IGHE and Eczematoid dermatitis: This study examined the association of phthalate metabolites with allergic symptoms (wheeze, allergic rhinoconjunctivitis, and eczema), T2 biomarker (fraction of exhaled nitric oxide (FeNO), blood eosinophil count, and total immunoglobulin E (IgE)), and non-T2 biomarker (absolute neutrophil count (ANC)) and also their association with oxidative stress biomarkers, such as 4-hydroxynonenal, hexanoyl-lysine, and 8-hydroxy-2-deoxyguanosine.
