Abstract Clinical experience ("the dangerous bottle") and experimental evidence indicate that the early life of an infant is particularly important for the development of the immune responses to food antigens. However, the clinical and immunologic consequences of a brief exposure to, or avoidance of, food antigens during the neonatal period in human infants are poorly understood and documented. We present the preliminary results of a prospective controlled study of 256 normal breast-fed infants randomly assigned to receive (blind) either an adapted formula (Nidina) or a partially hydrolyzed formula (Nidal HA) as a supplement to breast-feeding for a few days when necessary, and to be examined at days 5, 90, 150, and 365. The results indicated that (1) the prevalence of clinical symptoms and of total and specific IgE responses was not statistically different in the two groups of infants and (2) infants fed a hydrolyzed formula had median titers of specific IgG lower than those fed an adapted formula; the difference was significant for alpha-lactalbumin at day 90 (p < 0.005) and for alpha-lactalbumin (p < 0.05), casein (p < 0.05), and hydrolyzed formula (p < 0.01) at day 150. Humoral immune responses of breast-fed infants to food antigens thus appear to be modulated by early, short-term exposure to them.
