目的:分析非结核分枝杆菌(nontuberculosis mycobacterium, NTM)感染患者外周血免疫细胞表达率的改变以及临床意义。方法:选择2016年4月至2017年4月期间苏州市第五人民医院住院的69例NTM感染患者作为病例组,选取同期本院健康体检者66例作为对照组。采用流式细胞术对健康对照组和NTM感染患者(NTM组)外周血免疫细胞表达率进行检测,并比较各组之间的差异。进一步根据感染部位的差异将NTM组分为单侧感染组(29例)和双侧感染组(40例),比较两组之间免疫细胞表达水平的差异。结果:与对照组相比较,NTM组的总的T淋巴细胞表达率没有显著改变,而B淋巴细胞与单核细胞表达率出现显著上调[(10.50±0.56)%比(12.26±0.57)%,(5.61±0.24)%比(6.72±0.32)%,n t值分别为2.209和2.774,n P值均0.05),而双侧感染组的CD8n +CD28n +T细胞表达比例较单侧感染组显著下降[(21.99±1.02)%比(26.21±1.52)%,n t=2.397,n P0.05). While CD8n + CD28n + T cells were significantly decreased[(21.99±1.02)% vs (26.21±1.52)% , n t=2.397, n P<0.05], and CD8n + CD28n -T cells were significantly up-regulated[(24.48±1.90)% vs (18.19±1.60)%, n t=2.404, n P<0.05] in the bilateral infection group compared with the unilateral infection group.n Conclusion:The expression rate of some immune cells in peripheral blood of patients with NTM changed significantly, which may have an important impact on the occurrence and development of the disease.
