摘要
目的:观察辅助性17 T细胞(Th17)及其分泌的细胞因子IL-17在自身免疫性溶血性贫血(AIHA)患者中的变化并探讨其临床意义。方法:应用流式细胞术(FCM)检测治疗前与糖皮质激素治疗后AIHA患者和健康人外周血中Th17细胞的比率,同时用ELISA法检测血浆中IL-17的水平。结果:治疗前AIHA患者外周血中Th17细胞比率和血浆中IL-17的水平分别为(2.78±0.59)%和(126.4±11.6)ng/L,较健康对照[分别为(0.59±0.15)%和(52.3±4.8)ng/L]显著增高(P<0.01);治疗后,外周血中Th17细胞比率和血浆中IL-17的水平[分别为(1.05±0.28)%和(78.5±6.4)ng/L]较治疗前下降(P<0.01)。结论:AIHA患者外周血中Th17细胞的比率及其IL-17的水平均高,用糖皮质激素治疗后可下调Th17细胞的比率及IL-17的水平,有效地缓解AIHA。
AIM: To observe the percentage of Th17 cells in the peripheral blood and levels of plasma IL-17 of patients with autoimmune hemolytic anemia(AIHA)before treatment and after glucocorticoid treatment and to explore their clinical significance.METHODS: Flow cytometric assay were used to detect the rate of Th17 cells in AIHA patients.The level of plasma IL-17 in AIHA patients were measured by ELISA.RESULTS: The rate of Th17 cells and the level of plasma IL-17 were significantly increased before treatment as compared with that in normal controls [(2.78±0.59)%,(126.4±11.6)ng/L vs(0.59±0.15)%,(52.3±4.8) ng/L](P〈0.01).After treatment,The percentage of Th17 cells(1.05±0.28)% was significantly decreased(P〈0.01).The same tendency was also found in the levels of plasma IL-17(78.5±6.4) ng/L(P〈0.01).CONCLUSION: The rate of Th17 cells and the lever of plasma IL-17 significantly elevate in AIHA patients.Glucocorticoid might play a role in AIHA treatment by down-regulating Th17 cells number and concentrations of IL-17.
