[Clinical research of specific IgE and IgG4 antibody in allergic children. Examination by multiple factor analysis-type II. (objective variables: specific IgE antibodies and IgG4 antibodies to food allergen)].

We examined the influence power of 16 explanation variables to specific IgE antibody and IgG4 antibody to egg white cow's milk, and soybean in 150 asthmatic children by Multiple Factor Analysis-Type II 16 examination variables; 1) sex, 2) age, 3) onset age, 4) IgE RIST, 5) eosinophile count, 6) IgE RAST score to house dust, 7) IgE RAST score to Dermatophagoids farinae, 8) atopic dermatitis, 9) allergic rhinitis, 10) family history of allergy, 11) positive counts of food allergen: IgG4, 12) specific IgG4 antibody to cow's milk, 13) specific IgG4 antibody to soybean, 14) exercise induced asthma, 15) severity of asthma. The following results were obtained. 1) To introduce range relative ratio, we were able to use all 16 explanation variables on the occation of calculating by Multiple Factor Analysis-Type II. 2) 4 explanation variables (specific IgG4 antibody to soybean, IgE RIST, IgE RAST score to Dermatophgoides farinae, age) had the stronger influence power to 8 objective variables than the other explanation variables. 3) Only 2 explanation variables (specific IgE antibody to soybean, family history of allergy) had the stronger influence power to 8 objective variables than the other explanation variables.
