哮喘并过敏性鼻炎儿童血清总IgE、外周血嗜酸性粒细胞、过敏原致敏程度与呼出气一氧化氮间的关系

摘要

Objective To analyze the correlation among serum total IgE(TIgE),blood eosinophil(EOS) counts,the degree of sensitization for skin prick test(SPT),and fractional exhaled nitric oxide(FeNO)in chil-dren with asthma and allergic rhinitis. Methods We collected 121 children with asthma and allergic rhinitis andtheir serum TIgE,blood EOS,FeNO,and SPT for 14 common allergens. Results There were 75.2%patients sensitizing to at least two allergens.TIgE levels in poly-sensitized subjects were higher than that of mono-sensitized subjects(P < 0.05)The number of SPT sensitized allergens was positively correlated with the TIgE levels(P <0.05)FeNO levels were correlated with TIgE levels and EOS percentage(P < 0.05). TIgE levels in subjects with class 2 or 3 in SPT for house dust mite increased significantly ,compared with class 0 or 1. Conclusion There were some correlations among the four detections ,providing important reference for clinical diagnosis and treatment of respiratory allergic disease%目的 分析哮喘合并过敏性鼻炎儿童血清总IgE(total IgE,TIgE)、外周血嗜酸性粒细胞(EOS)、皮肤点刺试验(SPT)致敏程度与呼出气一氧化氮(FeNO)之间的相关性.方法 收集哮喘合并过敏性鼻炎的儿童121例,分别进行血清TIgE、外周血EOS和FeNO检测,以及14种常见过敏原的皮肤点刺试验.结果 75.2%的患儿对2种或以上过敏原致敏.多过敏原致敏的患儿TIgE水平比单致敏的患儿高(P<0.05).TIgE水平与SPT致敏过敏原数量呈正相关(P<0.05);FeNO水平与TIgE水平和EOS%也有一定的相关性(P<0.05).屋尘螨SPT结果为2或3级时,其TIgE水平相对0或1级显著增高(P<0.05).结论 SPT过敏原致敏程度、血清TIgE、外周血EOS和FeNO之间相互联系、相互补充,可以为呼吸道过敏性疾病的临床诊治提供重要的参考.
