Antibiotic oral provocation challenge in children.

Area of Science:

• Pediatric Allergy and Immunology
• Clinical Pharmacology
• Drug Safety

Background:

• Antibiotic allergy is a common concern in pediatrics.
• Accurate diagnosis is crucial to avoid unnecessary antibiotic avoidance.
• Drug provocation testing (DPT) is a key diagnostic tool.

Purpose of the Study:

• To evaluate the safety and outcomes of DPT in children with suspected antibiotic allergy.
• To determine the incidence of allergic or adverse reactions during DPT.
• To assess if children outgrow antibiotic allergies over time.

Main Methods:

• Retrospective data compilation from 2007-2018 for children undergoing DPT.
• Standardized questionnaires collected parental history on allergies, atopy, and family history.
• Analysis of reactions during initial and follow-up DPTs.

Main Results:

• Out of 1440 children, 6.4% (92) had a mild allergic reaction during DPT.
• Sixty-four children had a second DPT 1-2 years later.
• Only eleven children showed a positive or delayed reaction on the second DPT.

Conclusions:

• Immediate moderate or severe allergic reactions were excluded in all cases.
• Oral DPT is a safe procedure for evaluating suspected antibiotic allergies in children.
• Most children outgrow their adverse drug reactions (ADRs), supporting the utility of repeat DPTs.
