Abstract

The epidemiology, pathophysiology, clinical features, diagnosis, and clinical course of rheumatoid arthritis (RA) and the role of disease-modifying antirheumatic drugs (DMARDs) in its treatment are reviewed. RA, a widespread disease affecting people of all races and sexes around the world, has an unknown and perhaps multifactorial etiology. Conflicting evidence supports an immune-complex, infectious, metabolic, or genetic basis for RA. The disease affects diarthrodial joints and begins as an immune response to unknown antigenic stimuli. A proliferative process ensues, leading to formation of a vascular lesion called a pannus, which then infiltrates into cartilage, subchrondral bone, and tendon. This destructive phase leads to classic RA symptoms of pain, limitation of motion, swelling, heat, and redness of the affected joint. Symptoms and laboratory tests form the basis for diagnosis. For most RA patients, conservative therapy provides substantial benefit. In those patients who suffer from unrelenting and progressively destructive disease, more aggressive intervention is necessary to prevent permanent disability. The DMARDs are reserved for treatment of this group of patients. DMARDs include such diverse agents as the gold comp...Continue Reading
