[Incidence and symptoms of cow's milk protein intolerance following acute gastroenteritis in young infants. Effect of a hypoallergenic diet].

In a prospective randomized study we investigated in 28 mainly bottle-fed infants younger than 60 days whether in acute gastroenteritis a hypoallergenic formula could prevent the development of cow's milk protein intolerance. Group 1 (14 infants) was fed with a formula adapted to human milk, Group 2 (14 infants) got a semi-elementary formula (Alfaré). After 3 months group II was exposed to cow's milk protein with a standardized challenge and the incidence of CMPI in both groups was calculated. All cases with the acute form of CMPI occurred in group II (5/12) whereas in group I only one infant suffered from the protracted mild form of the disease. Inspite of the relatively small number of probands we conclude from our results that in infants who are not totally breast-fed in the post-enteritic period feeding with a formula adapted to human milk is preferable to hypoallergenic semi-elementary preparations. An allergen free period of 3 months seems to induce symptoms of cow's milk intolerance, probably as a booster-effect to early sensibilisation.
