Sitosterol in juvenile type II hyperlipoproteinemia

The effect of beta-sitosterol on plasma lipids and lipoproteins was evaluated in a randomized double-blind cross-over trial in 15 children and adolescents with familial hypercholesterolemia over a period of 6 months. Twelve patients completed the study, with good adherence to drug intake. Sitosterol lowered the plasma total choelsterol by 6%, LDL cholesterol by 7% and HDL cholesterol by 15% (P less than 0.05). This insufficient response of total and LDL cholesterol and the marked fall of HDL cholesterol appears to advise against the use of beta-sitosterol granulate in juvenile type II hyperlipoproteinemia.
