Depressed neutrophil chemotaxis in infants with cow's milk and/or soy protein intolerance.

Neutrophil chemotaxis and random migration were studied in 11 infants with active cow's milk and/or soy protein intolerance and in an additional four infants following clinical recovery. Results were compared to 15 age-matched control subjects. Infants with active intolerance exhibited depressed chemotaxis and enhanced random migration. The four recovered infants had values similar to those of control subjects.
