摘要
目的 评价2型糖尿病患者血尿酸和尿白蛋白排泄率(UAER)之间的相关性。方法 将356例2型糖尿病患者依据UAER进行分组:UAER〈20μg/min为无白蛋白尿组(182例),UAER20-199μg/min为微量白蛋白尿组(120例),UAER≥200μg/min为大量白蛋白尿组(54例),并对血尿酸、UAER及相关临床资料进行分析。结果 无白蛋白尿组、微量白蛋白尿组、大量白蛋白尿组的平均血尿酸水平分别为(268±77)μmol/L、(298±90)μmol/L、(363±113)μmol/L(P〈0.05)。将血尿酸值从小到大排序,四分位后分别为(220±36)μmol/L(107-255μmol/L)、(287±24)μmol/L(256-315μmol/L)、(333±54)μmol/L(316-363μmol/L)、(416±65)μmol/L(364-613μmol/L),相应的白蛋白尿(包括微量白蛋白尿和大量白蛋白尿)的患病率分别为32.5%、46.2%、48.7%、59.2%(P〈0.01)。Pearson相关分析发现,UAER与血尿酸呈正相关(r=0.221,P〈0.05),另外还与体重指数、血甘油三酯呈正相关。调整年龄、性别、体重指数、高血压病史、胰岛素应用、吸烟、糖尿病病程、收缩压、舒张压、空腹血糖、血总胆固醇、血甘油三酯等因素后,血尿酸是白蛋白尿的独立危险因素(OR=1.56,P〈0.01)。结论 2型糖尿病患者血尿酸与UAER独立相关。
Objective To evaluate the relation between serum uric acid and urinary albumin excretion rate (UAER) in patients with type 2 diabetes mellitus. Methods A total of 356 patients with type 2 diabetes mellitus were recruited. Serum uric acid and UAER were determined. Normoalbuminuria group, microalbuminuria group and macroalbuminuria group were defined as UAER 〈 20 μg/min, 20 to 199 μg/min, and ≥1200 μg/min respectively. Results The respective uric acid levels for normoalbuminutia group, microalbuminuria group, and macroalbuminuria group were (268 ± 77) μmol/L, (298 ± 90) μmol/L, (363 ± 113)μmol/L (P 〈0.05). The mean values of serum uric acid for the first to the fourth quartile were (220 ± 36) μmol/L( 107 - 255 μmol/L), (287 ± 24) μmol/L (256 - 315 μmol/ L) ,(333 ±54) μmol/L(316-363 μmol/L),(416 ±65) μmol/L(364-613 μmol/L), respectively. Prevalence of abnormal albuminuria (microalbuminufia plus macroalbuminuria) for the respective quartiles were 32.5% ,46.2% ,48.7% ,59.2% ( P 〈 0.01 ). Serum uric acid correlated positively with UAER (r = 0. 221, P 〈 0.05 ), the odds ratio for abnormal albuminuria after adjusting for age, gender, body mass index, blood pressure, triglycerides, cholesterol and other confounders was 1.56 (P 〈0.01 ). Conclusion Serum uric acid is an independent correlate of UAER in patients with type 2 diabetes mellitus.
