Tree Nut Allergy Diagnosis Poses Challenges

Data presented here at the American College of Allergy, Asthma and Immunology Annual Scientific Meeting indicate that tree nut allergies are responsible for up to 40% of anaphylaxis reactions. Also, when combined with peanuts, tree nut allergies account for up to 90% of anaphylactic fatalities.

Healio has previously reported that despite exhibiting skin or blood test sensitivity to peanuts and tree nuts, more than 50% of patients with a documented allergy to an individual nut passed oral food challenges consisting of additional nuts.

That data, coupled with a discussion held by Maria Crain, APRN, CPNP-PC, AE-C, a pediatric nurse practitioner at the Food Allergy Center within Children’s Health in Dallas, and Jodi Shroba, MSN, APRN, CPNP, of the division of allergy and immunology at Children’s Mercy Hospital in Kansas City, Missouri, suggest tree nut allergy diagnosis is not always cut and dry.
