摘要 目的:探讨脓毒性休克患者的外周血CD4+CD25+CD127low调节性T细胞(Treg)水平及其与疾病严重程度的相关性。方法:选择40例确诊脓毒性休克患者(脓毒性休克组)和健康对照组30例,收集其一般临床资料,行急性生理学及慢性健康状况(APACHEⅡ)评分,采用流式细胞术检测健康对照组和脓毒性休克组外周血中Treg细胞百分比,根据28 d存活情况分为死亡组与存活组,分析两组Treg细胞水平的差异及与APACHEⅡ评分的关系。结果:脓毒性休克组Treg细胞比例为4.76±2.24,较健康对照组(2.46±0.80)明显升高;在脓毒性休克患者死亡组Treg细胞比例(6.90±1.74)显著高于存活组(3.33±1.05),且与APACHEⅡ评分之间呈明显的正相关,相关系数为0.831(P<0.01)。结论:脓毒性休克患者外周血Treg细胞水平明显升高,且与疾病严重程度相关,提示脓毒性休克患者呈严重的免疫抑制状态。
