Treatment of systemic lupus erythematosus

The treatment of systemic lupus erythematosus (SLE) is mainly based on a number of "traditional" drugs such as corticosteroids, antimalarials, azathioprine and cyclophosphamide. However, this scenario is rapidly changing due to the introduction of new compounds. Some of these new agents have been successfully used in other diseases, while others are being specifically designed to interfere with the immune abnormalities seen in SLE. As our knowledge on the mechanisms of immune response increases, new drugs that can interfere with T and B cell interaction and activation, production of anti-dsDNA autoantibodies, immune-complexes deposition and cytokine activation have been developed and some of these are now under investigation in SLE. Although initial data regarding their safety and efficacy are encouraging, caution must be taken before these drugs are considered as the treatment of choice for specific SLE manifestations. Specifically, controlled clinical trials with sufficient number of patients are necessary. If the promising results already available are confirmed, the use of these drugs might represent the keystone in the future management of SLE and other autoimmune diseases.
