Proliferative glomerulonephritis is a common and severe manifestation of systemic lupus erythematosus (SLE) that usually requires intensive therapy with high doses of glucocorticosteroids and cytotoxic drugs, such as intravenous (IV) cyclophosphamide (CYC). The objective of this Trial is to compare leflunomide (LEF) and azathioprine (AZA), in terms of efficacy and toxicity, as remission-maintaining treatment of proliferative lupus glomerulonephritis, after a remission-inducing therapy with a short-course IV CYC regimen. The hypothesis of this trial is that LEF is non-inferior to AZA.
Leflunomide, 20 mg/d, ORAL ,each day. Number of Cycles: until progression or unacceptable toxicity develops. Predonine, 10 mg/d, ORAL, each day. If extra renal flare occurs, the dose of predonine may be increased to 1mg/kg/day for not more than 2 weeks.
Azathioprine,50-100 mg/d, ORAL ,each day . Number of Cycles: until progression or unacceptable toxicity develops. Predonine, 10 mg/d, ORAL, each day. If extra renal flare occurs, the dose of predonine may be increased to 1mg/kg/day for not more than 2 weeks.
