Abstract
BACKGROUND
Hypoadiponectinemia and hyperresistinemia are associated with cardiovascular disease. The increase in the carotid intima-media thickness (CIMT) assessed by B-mode ultrasound has been directly associated with increased risk of myocardial infarction and stroke.
OBJECTIVE
To evaluate the correlation between adipokine levels with CIMT in hypertensive type 2 diabetic patients.
METHODS
Serum levels of adiponectin and resistin levels were measured by ELISA in 30 type 2 diabetic patients with never-treated hypertension and in age-matched healthy controls. The CIMT (B-mode color imaging of extracranial carotid arteries using high-resolution ultrasound) was also obtained. The relationship between adipokine levels and the adiponectin/resistin index with the CIMT was assessed by the Pearson correlation coefficient test.
RESULTS
Adiponectin was lower (p < 0.05), and resistin higher (p < 0.01) in patients than in controls, CIMT correlated positively with resistin (R = 0.45, p < 0.02) and the adiponectin/resistin index (R = 0.58, p < 0.001), but not with adiponectin levels (r = -0.11, p > 0.1) in patients. Whereas only adiponectin levels correlated - negatively - with CIMT (r = -0.39, p < 0.02) in controls.
CONCLUSION
Our results shown that the adiponectin/resistin index seems to be more strongly associated with atherosclerosis than adipokine levels, and may be used as a reliable marker of cardiovascular risk in type 2 diabetic hypertensive patients.
