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 .

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 .
Effect of allergen avoidance in infancy on allergic manifestations at age two years.
BACKGROUND One hundred twenty children , identified before birth as being at high risk for atopy , were prenatally assigned to prophylactic or control groups . METHODS The infants in the prophylactic group either received breast milk from mothers on an exclusion diet or an extensively hydrolyzed formula . Their bedrooms and living rooms were treated repeatedly with an acaricide , and they used polyvinyl-covered mattresses with vented head areas . The infants in the control group were fed conventionally , and no environmental control was recommended . RESULTS A significant advantage , first demonstrated at 1 year of age , persists for children in the prophylactic group . They have less of any allergy or eczema , but the reduced prevalence of asthma is no longer significant . Only three children in the prophylactic group had positive skin prick test results compared with 16 in the control group , suggesting a significant reduction in sensitization . CONCLUSION A dual approach to allergen avoidance , focusing on foods and aeroallergens , appears to be beneficial in selected high-risk infants . Avoidance of potent allergens in early life increases the threshold for sensitization in these high-risk infants . Whether sensitization has been avoided or merely deferred has yet to be proved
