摘要
脂蛋白a[Lp(a)]是由载脂蛋白A[Apo(a)]和载脂蛋白B[Apo(B)]通过二硫键连接构成的LDL样颗粒脂蛋白分子.因编码Apo(a)的LPA基因存在基因多态性,导致不同人群个体Lp(a)分子大小存在高度的异质性.已有研究表明高血清Lp(a)水平是心血管病的危险因素之一和预测指标,最近的研究提示降低Lp(a)水平的治疗策略可减少高Lp(a)水平者的心血管病事件发生率.目前Lp(a)临床检测存在方法多样、参考品与待测样品Lp(a)分子异质性问题.参考物质和检测方法的标准化对于Lp(a)在临床中的广泛应用以及明确其在心血管病危险评估中的价值有重要意义.
Lipoprotein(a) [ Lp (a) ] is an LDL-like molecule consisting of an apolipoprotein (B) [ Apo(B) ] particle attached by a disulphide bridge to apolipoprotein(a) [ Apo(a) ]. Because of the LPA gene polymorphisms, there exists Lp (a) molecular heterogeneity in the human population. Recently, several observations have pointed out that elevated serum Lp (a) levels may be an independent risk factor of cardiovascular disease and an predictive indicator of cardiovascular disease. Recent findings suggest that Lp ( a) -lowering therapy might be beneficial in patients with high Lp(a) levels. Currently, there are some problems in Lp(a) assay,including clinically diverse methods, the Lp (a) molecular heterogeneity between reference materials and test samples. Standardization of the Lp (a) reference reagents and measurement methods may be helpful for the wide application of Lp(a) in clinical medicine and be helpful for assuring the role of Lp(a) as an independent risk factor and predictive indicator of cardiovascular diseases.
