ReviewVascular endothelium as a target of beraprost sodium and fenofibrate for antiatherosclerotic therapy in type 2 diabetes mellitus.
Diabetes mellitus is an important risk factor for cardiovascular morbidity and mortality. The metabolic abnormalities caused by diabetes mellitus induce vascular endothelial dysfunction that predisposes patients with diabetes mellitus to atherosclerosis. Two mega clinical trials showed that intensive glycemic control does not have favorable effects on reducing macrovascular events although it demonstrated significant reductions in microvascular complications. ⋯ Beraprost sodium lowered circulating vascular cell adhesion molecule- 1 (VCAM-1) concentration and prevented the progression of carotid atherosclerosis in type 2 diabetic patients, probably through inhibiting VCAM-1 expression in vascular endothelium. Fenofibrate up-regulated endothelial nitric oxide synthase expression, which may explain its effects to improve endothelium-dependent vasodilatation and to prevent the progression of coronary atherosclerosis. The approaches to target the molecules expressed in vascular endothelium will become important for preventing the atherosclerosis in type 2 diabetes mellitus.
