CORRELATION BETWEEN THE LIPID PROFILE AND THE IMMUNOLOGICAL CHARACTERISTICS IN THE ELDERLY

Georgian Med News. 2015 Jun:(243):52-8.

Abstract

Some changes in lipid metabolism and immune status occurring at aging are accompanied with development of inflammatory metabolic disorders and age-associated pathologies. It is well-known that permanent stimulation of immune responses may lead to hyperlipidemia that, in its turn, may evoke immune disturbances and affect the auto-inflammation processes. It seems important to explore a mutual relationship between lipid metabolites and immunology markers in order to better manage the age-associated diseases. In Georgian population the study on associations between the lipid metabolism and the immunological parameters might be especially interesting due the specific geo-climate environment and dietary peculiarities of the country. Study involved 250 healthy volunteers at the age of 18-80 years that were tested on the lymphocyte sub-populations (CD3+CD4+, CD3+CD8+, CD4+CD8+, CD4+CD25+FoxP3+) in peripheral blood, as well as on the levels of lipids (Low-and High density lipoproteins, triglycerides and total cholesterol levels. The study revealed statistically significant differences between the under-60 and above-60 age groups by the level of lipids (low density lipoproteins and total cholesterol) and of CD4+CD25+FoxP3+ cell counts in the healthy population of Georgia. Meanwhile, the lipid fractions (low density lipoproteins, triglycerides and total cholesterol) showed statistically reliable positive correlation with CD4+CD8+ cell but negative correlation with CD4+CD25+FoxP3+cell counts.
