摘 要: | Objective To investigate the efficacy and safety of leflunomide as induction and mainten-ance therapy for class Ⅴ lupus nephritis. Methods Sixteen patients with lupus nephritis (of which, three proven with Ⅴ +Ⅲ, six with Ⅴ+Ⅳ ), proven by renal biopsies, were included in this study. ALL patients rec-eived LEF plus prednisone treatment. For induction therapy, all patients were given an initial loading dose of LEF 60 mg daily for three days, followed by 20 mg daily for the whole induction treatment period. Prednisone was given starting from 0.8 mg per kilogram daily, then tapered four weeks later. After twenty-four weeks, the dosages of LEF and prednisone were 10 mg/d, 5~10 mg/d respectively during maintenance therapy. We asses-sed total remission rates in the end of twenty-four weeks, as well as the changes of system lupus erythematosus disease activity index (SLEDAI), urinary protein per twenty-four hours (24 h Upr), serum albumin, serum creatinine level, complement C3, complement C4, C reactive protein, serum titer of ANA and anti-dsDNA be-fore treatment, 12 weeks, 24 weeks and 48 weeks after treatment respectively. Meanwhile, seven patients received repeated renal biopsies after completing induction therapy, so we compared pathological activity index (AI) and chroniciry index (CI) between pre-therapy and post-therapy at the same time. T and t' test were selected. Results Sixteen patients were followed-up. After 24 weeks induction therapy, the total remission rate was 75.0%; SLEDAI was significantly lower than pre-therapy (15.4±3.5) vs (6.9±1.7), P<0.05]; 24 h Upr was also significantly lower than pre-therapy (5.8±2.2) g vs (l.3±0.5) g, P<0.01 ]. Unfortunately, all seven patients performed repeated renal biopsies with class Ⅴ lupus nephritis again histologically, of which two were transformed other cater-ofies. Comparing with that of pre-therapy, AI was improved after therapy (2.4±0.9) vs (1.7±0.8), P<0.05]. However, CI indicated no difference. Adverse events including major infection occurred in four patients. The adverse events happened at the 12 th week after treatment. Conclusion The efficacy of LEF plus corticoster-oids as induction and maintenance therapy for class Ⅴ lupus nephritis is remarkable and the tolerance of patients is good.
