    Abstract:
    Direct adsorption of lipoproteins (DALI) apheresis has been shown to reduce effectively low-density lipoprotein (LDL) cholesterol and lipoprotein (a) concentrations. However, the effects on nontraditional risk indicators such as hemorheology and LDL subtypes have not been investigated so far. Five patients (2 women, 3 men, age 53 +/- 8 years) with coronary artery disease and severe LDL hypercholesterolemia regularly treated with other LDL apheresis devices entered the study and were then treated with DALI for the first time. Hemorheological and lipoprotein parameters were measured before and immediately after the initial DALI apheresis as well as before the fourth DALI apheresis. Compared to baseline (before the first DALI apheresis), the following parameters were significantly improved (p < 0.05) after the first DALI apheresis: LDL cholesterol (69 +/- 28 versus 208 +/- 82 mg/dl) and cholesterol in each LDL subfraction as well as plasma viscosity (1.23 +/- 0.04 versus 1.37 +/- 0.06 mPa), C-reactive protein, native blood viscosity, red cell aggregation, and red cell deformability. When parameters before the fourth DALI apheresis were compared to baseline, LDL cholesterol was still lower, and red cell deformability was still improved while cholesterol in each subfraction showed a statistical trend to lower concentrations (0.08 < p < 0.14). In conclusion, DALI apheresis not only reduces LDL cholesterol but also induced a significant reduction of cholesterol in all LDL subfractions and improved various hemorheological parameters.
