Effective reduction of plasma LDL levels by LDL apheresis in familial defective apolipoprotein B-100.
ATHEROSCLEROSIS(1992)
摘要
The clinical response to long-term reduction of the plasma LDL cholesterol concentration was studied in a man with severe coronary artery disease associated with familial defective apolipoprotein B-100 (FDB). Plasma exchange repeated at 2-week intervals, combined with lipid-lowering drugs, led to remission of angina and improved exercise test performance. A similar clinical response was achieved after LDL apheresis with dextran sulphate columns repeated once every 2 weeks in combination with drug treatment. The reduction in plasma LDL cholesterol level brought about by LDL apheresis was at least as marked in the FDB patient as in 5 patients with familial hypercholesterolaemia. We conclude that FDB patients with coronary artery disease may derive clinical benefit from prolonged reduction of their plasma cholesterol levels and that LDL containing apo B-100 in which arginine at position 3500 is replaced by glutamine is removed from plasma by dextran sulphate columns as efficiently as is normal LDL.
