摘 要:目的探讨Ⅰ、Ⅱ级原发性高血压患者糖化血红蛋白(HbA1c)与早期肾损害的关系。方法选择2011年8月~2012年7月福建医科大学附属第一医院首次就诊未治疗的Ⅰ、Ⅱ级原发性高血压患者286例,选择同期健康体检者82例为对照组。根据HbA1c水平将高血压患者分为HbA1c升高组(HbA1c≥6%,134例)和HbA1c正常组(HbA1c<6%,152例)。分别比较三组肾功能相关指标尿微量白蛋白(UAlb)、血肌酐(Scr)、尿素氮(BUN)、肾小球滤过率(GFR)和尿酸(UA)。应用Spearman相关分析及多元线性逐步回归分析探讨HbA1c对高血压患者早期肾损害的预测价值。结果 3组间年龄、性别构成比、体重指数、三酰甘油(TG)、总胆固醇(TCHO)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、空腹血糖(FPG)等指标差异无统计学意义(P>0.05)。原发性高血压患者中,HbA1c升高组UAlb水平明显高于HbA1c正常组(15.0mg/L比11.0 mg/L,P<0.05),但两组高血压病程(5.0年比5.0年)、收缩压(SBP)[(143.5±10.6)mm Hg比(143.9±10.8)mm Hg]、舒张压(DBP)[(83.9±8.7)mm Hg比(83.2±8.4)mm Hg]、Scr[(76.6±25.1)μmol/L比(70.8±19.9)μmol/L]、BUN[(5.4±2.5)mmol/L比(4.9±1.5)mmol/L]、UA[(346.6±110.7)μmol/L比(330.6±90.9)μmol/L]及GFR[(105.0±31.5)mL/min比(105.8±31.3)mL/min]水平比较差异均无统计学意义(均P>0.05)。而UAlb、Scr、BUN、UA、GFR水平在HbA1c正常组与对照组间差异无统计学意义(均P>0.05)。Spearman相关分析显示UAlb与HbA1c(r=0.248,P=0.000)、FPG(r=0.248,P=0.000)呈正相关;多元线性逐步回归分析显示,HbA1c及FPG水平仍然是UAlb的独立危险因素(P<0.05)。结论非糖尿病的Ⅰ、Ⅱ级原发性高血压患者中,HbA1c水平与UAlb呈独立相关,是评估高血压早期肾损害的重要指标。Objective To investigate the relationship between glycated hemoglobin A1c (HbA1c) and microalbuminuria in essential hypertensive patients.Methods 286 untreated patients with Ⅰ-Ⅱ grade essential hypertension from August 2011 to July 2012 in the First Affiliated Hospital of Fujian Medical University were enrolled,82 health participants in the same term were served as control group.According to level of HbA1c,all the hypertensive patients were divided into high HbA1c group (HbA1c≥6%,n =134) and normal HbA1c group (HbA1c < 6%,n =152).Urinary albumin (UAIb),urea nitrogen (BUN),creatinine (Cr),uric acid (UA) and glomerular filtration rate (GFR) were measured respectively for all the patients.The correlation and multivariate Logistic regression analysis were used to analyze the relationship between HbA1c and UAlb.Results There was no statistically significant difference in 3 groups in age,male ratio,body mass index,BUN,Cr,UA,triacylglycerol (TG),total cholesterol (TCHO),high-density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),fasting plasma glucose (FPG) (P > 0.05).Whereas,the level of UAlb in high HbA1c group was significantly higher than that of normal HbA1c group (15.0 mg/L vs 11.0 mg/L,P < 0.05).High blood pressure progression (5.0 years vs 5.0 years),SBP [(143.5±10.6) mm Hg vs (143.9±10.8) mm Hg],DBP [(83.9±8.7) mm Hg vs (83.2±8.4) mm Hg],Scr[(76.6±25.1) vs (70.8±19.9) μmol/L],BUN [(5.4±2.5) mmol/L vs(4.9±1.5) mmol/L],UA [(346.6±110.7) μmol/L vs (330.6±90.9) μmol/L)],GFR [(105.0±31.5) mL/min vs (105.8±31.3)mL/min)] between the two groups were found had no statistically significant difference (P > 0.05); UAlb,Scr,BUN,UA,GFR between normal HbA1c group and control group had no statistically significant difference (P > 0.05).FPG were found had positive correlation with HbA1c (r=0.248,P =0.000) and FPG (r =0.248,P =0.000)acc
