Abstract

Combination therapy of rosiglitazone and atorvastatin has been shown to have beneficial effects on glycemic control and lipid profiles in patients with type 2 diabetes mellitus. This study investigated the effects of the combination of rosiglitazone and atorvastatin on vascular inflammation by studying their effects on levels of biomarkers in patients with type 2 diabetes mellitus. Thirty patients with type 2 diabetes mellitus and hyperlipidemia were enrolled to receive rosiglitazone monotherapy at 4 mg/day for 3 months and then atorvastatin at 10 mg/day was added for 3 more months as combined therapy. Inflammatory biomarkers, including high-sensitivity C-reactive protein (hs-CRP), matrix metalloproteinase-9 (MMP-9), soluble CD40 ligand (sCD40L), and adiponectin, and lipid profiles were measured at the time of initiation, after rosiglitazone monotherapy and after combination therapy with rosiglitazone and atorvastatin. With treatment of rosiglitazone at 4 mg/day monotherapy for 3 months, hs-CRP levels decreased significantly by 26% (p <0.05) and adiponectin levels increased significantly by 192% (p <0.05), but no significant changes in levels of MMP-9 and sCD40L were demonstrated. After combination therapy, hs-CRP levels further significantly decreased by another 23% (p <0.05) and adiponectin further increased by another 124%. In addition, serum levels of MMP-9, sCD40L, total cholesterol, and low-density lipoprotein cholesterol decreased significantly compared with baseline levels. In conclusion, combination therapy with rosiglitazone and atorvastatin not only significantly improved lipid profiles but also decreased levels of vascular biomarkers, such as hs-CRP, MMP-9, and sCD40L, and increased serum adiponectin levels in patients with type 2 diabetes mellitus.
