PURPOSE OF REVIEW: Currently, different methods for extracorporeal elimination of atherogenic apolipoprotein B100 containing lipoprotein particles are used in clinical practice. Most of them effectively remove both lipoprotein(a) [Lp(a)] and LDL. The aim of this review is to highlight research describing the clinical advantages of specific Lp(a) immunosorption compared with other lipoprotein apheresis systems. RECENT FINDINGS: Data on the utility of lipoprotein apheresis in patients with elevated Lp(a) level are limited. However, several longitudinal studies demonstrated improvement in cardiovascular outcomes when both Lp(a) and LDL cholesterol levels were decreased with different apheresis systems. The main limitation of these trials is the absence of a control group. First developed in 1991, studies on apheresis with a specific immunosorbent to Lp(a) were small and noncontrolled before 2000s. The only prospective controlled clinical trial utilising Lp(a) apheresis (Clinicaltrials.gov NCT02133807), demonstrated regression of coronary and carotid atherosclerosis when Lp(a) was removed weekly for 18 months. SUMMARY: Lipoprotein apheresis usually affects multiple lipoproteins, and there are minimal data regarding the effect of specific removal of Lp(a) alone. There is a need for randomized controlled trial with specific Lp(a) apheresis to investigate its effect on cardiovascular outcomes.
