Lipoprotein (a) [Lp(a)] and its measurement, structure and function, the impact of ethnicity and environmental factors, epidemiological and genetic associations with vascular disease, and new prospects in drug development have been extensively examined throughout this Thematic Review Series on Lp(a). Studies suggest that the kidney has a role in Lp(a) catabolism, and that Lp(a) levels are increased in association with kidney disease only for people with large apo(a) isoforms. By contrast, in those patients with large protein losses, as in the nephrotic syndrome and continuous ambulatory peritoneal dialysis, Lp(a) is increased irrespective of apo(a) isoform size. Such acquired abnormalities can be reversed by kidney transplantation or remission of nephrosis. In this Thematic Review, we focus on the relationship between Lp(a), chronic kidney disease, and risk of cardiovascular events.
脂蛋白 (a)[Lp(a)]及其检测、结构与功能、种族和环境因素的影响、与血管疾病的流行病学和遗传学关联,以及药物研发的新前景,这些都是本系列关于 Lp(a) 的专题评论所广泛探讨的内容。研究表明,肾脏在 Lp(a) 的分解代谢中起作用,而且只有携带大载脂蛋白 (apo)a 异构体的人,其 Lp(a) 水平才会随着肾脏疾病的发生而升高。相比之下,在那些存在大量蛋白丢失的患者中,例如肾病综合征和持续不卧床腹膜透析患者,无论 apo(a) 异构体大小如何,Lp(a) 均会升高。这些获得性异常可通过肾移植或肾病缓解得到逆转。在本专题评论中,我们重点关注 Lp(a)、慢性肾脏病与心血管事件风险之间的关系。
