Alirocumab in lipoprotein apheresis: A synergy for patients with high-Lp(a).

Until today lipoprotein apheresis (LA) is considered the most effective treatment for patients with high-Lp(a) and proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are often combined with LA to dampen the rebound in lipoprotein concentrations. The aim of the present work is to evaluate the effect of dose-adjustment strategy for alirocumab in a small cohort of high-Lp(a) subjects with ischemic heart disease and in chronic LA treatment. Chronic LA effect on Lp(a) levels is a significant reduction in pre-LA Lp(a) concentrations compared to native Lp(a) value (118 [116-119] mg/dl vs 150 [137-155] mg/dl; p < 0.001). Furthermore, the administration of Arilocumab 75 mg after 7 days from LA shows a significant pre-LA reduction in the Lp(a) concentrations respect to those obtained with administration immediately after the LA treatment. In high-Lp(a) patients treated with chronic LA the deferred addition of alirocumab, resulted in lower LDL-cholesterol and Lp(a) values.
