Alergia a fórmulas de sustitución en alérgicos a proteínas de leche de vaca

The use of wide hydrolyzated cow's milk proteins or soy formulae in cow's milk proteins allergy treatment is necessary. Occasionally, these formulas could not be tolerated by very sensitized patients, without any prediction of this intolerance by clinical or analytical data. Due to this situation, a controlled tolerance test is recommended before the beginning of treatment. Soy formulas could be good substitutes of hydrolyzated formulae in IgE-mediated cow's milk allergy, when these are not tolerated and the child is older than six months and does not show digestive signs. Sensitization to soy protein is not very frequent in infants and, when it happens, usually does not have any clinical manifestation.
