Colic and the effect of changing formulas: a double-blind, multiple-crossover study.
This study investigated the effect of changing the formulas of colicky infants and addressed the method ologic flaws of earlier studies . Attention was paid to issues of design ing a blind study , providing a washout period , and measuring and reproducing the effect . In this r and omized , double-blind trial , three changes of formula were made : for each of four 4-day periods , colicky infants alternately received a casein hydrolysate formula ( Nutramigen ) and a formula containing cow milk . Mothers recorded crying in diaries and indicated which crying episodes they considered to have been caused by colic . Nine infants were started on Nutramigen and eight on the cow milk formula .  With the first formula change there was significantly less crying and colic in infants when they were fed Nutramigen than when they were fed cow milk ( p less than 0.01 ) ; with the second change there was less colic when infants were fed Nutramigen ( p less than 0.05 ) but not significantly less crying . By the third change there were no significant differences between formulas . Further analyses demonstrated that there were more clinical ly meaningful positive responses ( a change in crying by at least one third ) to Nutramigen than to cow milk ( p less than 0.05 ) . However , only one subject had a clinical ly meaningful response in colic to all three formula changes . These results demonstrate that in some instances , colic improves with elimination of cow milk formula . However , the effect diminishes with time , and only infrequently is the effect reproducible
