Key clinical point: Allergic contact dermatitis (ACD) is an important comorbidity in patients with atopic dermatitis (AD) and leads to the maintenance and aggravation of their dermatosis, with a high frequency of ACD observed to textile dyes, isothiazolinones, and fragrances.
Major finding: Contact sensitization was significantly associated with facial involvement (P = .04) and a longer duration of AD (P = .005). The most frequent allergen was textile dye mix (24.70%) followed by nickel (20.21%), cobalt (12.70%), and methylchlorisothiazolinone+methylisothiazolinone (8.50%). The avoidance of relevant allergens led to a significant reduction in the Scoring of Atopic Dermatitis (SCORAD) scores at 6 months (P < .001).
Study details: This longitudinal prospective study included 93 patients with AD (age > 2 years) who were patch-tested with the 2019 European baseline series and the corticosteroid series, 60.2% of whom had positive patch test results.
Disclosures: This study did not disclose any funding source. The authors declared no conflicts of interest.
