ارتباط آدیپونکتین و نشانگر‌های آتروسکلروز پیش‌بالینی در مبتلایان جدید به دیابت نوع دو: بررسی ضخامت انتیما- میدیای شریان کاروتید و امتیاز کلسیم شریان کرونر

Background: The aim of this study was to assess the association of serum adiponectin and a set of traditional cardiovascular risk factors with carotid artery intimal-medial thickness (CIMT) and coronary artery calcium score (CACS), as markers of subclinical atherosclerosis in subjects with early type 2 diabetes mellitus. Methods: Carotid artery intima- media thickness (measured by B-mode ultrsonography), coronary artery calcium score (determined by high resolution computed tomography), serum adiponectin, Fasting blood sugar, serum lipids, body mass index (BMI), systolic blood pressure, diastolic blood pressure and mean arterial pressure were measured in 123 asymptomatic newly diagnosed cases of type 2 diabetes mellituss and 152 age and sex matched healthy control subjects. Results: Serum adiponectin and lipids were significantly lower in those with type 2 diabetes mellitus (P<0.01). Left, right and mean carotid artery intima- media thickness, coronary artery calcium score, fasting blood sugar, systolic blood pressure, diastolic blood pressure and mean arterial pressure were significantly higher among diabetic patients compared to healthy controls (P<0.05). Mean carotid artery intima- media thickness was positively and independently related to age (P<0.001) and triglyceride (P=0.01) in diabetic group. Coronary artery calcium score was associated positively with age (P=0.004) and inversely with high density lipoprotein (HDL) cholesterol (P=0.002) among diabetics. Conclusion: Although adiponectin was lower in diabetics compared to controls, it had no significant association with carotid artery intima- media thickness and coronary artery calcium score as markers of subclinical atherosclerosis. In patients with type 2 diabetes in addition to age, serum triglyceride levels are correlated with carotid artery intima- media thickness, while HDL cholesterol is inversely correlated with coronary artery calcium score.
