Update on treatment of rheumatoid arthritis.
OBJECTIVE
To review current treatment of rheumatoid arthritis (RA), as well as recent advances.


METHODS
MEDLINE search from 1990 to 1998 for human studies using search terms "rheumatoid arthritis"; "cyclooxygenase inhibitors" combined with "anti-inflammatory agents, nonsteroidal"; "tumor necrosis factor" limited to "antagonists and inhibitors"; "isoxazoles."


RESULTS
RA is a chronic inflammatory disease characterized by symmetrical joint involvement, usually of the small joints of the hands and feet. Although the hallmark of the disease is inflammation of joints, other organ systems--including the eyes, blood vessels, lungs, and cardiopulmonary system--may also be involved. Treatment of RA requires both drug and non-drug approaches. Current drug therapy consists of combinations of nonsteroidal anti-inflammatory drugs (NSAIDs) and disease-modifying antirheumatic drugs (DMARDs). Corticosteroids are also used either for short-term treatment during initiation of therapy, in bursts during acute disease flares, or chronically in low doses. A number of promising new agents are in development. NSAIDs with preferential inhibition of cyclooxygenase II may offer a better safety profile than existing agents. Leflunomide and biological agents such as etanercept may provide benefit for patients who fail to achieve adequate response from conventional therapy.


CONCLUSIONS
Traditional approaches to treatment of RA include NSAIDs combined with DMARDs. New agents just reaching the market represent important advances and have the potential to make a positive impact on treatment of RA.
