Study Group
The study cohort included patients younger than 18 years, reported between July 2007 and March 2018, with moderate and severe anaphylaxis triggered by food (Figure 1). For comparison analysis was performed on the peanut anaphylaxis subgroup versus the subgroup of anaphylaxis triggered by other food.
Only cases fulfilling the modified National Institute of Allergy and Infectious Diseases/Food Allergy and Anaphylaxis Network (NIAID/FAAN) diagnostic criteria for anaphylaxis were included. The severity of reaction was graded according to the Ring&Messmer classification (grade II-IV). Peanut as an elicitor was ascertained by the local allergy specialist based on in-depth diagnosis.
