  • Title: Dimethylarginines as risk markers of atherosclerosis and chronic kidney disease in children with nephrotic syndrome.
    Author: Hyla-Klekot L, Bryniarski P, Pulcer B, Ziora K, Paradysz A.
    Journal: Adv Clin Exp Med; 2015; 24(2):307-14. PubMed ID: 25931365.
    Abstract:
    BACKGROUND: Nephrotic syndrome in children is commonly associated with dyslipidemia, which is considered a risk factor for endothelial dysfunction and atherosclerosis. Recently new markers of endothelial dysfunction, such as asymmetric dimethylarginine (ADMA), have gained importance. Another L-arginine derivative--symmetric dimethylarginine (SDMA)--may reflect the glomerular filtration rate (GFR). OBJECTIVES: The main aim of this study was to assess ADMA as a marker of atherosclerosis. Secondly, SDMA was examined for GFR assessment. MATERIAL AND METHODS: The study involved 32 children with nephrotic syndrome. Several parameters were examined in the remission and relapse phases of nephrotic syndrome, including ADMA, SDMA, cholesterol, triglycerides and GFR. RESULTS: In the relapse phase there was a negative correlation between ADMA and lipids (cholesterol and triglycerides). In both phases SDMA was negatively correlated with GFR. CONCLUSIONS: The role of ADMA as a marker for endothelial dysfunction is not significant. SDMA may be utilized to monitor GFR in children with nephrotic syndrome.
