摘    要:目的了解早期糖尿病肾病(DN)患者体内凝血系统的变化。方法62例2型糖尿病患者根据尿白蛋白与肌酐比值(UACR)将患者分为以下两组:正常白蛋白尿(N—UAlb)组32例(UACR〈30mg/g)和微量白蛋白尿(M—UAlb)组30例(UACR30~300mg/g),并与30名正常对照(NC)组比较。用法国STAGO公司凝血分析仪检测血浆纤维蛋白原(FIB)、抗凝血酶(AT-Ⅲ)、蛋白c(PC)、蛋白S(PS),用ELISA法检测血管性血友病因子(vWF)和血小板颗粒膜蛋白140(GMP-140),用血细胞分析仪测定血小板计数(PLT)、血小板平均容积(MPV)、血小板压积(PCT)及血小板分布宽度(PDW)。结果M-UAlb组的FIB、GMP-140和vWF均高于N—UAlb组和NC组(4.20±1.53)、(3.21±0.89)、(2.75±0.53)g/L.(30.03±7.77)、(18.22±5.08)、(14.26±2.29)μg/L,(315.53±47.24)%、(191.88±57.25)%、(138.12±61.27)%,F值分别为5.42、10.42、30.44,P〈0.05或P〈0.01]。相关分析显示血浆FIB、vwF、GMPl40与UACR呈正相关(r=0.313,P〈0.05;r=0.620,P〈0.01;r=0.680,P〈0.01),PC与UACR呈负相关(r=-0.255,P〈0.05)。结论DN患者存在高凝状态,与FIB水平升高、内皮细胞损伤和血小板活化有关,而这些改变在正常白蛋白尿的糖尿病患者中已出现,因此临床工作中不仅要加强对DN患者的抗凝治疗,而且应在糖尿病患者未出现白蛋白尿时进行抗凝治疗。

Abstract:Objective To study the early changes of the coagulation system in type 2 diabetic nephropathy. Methods Sixty-two cases of patients with type 2 diabetic nephropathy were divided into two groups : normal albuminuria group ( N-UAlb group, UACR 〈 30 mg/g, 32 cases ) , microalbuminuria group ( M- UAlb group,UACR:30 - 300 mg/g,30 cases). Thirty healthy persons constituted a control group (NC group). Fibrinogen( FIB ), antithrombin Ⅲ ( AT- Ⅲ), protein C ( PC ), protein S ( PS ) were measured by coagulation analyzer,while von willebrand factor (vWF) and platelet granule membrane protein 140 (GMP-140) were detected by ELISA assay, platelet count ( PLT), mean platelet volume ( MPV ), platelet hematocrit (PCT) , platelet distribution width(PDW) by hematology analyzer. Results The level of fibrinogen, GMP-140 and vWF in the M-UAlb group were (4. 20 ± 1.53 )g/L, (30. 03 ± 7. 77 ) μg/L, and (315.53 ± 47. 24 )% respectively, vwhich were significantly higher than those in the N-UAlb group (3.21 ±0. 89)g/L, ( 18.22 ±5.08) μg/L and ( 191.88 ± 57.25 ) % respectively ] and the NC group ( 2.75 ± 0. 53 ) g/L, ( 14. 26 ± 2.29 ) μg/L and ( 138.12 ± 61.27) % respectively] ( F = 5.42,10.42,30.44, P 〈 0. 05 or 0. 01 ). The fibrinogen, vWF, GMP- 140 were positively correlated with UACR( r = 0. 313, P 〈 0. 05 ; r = 0. 620, P 〈 0. 01 ; r = 0. 680, P 〈 0.01 ) and PC was negatively correlated with UACR ( r = - 0. 255, P 〈 0.05 ). Conclusion Hypercoagulable state in diabetic nephropathy is associated with the high fibrinogen, endothelial dysfunction and platelet activation, and these changes have already emerged in patients without albuminuria. This might mind us that we should strengthen anticoagulant therapy on patients when they are not progressing to albuminuria.
