BACKGROUND: Anaphylaxis is a life-threatening allergic reaction with rising incidence worldwide. Young children's limited ability to express symptoms adds unique diagnostic challenges.
OBJECTIVE: To study on anaphylaxis in children, including triggers, symptoms, treatment, atopic status impact, and adrenaline injection time intervals.
METHODS: In-patient medical records of children who were diagnosed with anaphylaxis during 2014-2021 were reviewed.
RESULTS: One hundred thirty-three anaphylaxis events were identified. Food (47%) was the most common trigger, followed by drugs (31%), blood components (17%), insects (3%), and idiopathic causes (2%). Ten cases of refractory anaphylaxis, 2 cases of biphasic reactions, and 1 case of persistent anaphylaxis were found. There were no reported fatalities. The most common presentations involved the skin (94%), followed by the respiratory (73%), gastrointestinal (47%), and cardiovascular (42%) systems. In atopic patients, wheezing was more prominent than in those without atopy (p-value = 0.017). In the non-atopic patients, there was a higher incidence of cardiovascular symptoms, particularly hypotension (p-value = 0.001), compared to individuals with atopy. Children under 5 years old with mild-moderate anaphylaxis required more time to reach the hospital (147.0 vs. 45.0 minutes, p = 0.033) and to receive adrenaline injections (35.0 vs. 9.0 minutes, p-value = 0.017) than those with severe anaphylaxis.
CONCLUSION: Childhood anaphylaxis is prevalent. Children with mild-moderate anaphylaxis experienced delays in hospital visits and adrenaline administration. Education on allergies is needed to improve the identification and prompt response to anaphylactic reactions, especially in young children.
