Objective
This study aimed to identify the triggers of pediatric anaphylaxis in Spain and to analyze the circumstances of the episode.
Methods
Planned secondary analysis of a prospective observational multicenter study endorsed by the Spanish Society of Pediatric Emergencies including children aged younger than 18 years diagnosed with anaphylaxis in 7 Spanish pediatric emergency departments (EDs) between 2016 and 2018. We analyzed factors related to the anaphylaxis episode and its management.
Results
Four hundred fifty-three cases were registered, happening mainly at home (295 [65.1%]), school (65 [14.3%]), and street (61 [13.5%]). The median age was 5 years, 143 (31.6%) had previous episodes, and 165 (36.4%) had previously been prescribed an epinephrine autoinjector, used in 40 (24.2% of those prescribed). Two thirds were well-appearing when arriving to the pediatric ED. Food was the trigger in 396 (87.4%). In 349 with a single food involved, the most frequent were milk (108 [30.4%]), nuts (103 [29.0%]), hen's egg (40 [11.3%]), and fish (31 [8.7%]), with variations related to the age of the child.
Conclusions
Food, especially milk and nuts, are responsible for most anaphylaxis diagnosed in Spanish pediatric EDs. Consideration should be given to improving health education due to the low use of epinephrine autoinjectors.
