BACKGROUND: We elucidated the difference between the effects of bezafibrate and atorvastatin in hypertriglyceridemia with apoE2/2 and 3/3.
METHODS: An open randomized crossover study consisted of a 4-week treatment period with bezafibrate (400 mg daily) or atorvastatin (10 mg daily) and a 4-week wash-out period.
RESULTS: Bezafibrate significantly decreased serum concentrations of triglyceride (apoE2/2, E3/3: -49.2%, -39.0%) and significantly increased high-density lipoprotein (HDL) cholesterol (+28.5%, +26.1%) in both apoE phenotypes but did not change serum concentrations of low-density lipoprotein (LDL) cholesterol. Atorvastatin significantly decreased serum concentrations of LDL cholesterol (-34.0%, -30.0%) and triglyceride (-27.6%, -25.8%) in both apoE phenotypes but did not change HDL cholesterol concentrations. Changes in cholesterol in lipoprotein subfractions were not different between apoE2/2 and E3/3. Bezafibrate changed cholesterol distribution from small- to large-sized LDL and from large- to small-sized HDL. On the other hand, atorvastatin decreased cholesterol in all apoB-containing lipoprotein subfractions but did not change any of the HDL subfractions.
CONCLUSION: Bezafibrate and atorvastatin improve atherogenic dyslipidemia in considerably different ways. Extrapolating from the present data, we presume that the combination of these drugs may contribute to reduce LDL-C/HDL-C ratio effectively as well as lowering concentrations of serum triglyceride.
