老年重症肺炎患者细胞免疫功能改变及胸腺肽α1疗效观察

目的 研究老年重症肺炎患者细胞免疫功能的变化并观察胸腺肽α1干预的效果.方法 测定66例老年重症肺炎患者和34例老年肺炎非重症患者的T细胞亚群及自然杀伤(NK)细胞.将66例老年重症肺炎患者分为治疗组34例,对照组32例.治疗组给予胸腺肽α11.6 mg皮下注射1次/d,连续7 d,1周后改为2次/周.对照组仅以常规抗感染治疗.2周后测定两组的T细胞亚群和NK细胞.结果 老年重症肺炎患者CD3、CD4、CD8、NK细胞[分别为(43.54±18.97)%、(25.43±12.72)%、(16.68±9.30)%、(13.52±4.66)%]较非重症肺炎组[分别为(45.46±10.43)%、(38.47±8.20)%、(22.36±8.06)%、(17.87±7.11)%]明显减低(t值分别为-6.779、-5.85、-3.161、-3.285,均P＜0.05).治疗组与对照组治疗后比较,CD3、CD4、CD4/CD8、NK细胞[分别为(64.22±5.53)%、(31.70±4.38)%、(1.27±0.91)、(17.67±4.56)%与(61.53±13.41)%、(26.07±4.31)%、(0.97±0.22)、(15.44±3.82)%]增高(F值分别为5.591、11.526、8.934、4.564,均P＜0.05).治疗组抗生素应用时间、平均住院时间[(14.17±2.51)d、(12.69±2.80)d]均低于对照组[(14.42±2.79)d、(15.04±3.58)d](t值分别为-3.152、-2.690,均P＜0.05).结论 老年重症肺炎患者细胞免疫功能减低.胸腺肽α1治疗能够改善老年重症肺炎患者免疫功能,提高抗感染治疗效果.

Abstract：

Objective To investigate the cellular immune function changes and the effect of thymosin alpha-1 on the changes in elderly patients with severe pneumonia. Methods T cell subset and natural killer (NK) cell were detected in 66 elderly patients with severe pneumonia and 34 elderly patients with common pneumonia. The severe pneumonia patients were randomly divided into 2 groups: the treatment groups (34 cases) and the control group (32 cases). All patients received conventional therapy of pneumonia. The treatment group received 1.6 mg of thymosin alpha-1 through subcutaneous injection once a day for a week and twice a week later. Results The levels of CD3, CD4, CD8 and NK cell were lower in elderly patients with severe pneumonia than in patients with common pneumonia [(43.54%±18.97%) vs. (45.46%±10.43%), (25.43%±12.72%) vs. (38.47%±8.20%), (16.68%±9.30%) vs. (22.36%±8.06%), (13.52%±4.66%) vs. (17.87%±7.11%), t=-6.779、-5.85、-3.161、-3.285 respectively all P＜0.05]. The levels of CD3, CD4, CD4/CD8 and NK cell increased significantly after treatment in treatment group [(64.22%±5.53%) vs. (61.53%±13.41%), (31.70%±4.38%) vs. (26.07%±4.31%), (1.27%±0.91%) vs. (0.97%±0.22%), (17.67%±4.56%) vs. (15.44%±3.82%), F=5.591,11.526,8.934,4.564 respectively, all P＜0.05]. The duration of antibiotic injection and length of stay were lower in treatment group than in control group [(14.17±2.51) d vs. (14.42±2.79) d, (12.69±2.80) d vs. (15.04±3.58) d, t=-3.152、-2.690 respectively, all P＜0.05]. Conclusions The immune function of the elderly patients with severe pneumonia is lower. Thymosin alpha-1 can improve the immune function of the elder patients with severe pneumonia and is helpful for controlling an infection.
