Lipoprotein dysfunction in patients with chronic kidney disease (CKD). Pathogenesis and treatment of CKD dyslipidemia (literature review)

Abstract

Dyslipidemia develops in the initial stages of chronic kidney disease (CKD) and worsens as nephropathy progresses. The main manifestation of dyslipidemia is hypercholesterolemia, especially in nephrotic syndrome. However, with CKD of stages 4-5, it is replaced by hypertriglyceridemia in combination with an increase in blood levels of lipoproteins low and very low density. Such changes are closely related to the development of cardiovascular pathology with high mortality. The content of high-density lipoproteins (HDL) in the blood is gradually decreasing, as well as the reversible transport of cholesterol. Thus, their anti-atherogenic, antioxidant and anti-inflammatory functions are lost. The main components of HDL – apolipoproteins ApoA-I and ApoA-II, which provide functionality, are replaced by acute-phase proteins, and HDL lose their cardioprotective potential and acquire a proinflammatory and proatherogenic phenotype. According to modern concepts, HDL dysfunction, along with metabolic shifts, is largely due to epigenetic disorders affecting gene expression and partially eliminated by prescribing drugs containing microRNAs (mRNAs) or antisense nucleotides. Drugs with interfering RNAs created in recent years have been successfully used not only for the treatment of dyslipidemia in nephrological patients, but also in patients with neoplastic processes, inflammatory arthritis, degenerative diseases of the central nervous system, porphyria, hemophilia and many other diseases. The proposed review is devoted to the mechanisms of disorders of the structure and functions of HDL in patients with CKD and the correction of these disorders.
