成人隐匿性自身免疫糖尿病与2型糖尿病动脉内中膜厚度的研究

目的探讨成人隐匿性自身免疫糖尿病(LADA)与2型糖尿病(T2DM)患者亚临床动脉粥样硬化(AS)的差异及其影响因素。方法选取2002年8月至2005年2月中南大学湘雅二医院70例LADA患者,检测其颈总动脉及股动脉内中膜厚度(IMT),与匹配的T2DM患者进行比较。采用多元线性回归分析LADA患者IMT增加的危险因素。结果LADA和T2DM患者亚临床AS发生率相似(11.4%对17.1%,P>0.05)。多元线性回归分析显示,年龄、胰岛素抵抗指数(HOMA-IR)、吸烟及低密度脂蛋白胆固醇(LDL-C)是颈总动脉IMT增加的主要影响因素;年龄、HOMA-IR、性别及LDL-C是股动脉IMT增加的主要影响因素。结论该组LADA与T2DM患者亚临床AS发生率相似。LDL-C、吸烟、性别、年龄及HOMA-IR可能是LADA患者IMT增加的主要影响因素。

The comparison of artery intima-medial thickness between latent autoimmune diabetes in adults and type 2 diabetes

Objective To explore and compare the prevalence of subclinical atherosclerosis between LADA and type 2 diabetes,and investigate the risk factors of artery intima-medial thickness (IMT) in LADA patients.Methods The CCA-IMT and FA-IMT were observed in 70 LADA (GADA positive) patients and 70 T2DM ( GADA negative) subjects matched with age,gender and duration. Risk factors of IMT were estimated with multiple linear regression analysis.Results The prevalence of subclinical atherosclerosis between LADA cases and type 2 diabetic patients was similar (11.4% VS.17.1%,P>0.05).In LADA patients,multipe linear regression analysis showed that the risk factors related to the intima media thickness of common carotid artery were age,smoking and LDL-C and the risk factors related to the intima medial thickness of femoral artery were age,sex and LDL-C.Conclusion The prevalence of subclinical atherosclerosis between LADA and type 2 diabetes is similar.LDL-C,age,sex and smoking may be the risk factors of subclinical AS in LADA patients.
