Assessment of the Significance of Diagnostic Criteria in Rheumatoid Arthritis

Abstract

Rheumatoid arthritis (RA) is an immuno–inflammatory (autoimmune) rheumatic disease characterized by chronic erosive arthritis and systemic damage to internal organs, leading to early disability. The aim of the study is to identify the most significant diagnostic criteria for RA and undifferentiated arthritis (NDA). The study involved 103 patients who were divided into 2 main groups, 53 patients with RA (group I) and 50 patients with NDA (group II). The results of the study showed that when studying the seropositivity of the Russian Federation, IgM - among RA patients was noted in 41 (77.3%); among NDA patients, IgM seropositivity according to RF was noted in 34 (64.7%) patients, the average concentration of ADC was 20.4±12.04 OEd/ml. Thus, using the research methods conducted by us, it can be considered as promising methods for a more objective assessment of inflammatory changes in joints.
