumen (in both models). The observed prostatotropic effects of Na2GA were similar to those of Permixon and finasteride, but they were less pronounced as confirmed by smaller drops in epithelial volume density and epithelial-to-stromal ratio compared to the effects of both reference drugs.

Abstract
Abstract
Background
To examine the relation of baseline serum prostatic-specific antigen (PSA) to symptomatic changes in men with benign prostatic hyperplasia (BPH) receiving tamsulosin through its relation to changes in international prostate symptom score (IPSS) and maximum urinary flow rate (Qmax) and the occurrence of acute urine retention (AUR).
Results
We conducted a multicentric prospective cohort study. BPH patients were included from May 2015 till January 2018. We collected IPSS recording, prostate volume (PV) Qmax. After 2 years of medical treatment with tamsulosin 0.4 mg once daily, full initial evaluation was repeated for all patients. Improvement in IPSS and Qmax was recorded and compared to initial PSA levels. Follow-up was aborted for patients who developed AUR. Moreover, the data of AUR patients were recorded and compared to initial PSA levels. The study included 437 Egyptian patients, and 414 patients (94.7%) had symptomatic improvement through the 2 years of follow-up on tamsulosin monotherapy. In total, 23 patients (5.3%) developed AUR during follow-up. There was a significant association between AUR and higher baseline PSA level (p < 0.001). On the other hand, statistical analysis showed that there was no significant correlation between baseline serum PSA and the improvement in IPSS (r = − 0.02, p = 0.684) or Qmax (r = − 0.06, p = 0.267). The multivariate analysis showed that baseline PSA and PV were independent predictors for AUR (p < 0.001 for both).
Conclusions
There was a significant relation between baseline PSA and incidence of AUR. However, there was no significant relationship between the serum PSA level and symptoms improvement in BPH.

Abstract
The effect of Rhodiola sachalinensis Boriss extract irradiated with 50 kGy gamma rays (HKC) on benign prostatic hyperplasia (BPH) was investigated. Seven-week-old male SD rats received a subcutaneous injection of 20 mg/kg of testosterone propionate (TP) to induce BPH. Then, the testosterone only group received testosterone, the testosterone + finasteride group received testosterone and finasteride (5 mg/kg), the testosterone + HKC group received testosterone and HKC extract (500 mg/kg). Prostate weight and the dihydrotestosterone (DHT) levels in serum or prostate tissue were determined. The mRNA expressions of 5-alpha reductase (AR) in prostate tissue were also measured. Compared to the control group, prostate weight was significantly improved in the TP group and decreased in the HKC and finasteride-treated groups. Furthermore, the mRNA expression of 5-AR in the prostate was significantly reduced in the HKC and finasteride-treated groups. Similarly, the expression levels of α-smooth muscle actin (α-SMA) and cytokeratin, which are associated with prostatic enlargement in the HKC and finasteride groups, were much lower than in the TP group. HKC treatment showed similar efficacy to finasteride treatment on rats with testosterone-induced BPH. HKC may be explored as a potential new drug for BPH treatment.

Abstract
Prostatotropic activity of (3,5-dimethyl-4-hydroxy)benzyl thiododecane (T-DD) was evaluated on a model of benign prostatic hyperplasia induced in Wistar rats by chronic (2 months) intraperitoneal administration of sulpiride (40 mg/kg). Morphometric analysis of the dorsolateral lobe of the prostate showed that after the 2-month course of intragastric T-DD (100 mg/kg) administered in parallel with sulpiride, the volume density of glandular epithelium decreased by 1.7 times, while the volume density of prostate stroma increased by 2 times. After administration of the reference drug Permixon at a dose of 50 mg/kg, the volume densities of epithelium decreased by 1.3 times and stromal volume density increased by 1.5 times. The observed effects are presumably related to suppression of 5α-reductase activity and modulation of estrogen receptors in the prostate.

Abstract
Objective To analyze the association between neutrophil‐to‐lymphocyte ratio (NLR) and intravesical prostatic protrusion (IPP) in men with benign prostatic hyperplasia. Methods Two hundred and fifty men aged >50 years who presented with lower urinary tract symptoms at our institution between 2014 and 2018 were analyzed. Pearson's method was used for analysis of the correlation between NLR and IPP. Multivariate logistic regression analysis was used to identify predictors of IPP. Further analysis according to total prostate volume (TPV) was performed. Results The NLR correlated positively with IPP (Pearson's r = 0.459, P < 0.001) and was an independent predictor of IPP ≥10 mm (odds ratio, 2.95; 95% confidence interval, 1.59–5.47; P = 0.0006). Among the 142 men with prostates <40 cm3, mean NLR was 2.50 ± 0.71 in those with IPP ≥10 mm and 1.71 ± 0.57 in those with IPP < 10 mm (P < 0.001). The NLR differed significantly between those with a prostate <40 cm3 and IPP ≥10 mm and those with a larger prostate and IPP < 10 mm (2.50 ± 0.71 vs 2.07 ± 0.77, respectively; P = 0.020). Conclusions NLR can be used as a surrogate marker for presence of IPP. Its clinical value would be especially important in men with a small prostate gland but high IPP. The NLR seemed to be more strongly correlated with IPP than with TPV.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plants of Epilobium angustifolium are popular in China to treatment of traumatic injury, subduing inflammation and menstrual disorders. In European, the preparations or extracts containing E. angustifolium are popular to treat prostate diseases. Recent research suggested that E. angustifolium showed therapeutic effects in early stage of BPH, inflammation of urethra and prostate, as well as micturition problems. And the related researches were focus on aqueous extract and its main constituent of oenothein B. AIM OF THE STUDY This study aims to evaluate the therapeutic effect against BPH of the ethyl acetate extracts (EAE) and n-butanol extracts (BUE) from E. angustifolium and to chemical investigation of the active constituents. MATERIALS AND METHODS The in vitro anti-BPH activity was assessed by determining the benign prostatic hyperplasia epithelial-1 (BPH-1) cell viability using MTT assay as well as suppressing of prostate specific antigen (PSA) secretion in prostate epithelial cancer hormone-dependent (LNCaP) cells measured by ELISA method. The in vivo anti-BPH was evaluated by testosterone propionate induced BPH SD rats. After oral administration of BUE at 100, 200 and 400 mg/kg B.W. for 28 days, the prostate weight and index, plasma androgen level, histopathological alteration, oxidative and inflammatory-related factors in prostate were assessed. Phytochemical investigation on active extracts was carried by chromatographic and spectroscopic techniques. Anti-BPH activities of the isolates were evaluated in vitro. RESULTS BUE and EAE from E. angustifolium exhibited significant anti-BPH effect in vitro. Further in vivo study demonstrated that BUE exhibited therapeutic effects against TP-induced BPH in SD rats via down-regulating of the androgen level, suppressing the expression of NF-κB and eventually alleviating the inflammatory responses and oxidative stress. Phytochemical research on BUE and EAE extracts led to the isolation and identification of 50 compounds. In vitro anti-BPH screening revealed that 26 compounds exhibited anti-proliferation in BHP-1 cell and 36 compounds showed PSA inhibition in LNCap cell, in which 7 compounds exhibited very significant anti-BPH activities in both two cell lines (P < 0.01), 5 compounds with extremely significant activities in one of the cell lines (P < 0.001), and compound 25 exhibited the most potent anti-BPH activity (P < 0.001). CONCLUSIONS E. angustifolium exhibited the therapeutic potential against BPH, and its active compounds may be used as candidate for treatment of BPH.

Efficacy and Safety of Serenoa repens Extract Among Patients with Benign Prostatic Hyperplasia in China: A Multicenter, Randomized, Double-blind, Placebo-controlled Trial. Urology 2019; 129:172-179. [PMID: 30880074 DOI: 10.1016/j.urology.2019.02.030] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Revised: 02/16/2019] [Accepted: 02/27/2019] [Indexed: 02/05/2023]
Abstract
OBJECTIVE To evaluate the efficacy and safety of Serenoa repens among patients with benign prostatic hyperplasia (lower urinary tract symptoms/benign prostatic hyperplasia [LUTS/BPH]) in China. METHODS We conducted a double blind, placebo-controlled study of 354 patients with LUTS/BPH from 19 institutions, to evaluate the efficacy and safety of Serenoa repens. Participants were randomly assigned (1:1) into the Serenoa repens extract (320 mg) or placebo groups for 24 weeks. Primary efficacy parameters were changes in International Prostate Symptom Score and peak urinary flow from baseline to each assessment. Secondary efficacy parameters included improvement of storage symptom and voiding symptom scores, prostate volume, urinary frequency, and total prostate-specific antigen level. Other parameters assessed were quality of life score, a four-item male sexual function questionnaire score, and International Index of Erectile Function score across the consecutive double-blind visits. RESULTS Statistically significant improvement in the peak urinary flow, International Prostate Symptom Score, scores of storage symptoms and voiding symptoms, quality of life score, four-item male sexual function questionnaire score, and International Index of Erectile Function score were observed in the Serenoa repens extract group compared with those in the placebo group (P <.05). Two (1.18%) of 169 patients in the placebo group and 3 (1.89) of 159 patients in the Serenoa repens extract group experienced 1 or more adverse events. CONCLUSION The Serenoa repens extract was effective, safe, well-tolerated, and clinically and statistically superior to placebo in the target LUTS/BPH population.

Botanical Formulation HX109 Ameliorates TP-Induced Benign Prostate Hyperplasia in Rat Model and Inhibits Androgen Receptor Signaling by Upregulating Ca 2+/CaMKKβ and ATF3 in LNCaP Cells. Nutrients 2018; 10:nu10121946. [PMID: 30544543 PMCID: PMC6316726 DOI: 10.3390/nu10121946] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2018] [Revised: 11/30/2018] [Accepted: 12/05/2018] [Indexed: 11/17/2022] Open
Abstract
Benign prostatic hyperplasia (BPH) is a common disease in the elderly male population throughout the world. Among other factors, androgen dysregulation has been known to play major roles in its pathogenesis. HX109 is a botanical formulation prepared from a mixture of Taraxacum officinale, Cuscuta australis, and Nelumbo nucifera, which have traditionally been used—usually along with other plants—to treat urinary diseases. An ethanol extract was prepared from a mixture of these three plants, and its quality was controlled through cell-based bioassays and by quantification of several marker compounds by high-performance liquid chromatography (HPLC). In the testosterone propionate (TP)-induced prostate hyperplasia rat model, oral administration of HX109 ameliorated prostate enlargement and histological changes induced by TP. In LNCaP cells, a human prostate epithelial cell line, HX109 repressed AR-mediated cell proliferation and the induction of androgen receptor (AR) target genes at the transcriptional level without affecting the translocation or expression of AR. Such effects of HX109 on AR signaling were mediated through the control of activating transcriptional factor 3 (ATF3) expression, phosphorylation of calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ), and increases in intracellular calcium, as evidenced by data from experiments involving ATF3-specific siRNA, CaMKKβ inhibitor, and calcium chelator, respectively. Taken together, our data suggest that HX109 might be used as a starting point for developing therapeutic agents for the treatment of BPH.

Abstract
Benign prostatic hyperplasia (BPH), an age-dependent disorder with a prevalence percentage of 60% in the 60s, has been found to involve an androgenic hormone imbalance that causes confusion between cell apoptosis and proliferation. Because general medications for BPH treatment have undesirable side effects, the development of effective alternative medicines has been considered. HBX-5 is a newly developed formula with the aim of improving BPH, and is composed of nine medicinal herbs. BPH was induced in the rats by intramuscular injection of testosterone propionate after castration. Rats were divided into six groups, and the efficacy of HBX-5 on testosterone-induced BPH in rats was estimated. In addition, RWPE-1 and WPMY-1 cells were used to demonstrate the effect of HBX-5 on BPH in vitro model. Compared with the control group, HBX-5 administration group suppressed BPH manifestations, such as excessive development of prostate, and increase of serum dihydrotestosterone and 5α-reductase concentrations. Furthermore, immunohistochemistry analysis revealed that HBX-5 significantly decreased the expression of androgen receptor (AR) and proliferating cell nuclear antigen (PCNA). In addition, results of RWPE-1 and WPMY-1 cells showed that HBX-5 inhibited the over-expression of AR and PSA in DHT-induced prostate hyperplastic microenvironments.

Abstract
Benign prostatic hyperplasia (BPH) is the most common urological disease in elderly men. Epidemiological data suggest a causal link between this condition and prostatic inflammation. The prostate is an immune-competent organ characterized by the presence of a complex immune system. Several stimuli, including infectious agents, urinary reflux, metabolic syndrome, the ageing process, and autoimmune response, have been described as triggers for the dysregulation of the prostatic immune system via different molecular pathways involving the development of inflammatory infiltrates. From a pathophysiological standpoint, subsequent tissue damage and chronic tissue healing could result in the development of BPH nodules.

Abstract
PURPOSE The incidence of benign prostatic hyperplasia increases among obese individuals, but few studies have fully explained the underlying mechanisms. Adiponectin has drawn much attention in recent years due to its protective role in obesity-related diseases. Here we aimed to investigate the possible molecular mechanisms and clinical significance of adiponectin in relation to benign prostatic hyperplasia. METHODS We analyzed data from 98 Chinese men, including 48 BPH cases and 50 controls in a case-control study. Then, we utilized a tissue microarray analysis to examine expression of AdipoR1 and p-p90RSK in normal and hyperplastic prostate tissues. These studies were followed by various in vitro approaches to examine the anti-proliferation effect and signaling pathways of adiponectin involved in benign prostatic hyperplasia. RESULTS Lower serum adiponectin levels were independently associated with larger prostate volume and an increased risk of benign prostatic hyperplasia. Benign prostatic hyperplasia tissues had a decreased expression of AdipoR1 and increased expression of p-p90RSK compared with normal prostate tissues. in vitro, adiponectin inhibited the proliferation of prostatic epithelial and stromal cells and arrested cells in the G0/G1 phase by decreasing phosphorylation of the MEK-ERK-p90RSK axis. CONCLUSIONS Our results suggest a possible negative regulatory mechanism in which adiponectin signaling antagonizes ERK-mediated cell proliferation, and a deficiency in adiponectin could facilitate the proliferation of prostate cells and consequently contribute to benign prostatic hyperplasia.

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

Abstract
This prospective analysis assessed the effect of histological prostatitis on lower urinary tract functions and sexual function. The patients were separated into two groups as histologically observed prostatitis (Group A) and no prostatitis (Group B) according to the biopsy outcomes. International prostate symptom score, international index of erectile function-5 scores, maximal and average flow rate, and residual urine volumes were compared statistically between groups. There was no significant difference (P>0.05) in baseline age (t=0.64), body mass index value (t=0.51), prostate volume (t=0.87), prostate-specific antigen levels (t=0.43), maximal (t=0.84) and average flow rate (t=0.59), and post-void residual urine volume (t=0.71). Mean international prostate symptom score in patients with prostatitis was numerically but not significantly higher than that in those without prostatitis (t=0.794, P=0.066). Mean international index of erectile function-5 score in the prostatitis group was significantly lower than that in those without prostatitis (t=1.854, P=0.013). Histological prostatitis notably affected sexual function of patients and may serve as a major risk factor for sexual dysfunction while having little effect on lower urinary tract symptoms.

Abstract
The incidence of benign prostatic hyperplasia (BPH) is increasing among obese individuals, but few studies have fully explained the underlying mechanisms. We aimed to elucidate the relationship between obesity and BPH. Herein, we show that in prostatic epithelial and stromal cells, adiponectin exerts multifunctional effects including anti-proliferation, blocking of G1/S-phase progression and the promotion of apoptosis via inhibiting the MEK-ERK-p90RSK axis. Furthermore, we found that a high-fat diet (HFD) led to adiponectin deficiency and microscopic BPH in a mouse model of obesity. And an adiponectin supplement protected the obese mice from microscopic BPH. The present study provides evidence that adiponectin is a protective regulator in the development and progression of BPH and that adiponectin deficiency causally links BPH with obesity.

Abstract
INTRODUCTION The etiology of benign prostatic hyperplasia (BPH) remains a mystery to scientists; estrogen/androgen imbalance in aged men has been implicated. METHODS Thirty (30) apparently healthy men and newly diagnosed BPH patients were recruited from the Ghana Police Hospital. Lower urinary tract syndrome (LUTS) and prostate volume were assessed via the prostate symptom score sheet (IPSS) and abdominopelvic scan, respectively. Laboratory assays for total prostate specific antigen (tPSA) and hormones [androstenedione (AED), testosterone (T), dihydrotestosterone (DHT), androstanedioladiol (3α-adiol), androstanediol (3β-diol), estrone (E1) and estradiol (E2)] were performed via ELISA techniques. Non-parametric analyses were employed. p < 0.05 was considered significant. RESULTS AED was significantly higher in controls compared to the BPH patients. AKRIC2 (3α-diol/DHT) was significantly higher in the BPH group (p < 0.001) whiles AKRIC1 (3β-diol/DHT) was significantly lower. Estradiol was significantly higher in BPH (p= 0.029). Age correlated negatively with T, while a negative correlation was observed between TIPSS and 3β-diol and AKRIC1. Also, prostate volume correlated negatively with fT.tPSA correlated positively with E2 and aromatase activity (E2/T) and negatively with fT. On multiple linear regression, DHT and 3β-diol remained independent predictors for TIPSS and fT for tPSA. CONCLUSION Estrogens and androstanediols seem to play a role in BPH development.

Abstract
Autophagy is a conserved evolutionary process that allows cells to maintain macromolecular synthesis and energy homeostasis during starvation and stressful conditions. We prospectively evaluated the relationship between autophagy and prostatic inflammation in a series of transurethral prostatic resection samples. Inflammatory infiltrates were defined according to the standardized classification of chronic prostatitis of the National Institute of Health. The inflammatory score (IS score) was calculated. High IS score was defined as ≥7. Each sample was stained for anti-LC3B and for anti-P62/SQSTM1 and scored. High p62 or LC3B percentage was defined as >25%, whereas low was defined as <25% of cells with dots. We analyzed 94 specimens. Overall, 18/94 (19%) showed no sign of prostatic inflammation, whereas 76/94 (81%) presented inflammatory infiltrates. Inflammation was mild in 61/76 (80%), moderate/severe in 15/76 (20%). Patients with high p62 percentage were 62/94 (66%) while 32 (34%) showed low p62 percentage. Patients with high LC3B percentage were 37/94 (39%) while 57(61%) showed low LC3B percentage. Overall 42/94 (44%) patients presented a high p62 percentage and concomitant a low LC3B percentage. IS score was significantly higher in patients with a with high p62 percentage (median IS 7 (6/8) vs 5 (3/7); p= 0.04) and in patients with a low LC3B percentage (median IS 7 (6/8) vs 5 (3/7); p= 0.004) when compared to patients with a low p62 percentage or a high LC3B percentage respectively. On multivariate analysis, p62 (OR: 10.1, 95%CI: 2.6-38.6; p= 0,001) and LC3B expression (OR: 0.319; 95%CI: 0.112-0.907; p= 0.032) were independent predictors of a high IS. Here we present the first evidence of autophagy deregulation in prostatic inflammation. These results raise many questions about the mechanisms mediating the autophagy dysfunction and the links to prostatic inflammation that need to be addressed.

Abstract
The incidence of benign prostatic hyperplasia (BPH) is gradually on the increase. While conventional drugs such as the α1-adrenergic receptor antagonists and 5α-reductase inhibitors have been found to be useful in the treatment of BPH, the adverse side effects associated with their usage, have led to increased search for alternative means of managing this disease. Furthermore, although surgery has also been suggested to be a sure method, the cost and risks associated with it excludes it as a routine treatment. Dietary polyphenols have gained public interest in recent times due to their roles in the prevention of various diseases that implicate free radicals/reactive oxygen species. However, their roles in the management of BPH have not been explored. Hence, this review on their prospects in the management of BPH and their mechanisms of action. Literature search was carried out in several electronic data bases such as PubMed, Google Scholar, Medline, Agora, and Hinari from1970 to 2017 to identify the current status of knowledge on this concept. The findings from these data bases suggest that while dietary polyphenols may not replace the need for the existing therapies in the management of BPH, they hold promise in BPH management which could be explored by researchers working in this field.

Abstract
Background Phytotherapy is a popular treatment option in cases of benign prostatic hyperplasia (BPH), with many different herbal products being used for the treatment of this condition. Withania coagulans (WC) is an herbal medicine that has shown anti-tumoral, anti-inflammatory, and antioxidant effects. Objectives This study examined the effect of Withania coagulans extract (WCE) on prostatic cell apoptosis and cyclooxygenase-2 (COX-2) expression in cases of benign prostatic hyperplasia (BPH) in rats. Methods Forty Wistar rats were equally divided into five groups: control, sham, BPH, BPH + WCE, and BPH + CLX (celecoxib) as a positive control group. The induction of BPH was achieved via the subcutaneous injection of 3 mg/kg of testosterone propionate (TP) daily for 28 days. The animals received WCE, celecoxib, or distilled water by oral gavage accompanied by the TP injection. After four weeks, the prostate glands of the rats were weighed to measure the prostatic index (PI). The ventral lobes of the prostates were dissected and processed with paraffin blocks in order to study the number of mast cells. A TUNEL analysis was performed to evaluate the cell apoptosis, while the expression of COX-2 was examined using immunohistochemistry. Results BPH was obvious in the ventral lobe of the prostate, and the administration of WCE markedly decreased the PI and the number of mast cells (P < 0.001) in the BPH rats. Additionally, the WCE treatment induced prostatic cell apoptosis when compared to the BPH group. Furthermore, following the WCE treatment, the expression of COX-2 in the prostatic tissues was significantly decreased when compared to the BPH groups. Conclusions According to the results of this study, WCE was effective in the treatment of BPH in rats. It may therefore have beneficial effects in the treatment of patients with BPH.

Abstract
Even though rice hull has various physiological functions with high antioxidant potential, the molecular mechanism(s) underlying the effects of rice hull on benign prostatic hyperplasia (BPH) have not been evaluated. The aim of this study was to determine the protective effect of rice hull water extract (RHE) against BPH, which is a common disorder in elderly men and involves inflammation that induces an imbalance between cell proliferation and cell death. In this study, RHE-treated mice exhibited lower prostate weights and ratios of prostate weight to body weight compared to those for the BPH-induced group. In addition, RHE-treated mice had lower serum levels of dihydrotestosterone, mRNA expression of 5α-reductase2, and protein expressions of proliferating cell nuclear antigen (PCNA). Furthermore, RHE treatment significantly decreased cell proliferation by regulating the expression levels of inflammatory-related proteins (iNOS and COX-2) and apoptosis-associated proteins (Fas, FADD, procaspase-8, -3, and Bcl-2 family proteins). These results suggest that RHE could protect against the development of BPH through its anti-inflammatory and apoptotic properties and has good potential as a treatment for BPH.

Abstract
BACKGROUND To investigate the relationship between age, prostate specific antigen (PSA), and prostate volume (PV) in Indonesian men with histologically proven benign prostatic hyperplasia. METHODS Data were generated from our BPH database from June 1994 until December 2013. Subjects were men with a minimum age of 40 years with chief complaint of LUTS or urinary retention, diagnosed with BPH. All patients underwent TRUS-guided prostate biopsy. Patients with PSA level >10 ng/mL were excluded from the study to exclude the possibility of occult prostate cancer. PV was measured with TRUS. Appropriate statistical tests were employed for data analysis. RESULTS In all, 1638 patients were enrolled in our study. There was a statistically significant difference in PSA (P = 0.03) and PV (P < 0.0001) between age groups. Overall correlation between age, PSA, and PV were: i). Age and PV (r = 0.12, P < 0.0001); ii). Age and PSA (r = 0.07, P = 0.008); iii). PSA and PV (r = 0.26, P < 0.0001). Subgroup analysis in terms of indwelling catheter use versus without: i). Age 66.09 ± 8 years versus 65.38 ± 7.66 years (P = 0.158); ii). PSA 4.93 ± 2.62 ng/mL versus 4.68 ± 2.82 ng/mL (P = 0.038); iii). PV 47.58 ± 21.33 mL versus 41.43 ± 20.55 mL (P < 0.0001). Correlation between age, PSA, and PV in patients were similar in patients with and without indwelling catheter. CONCLUSION In Indonesian men with biopsy-proven BPH, both PV and PSA increased with ageing. Prostate volume was significantly correlated with PSA. Even though the results were weaker, these results are consistent with results in other sets of population. The results vary between different countries and thus, ethnicities. Indonesia is a populous a sociocultural and ethnically diverse country. Therefore, aside from PSA, age, and PV, when investigating men with BPH, ethnicity may also need to be taken into account.

Abstract
OBJECTIVES To characterize the molecular features of benign prostatic hyperplasia by carrying out a gene expression profiling analysis in a rat model. METHODS Fetal urogenital sinus isolated from 20-day-old male rat embryo was implanted into a pubertal male rat ventral prostate. The implanted urogenital sinus grew time-dependently, and the pathological findings at 3 weeks after implantation showed epithelial hyperplasia as well as stromal hyperplasia. Whole-genome oligonucleotide microarray analysis utilizing approximately 30 000 oligonucleotide probes was carried out using prostate specimens during the prostate growth process (3 weeks after implantation). RESULTS Microarray analyses showed 926 upregulated (>2-fold change, P < 0.01) and 3217 downregulated genes (<0.5-fold change, P < 0.01) in benign prostatic hyperplasia specimens compared with normal prostate. Gene ontology analyses of upregulated genes showed predominant genetic themes of involvement in development (162 genes, P = 2.01 × 10(-4) ), response to stimulus (163 genes, P = 7.37 × 10(-13) ) and growth (32 genes, P = 1.93 × 10(-5) ). When we used both normal prostate and non-transplanted urogenital sinuses as controls to identify benign prostatic hyperplasia-specific genes, 507 and 406 genes were upregulated and downregulated, respectively. Functional network and pathway analyses showed that genes associated with apoptosis modulation by heat shock protein 70, interleukin-1, interleukin-2 and interleukin-5 signaling pathways, KIT signaling pathway, and secretin-like G-protein-coupled receptors, class B, were relatively activated during the growth process in the benign prostatic hyperplasia specimens. In contrast, genes associated with cholesterol biosynthesis were relatively inactivated. CONCLUSION Our microarray analyses of the benign prostatic hyperplasia model rat might aid in clarifying the molecular mechanism of benign prostatic hyperplasia progression, and identifying molecular targets for benign prostatic hyperplasia treatment.

Abstract
OBJECTIVE To evaluate the association between prostate inflammation, metabolic syndrome (MetS), and postoperative lower urinary tract symptoms in patients treated with transurethral resection of the prostate (TURP). METHODS From April 2011, a consecutive series of patients treated with TURP were prospectively included in this observational study. MetS was defined according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII) criteria. Patients were evaluated at baseline and 1 month postoperative with the International Prostate Symptom Score (IPSS), including the storage IPSS (sIPSS) and voiding IPSS (vIPSS) subscores, the Overactive Bladder questionnaire (OAB-q), and uroflowmetry. Prostate volume was evaluated at baseline. Complications were classified using the modified Clavien system. TURP specimens were examined to define grade, location, and extent of the inflammatory infiltrate according to the standardized classification system of chronic prostatitis and/or chronic pelvic pain syndrome. RESULTS One hundred and thirty-one subjects were enrolled, in which 54 patients (41.3%) presented with MetS. No differences were observed in terms of preoperative prostate-specific antigen, OAB score, IPSS, vIPSS, sIPSS, Qmax, post void residual, and prostate volume in subjects with and without MetS. An incidence of postoperative complications of 10.6% was recorded: 79% were classified as Clavien type I or II; 21% Clavien IIIb. Of 131 subjects, 97 (74.1%) presented with an inflammatory infiltrate. Patients with MetS presented a high proportion of inflammatory infiltrates compared to patients without MetS (45 of 54; 83% vs 52 of 77; 67%, P = .01). Patients with prostate inflammation presented a 50% risk reduction of postoperative storage urinary symptoms. CONCLUSION We confirmed the association between MetS and prostate inflammation.Patients with inflammatory infiltrates mostly benefit from TURP, particularly regarding storage symptoms.

Abstract
BACKGROUND Quantitative analysis of the number, normal and pathologic ratios between lymphocytes and epithelial cells (ECs), and the significance of intraepithelial lymphocytes (IELs) in normal prostatic epithelium, benign prostatic hyperplasia (BPH), and high grade prostatic intraepithelial neoplasia (PIN) in relation to NIH category IV prostatitis (histologic prostatitis: HP) was studied in autopsy prostate. METHODS IELs were analysed in 59 autopsy prostates, which was routinely embedded in paraffin and immunohistochemically stained for CD3. An average of 300-500 ECs were counted per case. The number of IELs was calculated as the mean/100 ECs. Category IV prostatitis was evaluated using NIH consensus grading system in terms of anatomical localization and grade. RESULTS In healthy individuals the mean number of IELs/100 ECs was 0.61 ± 0.34% or ≤1 lymphocyte/100 ECs, which is considered as the normal basal level of prostate IELs. In category IV prostatitis, the mean number of IELs/100 ECs was 8.53 ± 3.25% or 5-11 lymphocytes/100 ECs. The number of IELs in both around and inside inflammation areas correlated to the grade and location of HP (P < 0.0001 and P < 0.0003), the presence of acute glandular inflammation (P < 0.0001), the scattered stromal lymphocytes (P = 0.029), and BPH and PIN associated prostatic inflammation (P < 0.0001). CONCLUSION The study presents the first attempt to examine and score the basic quantitative values of prostatic IELs in normal prostate and in relation to category IV prostatitis. The detected normal upper limit of CD3+ IELs is 1 lymphocyte/100 ECs in the normal prostate epithelium. This is considered as an organ specific characteristic of the prostate-associated lymphoid tissue (PALT). Values >5 IELs/100 ECs indicate the presence of category IV prostatitis. The severity of inflammation correlates to the number of IELs. There is an intimate link between the quantity of the IELs, the degree of the severity and the localization of category IV prostatitis. HP is a chronic and dynamic inflammatory process affecting the whole prostate gland. The increased number of IELs suggests the immune or autoimmune character of category IV prostatitis, BPH and inflammatory preneoplastic (PIN) lesions in the prostatic tumor environment.
