REVIEW ER 'S CONCLUSIONS There is no evidence to support feeding with a hydrolysed formula for the prevention of allergy in preference to exclusive breast feeding .
In high risk infants who are unable to be completely breast fed , there is evidence that prolonged feeding with a hydrolysed compared to a cow 's milk formula reduces infant and childhood allergy and infant CMA .
BACKGROUND Allergies and food reactions are common and may be associated with foods including adapted cow 's milk formulas .
Formulas containing hydrolysed proteins have been used to treat infants with allergy or food intolerance , and have been advocated for prevention of allergy and food intolerance in infants .
OBJECTIVES To determine whether use of hydrolysed formulas for infant feeding prevents allergy and food intolerance .
If hydrolysed formulas are effective , to determine what type of hydrolysed formula is most effective including extensively and partially hydrolysed formulas .
To determine which infants benefit including infants at low or high risk of allergy and infants receiving early , short term or prolonged formula feeding .
Soluble Adhesion Molecules and Oral Antigen Feeding in Infants
Oral administration of foreign proteins , e.g. cow 's milk ( CM ) proteins , stimulates the immune system and induces humoral and cellular immune response against these antigens in infants . Up-regulation of adhesion molecules is known to be associated with activation of the immune system . The purpose of the study was to examine whether orally administered CM proteins induce elevation in soluble adhesion molecules , i.e. intercellular adhesion molecule-1 ( ICAM-1 ) and L-selectin , in infants . In a double-blind trial , 10 infants received CM-based formula and 10 infants casein hydrolysate formula until the age of 9 mo . The infants of mothers with insulin-dependent diabetes mellitus ( IDDM ) were recruited into a pilot study of a trial for primary prevention of IDDM by elimination of CM proteins from the diet during early infancy . A cord blood sample and peripheral blood sample s were taken at the ages of 3 , 6 , 9 , and 12 mo of age . The levels of soluble ICAM-1 and L-selectin were measured by ELISA . The levels of soluble ICAM-1 were higher at the ages of 3 , 6 , 9 , and 12 mo in infants who received CM-based formula than in infants who received hydrolyzed formula ( p = 0.05 ) . Instead , no difference was found in the the levels of soluble L-selectin . The levels of soluble ICAM-1 and L-selectin were higher in all infants when compared with the levels reported in adults or to the levels seen in cord blood . Orally fed CM proteins induce an elevation in soluble ICAM-1 in infants . This may reflect the generation of an immune response against these proteins , because ICAM-1 has an important costimulatory role in lymphocyte activation
