摘　　要：Background Lupus nephritis （LN） is one of the most serious manifestations of systemic lupus erythematosus.Although there have been substantial improvements in LN treatment over the last decade,the outcome remains unoptimistic in a considerable percentage of patients.The aim of this study was to evaluate the efficacy and safety of mizoribine （MZR）,a novel selective inhibitor of inosine monophosphate dehydrogenase,as induction treatment for active LN in comparison with mycophenolate mofetil （MMF） and intravenous cyclophosphamide （CYC）.Methods Ninety patients with active LN were observed.Thirty patients were given MZR orally at the dose of 300 mg every other day.Thirty patients took MMF at 2 g per day in two divided doses.Thirty patients received CYC intravenously 0.5 g every 2 weeks.Therapeutic effects and adverse events （AEs） were evaluated at the end of 24-week treatment.Oneway analysis of variance （ANOVA） followed by Dunn＇s test was applied to compare the difference among the groups.For comparing categorical data between two groups,χ^2 test was employed.Results Early responses at week 12 were achieved by 73.3%,90.0%,and 96.7% in MZR,MMF,and CYC groups,respectively.There was no significant difference in the complete remission rates （22.7%,24.0%,and 25.0%,respectively） or overall response rates （68.2%,72.0%,and 75.0%,respectively） among the three groups at week 24.The most prominent drop-down of Systemic Lupus Erythematosus Disease Activity Index scores was observed in MMF or CYC group,and the decline of health assessment questionnaire scores in MZR or MMF group was more prominent than that in the CYC group at week 12.Serum complement 3 （C3） or C4 levels were elevated in all groups after the treatments.CYC was more effective in inhibiting anti-double-stranded DNA antibody,while MZR was more effective in inhibiting antinuclear antibody.The incidences of AEs in patients treated with CYC were significantly higher than those in patients treated with MZR or MMF （24.2% for CYC vsBackground Lupus nephritis （LN） is one of the most serious manifestations of systemic lupus erythematosus.Although there have been substantial improvements in LN treatment over the last decade,the outcome remains unoptimistic in a considerable percentage of patients.The aim of this study was to evaluate the efficacy and safety of mizoribine （MZR）,a novel selective inhibitor of inosine monophosphate dehydrogenase,as induction treatment for active LN in comparison with mycophenolate mofetil （MMF） and intravenous cyclophosphamide （CYC）.Methods Ninety patients with active LN were observed.Thirty patients were given MZR orally at the dose of 300 mg every other day.Thirty patients took MMF at 2 g per day in two divided doses.Thirty patients received CYC intravenously 0.5 g every 2 weeks.Therapeutic effects and adverse events （AEs） were evaluated at the end of 24-week treatment.Oneway analysis of variance （ANOVA） followed by Dunn＇s test was applied to compare the difference among the groups.For comparing categorical data between two groups,χ^2 test was employed.Results Early responses at week 12 were achieved by 73.3%,90.0%,and 96.7% in MZR,MMF,and CYC groups,respectively.There was no significant difference in the complete remission rates （22.7%,24.0%,and 25.0%,respectively） or overall response rates （68.2%,72.0%,and 75.0%,respectively） among the three groups at week 24.The most prominent drop-down of Systemic Lupus Erythematosus Disease Activity Index scores was observed in MMF or CYC group,and the decline of health assessment questionnaire scores in MZR or MMF group was more prominent than that in the CYC group at week 12.Serum complement 3 （C3） or C4 levels were elevated in all groups after the treatments.CYC was more effective in inhibiting anti-double-stranded DNA antibody,while MZR was more effective in inhibiting antinuclear antibody.The incidences of AEs in patients treated with CYC were significantly higher than those in patients treated with MZR or MMF （24.2% for CYC vs
