Drug-induced anaphylaxis in children

Area of Science:

• Pediatrics
• Allergy and Immunology
• Pharmacology

Background:

• Anaphylaxis is a common pediatric emergency, with drug triggers increasing from infancy to adolescence.
• Compared to adults, drug-induced anaphylaxis is less frequent in children, potentially due to fewer comorbidities.
• Antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs) are primary culprits in pediatric drug-induced anaphylaxis.

Purpose of the Study:

• To review the epidemiology, triggers, mechanisms, and management of drug-induced anaphylaxis in children.
• To emphasize the importance of accurate diagnosis and appropriate work-up to prevent recurrent and unnecessary drug avoidance.

Main Methods:

• Literature review focusing on pediatric drug-induced anaphylaxis.
• Analysis of immune-mediated (IgE, IgG) and non-immune-mediated mechanisms.
• Discussion of diagnostic and therapeutic strategies.

Main Results:

• Antibiotics and NSAIDs are the most frequent drug triggers in children.
• Both IgE-mediated and non-immune-mediated pathways are implicated.
• Mortality is rare in children, possibly due to a lower incidence of comorbidities.

Conclusions:

• Accurate diagnosis and prompt management are essential for pediatric drug-induced anaphylaxis.
• Proper evaluation helps prevent severe re-exposures and avoids unnecessary avoidance of safe medications.
