Association between serum amyloid A and carotid intima-media thickness in patients with type 2 diabetes / 中国医师杂志

ABSTRACT

Objective To explore the association between serum amyloid A (SAA) and carotid intima-media thickness (CIMT) in patients with type 2 diabetes mellitus(T2DM).Methods A total of 148 diabetic subjects were divided into three groups according to C1MT:normal IMT group,IMT incrassation group and arteriosclerosis group.Levels of SAA,25-hydroxyvitamin D [25 (OH) D],brachial-ankle artery pulse wave velocity (baPWV),high density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),fasting plasma glucose (FPG),glycosylated hemoglobin (HbA1 c),triglyceride (TG),total cholesterol (TC),body mass index (BMI) and blood presure were measured in all groups.The relationship between SAA,CIMT,25 (OH)D,baPWV and other factors was also analyzed.Results Compared to the normal IMT group,levels of FPG,HbA1 c,TC,BMI,SAA and ba-PWV were significantly higher in IMT incrassation group and arteriosclerosis group,while HDL-C and 25 (OH)D were lower.In arteriosclerosis group,levels of BMI,FPG,HbA1 c,SAA and ba-PWV were higher than those in IMT incrassation group,while 25 (OH) D was lower.Pearson correlation analysis showed that the level of SAA was positively correlated with baPWV,BMI,TC,course of disease and IMT,while it was negatively correlated with HDL-C and 25 (OH)D.Logistic regression analysis of IMT showed that smoking,obesity,high levels of HbAlc,FPG,TC,SAA,low levels of HDL-C and 25 (OH)D may contribute to higher levels of IMT.Conclusions SAA was closely related to carotid atherosclerosis.Further prospective studies will be helpful to explore the influence of SAA on diabetic macroangiopathy.
