IGHE and allergic disease: The cumulative incidence of sensitization as measured by serum antigen-specific IgE against egg white and cow's milk or in a skin prick test against egg, milk, cat, birch, or timothy tended to be lower in the probiotic group (18% vs 29%); when infants with maternal allergy were compared, the difference was significant (14% vs 31%, P = 0.02).
