title: [Treatment of lupus glomerulonephritis with intravenous cyclophosphamide].
abstract: The treatment of severe lupus nephritis remains problematic. We have analysed retrospectively 17 patients with corticoresistant lupus nephritis treated with pulse cyclophosphamide. Single monthly doses (500 mg/m2) were given by intravenous infusion with a mean of 10.4 infusions per patient (3 to 18). A comparison of parameters at entry and at the end of the treatment revealed an improvement in proteinuria (4.8 vs 1.9 g/24 h; p < 0.013) whereas mean serum creatinine level and SLAM (Systemic Lupus Activity Measure) remained stable. The results were identical at follow up (mean: 14.5 months). Most of the therapeutic effect was achieved as soon as the 6th pulse. Further treatment was beneficial for four patients only. None of the studied parameters (serum creatinine level, renal biopsy, SLAM) was predictive of a response to an extended course of pulse cyclophosphamide. The infusions were definitively stopped in one patient and delayed in two others because of serious adverse effects. The data indicate that, in mean term, monthly intravenous cyclophosphamide was associated with a substantial amelioration of 24 hours urinary protein level. An amelioration of the renal function was however, uncommon.
