RT期刊文章SR电子T1总血清免疫球蛋白E与非过敏个子中的哮喘有关188bet官网地址r yr 2000 ul //www.qdcxjkg.com/content/16/4/609.abstract ab abstract ab升高的血清免疫球蛋白(Ig)E是Atopy的标志,并有助于哮喘和支气管高性分子性的哮喘和支气管高分子。相比之下,IgE在非过敏受试者中的重要性尚不清楚。本研究的目的是在没有临床过敏的情况下阐明IgE和哮喘的潜在关联。为此,评估了1,219例连续的肺实践患者。通过负皮肤刺测试,特异性史和特定IgE的史来定义非过敏患者,509名受试者(42%)是非过敏性的。其中,80名患者(16%)的总IgE水平升高(> 150 U X ML(-1))。将IgE> 150 U X ML(-1)的非过敏性受试者的哮喘患病率和严重程度与正常IgE水平的受试者进行了比较,并且在所有非过敏性受试者和哮喘患者中,肺功能参数与血清IgE相关。与正常IgE的非过敏受试者相比,IgE水平升高的非过敏性受试者中哮喘更为普遍(39%vs 14%; P <0.001)。一秒钟(FEV1)%预测的强迫呼气量的非过敏性哮喘患者的肺功能值较低(66+20%对83 +/- 17%; p <0.001),FEV1%强制生命力(FVC)(FVC)(70+//-14%对81 +/- 8%; p <0.001)和强迫中呼气流量(FEF25-75)(1.7 +/- 0.9 l x S(-1)对2.8 +/- 0.9+0.9 l x s(-1); p=0.002) in patients with high IgE compared to asthmatics with normal IgE, and were negatively correlated with log IgE levels in all nonallergic asthmatics. (FEVI % pred: r=-0.5, p<0.001; FEV1% FVC: r=-0.53, p<0.001; FEF25-75: r=-0.52, p<0.001). In the whole study population, multivariate analysis showed a greater than fivefold asthma risk for nonallergic individuals with serum IgE>150 U x mL(-1). These data support the role of IgE as risk factor for asthma independent of allergy, and they further challenge the definition of intrinsic asthma as "non-IgE mediated" entity.
