| Main Objective: To determine whether a four week treatment with vildagliptin compared to acarbose improves endothelial dysfunction in patients with type 2 diabetes mellitus.;Secondary Objective: •To determine the effect of vildagliptin on plasma levels of inflammatory markers and adipokines following a four week treatment with either vildagliptin or acarbose •To determine the effect of vildagliptin on fat cell morphology and gene expression following a four week treatment with either vildagliptin or acarbose • To determine the effect of vildagliptin on peripheral blood mononuclear cell responses to various stimuli following a four week treatment with vildagliptin compared to acarbose ;Primary end point(s): Forearm vasodilatory response to increasing doses of intra-arterially administered acetylcholine (endothelium-dependent) and sodium nitroprusside (endothelium-independent) following 4 week treatment with vildagliptin and acarbose | — |
