title: Changes in coagulation factors by passage through a dextran sulfate cellulose column during low-density lipoprotein apheresis.
abstract: To determine the extent of adsorption of coagulation factors by a dextran sulfate cellulose column used for selective removal of low-density lipoprotein (LDL), various coagulation factors were measured before and after application to the column during LDL apheresis. The column almost completely adsorbed many coagulation factors. Although the bradykinin concentration was markedly increased by passing the plasma through the column, this increment was suppressed by nafamostat mesilate which inhibits the initial contact phase of the intrinsic coagulation pathway. The von Willebrand factor, which forms a complex with factor VIII in plasma, is reduced in apheresis with nafamostat mesilate to the same extent as in apheresis without nafamostat mesilate. Thus, coagulation factors seem to be adsorbed by different mechanisms which include activation of the initial contact phase by the negative charges of dextran sulfate and concomitant adsorption with the phospholipid portion of lipoproteins containing apolipoprotein B or with von Willebrand factor.
