Direct Oral Challenges in Private Practice Setting to Delabeling Children With Beta-lactam Allergy

Overview

The purpose of this study is to demonstrate the feasibility of direct oral challenge performed in private practice setting for children with suspected benign delayed allergy to beta-lactams. The results of this study could help establish recommendations for conducting direct oral challenge in primary care settings to delabeling children with benign delayed reactions to beta-lactams.

Approximately 10% of children are labeled as allergic to beta-lactams (BL). Consequently, they receive alternative antibiotics with a broader spectrum but lower efficacy, leading to increased infectious morbidity and mortality, a higher risk of colonization with antibiotic-resistant bacteria, and elevated healthcare costs. However, true BL allergy is only confirmed in 5-10% of cases. Therefore, an essential challenge is to promptly identify non-allergic children to prevent unnecessary medical restrictions. The most common reactions are delayed and benign. Current guidelines recommend evaluating these reactions through direct oral challenge (DOC) without prior allergological assessment, as traditional diagnostic methods, particularly skin tests, have poor sensitivity in this context. However, the optimal setting for conducting these tests remains debated, particularly regarding whether they can be initiated in hospital settings or private medical practices. To date, over 8,300 DOCs have been performed in children, predominantly in hospital-based consultations. These tests have demonstrated a favorable safety profile, with positive DOC reactions often being of the same nature and less severe than the initial reported reaction. While many physicians perform DOCs in private practice, data on their use in pediatric populations remain scarce. The primary objective of this study is to assess the feasibility of DOCs conducted in private medical practices for children with suspected benign delayed allergy to BL
