Update on the management of lupus nephritis

Abstract

Abstract The treatment of lupus nephritis still represents a therapeutic challenge for the clinician. Besides early recognition, appropriate guiding by the histologic classification at presentation as well as at relapsing disease, is essential. The most severe proliferative and mixed forms require aggressive induction therapy. Nevertheless, recent but established by RCTs advances, as low dose iv cyclophosphamide, lower doses of cor-ticosteroids and mychophenolate acid (MPA) allow us to achieve remission induction with lower toxicity without any cost in terms of efficacy. For maintenance, azathioprine and mycophenolate acid with concomitant low dose steroids have shown both good results with a slight superiority of mycophenolate acid. Emerging therapies as B cell targeting-either by depleting agents as the anti-CD 20 mAb Rituximab, or by modulating agents as the anti-Bliss Belimumab, further contribute to the effort to minimize toxicity. This review mainly focuses on the recent efforts to treat the most aggressive form of lupus nephritis effectively with the minimal possible toxicity.
