| Abstract (English): |
Objectives: To evaluate the prevalence of methylisothiazolinone (MI) sensitivity and associated factors in individuals with suspected allergic contact dermatitis. Methods: Cross-sectional study based on patch tests, including methylisothiazolinone 0.2%, in 286 participants with suspected allergic contact dermatitis, in Brasília/DF, Brazil, between March/2020 and March/2022. Results: 13.6% of participants were diagnosed with allergic contact dermatitis and sensitive to MI. The mean age was 43.7 years, and the majority were women (71,8%). The average duration of the disease was 60 months. The most common location was hands (76.9%) and upper limbs (33.3%). In 97.4%, allergy to methylisothiazolinone was considered of current relevance. In the multivariate model, being domestic/household increased the chance of presenting sensitivity to MI by 4.2 (95% CI= 1.36 - 13.5). Presenting lesions in several places of the body was also significantly associated (OR=2.84; CI 95%=1.17 - 6.86) to be sensitive to the test substance. Conclusion: The findings confirm the epidemic of allergy to methylisothiazolinone. They reinforce the need for the inclusion of this isolated substance in the Brazilian baseline series. We emphasize the need for regulations on the use of methylisothiazolinone in industrial products and household detergents, as is done for cosmetics. Studies in other centers are needed to confirm these results. [ABSTRACT FROM AUTHOR] |

Objetivo: Evaluar la prevalencia de sensibilidad a la metilisotiazolinona y los factores asociados en individuos con sospecha de dermatitis alérgica por contacto. Métodos: Estudio transversal, llevado a cabo en pacientes con sospecha de dermatitis alérgica por contacto, a quienes se aplicaron pruebas de parche, incluida la metilisotiazolinona al 0.2%, atendidos en Brasilia/DF, Brasil, entre marzo de 2020 y marzo de 2022. Resultados: Se registraron 286 pacientes con dermatitis alérgica por contacto. El 13.6% de los participantes fueron diagnosticados con dermatitis alérgica de contacto y sensibles a metilisotiazolinona. La edad media fue de 43.7 años y la mayoría fueron mujeres (71.8%). La duración media de la enfermedad fue de 60 meses. La localización más frecuente fueron las manos (76.9%) y los miembros superiores (33.3%). En el 97.4% la alergia a la metilisotiazolinona se consideró de relevancia actual. En el modelo multivariante, ser ama de casa incrementó la probabilidad de padecer sensibilidad a la metilisotiazolinona en 4.2% de los casos (IC95%: 1.36 - 13.5). Manifestar lesiones en diferentes sitios anatómicos también tuvo asociación significativa (OR: 2.84; IC95%: 1.17 - 6.86) de tener sensibilidad a la sustancia de ensayo. Conclusión: Los hallazgos confirman la epidemia de alergia a la metilisotiazolinona. Refuerzan la necesidad de inclusión de esta sustancia aislada en las series de referencia brasileñas. Es importante reglamentar el uso de metilisotiazolinona en productos industriales y detergentes domésticos, como se hace con los cosméticos; por tanto, se requieren estudios adicionales, en otros centros, para confirmar estos resultados.
