血尿酸、尿微量白蛋白水平与2型糖尿病颈动脉内膜病变的关系

目的探讨血尿酸、尿微量白蛋白水平与2型糖尿病大血管病变的关系。方法2型糖尿病患者97例,依照尿白蛋白排泄率(UAER)分成2组:UAER20～200μg/min为A组,63例;UAER≥200μg/min为B组,34例;根据血尿酸水平是否升高分为C组(59例)和D组(38例)。记录比较各组病程、血尿酸(BUA)、空腹血糖(FBG)、甘油三脂(TG)、胆固醇(TC)、低密度脂蛋白(LDL)、高密度脂蛋白(HDL)、尿白蛋白排泄率(UAER)、颈动脉内膜-中层厚度(IMT)水平差异,比较血尿酸、尿微量蛋白水平及糖尿病患者颈动脉IMT三者相关性关系。结果四组TG、TC、LDL及HDL水平比较,差异无统计学意义(P>0.05)。A、C组病程、UA、UAER、FBG水平及IMT均明显高于B、D组(P<0.05)。A组与C组、B组与D组病程、UA、UAER、FBG水平及IMT组间比较,差异无统计学意义(P>0.05)。多元回归分析显示病程、UA、UAER与颈动脉IMT有显著性正相关,UA与UAER呈显著性相关。结论糖尿病患者大血管病变与病程、血UA、UREA水平密切相关,因此血UA、UREA水平可用于早期预测糖尿病大血管...

Association of urinary albumin excretion rate and hyperuricemia with macrovascular atherosclerosis in type 2 diabetic patients

Objective To investigate the association of urinary albumin excretion rate (UAER) and hyperuricemia with macrovascular atherosclerosis in type 2 diabetic patients. Methods Ninety-seven type 2 diabetic patients were divided into two groups according to the UAER, namely group A with UAER between 20 and 200 μg/min (n=63) and group B with UAER ≥200 μg/min (n=34); the patients were also classified into hyperurieemia group (group C, n=59) and normal blood uric acid (BUA) group (group D, n=38). The disease course, BUA, fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoproteins (HDL), UAER and arteria carotis intima-media thickness (IMT) were determined in these patients. The relationship of UAER and hyperuricemia with carotid arterial IMT was analyzed statistically. Results The levels of TG, TC, LDL and HDL showed no significant differences between the 4 groups (P>0.05). The disease course, BUA, UAER, and FBG levels and IMT in groups A and C were significantly higher than those in groups C and D (P<0.05), but no such differences were found between groups A and C or between groups B and D (P>0.05). Arotid arterial IMT was independently correlated to the disease course, BUA and UAER (r=0.201, 0.1999, 0.211, respectively, P<0.05), and a significant positive correlation was noted between BUA and UAER (r=0.221, P<0.05). Conclusion Macrovascular atherosclerosis in type 2 diabetic patients is significantly correlated to the disease course, BUA and UAER levels, which can be used to evaluate and predict macrovascular atheroselerosis in type 2 diabetic patients,
