To assess the contribution of the rs3846662 polymorphism of HMGCR on serum lipid levels and statin efficacy, we measured in vivo HMGCR mRNA and lipid levels in French Canadian individuals affected by heterozygous familial hypercholesterolemia due to the deletion of more than 15 kb of the LDLR gene.
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.
We evaluated the effects of different doses of lovastatin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG CoA reductase) and the rate-limiting enzyme in cholesterol biosynthesis, on parameters of cholesterol homeostasis in freshly isolated mononuclear leukocytes from 19 patients with heterozygous familial hypercholesterolemia.
Simvastatin (MK-733), a new inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A reductase, was administered to 38 patients with heterozygous familial hypercholesterolaemia for 24 weeks.
We have evaluated the hypolipidemic effects of mevinolin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase, the rate-limiting enzyme in cholesterol biosynthesis in 13 patients with heterozygous familial hypercholesterolemia (FH).
