This is a phase 2 randomized controlled trial to evaluate the effectiveness and toxicity of immunosuppressive drug therapy in patients with lupus membranous nephropathy. Patients with renal biopsy documented membranous nephropathy were all treated with alternate day prednisone and were randomized to receive: 1. no additional therapy (control group), 2. intravenous cyclophosphamide up to 1.0 gm per m2 body surface area every other month for 6 total doses, or 3. oral cyclosporine up to 200 mg per m2 body surface area for a total of 11 months. Patients with glomerular filtration rates 25 to 66 ml/min/1.73 m2 body surface area were randomized only to prednisone alone or to prednisone plus cyclophosphamide. Renal function and disease activity were monitored throughout the study; physiologic measures of glomerular function (glomerular filtration rate and effective renal plasma flow) were examined at study entry and at the conclusion of the study. Comparison was made of the number of favorable outcomes of glomerular function as well as drug related toxicities observed within each treatment group. Both adjunctive cyclophosphamide and cyclosporine were more effective than alternate day prednisone alone in inducing remissions of proteinuria. Relapse of high-grade proteinuria occurred significantly more often after completing cyclosporine than after cyclophosphamide. Ten patients, who were resistant to or relapsed after prednisone alone or cyclosporine, were treated with intravenous cyclophosphamide every other month for a year, followed by quarterly pulse intravenous cyclophosphamide for a median duration of 2 years. Six patients achieved a partial remission and 2 achieved a complete remission of proteinuria. We have published the analysis of the treatment outcomes as well as a detailed multivariate analysis of the demographic and clinical factors that impact the outcomes of these patients. The study remains active to facilitate additional analyses of study data and specimens.

这是一项2期随机对照试验，旨在评价免疫抑制药物治疗狼疮性膜性肾病患者的有效性和毒性。 肾活检证实为膜性肾病的患者均接受隔日泼尼松治疗，并随机接受：1。无其他治疗（对照组），2.静脉内环磷酰胺，每隔一个月每m2体表面积最多1.0 gm，共6次剂量，或3.口服环孢霉素，最高200 mg/m2体表面积，共11个月。 肾小球滤过率为25 - 66 ml/min/1.73 m2体表面积的患者仅随机接受泼尼松单药治疗或泼尼松加环磷酰胺治疗。 在整个研究期间监测肾功能和疾病活动;在研究入组时和研究结束时检查肾小球功能的生理指标（肾小球滤过率和有效肾血浆流量）。 比较每个治疗组中观察到的肾小球功能良好结局以及药物相关毒性的数量。 环磷酰胺和环孢素联用均比隔日泼尼松单用更有效。 完成环孢霉素治疗后高级别蛋白尿复发率明显高于环磷酰胺治疗后。 10例患者，谁是耐药或复发后，泼尼松单独或环孢素，每隔一个月静脉注射环磷酰胺治疗一年，然后每季度脉冲静脉注射环磷酰胺，中位持续时间为2年。 6例患者的蛋白尿部分缓解，2例完全缓解。 我们已经发表了对治疗结果的分析，以及对影响这些患者结果的人口统计学和临床因素的详细多变量分析。 该研究仍处于活跃状态，以促进对研究数据和标本的额外分析。
