Le traitement de la polyarthrite rhumatoïde. Évolution des idées et des stratégies

Abstract

Treatment of rheumatoid arthritis. Evolution of concepts and strategies. Introduction. — The treatment of rheumatoid arthritis includes non-steroid anti-inflammatory drugs (NSAID), low-dose steroids and drugs which modify the evolution of the disease (disease modifying anti-rheumatic drugs, [DMARD]). In the last few years, the long-term efficiency of the recommended treatment strategies in rheumatoid arthritis has been a matter of debate and their basic assumptions have been challenged. Numerous studies were undertaken to settle the question. They tried to delineate the rules for an optimal use of current drugs and other therapeutic means. Current knowledge and key points. — Rheumatoid arthritis is a crippling disease. It decreases life expectancy and irreversible bone and joint damage may develop even in the first months of evolution. The sooner the prescription of DMARD, the higher the frequency and quality of rheumatoid arthritis improvement and, in the long-term, the lesser the functional impairment. Low dose steroids, when administered early, can slow down the development of radiologic lesions. Some of their effects are thus closer to those of DMARD than to those of symptomatic treatment. NSAID are at least as equally dangerous as DMARD and possibly more so in terms of the potential number of severe side effects. The combination of several DMARD does not increase their overall toxicity. An evaluation of the most efficient combinations and of the clinical situations in which combinations show promise of improved results is in progress. Future prospects and projects. — At present, the tendency is to treat early and intensively, in order to obtain complete remission, improve evolution and reduce functional impairment. This strategy requires early diagnosis and early evaluation of prognosis of rheumatoid arthritis. Rheumatoid arthritis with benign evolution would not warrant intensive treatment. Studies are in progress to evaluate the prognostic factors in early rheumatoid arthritis that would enable us to adapt the strength of initial treatment to the disease's putative severity.
