[The study of allergic children under one-year old. The measurement of IgE and IgG4 antibody titers to egg white, milk and soybean].

We measured the IgE and IgG4 antibody titers to egg white, and soybean of 94 allergic children under one year. (21 wheezy children, 35 atopic dermatitis, 34 wheezy children with atopic dermatitis, and 4 other allergic children). The results were as follows; 1) The positive ratio of IgE antibody titers to egg white was higher than the other IgE antibody titers, and of IgG4 antibody titers to milk was higher than the other IgG4 antibody titers. 2) Of each allergic symptoms, the positive ratio of IgG4 antibody titers to milk was higher than the others in wheezy children group. And the positive ratio of IgE antibody titers to egg white and milk were higher than the others in atopic children and wheezy children with atopic dermatitis. 3) The positive ratio of IgE antibody titers to egg white and milk were higher than the others in the group showed IgE RIST more than 21 IU/ml, and then the positive ratio of IgE antibody titers to egg white, milk and soybean and IgG4 antibody titers to egg white were higher than the others in the group showed eosinophil counts more than 301/mm3.
