(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. ER -
