Introduction: Epoxy resins, widely used in several industrial sectors, are among the main causes of allergic contact dermatitis. The wind turbine production industry is one of the sectors that uses these products widely. This study aimed to assess the prevalence of contact allergy to epoxy resin and its components among wind turbine blades production workers with suspected contact dermatitis. Methods: We performed a retrospective analysis of the patch test results performed between 2012 and 2019 in wind turbine blades production workers with dermatitis and characterized their demographic and clinical data, patch test results and the occupational impact of allergic contact dermatitis on these workers. Results: Out of the 3049 patients patch tested in the period 2012-2019, we identified thirteen wind turbine blades production workers, predominantly male (69.2%). All of them handled glues, resins and/or paints in their daily work activities. Seven (53.8%) had a combination of hand dermatitis and airborne dermatitis, two (15.4%) had exclusively hand dermatitis and four (30.8%) had predominantly airborne dermatitis. All patients had positive patch test for epoxy resin and ten patients (76.9%) had also reaction for 1,6-hexanediol diglycidylether. Two patients (15.4%) also had a reaction to the already hardened resin powder. Four (30.8%) patients had to quit their jobs due to allergic contact dermatitis and three (23.1%) were transferred to another workstation without exposure to epoxy resin. Avoidance of exposure resulted in a significant improvement. Conclusion: With this study, we confirmed that epoxy resin and its components are the main cause of dermatitis among wind turbine blades production workers, that eczema occurs by direct contact and by airborne exposure.

The Impact

Introduction. Occupational Allergic Contact Dermatitis is a very common occupational disease and epoxy resins are among its main causes. The aim of this study was to characterize patients with positive patch test reactions to epoxy resin detected in the Coimbra Hospital and University Center between 2012 and 2018 and compare with the results of patients patch tested between 1999 and 2008 at the same Institution. Method and Materials.  Within aretrospective analysis of the files of patients with positive patch test reactions (1+ or more intense) to epoxy resin of bisfenol A tested at 1% pet. within the Baseline Series between 2012 and 2018, we characterized demographic and clinical data of reactive patients, evaluated the relevance of the reaction, sources of exposure to epoxy resin with particular attention to occupational exposures, other positive reactions and the impact of the results of the tests in the work conditions of these patients. Lastly, we compared these results with a previous study performed in the same Hospital between 1999 and 2008. Results. Among 2363 patch tested patients during the study period we found 23 patients (0.97%), 17 males and 6 females, who developed contact allergy to epoxy resins. In 22 cases we identified a relevant occupational exposure: 9 from construction industry; 9 workers from wind-mill turbines factory for Eolic energy; 2 from fiberglass factories; 1 from a chemical factory and 1 from a Wastewater Treatment Plant. In 1 patient (a teacher) no relevance was found. Of these 22 workers, 9 (39.1%) had both hand and airborne lesions, while 8 (34.8%) had lesions exclusively on the hands and 5 (21.7%) had predominately airborne dermatitis. Four of the 23 (17.4%) reacted exclusively to the epoxy resin, and 11 of 18 (61.1%) also reacted to 0.25% hexanediol diglycidyl ether. Avoidance resulted in a significant improvement of symptoms. Compared to the previous period (1999-2008), there are no significative changes apart from a slight increase in the frequency of the allergic reactions to epoxy resins and its main source of exposure. Conclusions. The prevalence of allergic contact dermatitis to epoxy resin has slightly increased in this Portuguese Center mostly due to workers from wind-mill turbines factory for Eolic energy, a recent industry implanted in this region. This allergen still causes almost exclusively occupational dermatitis, either hand, airborne, or both.

Occupational Contact

Occupational population-based epidemiological data relating to occupational contact allergies in the Chinese clothing industry are limited. To investigate the prevalence of occupational allergic contact dermatitis (OACD) and to identify the causative allergens among clothing employees in China, a cross-sectional study was conducted in 529 clothing employees at 12 clothing factories in Beijing. All employees were subjected to an interview using self-administered questionnaire and skin examination, and those who were diagnosed with occupational contact dermatitis (OCD) were patch tested. In the present survey, we found that the overall 1-year prevalence of OACD among the clothing employees was 8.5%. The 1-year prevalence of OACD among workers (10.8%) was significantly higher than that among managers (3.2%). The lesions were primarily on the hands and wrists in workers, but the face and neck in managers. The major allergens were nickel sulfate and cobalt dichloride in workers and colophony andp-tert-butylphenol formaldehyde resin in managers. In conclusion, workers are at a higher risk of OACD compared with managers in the Chinese clothing industry. In addition to hand dermatitis in workers, airborne contact dermatitis on the face and neck should be also addressed in managers.
