Pulse methylprednisolone therapy in diffuse proliferative lupus nephritis.

The prognosis of patients with diffuse proliferative lupus nephritis is generally poor, and the majority of patients with this lesion develop progressive deterioration in renal function. Intravenous "pulses" of methylprednisolone have been advocated for the treatment of severe nephritis. In this study, 15 patients with biopsy-proven diffuse proliferative lupus nephritis were treated with oral high-dose prednisone therapy, initially 2 mg/kg/day. They were compared with seven patients with similar renal pathology treated with six daily pulses of methylprednisolone (30 mg/kg/day, not to exceed 1 gm/day), followed by prednisone orally, initially 2 mg/kg/day. There were no deaths in either group and the side effects of therapy were similar in the two groups. Pretreatment GFRs for the pulse and high-dose groups were similar. There was a more rapid improvement in GFR following pulse therapy, but the long-term effects on renal function for the two modes of therapy were the same.
