Question 1

Which immunoglobulin mediates IgE-mediated food allergic reactions in children?

Accepted Answer

IgE

Answer

IgE antibodies sensitize mast cells and basophils; upon re-exposure to the allergen, cross-linking of IgE triggers immediate hypersensitivity reactions.

Question 2

A 9-month-old exclusively breastfed infant presents with blood-streaked stools and no other symptoms. What is the most likely diagnosis?

Accepted Answer

Food protein-induced allergic proctocolitis (FPIAP)

Answer

FPIAP typically presents in healthy-appearing infants with isolated rectal bleeding, most often due to cow's milk or soy proteins transmitted through breast milk.

Question 3

Which dietary change is first-line management for a breastfeeding mother whose infant has been diagnosed with cow's milk protein allergy (CMPA)?

Accepted Answer

Eliminate all cow's milk and dairy products from the mother's diet

Answer

Maternal elimination of cow's milk protein is the first-line approach to managing CMPA in breastfed infants, allowing continued breastfeeding.

Question 4

What is the most common food allergen causing anaphylaxis in school-age children in the United States?

Question 5

A child diagnosed with non-IgE mediated food protein-induced enterocolitis syndrome (FPIES) most commonly reacts to which food?
