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 .
Development of immune response to cow's milk proteins in infants receiving cow's milk or hydrolyzed formula.
BACKGROUND Development of humoral and cellular immune responses to orally administered antigens in human beings is poorly understood , although antigen administration has been suggested as a treatment for hypersensitivity disorders and autoimmune diseases . OBJECTIVE The purpose of the study was to investigate the development of systemic immune response in infants fed with formula containing whole cow 's milk proteins or hydrolyzed formula containing casein peptides .  METHODS In a double-blind trial , 10 infants received cow 's milk-based formula , and 10 infants received a casein hydrolysate formula until the age of 9 months . Blood sample s were taken at the ages of 6 , 9 , and 12 months . Cellular responses were assessed by proliferation assay of peripheral blood mononuclear cells to cow 's milk proteins ( beta-lactoglobulin , bovine serum albumin , and alpha-casein ) . Humoral responses to the same proteins were measured by ELISA for IgG antibodies . RESULTS Feeding infants with cow 's milk-based formula induced systemic humoral and cellular responses to cow 's milk proteins . T-cell response later declined , supporting the concept of oral tolerization . Exposure to cow 's milk proteins after the age of 9 months result ed in depressed cellular and humoral responsiveness to these proteins . CONCLUSION Our results support the view that induction of oral tolerance in human beings is an age-dependent phenomenon
