The use of a wide range of biomarkers underlies the development of a personalized approach to the diagnosis and treatment of rheumatoid arthritis (RA). The aim of the work was to study the levels of enzymatic activity of blood serum, proinflammatory cytokines, ferritin in RA and to determine their clinical value.
The study included 128 patients with a reliable diagnosis of RA according to the criteria of EULAR / ACR 2010, as well as 33 healthy volunteers. The levels of DNAse and hyaluronidase activity of blood serum, tumor necrosis factor alpha (TNF-α), interleukin -6 (IL-6), interleukin 17A (IL-17A), ferritin were determined.
Blood serum enzymatic activity, IL-6, IL-17A and ferritin levels in RA patients were significantly higher than  those in the control group (p<0.05). TNF-α level in RA patients did not exceed the control values. The levels of serum enzymatic activity, proinflammatory cytokines and ferritin were compared with clinical, laboratory and instrumental characteristics of RA, as a result, a number of relationships were found that indicate the possibility of using the studied parameters as biomarkers in RA.
Key words: rheumatoid arthritis, DNAse serum activity, hyaluronidase serum activity, cytokines, ferritin.
