ABSTRACT
The aim of this study was to determine whether a relatively low dose of pioglitazone or metformin was effective in diabetic patients with metabolic syndrome. Fifty diabetic patients with metabolic syndrome were randomly assigned to a low-dose pioglitazone (15 mg/day) treatment group or a low-dose metformin (500 mg/day) treatment group. Drugs were administered for 12 weeks. Systolic and diastolic blood pressure, heart rate, body mass index, triglyceride (TG), HDL and LDL-cholesterol, fasting plasma glucose (FPG), fasting plasma insulin (IRI), postprandial glucose, and HOMA-IR in the 75gOGTT, HbA1c, high-sensitivity CRP (hs-CRP) determined by cervical artery echography, and pulse wave velocity (PWV) were measured before/after 12-week drug administration. Significant decreases in HbA1c and HOMA-IR were noted in the pioglitazone group, along with significant decreases in TG, AST, ALT, blood pressure, hs-CRP and PWV. Significant decreases in HbA1c, HOMA-IR, BMI and waist circumference were noted in the metformin group. The pioglitazone group significantly improved the values for ALT, systolic blood pressure, hs-CRP and PWV compared to the metformin group. However, the metformin group demonstrated significant improvement in BMI compared with the pioglitazone group. Using a low dose regimen, pioglitazone significantly improved blood pressure and hepatic function and may be more effective than metformin to reduce risk factors in Japanese diabetic patients with metabolic syndrome at preventing atherosclerosis.
