Abstract

Traditional risk factors such as hypertension, diabetes, dyslipidemia, obesity and metabolic syndrome, as well as additional nontraditional risk factors, can damage the kidney directly and by promoting intrarenal atherogenesis. Evidence indicates that increased oxidative stress and inflammation may mediate most of the effects of risk factors on the kidney. Clinical studies have demonstrated a relationship between oxidative stress and inflammatory biomarkers, and a few studies indicate an inverse correlation of oxidative stress biomarkers with estimated glomerular filtration rate (eGFR). Further, surrogate indexes of atherosclerosis such as intima-media thickness and aortic pulse wave velocity have been demonstrated to be related to plasma concentrations of markers of endothelial activation, inflammation and fibrosis in patients with different stages of chronic kidney disease (CKD). Moreover, plasma concentrations of high-sensitivity C-reactive protein have been shown to be increased and related to left ventricular mass in CKD individuals having left ventricular hypertrophy. In contrast, in these patients, decreases in fetuin-A plasma levels have been reported. Considering the complex background of the pathophysiological changes characterizing CKD patients, we can consider cardiovascular disease a multifactorial complication of CKD.

摘要

传统危险因素,如高血压、糖尿病、血脂异常、肥胖和代谢综合征,以及其他非传统危险因素,可直接损害肾脏,并通过促进肾内动脉粥样硬化而损害肾脏。有证据表明,氧化应激和炎症增加可能介导了危险因素对肾脏的大部分影响。临床研究已证实氧化应激与炎症生物标志物之间存在关联,一些研究表明氧化应激生物标志物与估算肾小球滤过率(eGFR)呈负相关。此外,在慢性肾脏病(CKD)不同阶段的患者中,动脉粥样硬化的替代指标,如内膜中层厚度和主动脉脉搏波速度,已被证明与内皮激活、炎症和纤维化标志物的血浆浓度有关。此外,在患有左心室肥厚的CKD个体中,高敏C反应蛋白的血浆浓度已被证明升高且与左心室质量有关。相反,在这些患者中,已报道胎球蛋白-A血浆水平降低。考虑到CKD患者病理生理变化的复杂背景,我们可将心血管疾病视为CKD的多因素并发症。
