Immunosuppressive drugs and corticosteroids in the treatment of rheumatoid arthritis.

Rheumatoid arthritis is the most common form of severe inflammatory arthropathy affecting patients at a relatively early age. Although there are a number of drugs which significantly reduce pain and swelling, few alter the development of erosions and progression of joint destruction. A significant number of patients with rheumatoid arthritis develop this progressive disability and will require treatment with corticosteroids or immunosuppressive agents. In this article the use of immunosuppressive drugs and corticosteroids in the treatment of aggressive rheumatoid arthritis is reviewed. Controlled clinical trials have shown that a number of these drugs can play a significant role in reducing pain and swelling and might possibly alter the disease course in rheumatoid arthritis. Side effects of these agents, including the potential for oncogenesis, still pose major problems in their long term use. The risks and benefits of immunosuppressive and corticosteroid drug therapy must be balanced in each patient to whom they are prescribed and reviewed at frequent intervals.
