Concepts de base
ACD is under-detected in children with AD, emphasizing the importance of considering ACD in patients with AD and referring more children for testing.
Résumé
The study highlights the prevalence of allergic contact dermatitis (ACD) among children with atopic dermatitis (AD). Key points include:
- Children with AD more likely to have positive patch test results for ACD.
- ACD often misdiagnosed as AD, emphasizing the need for patch testing.
- Top allergens identified in children with AD.
- Importance of patch testing in children with AD.
- Challenges in availability of patch testing and trained physicians.
Stats
Of 912 children referred for patch testing, those with AD were more likely to have more than one positive reaction (OR, 1.57; 95% CI, 1.14-2.14; P = .005).
Children with AD had a longer history of dermatitis (4.1 vs 1.6 years, P < .0001) prior to patch testing.
ACD to bacitracin (OR, 3.23; P = .030) and to cocamidopropyl betaine (OR, 3.69; P = .0007) was significantly more common in children with AD.
ACD to "carba mix" was significantly more common in children with AD than in those without (OR, 3.36; P = .025).
