Nephrotic syndrome is associated with an increased risk of atherosclerosis and endothelial dysfunction. The aim of this work was to evaluate serum adiponectin and fetuin-A levels in children with idiopathic nephrotic syndrome. The study was carried out on 70 children, divided into 2 groups. Group I included 35 children with steroid responsive idiopathic nephrotic syndrome (15 in relapse and 20 in remission) and group II included 35 apparently healthy children served as control with matched age and sex. The results showed significantly higher adiponectin with significantly lower fetuin-A in patients than controls and in relapse group as compared to both remission and control groups. There was a significant negative correlation between adiponectin and fetuin-A.
Both adiponectin and fetuin-A may be useful markers of activity of nephrotic syndrome. Increased serum adiponectin levels in relapse compared to remission might be the reflection of a compensatory response to nephrotic state characterized by massive proteinuria, hypoalbuminemia and hyperlipidemia. Low concentration of fetuin-A in relapsed children of NS may depend on proteinuria.
肾病综合征与动脉粥样硬化和内皮功能障碍风险增加相关。本研究旨在评估特发性肾病综合征患儿血清脂联素和胎球蛋白-A水平。该研究对70名儿童进行,分为两组。第一组包括35名激素敏感型特发性肾病综合征患儿(15名处于复发期,20名处于缓解期),第二组包括35名年龄和性别匹配的健康儿童作为对照组。结果显示,与对照组相比,患者的脂联素显著升高,胎球蛋白-A显著降低;与缓解期组和对照组相比,复发组的脂联素显著升高,胎球蛋白-A显著降低。脂联素与胎球蛋白-A之间存在显著负相关。
脂联素和胎球蛋白-A都可能是肾病综合征活动的有用标志物。与缓解期相比,复发期血清脂联素水平升高可能是对以大量蛋白尿、低白蛋白血症和高脂血症为特征的肾病状态的一种代偿反应。肾病综合征复发患儿胎球蛋白-A浓度低可能与蛋白尿有关。
