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 .
Hypoallergenicity and efficacy of an amino acid-based formula in children with cow's milk and multiple food hypersensitivities.
OBJECTIVE To determine the hypoallergenicity and efficacy of a pediatric amino acid-based formula ( AAF ) , EleCare , for children with cow 's milk allergy ( CMA ) and multiple food allergies ( MFA ) . STUDY DESIGN Hypoallergenicity was determined by performing blinded oral food challenges in 31 consecutive children with documented CMA .  Growth , tolerance , and biochemical response were evaluated during a nonr and omized feeding study with each child serving as his or her own control . RESULTS Thirty-one children ( median age , 23.3 months ; range , 6 months to 17.5 years ) were recruited ; 29 had MFA , 17 had acute reactions and cow 's milk-specific IgE antibody , and 14 had allergic eosinophilic gastroenteritis . At study entry , 23 were receiving another AAF ;  13 had not tolerated extensively hydrolyzed formula .  Eighteen subjects with allergic eosinophilic gastroenteritis and /or MFA were followed up while receiving AAF for a median of 21 months ( range , 7 to 40 months ) , with biochemical analysis performed at 4 months . No statistically significant differences were observed in the change in weight or height National Center for Health Statistics z scores from entry ; the percent of expected growth exceeded 90 % . There was a small decline in percent eosinophils and increase in hemoglobin , hematocrit , and serum ferritin level ( P < .05 ) . Except for small increases in plasma leucine and valine levels ( P < or = .006 ) , the remaining biochemical markers were unchanged . CONCLUSIONS The AAF was hypoallergenic and effective in maintaining normal growth for children with CMA and MFA
