• Biocompatibility in low-density lipoprotein apheresis and plasma separation 

      Hardersen, Randolf Inge (Doctoral thesis; Doktorgradsavhandling, 2021-02-12)
      <p><i>Introduction:</i> Low-density lipoprotein (LDL) apheresis is used for the removal of LDL in selected patients and is also used for other medical indications. This thesis aimed to systematically study how different LDL apheresis systems affected the immune system in a biocompatibility perspective under in vivo and ex vivo conditions. <p><i>Methods:</i> Whole blood adsorption, dextran sulfate ...

      <i>Introduction</i> - Even if proprotein convertase subtilisin/kexin type 9 inhibitors have replaced lipoprotein apheresis in many patients, lipoprotein apheresis still is an important option in homozygous familial hypercholesterolemia, progressive atherosclerosis or when removal of lipoprotein(a) is indicated. Additional possible favorable effects beyond lipid lowering could include changes in ...
    • Granulocyte and monocyte CD11b expression during plasma separation is dependent on complement factor 5 (C5) – an ex vivo study with blood from a C5-deficient individual

      The aim of the study was to investigate the role of complement factor 5 (C5) in reactions elicited by plasma separation using blood from a C5‐deficient (C5D) individual, comparing it to C5‐deficient blood reconstituted with C5 (C5DR) and blood from healthy donors. Blood was circulated through an <i>ex vivo</i> plasma separation model. Leukocyte CD11b expression and leukocyte–platelet conjugates were ...
