Some infants may develop a non-IgE-mediated hypersensitivity to various proteins in cow's milk.
Clinical features:
(1) infant being fed cow's milk
(2) failure to thrive
(3) gastrointestinal tract bleeding
(4) iron deficiency anemia
(5) recurrent episodes of pneumonia with pulmonary infiltrates and hemosiderosis
Laboratory findings:
(1) serum antibodies (precipitins) to cow milk proteins
(2) hemosiderin-laden macrophages in sputum
The diagnosis is supported if the findings resolve on elimination of cow's milk from the infant's diet.
Differential diagnosis:
(1) iron deficiency secondary to poor dietary intake ("milk baby", see 12.04)
