Abstract:

目的:研究慢性阻塞性肺疾病(COPD)患者血液及痰液IL-33/sST2水平与COPD肺动脉高压形成的关系。方法:将确诊COPD急性加重期的31例患者,依心脏彩超结果分为COPD伴肺动脉高压组(COPD-PAH)和COPD不伴肺动脉高压组(COPD-non PAH),取血液及痰液标本,ELISA法检测IL-33、sST2和IL-6,并进行多因素Logistic分析。25例健康志愿者为对照组(HC)。结果:1COPD-PAH组血清sST2水平显著高于COPD-non PAH组(P<0.05),两组血清IL-33、IL-6和痰液IL-33、sST2、IL-6水平无统计学差异。两组间多因素Logistic分析仅PaO2进入方程。2COPD-PAH组血清IL-33、sST2和IL-6水平显著高于HC组(P<0.05);COPD-non PAH组血清IL-33和IL-6水平显著高于HC组(P<0.05),但血清sST2水平与HC组无统计学差异。结论:IL-33、sST2、IL-6参与COPD的气道及全身炎症过程。sST2可能参与COPD-PAH形成的炎症机制
