Pleiotropic Effect of Lipoprotein-Apheresis on the Soluble Form of Activated Leukocyte Cell Adhesion Molecule (sALCAM) in Familial Hypercholesterolaemia

Introduction/Background Atherosclerosis is an inflammatory disorder in which several converging immune responses modulate and induce lipid accumulation in macrophages. Activated leukocyte cell adhesion molecule (ALCAM) has been described as a structural homologue of HDL-receptor and functions as a pattern recognition receptor (PRR), while its soluble form sALCAM is involved in ALCAM-dependent and -independent immune mechanisms. The aim of this study was to investigate the effect of aggressive removal of low density lipoprotein-cholesterol (LDL-C) and lipoprotein(a) (Lp [a]) by lipoprotein-apheresis (LA) on sALCAM and blood viscosity as well as to evaluate its association with lipoproteins and serum markers of inflammation.
