Aim: comparative assessment of the state of joint (hyaline) cartilage, pro-inflammatory component of cytokine profile and enzyme element of blood antioxidant system in healthy individuals and patients at the early stages of gonarthrosis. Materials and Methods. The content of cartilage oligomeric matrixprotein (COMP), superoxide dismutase-2 (mitochondrial) (SOD-2) and interleukin-1 (3 (IL-1 (3) was studied in 34 individuals with initial signs of gonarthrosis (main group) and in 20 conventionally healthy individuals (control group) in blood serum by ELISA. Results. In the serum of patients with GA, the content of COMP (Me=20.67 pg/ml; 25% quartile 14.70; 75% quartile 27.15) and IL-1(3 (Me=4.74 pg/ml; 25% quartile 3.93; 75% quartile 5.90) was statistically significantly higher (p<0.05) than in the control group: COMP (Me=15.27 pg/ml; 25% quartile 8.86; 75% quartile 20.76 and IL-1(3 (Me=3.59 pg/ml; 25% quartile 2.75; 75% quartile 3/83). A correlation analysis in the control group revealed a positive strong correlation between COMP and IL-113 (r=+0.70; p=0.01) and a tendency toward a negative moderate association between COMP and SOD2 (r=-0.43; p=0.08); in the main group between these indicators, the connections were weak, statistically insignificant. Conclusion. Patients in the early stages of primary GA compared with healthy individuals confirmed the presence of destructive processes in the articular (hyaline) cartilage and the activation of the proinflammatory element of the cytokine profile and the enzyme level of the antioxidant system of the blood. The correlation analysis revealed a decrease in the strength of functional links in patients with GA, between the indicators of COMP — IL-1 (3 and COMP — SOD2, which indicated a change in the regulatory effects of proinflammatory cytokines and the enzyme element of the antioxidant system of the blood on the structural-metabolic state of the articular (hyaline) cartilage in the initial stage process.
