目的探讨免疫性血小板减少症(ITP)患者免疫抑制治疗前后免疫细胞亚群及血清中
相关细胞因子水平的变化及意义。方法应用流式细胞术检测20例临床诊断为I,I’P的患者和20例 正常对照的免疫细胞亚群,并采用ELISA法检测血清TNFa、IL-2、IL4、IL-6、IL一10、IL一1l、IL一17、IL-27、 转化生长因子p(TGFl3)和血小板生成素(TPO)等水平。结果治疗前ITP组cD,+T、cD。+T细胞百 分比及CD。+T/CD。+T比值显著低于正常对照组[(62.66±6.58)%比(69.93±4.81)%,(29.46± 5.02)%比(39.08 4-3.50)%,0.97±0,35比1.56±0.26,P值均<0.05],CD8+T及CD。9+B细胞百分 比高于正常对照组[(30.28 4-4.63)%比(25.90±3.06)%,(18.92 4-4.27)%比(13.17 4-3.64)%, P值均<0.05]。治疗后ITP组CD,+T、CD。+T细胞百分比及CD4+T/CD。+T比值高于治疗前[(71.49± 5.16)%比(62.66 4-6.58)%,(39.25 4-3.21)%比(29.46±5.02)%,1.56 4-0.28比0.97±0.35, P值均<0.05],CD。+T细胞百分比及CD。。+B细胞百分比低于治疗前[(25.16±3.45)%比(30.28± 4.63)%,(11.98 4-3.68)%比(18.92±4.27)%,P值均<0.05]。治疗前ITP组血清IL4、IL-6、

The present
study suggests that the aberrant immunocyte subsets and cytokines
involved in the pathogenesis of n1P.
Hyper-function of T}12 and Thl7,dysfunction of Treg ceHs,up—regulation of IL-27,IL・11,TPO and other factors may contribute to the pathogenesis of 17m

IL.11、IL.17、TPO水平显著高于正常对照组,TG邛水平显著低于正常对照组(P值均<0.05);治疗后
ITP组血清IL-4、IL-6、IL.11、IL.17、TPO水平显著低于治疗前,TGF0、IL.27则显著高于治疗前(P值 均<0.05)。结论ITP患者存在免疫细胞亚群紊乱及细胞因子水平异常。ITP发病可能与Th2及 Thl7细胞功能亢进、调节性T细胞功能减低以及IL-27、IL.1 1、TPO水平增高等因素有关。
