Insights
Food allergies are the leading cause of anaphylaxis in Korean children. Triggers vary by age, with milk common in younger children and seafood in older ones.
Area of Science:
- Pediatric Allergy
- Immunology
- Public Health
Background:
- Anaphylaxis is a severe, life-threatening allergic reaction.
- Understanding anaphylaxis triggers is crucial for prevention and management.
- Limited data exist on age-specific anaphylaxis triggers in pediatric populations.
Purpose of the Study:
- To identify and analyze anaphylaxis triggers in Korean children.
- To investigate age-specific patterns in anaphylaxis causation.
Main Methods:
- Retrospective review of medical records for pediatric anaphylaxis cases.
- Data collected from 23 secondary or tertiary hospitals in South Korea (2009-2013).
- Analysis of anaphylaxis triggers based on patient age.
Main Results:
- Food was the most frequent trigger (74.7%), followed by drugs/radiocontrast media (10.7%).
- Milk was the most common food allergen in younger children; seafood in older children.
- Drug-induced anaphylaxis increased with age, with antibiotics being a primary cause.
Conclusions:
- Food is the predominant anaphylaxis trigger in Korean children.
- Anaphylaxis triggers demonstrate significant variation across different age groups.
- Age-specific data are essential for targeted anaphylaxis prevention strategies.
Purpose:
Although anaphylaxis is recognized as an important, life-threatening condition, data are limited regarding its triggers in different age groups. We aimed to identify anaphylaxis triggers by age in Korean children.
Methods:
We performed a retrospective review of medical records for children diagnosed with anaphylaxis between 2009 and 2013 in 23 secondary or tertiary hospitals in South Korea.
Results:
A total of 991 cases (mean age=5.89±5.24) were reported, with 63.9% involving patients younger than 6 years of age and 66% involving male children. Food was the most common anaphylaxis trigger (74.7%), followed by drugs and radiocontrast media (10.7%), idiopathic factors (9.2%), and exercise (3.6%). The most common food allergen was milk (28.4%), followed by egg white (13.6%), walnut (8.0%), wheat (7.2%), buckwheat (6.5%), and peanut (6.2%). Milk and seafood were the most common anaphylaxis triggers in young and older children, respectively. Drug-triggered anaphylaxis was observed more frequently with increasing age, with antibiotics (34.9%) and nonsteroidal anti-inflammatory drugs (17.9%) being the most common causes.
Conclusions:
The most common anaphylaxis trigger in Korean children was food. Data on these triggers show that their relative frequency may vary by age.
