摘要： 目的:探讨婴幼儿呼吸道合胞病毒(RSV)毛细支气管炎急性期外周血嗜酸粒细胞增多对预测日后发生婴幼儿哮喘是否有意义。方法:检侧60例首次患RSV毛细支气管炎婴幼儿急性期外周血嗜酸粒细胞的绝对及相对计数，并在该组患者3周岁时进行电话随访，根据毛细支气管炎发病后有无反复发作喘息将成功随访的43例患儿分成2组:无喘息发作组和哮喘组，同时记录哮喘家族史。结果:哮喘组在RSV毛细支气管炎急性期嗜酸粒细胞数增多人数明显多于无喘息发作组, 毛细支气管炎急性期嗜酸粒细胞增多患儿发生婴儿哮喘的比率，与无嗜酸粒细胞增多者比较，差异有显著性意义(χ2= 8.23,P<0.05)。结论:RSV毛细支气管炎急性期嗜酸粒细胞增多日后易发生婴幼儿哮喘。

    Abstract: Objective: To determine whether eosinophilia at the time of acute RSV bronchiolitis could predict the presence of infant asthma. Methods: 60 cases with RSV bronchiolitis were examined for peripheral blood eosinophil counts in the acute phrase ......
