Lipoprotein(a) (Lp(a)) is a genetic risk factor for cardiovascular disease (CVD) and is associated with the induction and sustaining of atherosclerotic cardiovascular diseases (ASCVD). Since 2008 Lp(a) along with progressive CVD has been approved as an indication for regular lipoprotein apheresis (LA) in Germany. The German Lipoprotein Apheresis Registry (GLAR) has been initiated to provide statistical evidence for the assessment of extracorporeal procedures to treat dyslipidemia for both LDL-cholesterol (LDL-C) and Lp(a). The GLAR now allows prospective investigations over a 5-year period about annual incidence rates of cardiovascular events. Here Lp(a) patients (LDL-C < 100 mg/dl; Lp(a) > 60 mg/dl or >120 nmol/l) showed the same reduction of major coronary (83%) and non-coronary events (63%) as had been formerly shown in the Pro(a)LiFe study. However, Lp(a) is not only an apolipoprotein(a) (apo(a)) and LDL-C containing particle, which is covalently bound to a LDL-C core by a disulphide bridge. The composition of this particle, inter alia containing oxidized phospholipids, gives pro-atherosclerotic, pro-inflammatory, and pro-thrombotic properties, inducing atherosclerotic processes mainly in the arterial wall. However, recent investigations have shown that a reduction of inflammatory settings without LDL-C or Lp(a) reduction may reduce ASCVD events. Lipoprotein apheresis (LA) could not only reduce LDL-C and Lp(a) in parallel, but also different inflammatory and coagulation parameters. In summary lipoprotein apheresis is not only anti-atherosclerotic, but also anti-inflammatory and anti-thrombotic and therefore an ideal treatment option with respect to the shown reduction of major adverse coronary events (MACE) and major adverse non-coronary events (MANCE) by reducing Lp(a) levels.
脂蛋白(a)[Lp(a)]是心血管疾病(CVD)的遗传风险因素,与动脉粥样硬化性心血管疾病(ASCVD)的发生和持续发展相关。自2008年起,在德国,Lp(a)连同进展性CVD已被批准作为定期脂蛋白分离置换法(LA)的适应证。德国脂蛋白分离置换法登记处(GLAR)已启动,目的是为评估用于治疗低密度脂蛋白胆固醇(LDL-C)和Lp(a)异常血脂血症的体外治疗程序提供统计依据。GLAR现在允许对心血管事件的年发病率进行为期5年的前瞻性调查。在此,Lp(a)患者(LDL-C<100mg/dl;Lp(a)>60mg/dl或>120nmol/l)显示出与之前Pro(a)LiFe研究中相同程度的主要冠状动脉事件(83%)和非冠状动脉事件(63%)的减少。然而,Lp(a)不仅是一种载脂蛋白(a)[apo(a)]和含LDL-C的颗粒,它通过二硫键与LDL-C核心共价结合。该颗粒的组成,尤其是含有氧化磷脂,赋予其促动脉粥样硬化、促炎和促血栓形成特性,主要在动脉壁诱导动脉粥样硬化过程。然而,最近的研究表明,在不降低LDL-C或Lp(a)的情况下减少炎症状态可能会减少ASCVD事件。脂蛋白分离置换法(LA)不仅可以同时降低LDL-C和Lp(a),还可以降低不同的炎症和凝血参数。总之,脂蛋白分离置换法不仅具有抗动脉粥样硬化作用,还具有抗炎和抗血栓形成作用,因此,就通过降低Lp(a)水平显示出的主要不良冠状动脉事件(MACE)和主要不良非冠状动脉事件(MANCE)的减少而言,它是一种理想的治疗选择。
