IgE and IgG antibodies in children with food allergy.
The aim of the present study was to estimate the occurence of specific IgE and IgG to food in children with food allergy. In 48 children aged between 6 months and 3 years with food allergy symptoms and in 8 children of the same age without food allergy, specific IgE and IgG were determined using the immunoenzymatic Visagnost method. Among the children with food allergy, 22.9% had specific IgE to food, 62.5% had specific IgG and 14.6% had both specific IgE and IgG, while children without symptoms of food allergy had neither specific IgE nor IgG to food. During the first three years of life, the undesirable response to aliments is more often IgG--dependent than IgE--dependent. Specific IgG to milk, eggs and flour has been found two or three times more often than IgE.
