Effectiveness of casein hydrolysate feedings in infants with colic

This study found that two casein hydrolysate formulas varying in composition were equally effective in managing colicky symptoms associated with protein sensitivity. Both hydrolysate formulas were associated with a significant, comparable reduction in crying duration and intensity from baseline in 15 of 22 infants with complete data. Subsequent challenge data suggest that the population studied were infants experiencing colicky symptoms due to protein sensitivity. A greater proportion of infants showed a positive reaction (> or = 1.5 h of crying/d) to the protein challenges than the placebo challenge, and crying was rated as more intense during whey and milk protein challenges.
