摘要 目的 研究血液肿瘤患者化疗后中性粒细胞缺乏(简称粒缺)伴感染时的Th1/Th2细胞因子谱的水平,探讨其在病情发展中的意义.方法 采用流式细胞微球阵列(CBA)技术测定128例血液系统肿瘤化疗后粒缺伴感染患者(粒缺伴感染组)、30例血液系统肿瘤化疗后粒缺无感染患者(粒缺无感染组)的外周血Th 1/Th2细胞因子谱,同步进行血培养,对比30例健康体检者(健康对照组),探讨Th1/Th2细胞因子谱的临床意义.结果 (1)30例健康对照组和30例粒缺无感染组的Th1/Th2细胞因子谱水平比较差异无统计学意义(P>0.05).128例粒缺伴感染组IL-4、IL-6、IL-10、TNF和INF-γ水平均高于粒缺无感染组(P<0.05),尤以IL-6、IL-10升高最为明显.(2)128例粒缺伴感染组中血培养阳性23例(脓毒血症患者),发生感染性休克7例,其中血培养阳性者IL-6、IL-10、TNF水平均明显高于血培养阴性者(P<0.05),感染性休克者IL-6、IL-10水平均明显高于无感染性休克者(P<0.05).结论 (1)中性粒细胞绝对数不影响Th1/Th2细胞因子水平;(2)根据Th1/Th2细胞因子谱的改变,在血液肿瘤患者化疗后中性粒细胞缺乏伴感染时可作为一个早期指导用药的指标;(3)根据Th1/Th2细胞因子谱中的IL-6和IL-10水平,可作为判断病情严重程度的指标.
