Objective of this study was to determine the characteristics of the metabolic disorders of lipids and lipoproteins (LP) in the blood in 112 patients with systemic rheumatic diseases.Material and methods. In all patients, the level of C-reactive protein (CRP), the content of malonic aldehyde (MA) in circulating monocytes, in blood plasma, and catalase activity were determined. The presence and severity of pro-atherogenic status were evaluated by the content of modified low-density lipoproteins (LDL) and very-low-density lipoproteins (VLDL) in the blood, which was determined by the bioassay method using peritoneal mouse macrophages. The immunogenicity of modified LР was determined by the content in the circulating immune complexes (CIC) of cholesterol (Сhol) and triglycerides (TG). The spectrum of lipids and LP in the blood was evaluated in detail with an additional determination of the plasma level of proteins apoB and apoA-1 were determined.Results. The obtained results show the existence in the examined patients of significant systemic inflammation in conjunction with the distinct proatherogenic metabolic state that was revealed by lipoprotein modification with the appearance in them of auto-antigenic properties. These changes appeared despite the absence of significant traditional atherogenic risk factors. The results of the paired correlative analysis showed the existence of strong dependence between indexes of systemic inflammation, proatherogenic and immunogenic lipoprotein modification. Conclusions. When determining proatherogenic disorders of lipid and blood lipoproteins metabolism in patients with systemic rheumatic diseases, it is necessary to focus not on traditional risk factors, which may remain within normal values, but on the content of apoA-1, apoB proteins, their ratio, and the determination of modified lipoproteins blood and the severity of the autoimmune reaction to them.
