[Translated article] Standard and Expanded Series Patch Testing Update by the Spanish Contact Dermatitis and Skin...

Area of Science:

• Dermatology
• Allergology
• Contact Dermatitis Research

Background:

• The Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) periodically reviews and updates standard patch test series.
• Previous standard series were established in 2016, necessitating updates based on evolving allergen prevalence and diagnostic needs.

Purpose of the Study:

• To detail the modifications made to the Spanish Standard Series patch testing.
• To inform dermatologists and allergists about the updated allergen composition for improved diagnosis of allergic contact dermatitis.

Main Methods:

• A meeting of the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) in October 2021 proposed changes.
• Specific allergens were added or excluded from the standard series based on expert consensus and epidemiological data.

Main Results:

• The 2022 Spanish Standard Series includes newly added allergens: hydroxyethyl methacrylate (2% pet.), textile dye mixture (6.6% pet.), linalool hydroperoxide (1% pet.), and limonene hydroperoxide (0.3% pet.).
• Ethyldiamine and phenoxyethanol have been excluded from the updated series.
• Additional allergens incorporated into the extended 2022 series include methyldibromoglutaronitrile, sesquiterpene lactone mixture, and hydroxyisohexyl 3-cyclohexene (Lyral).

Conclusions:

• The updated Spanish Standard Series patch testing aims to enhance the diagnostic capabilities for allergic contact dermatitis.
• These revisions reflect current trends in allergen exposure and sensitization, ensuring more relevant testing for patients.
