Recent advances in the treatment of rheumatoid arthritis

Abstract

Rheumatoid arthritis (RA) affects about 0.5% to 1% of the population worldwide. Because there is no cure for this disease, the goal of therapy is to control the underlying inflammatory process and maintain or improve function. This article reviews 4 new treatments for patients with RA: leflunomide, etanercept, infliximab, and the protein A immunoadsorption column with plasmapheresis therapy.
