Occurrence Of Benign Prostatic Hyperplasia Research Articles

RELATIONSHIP BETWEEN BENIGN PROSTATIC HYPERPLASIA AND METABOLIC SYNDROME

Introduction: Factors that may increase the risk of Benign Prostatic Hyperplasia (BPH), and one theory suggests a possible connection between metabolic syndrome and the development of BPH. This study aims to investigate the potential relationship between metabolic syndrome and the development of BPH. Methods: This study analyzed medical records from Saiful Anwar Hospital in Malang from 2015 to 2020, using a case-control research design. It applied Chi-Square and Logistic Regression methods for data analysis. Results: The study, based on data from 90 patients, found that the highest number of BPH cases (75.56%) occurred in those with hypertension. Factors like body mass index and blood pressure were significantly associated with BPH (p-values = 0.046; OR = 2.473). Logistic regression confirmed the impact of fasting blood glucose, blood pressure, and body mass index categories on BPH. Conclusion: This research illustrates that there is an association between type 2 diabetes, hypertension, and obesity with the occurrence of BPH. However, there is no statistically significant relationship between the components of metabolic syndrome and the occurrence of BPH.

The Effects of High Fat Diet on the Incidence of Obesity and Monocyte Chemoattractant Protein-1 Levels on Histological Changes in Prostate Wistar Rats.

Benign prostatic hyperplasia (BPH) is a histopathological diagnosis characterized by the increase in stromal cells and epithelial cells of the prostate gland in the transitional zone surrounding the urethra. Obesity is the risk factor of BPH. The most frequent cause of obesity is a high-fat diet (HFD). Obesity and HFD lead to pro-inflammatory conditions. One of the pathomechanisms for the occurrence of BPH is a low-degree inflammatory factor, one of which is the level of monocyte chemoattractant protein-1/MCP-1. This study aims to determine the influence of HFD on the incidence of obesity and inflammatory factors (monocyte chemoattractant protein-1/MCP-1 levels) on the histopathological picture of the prostate. Experimental research was performed on male Wistar rats with each of the 6 rats given normal fat (ND) and HFD intake and terminated at 8 weeks and 6 rats given each ND and HFD were terminated at 16 weeks. The determination of obesity was determined based on Lee's criteria which were categorized as obese if the Lee index >0.3 and non-obese if ≤0.3. Examination of circulating MCP-1 was carried out by the ELISA method and determination of prostatic hyperplasia was done by calculating the percentage of prostate glands that had a large per-field cystic dilatation on light microscopy examination. All data are analyzed statistically with the Fisher Exact Test and Spearman Correlation Test. Of the 12 rats that were given ND, none of them became obese according to Lee's criteria, on the other hand, of the 12 rats that were given HFD 8 became obese (66.7%, p = 0.001). Serum MCP-1 levels and the percentage of prostate glands that had cystic dilatation were significantly higher in mice receiving HFD than ND; both at week-8 (MCP-1; 18.87 vs 15.66) and (prostate gland experiencing cystic dilatation; 63.46% vs 47.24%) and week-16 (MCP-1; 21.27 vs 21.27) and (prostate gland experiencing cystic dilatation; 67.79% vs 56.39%). Spearman correlation analysis showed that only circulating MCP-1 levels were significantly correlated (p < 0.05) to the percentage of the prostate gland that had cystic dilatation; especially in week 16 (r = 0.713 and p < 0.001). At 8 weeks, it was not statistically significant (r = 0.406 and p = 0.095). High fat intake has been shown to increase the risk of obesity, but obesity does not increase inflammatory status and the incidence of prostate glands with cystic dilatation. On the other hand, high-fat intake increases inflammatory status which in turn causes prostate glands to develop cystic dilatation.

(065) The Impact of Testosterone-Replacement Therapy (TRT) on Benign Prostatic Hyperplasia (BPH) Incidence and Need for Interventions in Hypogonadal Men

Abstract Introduction Investigations on the application of testosterone-replacement therapy (TRT) in hypogonadal men with benign prostatic hyperplasia (BPH) show contrasting results. While some studies reported increased prostate-related events with TRT, recent evidence suggested that TRT can alleviate BPH symptoms in hypogonadal men. Objective Our main objective was to determine the impact of TRT on BPH incidence in a large cohort of hypogonadal men. We also evaluated the relationship between TRT in hypogonadal men and the need for BPH interventions. Methods This retrospective case-control study used the 2011-2020 IBM MarketScan database to identify males above 18 years old with a hypogonadism diagnosis, and determine if they received TRT. We used ICD-9, -10, CPT, HCPCS, and NDC codes to identify diagnoses, interventions, and medications. We excluded individuals who were diagnosed with congenital genetic disorders (e.g. chromosomal abnormalities), hypothalamic-pituitary disorders, or prostatic adenocarcinoma. BPH diagnosis was the primary outcome of this study, and BPH treatment was the secondary outcome. We ran cox proportional hazard (CPH) models from initial hypogonadism diagnosis to BPH occurrence to investigate the effect of TRT on the development of BPH. We also used CPH models from time of BPH diagnosis to first intervention, to evaluate the impact of TRT on BPH interventions. In all models we controlled for age, geographic region, population density, and comorbidities. We included TRT within the last 6 as a time-varying covariate in the models. For BPH occurrence there was non-proportionality in the effect of TRT. Thus, we ran two CPH models for BPH occurrence, one from first hypogonadism diagnosis to 912 days (2.5 years), and one from 2.5 years to the end of enrollment. Results In our total cohort of 882570 hypogonadal men, 157185 (17.8%) were diagnosed with BPH. Hyperlipidemia was the most common comorbidity detected in 84% and 68% of hypogonadal men with and without BPH respectively. For the first 2.5 years after hypogonadism diagnosis, there was no significant difference for development of BPH between patients on TRT and those who were not on TRT (HR 1.00, 95%CI 0.98-1.01, p=0.66). However, from 2.5 years onward, men who were on TRT had a 32% greater chance for development of BPH (HR 1.32, 95%CI 1.28-1.36, p&amp;lt;0.001). Hypogonadal men with BPH who received TRT showed no significant difference for BPH interventions compared to those who were not on TRT (HR 0.95, 95%CI 0.89-1, p=0.08). Conclusions In the long term, TRT can increase the risk of development of BPH in hypogonadal men. On the other hand, TRT in hypogonadal men with BPH does not change the need for BPH interventions. Our findings indicate that TRT should be used with caution in hypogonadal men who are at risk of developing BPH but further work is needed to clarify this relationship.

Genetically elevated bioavailable testosterone level was associated with the occurrence of benign prostatic hyperplasia.

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. 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. 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]. 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.

The role of phytoandrogens for benign prostatic hyperplasia treatment

Benign prostatic hyperplasia (BPH) is a common urological condition in aging men. High levels of androgens, including testosterone (T) and dihydrotestosterone (DHT), are closely associated with BPH occurrence and development. Currently, the main clinical drugs used for BPH treatment are 5α-reductase inhibitors and α-receptor blockers, both of which aim to decrease abnormal androgenic signaling while having several unignored side effects. Recently, various natural herbs, such as tonifying yang traditional Chinese medicine (TCM), have been found to have androgenic activities, some of which are also effective for BPH treatment. Here, we review the androgenic activities of phytoandrogens, together with their therapeutic effects in BPH, and summarize the mechanisms involved, providing evidence that such herbs serve as selective androgen receptor modulators.

Comparison of the predictive value of anthropometric indicators for the risk of benign prostatic hyperplasia in southern China.

This study aimed to compare the predictive value of six selected anthropometric indicators for benign prostatic hyperplasia (BPH). Males over 50 years of age who underwent health examinations at the Health Management Center of the Second Xiangya Hospital, Central South University (Changsha, China) from June to December 2020 were enrolled in this study. The characteristic data were collected, including basic anthropometric indices, lipid parameters, six anthropometric indicators, prostate-specific antigen, and total prostate volume. The odds ratios (ORs) with 95% confidence intervals (95% CIs) for all anthropometric parameters and BPH were calculated using binary logistic regression. To assess the diagnostic capability of each indicator for BPH and identify the appropriate cutoff values, receiver operating characteristic (ROC) curves and the related areas under the curves (AUCs) were utilized. All six indicators had diagnostic value for BPH (all P ≤ 0.001). The visceral adiposity index (VAI; AUC: 0.797, 95% CI: 0.759-0.834) had the highest AUC and therefore the highest diagnostic value. This was followed by the cardiometabolic index (CMI; AUC: 0.792, 95% CI: 0.753-0.831), lipid accumulation product (LAP; AUC: 0.766, 95% CI: 0.723-0.809), waist-to-hip ratio (WHR; AUC: 0.660, 95% CI: 0.609-0.712), waist-to-height ratio (WHtR; AUC: 0.639, 95% CI: 0.587-0.691), and body mass index (BMI; AUC: 0.592, 95% CI: 0.540-0.643). The sensitivity of CMI was the highest (92.1%), and WHtR had the highest specificity of 94.1%. CMI consistently showed the highest OR in the binary logistic regression analysis. BMI, WHtR, WHR, VAI, CMI, and LAP all influence the occurrence of BPH in middle-aged and older men (all P ≤ 0.001), and CMI is the best predictor of BPH.

Decoding ceRNA regulatory network and autophagy-related genes in benign prostatic hyperplasia

Benign prostatic hyperplasia (BPH) is a common disease among aging males. We obtained BPH transcriptional signatures by high-throughput RNA sequencing analysis. Accordingly, we determined the differentially expressed RNAs (DERNAs) between BPH tissues and normal prostate tissues. WebGestalt and R package (clusterprofiler) was used to enrichment analysis. Clinical correlations were analyzed using Spearman's coefficient. TargetScan, ENCORI, miRNet, and miRDB databases were used to predict targets' relationships in ceRNA networks. Immunofluorescence staining and qRT-PCR analyses were performed to validate the findings. Microarray analysis of the datasets showed 369 DElncRNAs, 122 DEpseudogenes, 6 DEmiRNAs and 1358 DEmRNAs. DEmRNAs were particularly enriched in the autophagy-related pathways. Following the screening of DEmRNAs and autophagy-related genes (ARGs), 50 DEARGs were selected. MCODE analysis on Cytoscape was performed for the 50 DEARGs, and 3 hub genes (ATF4, XBP1, and PPP1R15A) were obtained. Spearman's correlation analysis showed that the mRNA expression of XBP1 correlated positively with age, total score, and storage score, but negatively with the maximum flow rate. Subsequently, the pseudogene/lncRNA- hsa-miR-222-3p-XBP1 pathway was identified. Our findings elucidate that the pseudogene/lncRNA-hsa-miR-222-3p-XBP1 pathway may play a regulatory role in the occurrence of BPH through autophagy.

Heat Shock Proteins in Benign Prostatic Hyperplasia and Prostate Cancer.

Two out of three diseases of the prostate gland affect aging men worldwide. Benign prostatic hyperplasia (BPH) is a noncancerous enlargement affecting millions of men. Prostate cancer (PCa) in turn is the second leading cause of cancer death. The factors influencing the occurrence of BPH and PCa are different; however, in the course of these two diseases, the overexpression of heat shock proteins is observed. Heat shock proteins (HSPs), chaperone proteins, are known to be one of the main proteins playing a role in maintaining cell homeostasis. HSPs take part in the process of the proper folding of newly formed proteins, and participate in the renaturation of damaged proteins. In addition, they are involved in the transport of specific proteins to the appropriate cell organelles and directing damaged proteins to proteasomes or lysosomes. Their function is to protect the proteins against degradation factors that are produced during cellular stress. HSPs are also involved in modulating the immune response and the process of apoptosis. One well-known factor affecting HSPs is the androgen receptor (AR)—a main player involved in the development of BPH and the progression of prostate cancer. HSPs play a cytoprotective role and determine the survival of cancer cells. These chaperones are often upregulated in malignancies and play an indispensable role in tumor progression. Therefore, HSPs are considered as one of the therapeutic targets in anti-cancer therapies. In this review article, we discuss the role of different HSPs in prostate diseases, and their potential as therapeutic targets.

Effects of Saussurea costus on apoptosis imbalance and inflammation in benign prostatic hyperplasia

Ethnopharmacological relevanceSaussurea costus (synonym: Aucklandia lappa Decne) is a medicinal plant distributed in Yunnan, Guangxi, and Sichuan in China. In traditional Korean medicine, the plant parts (especially the root—“radix aucklandiae”) is widely used to treat vomiting, diarrhea, and inflammation. However, little has been reported on its effect on benign prostatic hyperplasia (BPH), which is common in middle-aged men. Aim of the studyBPH is caused by apoptosis imbalance and inflammation due to aging of the prostate. Therefore, the aim of this was to prove the efficacy of S. costus by analyzing its effect on the biological mechanisms leading to BPH progression. Materials and methodsWistar rats were injected subcutaneously with a single dose of testosterone (125 mg/kg) to induce BPH, and were later administered with S. costus (20, 40 mg/kg). After 12 weeks, histological changes in the prostate and hormone regulation factors were assessed in all animals. Furthermore, apoptotic protein and apoptotic body values were analyzed to confirm the improvement of apoptosis imbalance, and inflammatory cytokines were analyzed to confirm the anti-inflammatory efficacy of S. costus. ResultsIn the serum and tissue of S. costus-treated BPH rats, a significant reduction in prostate weight, prostate index, and hormone regulation factors was observed. S. costus also increased the levels of apoptosis marker proteins and reduced the levels of inflammatory cytokines. It also decreased the expression of B-cell lymphoma 2 (BCL-2) and increased the expression of BCL-2 associated X protein (BAX) in the prostate. Histological changes such as epithelial thickness significantly increased in BPH induced group but significantly decreased in the S. costus-treated groups (p < 0.001). ConclusionsS. costus may prevent and treat BPH occurrence by modulating inflammation and apoptosis imbalance.

Pulsed-wave Doppler Ultrasound in canine reproductive system – Part 2: use in the routine

Given the importance of the reproduction field combined with the use of the Pulsed-Wave (PW) ultrasound in the clinical routine, this study aims to review the application of this diagnostic method in the reproductive tract of females and males of the canine species. A narrative review was carried out by using scientific articles, monographs, dissertations and thesis published and available in online databases: Periodical Capes (Coordination for the Improvement of Higher Education Personnel), SciELO (Scientific Electronic Library Online) and Google Scholar, in addition to specific books on the topic. In female dogs, Doppler ultrasound can be used to evaluate hemodynamic conditions in the estrous cycle (e.g. estimating day of ovulation and fertility, diagnosing early pregnancy, abnormalities, and fetal stress, thus ensuring greater obstetric safety) and identification of diseases, thereby avoiding unnecessary surgical interventions. In male dogs, however, Doppler ultrasound is mainly used in vascular evaluations in order to identify hemodynamic changes due to occurrence of benign prostatic hyperplasia (BPH), most common disease of the prostate and in the assessment of testicular arteries to better understand spermatogenesis and diseases that affect the testicle. In this review, we demonstrate that the use of Doppler mode ultrasound, especially the PW, allows dynamic analysis in clinical examination and complements important information in the diagnosis and treatment of different reproductive disorders in dogs.

Dynamics of morbidity and risk factors affecting the quality of life of patients with benign prostatic hyperplasia

The article discusses the dynamics of morbidity and risk factors that influence the occurrence of benign prostatic hyperplasia (BPH). An increase in the number of diseases of the genitourinary system, among which prostate diseases account for about 25%, is an important medical and social problem, as the symptoms of BPH significantly reduce the quality of life of men. The main parameters of the quality of life of patients with BPH include not only the severity of the signs of the disease, but also the mental well-being and self-awareness of physiological and psychological well-being. Early diagnosis and elimination of risk factors for the development of BPH makes it possible to start timely treatment. Among surgical approaches, transurethral methods are currently the most common: transurethral resection, transurethral enucleation with a bipolar loop and bipolar vaporesection of prostate.

Old Rats Are More Susceptible to Induction of Benign Prostatic Hyperplasia (BPH) at Comparative to Young Mature.

The aim of the experiments was to find out the factors on which age-related sensitivity to the occurrence of BPH depends. 45 Male Wistar rats aged 3 and 24 months were used. In each age group, there were intact rats and animals with induced BPH (by surgical castration + testosterone injections, 25 mg/kg x 7). On the 36th day of the experiment, blood was taken from rats to determine serum testosterone, cholesterol, triglycerides and glucose; then, the animals were autopsied, their prostates were weighed, and their morphology was studied. Young mature intact rats had much higher testosterone levels (6.2±0.93 nmol/l) than old intact (3.8±0.55 nmol/l), while the ratio of prostate weight was inverse. The weight of the prostate and prostatic index in old rats with induced BPH was significantly higher not only in comparison with the old intact rats but also with young animals after BPH induction. Morphologically, the inflammatory foci were determined not only in the prostates of old rats, which induced BPH, but also in intact animals. Besides, in old intact rats, the foci of prostate hyperplasia were often noted. Our experimental model indicates the important role of non-bacterial prostatitis in the pathogenesis of BPH. No metabolic disorders in BPH induction were revealed. The sensitivity of the prostate of old rats to BPH development is increasing despite the low concentrations of testosterone in the body. Age sensitivity to BPH is probably determined by a higher expression of androgen receptors in old animals.

Patient quality of life and risk factors affecting the development of benign prostatic hyperplasia

The article considers the risk factors affecting the occurrence of benign prostatic hyperplasia (BPH) and the quality of life of patients with this type of pathology. World statistics indicate that BPH is a disease of mainly elderly and senile men. The main reason leading to the development of BPH is a change in the hormonal background of males. BPH is characterized by symptoms that negatively affect the quality of life of men, causing physical and psychological discomfort. This pathology is accompanied by squeezing of the bladder, which contributes to the appearance of frequent urge to empty it, erectile dysfunction, a decrease or complete absence of sexual desire, which often leads to a decrease in self-esteem and depression. Among the main risk factors that cause BPH controllable and uncontrollable ones are distinguished. Elimination of the influence of controllable risk factors that cause BPH leads to a decrease in the rate of progression of the disease, allows timely initiation of treatment, which has a positive effect on the quality of life of men with this diagnosis.

Increased risk of subsequent benign prostatic hyperplasia in non-Helicobacter pylori-infected peptic ulcer patients: a population-based cohort study

The vagus nerve plays an essential role in homeostasis and inflammation. Clinically, peptic ulcer patients without helicobacter pylori (HP) infection may provide a population for studying the effect of vagal hyperactivity. There were interests in the association of gastrointestinal disease and urogenital disorders. Herein, we try to investigate subsequent risk of benign prostatic hyperplasia (BPH) in non-HP infected peptic ulcer patients. We identified 17,672 peptic ulcer admission male patients newly diagnosed in 1998–2007 from Taiwan Health Insurance Database, and 17,672 male comparison without peptic ulcer, frequency matched by age, and index-year. We assessed subsequent incidence of BPH in each cohort by the end of 2013, and then compared the risk of developing BPH between individuals with and without peptic ulcer. In addition, peptic ulcer patients underwent surgery were also examined. There were 2954 peptic ulcer patients and 2291 comparisons noted with the occurrence of BPH (25.35 and 16.70 per 1000 person-years, respectively). Compared to comparisons, peptic ulcer patients had a 1.45- and 1.26-fold BPH risk in multivariable Cox model and Fine and Gray model (95% CI 1.37–1.54 and 1.19–1.34). In age-stratified analysis, the highest risk of BPH was in 45–59 years (interaction p < 0.05). Regarding surgery types, peptic ulcer patients who underwent simple suture surgery (i.e.: with integrated vagus nerve) had a significant higher BPH risk than comparison (HR 1.50 and 95% CI 1.33–1.74; SHR 1.26 and 95% CI 1.07–1.48), while patients underwent truncal vagotomy/pyloroplasty showed a lower incidence of BPH. In this study, non-HP-infected male peptic ulcer patients were found to have an increased risk of subsequent BPH. Indicating that there might be a role of vagus nerve. Based on the limitations of retrospective nature, further studies are required.

In Silico and In Vitro Study: COX-2 Inhibition by Ethanol Extract of Dayak Onion Bulb (Eleutherine Americana Merr) as Treatment Innovation of Benign Prostatic Hyperplasia (BPH).

Benign Prostatic Hyperplasia (BPH) is a benign tumor in males, which is histopathologically known with an increase of epithelial cells and prostatic stroma. Androgens, estrogens, stroma-epithelial interactions, growth factors, and chronic inflammation play a key role in the occurrence of BPH. Chronic inflammation in BPH is characterized by excessive expression of COX-2, which will trigger the expression of Bcl-2 anti-apoptotic protein. Dayak onion (Eleutherine Americana Merr) is a typical Kalimantan plant that is known as the treatment for prostate disease. This plant contains flavonoids which can inhibit the COX-2 enzyme thus causing a reduction in the production of prostaglandin E2. This research was experimental research computationally and in vitro laboratory experimental research to determine COX-2 inhibitory activity by ethanol extracts of Dayak onion. In in silico flavonoid, it was strongly related to COX-2 receptor on the active side of TYR371. Thus, it had the potential to inhibit COX-2. COX-2 inhibitor would cause BCL-2 to be inactive so that apoptosis occurr in BPH. In the in vitro research using human whole blood assay, the Dayak Onion bulb ethanol extract had IC50 COX-2 of 40.57 ng/ml and IC50 COX-1 of 364.89 ng/ml. Therefore, the ratio of IC50 COX-2 to IC50 COX-1 was 0.11. Ethanol extract of Dayak onion bulb has an inhibitory activity against COX-2. Thus, it has a potential of being an innovation for BPH treatment. Patient Summary: A healthy male, age 25-35 years old (history taking, physical and laboratory examination), and not using NSAIDs for the past 2 weeks.

Malakoplakia of the prostate diagnosed in patients with benign prostatic hyperplasia and elevated prostate-specific antigen

Malacoplasia é uma doença inflamatória crônica pouco frequente que afeta o aparelho geniturinário, particularmente a bexiga, os rins e os ureteres. O envolvimento isolado da próstata é a forma mais rara. O diagnóstico diferencial do adenocarcinoma da próstata pode ser de extrema dificuldade em virtude das semelhanças clínicas e imaginológicas. Pacientes com hiperplasia benigna de próstata e infecções do trato urinário frequentes podem alertar para o diagnóstico de malacoplasia.

Oxidative stress and prostatic diseases.

Prostatic diseases are a common health problem among males in Western countries, and include chronic prostatic diseases, which have an unclear pathogenesis and few treatment options. In vitro and in vivo studies describe oxidative stress as a major pathway involved in the occurrence of benign prostatic hyperplasia, prostatic cancer and chronic prostatitis. Thus, the oxidative stress cascade is a potential target for the treatment of prostatic diseases. This paper presents a systematic review of the available data concerning the association between oxidative stress and the most common chronic prostatic diseases, and describes the available treatment options that act upon this pathway.

Association between SRD5A2 rs523349 and rs9282858 Polymorphisms and Risk of Benign Prostatic Hyperplasia: A Meta-Analysis.

Objective: Previous studies have reported that rs523349 (V89L) and rs9282858 (A49T) polymorphisms in the gene 5α-reductase II (SRD5A2) are associated with the risk of benign prostatic hyperplasia (BPH), but different opinions have emerged. In view of distinct discrepancies among those findings, we performed this meta-analysis to ascertain a more accurate association between SRD5A2 rs523349 and rs9282858 polymorphisms and the risk of BPH.Methods: Studies investigating the association between SRD5A2 rs523349 and rs9282858 polymorphisms and susceptibility to BPH were searched from the databases of PubMed, Embase, Wanfang, and Chinese National Knowledge Infrastructure (CNKI).The strength of correlation was assessed by crude odds ratios (ORs) with their corresponding 95% confidence intervals (95% CIs). Moreover, subgroup analysis was conducted to further ascertain such relationship and investigate sources of heterogeneity.Results: SRD5A2 rs9282858 (A49T) polymorphism showed a significant correlation with increased BPH susceptibility under allele T vs.allele A genetic model (OR = 2.51, 95% CI = 1.29–4.88) in total analysis, and stratification analysis by ethnicity also revealed a similar association in Caucasian group under the same contrast. SRD5A2 rs523349 (V89L) polymorphism showed no significant role in BPH occurrence in total analysis, but its reducing and increasing effects on the disease risk were reflected in Caucasian and other-ethnicity subgroups, respectively, after stratification analysis by ethnicity.Conclusion: In conclusion, SRD5A2 rs9282858 polymorphism may elevate the susceptibility to BPH, while the polymorphism rs523349 may exert different influences on the disease in people of different ethnic lines.

Prostatitis and Benign Prostatic Hyperplasia among Monks/Friars Aged 45-70 Presented at Unth Enugu state, Nigeria Between 2008-2013

The present work was undertaken to study the prevalence of prostatitis and Benign prostatic Hyperplasia (BPH) among male nuns aged 45-70 years presented at the University of Nigeria Teaching Hospital (UNTH) Ituku/Ozalla, Enugu between 2008-2013. A total of thirty (30) paraffin processed Benign Prostatic Hyperplasia and prostatitis tissue biopsies were used. These samples were obtained by medical experts from patients who had been diagnosed of BPH and prostatitis between the years 2008-2013. Two (2) thin sections (5 μ) were obtained from each paraffin block of BPH and prostatitis and stained with Haematoxylin and Eosin (H&E). The results obtained showed that they were higher prevalence of BPH (62.34%) to prostatitis (37.80%) in UNTH from the year 2008-2013. It was also observed that the occurrence of these diseases is mostly dependent on the age of individual. The increased prevalence rate of 62.24% was seen mostly amongst monks which show significant result (p<0.05) between the ages 51-70 years while the incidence rate of prostatitis in UNTH under the period of study mostly among the monks studied is 37.80% seen among the monks/friar between 45-50 years. Also, the various morphological alterations seen in the examined diseased prostate tissues state included the presence of inflammatory cells, prostatic acini, corpora amalycae, prostatic region, hyperplastic cyst and fibromuscular region. In conclusion, the occurrence of BPH and prostatitis depend on the age of the individual.
