THE FRENCH JOURNAL OF UROLOGY 2024; 34:102643. [PMID: 38759841 DOI: 10.1016/j.fjurol.2024.102643] [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: 02/21/2024] [Revised: 04/30/2024] [Accepted: 05/05/2024] [Indexed: 05/19/2024]
Abstract
AIM This study aimed to investigate the clinical significance of neutrophil-to-lymphocyte ratio and ultrasonic parameters in diagnosing bladder outlet obstruction in patients with benign prostatic hyperplasia. MATERIAL Between September 2022 and January 2024, a total of 106 patients with benign prostatic hyperplasia were collected from Hongqi Hospital affiliated to Mudanjiang Medical University followed by urodynamic testing. The patients were categorized into three groups based on the International Prostate Symptom Score: mild (45 cases), moderate (36 cases), and severe (25 cases). Thirty-five healthy men were recruited at the hospital as a control group. All patients had blood tests and ultrasound scans. RESULTS Neutrophil-to-lymphocyte ratio, detrusor wall thickness, detrusor muscle elastic modulus, internal gland elastic modulus, intravesical prostatic protrusion, and post-voiding residual volume were significantly correlated with the bladder outlet obstruction stage and showed good diagnostic efficiency (all P<0.05. There was no statistically significant difference observed in the external gland elastic modulus between the experimental group and the control group (P>0.05). CONCLUSIONS The neutrophil-to-lymphocyte ratio, detrusor wall thickness, elastic modulus of the detrusor and glandular gland may hold clinical significance for diagnosing bladder outlet obstruction resulting from benign prostatic hyperplasia. LEVEL OF EVIDENCE: 3

Abstract
PURPOSE OF REVIEW Despite the widespread utilization of 5-alpha reductase inhibitors (5-ARIs) for managing benign prostatic hyperplasia (BPH), certain BPH patients exhibit unresponsiveness to 5-ARIs therapy. This paper provides a comprehensive overview of the current perspectives on the mechanisms of 5-ARIs resistance in BPH patients and integrates potential biomarkers and underlying therapeutic options for 5-ARIs resistance. These findings may facilitate the development of novel or optimize more effective treatment options, and promote personalized medicine for BPH. RECENT FINDINGS The pathways contributing to resistance against 5-ARIs in certain BPH patients encompass epigenetic modifications, shifts in hormone levels, autophagic processes, and variations in androgen receptor structures, and these pathways may ultimately be attributed to inflammation. Promisingly, novel biomarkers, including intravesical prostatic protrusion, inflammatory factors, and single nucleotide polymorphisms, may offer predictive insights into the responsiveness to 5-ARIs therapy, empowering physicians to fine-tune treatment strategies. Additionally, on the horizon, GV1001 and mTOR inhibitors have emerged as potential alternative therapeutic modalities for addressing BPH in the future. After extensive investigation into BPH's pathological processes and molecular landscape, it is now recognized that diverse pathophysiological mechanisms may contribute to different BPH subtypes among individuals. This insight necessitates the adoption of personalized treatment strategies, moving beyond the prevailing one-size-fits-all paradigm centered around 5-ARIs. The imperative for early identification of individuals prone to treatment resistance will drive physicians to proactively stratify risk and adapt treatment tactics in future practice. This personalized medicine approach marks a progression from the current standard treatment model, emerging as the future trajectory in BPH management.

Abstract
Purpose The prevalence of benign prostatic hyperplasia (BPH) in the general Chinese adult male population has risen sharply over the past few decades. Increasing evidence suggests that inflammation plays an important role in the pathogenesis of BPH. To better understand the role of inflammation in the pathogenesis of BPH, we can use the neutrophil-to-lymphocyte ratio (NLR) because it is a simple and effective marker of inflammation and immunity. This study aims to prospectively investigate the association between NLR levels and the prevalence of BPH in a general Chinese adult male population. Patients and Methods This study included a total of 15,783 male participants free from BPH at baseline. NLR was measured according to the complete blood count. BPH was defined as total prostate volume (TPV) ≥30 mL, and TPV was determined by transabdominal ultrasonography. Multivariable Cox proportional hazards models were fitted to calculate hazards ratios (HRs) and corresponding 95% confidence intervals (CIs) for BPH risk with NLR levels. Results During a median follow-up of 2.7 years, 5078 BPH cases were documented. After adjusting for age, body mass index, smoking, alcohol, education, occupation, income, physical activity, total energy intake, personal and family history of disease, and inflammation markers, the multivariable-adjusted HRs of BPH were 1.00 (reference), 1.08 (95% CIs 0.99, 1.17), 1.10 (95% CIs1.02, 1.19), and 1.12 (95% CIs1.03, 1.21), respectively, for participants with NLR in the first, second, third, and fourth quartiles (P for trend <0.01). Conclusion Higher NLR levels were associated with a higher risk of BPH in Chinese adult male population. Our findings support the notion that NLR levels may be an important target for BPH prevention and intervention.

Association of Neutrophil-to-Lymphocyte Ratio, Platelet-to-Lymphocyte Ratio, and Lymphocyte-to-Monocyte Ratio with Benign Prostatic Hyperplasia: A Propensity Score-Matched Analysis. Urol Int 2021; 105:811-816. [PMID: 33508844 DOI: 10.1159/000512894] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 11/04/2020] [Indexed: 11/19/2022]
Abstract
INTRODUCTION The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) have recently been proposed as easily accessible inflammatory biomarkers and as surrogate markers for metabolic disease, cardiovascular disease, and malignancies, including prostate cancer. However, scant studies have investigated the association of NLR, PLR, and LMR with benign prostatic hyperplasia (BPH). METHODS Data from 8,727 middle-aged men who had participated in a health checkup were analyzed. BPH was defined as prostate volume ≥30 mL, International Prostate Symptom Score > 7, and maximal flow rate <15 mL/s. Propensity score matching was considered for 269 men with BPH (cases), and 7,136 men with no BPH (controls), but ultimately, propensity scores were matched at a 2:1 ratio of controls to cases (538 men in the control group and 269 men in the case group). RESULTS After propensity score matching, age, International Index of Erectile Function-5, testosterone, and number of metabolic syndrome component variables were evenly distributed and did not differ significantly between the groups. After matching, PLR and LMR were not significantly different between the 2 groups. However, NLR was significantly higher in the case group than in the control group (median [interquartile range]: 1.4 [1.1; 1.8] vs. 1.5 [1.2; 1.9]; p = 0.024) after matching. CONCLUSION High NLR was significantly associated with the presence of BPH. Our results suggest the possible effect of inflammation on BPH development. A prospective study is needed to investigate the potential role of NLR as a candidate biomarker of BPH.

Low Urin Tract Symptoms 2019; 12:62-67. [PMID: 31523936 PMCID: PMC7004152 DOI: 10.1111/luts.12287] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2019] [Revised: 06/24/2019] [Accepted: 07/26/2019] [Indexed: 12/11/2022]
Abstract
Objective To analyze the association between neutrophil‐to‐lymphocyte ratio (NLR) and intravesical prostatic protrusion (IPP) in men with benign prostatic hyperplasia. Methods Two hundred and fifty men aged >50 years who presented with lower urinary tract symptoms at our institution between 2014 and 2018 were analyzed. Pearson's method was used for analysis of the correlation between NLR and IPP. Multivariate logistic regression analysis was used to identify predictors of IPP. Further analysis according to total prostate volume (TPV) was performed. Results The NLR correlated positively with IPP (Pearson's r = 0.459, P < 0.001) and was an independent predictor of IPP ≥10 mm (odds ratio, 2.95; 95% confidence interval, 1.59–5.47; P = 0.0006). Among the 142 men with prostates <40 cm3, mean NLR was 2.50 ± 0.71 in those with IPP ≥10 mm and 1.71 ± 0.57 in those with IPP < 10 mm (P < 0.001). The NLR differed significantly between those with a prostate <40 cm3 and IPP ≥10 mm and those with a larger prostate and IPP < 10 mm (2.50 ± 0.71 vs 2.07 ± 0.77, respectively; P = 0.020). Conclusions NLR can be used as a surrogate marker for presence of IPP. Its clinical value would be especially important in men with a small prostate gland but high IPP. The NLR seemed to be more strongly correlated with IPP than with TPV.
