We found no evidence to support short-term or prolonged feeding with a hydrolysed formula compared with exclusive breast feeding for prevention of allergic disease .
Very low- quality evidence indicates that short-term use of an EHF compared with a CMF may prevent infant CMA .
Further trials are recommended before implementation of this practice .We found no evidence to support prolonged feeding with a hydrolysed formula compared with a CMF for prevention of allergic disease in infants unable to be exclusively breast fed
BACKGROUND Infant formulas containing hydrolysed proteins have been widely advocated for preventing allergic disease in infants , in place of st and ard cow 's milk formula ( CMF ) .
However , it is unclear whether the clinical trial evidence supports this .
OBJECTIVES To compare effects on allergic disease when infants are fed a hydrolysed formula versus CMF or human breast milk .
If hydrolysed formulas are effective , to determine what type of hydrolysed formula is most effective , including extensively or partially hydrolysed formula ( EHF/PHF ) .
To determine whether infants at low or high risk of allergic disease , and whether infants receiving early short-term ( first few days after birth ) or prolonged formula feeding benefit from hydrolysed formulas .
Does Early Diet Have an Effect on Subsequent Macromolecular Absorption and Serum IgE?
A group of 130 healthy term infants were r and omly assigned at birth to one of three feeding regimens for the first 3 days of life : human milk ( HM ) , cow-milk formula ( CMF ) , or a casein hydrolysate formula ( CHF ) . The formula-fed infants received no human milk during the study days . After day 3 , all infants were exclusively breast-fed . Blood sample s were taken at 4 days and at 2 and 4 months of age during outpatient visits . Macromolecular absorption was analyzed 60 min after a feed of human milk by measuring the serum α-lactalbumin ( S-αLA ) concentrations by a competitive radioimmunoassay . Total serum IgE ( S-lgE ) was assayed by radioimmu-noassay . The median S-IgE value was significantly lower at 2 months of age in the CHF group than in the HM group . The values remained significantly lower , even at 4 months of age , in the CHF group than in either the HM or the CMF group . The median S-αLA concentration at 2 months of age was significantly higher in the CHF group than in either the HM group or the CMF group . No significant differences could be found between the CMF and HM groups at any time . One infant in the HM group and one infant in the CMF group developed infantile colic . Two infants in the CHF group developed symptoms of cow-milk allergy . All other infants were healthy at 4 months of age
