Aims To clarify the correlation between serum concentrations of soluble adhesion molecules and diabetic microangiopathy or macroangiopathy in patients with Type 2 diabetes. Methods Patients with diabetic retinopathy and intima‐media thickness of common carotid artery (CCA‐IMT) < 1.1 mm were classified as the microangiopathy group ( n = 62). Patients with CCA‐IMT ≥ 1.1 mm and without retinopathy were classified as the macroangiopathy group ( n = 95). Patients with CCA‐IMT < 0.9 mm and without retinopathy were assigned to the no complications group ( n = 139). Clinical characteristics and soluble intercellular adhesion molecule‐1 (ICAM‐1), vascular cell adhesion molecule‐1 (VCAM‐1), and E‐selectin levels were compared between the groups. Results Patients with microangiopathy had a significantly longer duration of diabetes, were hypertensive and more likely to have a positive family history of diabetes than the control group. Patients with macroangiopathy were more likely to be smokers, hypertensive, and have a family history of hypertension. Soluble ICAM‐1, VCAM‐1, and E‐selectin levels were significantly higher in the microangiopathy group than in the control group. Soluble VCAM‐1 and E‐selectin levels, but not ICAM‐1 levels, were significantly elevated in the macroangiopathy group. These results were unchanged after adjustment for age, sex, duration of diabetes, blood pressure, HbA 1c , HDL‐cholesterol, and smoking status. Conclusions Our results suggest that soluble adhesion molecules are related to both diabetic micro‐ and macroangiopathy. The relative contributions of adhesion molecules may be greater in the former than latter patients with Type 2 diabetes.
