Abstract

This study was set out to determine the association of serum adiponectin and oxidative stress in newly diagnosed type 2 diabetes patients. 106 patients with newly diagnosed type 2 diabetes were recruited. Simultaneously scanning of the extracranial carotid arteries, common iliac arteries and femoral arteries were performed for measurement of intima media thickness (IMT) in all subjects. Atherosclerotic plaque was defined as IMT value >1.3 mm. The serum levels of adiponectin and 8-iso-prostaglandin F2α (8-iso-PGF2α), a marker of oxidative stress, were examined by enzyme-linked immunosorbent assay. Metabolic parameters were detected by clinical chemistry. According to the results, all of 106 patients with type 2 diabetes were newly diagnosed within 12 months, and aged 60.68±4.32 years. The level of serum adiponectin in newly diagnosed type 2 diabetes patients was lower than that in healthy subjects. Furthermore, type 2 diabetes patients with atherosclerotic plaques had lower serum adiponectin level than those without atherosclerotic plaques. Serum 8-iso-PGF2α level in newly diagnosed type 2 diabetes patients was higher than that in healthy subjects. Further analyses showed that serum adiponectin level was reversely associated with serum 8-iso-PGF2α in newly diagnosed type 2 diabetes patients. Additionally, the atherosclerotic plaques in newly diagnosed type 2 diabetes patients were positively correlated with total cholesterol, but negatively correlated with serum adiponectin level. Taken together, this study suggests that in newly diagnosed type 2 diabetes, serum adiponectin levels are probably associated with oxidative stress and also with the severity of atherosclerosis.

Keywords: 8-iso-PGF2α; Adiponectin; oxidative stress; type 2 diabetes.
