We evaluated in a double-blind, placebo-controlled, randomized trial of 45 well-defined patients with familial combined hyperlipidemia, the effect of gemfibrozil (1,200 mg/day) or simvastatin (20 mg/day) on apolipoprotein-B (apo-B)-containing lipoproteins, low-density lipoprotein (LDL) subfraction profile, and LDL oxidizability. Although both drugs reduced plasma cholesterol and triglyceride concentrations, gemfibrozil reduced plasma triglycerides more effectively and simvastatin reduced plasma cholesterol more effectively. LDL cholesterol was reduced with simvastatin. With both drugs, total serum apo-B concentration decreased. With gemfibrozil, this was due to an exclusive reduction (-46%) of very low/intermediate-density lipoprotein (VLDL + IDL) apo-B, whereas simvastatin decreased apo-B in both VLDL + IDL and LDL (34% and 15%, respectively). Initially, a dense LDL subfraction profile was present in all patients. The decrease in LDL cholesterol with simvastatin was due to a decrease in all isolated LDL subfractions except LDL2; gemfibrozil increased LDL1 and LDL2 cholesterol (p = 0.001) and reduced LDL4 cholesterol, resulting in a more buoyant LDL subfraction profile compared with simvastatin. In both groups, a predominance of small dense LDL remained despite therapy. LDL fatty acid composition showed a shift from oleic acid to linoleic acid after gemfibrozil; arachidonic acid increased after simvastatin. Vitamin E was lower after gemfibrozil. In the measurements of LDL oxidation, only the oxidation rate was significantly reduced with simvastatin. Thus, quantitative and qualitative changes of LDL cholesterol had only a small effect on total in vitro LDL oxidizability in this population with familial combined hyperlipidemia.
