History of lipidology and lipoprotein apheresis

This review tells the story of atherosclerosis research in the beginning of the 20th century. It presents the significance of cardiovascular diseases and addresses major questions currently being discussed among lipidologists and the current thinking with respect to low LDL-cholesterol levels and HDL. It provides an overview of the period during which lipid-modifying drugs were introduced and their relevance with respect to cardiovascular outcome data and lists possible reasons why some patients develop new cardiovascular events while being treated with statins. Especially impressive is the history of the appearance of the PCSK9 inhibitors on the market - only 12 years after PCSK9 was detected; a study completed in 2017 provides evidence about the cardiovascular effects of these new drugs. Other new drugs are also mentioned: mipomersen, lomitapide, and Alipogen Tiparvovec. Some promising drugs are still in the pipeline which inhibit the synthesis of apolipoprotein CIII, apolipoprotein(a), and the PCSK9 protein. During the 1970s, specific lipoprotein apheresis began to be used in high-risk patients with homozygous familial hypercholesterolemia, severe hypercholesterolemia and elevated Lipoprotein(a) levels and this review provides evidence of the effectiveness of the extracorporeal therapy with respect to the reduction of cardiovascular events. Particularly in patients with high Lipoprotein(a) levels, apheresis has been proven capable of reducing cardiovascular events by more than 80%. The current situation with regard to lipoprotein apheresis centers and patients in Germany is described herein, and, in conclusion, an estimation of the future of the therapeutic options in lipidology is given.
