Adherence to AUA guidelines for the work-up, medical management, surgical evaluation and treatment of BPH: Work from a quality improvement collaborative.

INTRODUCTION: Previous studies noted varied adherence to clinical practice guidelines (CPGs), but studies are yet to quantify adherence to American Urological Association BPH guidelines. We studied guideline adherence in the context of a new quality improvement collaborative (QIC). METHODS: Data were collected as part of a statewide QIC. Medical records for patients undergoing select CPT codes from January 2020 to May 2022 were retrospectively reviewed for adherence to selected BPH guidelines. RESULTS: Most men were treated with transurethral resection of the prostate. Notably, 53.3% of men completed an IPSS and 52.3% had a urinalysis. 4.7% were counseled on behavioral modifications, 15.0% on medical therapy, and 100% on procedural options. For management, 79.4% were taking alpha-blockers and 59.8% were taking a 5-ARI. For evaluation, 57% had a PVR, 63.6% had prostate size measurement, 37.4% had uroflowmetry, and 12.3% were counseled about treatment failure. Postoperatively, 51.6% completed an IPSS, 57% had a PVR, 6.50% had uroflowmetry, 50.6% stopped their alpha-blocker, and 75.0% stopped their 5-ARI. CONCLUSIONS: There was adherence to preoperative testing recommendations, but patient counseling was lacking in the initial work-up and preoperative evaluation. We will convey the data to key stakeholders, expand data collection to other institutions, and devise an improvement implementation plan.

Exploring pharmacological interventions in benign prostate hyperplasia: the role of cost-effectiveness analysis in daily practice and future directions.

INTRODUCTION: Benign Prostate Hyperplasia (BPH) significantly impacts men's health and quality of life, with its prevalence rising with age. This review critically examines the cost-effectiveness of pharmacological interventions for BPH to optimize patient outcomes and healthcare resource utilization. AREAS COVERED: This review explores the integration of cost-effectiveness analysis (CEA) into clinical practice, balancing clinical efficacy with economic efficiency in BPH management. We performed a critical literature search, including recent studies on the economic evaluation of BPH treatments, focusing on pharmacotherapies such as alpha-blockers and 5-alpha reductase inhibitors. Additionally, we discussed the concept of CEA and evaluated the role of medicinal reconciliation and the avoidance of polypharmacy in favor of optimal BPH treatment. EXPERT OPINION: Cost-effectiveness analysis is crucial for evaluating BPH treatments, with evidence suggesting a shift towards surgical interventions may offer greater long-term economic benefits. However, these models must be applied cautiously, considering clinical evidence and patient preferences to ensure equitable and patient-centric healthcare.

Comparative efficacy and safety of alpha-blockers as monotherapy for benign prostatic hyperplasia: a systematic review and network meta-analysis.

Despite the availability of various drugs for benign prostatic hyperplasia (BPH), alpha(α)-blockers are the preferred first-line treatment. However, there remains a scarcity of direct comparisons among various α-blockers. Therefore, this network meta-analysis (NMA) of randomized controlled trials (RCTs) aimed to evaluate the efficacy and safety of α-blockers in the management of BPH. A comprehensive electronic search covered PubMed, Embase, Ovid MEDLINE, and Cochrane Library until August 2023. The primary endpoints comprised international prostate symptom score (IPSS), maximum flow rate (Qmax), quality of life (QoL), and post-void residual volume (PVR), while treatment-emergent adverse events (TEAEs) were considered as secondary endpoints. This NMA synthesized evidence from 22 studies covering 3371 patients with six kinds of α-blockers with 12 dose categories. IPSS has been considerably improved by tamsulosin 0.4 mg, naftopidil 50 mg and silodosin 8 mg as compared to the placebo. Based on the p-score, tamsulosin 0.4 mg had the highest probability of ranking for IPSS, PVR, and Qmax, whereas doxazosin 8 mg had the highest probability of improving QoL. A total of 297 adverse events were reported among all the α-blockers, silodosin has reported a notable number of TEAEs. Current evidence supports α-blockers are effective in IPSS reduction and are considered safer. Larger sample size with long-term studies are needed to refine estimates of IPSS, QoL, PVR, and Qmax outcomes in α-blocker users.

Efficacy and Safety of Vibegron for Persistent Symptoms of Overactive Bladder in Men Being Pharmacologically Treated for Benign Prostatic Hyperplasia: Results From the Phase 3 Randomized Controlled COURAGE Trial.

PURPOSE: The efficacy and safety of vibegron, a ß3-adrenergic receptor agonist, was assessed among men with symptoms of overactive bladder (OAB) receiving pharmacologic treatment for benign prostatic hyperplasia (BPH) in a phase 3 randomized controlled trial. MATERIALS AND METHODS: Men ≥ 45 years with OAB symptoms and BPH, treated with α-blocker with/without 5α-reductase inhibitors, were randomized 1:1 to vibegron or placebo for 24 weeks. Coprimary end points were change from baseline at week 12 in mean daily micturitions and urgency episodes. Secondary end points were change from baseline at week 12 in mean nightly nocturia and daily urge urinary incontinence episodes, International Prostate Symptom Score‒storage score, and volume voided per micturition. Safety was evaluated via adverse events (AEs). RESULTS: Of 1105 participants randomized, 965 (87.3%) completed the trial. At week 12, vibegron was associated with significant reductions vs placebo in daily micturitions (least squares mean difference [95% CI], -0.74 [-1.02, -0.46]; P < .0001) and urgency episodes (-0.95 [-1.37, -0.54]; P < .0001). Vibegron was also associated with significant improvements vs placebo at week 12 in nocturia episodes (least squares mean difference, -0.22 [-0.36, -0.09]; P = .002), urge urinary incontinence episodes (-0.80 [-1.33, -0.27]; P = .003), International Prostate Symptom Score‒storage scores (-0.9 [-1.2, -0.6]; P < .0001), and volume voided (15.07 mL [9.13-21.02]; P < .0001). AE rates were similar in vibegron (45.0%) and placebo (39.0%) arms; AEs occurring in ≥ 2% of participants were hypertension (9.0% vs 8.3%), COVID-19 (4.0% vs 3.1%), UTI (2.5% vs 2.2%), and hematuria (2.0% vs 2.5%). CONCLUSIONS: In this trial, vibegron met all primary and secondary end points and was safe and well tolerated in men with OAB symptoms and pharmacologically treated BPH.

Do alpha blockers reduce the risk of urinary retention post-transperineal prostate biopsy? A systematic narrative review.

BACKGROUND: Transperineal Prostate Biopsy (TPB) is a commonly used technique for the diagnosis of prostate cancer due to growing concerns related to infectious complications associated with transrectal ultrasound-guided prostate biopsy (TRUSB). TPB is associated with an infective complication rate of near zero, however, acute urinary retention (AUR) remains the leading complication causing morbidity. Previously in TRUSB, there was weak evidence that alpha-blockers reduce AUR rates, and their usage has been extrapolated to clinical practice with TPB. This review aims to explore if there is an evidence base for using alpha-blockers to prevent AUR following TPB. METHODS: A systematic approach was used to search Ovid Medline and Embase using keywords related to "Transperineal" and "Retention". Articles were then screened by applying inclusion and exclusion criteria to find studies that compared alpha-blocker recipients to no alpha-blocker use in the perioperative period and the subsequent effect on AUR in TPB. RESULTS: 361 records were identified in the initial search to produce 5 studies included in the final review. No randomised controlled trials (RCTs) were identified. One observational study showed a reduction in AUR rate from 12.5% to 5.3% with a single dose of tamsulosin. A previous systematic review of complications associated with prostate biopsy concluded there may be a potential benefit to alpha-blockers given in the TPB perioperative period. Three observational studies demonstrated a harmful effect related to alpha-blocker use; however, this was well explained by their clear limitations. CONCLUSION: Based on this review and the extrapolation from TRUSB data, perioperative alpha-blockers may offer some weak benefits in preventing AUR following TPB. However, there is significant scope and need for an RCT to further develop the evidence base further given the significant gap in the literature and lack of a standard alpha blocker protocol in TPB.

Medical management of benign prostatic hyperplasia.

Medical management of benign prostatic hyperplasia (BPH) has progressed gradually in recent years and remains the starting point for most symptomatic patients seeking treatment. Beyond well-known alpha-blockers and 5-alpha reductase inhibitors, there is growing evidence for the use of phosphodiesterase-5 inhibitors and beta-3 agonists in managing the condition, which may afford additional relief of "bothersome" symptoms in some patients. This review details contemporary medical management of BPH with an emphasis on the indications for certain classes of pharmacotherapy and their relative benefits and side effects. Surgical and procedural treatment of BPH is covered in a separate review.

Medical Advancements in Benign Prostatic Hyperplasia Treatments.

PURPOSE OF REVIEW: This review aims to identify and summarize the current literature on the most recent therapeutic agents and combination strategies for the medical management of lower urinary tract symptoms resulting from benign prostatic hyperplasia. RECENT FINDINGS: The latest advancements in BPH therapy have been in combination strategies. Alpha blockers continue to be the mainstay of treatment, but research is exploring the synergistic benefits of combining them with 5-alpha reductase inhibitors (5-ARIs), phosphodiesterase-5 (PDE5) inhibitors, and beta-3 agonists. The alpha-blocker + 5-ARI combination remains ideal for enlarged, significantly reducing clinical progression risk compared to monotherapy. Alpha-blocker + PDE5 inhibitor combinations appear safe and potentially beneficial for men with concomitant erectile dysfunction; sildenafil might hold an edge over tadalafil based on limited data. Beta-3 agonists show synergistic effects with alpha blockers for residual storage symptoms, offering similar efficacy to anticholinergics but with a better side effect profile.

Use of 5-alpha reductase inhibitors and risk of gastrointestinal cancers in men with benign prostatic hyperplasia: A population-based cohort study.

Pre-clinical evidence suggests that 5-alpha reductase inhibitors (5ARi's), prescribed in the treatment of benign prostatic hyperplasia, reduce colorectal and gastro-oesophageal cancer incidence via action on the male hormonal pathway. However, few studies to date have investigated this association at the population level. Our study aimed to investigate the risk of colorectal and gastro-oesophageal cancers with the use of 5ARi's. We conducted a retrospective cohort study of new users of 5ARi's and alpha-blockers among patients with benign prostatic hyperplasia in the UK Clinical Practice Research Datalink. Patients were followed until a first ever diagnosis of colorectal or gastro-oesophageal cancer, death from any cause or end of registration with the general practice or 31st of December 2017. Cox proportional hazards models with inverse probability of treatment weights were used to calculate weighted hazard ratios (HR) and 95% confidence intervals (CIs) of incident colorectal cancer or gastro-oesophageal cancer associated with the use of 5ARi's compared to alpha-blockers. During a mean follow-up of 6.6 years, we found no association between the use of 5ARi's and colorectal (HR: 1.13, 95% CI 0.91-1.41) or gastro-oesophageal (HR 1.14, 95% CI 0.76-1.63) cancer risk compared to alpha-blockers. Sensitivity analysis showed largely consistent results when varying lag periods, using multiple imputations, and accounting for competing risk of death. Our study found no association between the use of 5ARi's and risk of colorectal or gastro-oesophageal cancer in men with benign prostatic hyperplasia.

Changes in benign prostatic hyperplasia management in Valencia: a real-world evidence analysis.

INTRODUCTION AND OBJECTIVES: A training program was developed to increase general practitioners' engagement in the optimal management of Benign Prostatic Hyperplasia (BPH). The goal of this study was to evaluate changes in BPH management after the implementation of a training program. MATERIAL AND METHODS: This observational retrospective cohort study was conducted between 2019 and 2020. Aggregated data were analyzed in three evaluation periods (2010, 2012 and 2015), addressing quality indicators for diagnosis, treatment, and treatment outcomes. RESULTS: Overall, 118 795 patients who presented any data points were included. All quality indicators (number of IPSS and PSA determinations) increased between the first period and the last. Combination (α-blocker + 5-ARI) therapy was increasingly prescribed during the study periods whereas the proportion of prescriptions for single-agent α-blocker showed no significant differences among the periods analyzed. However, the total number of patients eligible for combination therapy who actually received this treatment was low in all periods (7.5%, 17.9%, and 20.1%, in 2010, 2012, and 2015, respectively). The outcome indicators revealed a decrease in referrals to the urology unit mostly among newly diagnosed patients. Even though the proportion of patients who underwent BPH-related surgeries increased significantly from the first to the second period, the number of surgeries remained stable between the second and third periods. CONCLUSIONS: The training program had a generally positive impact on the management of BPH patients in PC, but the overall study period may be insufficient to show an effect on some outcome indicators such as the number of surgeries.

[PHYTOTHERAPY AND NATURAL AGENTS IN SYMPTOMATIC BENIGN PROSTATIC HYPERPLASIA (BPH)].

INTRODUCTION: Benign prostatic hyperplasia (BPH) is a very common condition among men over 50 years of age. Some patients require immediate surgical intervention for urinary retention. However, most men have a variety of symptoms that may require treatment. Medical therapy for BPH has been well known for many years including alpha-adrenergic receptor blockers and 5-alpha reductase inhibitors. In recent years, men also receive anti-cholinergic agents, PDE5 inhibitors and other medical interventions. However, many men pursue alternative treatments and herbal medicines for BPH. We review herbs and herbal medicines that are used worldwide for symptomatic BPH. Many of them are supported by laboratory and clinical data. Mostly, mechanism of action are not fully understood but clinical benefit does support their use. Serenoa repens in hexanic extract (Permixon) is the only medicine that is backed with clinical data in high-quality clinical trials.

Transcriptomic analysis of benign prostatic hyperplasia identifies critical pathways in prostatic overgrowth and 5-alpha reductase inhibitor resistance.

BACKGROUND: The medical therapy of prostatic symptoms (MTOPS) trial randomized men with symptoms of benign prostatic hyperplasia (BPH) and followed response of treatment with a 5α-reductase inhibitor (5ARI), an alpha-adrenergic receptor antagonist (α-blocker), the combination of 5ARI and α-blocker or no medical therapy (none). Medical therapy reduced risk of clinical progression by 66% but the reasons for nonresponse or loss of therapeutic response in some patients remains unresolved. Our previous work showed that prostatic glucocorticoid levels are increased in 5ARI-treated patients and that glucocorticoids can increased branching of prostate epithelia in vitro. To understand the transcriptomic changes associated with 5ARI treatment, we performed bulk RNA sequencing of BPH and control samples from patients who received 5ARI versus those that did not. Deconvolution analysis was performed to estimate cellular composition. Bulk RNA sequencing was also performed on control versus glucocorticoid-treated prostate epithelia in 3D culture to determine underlying transcriptomic changes associated with branching morphogenesis. METHOD: Surgical BPH (S-BPH) tissue was defined as benign prostatic tissue collected from the transition zone (TZ) of patients who failed medical therapy while control tissue termed Incidental BPH (I-BPH) was obtained from the TZ of men undergoing radical prostatectomy for low-volume/grade prostatic adenocarcinoma confined to the peripheral zone. S-BPH patients were divided into four subgroups: men on no medical therapy (none: n = 7), α-blocker alone (n = 10), 5ARI alone (n = 6) or combination therapy (α-blocker and 5ARI: n = 7). Control I-BPH tissue was from men on no medical therapy (none: n = 8) or on α-blocker (n = 6). A human prostatic cell line in 3D culture that buds and branches was used to identify genes involved in early prostatic growth. Snap-frozen prostatic tissue taken at the time of surgery and 3D organoids were used for RNA-seq analysis. Bulk RNAseq data were deconvoluted using CIBERSORTx. Differentially expressed genes (DEG) that were statistically significant among S-BPH, I-BPH, and during budding and branching of organoids were used for pathway analysis. RESULTS: Transcriptomic analysis between S-BPH (n = 30) and I-BPH (n = 14) using a twofold cutoff (p < 0.05) identified 377 DEG (termed BPH377) and a cutoff < 0.05 identified 3377 DEG (termed BPH3377). Within the S-BPH, the subgroups none and α-blocker were compared to patients on 5ARI to reveal 361 DEG (termed 5ARI361) that were significantly changed. Deconvolution analysis of bulk RNA seq data with a human prostate single cell data set demonstrated increased levels of mast cells, NK cells, interstitial fibroblasts, and prostate luminal cells in S-BPH versus I-BPH. Glucocorticoid (GC)-induced budding and branching of benign prostatic cells in 3D culture was compared to control organoids to identify early events in prostatic morphogenesis. GC induced 369 DEG (termed GC359) in 3D culture. STRING analysis divided the large datasets into 20-80 genes centered around a hub. In general, biological processes induced in BPH supported growth and differentiation such as chromatin modification and DNA repair, transcription, cytoskeleton, mitochondrial electron transport, ubiquitination, protein folding, and cholesterol synthesis. Identified signaling pathways were pooled to create a list of DEG that fell into seven hubs/clusters. The hub gene centrality was used to name the network including AP-1, interleukin (IL)-6, NOTCH1 and NOTCH3, NEO1, IL-13, and HDAC/KDM. All hubs showed connections to inflammation, chromatin structure, and development. The same approach was applied to 5ARI361 giving multiple networks, but the EGF and sonic hedgehog (SHH) hub was of particular interest as a developmental pathway. The BPH3377, 5ARI363, and GC359 lists were compared and 67 significantly changed DEG were identified. Common genes to the 3D culture included an IL-6 hub that connected to genes identified in BPH hubs that defined AP1, IL-6, NOTCH, NEO1, IL-13, and HDAC/KDM. CONCLUSIONS: Reduction analysis of BPH and 3D organoid culture uncovered networks previously identified in prostatic development as being reinitiated in BPH. Identification of these pathways provides insight into the failure of medical therapy for BPH and new therapeutic targets for BPH/LUTS.

Drug-induced orthostatic hypotension: Cluster analysis of co-prescription patterns in older people in UK primary care.

PURPOSE: Over 250 medications are reported to cause orthostatic hypotension, associated with serious adverse outcomes in older adults. Studies suggest a harmful cumulative risk of orthostatic hypotension with multiple medication use. However, there is limited evidence on the potential for harm in practice, particularly which drugs is co-prescribed and may increase risk of orthostatic hypotension. METHODS: Retrospective cohort study and cluster analysis using general practice data from IQVIA Medical Research Data (IMRD) in patients aged ≥50 contributing data between 1 January 2018 and 31 December 2018. Thirteen drug groups known to be associated with orthostatic hypotension by mechanism, were analyzed and clusters generated by sex and age-band. RESULTS: A total of 602 713 individuals aged ≥50 with 283 912 (47%) men and 318 801 (53%) women were included. The most prevalent prescriptions that might contribute to orthostatic hypotension were ACE inhibitors, calcium-channel blockers, beta-blockers, selective serotonin reuptake inhibitors and uroselective alpha-blockers. We identified distinct clusters of cardiovascular system (cardiovascular system) drugs in men and women at all ages. cardiovascular system plus psychoactive drug clusters were common in women at all ages, and in men aged ≤70. cardiovascular system plus uroselective alpha-blockers were identified in men aged ≥70. CONCLUSIONS: Distinct clusters of drugs associated with orthostatic hypotension exist in practice, which change over the life course. Our findings highlight potentially harmful drug combinations that may cause cumulative risk of orthostatic hypotension in older people. This may guide clinicians about the potential of synergistic harm and to monitor for orthostatic hypotension if using combinations of cardiovascular system drugs, cardiovascular system plus psychoactive drugs and/or alpha-blockers-particularly in patients aged ≥70 or at high-risk due to comorbidity. Future research should consider quantifying the risk of drug-induced orthostatic hypotension with such drug combinations.

Immediate effect of alpha-blockers in predicting LUTS improvement in BPH patients.

INTRODUCTION: Indications for treating Benign Prostatic Hyperplasia include reversing signs and symptoms or preventing the progression of the disease. Alpha-blockers are the most effective, least costly, and best tolerated of the drugs for relieving LUTS. The aim of the study is to investigate the immediate impact of alpha-blocker medications on lower urinary tract symptoms (LUTS). MATERIALS AND METHODOLOGY: About 100 patients were included in the study-50 patients in each of the groups A (tamsulosin) and B (silodosin). The first visit was the baseline examination before starting alpha-blockers and included history, DRE, UFM, USG KUBP with PVR, IPSS, serum PSA, serum creatinine, urine analysis, urine culture, and sensitivity. All above parameters were also at 1 week, 1 month, and 3 months following starting of alpha-blockers respectively, and compared with baseline. RESULT: As of the first, second, third, and fourth visits, the mean Qmax in group A was 10.3 ± 3.3 s, 15.08 ± 2.80 s, 15.66 ± 3.18 s, and 15.12 ± 3.24 s, respectively, while in group B it was 10.1 ± 3.1 s, 14.88 ± 2.80 s, 15.18 ± 3.18 s, and 15.08 ± 3.24 s, respectively (p < 0.001). The mean voiding time was 40.87 ± 23.91 s, 36.41 ± 20.73 s, 34.85 ± 21.37 s, and 32.07 ± 21.81 s, respectively in group A, and 41.27 ± 15.49 s, 37.23 ± 21.34 s, 38.59 ± 20.83 s, and 33.10 ±22.08. In group A, the mean PVR and IPSS scores were improved and also improved in group B. CONCLUSION: The first dose of tamsulosin and silodosin improves UFM and predicts the mid-term change in UFM as well as IPSS indices in the treatment of BPH-related LUTS.

The impact of alpha-1-adrenergic receptor antagonists on the progression of Parkinson disease.

BACKGROUND: Alpha-1-adrenergic receptor antagonists (AARAs) are used in the treatment of benign prostatic hypertrophy. Some AARAs, such as terazosin, stimulate glycolysis and increase cellular adenosine triphosphate levels through activation of phosphoglycerate kinase 1 (PGK1), which has been suggested to be of therapeutic benefit in patients with Parkinson disease (PD). OBJECTIVE: This study aimed to determine whether exposure to PGK1-activating AARAs was associated with slower PD progression. METHODS: National Veterans Affairs administrative data were used to identify patients who initiated PD-related pharmacotherapy during 2000 to 2019 and were concurrently prescribed an AARA. Using a retrospective cohort design, the count of incident PD-related outcome events within 1 year of follow-up was contrasted between patients prescribed a PGK1-activating AARA versus tamsulosin (an AARA without PKG1 stimulation), using multivariable negative binomial regression. PD-related outcome events were identified using ICD codes indicating motor symptoms, nonmotor symptoms, and other potential complications as clinical markers for the progression of PD. RESULTS: A total of 127,142 patients initiated drug therapy for PD during the observation period, of whom 24,539 concurrently received an AARA. Incident PD-related events were observed significantly less often in patients receiving a PGK1 AARA (n = 14,571) than tamsulosin (n = 9968) (incidence rate ratio [IRR] 0.80 [95% CI 0.77-0.83]). These results remained significant after adjustment for confounding factors (IRR 0.85 [95% CI 0.81-0.88]) and in sensitivity analyses. CONCLUSION: Patients prescribed a PGK1-activating AARA experienced fewer PD-related outcome events than patients prescribed tamsulosin. These results may indicate a role for terazosin and other PGK1 activators in slowing disease progression of PD; however, randomized controlled trials are needed.

A prospective, randomized, open-label, parallel trial comparing the efficacy of α-blocker or 5α-reductase inhibitor withdrawal to continued combination therapy on the maintenance of lower urinary tract symptoms in men with benign prostatic hyperplasia.

BACKGROUND: It is uncertain how long combination therapy should be continued in patients with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). We investigated the withdrawal effects of α1-adrenergic receptor blocker (AB) or 5α-reductase inhibitor (5ARI) following successful combination therapy. METHODS: This prospective, randomized, open-label, parallel trial enrolled 222 patients with BPH/LUTS who showed at least a seven-point improvement in International Prostate Symptom Score-total (IPSS-T) and a ≥ 20% reduction in prostate volume (PV) following the initiation of combination therapy. Patients were randomized in a 1:1:1 ratio into continued-combination, AB-withdrawal, and 5ARI-withdrawal groups. IPSS, overactive bladder symptom score, EuroQol-five-dimensional questionnaire (EQ-5D-5L), EuroQol-visual analog scale (EQ-VAS), prostate volume (PV), maximal flow rate, postvoid residual urine (PVR), and prostate-specific antigen level were assessed every 6 months for 24 months. The predictors of IPSS-T deterioration were evaluated. RESULTS: At Month 24, IPSS-T deterioration (≥2 point) was observed in 20/72 (27.8%) and 19/72 (26.4%) patients in the AB- and 5ARI-withdrawal groups, respectively. Among them, 4/72 (5.6%) and 4/70 (5.7%) patients required readdition of the withdrawn drug (p = 0.868). In the continued combination group, EQ-VAS improved at Month 24 compared to baseline (p = 0.028). At Month 24, the AB-withdrawal group showed improvements in EQ-5D-5L, EQ-VAS, and PVR (all p < 0.005), while the 5ARI-withdrawal group showed improvement in IPSS-S (p = 0.011). Diabetes mellitus was associated with IPSS-T deterioration at Month 24 (p = 0.020). CONCLUSIONS: In patients with BPH/LUTS who are reluctant to continue combination therapy, AB or 5ARI withdrawal may be offered in men with improvement in IPSS-T by at least seven points and reduction in PV by at least 20%.

Clinical Effects of Oral Supplementation of Gamma-Cyclodextrin Curcumin Complex in Male Patients with Moderate-To-Severe Benign Prostatic Hyperplasia-Related Lower Urinary Tract Symptoms.

INTRODUCTION: Benign prostatic hyperplasia (BPH) is the most common cause of lower urinary tract symptoms (LUTSs) in males. Curcumin exhibits anti-inflammatory and anti-tumor properties which may be effective for BPH. This multi-arm observational study evaluated the real-world efficacy of QURMIN® (Gamma-cyclodextrin-curcumin Complex-CAVACURMIN®) as single or combination therapy for BPH. METHODS: Men with moderate-severe LUTS/BPH, receiving a 6-month supplementation with QURMIN® alone or in combination with BPH-specific medication were propensity score matched with patients not taking curcumin and then divided into subgroups based on concomitant baseline treatment. Cohorts were compared in the 6-month variation of IPSS, quality of life (IPSS-QoL), Benign Prostatic Hyperplasia Impact Index (BII) and uroflowmetry parameters. Curcumin tolerability was evaluated in terms of discontinuations and adverse effects. RESULTS: The 1:1 propensity score matching resulted in a treatment-naïve (n = 152), an alpha-blocker only (AB) (n = 138) and AB + 5-alpha reductase inhibitors (5-ARIs) (n = 78) subgroup. After 6 months, drug-naïve patients taking curcumin reported significant improvement in IPSS-storage (-3.9, p < 0.001), IPSS-voiding (-2.0, p = 0.011), IPSS-total (-5.9, p < 0.001), IPSS-QoL (-3.9, p < 0.001), BII (-2.0, p < 0.001), Qmax (+3.1 mL/s, p < 0.001), Qmean (+1.9 mL/s, p = 0.005), post-void residual volume (-7.7 mL, p < 0.001), and PSA (-0.3 ng/mL, p = 0.003), compared to controls. Patients taking ABs and curcumin showed improvement in IPSS-storage (-2.7, p < 0.001), IPSS-voiding (-1.3, p = 0.033), IPSS-total (-3.5, p < 0.001), IPSS-QoL (-1.1, p = 0.004), BII (-1.7, p = 0.006), Qmax (+1.0 mL/s, p = 0.006), and PSA (-0.2 ng/mL, p = 0.01). Patients taking curcumin and AB + 5-ARI showed improvement in IPSS-storage (-1.3, p = 0.007), IPSS-total (-1.6, p = 0.034), IPSS-QoL (-1.1, p < 0.001), and BII (-2.0, p < 0.001). No adverse reactions were reported for curcumin supplementation. CONCLUSION: QURMIN® (CAVACURMIN®) led to significant improvements in symptom burden, uroflow parameters, and QoL, without significant additional side effects, thus proving to be a potential new treatment for BPH, either as a single therapy or in addition to standard treatment.

Effect of Terazosin Hydrochloride Combined with Interventional Embolisation on Prostate Volume and Quality of Life of Elderly Patients with Prostatic Hyperplasia.

OBJECTIVE: This study aimed to explore the effect of terazosin hydrochloride combined with interventional embolisation on prostate volume and quality of life (QOL) of elderly patients with prostatic hyperplasia (PH). METHODS: The clinical data of 175 elderly patients with PH admitted to Central Hospital Affiliated to Shandong First Medical University from July 2020 to July 2022 were selected for retrospective analysis. Based on different treatment regimens, 89 patients who received interventional embolisation alone were included in the control group (CG), and 86 patients undergoing interventional embolisation combined with terazosin hydrochloride were included in the study group (SG). The prostate volume, serum indicators, adverse reactions and QOL of the two groups before and after treatment were compared between the two groups. RESULTS: Before treatment, no significant difference in 36-item short-form health survey (SF-36) scores, serum tumour necrosis factor-α (TNF-α) and prostate-specific antigen (PSA) was observed in both groups (p > 0.05). After treatment, the SF-36 score in the SG was 78.20 ± 6.84 points, which was significantly higher than that in the CG (72.67 ± 5.94 points). In addition, the SG had remarkably lower residual urine volume and prostate volume, higher maximum flow rate and lower TNF-α and PSA levels compared with the CG (p < 0.05). The adverse reaction rate of the SG was only 4.65%, which was significantly lower than that of the CG (14.61%, p < 0.05). CONCLUSIONS: Terazosin hydrochloride combined with interventional embolisation overtly reduces the prostate volume and improves the clinical symptoms of patients with fewer side effects, which has a certain clinical application value.

Cardiovascular Outcomes of α-Blockers vs 5-α Reductase Inhibitors for Benign Prostatic Hyperplasia.

Importance: The most prescribed class of medications for benign prostatic hyperplasia (BPH) is α-blockers (ABs). However, the cardiovascular safety profile of these medications among patients with BPH is not well understood. Objective: To compare the safety of ABs vs 5-α reductase inhibitors (5-ARIs) for risk of adverse cardiovascular outcomes. Design, Setting, and Participants: This active comparator, new-user cohort study was conducted using insurance claims data from a 20% random sample of Medicare beneficiaries from 2007 to 2019 to evaluate the 1-year risk of adverse cardiovascular outcomes. Males aged 66 to 90 years were indexed into the cohort at new use of an AB or 5-ARI. Twelve months of continuous enrollment and at least 1 diagnosis code for BPH within 12 months prior to initiation were required. Data were analyzed from January 2007 through December 2019. Exposures: Exposure was defined by a qualifying prescription fill for an AB or 5-ARI after at least 12 months without a prescription for these drug classes. Main Outcomes and Measures: Follow-up began at a qualified refill for the study drug. Primary study outcomes were hospitalization for heart failure (HF), composite major adverse cardiovascular events (MACE; hospitalization for stroke, myocardial infarction, or death), composite MACE or hospitalization for HF, and death. Inverse probability of treatment and censoring-weighted 1-year risks, risk ratios (RRs), and risk differences (RDs) were estimated for each outcome. Results: Among 189 868 older adult males, there were 163 829 patients initiating ABs (mean [SD] age, 74.6 [6.2] years; 579 American Indian or Alaska Native [0.4%], 5890 Asian or Pacific Islander [3.6%], 9179 Black [5.6%], 10 610 Hispanic [6.5%], and 133 510 non-Hispanic White [81.5%]) and 26 039 patients initiating 5-ARIs (mean [SD] age, 75.3 [6.4] years; 76 American Indian or Alaska Native [0.3%], 827 Asian or Pacific Islander [3.2%], 1339 Black [5.1%], 1656 Hispanic [6.4%], and 21 605 non-Hispanic White [83.0%]). ABs compared with 5-ARIs were associated with an increased 1-year risk of MACE (8.95% [95% CI, 8.81%-9.09%] vs 8.32% [95% CI, 7.92%-8.72%]; RR = 1.08 [95% CI, 1.02-1.13]; RD per 1000 individuals = 6.26 [95% CI, 2.15-10.37]), composite MACE and HF (RR = 1.07; [95% CI, 1.03-1.12]; RD per 1000 individuals = 7.40 [95% CI, 2.88-11.93 ]), and death (RR = 1.07; [95% CI, 1.01-1.14]; RD per 1000 individuals = 3.85 [95% CI, 0.40-7.29]). There was no difference in risk for HF hospitalization alone. Conclusions and Relevance: These results suggest that ABs may be associated with an increased risk of adverse cardiovascular outcomes compared with 5-ARIs. If replicated with more detailed confounder data, these results may have important public health implications given these medications' widespread use.

Comparison of add-on medications for persistent storage symptoms after α-blocker treatment in BPH patients - a network meta-analysis.

BACKGROUND: Patients with benign prostatic hyperplasia (BPH) receive α-blockers as first-line therapy to treat lower urinary tract symptoms; however, some individuals still experience residual storage symptoms. Antimuscarinics, ß3-agonists, and desmopressin are effective add-on medications. Nevertheless, there is currently no evidence for the appropriate choice of the first add-on medication. This systematic review aimed to investigate the clinical benefits of antimuscarinics, ß3-agonists, and desmopressin, in addition to α-blockers, for persistent storage symptoms in BPH patients. METHODS: A comprehensive literature search of randomized controlled trials (RCTs) comparing the efficacy of different add-on medications in BPH patients with persistent storage symptoms despite α-blocker treatment was conducted. Clinical outcomes included the International Prostate Symptom Score (IPSS), IPSS storage subscore, nocturia, micturition, and urgency. A network meta-analysis was performed to estimate the effect size. Surface under cumulative ranking curves (SUCRAs) were used to rank the included treatments for each outcome. RESULTS: A total of 15 RCTs were identified. Add-on imidafenacin and mirabegron resulted in significant improvement in all outcomes assessed. Other add-on medications such as desmopressin, tolterodine, solifenacin, fesoterodine, and propiverine showed positive benefits for most, but not all, outcomes. Based on the SUCRA rankings, add-on desmopressin was the best-ranked treatment for IPSS and nocturia, and add-on imidafenacin was the best for the IPSS storage subscore and micturition. CONCLUSIONS: BPH patients presenting with persistent storage symptoms despite α-blocker administration are recommended to include additional treatment. Desmopressin and imidafenacin may be considered high-priority add-on treatments because of their superior efficacy compared with other medications.

[Conservative and pharmacological treatment of benign prostatic hyperplasia : The German S2e-guideline 2023-part2]. / Konservative und medikamentöse Therapie des benignen Prostatasyndroms : Die deutsche S2e-Leitlinie 2023 ­ Teil 2.

BACKGROUND: Lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH, in German guidelines: benign prostatic syndrome [BPS]) is considered the most common disease of the lower urinary tract in men and can have a tremendous impact on the quality-of-life of affected patients. Conservative and pharmacological therapy of this disease are of great importance, both in improving LUTS and reducing progression-related complications. OBJECTIVES: Presentation of the conservative and pharmacological treatment options according to the current German S2e guideline on BPS. MATERIALS AND METHODS: Summary and overview of chapters 9 and 10 of the current German S2e guideline on BPS. RESULTS: In addition to a controlled watchful waiting for BPS patients without an absolute indication for prostate surgery, a variety of phytopharmacological formulations and synthetic drugs according to the symptomatology and clinical progress are available. Phytotherapy should, due to inconsistent study data, only be considered for mild to moderate symptoms. Synthetic drugs include alpha-blockers, 5α-reductase inhibitors, phosphodiesterase inhibitors, antimuscarinics and, more recently, the ß3-agonist mirabegron in the current guideline. In addition, various combination therapies are listed and evaluated according to their indications, effects and side effects. CONCLUSIONS: The current German S2e guideline on the diagnosis and treatment of BPS provides an evidence-based foundation for finding the best possible and most effective medication.
