    Correlation between serum lipoprotein associated phospholipase A2 level and renal damage in elders with type 2 diabetes mellitus

    • 摘要: 目的 旨在调查老年2型糖尿病(type 2 diabetes mellitus,T2DM)患者血清脂蛋白相关性磷脂酶A2(lipoprotein associated phospholipase 2,Lp-PLA2)水平与糖尿病肾脏疾病(diabetic kidneydisease,DKD)肾脏损害的相关性。方法 共招募了118例老年T2DM患者,并依据尿白蛋白/尿肌酐比值(urine albumin to creatinine ratio,UACR)分为3组:糖尿病(diabetes,DM)组52例,UACR<30mg/g;DKD1组38例,30 mg/g ≤ UACR<300 mg/g;DKD2组28例,UACR ≥ 300 mg/g。比较3组受试者临床指标、肾功能和Lp-PLA2水平之间差异,分析Lp-PLA2与临床指标之间的相关性。采用Lo-gistic回归分析筛选老年T2DM患者DKD发生的危险因素。结果 与单纯DM组相比,DKD1组和DKD2组受试者Lp-PLA2水平明显升高DM组:(215.7±32.9)ng/mL;DKD1组:(266.9±46.7)ng/mL;DKD2组:(294.2±76.1)ng/mL,且随着DKD分期的增加,Lp-PLA2水平逐渐升高,DKD2组Lp-PLA2水平高于DKD1组DKD1组:(266.9±46.7)ng/mL;DKD2组:(294.2±76.1)ng/mL。Pearson相关分析显示,老年T2DM患者Lp-PLA2水平与三酰甘油(triacylglycerin,TC)(r=0.27,P=0.01)、低密度脂蛋白胆固醇(low density lipoprotein cholesterol,LDL-C)(r=0.47,P<0.01)和UACR(r=0.54,P<0.01)呈正相关关系;与估算肾小球滤过率(estimated glomerular filtration rate,eGFR)(r=-0.61,P<0.01)呈负相关关系。Logistic回归分析显示,体重指数(body mass index,BMI)、糖化血红蛋白(glycosylated hemoglobin,HbA1c)和Lp-PLA2是预测老年T2DM患者DKD的危险因素。结论 Lp-PLA2或参与了老年T2DM患者DKD的发生、发展,定期监测Lp-PLA2对预防和治疗老年T2DM患者DKD有着重要的临床意义。

       

      Abstract: Objective To explore the correlation between serum lipoprotein associated phospholipase A2 (Lp-PLA2) and renal damage of diabetic kidney disease (DKD) in elders with type 2 diabetes mellitus (T2DM). Methods A total of 118 T2DM elders were recruited and divided into three groups according to urinary albumin/creatinine ratio. That is, group DM, n=52, urine albumin to creatinine ratio (UACR) <30 mg/g;group DKD1, n=38, 30 mg/gn=28, UACR > 300 mg/g. The differences of clinical parameters,renal function and Lp-PLA2 level were compared among three groups. And the correlation between Lp-PLA2 and clinical parameters was analyzed. Logistic regression analysis was performed for screening the risk factors of DKD in T2DM elders. Results Compared with simple DM group, the level of Lp-PLA2 was significantly higher in group DKD1/DKD2 DM group:(215.7±32.9) ng/mL;DKD1 group:(266.9±46.7) ng/mL;DKD2 group:(294.2±76.1) ng/mL. With an advancing stage of diabetic nephropathy, the level of Lp-PLA2 rose gradually and the level of Lp-PLA2 was higher in group DKD2 than that in group DKD1 DKD1 group:(266.9±46.7) ng/mL;DKD2 group:(294.2±76.1) ng/mL. Pearson's correlation analysis revealed that the level of Lp-PLA2 was correlated positively with total cholesterol (TC,r=0.27,P=0.01), low-density lipoprotein-cholesterol (LDL-C,r=0.47,P<0.01) and UACR (r=0.54,P<0.01) and negatively with estimated glomerular filtration rate (eGFR,r=-0.61,P<0.01). Logistic regression analysis indicated that body mass index (BMI), HbA1c and Lp-PLA2 were the risk factors for predicting DKD in T2DM elders. Conclusion Lp-PLA2 is probably involved in the occurrence and development of DKD. And regular monitoring of Lp-PLA2 has important clinical implications for preventing and treating DKD in T2DM elders.
