2型糖尿病肾病患者血清C肽水平变化的意义

目的 探讨2型糖尿病肾病患者血清C肽水平变化的意义.方法 选取住院2型糖尿病患者120例,按尿白蛋白排泄率大小分成3组,正常白蛋白尿组34例,微量白蛋白尿组40例,临床白蛋白尿组46例,同时设血糖正常健康组30例.测各组空腹血糖、糖化血红蛋白(HbA1c)、空腹血清C肽(FCP),并进行比较分析.结果 微量白蛋白尿组和临床白蛋白尿组患者血清C肽与正常健康组比较,差异有统计学意义(1.27±0.5)μg/L和(0.32±0.16)μg/L比(2.39±0.22)μg/L,P＜0.01];血清C肽水平与尿白蛋白排泄率呈负相关(r=-0.745,P＜0.01).结论 血清C肽水平的下降可能参与2型糖尿病肾病发生发展.

Abstract：

Objective To investigate the change of serum C-peptide level in type 2 diabetic nephrosis patients. Methods We recruited 120 patients with type 2 diabetes. The level of fasting plasma glucose (FBG), glycated hemoglobin (HbA1c), fasting C-peptide (FCP) and urinary albumin excretion rate (UAER) were measured.According to UAER, 120 patients were divided into Group Ⅰ: normal albuminuria group, 34 patients; Group Ⅱ:microalbuminuria group, 40 patients; Group Ⅲ: clinical albuminuria, 46 patients. At same time, we selected 30 healthy people as control group. Results The level of C-peptide decreased significantly in Group Ⅱ and Group Ⅲ compared with that of control group (P ＜0.01 ). The difference of C-peptide level between Group Ⅱ, Group Ⅳ and Group Ⅰ was statistically significant (P ＜ 0.01 ). The level of C-Peptide and urinary albumin excretion rate was negatively correlated (R = -0. 745 ,P ＜ 0. 01 ). Conclusion The decline of serum C-pcptide may be involved in the development of type 2 diabetic nephropathy.
