The short-term effects of low-density lipoprotein (LDL) apheresis using a dextran sulfate cellulose (DSC) column equipped with a plasma separator using a polysulfone (PS) membrane filter on the serum total cholesterol, lipoprotein (a) (Lp (a)), C4b binding protein (C4bp), protein C and protein S and complement components levels were examined in a patient with familial hypercholesterolemia (heterozygote, type lla). PS/DSC-LDL apheresis markedly lowered the total cholesterol by 69.9 ± 2.9%, serum Lp (a) level by 80.2±3.4%, and C4bp by 81.1± 2.5% after 8 apheresis sessions. All the above parameters gradually returned to the baseline levels within 10 days. The free protein S level was not significantly changed, while the C4bp/protein S complex level was markedly decreased relative to the decrease in C4bp. The protein C level was moderately reduced by 29%. Almost all serum complements and complement co-factors as well as C4bp were moderately to markedly decreased after LDL apheresis, but returned to the initial levels within a few days. PS/DSC-LDL apheresis effectively eliminated both serum LDL and Lp (a), and did not have an adverse effect on fibrinolysis or complement cascade in the blood.
