We have studied development of the levels of IgA cow's milk (CM) antibodies in the saliva, faeces and serum of 20 term and 20 preterm infants from birth to 8 months. All infants already had IgA in their saliva during the first week of life. The levels peaked at the age of one month, thereafter decreasing in both groups; from the age of three months levels remained stable. Term infants had higher levels than preterm infants, but no differences were found between breastfed and CM-fed infants. Breast-fed infants had higher levels of IgA in their faeces than did CM-fed infants; the IgA levels were similar in breast-fed term and preterm infants, being highest at birth, and decreasing thereafter. We also showed rising titers of serum IgA CM antibodies, with higher levels in infants regularly exposed to CM than in breast-fed infants. We sought associations between the magnitude of intestinal permeability to human alpha-lactalbumin (ALA) measured at the ages of 4-7 days and one month and the levels of IgG antibodies to CM, but no such relation was found.
