Systemic allergic reaction to pine nuts.

Author information

  • 1Frederiksberg Hospital, Pulmonary and Allergy Clinic, Denmark.


This case report describes a systemic reaction due to ingestion of pine nuts, confirmed by an open, oral provocation test. Skin prick testing with the aqueous allergen revealed an immediate positive prick test, and histamine release from basophil leukocytes to the aqueous allergen was demonstrated. Radioallergosorbent test demonstrated specific IgE antibodies to pine nuts. In a review of medical literature, we found no reports of either oral provocation tests confirming a systemic reaction due to ingestion of pine nuts or demonstration of specific IgE antibodies.
