Challenge-proven immediate type multiple local anesthetic hypersensitivity in a child

Area of Science:

• Allergy and Immunology
• Pediatric Dentistry
• Pharmacology

Background:

• Adverse reactions to local anesthetics (LA) are frequently observed in dental and minor surgical procedures.
• Most reported LA reactions are psychosomatic, vasovagal, or toxic, not immune-mediated.
• True immune-mediated reactions to LA are exceptionally rare, accounting for less than 1% of all adverse events.

Observation:

• Immune-mediated reactions to LA are predominantly documented in adult patients.
• This report focuses on a unique pediatric case involving hypersensitivity to LA.
• The patient exhibited sensitivity to two distinct amide-derivative LA agents.

Findings:

• Confirmed hypersensitivity to two different amide-derivative local anesthetics in a pediatric patient.
• This case represents an extremely rare instance of immune-mediated LA reaction in a child.
• The findings challenge the prevailing notion that immune-mediated LA reactions are exclusive to adults.

Implications:

• Highlights the potential for rare immune-mediated local anesthetic reactions in pediatric populations.
• Emphasizes the importance of considering hypersensitivity in children presenting with unusual reactions to LA.
• Suggests a need for increased vigilance and diagnostic consideration for rare allergic responses to local anesthetics in pediatric patients.
