title: Therapy of systemic lupus erythematosus: new agents and new evidence.
abstract: Systemic lupus erythematosus (SLE) is a disease of relatively low prevalence with a wide range of clinical manifestations. Due in part to these two facts, there is little new evidence on the treatment of lupus. In fact, randomised controlled studies and prospective series are few and usually involve a small number of patients. Despite this, some therapies have shown to be beneficial within the last five years, while others emerge as possibilities in the near future. Among the former, antimalarials appear to be the treatment of choice for maintaining mild to moderate disease in remission. Methotrexate may be an alternative to other corticosteroid-sparing drugs, especially in patients with active arthritis and skin disease. Cyclosporin can be of use in proteinuric nephritis, although the incidence of hypertension with this drug is high. Thalidomide is useful for refractory skin lesions, but the efficacy of lower, less toxic doses is still to be studied. Immunoglobulins should probably be limited to selected patients with manifestations such as thrombocytopoenia. Experience is more limited with cladribine, fludarabine, tacrolimus, danazol and pentoxifylline. New therapies for severe SLE include mycophenolate mofetil, a potent immunosuppressive drug with a reasonable safety profile and immunoablative therapy with or without stem cell transplantation, in highly resistant cases or those with a poor prognosis. Other recently developed molecules, including anti-CD40L monoclonal antibodies (mAbs), are still under investigation.
