title: [The role of biomarkers in diagnostics and forecasting of effectiveness of modern therapy of rheumatoid arthritis].
abstract: The rheumatoid arthritis is one of the most severe and widespread systemic inflammatory autoimmune diseases. The modern laboratory diagnostic of rheumatoid arthritis includes detection of large spectrum of biomarkers (autoantibodies, indicators of acute phase of inflammation, cytokines, markers of activation of endothelium, subpopulations of lymphocytes, products of metabolism of bone and cartilaginous tissue, genetic markers) in blood, synovial fluid, and synovial tissue. Alongside with common techniques of immunodiagnostics, the multiplex analysis of biomarkers based on genetic, transcript and proteomic technologies is applied. The results of identification of biomarkers are an important instrument of early diagnostics, activity evaluation, severity of disease course and disease prognosis and effectiveness of applied therapy. Among biomarkers associated with rheumatoid arthritis the most clinical value have antibodies (rheumatoid factor class IgM, antibodies to citrullinized proteins) and acute phase indicators (erythrocyte sedimentation rate, C-reactive protein) which are diagnostic criteria of rheumatoid arthritis and can be used in evaluation of prognosis of this disease. On basis of multi-parametric analysis of 12 key proteins of blood serum the new index of activity of rheumatoid arthritis (Vectra DA) is developed Nowadays, the potential biomarkers are detected providing to implement immunologic monitoring and prognosis of effectiveness of therapy of rheumatoid arthritis with genetic engineering biologic preparations. The laboratory tests are developed to evaluate immunogenicity of genetic engineering biologic preparations and diagnostic of latent tuberculosis infection in patients with rheumatoid arthritis against the background of therapy with using this group of pharmaceuticals.
