摘要 目的检测支气管哮喘急性发作者血清中白介素(IL)-33、可溶性ST2(sST2)的水平,研究他们在支气管哮喘炎症反应中的作用。方法收集41例支气管哮喘急性发作者和33例健康对照者,按严重程度将支气管哮喘患者分为轻度、中度、重度发作,采用酶联免疫吸附法(ELISA)检测41例支气管哮喘急性发作者和33例健康对照者血清中的IL-33、sST2、免疫球蛋白E(IgE)的水平,血细胞分析仪检测嗜酸性粒细胞(Eos)的水平。比较支气管哮喘急性发作者和健康对照者外周血中上述各指标的水平以及它们之间的相互关系,并研究它们与支气管哮喘急性发作期严重程度之间的关系。结果 (1)支气管哮喘急性发作者血清中IL-33、sST2、IgE、Eos(%)的水平明显高于健康对照者(P<0.05)。(2)支气管哮喘急性发作者外周血中IL-33、sST2的水平与IgE和Eos之间两两呈正相关性(P<0.05)。(3)支气管哮喘急性发作者血清中IL-33与sST2之间呈正相关性(P<0.05)。(4)支气管哮喘急性发作者血清中IL-33、sST2的水平与疾病的严重程度之间无相关性(P>0.05)。结论 (1)IL-33、sST2在支气管哮喘急性发作者血清中升高;(2)IL-33及sST2可作为支气管哮喘炎症检测的指标。
