Background: The most reliable method to determine contact allergy (CA) is a standartised allergen patch test. Moreover, the anatomical site can help suspecting the cause of dermatitis.
Objectives: To evaluate the spectrum of the most and least common contact allergens and determine CA relation to body sites among patients with chronic dermatitis.
Methods: A retrospective study was performed in accordance with European Surveillance System on Contact Allergies (ESSCA) project and its standard protocol. Patch test results of European baseline series performed with 45 contact allergens in 2019-2020 were analysed at the Department of Skin and Venereal Diseases Kaunas Clinics.
Results: CA to nickel sulfate: among women – 21.9 % in 2019 and 20.0 % in 2020; among men – 2.7 % in 2019 and 2.1 % in 2020. CA to sodium metabisulphite among men: 8.1 % in 2019 and 8.3 % in 2020. No sensitization was observed to quaternium 15, hydroxyisohexyl 3-cyclohexene carboxaldehyde and parthenolide. Prevalence of hand CA in 2019 – 19.6 %, face and leg CA – 14.8 % and 4.23 %, and in 2020 – 19.1 %, 8.3 % and 10.12 %.
Conclusions: Nickel sulfate more often sensitizes women than men, while sodium metabisulfite – men than woman. In 2019 contact sensitization was observed in the hands and face more often than in the legs. Whereas in 2020, a significant relation between CA and its anatomic sites was not found. The most prevalent contact allergen in patients with hand and face dermatitis was nickel sulfate, while in patients with leg dermatitis – sodium metabisulfite.
