Disease-modifying antirheumatic drug (DMARD) therapy is now clearly accepted as the primary treatment for rheumatoid arthritis, with an increasing emphasis on use of combination therapy. Data on combination therapy have highlighted the difficulties in performing these studies and the large number of patients required to produce meaningful results. Combination studies have focused on use of rapidly decreasing high-dose steroids as a part of the combination and emphasize the importance of using patients with early rheumatoid arthritis. Even with relatively aggressive use of DMARDs, the majority of patients develop erosions. Adverse reactions to DMARDs continue to concern clinicians, although evaluation of the frequency of these events has led to a reappraisal of previously accepted monitoring strategies in some cases. For example, it may not be cost-effective to subject patients on antimalarials to regular review by an ophthalmologist because of the low frequency of serious eye defects. Studies have also identified risk factors for the development of pulmonary toxicity in association with methotrexate. That DMARDs are effective in treating rheumatoid arthritis is beyond question-just how effective they are and what combinations of DMARDs will show improved efficacy will provide data for the next annual review.
