    Abstract:
    One hundred and twenty five cases of atopic children such as atopic dermatitis and bronchial asthma were orally provocated with rare hen egg every 20 minutes one by one upto the whole amount. In one week observation 75 cases showed any symptoms of allergy including eruption and exacerbation of atopic eczema in an immediate, late, and/or delayed responses. Frequency of positive egg white-induce IL-2 responsiveness test in patients with positive oral provocation was 90.7% (68 out of 75 cases; sensitivity). That of negative test in patients with negative provocation was 84.0% (42 out of 50 cases; specificity). In contrast, specificity of IgE RAST for egg white were 88.0% comparable to the value of antigen-specific IL-2 responsiveness (AIR) test, but the specificity was lower value (37.3%) for screening the etiological antigens as compared to that of AIR test. High frequency of positive egg white-induced IL-2 responsiveness test was observed over an immediate, late and delayed responses, while low frequency of positive IgE RAST for hen egg was observed largely in patients showing delayed but not immediate response. The results indicate that IgE RAST in this study reflects IgE-mediated immediate type hypersensitivity, whereas AIR test reflects, in addition to immediate responses, late and delayed type hypersensitivity. The combined results suggest that AIR test in hen egg allergy is a useful method in vitro for both screening and determining etiological allergens, and might be able to substitute for provocation test in vivo for which many times, labours, expenses, and patients' risks are required, and to cover IgE RAST which fails to determine etiological allergens in 62.7% of patients with positive oral provocation.
