title: How to prevent allergic disease. I. Study of specific IgE, IgG, and IgG4 antibodies in serum of pregnant mothers, cord blood, and infants.
abstract: We have investigated methods for decreasing the number of allergic patients and have produced the following data. We compared mothers' total IgE levels and allergen-specific IgG and IgG4 levels in 72 paired cases. In mothers with high total IgE, the cord blood levels of IgG and IgG4 specific for egg, milk, and mite allergens were significantly higher than in mothers with low IgE levels. Mothers who took over 200 ml of milk per day showed a statistically higher level of milk-specific IgG antibody. From our studies of IgE, IgG, and IgG4 antibody levels in atopic dermatitis patients, we conclude that specific IgG and IgG4 levels should be considered when eliminating offending foods. Infants with high egg-specific IgG antibody levels in cord blood were statistically more prone to develop allergic disease.
