JOURNAL OF ETHNOPHARMACOLOGY 2024; 331:118301. [PMID: 38735419 DOI: 10.1016/j.jep.2024.118301] [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: 12/27/2023] [Revised: 04/18/2024] [Accepted: 05/06/2024] [Indexed: 05/14/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Many ethnopharmacological properties (anti-tumor, etc.) have been credited to Plectranthus esculentus tuber but the scientific basis has not been established. AIM OF THE STUDY To evaluate the effect of methanol extract of P. esculentus tuber (MEPET) (phase 1) and its fractions (phase 2) on benign prostatic hyperplasia (BPH) in rats. MATERIALS AND METHODS The study was conducted in two phases. Phase 1, thirty-five male albino rats (6 weeks old) were divided into seven groups of five rats each: normal control (NC) received olive oil (subcutaneously) and water (orally); disease control (DC) received testosterone propionate (TP) (3 mg/kg) and water; test groups (1,2,3 and 4) received TP + MEPET at 100, 200, 400, 600 mg/kg respectively; positive control, received TP + finasteride (5 mg/70 kg). After 28 days, their relative prostate weights (RPW) and prostate specific antigen (PSA) were determined. Phase 2, thirty rats were divided into 6 groups of 5 rats each: NC received olive oil (subcutaneously daily) and dimethyl sulfoxide (DMSO) (orally); DC received TP (3 mg/kg), and DMSO; test group 1 received TP and aqueous fraction of MEPET (400 mg/kg); test group 2 received TP and methanol fraction of MEPET (400 mg/kg); test group 3 received TP, and ethyl acetate fraction of MEPET (400 mg/kg); positive control received TP and finasteride (5 mg/70 kg). After 28 days, their erythrocyte sedimentation rates, RPW, prostate levels of PSA, DHT, inflammatory, apoptotic markers and prostate histology were determined. RESULTS Ethyl acetate fraction of MEPET modulated most of the parameters of BPH in the rats in a manner akin to finasteride as corroborated by prostate histology. CONCLUSIONS EFPET could be useful in the treatment of BPH.

Abstract
AIMS Lower urinary tract symptoms (LUTS) persist in up to 50% of patients after bladder outflow resistance reduction surgery (BORRS) in men. Our think tank aims to address the predictive factors for persistent LUTS after BORRS and to propose the recommendations for future research to enable improved better patient counseling and selection by more accurate prediction of treatment outcome. METHODS A think tank of ICI-RS gathered in 2023, Bristol, UK, to discuss the pre and postsurgical clinical and urodynamic evaluation of men undergoing BORRS and whether it is possible to predict which men will have persistent LUTS after BORRS. RESULTS Our think tank agrees that due to the multifactorial, and still not fully understood, etiology of male LUTS it is not possible to precisely predict in many men who will have persistent LUTS after BORRS. However, severe storage symptoms (overactive bladder, OAB) in association with low volume and high amplitude detrusor overactivity and low bladder capacity in preoperative urodynamics, increase the likelihood of persistent OAB/storage symptoms after BORRS. Furthermore, patients who are clearly obstructed and have good bladder contractility on preoperative pressure flow studies do better postoperatively compared to their counterparts. However, the benefit of pressure flow studies is decreased in patients who do not acceptably void during the study. Poor voiding after BORRS may occur due to persistent obstruction or detrusor underactivity. CONCLUSION Future research is needed to increase our understanding of why male LUTS persist after surgery, and to enable better patient selection and more precise patient counseling before BORRS.

Development and validation of a clinical nomogram to predict prostatic inflammation in men with lower urinary tract symptoms. Prostate Cancer Prostatic Dis 2024:10.1038/s41391-024-00857-5. [PMID: 38971935 DOI: 10.1038/s41391-024-00857-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 05/30/2024] [Accepted: 06/06/2024] [Indexed: 07/08/2024]
Abstract
BACKGROUND Prostatic inflammation is an important etiological component of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). The Prostatic Inflammation Nomogram Study (PINS) aimed to develop and validate a nomogram for predicting the presence of prostatic inflammation in men with LUTS. METHODS This non-interventional, cross-sectional, prospective study was conducted in six secondary/tertiary centers across Cyprus, Greece, Italy, Portugal, and Spain. Men (≥40 years) with BPH/LUTS scheduled to undergo prostatic surgery or transrectal ultrasound-guided (TRUS) prostate biopsy were included. Fifteen demographic and clinical participant characteristics were selected as possible predictors of prostatic inflammation. The presence of inflammation (according to Irani score) in the prostatic tissue samples obtained from surgery/TRUS biopsy was determined. The effect of each characteristic on the likelihood a prostate specimen demonstrated inflammation (classified by Irani score into two categories, 0-2 [no/minimal inflammation] or 3-6 [moderate/severe inflammation]) was assessed using multiple logistic regression. A nomogram was developed and its discriminatory ability and validity were assessed. RESULTS In total, 423 patients (mean age 68.9 years) were recruited. Prostate volume ultrasound (PVUS) > 50 mL, history of urinary tract infection (UTI) treatment, presence of diabetes, and International Prostate Symptom Score (IPPS) Storage score were statistically significant predictors of Irani classification. Logistic regression demonstrated a statistically significant effect for leucocytes detected via urine dipstick, presence of diabetes, PVUS > 50 mL, history of UTIs, and higher IPSS Storage score for the odds of an inflammatory score category of 3-6 versus 0-2. The nomogram had a concordance index of 0.71, and good internal validity. CONCLUSIONS The nomogram developed from PINS had good predictive ability and identified various characteristics to be predictors of prostatic inflammation. Use of the nomogram may aid in individualizing treatment for LUTS, by identifying individuals who are candidates for therapies targeting prostatic inflammation.

Abstract
Fibrosis is a pathological process involving the abnormal deposition of connective tissue, resulting from improper tissue repair in response to sustained injury caused by hypoxia, infection, or physical damage. It can impact any organ, leading to their dysfunction and eventual failure. Additionally, tissue fibrosis plays an important role in carcinogenesis and the progression of cancer.Early and accurate diagnosis of organ fibrosis, coupled with regular surveillance, is essential for timely disease-modifying interventions, ultimately reducing mortality and enhancing quality of life. While extensive research has already been carried out on the topics of aberrant wound healing and fibrogenesis, we lack a thorough understanding of how their relationship reveals itself through modern imaging techniques.This paper focuses on fibrosis of the genito-urinary system, detailing relevant imaging technologies used for its detection and exploring future directions.

Subchronic intake of arsenic at environmentally relevant concentrations causes histological lesions and oxidative stress in the prostate of adult Wistar rats. Reprod Toxicol 2024; 128:108647. [PMID: 38909693 DOI: 10.1016/j.reprotox.2024.108647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 05/30/2024] [Accepted: 06/15/2024] [Indexed: 06/25/2024]
Abstract
The prostate gland is one of the main sites of hyperplasia and cancer in elderly men. Numerous factors have been demonstrated to disrupt prostate homeostasis, including exposure to environmental pollutants. Arsenic is a metalloid found ubiquitously in soil, air, and water, which favors human poisoning through the involuntary intake of contaminated drinking water and food and has harmful effects by increasing the oxidative stress response. This study aimed to investigate the effects of prolonged exposure to arsenic at environmentally relevant concentrations on the prostate biology of adult Wistar rats. Thirty 80-day-old male rats were divided into three experimental groups. Rats from the control group received filtered water, whereas animals from the arsenic groups ingested 1 mg L-1 and 10 mg L-1 of arsenic, in the form of sodium arsenite, daily. The arsenic solutions were provided ad libitum in the drinking water for eight weeks. Our results showed that 1 mg L-1 and 10 mg L-1 of arsenic made the prostate susceptible to evolving benign and premalignant histopathological changes. While the ingestion of 1 mg L-1 of arsenic reduced SOD activity only, 10 mg L-1 diminished SOD and CAT activity in the prostate tissue, culminating in high MDA production. These doses, however, did not affect the intraprostatic levels of DHT and estradiol. In conclusion, exposure to arsenic at environmentally relevant concentrations through drinking water induces histological and oxidative stress-related changes in the prostate of adult rats, strengthening the between arsenic exposure and prostate disorders.

Abstract
Discovering the balance between toxicity and efficacy for many drugs requires therapeutic drug monitoring (TDM) of their concentrations in the blood. Here, a hot-embossed microfluidic device with a new design integrated to a nanofracture is presented for purification of blood samples from numerous proteins and cells, allowing to the separation of small molecules from blood matrix. The device was used to separate and quantitatively detect tamsulosin drug after derivatization with fluorescamine reagent, allowing converting it from a neutral molecule into a charged fluorescent complex under the experimental conditions, and thus its separation by electrophoresis. The device is portable and easy operated, and the presented method showed good linearity (R2 = 0.9948) over a concentration range of 0.1-1 μg/mL. The relative standard deviation (RSD%) was below 10% (n = 3), indicating good precisions, and the limit of detection (LOD) and limit of quantitation (LOQ) values were estimated to be 0.1 and 0.55 μg/mL, respectively. Whole blood samples from 10 patients with benign prostatic hyperplasia (BPH) were analyzed, showing good percentage recoveries of tamsulosin in whole blood. This point-of-care (POC), low-cost method could increase the convenience of patients and doctors, make therapies safer, and make TDM available in different regions and places.

Abstract
PURPOSE Aim of the study was to evaluate the prevalence of LUTS in taxi drivers. METHODS Between February 24th 2021 and March 26th 2021 a web based survey was administered to Taxi drivers in the city of Florence. Taxi drivers were evaluated with baseline characteristics such as: age, BMI, smoking, career length, comorbidities, and treatment. LUTS were evaluated using the international prostate symptom score (IPSS) and the overactive bladder (OAB) score. As well sexual function was evaluated using the international index erectile function (IIEF) and female sexual function index (FSFI) questionnaires. Risk factors for LUTS were evaluated using regression analysis. RESULTS The overall response rate was 64.6% (537/830 taxi drivers filled the questionnaires). Among them, 449 (83.6%) were men and 88 (16.4%) females. Overall, median IPSS was 5 (2/9) and median OAB score was 10 (7/14). On multivariate binary regression analysis age > 50 (OR:1.60; p < 0,05), Smoking (OR:1.57; p < 0,05), chronic treatment (OR:1.57; p < 0,05), recurrent cystitis (OR: 2.66; p < 0,05) and chronic pelvic pain (OR:4.94; p < 0,05) were independent risk factors for moderate/severe LUTS. On multivariate binary logistic regression analysis, risk factors for erectile dysfunction were age older than 50 years (OR = 3.64; p < 0.05) and urinary incontinence (OR = 5.53; p = 0.005). CONCLUSIONS According to our web-based survey, Taxi drivers in the metropolitan city of Florence had non-negligible symptomatic LUTS and even sexual dysfunction. Our data suggest as LUTS are particular influenced by several life-style and behavioural factors as type and duration of work.

Abstract
INTRODUCTION Aims of the study were to investigate the related factors of urinary incontinence after transurethral holmium laser enucleation of the prostate (HoLEP) and to provide guidance for clinical urinary control of HoLEP. METHODS The clinical data of 548 patients who underwent HoLEP were retrospectively analyzed. The patients were followed up for the occurrence of urinary incontinence in the short term (2 weeks), medium term (3 months), and long term (6 months) after HoLEP. RESULTS Among the 548 benign prostatic hyperplasia patients, 79 cases (14.42%) had urinary incontinence at 2 weeks, 19 cases (3.47%) at 3 months, and 2 cases (0.36%) at 6 months after surgery. Logistic regression analysis showed that age, prostate volume, diabetes mellitus, operation time, prostate tissue weight, and histological prostatitis were risk factors for recent urinary incontinence (p < 0.05). Age, diabetes, and operation time were risk factors for mid-term urinary incontinence (p < 0.05). The incidence of long-term urinary incontinence was low and no risk factor analysis was performed. CONCLUSIONS For good urinary control after HoLEP, in addition to surgery-related factors such as surgical skills, proficiency, and precise anatomy, patients' risk factors should also be paid attention to in order to improve postoperative urinary control more effectively and reduce the incidence of urinary incontinence.

Abstract
BACKGROUND Depression is associated with an increased risk of lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). Whether the dynamic nature of depression affects the incidence of LUTS/BPH remains unknown. A four-year cohort study based on the China Health and Retirement Longitudinal Study (CHARLS) was conducted to assess their association. METHODS This study included 3433 Chinese men from the CHARLS 2011, representative of > 95 million individuals. All eligible individuals underwent three assessments of LUTS/BPH and depression in 2011, 2013 and 2015. The dynamic nature of depression was classified as acute depression with remission, acute depression with recurrence, or chronic major depression. Weighted, generalized additive analyses with three binomial models were used to investigate the relationship between LUTS/BPH and the dynamic nature of depression. RESULTS During the four-year follow-up, 11.5% (95% confidence interval [95% CI] = 9.5-13.3%) of Chinese men were diagnosed with newly incident LUTS/BPH. Meanwhile, there were 60.6% (95% CI = 58.5-62.7%) of the individuals without depression and 8.9% (95% CI = 7.9-10%) of the individuals with chronic major depression. A total of 25.1% (95% CI = 23.4-26.9%) and 5.4% (95% CI = 4.6-6.3%) of the individuals were categorized as acute depression with remission and recurrence. After weighted, adjusted all included confounding risk factors, chronic major depression (RR = 1.63, 95% CI = 1.14-2.33, P < 0.01) but not acute depression with remission (RR = 1.2, 95% CI = 0.92-1.56, P = 0.18) and recurrence (RR = 1.32, 95% CI = 0.82-2.10, P = 0.26) significantly increased the incidence of LUTS/BPH compared with no depression. The subgroup analysis showed that the above relationships appeared to be evident among Chinese men < 60 years. CONCLUSIONS Our results suggest that the dynamic nature of depression has a different effect on the incidence of LUTS/BPH. The monitoring and treatment of depression are important in preventing LUTS/BPH.

Lee SM, Lee SM, Song J. Effects of Taraxaci Herba (Dandelion) on Testosterone Propionate-Induced Benign Prostatic Hyperplasia in Rats. Nutrients 2024; 16:1189. [PMID: 38674879 PMCID: PMC11054461 DOI: 10.3390/nu16081189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2024] [Revised: 04/11/2024] [Accepted: 04/15/2024] [Indexed: 04/28/2024] Open
Abstract
Benign prostatic hyperplasia (BPH) is the non-malignant enlargement of the prostate, associated with lower urinary tract symptoms (LUTSs). Taraxaci Herba (TH), commonly known as dandelion, has traditionally been utilized in East Asia to treat symptoms related to LUTSs. Based on this traditional use, our study aimed to explore the inhibitory effects of TH on BPH progression using a testosterone propionate-induced rat model. To induce BPH, male Sprague Dawley rats were castrated and injected subcutaneously with testosterone propionate (3 mg/kg/day) for 28 days. Concurrently, TH extract was administered orally at doses of 100 and 300 mg/kg/day throughout the four-week period of testosterone propionate injections. The TH extract significantly reduced both the absolute and relative weights of the prostate, along with histopathological changes in the gland. Moreover, it lowered serum levels of testosterone and dihydrotestosterone and reduced the expression of the androgen receptor in the prostate. Additionally, the TH extract modulated the protein expressions of Bax and Bcl-2, which are key regulators of apoptosis in prostate cells. Collectively, our findings suggest that TH inhibits BPH development partially by modulating androgen signaling and inducing apoptosis within the prostate.

Awareness and prevalence of self-reported benign prostatic hyperplasia: a cross-sectional study in Saudi Arabia. Front Public Health 2024; 12:1271816. [PMID: 38628856 PMCID: PMC11018881 DOI: 10.3389/fpubh.2024.1271816] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 03/19/2024] [Indexed: 04/19/2024] Open
Abstract
Background Benign prostatic hyperplasia (BPH) is a prevalent condition in older men, causing significant morbidity. Despite recent progress, essential concerns of the disease remain under-researched. This study aims to assess knowledge and estimate self-reported prevalence of BPH in Saudi Arabian men. Understanding BPH prevalence in Saudi Arabia is essential for healthcare planning, resource allocation, public awareness, early detection, intervention, research, and addressing regional variations. Method A cross-sectional study was conducted from February to May 2022 using a validated questionnaire. Univariate and multivariate statistical methods assessed knowledge of BPH among 559 adult Saudi men (mean age: 47.2 years) and its association with demographic variables. Results The self-reported prevalence rate of BPH for Saudi Arabian men was 12.0%. Most adults (74.2%) were aware that BPH is a risk factor for prostate cancer and 75% were aware of the increased risk of BPH in older people. Furthermore, 44.5% of participants associated nocturia with BPH, while 76.6% related urinary tract infection (UTI) with BPH. The study demonstrated a significant association between BPH awareness and marital status (p = 0.02), level of education (p = 0.02), and employment status (p = 0.04). Conclusion While men in Saudi Arabia generally had sufficient knowledge about BPH, there was a knowledge gap regarding certain risk factors like obesity and cardiac diseases. To address this, an educational program should be developed for both the general population and those at high risk of BPH.

Abstract
In men, the lower urinary tract comprises the urinary bladder, urethra, and prostate, and its primary functions include urine storage and voiding. Hypertension is a condition that causes multi-organ damage and an age-dependent condition. Hypertension and the renin-angiotensin system activation are associated with the development of lower urinary tract dysfunction. Hypertensive animal models show bladder dysfunction, urethral dysfunction, and prostatic hyperplasia. In the renin-angiotensin system, angiotensin II and the angiotensin II type 1 receptor, which are expressed in the lower urinary tract, have been implicated in the pathogenesis of lower urinary tract dysfunction. Moreover, among the several antihypertensives, renin-angiotensin system inhibitors have proven effective in human and animal models of lower urinary tract dysfunction. This review aimed to elucidate the hitherto known mechanisms underlying the development of lower urinary tract dysfunction in relation to hypertension and the angiotensin II/angiotensin II type 1 receptor axis and the effect of renin-angiotensin system inhibitors on lower urinary tract dysfunction. Possible mechanisms through which hypertension or activation of Ang II/AT1 receptor axis causes LUTD such as bladder dysfunction, urethral dysfunction, and prostatic hyperplasia. LUT: lower urinary tract, LUTD: lower urinary tract dysfunction, AT1: angiotensin II type 1, ACE: angiotensin-converting enzyme.

Abstract
Objective Erectile dysfunction (ED) is a condition of insufficient penile erection, consistently or recurrently, for sexual activity. Tumor necrosis factor-alpha (TNF-α) induces transforming growth factor-beta (TGF-β), which causes the transition of epithelial cells into mesenchymal cells that affect ED. This study aimed to evaluate the roles of TNF-α, TGF-β, degree of lower urinary tract symptoms, and prostatic volume for the presence of ED in benign prostatic hyperplasia (BPH) patients. Methods Our study performed an analytic observational retrospective cohort study using secondary data from four hospitals in Bali, Indonesia, including medical records and other administrative data. The sample was BPH patients with several history qualifications. Results Our sample was 83 respondents, ranging from 50 years to 80 years, 61 respondents with ED and 22 with non-ED. The International Prostate Symptom Score showed a significant result, which indicates that ED is more common in patients with higher International Prostate Symptom Score (p=0.002). Moreover, the TNF-α of ≥43.9 pg/mg and TGF-β of ≥175.8 pg/mL were significantly associated with the presence of ED in BPH patients (p<0.0001). Despite these results, prostate volume is not significant with ED (p=0.947). Conclusion TNF-α, TGF-β, and lower urinary tract symptoms severity can predict the occurrence of ED in BPH, while prostatic volume was not significant.

Abstract
INTRODUCTION During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, the management of patients with lower urinary tract symptoms (LUTS) underwent dynamic adjustments in response to an evolving understanding of the virus's impact on different patient populations. Healthcare practitioners reevaluated therapeutic approaches for conditions like benign prostatic hyperplasia (BPH), considering the potential implications of this condition on the severity and progression of coronavirus disease 2019 (COVID-19). This study aims to investigate potential correlations between SARS-CoV-2 infection severity, exacerbation of LUTS, and BPH progression. MATERIAL AND METHODS This retrospective study includes patients hospitalized in our Urology Department between January 2021 and January 2023, presenting with both SARS-CoV-2 and BPH. Their ages ranged from 57 to 88 years, with a mean age of 65.4 years. The diagnosis of BPH relied on a diagnostic triad consisting of digital rectal examination, biological markers (including prostate-specific antigen (PSA) and free PSA, and ultrasound examination, with both conditions confirmed based on test results. Transurethral resection of the prostate (TURP) procedures utilized monopolar Karl Storz resection equipment, using sorbitol and bipolar Olympus devices for transurethral resection of the prostate in saline (TURPis). Haemostasia was performed using roller balls. Anticoagulation followed a prescribed scheme by cardiologists and infectious disease specialists. Statistical analysis was conducted using IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp. RESULTS Among the 138 hospitalized patients affected by both BPH and COVID-19, 18 required emergency endoscopic procedures (specifically TURP or TURPis) to achieve hemostasis (Figures 1, 2). These individuals presented persistent hematuria despite conservative treatments. The mean duration of surgery was 57.9 minutes. Patients who underwent surgery had a longer average hospital stay compared to those who did not, with durations of 10.5 days versus 7.5 days, respectively. Additionally, urethrovesical catheter insertion was necessary in 29 cases due to acute urinary retention or worsening voiding symptoms during hospitalization. These patients are scheduled for further urological evaluation following the resolution of the COVID-19 episode. In a cohort of 53 patients for whom data were accessible, comparisons were made between the pre-COVID status and the levels of the International Prostate Symptom Score (IPSS), post-voiding residue (PVR), and quality of life (QoL). The findings revealed a mean pre-COVID IPSS value of 11.6 and a COVID-related value of 14.2, with a statistically significant difference noted (p < 0.05). The mean pre-COVID PVR was 42.3 cm2, whereas during the COVID-19 period, it measured 62.5 cm2, also exhibiting a significant difference (p < 0.05). Additionally, the QoL showed a mean pre-COVID-19 score of 2.4 and a COVID-19-associated score of 2.9, again demonstrating statistical significance (p < 0.05). CONCLUSION The onset of the SARS-CoV-2 pandemic posed novel challenges in the medical realm, impacting the approach to BPH management. A common practice was delaying treatment for chronic BPH until viral infection remission to reduce associated risks. Additionally, our study revealed a worse evolution in LUTS among individuals with severe COVID-19 symptoms.

Abstract
PURPOSE To explore the association between chronic prostatitis (CP) and the subsequent development of benign prostatic hyperplasia (BPH). METHODS Data analyzed were medical claims of Taiwan's National Health Insurance program. From 2010 to 2017, 3571 patients ≧20 years with CP diagnosed by certified urologists were enrolled. Patients with past BPH diagnosis and diagnosis of prostate cancer, inguinal hernia, interstitial cystitis, and urethritis in the past and within one year after the first CP diagnosis were excluded. Age-matched controls were randomly selected from all non-CP individuals of the same exclusion criteria in the study period with a CP/non-CP ratio of 1:4. The follow-up was made from the first CP diagnosis to death or the end of 2018. The endpoint was the newly diagnosed BPH. Cox proportional hazard regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of BPH in association with CP. RESULTS Over a maximum of 8 years of follow-up, 287 (8.03%) and 258 (0.43%) BPH events were noted for the CP and non-CP group, respectively, representing a covariate adjusted HR (aHR) of 4.30 (95% CI, 3.61-5.13). Younger patients tended to suffer from higher aHRs, especially those aged 20-39 years (aHR: 11.45, 95% CI, 5.12-25.64). CONCLUSION The Taiwan national health database indicated that CP patients had a significantly higher risk of developing BPH later than non-CP patients. Interestingly, the younger the CP is diagnosed (under 40), the greater the risk.

Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) is prevalent among elderly men, necessitating focused attention. The Prostatic Urethral Lift (PUL) procedure, a minimally invasive intervention, has emerged as a promising option for BPH management. It has shown remarkable results in ameliorating lower urinary tract symptoms (LUTS), enhancing quality of life, and preserving sexual function. This study aims to evaluate the effectiveness and safety of PUL in BPH patients. METHODS Key databases (MEDLINE, Cochrane CENTRAL, ScienceDirect, EBSCO, Google Scholar) were systematically searched using pertinent terms related to PUL and BPH. Following the PRISMA checklist, we considered only randomized controlled trials (RCTs) from 2013 to 2023. The assessment focused on LUTS, quality of life, sexual function, and adverse events within three months. Follow-up post-treatment mean values compared with controls (Sham) and the improvement from baseline to post-treatment follow-up duration were considered. Statistical analysis and risk of bias evaluation were conducted using Review Manager 5.4.1, presenting results as difference of mean values (MD) and risk ratios (RR). RESULTS A meta-analysis with a Random Effects Model of 7 RCTs involving 378 confirmed BPH patients demonstrated significant improvements in the PUL arm including International Prostate Symptom Score (IPSS) (MD 5.51, p<0.0001), maximum urinary flow rate (Qmax) (MD 2.13, p=0.0001), BPH Impact Index (BPHII) (MD 2.14, p=0.0001), and IPSS-QoL (MD 1.50, p<0.0001), without significant increase of adverse events (RR 1.51; p=0.50). Positive outcomes were observed in sexual function variables and post-void residual measurements when post-treatment values were compared to baseline. CONCLUSIONS PUL holds advantages over control interventions, providing encouraging prospects for BPH management. This study underscores the need for further exploration of PUL's efficacy and safety in BPH patients.

Abstract
Benign prostatic hyperplasia (BPH) as the leading cause of urination disorder is still a refractory disease, and there have no satisfied drugs or treatment protocols yet. With identifying excessive Zn2+ , inflammation, and oxidative stress as the etiology of aberrant hyperplasia, an injectable sodium alginate (SA) and glycyrrhizic acid (GA)-interconnected hydrogels (SAGA) featuring Zn2+ -triggered in situ gelation are developed to load lonidamine for reprogramming prostate microenvironment and treating BPH. Herein, SAGA hydrogels can crosslink with Zn2+ in BPH via coordination chelation and switch free Zn2+ to bound ones, consequently alleviating Zn2+ -arisen inflammation and glycolysis. Beyond capturing Zn2+ , GA with intrinsic immunoregulatory property can also alleviate local inflammation and scavenge reactive oxygen species (ROS). Intriguingly, Zn2+ chelation-bridged interconnection in SAGA enhances its mechanical property and regulates the degradation rate to enable continuous lonidamine release, favoring hyperplastic acini apoptosis and further inhibiting glycolysis. These multiple actions cooperatively reprogram BPH microenvironment to alleviate characteristic symptoms of BPH and shrink prostate. RNA sequencing reveals that chemotaxis, glycolysis, and tumor necrosis factor (TNF) inflammation-related pathways associated with M1-like phenotype polarization are discerned as the action rationales of such endogenous Zn2+ -triggered in situ hydrogels, providing a candidate avenue to treat BPH.

Abstract
Bladder outlet obstruction (BOO) is the primary clinical manifestation of benign prostatic hyperplasia, the most common urinary system disease in elderly men, and leads to associated lower urinary tract symptoms. Although BOO is reportedly associated with increased systemic oxidative stress (OS), the underlying mechanism remains unclear. The elucidation of this mechanism is the primary aim of this study. A Sprague-Dawley rat model of BOO was constructed and used for urodynamic monitoring. The bladder tissue of rats was collected and subjected to real-time reverse transcription-quantitative polymerase chain reaction (RT-qPCR), histological examination, and immunohistochemical staining. Through bioinformatics prediction, we found that transforming growth factor β2 (TGFβ2) expression was upregulated in rats with BOO compared with normal bladder tissue. In vitro analyses using primary bladder smooth muscle cells (BSMCs) revealed that hydrogen peroxide (H2O2) induced TGFβ2 expression. Moreover, H2O2 induced epithelial-to-mesenchymal transition (EMT) by reducing E-cadherin, an endothelial marker and CK-18, a cytokeratin maker, and increasing mesenchymal markers, including N-cadherin, vimentin, and α-smooth muscle actin (α-SMA) levels. The downregulation of TGFβ2 expression in BSMCs using siRNA technology alleviated H2O2-induced changes in EMT marker expression. The findings of the study indicate that TGFβ2 plays a crucial role in BOO by participating in OS-induced EMT in BSMCs.

Effects of L-Carnitine and Coenzyme Q10 Supplementation on Lower Urinary Tract Symptoms in Men with Benign Prostatic Hyperplasia: A Randomized, Controlled, Clinical Trial. Nutr Cancer 2024; 76:207-214. [PMID: 38105612 DOI: 10.1080/01635581.2023.2295578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 12/11/2023] [Indexed: 12/19/2023]
Abstract
The prevalence of benign prostatic hyperplasia (BPH) and its associated lower urinary tract symptoms (LUTS) increases with age. Considering that BPH drug treatment is associated with complications, this study aimed to investigate the effects of L-carnitine (LC) and Coenzyme Q10 (CoQ10) supplementation as an adjunct therapy to finasteride in the management of LUTS in older men affected with BPH. Fifty eligible volunteers (25 per group) were randomly assigned to either intervention (finasteride + LC and CoQ10 supplements) or control (finasteride + placebo) groups. International prostate symptom score (IPSS), international index of erectile function (IIEF), quality of life index (QoL), as well as serum levels of Prostate-specific antigen (PSA), were assessed. Prostate ultrasound evaluation was also performed, before and after 8 wk of intervention. Supplementation with LC and CoQ10 led to a significant decrease in prostate volume (p < 0.001) as well as a significant increase in IIEF (p < 0.001), compared to the control group. However, there were no significant between-group differences in IPSS (p = 0.503), QoL scores (p = 0.339), and PSA levels (p = 0.482). CoQ10 and LC supplements might be beneficial in combination with standard therapies in the management of BPH and its related complications.

Increased Risk of Benign Prostate Hyperplasia (BPH) in Patients with Gout: A Longitudinal Follow-Up Study Using a National Health Screening Cohort. Diagnostics (Basel) 2023; 14:55. [PMID: 38201364 PMCID: PMC10871099 DOI: 10.3390/diagnostics14010055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 12/21/2023] [Accepted: 12/22/2023] [Indexed: 01/12/2024] Open
Abstract
A previous study reported a high risk of benign prostatic hyperplasia (BPH) in patients with gout. This study intended to evaluate the risk of BPH in gout patients. A total of 514,866 Korean National Health Insurance Service-Health Screening Cohorts were retrieved from 2002 to 2019. Among these individuals, 14,961 gout patients and 58,764 control participants were matched based on demographic factors. The incidence of BPH during the follow-up periods was collected for both the gout and control groups. The risk of BPH was analyzed using stratified Cox proportional hazard models, and hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated. Secondary analyses were conducted based on demographic factors and comorbidities. The incidence of BPH was 23.40% in gout patients and 20.70% in control participants. In the adjusted model, the HR of BPH was 1.13-fold higher in gout patients than in the control group (95% CI = 1.09-1.18). Compared with the ≥60-year-old group, the <60-year-old group demonstrated a higher HR for BPH in gout patients (1.19 [1.13-1.24] vs. 1.07 [1.01-1.13]). The risk of BPH in gout patients was consistent according to various comorbidities. Patients with gout demonstrated a greater risk of BPH than participants without gout. The young adult population had a higher risk of BPH related to gout.

Bello II, Omigbodun A, Morhason-Bello I. Common salt aggravated pathology of testosterone-induced benign prostatic hyperplasia in adult male Wistar rat. BMC Urol 2023; 23:207. [PMID: 38082261 PMCID: PMC10712029 DOI: 10.1186/s12894-023-01371-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 11/20/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) is a major health concern associated with lower urinary tract symptoms and sexual dysfunction in men. Recurrent inflammation, decreased apoptotic rate and oxidative stress are some of the theories that explain the pathophysiology of BPH. Common salt, a food additive, is known to cause systemic inflammation and redox imbalance, and may serve as a potential risk factor for BPH development or progression. This study examined the effect of common salt intake on the pathology of testosterone-induced BPH. METHODS Forty male Wistar rats were randomly divided into four equal groups of 10: a control and three salt diet groups-low-salt diet (LSD), standard-salt diet (SSD) and high-salt diet (HSD). The rats were castrated, allowed to recuperate and placed on salt-free diet (control), 0.25% salt diet (LSD), 0.5% salt diet (SSD) and 1.25% salt diet (HSD) for 60 days ad libitum. On day 33, BPH was induced in all the rats with daily injections of testosterone propionate-Testost® (3 mg/kg body weight) for 28 days. The rats had overnight fast (12 h) on day 60 and were euthanized the following day in order to collect blood and prostate samples for biochemical, molecular and immunohistochemistry (IHC) analyses. Mean ± SD values were calculated for each group and compared for significant difference with ANOVA followed by post hoc test (Tukey HSD) at p < 0.05. RESULTS This study recorded a substantially higher level of IL-6, IL-8 and COX-2 in salt diet groups and moderate IHC staining of COX-2 in HSD group. The prostatic level of IL-17, IL-1β, PGE2, relative prostate weight and serum PSA levels were not statistically different. The concentrations of IGF-1, TGF-β were similar in all the groups but there were multiple fold increase in Bcl-2 expression in salt diet groups-LSD (13.2), SSD (9.5) and HSD (7.9) and multiple fold decrease in VEGF expression in LSD (-6.3), SSD (-5.1) and HSD (-14.1) compared to control. Activity of superoxide dismutase (SOD) and concentration of nitric oxide rose in LSD and SSD groups, and SSD and HSD groups respectively. Activities of glutathione peroxidase and catalase, and concentration of NADPH and hydrogen peroxide were not significantly different. IHC showed positive immunostaining for iNOS expression in all the groups while histopathology revealed moderate to severe prostatic hyperplasia in salt diet groups. CONCLUSIONS These findings suggest that low, standard and high salt diets aggravated the pathology of testosterone-induced BPH in Wistar rats by promoting inflammation, oxidative stress, while suppressing apoptosis and angiogenesis.

Features of patients referring to the outpatient office due to benign prostatic hyperplasia: analysis of a national prospective cohort of 5815 cases. Prostate Cancer Prostatic Dis 2023; 26:730-735. [PMID: 35869394 DOI: 10.1038/s41391-022-00575-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 06/10/2022] [Accepted: 07/02/2022] [Indexed: 11/08/2022]
Abstract
BACKGROUND Evidence on clinical presentation of benign prostatic hyperplasia (BPH) is scarce, and studies involving outpatients are lacking. We aimed to provide an insight into the contemporary Italian scenario of BPH-affected outpatients using symptom scores (International Prostate Symptom Score [IPSS], BPH Impact Index [BII]), and to compare characteristics of patients with known BPH and those first-diagnosed at the visit. METHODS "IMPROVING THE PATH" project working group designed a questionary prospectively administered to BPH-affected outpatients by urologists. A cross-sectional study was performed. Data were adjusted for patient age as a potential confounding factor. RESULTS Of 5815 patients enrolled, BPH was already diagnosed in 4144 (71.3%), and not in 1671 (28.7%). Patients with known BPH, compared to newly diagnosed, were older (median 68 versus [vs] 55), had more frequent smoking (smoker 27.2 vs 22.6%, and ex-smoker 16.4 vs 12.5%) and drinking habits (55.4 vs 45.1%), were more frequently affected by hypertension (60.0 vs 42.4%), obesity (15.3 vs 9.6%), diabetes (17.9 vs 12.5%), and cardiovascular diseases (14.2 vs 9.5%), p < 0.001. At IPSS, moderate and severe symptoms correlated with already known BPH (56.1 vs 47.3% and 24.8 vs 7.8%), whereas newly diagnosed patients showed milder symptoms (44.9 vs 19.1%), all p < 0.001. At BII, concern for one's health and time lost due to urinary problems were higher in patients with known BPH (p < 0.001). For these patients, the urologist changes at least one of the ongoing medications in 63.5%. For patients newly diagnosed, supplements/phytotherapeutics, alpha-blockers, and 5-alfa reductase inhibitors were prescribed in 54.6%, 21.6%, and 7.1%, respectively. CONCLUSIONS Despite medical treatment, natural history of BPH leads to a progressive deterioration of symptoms. This may reflect the difference between newly diagnosed patients and those with known BPH in lifestyle and associated comorbidities. A healthy lifestyle and treatments including local anti-inflammatory agents may delay worsening of symptoms and improve quality of life.

Abstract
BACKGROUND There have been few investigations on the association between depression and benign prostatic hyperplasia (BPH). This study aims to explore the correlation between depression and BPH among middle-aged and older men in India. METHODS We utilized data from male individuals aged 45 years and older who participated in the initial wave (2017-2018) of the Longitudinal Aging Study in India (LASI). The presence of BPH symptoms was based on self-reported information, while depressive symptoms were evaluated using CESD-10. The analysis was a cross-sectional study conducted on a final sample size of 30,108 male participants. To examine associations, we employed multivariate logistic regression analysis along with subgroup analysis and interaction tests. RESULTS A total of 439 (1.46%) men reported BPH and had a higher depression score (10.18 ± 4.22 vs. 9.28 ± 4.00). The findings indicated a significant association between the depression score and the likelihood of developing BPH, even after accounting for all potential confounding variables (OR = 1.054, 95% CI: 1.030-1.078, p < 0.00001). The participants were then categorized into a depression group and a normal group based on their CESD-10 score, using a threshold of 10 to ascertain the existence or nonexistence of depression. After adjusting for all variables in model IV, the findings continued to exhibit statistical significance (OR = 1.611, CI: 1.327-1.955, p < 0.00001). Significant interaction effects of age, education level, caste or tribe, and alcohol consumption were observed (p for interaction < 0.05). CONCLUSION Our research found that BPH was significantly linked to the presence of depressive symptoms among middle-aged and elderly Indian men. Additional prospective research is necessary to clarify this association and investigate potential mechanisms.

Abstract
We report a case of an exophytic benign prostatic hyperplasia presenting as a polycystic pelvic mass. A 69-year-old man presented with an incidental finding of a pelvic mass of over 18 years. Digital rectal examination revealed a mass on the right anterior rectal wall 8 cm from the anal opening. His current prostate-specific antigen was 3.187 ng/mL. Enhanced computed tomography and magnetic resonance imaging demonstrated an occupancy in the right pelvis. A laparoscopic resection of the pelvic tumor was performed and pathologists identified it as an exophytic benign prostatic hyperplasia nodule. No significant recurrence was found at the 6-month follow-up.

Probenecid ameliorates testosterone-induced benign prostatic hyperplasia: Implications of PGE-2 on ADAM-17/EGFR/ERK1/2 signaling cascade. J Biochem Mol Toxicol 2023; 37:e23450.

Abstract
Benign prostatic hyperplasia (BPH) is one of the most prevalent clinical disorders in the elderly. Probenecid (Prob) is a well-known FDA-approved therapy for gout owing to its uricosuric effect. The present study evaluated the use of Prob for BPH as a COX-2 inhibitor. Prob (100 and 200 mg/kg) was intraperitoneally injected into male Wistar rats daily for 3 weeks. In the second week, testosterone (3 mg/kg) was subcutaneously injected to induce BPH. Compared with BPH-induced rats, Prob treatment reduced prostate weight and index and improved histopathological architecture. The protease activity of ADAM-17/TACE and its ligands (TGF-α and TNF-α) were regulated by prob, which in turn abolished EGFR phosphorylation, and several inflammatory mediators (COX-2, PGE2, NF-κB (p65), and IL-6) were suppressed. By reducing the nuclear import of extracellular regulated kinase protein 1/2 (ERK1/2), Prob helped re-establish the usual equilibrium between antiapoptotic proteins like Bcl-2 and cyclin D1 and proapoptotic proteins like Bax. All of these data point to Prob as a promising treatment for BPH because of its ability to inhibit COX-2-syntheiszed PGE2 and control the ADAM-17/TGF-α-induced EGFR/ERK1/2 signaling cascade. These findings might help to repurpose Prob for the treatment of BPH.

Abstract
One of the most common urological diseases is benign prostatic hyperplasia (BPH), with a high prevalence in the middle-aged and elderly male population. Patient's mental and physical health is affected significantly by this condition, causing them considerable discomfort. During the development of BPH, a synergistic effect occurs in response to inflammation, oxidative stress, and apoptosis induced by the activation of macrophages. The nuclear factor erythroid2-related factor 2 (Nrf2) signaling pathway can mediate macrophage activation and inhibit prostate hyperplasia by suppressing pro-inflammatory factors, anti-oxidative stress disorder, and initiating apoptosis. The purpose of this study was to review the mechanism of action of Nrf2 signaling pathway-mediated macrophage activation on the immune microenvironment of BPH and to summarize the Chinese medicine based on Nrf2 to provide an overview of BPH treatment options.

PURPOSE This study aimed to assess the impact of perioperative care based on the Roy Adaptation Model (RAM) on psychological well-being, postoperative pain, and health-related quality of life (HRQoL) in elderly patients with benign prostatic hyperplasia (BPH) undergoing transurethral resection of the prostate (TURP). METHODS A total of 160 elderly patients diagnosed with BPH between June 2021 and June 2022 and scheduled for TURP were randomly assigned to either the routine care group (n = 80) or the RAM group (n = 80). The RAM group received standard care supplemented with interventions based on the RAM model. Negative emotions measured by the Hospital Anxiety and Depression Scale (HADS), pain intensity by the Visual Analog Scale (VAS), and HRQoL by the 36-Item Short Form Health Survey (SF-36) were measured at the preoperative visit (T0), at 30 days (T1), and at 3 months of (T2) follow‑up. RESULTS Repeated measures ANOVA revealed significant differences in psychological well-being, postoperative pain intensity, and HRQoL within both the routine care and RAM groups across the three time points. Holm-Sidak's multiple comparisons test confirmed significant differences between each time point for both groups. The RAM intervention led to significant reductions in anxiety and depression levels, alleviation of postoperative pain intensity, and improvements in various domains of HRQoL at T1 and T2 compared to routine care. CONCLUSION Incorporating the RAM model into perioperative care for elderly patients undergoing TURP for BPH has shown promising results in improving psychological well-being, reducing postoperative pain intensity, and enhancing HRQoL.

Mechanism of RhoA regulating benign prostatic hyperplasia: RhoA-ROCK-β-catenin signaling axis and static & dynamic dual roles. Mol Med 2023; 29:139. [PMID: 37864185 PMCID: PMC10589999 DOI: 10.1186/s10020-023-00734-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 09/22/2023] [Indexed: 10/22/2023] Open
Abstract
BACKGROUND The pathogenesis of benign prostatic hyperplasia (BPH) has not been fully elucidated. Ras homology family member A (RhoA) plays an important role in regulating cell cytoskeleton, growth and fibrosis. The role of RhoA in BPH remains unclear. METHODS This study aimed to clarify the expression, functional activity and mechanism of RhoA in BPH. Human prostate tissues, human prostate cell lines, BPH rat model were used. Cell models of RhoA knockdown and overexpression were generated. Immunofluorescence staining, quantitative real time PCR (qRT-PCR), Western blotting, cell counting kit-8 (CCK-8), flow cytometry, phalloidine staining, organ bath study, gel contraction assay, protein stability analysis, isolation and extraction of nuclear protein and cytoplasmic protein were performed. RESULTS In this study we found that RhoA was localized in prostate stroma and epithelial compartments and was up-regulated in both BPH patients and BPH rats. Functionally, RhoA knockdown induced cell apoptosis and inhibited cell proliferation, fibrosis, epithelial-mesenchymal transformation (EMT) and contraction. Consistently, overexpression of RhoA reversed all aforementioned processes. More importantly, we found that β-catenin and the downstream of Wnt/β-catenin signaling, including C-MYC, Survivin and Snail were up-regulated in BPH rats. Downregulation of RhoA significantly reduced the expression of these proteins. Rho kinase inhibitor Y-27632 also down-regulated β-catenin protein in a concentration-dependent manner. However, overexpression of β-catenin did not affect RhoA-ROCK levels, suggesting that β-catenin was the downstream of RhoA-ROCK regulation. Further data suggested that RhoA increased nuclear translocation of β-catenin and up-regulated β-catenin expression by inhibiting its proteasomal degradation, thereby activating Wnt/β-catenin signaling. Overexpression of β-catenin partially reversed the changes in cell growth, fibrosis and EMT except cell contraction caused by RhoA downregulation. Finally, Y-27632 partially reversed prostatic hyperplasia in vivo, further suggesting the potential of RhoA-ROCK signaling in BPH treatment. CONCLUSION Our novel data demonstrated that RhoA regulated both static and dynamic factors of BPH, RhoA-ROCK-β-catenin signaling axis played an important role in the development of BPH and might provide more possibilities for the formulation of subsequent clinical treatment strategies.

Development of Novel Tamsulosin Pellet-Loaded Oral Disintegrating Tablet Bioequivalent to Commercial Capsule in Beagle Dogs Using Microcrystalline Cellulose and Mannitol. Int J Mol Sci 2023; 24:15393. [PMID: 37895073 PMCID: PMC10607519 DOI: 10.3390/ijms242015393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 10/13/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
In this study, we developed a tamsulosin pellet-loaded orally disintegrating tablet (ODT) that is bioequivalent to commercially available products and has improved patient compliance using microcrystalline cellulose (MCC) and mannitol. Utilizing the fluid bed technique, the drug, sustained release (SR) layer, and enteric layer were sequentially prepared by coating MCC pellets with the drug, HPMC, Kollicoat, and a mixture of Eudragit L and Eudragit NE, respectively, resulting in the production of tamsulosin pellets. The tamsulosin pellet, composed of the MCC pellet, drug layer, SR layer, and enteric layer at a weight ratio of 20:0.8:4.95:6.41, was selected because its dissolution was equivalent to that of the commercial capsule. Tamsulosin pellet-loaded ODTs were prepared using tamsulosin pellets and various co-processed excipients. The tamsulosin pellet-loaded ODT composed of tamsulosin pellets, mannitol-MCC mixture, silicon dioxide, and magnesium stearate at a weight ratio of 32.16:161.84:4.0:2.0 gave the best protective effect on the coating process and a dissolution profile similar to that of the commercial capsule. Finally, no significant differences in beagle dogs were observed in pharmacokinetic parameters, suggesting that they were bioequivalent. In conclusion, tamsulosin pellet-loaded ODTs could be a potential alternative to commercial capsules, improving patient compliance.

Abstract
As men age, a growing number develop benign prostatic hyperplasia (BPH). According to previous research, diabetes may be a risk factor. Pyruvate dehydrogenase kinase 4 (PDK4) is closely related to glucose metabolism and plays a role in the onset and progression of numerous illnesses. This study aimed to determine the direct effects of high glucose environment on prostate epithelial cells, in particular by altering PDK4 expression levels. In this investigation, normal prostatic epithelial cells (RWPE-1) and human benign prostatic hyperplasia epithelial cells (BPH-1) were treated with 50 mM glucose to show the alteration of high glucose in prostate cells. PDK4-target siRNA, PDK4-expression plasmid were used to investigate the effects of PDK4. Rosiglitazone (RG), a PPARγ agonist, with the potential to up-regulate PDK4 expression was also used for treating prostate cells. The expression of PDK4 in human prostate samples was also analyzed. The effects of high glucose therapy on BPH-1 and RWPE-1 cells were demonstrated to enhance proliferation, epithelial-mesenchymal transition (EMT), suppress apoptosis, and down-regulate PDK4 expression. Additionally, diabetes-related BPH patients had reduced PDK4 expression. Following the application of PDK4-target siRNA, a comparable outcome was seen. The PDK4-expression plasmid therapy, however, produced the opposite results. RG with the ability to elevate PDK4 expression might be used to treat BPH. Changes in the metabolism of lipids and glucose may be the cause of these consequences. These findings showed that high glucose treatment might facilitate BPH development, and may be related to the down-regulation of PDK4. PDK4 might be a potential therapeutic target of BPH.

The causal effect of metabolic syndrome and its components on benign prostatic hyperplasia: A univariable and multivariable Mendelian randomization study. Prostate 2023; 83:1358-1364. [PMID: 37455410 DOI: 10.1002/pros.24598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 07/03/2023] [Accepted: 07/07/2023] [Indexed: 07/18/2023]
Abstract
BACKGROUND Previous observational studies have indicated that metabolic abnormalities are associated with benign prostatic hyperplasia (BPH). The limitations of the research methodology of observational studies do not allow causal inference to be drawn; however, Mendelian randomization (MR) can clarify this. METHODS Using summary-level data from genome-wide association studies, we conducted a two-sample MR study to examine the causality of the metabolic syndrome (MetS) and its components on BPH (26,358 BPH cases and 110,070 controls). The random-effects inverse-variance weighted was employed as the primary method for MR analyses. RESULTS We observed that genetically predicted waist circumference (WC) (odds ratio [OR] = 1.236, 95% confidence interval [CI]: 1.034-1.478, p = 0.020) and diastolic blood pressure (DBP) (OR = 1.011, 95% CI: 1.002-1.020, p = 0.020) were significantly positively associated with BPH risk. We did not identify a causal effect of MetS (OR = 0.975, 95% CI: 0.922-1.031, p = 0.375), systolic blood pressure (OR = 1.004, 95% CI: 0.999-1.008, p = 0.115), triglycerides (OR = 1.016, 95% CI: 0.932-1.109, p = 0.712), high-density lipoprotein (OR = 1.005, 95% CI: 0.930-1.086, p = 0.907), and fasting blood glucose (OR = 1.037, 95% CI: 0.874-1.322, p = 0.678) on BPH. In the multivariable MR analysis, we observed that the risk effect of DBP (OR = 1.013, 95% CI: 1.000-1.026, p = 0.047) on BPH persisted after conditioning with WC (OR = 1.132, 95% CI: 0.946-1.356, p = 0.177). CONCLUSIONS Our study provides genetic evidence supporting the causal effect of DBP on BPH, although the effect of WC needs to be further validated.

J Arthroplasty 2023; 38:2142-2148. [PMID: 37172791 DOI: 10.1016/j.arth.2023.04.067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 04/27/2023] [Accepted: 04/30/2023] [Indexed: 05/15/2023] Open
Abstract
BACKGROUND Whether symptomatic benign prostatic hyperplasia (sBPH), which is common among middle-aged and older men, affects the risk of periprosthetic joint infection (PJI) remains controversial. The present study explored this question among men undergoing total knee arthroplasty and total hip arthroplasty (TKA and THA). METHODS We retrospectively analyzed medical data from 948 men who underwent primary TKA or THA at our institution between 2010 and 2021. We compared the incidence of postoperative complications such as PJI, urinary tract infection (UTI), and postoperative urinary retention (POUR) between 316 patients (193 hips and 123 knees) who did and 632 patients who did not have sBPH; the 2 groups of patients were matched to each other in a 1:2 ratio based on numerous clinical demographic variables. In the subgroup analyses, we stratified sBPH patients according to whether they began anti-sBPH medical therapy prior to arthroplasty. RESULTS PJI following primary TKA was significantly more common among sBPH patients than among patients who did not have sBPH (4.1 vs 0.4%; P = .029), as were UTI (P = .029), and POUR (P < .001). Patients who had sBPH also had an increased incidence of UTI (P = .006) and POUR (P < .001) following THA. Among sBPH patients, those who started anti-sBPH medical therapy before TKA suffered significantly lower incidence of PJI than those who did not. CONCLUSION Symptomatic benign prostatic hyperplasia is a risk factor for PJI after primary TKA among men, and starting appropriate medical therapy before surgery can reduce the risk of PJI following TKA and postoperative urinary complications following TKA and THA.

Abstract
Autophagy is a highly conserved, lysosome-dependent biological mechanism involved in the degradation and recycling of cellular components. There is growing evidence that autophagy is related to male reproductive biology, particularly spermatogenic and endocrinologic processes closely associated with male sexual and reproductive health. In recent decades, problems such as decreasing sperm count, erectile dysfunction, and infertility have worsened. In addition, reproductive health is closely related to overall health and comorbidity in aging men. In this review, we will outline the role of autophagy as a new player in aging male reproductive dysfunction and prostate cancer. We first provide an overview of the mechanisms of autophagy and its role in regulating male reproductive cells. We then focus on the link between autophagy and aging-related diseases. This is followed by a discussion of therapeutic strategies targeting autophagy before we end with limitations of current studies and suggestions for future developments in the field.

Abstract
Mitoquinone (MitoQ), a mitochondria-targeted antioxidant, has been used to treat several diseases. The present study aimed to investigate the therapeutic effects of MitoQ in benign prostatic hyperplasia (BPH) models and their underlying molecular mechanisms. In this study, we determined that MitoQ inhibited dihydrotestosterone (DHT)-induced cell proliferation and mitochondrial ROS by inhibiting androgen receptor (AR) and NOD-like receptor family pyrin domain-containing 3 (NLRP3) signaling in prostate epithelial cells. Molecular modeling revealed that DHT may combine with AR and NLRP3, and that MitoQ inhibits both AR and NLRP3. AR and NLRP3 downregulation using siRNA showed the linkage among AR, NLRP3, and MitoQ. MitoQ administration alleviated pathological prostate enlargement and exerted anti-proliferative and antioxidant effects by suppressing the AR and NLRP3 signaling pathways in rats with BPH. Hence, our findings demonstrated that MitoQ is an inhibitor of NLPR3 and AR and a therapeutic agent for BPH treatment.

Mechanism of Androgen-Independent Stromal Proliferation in Benign Prostatic Hyperplasia. Int J Mol Sci 2023; 24:11634. [PMID: 37511400 PMCID: PMC10380833 DOI: 10.3390/ijms241411634] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 07/14/2023] [Accepted: 07/16/2023] [Indexed: 07/30/2023] Open
Abstract
Benign prostatic hyperplasia (BPH) is a chronic proliferative disease showing stromal-dominant proliferation. However, the detailed proliferation mechanism has remained unclear. Although aging and androgen have been reported as definitive risk factors for BPH, recent studies have focused on the involvement of androgen-independent factors. Androgen-independent factors include ischemia, oxidative stress, metabolic syndrome, infection, autoimmune reactions, and inflammation, with inflammation in BPH tissues playing a central role in the BPH proliferative process. Inflammation in BPH tissues by various factors finally leads to tissue remodeling and stromal proliferation through the wound healing process of the prostate. To elucidate the proliferative mechanism of BPH, a study using whole-genome gene expression analysis in a stromal-dominant BPH rat model was performed and showed that immune response-related pathways and complement classical pathways are activated. Furthermore, expression analysis using this BPH rat model showed that the autoimmune reaction triggered complement pathway activation in the proliferative process of BPH. BPH is a multifactorial disease, and understanding the role of androgen-independent factors including immune responses contributes to elucidating the pathogenesis of BPH. Androgen-independent factors may lead to new therapeutic targets for BPH, and further development of this research is expected.

Abstract
Studies to date have yielded conflicting results on associations between components of metabolic syndrome (MetS) and bone mineral density (BMD), particularly in men. This current systematic review and meta-analysis addresses the existing gap in the literature and aims to evaluate bone mineral density (BMD) at the femoral neck (FN) and lumbar spine (LS) in men diagnosed with MetS. The two study authors independently searched PubMed, Cinahl, Embase, and Web of Science up to 8 February 2022 for studies in English. The inclusion criteria were (i) diagnosis of MetS according to the NCEP-ATP III 2001 criteria; (ii) adult male demographic; (iii) analyzable data on BMD in at least two sites using dual-energy X-ray absorptiometry (DXA), and (iv) original observational studies. Case reports and non-English articles were excluded. We analyzed the results of seven studies providing data on bone density in men with MetS. Results: Based on random effect weights, the mean BMD of the femoral neck and lumbar spine were 0.84 and 1.02, respectively. The mean lumbar spine T-score was -0.92. In meta-regression analysis, the variances in mean BMD in the lumbar spine and femoral neck could not be significantly explained by BMI (lumbar BMD: Q = 1.10, df = 1, p = 0.29; femoral neck BMD: Q = 0.91, df = 1, p = 0.34). Our meta-analysis suggests normal bone mass in adult males with MetS. Due to the high heterogeneity in the seven analyzed studies and the lack of control groups in these studies, further research is needed to fully elucidate the associations between MetS and its components and BMD in men.

Abstract
BACKGROUND Nettle is a medicinal plant rich in bioactive molecules. The composition of nettle leaves and stems has been extensively studied, whereas the root has been insufficiently investigated. Therefore, the present study aimed to optimize the parameters of advanced extraction technique, pressurized liquid extraction (PLE), for the lipid fraction of nettle root rich in triterpenoid derivatives and to compare the efficiency of isolation under optimal conditions with conventional Soxhlet extraction (SE). RESULTS The PLE yields ranged from 0.39-1.63%, whereas the total content of triterpenoid derivatives ranged from 43.50-78.26 mg 100 g-1 , with nine sterols and three pentacyclic triterpenoids identified and quantified within a total range of 42.81-76.57 mg 100 g-1 and 0.69-1.68 mg 100 g-1 dried root, respectively. The most abundant sterol and pentacyclic triterpenoid were β-sitosterol and β-amyrin acetate, with mean values of 50.21 mg 100 g-1 and 0.56 mg 100 g-1 dried root. CONCLUSION The optimal PLE conditions were 150 °C/5 min/four cycles and showed significantly better performance compared to SE (68 °C, 8 h), establishing an excellent technique for the isolation of the nettle root lipid fraction. Also, triterpenoid derivatives from nettle could be used as functional ingredients for the development of new foods and dietary supplements. © 2022 Society of Chemical Industry.

Abstract
PURPOSE Benign prostatic hyperplasia (BPH) describes common noncancerous prostate enlargement. BPH is usually associated with lower urinary tract symptoms and an increased risk of cerebrovascular diseases, such as stroke and its recurrence. White matter hyperintensities (WMHs), markers of cerebral injury, increase the risk of stroke, cognitive impairment, dementia, and death. The relationship between BPH and WMHs remains unclear. This study aimed to determine the association between BPH and WMHs. METHODS A total of 788 male patients from the First Affiliated Hospital of Kunming Medical University from July 2019 to September 2021 were enrolled in this cross-sectional study. BPH was assessed by abdominal ultrasound, and three independent neuroradiologists rated the presence or absence of WMHs. Multiple imputations of chained equations were used to handle missing data. Logistic regression was used to assess the relationship between BPH and WMHs. RESULTS Patients with BPH presented an increased risk of WMHs with a crude odds ratio (OR) of 2.76 (95% CI, 2.02-3.79) and an adjusted OR of 1.75 (95% CI, 1.24-2.48) after controlling for potential confounding factors in the multivariate logistic regression. CONCLUSION We found that BPH was closely associated with WMHs in male Chinese individuals.

Abstract
The present study aims to analyze the impact of PRO 160/120 prescriptions on the incidence of urinary incontinence, polyuria (including nocturia), urinary retention, and erectile dysfunction in a real-world setting in Germany and to compare these data with data for the 5-ARIs finasteride and dutasteride, and the α1-adrenoceptor antagonists tamsulosin and tamsulosin/dutasteride fixed-dose combination. This retrospective study was based on the IQVIA Disease Analyzer database and included male patients with an initial prescription of PRO 160/120, finasteride, dutasteride, tamsulosin, or tamsulosin/dutasteride fixed-dose combination between January 2010 and September 2020. Multivariable logistic regression analyses adjusted for age, health insurance, specialty, and relevant co-diagnoses were performed to estimate the association between PRO 160/120 prescriptions and incidence of pre-defined outcomes. A total of 77,923 patients were included in the study, 3,035 of whom received PRO 160/120. PRO 160/120 was significantly associated with reduced incidence of urinary incontinence (OR: 1.48; 95% CI: 1.10-1.98) and urinary retention compared to tamsulosin (OR: 3.39; 95% CI: 1.75-6.57 and tamsulosin/dutasteride (OR: 2.81; 95% CI: 1.35-5.82). Furthermore, PRO 160/120 significantly reduced the incidence of erectile dysfunction compared to dutasteride (OR: 2.79; 95% CI: 1.49-5.25). At the same time, patients receiving PRO 160/120 showed the same incidence of the remaining complications as those taking the reference substances. In conclusion, we observed a significant association between PRO 160/120 prescription and reduced incidence of urinary incontinence and urinary retention compared to tamsulosin and tamsulosin/dutasteride, as well as reduced incidence of erectile dysfunction compared to dutasteride.

Abstract
OBJECTIVE Benign prostate hyperplasia (BPH) is a common cause for bladder outlet obstruction (BOO) and lower urinary tract symptoms (LUTS) in men. The pathophysiology of BPH is multifactorial and inflammation has been linked with progression of BPH and LUTS. The association between histological prostatitis found at transurethral resection of the prostate (TURP) and adverse post-operative urinary outcomes is not clearly defined. Our aim was to evaluate the association between histological prostatitis and adverse post-operative urinary outcomes following TURP procedure. METHODS Patients who had undergone TURP for BPH at a single institution between 2014 and 2018 were included. The study population was divided into three cohorts: those with no histological inflammation, those with any form of inflammation and those specifically with prostatic stromal inflammation. Functional outcomes were assessed by defining a series of measurable post-operative "LUTS events" and comparing these to time-to-event profile using a Kaplan-Meier estimator. RESULTS A total 198 patients were included (no inflammation n = 101; any inflammation n = 97, prostatic stromal inflammation n = 81). All three groups were comparable in terms of baseline characteristics. The any inflammation group had significantly more adverse post-operative outcomes after TURP compared to the no inflammation group, P = 0.0065. The stromal inflammation group had more LUTS events after surgery compared to the no inflammation groups in the first year of follow-up n = 0.011; over a 5-year follow-up period the results were not statistically significant, P = 0.244. CONCLUSION Histological prostatitis is associated with worse urinary outcomes after TURP compared to no inflammation. These results are useful in improving prognostic discussions with patients after TURP.

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

Abstract
BACKGROUND/OBJECTIVES Benign prostatic hyperplasia (BPH) characterized by an enlarged prostate gland is common in elderly men. Corni Fructus (CF) and Schisandrae Fructus (SF) are known to have various pharmacological effects, including antioxidant and anti-inflammatory activities. In this study, we evaluated the inhibitory efficacy of CF, SF, and their mixture (MIX) on the development of BPH using an in vivo model of testosterone-induced BPH. MATERIALS/METHODS Six-week-old male Sprague-Dawley rats were randomly divided into seven groups. To induce BPH, testosterone propionate (TP) was injected to rats except for those in the control group. Finasteride, saw palmetto (SP), CF, SF, and MIX were orally administered along with TP injection. At the end of treatment, histological changes in the prostate and the level of various biomarkers related to BPH were evaluated. RESULTS Our results showed that BPH induced by TP led to prostate weight and histological changes. Treatment with MIX effectively improved TP-induced BPH by reducing prostate index, lumen area, epithelial thickness, and expression of BPH biomarkers such as 5α-reductase type 2, prostate-specific antigen, androgen receptor, and proliferating cell nuclear antigen compared to treatment with CF or SF alone. Moreover, MIX further reduced levels of elevated serum testosterone, dihydrotestosterone, and prostate-specific antigen in BPH compared to the SP, a positive control. BPH was also improved more by MIX than by CF or SF alone. CONCLUSIONS Based on the results, MIX is a potential natural therapeutic candidate for BPH by regulating 5α-reductase and AR signaling pathway.

Abstract
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.

Abstract
Purpose To investigate the relationship between benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) and renal function in elderly men aged 80 years and older. Patients and Methods We selected 389 elderly men aged 80-97 years with BPH/LUTS hospitalized at The Second Division of General Geriatrics, The First Affiliated Hospital of Zhengzhou University, between July 2018 and July 2020. In the cross-sectional study, patients were divided into the treatment (233 patients) and non-treatment (156 patients) groups based on whether they received treatment for BPH/LUTS. In the prospective self-case-control study, we included 129 of the non-treatment group patients who received oral BPH/LUTS medication and completed the 6-month outpatient follow-up. We compared prostate indicators and renal function in the cross-sectional study and baseline and after-treatment data in the prospective self-case-control study. Multiple linear regression analysis was performed for risk factors affecting renal function before and after BPH/LUTS treatment. Results In the cross-sectional study, renal function was significantly better in the treatment group than in the non-treatment group. In the subgroup analysis of the prospective self-case-control study, renal function significantly improved after treatment among patients with hypertension and those with chronic kidney disease (CKD) 3a, but not in the entire cohort. Multivariable linear regression analysis showed that hypertension (β=2.06, 95% CI 0.40 to 3.71) and CKD 3a (β=17.16, 95% CI 15.53 to 18.79) were independent risk factors for creatinine differences before and after treatment, whereas hypertension (β=-2.27, 95% CI -3.65 to -0.89), CKD 3a (β=-11.93, 95% CI -13.29 to -10.58), and baseline prostate volume (β=-0.11, 95% CI -0.20 to -0.02) were independent risk factors for estimated glomerular filtration rate differences before and after treatment. Conclusion Treatment for moderate and severe BPH/LUTS can improve renal function in elderly patients with hypertension or CKD 3a.

Abstract
Cadmium (Cd) is a toxic heavy metal pollutant and serves as an important environmental endocrine-disrupting chemical. Cd exposure is believed to can enhance the risks of age-related disorders including benign prostatic hyperplasia (BPH). This study was to investigate the harms of Cd exposure on mice prostate and human nonmalignant prostate epithelial RWPE-1 cells. Mice prostate fibrosis was evaluated by visualizing the prostatic collagen deposition via Masson and Sirius red staining, and detecting the content of hydroxyproline. Additionally, the epithelial-mesenchymal transition (EMT), primary ciliogenesis and SHH signaling pathways in both mice prostate and RWPE-1 cells were evaluated. It was found that Cd exposure stimulated prostatic collagen deposition, EMT and primary ciliogenesis, as well as enhanced the circ_0027470 level and reduced the miRNA-1236-3p level. Circ_0027470 functioned as a sponge of miRNA-1236-3p, which had the inhibiting target of SHH. The whole results showed that circ_0027470 promoted Cd exposure-induced prostatic fibrosis via sponging miRNA-1236-3p and subsequently stimulating SHH signaling pathway. This study shed a light on a novel molecular mechanism involved in circRNA for Cd exposure-induced prostate deficits.

Abstract
OBJECTIVE AND DESIGN Prostatic inflammation is the driving force in benign prostatic hyperplasia (BPH). This work investigated the potential modulatory effect of COX-2 inhibition on ADAM-17/EGFR/ERK1/2 axis. MATERIALS OR SUBJECTS Adult male Wistar rats were used. TREATMENT Celecoxib (10 and 20 mg/kg; i.p.) was injected i.p. daily for three weeks. Testosterone (TST) (3 mg/kg; s.c.) was used to induce BPH. METHODS Prostatic inflammation and hyperplasia were assessed by organ weight and histopathology. Inflammatory mediators were measured using ELISA technique. Protein analysis was performed using western blotting and immunohistochemistry. Gene expression analysis was performed using qRT-PCR. Statistical analyses included one-way ANOVA and Tukey's multiple comparison test. RESULTS Testosterone-treated rats had a marked increase in COX-2, prostate weight, and index. Moreover, TST-induced COX-2 was inferred from cytoskeletal changes and was attributable to the overexpression of PGE2, NF-κB (p65), and IL-6. COX-2-derived PGE2 increased the activity of ADAM-17, TGF-α, and TNF-α. Consequently, EGFR-ERK1/2 pathway was over-activated, disrupting anti-apoptotic Bcl-2, cyclin D1, and pro-apoptotic Bax. Celecoxib reversed these effects. CONCLUSION COX-2 stimulates the ERK1/2 pathway via PGE2-ADAM-17-catalyzed shedding of TGF-α in testosterone-induced BPH. The results indicate a functional correlation between inflammation and hyperplasia in BPH.

Abstract
OBJECTIVE This study aims to evaluate the lower urinary tract symptoms (LUTS) of the patients with benign prostatic hyperplasia (BPH) who were admitted due to coronavirus disease (COVID-19) and to show the effect of COVID-19 on BPH. METHODS This prospective study included patients over the age of 45 admitted due to COVID-19 between June 2021 and December 2021 and treated with alpha-blockers for BPH. During admission, the patients were evaluated by prostate volumes, prostate-specific antigen (PSA) values, and International Prostate Symptom Scores (IPSS). Furthermore, treatment duration due to COVID-19, frequency, nocturia, and voided volumes obtained from the voiding diary was recorded. Finally, the sequent IPSS values were compared by inviting the patients to the urology polyclinic in the first month. RESULTS The mean age of 142 patients was 72.42 ± 10.21 years. The IPSS scores of the patients increased from 10.66 ± 4.46 to 12.99 ± 3.58 1 month after the diagnosis (p < 0.01). Moreover, the IPSS quality of life (QoL) scores were 2.44 ± 0.58 and 2.75 ± 0.51, respectively (p < 0.01). The mean frequency obtained from the voiding diary data increased from 5.10 ± 1.5 to 5.65 ± 1.36 (p < 0.01), mean nocturia count increased from 1.13 ± 0.05 to 1.39 ± 0.66 per day (p < 0.01), and the mean voiding volume decreased from 320.56 ± 46.76 ml to 298.84 ± 39.74 ml (p < 0.01). CONCLUSION In this study, we detected an increase in LUTS during COVID-19 treatment. Therefore, it should be noted that symptomatic or asymptomatic COVID-19 patients may refer to urology polyclinics due to aggravation of LUTS.

Abstract
Background Blood loss of postoperative after prostate surgery could be related with an increase in urinary fibrinolytic activity. Tranexamic acid (TXA) is both a potent inhibitor of plasminogen and urokinase activators and a low molecular weight substance that is excreted unchanged in the urinary tract and can be administered both orally and intravenously. This study aimed to evaluate the effectiveness TXA administration in reducing bleeding in benign prostatic hyperplasia (BPH) patients who underwent open prostatectomy. Materials and Methods This double-blind randomized clinical trial was conducted on patients with BPH who underwent open prostatectomy. The first group received TXA (1 gr IV from during surgery to 48 h after surgery, 3 times/day). Twenty-four hours after surgery, the two groups were compared in terms of bleeding rate. Hemoglobin (Hb), hematocrit (HCT), and platelet (Plt) counts were also assessed before and after the intervention. Results Intervention and control groups were comparable in terms of basic and baseline values of variables at the beginning of the study (P > 0.05). The mean bleeding volume in TXA group was significantly lower than the control group 112.11 ± 53.5 and 190.00 ± 97.5 CC; P ≤ 0.001). Mean hospitalization (3.28±0.46 vs. 4.38 ± 0.95 days P < 0.001) and surgery duration (98.11 ± 37.11 vs. 128.00 ± 39.12 h; P = 0.001) were significantly lower in TXA group compared to control intervention. Conclusion According to the findings of the current study, the administration of TXA led to reduce bleeding in BPH patients who underwent open prostatectomy. Furthermore, the mean Hb, HCT, levels were significantly affected by TXA. TXA treatment approach also can reduce the surgery and hospitalization time effectively. TXA approach is recommended as effective procedure in BPH patients who underwent open prostatectomy.

Abstract
Prevalence of lower urinary tract symptoms secondary to benign prostatic hyperplasia is correlated with age. Men seeking treatment options with a low side effect profile often turn to prostate artery embolization (PAE). PAE continues to be refined with advanced tools and optimized techniques. Nonetheless, there exist controversies in terms of best practices for the management of lower urinary track symptoms (LUTS) with PAE. These controversies are essential for medical progress. Herein we suggest best practices moving forward based on currently available data. Given extensive safety data, we recommend PAE be considered alongside medical management and as a precursor to surgery. Given demonstrated efficacy across gland sizes, PAE can be performed in a single session, ideally in a hybrid angio-CT suite, without preoperative cross-sectional imaging. PAE should be initially performed with 300- to 500-μm size particles, and instead consider exploring other particles and sizes for repeat PAE. Finally, PAE can also be considered as first-line option for recurrent disease given the efficacy and excellent safety profile. This article is not meant to purport a dogma, but rather to serve as a guide to the experienced practitioner in challenging his or her own biases when performing PAE.

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