Role of lipid-lowering pharmacotherapy in children.
For patients with coronary artery disease and healthy middle-aged or older individuals with elevated cholesterol levels, treatment with cholesterol-lowering drugs reduces morbidity and sometimes mortality. Treatment reverses established atherosclerotic lesions within a relatively short period of time, suggesting that starting cholesterol-lowering drugs in adulthood is adequate for most people at risk. Children with genetic lipid disorders, including familial hypercholesterolaemia and familial combined hyperlipidaemia, may be candidates for earlier therapy. A complete assessment of risk factors should be undertaken to determine which children are at highest risk. Treatment should start with diet, because diet is an important independent protective factor for disease. The bile acid sequestrants (resins) are the only drugs approved for children and may reduce low density lipoprotein (LDL)-cholesterol levels by 15 to 20% at best. Long term tolerability is good, but many children will not take the resins because they find them unpalatable. Tablet formulations have higher acceptability. Some children require supplementation with fat soluble vitamins or folate. Although hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors have not been tested in long term studies in children, safety records are excellent in adults. Short term studies show that HMG-CoA reductase inhibitors reduce LDL-cholesterol levels similarly in children and in adults. Thus, the drugs may be used in low dosages to treat some adolescents with exceptional risk of disease.
