Long term-effect of fenofibrate on lipoprotein level and composition in different types of genetic hyperlipidemias

Fenofibrate effect on plasma lipids and lipoproteins was studied in 23 patients with primary hyperlipoproteinemias (HLP): 12 with familial hypercholesterolemia (FH), 5 with combined HLP and 6 with Type III HLP. Trial lasted from 8 to 10 months. Cholesterol and triglycerides were significantly reduced in all patients as follows: cholesterol dropped 26% in FH (p less than 0.001), 32% in combined HLP and 48% in type III HLP; triglycerides dropped 29%, 64% and 72% respectively. This drop involved LDL in FH, VLDL and LDL in combined HLP and beta-VLDL in type III HLP patients. In FH and combined HLP patients we observed a +10% (p less than 0.01) and a +9% (n.s.) increase of HDL, respectively. Two patients had a mild SGOT and SGPT increase and three had a vescicular cutaneous erythema.
