PCSK9-inhibitors belong to the new class of hypolipidemic agents. They enhance catabolism of low density lipoprotein cholesterol (LDL-C) through inhibiting activity of proprotein convertase subtilisin/kexin type 9 (PCSK9). They are monoclonal antibodies (alirocumab, evolocumab etc). Under clinical development are also other types of PCSK9-inhibitors which act at a subcellular level. The treatment with PCSK9-inhibitors can be beneficially combined with lipoprotein apheresis (LA). If such treatment using PCSK9-inhibitors is possible with regard to an individual patients genotype, the combination of LA and PCSK9-inhibitors leads to slowing the space of LDL-C increase between individual procedures of apheresis and enables attaining of the lowest possible values of LDL-cholesterolemia for the longest possible period of time. Due to high efficiency of PCSK9-inhibitors lowering LDL-C, but also their lower cost as compared to therapeutic LA, PCSK9-inhibitors now take precedence over the use of extracorporeal lipoprotein apheresis which, nonetheless, still remains the final method for hypolipidemic treatment of patients with severe hypercholesterolemia, who are resistant to conventional therapy while not reaching the target lipid values and at high cardiovascular risk. They belong to extracorporeal elimination methodologies which remove low density lipoprotein (LDL) cholesterol from circulating blood. LA in combination with higher doses of statins and ezetimib currently represents the most efficient method of treatment of homozygous and statin-refractory heterozygous familial hypercholesterolemia (FH). Residual cardiovascular risk in these patients still remains high, in particular because, despite the aforementioned treatment, the target values for lipids according to present recommendations cannot be reached. The combination of LA with the new drugs is promising, primarily due to its potential for further lowering of LDL-cholesterolemia between the individual apheresis procedures. Preliminary results of the ongoing studies indicate that the new hypolipidemic drugs in combination with LA, or when used separately, will substantially enrich and improve the treatment of refractory FH.Key words: alirocumab - atherosclerosis - evolocumab - hypercholesterolemia - cardiovascular disease - lipoprotein apheresis.

Lipid-lowering treatment is a part of prevention and treatment of vascular diseases caused by atherosclerosis. We need new strategies for modifying plasma lipoprotein levels in the light of new findings that reduce target lipid levels further lower, as well as the growing population of patients for whom existing treatments cannot be offered. The spectrum of existing drugs (new statins) is widening, pharmacological treatments (recombinant lipoproteins-bound statins), improved forms of established drugs (selective PPARα receptor modulators) are coming. The new procedures include fixed combinations of established drugs improving adherence and intensifying lipid modifying effects (statin + ezetimibe). The portfolio of lipid-lowering therapies today also includes monoclonal antibodies against PCSK9 (PCSK9 inhibitors). The main direction of future development is biotechnology using the principle of so-called antisense therapy, i.e. the use of specific oligonucleotide sequences blocking the translation of the selected protein. These novel therapies targeting, for example, apolipoprotein B, apolipoprotein CIII, or lipoprotein(a) are in various stages of clinical trials. A simi-lar (but not identical) principle is the use of RNA silencing - interference with gene expression using short sequences of double-stranded RNA (e.g. inclisiran siRNA against PCSK9). Innovations in the field of hypolipidemic pharmacotherapy in our country may also be inhibitors of microsomal triglyceride transfer protein (approved for use in homozygotes for familial hypercholesterolemia and experimentally also for familial chylomicronemia). The small molecule ATP citrate lyase inhibitor, bempedoic acid, decreases LDL-C by a further 20 % over and above the reduction achievable by a statin. In a broader sense, the novelty of hypolipidemic pharmacotherapy includes treatment options for some rare metabolic diseases (eg. enzyme replacement therapy for acid lysosomal lipase deficiency) manifested by lipoprotein metabolism abnormalities. All these new directions must aim at the common main goal of reducing the incidence of cardiovascular and gastrointestinal complications of dyslipidemia. Clinical research also aims to prove these effects.
