Abstract
Preliminary experience of the efficacy and safety of a new regenerating system for selective extracorporeal removal of apolipoprotein B‐containing lipoproteins is described. Four patients with familial hyperlipoproteinaemia were studied on 10 occasions. A system of two, parallel, dextran sulphate cellulose columns was used, and plasma was processed continuously by passage through one of the columns while the other was being regenerated. With this procedure, reductions of very low density and low density lipoprotein cholesterol levels by 73 and 43%, respectively, could be achieved after treatment for 2.5–3 h (1000–3200 ml of plasma volume). No clinically relevant changes in the concentrations of other plasma proteins, including high density lipoproteins, were observed, and the treatment was well tolerated. We conclude that continuous selective apolipoprotein B apherisis is a safe and efficient lipid‐lowering procedure which may be used both for metabolic investigations and for studies on possible regression of atherosclerosis.
