Urinary albumin excretion rate (UAER) is a remarkable index reflecting the progression of kidney disease in diabetic subjects. The link between UAER and lipid metabolism is still unclear. The correlation of Apolipoprotein B (ApoB) to albuminuria has been investigated. The National Cholesterol Education Program-Adult Treatment Panel III recommends that clinicians consider non-high-density lipoprotein cholesterol (non-HDL-c) as a surrogate marker for ApoB.
We sought to evaluate the relationship of UAER with lipid profile, especially with non-HDL-c in type 2 diabetic patients without renal dysfunction.
A total of 507 type 2 diabetic patients with normal renal function participated in this study. Demographic and anthropometric data were collected; 24-hour urine samples were collected for UAER measurement. Blood samples were collected for lipid parameters and HbA1c measurement.
The patients with albuminuria had greater levels of non-HDL-c and ApoB. The frequencies of albuminuria among the four quartiles of lipid parameters, ie, triglycerides, total cholesterol, non-HDL-c, and ApoB, demonstrated significantly linearly increasing (P for trend <.01). After adjustment, UAER was significantly correlated with total cholesterol, triglycerides, ApoB, and non-HDL-c but not with low-density lipoprotein cholesterol (LDL-c) or lipoprotein(a) [Lp(a)]. Stepwise regression analysis showed that age (β = .255, P = .000), systolic blood pressure (β = .261, P = .000), non-HDL-c (β = .164, P = .000), and duration of diabetes (β = .105, P = .024) were independently correlated with UAER in diabetic patients without renal dysfunction.
Compared with the lipid parameters of total cholesterol, triglycerides, HDL-c, LDL-c, ApoB, Apolipoprotein A-I (ApoA-I), and Lp(a), non-HDL-c was more closely associated with albuminuria in Chinese type 2 diabetic patients without impaired renal function.
尿白蛋白排泄率(UAER)是反映糖尿病患者肾脏疾病进展的一项重要指标。UAER 与脂代谢之间的关系尚不清楚。已有研究探讨了载脂蛋白 B(ApoB)与白蛋白尿之间的相关性。国家胆固醇教育计划-成人治疗专家组 III 建议临床医生将非高密度脂蛋白胆固醇(non-HDL-c)作为 ApoB 的替代标志物。
我们旨在评估 UAER 与血脂谱的关系,特别是在肾功能正常的 2 型糖尿病患者中非高密度脂蛋白胆固醇(non-HDL-c)与 UAER 的关系。
共纳入 507 例肾功能正常的 2 型糖尿病患者,收集患者的人口统计学和人体测量学数据;收集 24 小时尿液样本测量 UAER;采集血样测量血脂参数和糖化血红蛋白(HbA1c)。
白蛋白尿患者的 non-HDL-c 和 ApoB 水平更高。在血脂参数的四个四分位区间(即三酰甘油、总胆固醇、non-HDL-c 和 ApoB)中,白蛋白尿的发生频率呈明显线性增加(趋势 P<.01)。校正后,UAER 与总胆固醇、三酰甘油、ApoB 和 non-HDL-c 显著相关,但与低密度脂蛋白胆固醇(LDL-c)或脂蛋白(a)[Lp(a)]无关。逐步回归分析显示,年龄(β=0.255,P=0.000)、收缩压(β=0.261,P=0.000)、non-HDL-c(β=0.164,P=0.000)和糖尿病病程(β=0.105,P=0.024)与肾功能正常的糖尿病患者的 UAER 独立相关。
与总胆固醇、三酰甘油、高密度脂蛋白胆固醇(HDL-c)、低密度脂蛋白胆固醇(LDL-c)、ApoB、载脂蛋白 A-I(ApoA-I)和 Lp(a)等血脂参数相比,non-HDL-c 与中国肾功能正常的 2 型糖尿病患者的白蛋白尿更为密切相关。
