摘要
目的 探讨2型糖尿病患者血清超灵敏C反应蛋白(hs-CRP)水平与机体胰岛素敏感性的关系。方法 运用高灵敏酶联免疫吸附法检测68例2型糖尿病患者和20名健康对照者的血清hs-CRP水平,同时检测血糖、血清胰岛素、糖基化血红蛋白(HbAlc)、尿白蛋白排泌率和血脂,并计算稳态模型胰岛素抵抗指数(HOMA-IR指数)和胰岛B细胞分泌指数(HOMA-IS)以分别反映机体的胰岛素敏感性和胰岛素分泌功能。结果2型糖尿病患者的血清hs-CRP水平显著高于对照(P<0.01),HOMA-IR指数和HOM-IS指数均低于正常对照(P<0.01)。进一步将患者按HbAlc分为血糖控制良好组(n=42)和血糖控制欠佳组(n=23)后发现,控制欠佳组的血清hs-CRP水平显著高于控制良好组(P<0.05)。线性相关分析显示,糖尿病患者的血清hs-CRP水平均与HbAlc、空腹血糖、体质量指数、舒张压和HOMA-IS指数呈显著正相关。结论 2型糖尿病患者血清hs-CRP水平高于正常人,而且与糖尿病的发生、发展有密切的关系。
Objective To investigate the relationship between serum level of highly sensitive C-reactive protein (hs-CRP) and insulin sensitivity in type 2 diabetic patients. Methods Serum hs-CRP level was determined by highly sensitive enzyme-linked immunosorbent assay (ELISA) in 65 patients with type 2 diabetes and 25 normal controls. Plasma glucose, serum insulin, glycosylated hemoglobin (HbA1c), urinary albumin excretion rate (UAER), plasma lipids and lipoprotein were also measured. Moreover, homeostasis model analysis (HOMA) of insulin resistance index (HOMA-IR) and islet secretion index (HOMA-IS) were calculated to estimate the insulin sensitivity and islet function. Results In the patients with type 2 diabetes, serum hs-CRP was increased, HOMA-IR index and HOMA-IS index were decreased as compared with the normal control subjects (P<0.01). Moreover, serum hs-CRP was significantly higher in poorly controlled diabetic patients (n=23) with HbA1c≥7% than that in well controlled diabetic patients (n=42) with HbA1c<7%. Liner regression analysis in diabetic patients showed that serum hs-CRP was negatively correlated with HOMA-IS index but positively correlated with fasting plasma glucose, body mass index, HbA1c and diastolic blood pressure, respectively. Conclusion Serum HS-CRP level is higher in the patients with type 2 diabetes than in normal subjects, and plays an role in the development and progression of type 2 diabetes mellitus.
