title: Immunosuppressive treatment for idiopathic nephrotic syndrome with corticosteroids and cyclophosphamide: factors associated with a favourable outcome.
abstract: OBJECTIVE
  We report the results of a combined immunosuppressive schedule for the treatment of patients with idiopathic nephrotic syndrome, in which prednisone and cyclophosphamide were given in four phases: induction, maintenance, tapering and discontinuation.
  
  
  METHODS
  Sixty-seven patients with nephrotic syndrome, followed for an average of 7.1 +/- 4.5 years, were studied. Treatment outcomes were remission, progression, end-stage renal disease and death.
  
  
  RESULTS
  At the end of the follow-up, 72% of patients maintained a complete remission. Stepwise logistic regression showed that the cumulative dose of cyclophosphamide was the only independent predictor of a favourable outcome, being associated both with complete remission of the nephrotic syndrome and with lack of progression to chronic renal failure.
  
  
  CONCLUSIONS
  We suggest that the combination treatment may be indicated in all histological subgroups of nephrotic syndrome, provided that prednisone is given at high doses on alternate days, cyclophosphamide is given for 6 months, and relapses are treated with the same schedule. The adverse effects of treatment, however, require the adoption of a programme to prevent bone loss, infertility, bladder cancer and infections.
