Insights

Pediatric hand eczema (HE) has distinct allergens, with nickel and methylisothiazolinone being common. Patch testing reveals similar positive rates in children with and without HE.

Area of Science:

  • Dermatology
  • Allergology
  • Pediatrics

Background:

  • Etiologies and relevant allergens for pediatric hand eczema (HE) are not well understood.
  • Characterizing these factors is crucial for effective diagnosis and management in children.

Purpose of the Study:

  • To identify the causes and common allergens in children and adolescents under 18 with hand eczema.
  • To determine the prevalence of positive and currently relevant allergens in this pediatric population.

Main Methods:

  • Retrospective analysis of North American Contact Dermatitis Group data from 2000-2016.
  • Inclusion of 1634 pediatric patients, with a focus on the 237 diagnosed with hand eczema.
  • Utilized multivariable logistic regression to identify associations and relevant allergens.

Main Results:

  • Allergic contact dermatitis (49.4%), atopic dermatitis (37.1%), and irritant contact dermatitis (16.9%) were key diagnoses in pediatric HE.
  • Children with HE showed similar positive patch test rates (56.1%) compared to those without (61.7%).
  • Top relevant allergens included nickel, methylisothiazolinone, propylene glycol, decyl glucoside, and lanolin, with HE associated with specific allergens like lanolin and quaternium-15.

Conclusions:

  • Pediatric patients with hand eczema referred for patch testing exhibit a high rate of positive results, comparable to controls.
  • A distinct, relatively narrow profile of currently relevant allergens was identified in children with hand eczema.
