摘    要:目的探讨2型糖尿病患者肾小球滤过率(GFR)的动态改变及相关临床因素的关系。方法1994~2008年进行过两次核素测定GFR的2型糖尿病住院患者309例,初次测定的GFR为基线值,根据末次测定GFR时的糖尿病病程分为3组;Ⅰ组:病程≤10年,76例,年龄(56.9±13.0)岁;Ⅱ组:病程〉10~20年,139例,年龄(65.1±9.1)岁;Ⅲ组:病程〉20年,94例,年龄(71.0±9.8)岁。各组之间末次GFR及同期测定的相关临床因素进行比较,计算GFR年下降率。结果随着年龄与糖尿病病程的增加,Ⅲ组的基线GFR、末次GFR均明显低于Ⅰ组、Ⅱ组,基线GFRI组、Ⅱ组、Ⅲ组分别为(73.5±26.8)ml/min、(71.6±22.0)rot/min、(63.0±21.3)ml/min;末次GFRI组、Ⅱ组、Ⅲ组分别为(67.5±27.7)ml/min、(61.6±24.8)ml/min、(47.O±23.4)ml/min(P〈O.01)。Ⅰ组、Ⅱ组、Ⅲ组的GFR年下降率分别为(3.6±10.4)ml/min,(2.7±7.8)ml/min,(4.6±7.4)ml/min(P〉0.05)。合并高血压的糖尿病患者较未合并高血压的糖尿病的基线GFR、末次GFR均明显降低,未合并高血压的糖尿病基线GFRI组、Ⅱ组、Ⅲ组分别为(87.9士18.5)ml/min、(80.2±19.1)ml/min、(79.3±19.0)ml/min;末次GFRI组、Ⅱ组、Ⅲ组分别为(85.0±22.5)ml/min、(75.0±18.7)ml/min、(68.6±17.0)ml/min。合并高血压的糖尿病基线GFRI组、Ⅱ组、Ⅲ组分别为(66.0±18.0)ml/min、(68.1±22.2)ml/min、(59.2±20.1)ml/min;末次GFRI组、Ⅱ组、Ⅲ组分别为(58.4±25.9)ml/min、(56.2±25.O)ml/min、(41.9±21.8)ml/min(P〈O.01)。结论年龄、病程是糖尿病肾病重要的独立危险因素,病程在20年以上的糖尿病患者GFR下降更为显著。合并高血压糖尿病患者的GFR以更快的速率下降。

Abstract:Objective To observe dynamic change and influencing factors of glomerular filtration rate(GFR) in type 2 diabetes. Methods 309 type 2 diabetic patients in 1994 -- 2008 were divided into three groups according to diabetes duration of last GFR: group Ⅰ (diabetes duration ≤10 years, n = 76) ; group Ⅱ (diabetes duration 〉 l0 - 20 years, n = 139);group Ⅲ (diabetes duration 〉20 years, n= 94). Last GFR and clinical characteristics were compared; baseline GFR,last GFR and the rate of GFR decline in type 2 diabetes with hypertension were compared,too. The rate of GFR decline was calculated. Results With age and diabetes duration increasing,baseline GFR and last GFR of group Ⅲ were more evidently decreased than those of group Ⅰ and group Ⅱ , baseline GFR: group Ⅰ was (73.5 ± 26.8) ml/ min,group Ⅱ was (71.6±22.0) ml/min,group Ⅲ was (63.0±21.3) ml/min,last GFR:group Ⅰ was (67.5±27.7) ml/min,group Ⅱ was (61.6±24.8) ml/min,group Ⅲ was (47.0±23.4) ml/min ( P 〈0.01) . The average yearly rate of GFR decline of group Ⅰ was (3.6±10.4) ml/min,group Ⅱ was (2.7±7.8) ml/min,group Ⅲ was (4.6± 7.4) ml/min ( P 〉0.05). Compared with baseline GFR and last GFR,type 2 diabetes patients with hypertension were more evidently decreased than type 2 diabetes ones without hypertension. In groups of type' 2 diabetes without hypertension,baseline GFR:group Ⅰ was (87.9±18.5) ml/min,group 11 was (80.2± 19.1) ml/min,group Ⅲ was (79.3±19.0) ml/min,last GFR:group Ⅰ was (85.0±22.5) ml/min,group Ⅱ was (75.0±18.7) ml/min,group Ⅲ was (68.6±17.0) ml/min. In groups of type 2 diabetes with hypertension,baseline GFR:group Ⅰ was (66.0±18.0) ml/min,group Ⅱ was (68. 1±22.2) ml/min,group Ⅲ was (59.2±20.1) ml/min, last GFR:group Ⅰ was (58.4±25.9) ml/min,group Ⅱ was (56.2±25.0) ml/min,group Ⅲ was (41.9±21.8) ml/min ( P 〈0.01),but the yearly rate of GFR decline
