摘要 目的通者过对矽肺患者血清总IgE、吸人性过敏原(phadiatop)及嗜酸阳离子蛋白(ECP)含量的检测,了解矽肺患者机体的免疫状态。方法选择矽肺患者及接尘者共94例为暴露组,其中40例为观察对象组(O期),54例为确诊矽肺患者(I期25人、Ⅱ期14人、Ⅲ期15人);以健康体检者40人为健康对照组;患有其他肺部疾病(肺癌、肺炎及肺结节等)的患者113人为疾病对照组。测定血清中总IgE、吸人性过敏原及ECP含量。结果暴露组的IgE阳性、血清IgE和吸人性过敏原总阳性率明显高于健康对照组,差异有统计学意义(P〈0.05)。暴露组各期病例血清总IgE及吸人性过敏原水平的差异无统计学意义(P〉0.05)。暴露组血清总Ig和吸人性过敏原水平与其他肺部疾病组的差异无统计学意义(P〉0.05)。暴露组血清ECP含量为(16.56±6.71)μg/L,明显高于其他肺部疾病组[肺癌:(5.77±5.63)μg/L、肺炎:(6.18±4.40)μg/L、肺结节:(5.16±1.66)μg/L],差异有统计学意义(P〈0.05)。观察对象组血清ECP含量为(20.15±4.49)μg/L,明显高于各期病例[I期:(16.68±4.34)μg/L、11期:(7.38±1.89)μg/L、Ⅲ期:(4.83±1.21)μg/L],差异有统计学意义(P〈0.05)。I期尘肺病例血清ECP含量明显高于Ⅱ期和Ⅲ期,差异均有统计学意义(P〈0.05)。血清ECP水平与尘肺分期呈负相关关系,随尘肺期别的增加,血清ECP水平呈下降趋势(r=0.766,P〈O.05)。结论观察对象和I期尘肺患者血清中ECP水平明显增高,且随尘肺期别的增加,血清ECP含量呈下降趋势。
