RESUMO
The aim of our study was to investigate the role of intercellular mediators interleukin-1 receptor antagonist (IL-1 RA), interleukin-17 (IL-17), receptor activator of nuclear factor kB ligand (RANKL) and osteoprotegerin in the mechanisms of metabolic regulation of renal and bone tissue on model of violations of bone remodeling in chronic kidney disease (CKD). It was found a significant increase in the content of cytokines IL-1 RA (4,207 ± 0,546 pg/ml), IL-17 (33,944 ± 0,938 pg/ ml), osteoprotegerin (28,338 ± 1,223 pg/ml) and RANKL (0,184 ± 0,018 pmol/l) in the serum of animals in violation of bone remodeling in CKD compared with the contents of the studied cytokines in animals in the control group (2,529 ± 0,132 pg/ml, 28,166 ± 0,526 pg/ml, 21,588 ± 0,763 pg/ml and 0,131 ± 0,006 pmol/l, respectively) (P<0.05). The obtained correlations reflect the relationship between regulation of bone remodeling and the development of inflammation in CKD. The imbalance between pro- and anti-inflammatory cytokine plays an important role both in the development of CKD and in processes of bone remodeling.
