The serum levels of IgE, IgA, IgG, IgG4, IL-6, IL-4, IL-15 and IL-8. A–D The serum levels of IgE and IgG4 were measured by ELISA, and IgA and IgG measured by immunoturbidimetry. E–H The concentrations of IL-6, IL-4, IL-15 and IL-8 were determined by the Luminex200 platform. HC, healthy controls, n = 28; AR, allergic rhinitis, n = 30; ACD, allergic contact dermatitis, n = 12; AR + ACD, allergic rhinitis combined with allergic contact dermatitis, n = 15.*p < 0.05, **p < 0.01, and ***p < 0.001 (one-way ANOVA and Tukey's multiple comparisons test)
