Case History - Section 1

An adverse reaction to food is best referred to as food hypersensitivity. However, when immunological mechanisms have been demonstrated the appropriate term is food allergy.

When the role of IgE has been demonstrated, the term is IgE-mediated food allergy.

This case history focuses on IgE-mediated food allergy from infancy to 16 years of age.

James is now 16 years old.

He first presented at 8 months with severe atopic eczema (atopic dermatitis).

James was born full term and was breast fed exclusively for 6 months.

Atopic eczema commenced at 6 weeks and became generalized and severe. He was a colicky, unsettled baby.

Solids were introduced at 6 months beginning with rice cereal with some cow's milk formula. His atopic eczema worsened significantly at this stage.



Q2. What investigations could be performed at this stage?

Select the answer that is correct:

  1. Skin prick test and/or allergen specific IgE in serum

  2. Allergen challenge

  3. Atopy Patch Test (APT)

  4. Histamine Release test (HR test)
