Incidence of IgE-Mediated Cow's Milk Allergy in Pediatric Patients with a History of Cow's Milk Protein-Induced Proctocolitis

Abstract

RATIONALE: In children with cow's milk protein-induced proctocolitis (CMPIP), prick skin test (PST) and cow's milk specific IgE (cm-IgE) are sometimes obtained before reintroduction of cow's milk to evaluate for IgE-mediated hypersensitivity. We aim to determine if these children are at increased risk of developing IgE-mediated hypersensitivity to cow's milk and describe the correlation between PST, cm-IgE, other food allergies, personal history, and family history of atopic disease with CMPIP.
