Background |
Allergic contact dermatitis is an increasingly recognized clinical problem in children.
Objective |
The aim of our study was to evaluate contact sensitization in patients younger than 3 years of age with suspected contact dermatitis.
Methods |
During a 6-year period (2002-2008), 321 children underwent routine patch testing with a screening pediatric standard series of 30 allergens.
Results |
Two hundred children (62.3%; 102 girls and 98 boys aged 3-36 months [mean age 27 + 5.6 months]) developed at least one positive reaction. The most frequent reactions were to nickel sulfate (26.8%), followed by potassium dichromate (9%), cocamidopropylbetaine (7.2%), cobalt chloride (6.2%), neomycin sulfate (5%), and methylchloroisothiazolinone/methylisothiazolinone (4.4%). The prevalence of contact sensitization was similar in children with (61.3%) and without (63%) atopic dermatitis.
Limitations |
The prevalence of contact sensitization in children younger than 3 years of age was not compared with the prevalence in older children.
Conclusion |
A high prevalence of contact sensitization was found in preschool children, even younger than 3 years of age. Patch testing should be considered in this age group when persistent dermatitis does not respond to conventional treatment.
