Short-term efficacy and safety of pravastatin in 72 children with familial hypercholesterolemia.
The safety, tolerability, and efficacy of a 12-wk treatment with pravastatin, 5, 10, and 20 mg/d, was evaluated in 72 children with heterozygous familial hypercholesterolemia (FH) in a double-blind, randomized and placebo-controlled study. The results show that pravastatin was well tolerated and that adverse events were mild and equally distributed among the three treatment groups. Plasma total and LDL cholesterol levels were significantly reduced in all pravastatin treatment groups, in comparison with the control group; -24.6% (-28.1 to 21.0) and -32.9% (-37.0 to -28.6), for mean change and 95% confidence interval, respectively. In four children plasma LDL cholesterol levels were reduced within normal limits for sex and age. HDL cholesterol increased in the pravastatin 20-mg group, +10.8% (+3.4 to +18.8), whereas plasma apo B100 and very LDL (VLDL) cholesterol levels were reduced within all pravastatin-treated groups -26.8% (-31.2 [corrected] to -21.7) and -24.5% (-35.0 to -12.3). These data show that short-term pravastatin treatment of children with FH is safe and effective, although long-term dose titration studies with 3-hydroxy-3-methylglutaryl-CoA reductase inhibitors need to be performed, to reduce plasma LDL cholesterol levels below a predefined level. The results of these studies have to be awaited before new treatment strategies are to be considered in these children.
