摘要

介绍:两个新的公式,马丁-霍普金斯和桑普森公式,最近发展克服了计算低密度脂蛋白胆固醇的弗里德瓦尔德公式的缺点。我们的目的是比较两种配方与载脂蛋白B (apoB)的一致性,载脂蛋白B是LDL颗粒数量的替代标记物。材料与方法:对1179例就诊于Bruges AZ St-Jan医院进行心血管风险评估的患者的血脂数据进行研究,确定并比较Friedewald、Martin-Hopkins和Sampson配方与免疫比浊法测定的载脂蛋白ob浓度的相关性和一致性。结果:在整个数据集和低ldl -胆固醇< 1.8 mmol/L的患者中,Martin-Hopkins公式与载脂蛋白ob的相关系数显著高于Friedewald公式。根据高甘油三酯血症患者(2-4.5 mmol/L)载脂蛋白ob的人群等效阈值进行治疗组分类时,Martin-Hopkins和Sampson公式的ldl -胆固醇一致性均> 70%,其中Martin-Hopkins公式的一致性最高(75.6%),而Friedewald公式的一致性最高(60.5%)。结论:与Friedewald公式相比,Martin-Hopkins公式(在较小程度上,Sampson公式)与LDL颗粒数量的关系更为密切。这一点,再加上弗里德瓦尔德公式准确性较低的文献证据,是一个从弗里德瓦尔德公式转向一个修改的、改进的公式的理由。

Concordance of apolipoprotein B concentration with the Friedewald, Martin-Hopkins, and Sampson formulas for calculating LDL cholesterol.

Concordance of apolipoprotein B concentration with the Friedewald, Martin-Hopkins, and Sampson formulas for calculating LDL cholesterol.

Concordance of apolipoprotein B concentration with the Friedewald, Martin-Hopkins, and Sampson formulas for calculating LDL cholesterol.

Concordance of apolipoprotein B concentration with the Friedewald, Martin-Hopkins, and Sampson formulas for calculating LDL cholesterol.

Introduction: Two new formulas, the Martin-Hopkins and the Sampson formula, were recently developed to overcome shortcomings of the Friedewald formula for calculating LDL-cholesterol. We aimed to compare the concordance of the two formulas with apolipoprotein B (apoB), a surrogate marker of the number of LDL particles.

Materials and methods: In a study of serum lipid data of 1179 patients who consulted the AZ St-Jan Hospital Bruges for cardiovascular risk assessment, the correlation and concordance of the Friedewald, Martin-Hopkins and Sampson formulas with apoB concentration, measured by immunonephelometry, were determined and compared.

Results: The Martin-Hopkins formula showed significantly higher correlation coefficient than the Friedewald formula with apoB in the entire dataset and in patients with low LDL-cholesterol < 1.8 mmol/L. Both Martin-Hopkins and Sampson formulas yielded > 70% concordance of LDL-cholesterol with regard to treatment group classification based on population-equivalent thresholds of apoB in hypertriglyceridemic patients (2-4.5 mmol/L), with the highest concordance (75.6%) obtained using Martin-Hopkins formula vs. 60.5% with Friedewald formula.

Conclusion: The Martin-Hopkins (and, to a lesser extent, Sampson) formula is more closely associated with the number of LDL particles than Friedewald formula. This, in combination with literature evidence of lesser accuracy of the Friedewald formula, is an argument to switch from Friedewald to a modified, improved formula.
