来氟米特对IgA肾病患者血清血管内皮生长因子和内皮素水平的影响

目的 观察泼尼松联合来氟米特治疗免疫球蛋白(Ig)A肾病的疗效及安全性.方法 选取IgA肾病患者80例分为治疗组和对照组.对照组患者给予泼尼松,治疗组患者在泼尼松基础上服用来氟米特,疗程12个月.在治疗6、12个月时统计患者总有效率,检测患者血清肌酐(Scr)、尿胱蛋白酶抑制剂C(Cys C)、血尿素氮(BUN)和24 h蛋白尿(U-prot),ELISA检测患者血浆血管内皮生长因子(VEGF)和内皮素-1(ET-1)水平.结果 治疗6、12个月治疗组总有效率分别为85.0% 和90.0%,对照组为65.0% 和70.0%,两组间比较差异有统计学意义(P<0.05).治疗6、12个月患者BUN和 U-prot显著降低,且治疗组治疗效果优于对照组(P<0.05).两组患者治疗6、12个月血浆VEGF和ET-1水平下降,且治疗组下降幅度大于对照组(P<0.05).结论 泼尼松联合来氟米特可显著改善IgA肾病患者肾功能,安全有效.

Effects of leflunomide on serum vascular endothelial growth factor and endothelin in patients with IgA nephropathy

Objective To observe the efficacy and safety of prednisone combined with leflunomide in the treatment of immu-noglobulin A(IgA)nephropathy.Methods Eighty patients with IgA nephropathy were selected and divided into the treatment group and control group.The patients in the control group were given prednisone and the treatment group received prednisone plus leflunomide.The treatment course lasted for 12 months.Total effective rate,serum creatinine(Scr),urinary protease inhibitor C(Cys C),blood urea nitrogen(BUN)and 24 h proteinuria(U-prot)were measured at 6-month and 12-month treatment.Serum levels of vascular endothelial growth factor(VEGF)and endothelin-1(ET-1)were measured by enzyme-linked immunosorbent assay (ELISA).Results The effective rates at 6-month and 12-month treatment in the treatment group were 85% and 90% respective-ly,which in the control group were 65% and 70% respectively,the difference between the two groups was statistically significant (P<0.05).The BUN and U-prot levels after 6-moth and 12-month treatment were significantly reduced,moreover the effect in the treatment group was better than that in the control group(P<0.05).The levels of plasma VEGF and ET-1 after 6-moth and 12-month treatment in the two groups were decreased,moreover the decrease range in the treatment group was greater than that in the control group(P<0.05).Conclusion Prednisone combined with leflunomide can significantly improve the renal function in the pa-tients with IgA nephropathy,and it is safe and effective.
