To evaluate the pharmacologic intervention most likely to decrease cardiovascular disease risk in insulin-resistant patients with combined dyslipidemia, 39 patients with this abnormality were assessed before and after 3 months of treatment with gemfibrozil (1,200 mg/day) or rosuvastatin (40 mg/day) with regard to: (1) steady-state plasma glucose concentration at the end of a 180-minute infusion of octreotide, insulin, and glucose; (2) fasting lipid, lipoprotein, and apolipoprotein concentrations; and (3) daylong glucose, insulin, triglyceride, and remnant lipoprotein cholesterol concentrations in response to breakfast and lunch. The 2 groups were similar at baseline in age, gender, body mass index and in measurements of carbohydrate and lipoprotein metabolism. Neither gemfibrozil nor rosuvastatin enhanced insulin sensitivity or lowered daylong glucose and insulin concentrations in insulin-resistant patients with combined dyslipidemia, but both drugs significantly decreased fasting triglyceride concentrations. However, only rosuvastatin treatment significantly (p <0.05 to <0.001) reduced fasting low-density lipoprotein cholesterol, apolipoprotein B-100, apolipoprotein C-III, apolipoprotein C-III:B particles, the apolipoprotein B-100:apolipoprotein A-I ratio, and increased apolipoprotein A-I (p <0.05). The degree of improvement in fasting and postprandial remnant lipoprotein cholesterol concentrations was significantly greater (p <0.05) in rosuvastatin-treated patients, and this difference in the relative effectiveness of the drugs was also true of the decrease in non-high-density lipoprotein cholesterol concentrations.
