Incidence, etiology, and recurrence of anaphylaxis

In this population-based retrospective analysis, researchers found that anaphylaxis was relatively uncommon (incidence 50 per 100,000 person-years), was not morbid (resulted in no deaths), and was most commonly caused by foods (33%), followed by insect stings (19%), and medications (14%). The trigger was unknown in 25%. A second recurrence occurred in 21%, and a third recurrence in 5%. This study can help us educate our patients presenting with anaphylaxis (abstract)
