Contact sensitivity to 2‐hydroxyethyl methacrylate in consecutive patients: A 1‐year multicentre SIDAPA study

Acrylates and methacrylates, here referred to as (meth)acrylates, arereactive monomers that polymerize into polymer plastics.1They arewell-known sensitizers in occupational (eg, dental materials)2and non-occupational (eg, dressings and wound care products) settings.3Anincreasing source of contact sensitivity comprises (meth)acrylate-containing nail products4; emerging sources of (meth)acrylate allergyare medical devices.52-Hydroxyethyl methacrylate (2-HEMA) haspreviously been suggested as a marker of contact allergy to (meth)acrylates.6The addition of 2-HEMA 2% pet. to baseline patch testseries was recommended by the British Society for Cutaneous Allergyin July 20187and by the ESCD in January 2019.1In this study, theprevalence of 2-HEMA contact allergy as a marker of (meth)acrylate allergy in an Italian patient sample was analysed
