Insights
Antibiotic allergy, especially beta-lactam allergy, is often overdiagnosed in children. Current diagnostic approaches are shifting towards challenge-based methods, but more research is needed to confirm safety and efficacy.
Area of Science:
- Pediatric Allergy and Immunology
- Pharmacovigilance
- Clinical Pharmacology
Background:
- Adverse drug reactions in children are a significant concern, with a growing focus on antibiotic allergies.
- Mislabeling children with antibiotic allergy, particularly beta-lactam allergy, has recognized adverse health and economic consequences.
- Accurate diagnosis of antibiotic allergy is crucial due to the negative impacts of misdiagnosis.
Purpose of the Study:
- To review the prevalence, diagnosis, and management of antibiotic allergies in children.
- To highlight the common classes of antibiotics implicated in pediatric allergic reactions: beta-lactams, macrolides, and sulfonamides.
- To discuss the evolving diagnostic paradigms for antibiotic allergy in pediatric populations.
Main Methods:
- This article presents a narrative review of existing literature on pediatric antibiotic allergies.
- It synthesizes information on the prevalence, diagnostic strategies, and management approaches.
- The review focuses on beta-lactams, macrolides, and sulfonamides as primary antibiotic classes of concern.
Main Results:
- Antibiotic allergy is frequently overreported and inadequately diagnosed in pediatric patients.
- The prevalence of true antibiotic allergy is often lower than suspected.
- A shift in diagnostic practice towards challenge-based testing is emerging in pediatrics.
Conclusions:
- Overdiagnosis of antibiotic allergy in children leads to suboptimal treatment and potential adverse outcomes.
- The current diagnostic approach is transitioning, with a move towards challenge-only strategies in pediatric cases.
- Further large-scale studies are required to validate the safety and effectiveness of new diagnostic guidelines for antibiotic allergy in children.
Abstract:
Within the broad category of adverse drug reactions in children, there has been a recent focus specifically on the evaluation of children with antibiotic allergy, in particular, beta-lactam allergy. The potential consequences of being labeled beta-lactam allergy are increasingly recognized. Appropriate evaluation of children with suspected reactions to antibiotics is essential as it is increasingly being recognized that the label of "penicillin allergy" is associated with adverse health and economic outcomes. This review will focus on the 3 main classes of antibiotics reported to cause allergic reactions in children: beta lactams (penicillin derivatives and cephalosporins), macrolides, and sulfonamides. This article is a narrative review of the prevalence, diagnosis, and management of different types of antibiotic allergies in children. Our review reveals that antibiotic allergy is often overreported and not appropriately diagnosed in the pediatric age groups. There is a recent shift in the diagnostic paradigm from the use of skin tests and if negative challenges to the use of challenge only in the pediatric age group. Larger studies to establish the usefulness and safety of this new approach as well as updated guidelines are needed.
