- Allergic proctocolitis: benign disorder of blood streaked stools in otherwise healthy-appearing infants
- Occurs in infants and children related to food, particularly cow's milk in infants and soy or eggs in older children
- Both IgE and non-IgE related mechanisms (Allergol Immunopathol (Madr) 2009;37:36)
- Some clinical cases of food allergy in young children are eventually diagnosed as inflammatory bowel disease (Med Wieku Rozwoj 2006;10:475)
- Italian study of allergic proctocolitis: atopy patch tests positive in 100% infants, multiple positivity in 50%; sensitization for breast milk in 100%, cow's milk in 50%; also soy (28%), egg (21%), rice (14%), wheat (7%) (BMC Gastroenterol 2011;11:82)
- Removal of cow's milk from infant or (if breast fed) motherís diet
- Elemental diet based on amino acid formula typically resolves symptoms in 2-3 days, GI eosinophilic inflammation within 6 weeks (Pediatr Allergy Immunol 2007;18:360)
