The Rising Incidence of Allergic Contact Dermatitis to Acrylates

Background Allergic contact dermatitis (ACD) caused by (meth)acrylates used in nail products is being increasingly reported in nail technicians and consumers. Objectives The aim of the study was to assess the incidence of sensitization to (meth)acrylates in technicians and users of nail products with ACD, referred for patch testing in a tertiary center, during the last 10 years. Methods All patients with ACD, who reported a profession associated with cosmetic nail procedures or use of such services and were referred for patch tests in our department between January 2009 and December 2018, were identified. The incidence of positive sensitization to (meth)acrylates was assessed. Results Contact allergy to 1 or more (meth)acrylates was found in 116 (74.4%) of 156 nail technicians or nail product users, all women. One hundred thirty-eight (88.5%) were occupationally exposed, and 18 (11.5%) were consumers. In addition, there was a statistically significant increase in (meth)acrylate ACD during 2014-2018 (100/127 cases [79%]) when compared with 2009-2013 (16/29 cases [55%]). The most common sensitizer among the 156 allergic individuals was ethylene glycol dimethacrylate, which was positive in 113 cases (72.4%), and among patients with acrylate-positive patch test, the rate was 97.4%. Conclusions Our experience confirms the worldwide changing landscape of rising (meth)acrylate sensitization in nail technicians and nail products users with ACD. Efforts to improve prevention are needed, and clinicians should have a high index for suspicion in this occupational group. © Lippincott Williams & Wilkins.
