Correlation of Asymmetric Dimethylarginine With Podocytopathy Markers in Diabetic Kidney Disease Patients.
Background: Diabetic kidney disease (DKD) is the leading cause of end-stage kidney disease, and podocytopathy is an early manifestation of DKD characterized by the urinary excretion of podocyte-specific proteins, such as nephrin and podocin. Asymmetric dimethylarginine (ADMA)-a biomarker of endothelial dysfunction-is associated with progressive kidney dysfunction. However, the mechanism of endothelial dysfunction in DKD progression is unclear. The aim of this study was to investigate the correlations of ADMA levels with nephrin, podocin, and the podocin:nephrin ratio (PNR) in DKD patients.
Methods: A cross-sectional study of 41 DKD outpatients was performed in two hospitals in Jakarta from April-June 2023. The collected data included the subjects' characteristics, histories of disease and medication, and relevant laboratory data. Serum ADMA was measured using liquid chromatography, while urinary podocin and nephrin were measured using the enzyme-linked immunosorbent assay (ELISA) method. A correlation analysis was performed to evaluate the correlation of ADMA with nephrin, podocin, and PNR. Regression analysis was performed to determine confounding factors.
Results: The mean value of ADMA was 70.2 (SD 17.2) ng/mL, the median for nephrin was 65 (20-283 ng/mL), and the median of podocin was 0.505 (0.433-0.622) ng/mL. ADMA correlated significantly with nephrin (r = 0.353, p = 0.024) and PNR (r = -0.360, p = 0.021), but no correlation was found between ADMA and podocin (r = 0.133, p = 0.409). The multivariate analysis showed that body mass index was a confounding factor.
Conclusion: This study revealed weak positive correlations between ADMA and urinary nephrin and between ADMA and PNR. No correlation was found between ADMA and urinary podocin.
期刊介绍：
International Journal of Nephrology and Renovascular Disease is an international, peer-reviewed, open-access journal focusing on the pathophysiology of the kidney and vascular supply. Epidemiology, screening, diagnosis, and treatment interventions are covered as well as basic science, biochemical and immunological studies. In particular, emphasis will be given to: -Chronic kidney disease- Complications of renovascular disease- Imaging techniques- Renal hypertension- Renal cancer- Treatment including pharmacological and transplantation- Dialysis and treatment of complications of dialysis and renal disease- Quality of Life- Patient satisfaction and preference- Health economic evaluations. The journal welcomes submitted papers covering original research, basic science, clinical studies, reviews & evaluations, guidelines, expert opinion and commentary, case reports and extended reports. The main focus of the journal will be to publish research and clinical results in humans but preclinical, animal and in vitro studies will be published where they shed light on disease processes and potential new therapies and interventions.
