目的 研究老年慢性阻塞性肺病(COPD)患者血清IL-33水平与其病程分期的相关性。方法 选择60例老年COPD患者作为观察组,按病程分期分为稳定期组和急性加重组,另选择15例非COPD老年患者作为对照组;分别检测血清IL-33水平。结果 各组组间比较结果显示,AECOPD组和COPD稳定期组的血清IL-33水平均高于对照组(P<0.05),其中,AECOPD组的比COPD稳定期组的更高(P<0.05)。结论 血清IL-33水平在老年COPD患者中增高,急性加重期更明显,提示IL-33在老年人COPD发生、发展中可能起重要作用。

Objective To have relevant research between serum IL-33 level and the stage of disease in elderly patients with chronic obstructive pulmonary disease(COPD). Methods 60 elderly patients with COPD were selected as the observation group, who were divided into stable COPD group and AECOPD group. The other 15 patients with non-COPD were selected as the control group. The serum IL-33 levels were detected respectively. Results The comparison results between the groups showed that the serum IL-33 levels in the AECOPD group and the stable COPD group were higher than those in the control group(P<0.05), which was higher in the AECOPD group than in the COPD group(P<0.05). Conclusion Serum IL-33 levels were increased in elderly patients with COPD, the increase in acute exacerbation was more obvious, suggesting that IL-33 may play an important role in the occurrence and development of COPD in the elderly.
