Abstract\ud Several pieces of evidence support a role of inflammatory processes in the pathogenesis of atherosclerosis; it is also known that endothelial dysfunction is the initial lesion of the atherosclerotic process. Among other markers of endothelial dysfunction, some adhesion molecules seem to play an interesting role. The aim of the present study was to evaluate the effect of atorvastatin vs placebo on some indexes of leukocytes adhesion in a group of Type 2 diabetic patients. Twenty-five Type 2 diabetic patients free from microangiopathic complications and with LDL-cholesterol lower than 180 mg/dl were randomized to receive either atorvastatin (T2DA) or placebo (T2Dp) for twelve months. BMI, fasting plasma glucose, glycated hemoglobin (HbA1c), albumin excretion rate (AER), lipid profile, and serum concentrations of vascular cell adhesion molecule-1 (VCAM1), E-selectin and cadherin-5 were measured at baseline and at the end of the follow-up. At T0 E-selectin was 16 +/- 6 ng/ml in T2DA and 17 +/- 13 in T2Dp; VCAM1 was 413 +/- 112 ng/ml in T2DA and 411 +/- 112 in T2Dp. At T12 VCAM1 and E-selectin did not vary in T2Dp, while a significant reduction was observed in T2DA (VCAM1 275 +/- 104 ng/ml and E-selectin 8 +/- 3 ng/ml; p < 0.001 and p < 0.01, respectively). T2DA also showed a reduction of total and LDL cholesterol and an improved glycemic control respect to T2Dp. Hypolipidemic therapy was the strongest independent predictor of the cytokines variations along the time. These results confirm the role of statins in modulating endothelial function also in Type 2 diabetes, outlining a therapeutic role of these molecules probably independent from the hypolipidemic effect
