Area of Science:

Allergy and Immunology
Clinical Medicine
Food Science

Background:

Food allergies are a growing public health concern.
Pine nuts are a common ingredient in various cuisines.
Previous literature lacks documented cases of pine nut allergy.

Observation:

Two patients presented with allergic reactions following pine nut ingestion.
Clinical symptoms were consistent with allergic responses.
Skin prick testing with aqueous pine nut allergen yielded immediate positive reactions.

Findings:

The positive skin tests suggest an immunoglobulin E (IgE)-mediated allergic mechanism.
These findings represent the first reported instances of pine nut allergy.
The allergic reactions were specifically linked to pine nut consumption.

Implications:

This discovery highlights pine nuts as a potential food allergen.
Clinicians should consider pine nut allergy in patients with unexplained allergic reactions.
Further research is warranted to understand the prevalence and characteristics of pine nut allergy.
