Actualidad en el tratamiento de la nefritis lúpica proliferativa

Lupus nephritis (LN) is an important cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). The use of aggressive immunosuppressive treatment has improved both patient and renal survival. The objectives of this therapy should be to achieve a prompt renal remission, to avoid renal flares and progression to chronic renal failure with minimal toxicity. Treatment with monthly intravenous cyclophosphamide and glucocorticoids (National Institute of Health regimen) as induction treatment and long-term administration of venous pulses of cyclophosphamide or azathioprine has become standard treatment for severe proliferative LN. Mycophenolate mofetil is an alternative to cyclophosphamide for induction and maintenance therapy of proliferative LN. There are other therapeutic options for resistant LN as more aggressive ciclophosphamide regimens, but at the expense of more toxicity, calcineurin inhibitors, intravenous immunoglobulin, immunoadsorption and therapies that selectively target B cells.
