摘要: [摘要] 目的 观察不同年龄活动性肺结核患者治疗过程的临床表现以及 T 细胞亚群的动态改变,探讨老年
肺结核患者 T 细胞免疫状态与疾病恢复的关系。方法 选择初治菌阳肺结核患者 80 例,根据年龄分为 A 组(年
龄 <60 岁, 40 例)、 B 组(年龄 ≥60 岁, 40 例)。 A 、 B 组均完成 2HRZE / 4HR 抗结核治疗。分别于明确诊断后治疗
前( T 0 期)、治疗 1 个月(
T 1 期)、治疗 6 个月( T 6 期) 3 个不同时点,观察患者临床症状、痰涂片转阴情况、胸部 X 线
及 T 细胞亚群变化,比较 2 组在各治疗阶段免疫状态的动态变化。结果 T 1 期时 A 组 临床疗效、痰抗酸染色转阴
率及影像学好转率均高于 B 组,而 T 6 期 2 组差异无统计学意义。 T 细胞:组间、时点间、组间·时点间交互作用差
异均有统计学意义( P <0.05 )。 Th 细胞:组间、时点间差异有统计学意义(
P <0.05 ),组间·时点间交互作用差异
无统计学意义( P >0.05 )。 Ts 细胞:组间差异有统计学意义(
P <0.05 ),时点间、组间·时点间交互作用差异无统
计学意义( P >0.05 )。 Th / Ts 比值:组间差异有统计学意义(
P <0.05 ),时点间、组间·时点间交互作用差异无统
计学意义( P >0.05 )。结论 老年继发性肺结核患者 T 细胞免疫功能较中青年患者低,且直接影响老年肺结核患
者治疗效果以及治愈时间。
