[The evaluation of nonspecific immunoglobulin E in cord blood of newborns in relation to maternal cow's milk allergen intake during pregnancy].

The relationship between maternal cow's milk allergen intake and cord blood IgE levels in newborns was assessed. Pregnant women were allocated to three groups in regard to amounts of cow's milk intake during pregnancy: high-, low-dose and without any changes. The mean nonspecific cord blood IgE level, birth weight and length of the newborns were calculated in each of the groups. No statistical difference between amounts of the milk allergen intake by pregnant women and cord blood IgE levels was found. Maternal food-avoidance diets instituted in pregnancy significantly affected a decrease in infant birth weight (p < 0.05).
