[Current concepts of pharmacotherapy in rheumatoid arthritis]

Although there were essential achievements in understanding the pathogenesis of rheumatoid arthritis (RA), the mentioned pathologies still remain one of the most complicated problems in practical medicine. Rheumatologists arrived, during the last decade, at a conclusion on a need in an early aggressive therapy, because the destructive changes develop in joints yet during the first 4 months starting from the onset of initial RA clinical signs. The approach towards treatment by non-steroid anti-inflammatory drugs changed with respect to the risk factors related with the onset of potential complications and to choosing the safest drugs, which became possible owing to the development of drugs, whose action is aimed at suppression of cyclo-oxygenase-2 (COG-2). The group of "disease-modifying antirheumatic drugs" (DMARD) was added two new cytotoxic drugs, i.e. cyclosporin A and leflunomid. A concept of combined therapy by 2 or 3 DMARD was elaborated to ensure an effect in case of tolerance to monotherapy. The feasibility and safety of therapy by glucocorticosteroids both with small daily doses and with pulse therapy in extra aggressive RA variations were proven. The use of biological agents, i.e. of monoclonal antibodies to TNF alpha and IL-4 or of their receptors antagonists, is an absolutely new trend in RA treatment. Treatment safety is in the focus of attention; monitoring methods were designed to ensure such safety.
