Asthma is one of the major causes of death in otherwise healthy young individuals. However, many of these deaths may have been prevented by more aggressive treatment. To determine factors correlated with a high risk of death in Taiwanese children with atopic asthma. Taiwanese children aged 5-18 years, diagnosed with atopic asthma were enrolled in the study. Atopic asthma was diagnosed and immunoglobulin E (IgE) specific to antigens from any 1 of 8 allergens was measured (i.e. Dermatophagoides pteronyssinus, Dermatophagoides farinae, cat and dog dander, cockroach, egg white, milk and fish). High-risk asthma was defined as asthma requiring admission to a hospital or a visit to an emergency department. The study tried to determine the association of high-risk asthma with allergy-related parameters (e.g. asthma severity, asthma score, total serum IgE levels, serum levels of allergen-specific IgE, eosinophil count) and pulmonary function in Taiwanese children. One thousand one hundred and twenty-two Taiwanese children were evaluated. Those with higher asthma severity, asthma symptom score, serum levels of IgE specific to D. pteronyssinus and D. farinae, higher total serum IgE levels, and lower FEF25-75% (forced expiratory flow, 25-75%) values were considered to be members of the high-risk asthma group. The characterization of risk factors has enabled us to identify high-risk asthma in Taiwanese children, which will facilitate the treatment of these children in the future.
