At baseline, higher median concentrations of serum TARC (1936.5–4030.1 pg/mL) and total IgE (2396.0–4925.5 IU/mL) were observed in AD patients compared with asthma, CRSwNP and EoE patients (293.0–333.5 pg/mL [TARC]; 67.0–178.5 IU/mL [IgE]) (Table 1). Here, IGHE is linked to eosinophilic esophagitis.
