چکیده

OBJECTIVE Dysregulated apolipoprotein (apo)C-III metabolism may account for hypertriglyceridemia and increased cardiovascular risk in the metabolic syndrome. This study investigated the dose-dependent effect of rosuvastatin on VLDL apoC-III transport in men with the metabolic syndrome. RESEARCH DESIGN AND METHODS Twelve men with the metabolic syndrome were studied in a randomized double-blind crossover trial of 5-week intervention periods with placebo, 10 mg rosuvastatin, or 40 mg rosuvastatin, with 2-week placebo washouts between each period. VLDL apoC-III kinetics were examined using a stable isotope method and compartmental modeling at the end of each intervention period. RESULTS Compared with placebo, there was a significant dose-dependent reduction with rosuvastatin in plasma triglyceride and VLDL apoC-III concentrations. Rosuvastatin significantly (P < 0.05) increased VLDL apoC-III fractional catabolic rate (FCR) and decreased its production rate, with a significant (P < 0.05) dose-related effect. With 40 mg rosuvastatin, changes in VLDL apoC-III concentration were inversely associated with changes in VLDL apoC-III FCR and positively associated with VLDL apoC-III production rate (P < 0.05). Changes in VLDL apoC-III concentration and production rate were positively correlated with changes in VLDL apoB concentration and production rate and inversely correlated with VLDL apoB FCR (P < 0.05). Similar associations were observed with 10 mg rosuvastatin but were either less or not statistically significant. CONCLUSIONS In this study, rosuvastatin decreased the production and increased the catabolism of VLDL apoC-III, a mechanism that accounted for the significant reduction in VLDL apoC-III and triglyceride concentrations. This has implications for the management of cardiometabolic risk in obese subjects with the metabolic syndrome.

Atorvastatin and fenofibrate have comparable effects on VLDL-apolipoprotein C-III kinetics in men with the metabolic syndrome.

OBJECTIVE The metabolic syndrome (MetS) is characterized by insulin resistance and dyslipidemia that may accelerate atherosclerosis. Disturbed apolipoprotein (apo) C-III metabolism may account for dyslipidemia in these subjects. Atorvastatin and fenofibrate decrease plasma apoC-III, but the underlying mechanisms are not fully understood. METHODS AND RESULTS The effects of atorvastatin (40 mg/...

Plasma apolipoprotein C-III transport in centrally obese men: associations with very low-density lipoprotein apolipoprotein B and high-density lipoprotein apolipoprotein A-I metabolism.

CONTEXT Apolipoprotein (apo) C-III is associated with hypertriglyceridemia and progression of cardiovascular disease. Plasma apoC-III is elevated in centrally obese men, and we hypothesized that the kinetics of apoC-III are disturbed in these subjects. OBJECTIVE We developed a compartmental model to determine very low-density lipoprotein (VLDL) and high-density lipoprotein (HDL) apoC-III meta...
