糖代谢异常者541例尿白蛋白5年随访分析

Analysis of 5-year follow-up on Microalbuminuria in Patients with Disorder of Glucose Metabolism

为了探讨影响糖代谢异常者尿微量白蛋白的因素 ,选取 1 994年口服葡萄糖耐量试验 (OGTT)筛查时 ,糖代谢异常但尿白蛋白排泄率 (UAER) <2 0 μg/min的患者共 5 41例 ,5年后复查 1 994年曾经检测过的所有项目 ;排除急性感染及其他肾脏疾病、冠心病心绞痛、心肌梗死、心功能不全、脑卒中患者。结果 :1 ) 5年后UAER≥ 2 0 μg/min组共1 1 3例 ,发生率为 2 0 .9% ,其中糖尿病占 61 .9% ,空腹血糖受损 (IFG)和糖耐量减低 (IGT)分别为 1 3 .3 %、1 7.7% ,IFG、IGT同时存在的占 7.1 % ;2 )UAER≥ 2 0 μg/min组 ,高血压病程、血压、BMI、血糖、血脂、空腹胰岛素水平均显著高于UAER正常组 (n =42 8) (P =0 .0 0 0～ 0 .0 3 3 ) ;3 )UAER≥ 2 0 μg/min组 ,5年后各项临床指标与基线值比较 ,高血压病程、血压、吸烟量较前有显著增高 (P =0 .0 0 1～ 0 .0 45 ) ;多元逐步回归分析显示 ,UAER与收缩压、OGTT 2h血糖呈显著正相关 ,P分别为 0 .0 0 0和 0 .0 1 4。提示 :异常的尿白蛋白排泄率与高血压、高血糖明显相关 ,提出及早控制血压。

To explore the relative importance of risk factors on microalbuminuria in the patients with disorder of glucose metabolism, a 5 year follow up of 541 patients with disorder of glucose metabolism, aged (56±11) years at baseline with UAER<20 μg/min was carried out. The cases of UAER ≥20 μg/min were 20.9% (113/541). Key risk factors included hypertensive duration, blood pressure, or smoking. Independent risk factors, as assessed by multiple stepwise regression effects, were SBP ( P =0.000), OGTT 2 h blood glucose ( P =0.014). Microalbuminuria is significantly correlated with blood pressure and hyperglycemia, which suggests that early intervention is necessary.
