Rediscovering the therapeutic use of glucocorticoids in rheumatoid arthritis

This review will focus on new information obtained on how to apply glucocorticoids in the treatment of rheumatoid arthritis, aiming at an optimal risk-benefit ratio. Moreover, advances in the development of new preparations such as liposomal glucocorticoids will be discussed.

In early rheumatoid arthritis, treatment regimens with a disease-modifying drug and initially medium-dose glucocorticoids (>7.5 but ≤30 mg prednisone equivalent) are noninferior compared with regimens with disease-modifying drugs and initially high-dose glucocorticoids (>30 mg prednisone equivalent) and have repeatedly been proven to be more effective than methotrexate monotherapy. Use of glucocorticoids following such a scheme during a period of 6 months to 2 years was not associated with increased mortality, nor with substantial bone loss if bone protective measures had been taken. New drug delivery systems, and in particular long-circulating liposomes, aiming at enhancing the biodistribution and the target site accumulation of glucocorticoids and thereby improving the balance between their efficacy and toxicity, are promising; more results on the effects in rheumatoid arthritis patients are expected to be reported during the years to come.

Combination therapy including methotrexate and glucocorticoids should be the initial treatment in patients with early rheumatoid arthritis. Treatment regimens including medium-dose glucocorticoids are noninferior compared with regimens with initially high-dose glucocorticoids. Studies on new glucocorticoid preparations and new drug delivery systems improving the balance between efficacy and toxicity of glucocorticoid therapy are ongoing.
