To characterize the plasma proteome profile in occupational dermatitis in workers from paint industry.
The study has a case-control design, comparing exposed workers with and without occupational contact dermatitis, matched for age, gender, occupational history and comorbidities. An immunological assay (Human XL Cytokine Array Kit – ARY022B, R&D Systems) was used to measure the plasma levels of 105 cytokines and chemokines in a pooled sample of the cases and a pooled sample of the controls.
A 1.5-fold increase was noticed for interleukin 3, interleukin 10 and leptin in cases, as compared to controls. Fibroblast growth factor-7 and growth/differentiation factor-15 showed a 1.4- fold increase, while interleukin 19, interleukin 31 and macrophage inflammatory protein 3 α had only a 1.3-fold increase. Leukemia inhibitory factor was the only plasma cytokine that showed a 1.3-fold decrease. All other cytokines had a variation of less than 1.2-fold between cases and controls.
The recognition of the molecular signatures is very important for an accurate and indisputable diagnosis of occupational contact dermatitis. In workers from paint industry, plasma levels of interleukins 3, 10, 13 and 19, fibroblast growth factor-7, and growth/differentiation factor-15 together with leukemia inducible factor may differentiate subjects with contact dermatitis from those without skin lesions.
