Kidney involvement in systemic lupus erythematosus (SLE, lupus) is an important predictor of and contributor to morbidity and mortality from lupus. The approach to treatment for lupus nephritis is that of an induction phase of therapy (with cyclophosphamide vs mycophenolate mofetil) followed by long-term maintenance therapy. However, the optimal agent for chronic immunosuppression to prevent relapse or worsening of renal SLE is unknown.
