[The special problem of insect venom allergy in childhood]

Area of Science:

• Allergy and Immunology
• Pediatrics
• Toxicology

Context:

• Hymenoptera sting allergy management in children requires accurate risk assessment.
• Existing risk scores may overestimate the need for hyposensitization in pediatric populations.
• The natural history of hymenoptera sting allergy is generally less severe in children compared to adults.

Purpose:

• To evaluate the predictive accuracy of a commonly used risk score for hymenoptera sting allergy in children.
• To determine if the existing risk score accurately identifies children requiring hyposensitization.
• To develop an improved diagnostic scheme for identifying children who truly need hyposensitization for hymenoptera sting allergy.

Summary:

• A risk score, assessing allergic reaction, sensitization (skin prick test, specific IgE), and specific IgG, was evaluated in 93 children with low scores (<7 points) and 119 children with high scores (>6 points).
• Children with low scores had a 96% absence of severe systemic reactions upon field stings.
• Among children with high scores receiving rush hyposensitization, only 32% developed systemic reactions, indicating the score overestimates treatment necessity.

Impact:

• The study highlights that the evaluated risk score appropriately identifies children unlikely to require hyposensitization.
• The findings suggest the need for a refined diagnostic strategy, including challenge stings, to avoid unnecessary treatments in children.
• This research contributes to optimizing the management of hymenoptera sting allergy in pediatric patients, potentially reducing overtreatment.
