Abstract

To evaluate the results, the long-term prognosis and the rates of complication of an immunosuppressive regimen with corticosteroids and cyclophosphamide in the treatment of the nephritis of systemic lupus erythematosus, 21 patients with lupus glomerulonephritis were studied. Renal biopsies were performed in 17/21 of them and indicated diffuse proliferative (6 patients), diffuse mesangial (4) and membranous (7) glomerulonephritis. Treatment was structured in 4 phases: 1) induction with methylprednisolone 250 mg i.v. for 7-14 days, and cyclophosphamide 100-200 mg p.o., q.d., or 20 mg/kg i.v. every 28 days; 2) maintenance with prednisone p.o., 2 mg/kg q.o.d. for 45 days, and cyclophosphamide as before; 3) tapering, with reduction of prednisone by 15% each month for 4 months; 4) indefinite maintenance with prednisone slowly tapered to the least effective q.o.d. dose and cyclophosphamide discontinued after six months of treatment. This cycle was repeated in the event of a relapse. After a first immunosuppressive cycle, 20/21 patients achieved remission of glomerulonephritis. Plasma creatinine fell from 97 +/- 6 to 80 +/- 3 mu Mol/l (p <0.01). Proteinuria fell from 2,1 +/- 0.4 to 0.2 +/- 0.4 g/d (p <0.0001) and the nephrotic syndrome, present in 8 patients, disappeared. After an average of 20 +/- 7 months, 8 patients relapsed: all remitted again after a repeat cycle, but 1 later progressed to end-stage renal failure during pregnancy. After an average of 56 months 4 out of these 8 patients relapsed again: 1 progressed to end-stage renal disease following an abortion and 3 remitted completely after a third cycle. Thus, 18 out of 21 patients are presently in remission with an average dose of prednisone of 13.7 mg/day after an average follow-up of 52 +/- 38 months (range 2 to 156). Three patients are presently off treatment. In 16 patients with extended follow-up of 2 to 13 years, anti-nuclear antibodies, anti-DNA antibodies, albuminuria and cylindruria fell below post-cycle levels (p <0.001 for all), We conclude that intensive immunosuppression with steroids and cyclophosphamide can achieve excellent long-term results in the treatment of systemic lupus with glomerulonephritis.
