Relationships Between Lipid Profile and Complete Blood Cell Count Parameters

Abstract

Aim. Given that blood cells play an important role in both atherogenesis and lipid metabolism, the research aimed to assess the specifics of the relationship between the parameters of the blood lipid spectrum and the complete blood count (CBC).
 Materials and Methods. A total of 475 individuals (245 female and 230 male) were included in the study, who simultaneously underwent CBC and determination of lipid profile, namely: total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG). Statistical processing of the obtained data was carried out using the "Statistica for Windows 6.0" software package (Statsoft, USA).
 Results. An increase in levels of TC and LDL-C was associated with an increase in the count of lymphocytes and erythrocytes. A rise in VLDL-C and, accordingly, TG levels, as well as a decrease in the level of HDL-C, were associated with an increase in the total leukocyte count in the blood without a significant change in the ratio of their different types, and an increase in erythrocyte sedimentation rate. The count of platelets was directly related to the level of LDL-C and increased in the case of a combination of elevated levels of LDL-C and TG.
 Discussion. The obtained results indicate that the disposal of excess lipoproteins is based on various types of immune reactions. An increase in the levels of VLDL-C and TG is associated with the development of a nonspecific leukocyte reaction, and an increase in LDL-C levels is associated with a more specific platelet-lymphocytic response. A simultaneous increase in LDL-C and TG levels can be associated with the development of both specific and non-specific immune reactions. An increase in the level of HDL-C leads to a decrease in the intensity of innate and adaptive immune responses. Therefore, the lipid profile of patients should be evaluated by taking into account the blood cell counts, especially in the process of hypolipidemic treatment.
 Conclusions. An atherogenic lipid profile is associated with increased counts of all blood cells, reflecting specific and nonspecific immune reactions in response to elevated levels of various lipid groups. Platelets play an important role in lipid metabolism.
 Connection of the research with scientific programs, plans, and topics.

Association of Atherogenic Index of Plasma with Cardiometabolic Risk Factors and Markers in Lean 14-to-20-Year-Old Individuals: A Cross-Sectional Study

“…Erythrocyte counts increased significantly (within their reference range) across the AIP quartiles only in males and were selected as significant predictors of AIP even in males on low risk. Ukrainian authors reported a significant direct relationship between erythrocyte counts and triacylglycerols in healthy adults, while the association with HDL-C was insignificant [40]. However, they did not investigate the associations of erythrocyte counts with atherogenic indices.…”
