Key clinical point: Children with atopic dermatitis (AD) may have a higher sensitivity to contact allergens, such as fragrances and metals, than children without AD.
Major finding: Overall, 36.9% vs 26.4% of children with vs without AD presented with at least one positive patch test. Children with v. without AD showed a higher prevalence of ≥1 positive patch test for allergens, such as nickel sulfate, cobalt chloride, methylisothiazolinone, fragrance mix-2, potassium dichromate, fragrance mix-1, methylchloroisothiazolinone/methylisothiazolinone, and neomycin sulfate, with the prevalence difference being highest for fragrance mix-1 (5.8% vs 0.9%; P = .004293).
Study details: This retrospective study included 432 children aged 0-14 years with eczematous dermatitis who underwent patch testing, of which 23.8% of children were diagnosed with AD.
