Input: Abstract: For the treatment of familial hypercholesterolemia, Liposorber LA-40 was clinically applied. The Liposorber is a commercially developed affinity adsorbent for plasma perfusion which selectivity adsorbs low density lipoproteins and very low density lipoproteins and is specially designed for plasmapheretic treatment of hypercholesterolemia. The Liposorber column, containing activated cellulose beads having an affinity for lipoprotein containing apolipoprotein-B, has an excellent adsorption capacity, excellent selectivity, minimum albumin loss. This new apheresis system was applied to 2 clinical cases. After seven months of trial perfusion every 2 weeks, patient condition was good, with a level of total cholesterol under 300 mg/dl. No replacement fluids were given during or after treatment. In this paper, clinical results of these patients were shown and the mechanism of adsorption of this specific adsorbent was discussed.
