Infertility & Sexual Dysfunction(구연) (NP-025) 호중구 대 림프구비와 발기부전과의 연관성 경상대학교 의과대학 비뇨기과학교실 최세민, 최재휘, 이신우, 제성욱, 현재석, 정기현, 화정석 Introduction and Objective Our study aimed to evaluate the association between the inflammatory biomarkers and erectile dysfunction (ED). Methods We retrospectively investigated men’s health checkup data from July 2011 to October 2018 at our health promotion center. The Baseline data of age, body mass index (BMI), prostate specific antigen (PSA) was investigated and also Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) was investigated as inflammatory biomarkers. Univariate and multivariate logistic regression analysis was performed to identify independent predictors of ED. Results Total 791 subjects were assessed in this study. The mean age was 49.87 years (Table 1). In multivariate analysis, NLR was identified as an independent predictor for ED (HR 1.277, P = 0.024) (Table 2). Conclusions The NLR are correlated with a diagnosis of ED, and this ratios could serve as practical parameters. keywords : biomarkers, neutrophil-to-lymphocyte ratio, erectile dysfunction
