摘要:

目的 分析特定疾病状态下脂蛋白(a)[Lp(a)]质量浓度和颗粒浓度检测结果的相关性。方法 选取2018年9月—2019年8月复旦大学附属中山医院住院患者581例,其中男406例、女175例,年龄(63.59±14.52)岁,按照疾病类型分为冠心病组(133例)、肝癌组(76例)、糖尿病组(192例)和慢性肾脏病组(180例)。以同期体检健康者200名为健康对照组,其中男125名、女75名,年龄(61.84±5.50)岁。检测所有研究对象Lp(a)颗粒浓度和质量浓度。采用Spearman相关分析评价各组Lp(a)颗粒浓度和质量浓度的相关性;比较各组Lp(a)颗粒浓度和质量浓度阳性率差异;采用Passing-Bablok回归分析和Bland-Altman偏移分析评估各组通过颗粒浓度转换的质量浓度和直接检测得到的质量浓度的一致性。结果 各组Lp(a)颗粒浓度和质量浓度相关性较好(r=0.948 7,P<0.05),其中冠心病组Lp(a)颗粒浓度和质量浓度相关性最高(r=0.976 3,P<0.05),肝癌组相关性最低(r=0.863 2,P<0.05)。糖尿病组、慢性肾脏病组Lp(a)颗粒浓度和质量浓度阳性率差异有统计学意义(P<0.05),健康对照组、肝癌组、冠心病组Lp(a)颗粒浓度和质量浓度阳性率差异无统计学意义(P>0.05)。各组通过Lp(a)颗粒浓度转换的质量浓度与直接检测得到的Lp(a)质量浓度的95%一致性界限均>1/2允许总误差。结论 Lp(a)颗粒浓度和质量浓度有一定的相关性。特定疾病(冠心病、肝癌、糖尿病、慢性肾脏病)患者和健康对照者Lp(a)颗粒浓度和质量浓度阳性率差异不同。通过Lp(a)颗粒浓度转换的质量浓度与直接检测得到的Lp(a)质量浓度的差异超过了临床可接受范围,在临床实践中不建议将Lp(a)颗粒浓度和质量浓度进行转换。

Abstract:

Objective To analyze the results of lipoprotein(a)[Lp(a)] mass concentration and particle concentration in certain disease states. Methods A total of 581 inpatients from September 2018 to August 2019 in Zhongshan Hospital of Fudan University were enrolled,which included 406 males and 175 females,aged (63.59±14.52) years old. There were 133 cases in coronary heart disease group,76 cases in hepatocarcinoma group,192 cases in diabetes group and 180 cases in chronic kidney disease group. Totally,200 healthy subjects were enrolled as well,which included 125 males and 75 females,aged (61.84±5.50) years old. The particle concentration and mass concentration of Lp(a) were determined,and the correlation and positive rate difference between particle and mass concentration in disease groups and healthy control group were analyzed by Spearman correlation analysis. Passing-Bablok regression analysis and Bland-Altman bias evaluation were used to analyze the consistency between the mass concentration calculated by particle concentration and the mass concentration determined directly. Results The correlation between Lp(a) particle concentration and mass concentration was good(r=0.948 7,P<0.05),the highest in coronary heart disease group(r=0.976 3,P<0.05),and the lowest in hepatocarcinoma group(r=0.863 2,P<0.05). The positive rates of particle concentration and mass concentration in chronic kidney disease group and diabetes group had statistical significance(P<0.05). There was no statistical significance in the positive rates of particle concentration and mass concentration among coronary heart disease group,hepatocarcinoma group and healthy control group(P>0.05). The 95% agreement margin between mass concentration calculated by particle concentration and mass concentration determined directly exceeded 1/2 of the allowable total error. Conclusions There is a certain correlation between the particle concentration of Lp(a) and its mass concentration. In different disease groups(coronary heart disease,hepatocarcinoma,diabetes and chronic kidney disease) and healthy control group,the positive rates between Lp(a) particle and mass concentrations are different. The difference between the mass concentration calculated by particle concentration and mass concentration determined directly exceeds the clinically acceptable range,and it is not recommended to convert the Lp(a) particle concentration and mass concentration in clinical practice.
