Abstract

Premature atherosclerosis is a major cause of morbidity and mortality in end-stage renal disease patients. Dyslipidemia and increased oxidative stress contribute to premature atherogenesis in these patients. The dyslipidemia of end-stage renal disease consists of both quantitative and qualitative abnormalities in serum lipoproteins. Qualitative changes include hypertriglyceridemia (increased remnant lipoproteins), low high-density lipoprotein-cholesterol, and increased lipoprotein (a). In addition to quantitative changes, lipoproteins in end-stage renal disease undergo compositional and qualitative changes that make them pro-atherogenic, such as various modifications of apolipoprotein B, including oxidation, and modification by advanced glycation end-products. The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors and low-dose fibrates could be effective therapies for lipid disorders. The best evidence for increased oxidative stress in end-stage renal disease is the demonstration of increased plasma F2-isoprostanes. Confirmation of the positive findings with high-dose alpha-tocopherol in the Secondary Prevention with Antioxidants of Cardiovascular Disease in End-stage Renal Disease Study is urgently needed. Clinical trials with statins and other drugs that improve dyslipidemia also need to be undertaken. These therapies could clearly lead to a reduction in cardiovascular morbidity and mortality in these patients.

摘要

动脉粥样硬化过早发生是终末期肾病患者发病和死亡的主要原因。血脂异常和氧化应激增加促使这些患者过早发生动脉粥样硬化。终末期肾病的血脂异常包括血清脂蛋白的数量和质量异常。质量变化包括高甘油三酯血症(残余脂蛋白增加)、低高密度脂蛋白胆固醇以及脂蛋白(a)增加。除数量变化外,终末期肾病患者的脂蛋白还会发生组成和质量变化,使其具有致动脉粥样硬化性,如载脂蛋白B的各种修饰,包括氧化以及晚期糖基化终产物的修饰。3-羟基-3-甲基戊二酰辅酶A还原酶抑制剂和低剂量贝特类药物可能是治疗脂质紊乱的有效疗法。终末期肾病患者氧化应激增加的最佳证据是血浆F2-异前列腺素增加。迫切需要在终末期肾病患者心血管疾病抗氧化剂二级预防研究中用高剂量α-生育酚证实阳性结果。还需要开展使用他汀类药物和其他改善血脂异常药物的临床试验。这些疗法显然可以降低这些患者的心血管发病率和死亡率。
