ABSTRACT
LDL apheresis is an extracorporal modality to lower the concentration of atherogenic lipoproteins, e.g., LDL cholesterol. We compared two recently introduced whole-blood LDL apheresis systems inpatients with hypercholesterolemia in a randomized cross-over trial with respect to their effects on lipoproteins as well as on other cardiovascular risk markers. Six patients (4 women, 2 men, median age 62.5 years, median BMI 25.9 kg/m(2)) on regular LDL apheresis were randomly assigned to receive six weekly treatments with either DALI (Fresenius) or Liposorber D (Kaneka). After 6 weeks, the patients were switched to the other device (again six weekly treatments). Blood was drawn before and immediately after LDL apheresis at three time points (last regular apheresis before the study; after six treatments with DALI and after six treatments with Liposorber D). LDL cholesterol concentration before the sixth apheresis (DALI 129 mg/dL, Liposorber D 132 mg/dL) as well as LDL cholesterol reduction during the sixth apheresis (DALI 68.3% and Liposorber D 68.4%) were similar with the two systems. CRP and fibrinogen concentrations were lower but interleukin-6, myeloperoxidase, and resistin concentrations were higher after the last Liposorber treatment compared with DALI (P < 0.05, respectively). No differences were observed concerning adiponectin, ghrelin, and PYY levels. In conclusion, both devices were highly effective in eliminating atherogenic lipoproteins. CRP and fibrinogen were better eliminated with Liposorber D. However, following Liposorber D, interleukin-6 levels were higher than after DALI possibly indicating an increased inflammatory activation.
