       目的   分析原发性肾病综合征(PNS)患儿在糖皮质激素(激素)治疗后淋巴细胞亚群及免疫因子的水平变化,以探讨PNS耐药机制。方法   选取PNS患儿共71例,正常对照组108例,收集PNS患者在激素治疗前、后及正常对照组儿童的淋巴细胞亚群[CD4+ 、CD8+ 、CD4+ /CD8+ 、CD19+ 和自然杀伤(NK)细胞]及免疫因子水平,并分析激素治疗后激素敏感患儿和激素耐药患儿相关指标的差异。结果  PNS患儿淋巴细胞亚群及免疫因子水平异常,激素治疗后PNS患儿总免疫球蛋白E(IgE)水平[767.50(270.25,1 937.50)IU/mL vs 311.00(62.70,757.00)IU/mL](P=0.008)下降,而CD4+ T细胞比例[(33.88±7.42)% vs(38.25±7.16)%](P=0.004)升高,激素治疗敏感患儿NK细胞比例高于激素治疗耐药患儿[(8.39±4.60)% vs(4.72±1.99)%](P=0.034),IgE水平低于耐药患儿[311.00(62.70,633.00)IU/mL vs783.00(88.05,1 290.00)IU/mL](P<0.001)。结论  PNS患儿淋巴细胞亚群分布及免疫球蛋白水平异常,激素治疗可影响患儿CD4+ T细胞比例及IgE水平,并且NK细胞比例和IgE水平与患儿激素耐药相关。
       Objective  To evaluate the changes of lymphocyte subsets and immune factors levels in children with primary nephrotic syndrome(PNS),and explore the pathogenesis of PNS.Methods  A total of 71 patients with PNS and 108 normal control cases were selected.Flow cytometry was used to detect the concentration of lymphocyte subsets(CD4+ ,CD8+ ,CD4+ /CD8+ ,CD19+  and natural killer[NK] cells)and immune factors before and after treatment.The difference of  related factors between steroid-sensitive and steroid-resistant children after therapy were analyzed.Results  Lymphocyte subsets and immune molecule levels were abnormal in children with NPS.The level of IgE(767.50[270.25,1 937.50]IU/mL vs 311.00[62.70,757.00]IU/mL,P=0.008)was significantly decreased after therapy(P<0.05),while CD4+  T cells([33.88±7.42]% vs[38.25±7.16]%,P=0.004)were significantly increased.The level of NK cells in steroid-sensitive children was significantly higher than that in steroid-resistant children([8.39±4.60]% vs[4.72±1.99]%,P=0.034),while the level of  IgE was significantly lower than that of steroid -resistant children(311.00[62.70,633.00]IU/mL vs 783.00[88.05,1 290.00]IU/mL,P<0.001).Conclusions  The distribution of lymphocyte subsets and the level of immune factors in PNS children were abnormal.Steroid therapy could affect the levels of CD4+  T cells and IgE,and the levels of NK cells and IgE were related to steroid-resistance in PNS children.
