摘要
目的观察肺结核患者血清干扰素-γ(IFN-γ)及白细胞介素4(IL-4)水平与肺功能的相关性。方法75例肺结核患者(肺结核组)按病变程度分为重度25例(重度组)、中度25例(中度组)、轻度25例(轻度组),应用ELISA法检测各组肺结核患者和30例健康体检者(对照组)的外周血IFN-γ及IL-4水平并进行比较,同时检测肺结核组肺功能第1秒用力呼气量(FEV1)、第1秒用力呼气量占预计值的百分比(FEV1%)、最大用力呼气中段流量占预计值的百分比(MMEF%),并与IFN-γ及IL-4水平进行相关性分析。结果肺结核组IFN-γ,[(0.204±0.018)μg/L]及IL-4[(0.523±0.035)μg/L]水平与对照组比较差异均有统计学意义(t=7.685、6.374,均P〈0.05);肺结核组中重度组、中度组及轻度组IFN-γ及IL-4水平比较差异有统计学意义(F=10.146、7.263,均P〈0.05);肺结核中度组和重度组FEV1%、MMEF%与肺结核轻度组比较差异有统计学意义(均P〈0.05);FEV1、FEV1%、MMEF%与IL-4水平呈显著负相关(r=-0.46、-0.43,均P〈0.05),与IFN-γ水平呈显著正相关(r=0.47、0.45,均P〈0.05)。结论肺结核发病与患者血清细胞因子水平有关;肺结核患者外周血清IFN-γ及IL-4水平可能对其肺功能有一定的影响。
Objective To explore the correlation of lung function and IFN-γ and IL-4 levels in peripheral blood in pulmonary tuberculosis patients. Methods The IFN-γ and IL-4 levels in peripheral blood of 75 pulmonary tuberculosis patients ( severe 25 cases, moderate 25 cases, and mild 25 cases) and 30 healthy volunteers were measured by ELISA. Meanwhile FEV1, FEV1% and MMEF% of lung function in 75 pulmonary tuberculosis patients were measured. Results The levels of IFN-γ[ (0. 204±0. 018) μg/L] and IL-4[ (0. 523±0. 035) μg/L] in peripheral blood were significantly different both between tuberculosis group and control group and among tuberculosis patients ( severe, moderate, and mild) ( t = 7. 685,6. 374, all P 〈 0. 05 ) ; FEV1, FEV1 %, and MMEF% of severe and moderate tuberculosis patients were signiflcandy lower than those of mild tuberculosis patients and normal reference value ; In tuberculosis patients, FEVI% and MMEF% were negatively related with IL-4 level in peripheral blood (r = -0.46, - 0. 43 ,all P 〈0. 05 ) ,also significantly positively related with the IFN-γ level in peripheral blood( r = 0.47,0.45, all P 〈 0. 05). Conclusion Pulmonary tuberculosis morbility may be due to cellular levels of patients. The IFN-γ and IL-4 levels in peripheral blood could affect the lung funetion of pulmonary tuberculosis patients.
