title: Comparison of total IgE and anti-mite IgE antibody levels in the sera of patients with atopic dermatitis and/or atopic bronchial asthma.
abstract: In the present study characterization of serological features of AD and/or BA patients were attempted. Nearly all of the patients (23 out of 24) with AD with or without episodes of BA had total IgE levels higher than 1,000 IU/ml. Conversely, 14 out of the 15 BA patients showed total IgE levels less than 1,000IU/ml.9 out of the 14 AD patients with BA(AD + BA) had histories of childhood asthma but required no current treatment for BA. The rest of the AD + BA patients required medication for BA but they were easily controllable with conventional bronchodilators such as beta 2 stimulators and/or xanthine derivatives. It was shown that AD patients (n = 6) with extremely high titers of anti-mite IgE antibodies (more than 110 PRU/ml up to 820 PRU/ml) remained free from BA episodes in the presence of hyper IgE immunoglobulinemia (1,818 IU/ml to 47,300 IU/ml). The results indicated that hyper IgE immunoglobulinemia in atopic patients might prevent the development of severe BA, but on the other hand, increase the possibility of developing AD.
