Approach to milk protein allergy in infants.
OBJECTIVE
To provide a practical, evidence-based approach to the diagnosis and management of milk protein allergy in infants.


METHODS
MEDLINE was searched from 1950 to March 2008 using the MeSH heading milk-hypersensitivity. Additional sources were derived from reviews found with the initial search strategy. Evidence was levels I, II, and III.


RESULTS
Milk protein allergy is a recognized problem in the first year of life; cow's milk protein allergy is the most common such allergy. Diagnosis is suspected on history alone, with laboratory evaluations playing a supporting role. Confirmation requires elimination and reintroduction of the suspected allergen. Management includes diet modification for nursing mothers and hydrolyzed formulas for formula-fed infants. Assessing the underlying immunopathology can aid in determining prognosis.


CONCLUSIONS
The therapeutic model presented allows rapid assessment of the presence of allergy, timely management, and surveillance for recurrence of symptoms. Breastfeeding can be continued with attentive diet modification by motivated mothers.
