糖尿病肾病患者糖化血清蛋白测定的意义

Clinical significance of glycosylated serum protein in patients with diabetic nephropathy

目的探讨糖尿病肾病患者空腹血糖、糖化血红蛋白及糖化血清蛋白(GSP)等指标的关系。方法选取某医院确诊为糖尿病肾病患者303例,同时选取基线资料相似的糖尿病未并发糖尿病肾病患者167例作为对照,测定两组患者的空腹血糖、糖化血红蛋白及GSP,分析糖尿病肾病组三者之间的相关性,并与非糖尿病肾病肾病患者组相比较。结果糖尿病肾病患者血清空腹血糖、糖化血红蛋白及GSP含量显著大于非糖尿病肾病肾病患者(P<0.01),GSP与空腹血糖及糖化血红蛋白均呈正相关,相关系数(r)分别为0.606及0.733。结论糖尿病肾病患者血清GSP含量大于非糖尿病肾病肾病患者,糖尿病肾病患者GSP与血清空腹血糖及糖化血红蛋白三者关系密切。GSP测定简单、实用、稳定,可以弥补瞬时血糖监测的波动及糖化血红蛋白不能反映近期血糖平均水平的缺点。

Objective To explore the relations between fasting blood glucose （FBG）, glycosylated hemoglobin A1c （HbA1c） and glycosylated serum protein （GSP）. Methods FBG, HbA1c and GSP were measured in 303 patients with diabetic nephropathy and in 167 non-diabetic patients with comparable baseline data, and the correlations between FBG, HbA1c and GSP were analyzed. Results GSP levels were significantly higher in patients with diabetic nephropathy than in the non-diabetic patients （P〈0.01）. In patients with diabetic nephropathy, GSP levels were found to positively correlate to FBG （r=0.606） and HbA1c （r=0.733）. Conclusions Patients with diabetic nephropathy show strong correlations between FBG, HbA1c and GSP. GSP detection is convenient, stable, and practical in evaluating the average FBG over a short term, which reduces the interference by FBG fluctuations in conventional blood glucose monitoring
