Serum levels of lipids and lipoproteins were examined in individuals with hyperlipidemia treated with atorvastatin or colestimide and in healthy volunteers. Modified low-density lipoprotein (LDL) was measured by its faster electrophoretic mobility and expressed as charge modification frequency (CMF). Serum levels of total cholesterol (t-chol), triglyceride (TG), very low-density lipoprotein (VLDL)-chol, low-density lipoprotein (LDL)-chol, and CMF were significantly higher in hyperlipidemia, but there was no significant difference in serum high-density lipoprotein (HDL)-chol levels between hyperlipidemic and healthy subjects. Treatment with atorvastatin resulted in significant decreases of serum t-chol, TG, and LDL-chol levels but not serum HDL-chol and VLDL-chol. Treatment with colestimide significantly reduced serum t-chol, HDL-chol, and LDL-chol levels but not those of TG and VLDL-chol. CMF was significantly reduced by treatment with atorvastatin but not by colestimide. Atorvastatin significantly reduced plasma levels of thrombomodulin, thrombin antithrombin complex (TAT) and tissue type plasminogen activator-plasminogen activator inhibitor-I complex. Colestimide moderately prolonged activated partial thromboplastin time and reduction of TAT. Based on its actions of lowering modified LDL and improving hemostatic abnormalities, we postulate that atorvastatin might inhibit the onset of ischemic diseases.

Colestimide is a new anion-exchange resin used to lower serum cholesterol in Japan. Because of its excellent compliance, colestimide can replace cholestyramine. To clarify the effect of colestimide on glycemic controls, colestimide (3 g/day) or pravastatin (10 mg) was given orally to patients with type 2 diabetes treated with oral hypoglycemic agents or insulin who had low-density lipoprotein (LDL) cholesterol levels exceeding 3.6 mmol/l. In the colestimide groups, fasting plasma glucose concentrations had decreased significantly from 8.5 +/- 1.4 to 7.7 +/- 1.5 mmol/l at 3 months (P<0.05), as had glycated hemoglobin (HbA1c) from 7.7 +/- 0.7% to 6.8 +/- 0.5%, for an 8% reduction (P<0.01). Fasting plasma glucose and HbA1c did not change in the pravastatin group. Total cholesterol and LDL-cholesterol decreased significantly (P<0.01) with either medication, with similar reduction rates for both drugs. Doses of oral hypoglycemic agents and insulin did not change during the study, and body weight remained stable. Considering that patients with type 2 diabetes often have hyperlipidemia, colestimide therapy may have a clinically useful dual action in such patients.

The present study was undertaken to compare the efficacy of pitavastatin and colestimide in patients with diabetes mellitus complicated by hyperlipidemia and metabolic syndrome. 48 diabetic patients with metabolic syndrome were randomly assigned to a pitavastatin group or colestimide group. The clinical parameters, serum lipids, fasting (FPG) and postprandial plasma glucose(PPG), HOMA-IR, hemoglobin A1c(HbA1c), hs-CRP and urinary albumin were measured before/after 24-week administration. Treatment with pitavastatin reduced LDL-C and TG, while that with colestimide significantly reduced waist circumference, BMI, LDL-C, HbA1c, FPG, PPG, HOMA-R , hs-CRP and urinary albumin. Percent improvement in LDL-C was greater in the pitavastatin group than in the colestimide group. Colestimide appeared to be useful in the management of Japanese patients with diabetes mellitus complicated by metabolic syndrome, since it alleviates obesity and insulin resistance in addition to exhibiting lipid profile-improving effects, and can thus improve markers of atherosclerosis.

The objective of this study was to assess the chronic effects of a bile acid sequestrant, colestimide, on glucose metabolism. After db/db mice were fed a diet containing colestimide or cholic acid (CA) for 12 weeks, we investigated the impact of these agents on glucose and lipid metabolism. Colestimide significantly reduced the elevated fasting blood glucose level (p<0.01), and CA even more markedly reduced fasting blood glucose. The blood glucose level after an oral glucose load was significantly lower in the CA group than in the control group, but the colestimide group showed no significant difference. The insulin response to a glucose load was abolished in the control and colestimide groups. A hyperinsulinemic-euglycemic clamp study revealed that colestimide significantly improved the GIR (p=0.013). Hepatic EGP and Rd were also improved by colestimide, suggesting that it alleviated insulin resistance by suppressing hepatic glucose production and increasing peripheral glucose usage. CA significantly increased both the weight and cholesterol content of the liver, while colestimide reduced these parameters. Colestimide suppressed hepatic gene expression of SHP, but enhanced SREBP2 expression. On the other hand, CA increased the expression of SHP and lipogenic enzymes such as ACC and SCD-1, but had no effect on SREBP2. The present study demonstrated that colestimide improves hyperglycemia and hyperlipidemia, as well as reducing the hepatic lipid content. In contrast, CA exacerbates hyperlipidemia and increases the hepatic lipid content, although it improves glycemic control. Thus, colestimide is a well-balanced drug for the treatment of diabetes mellitus.
