Eosinophilia was more prevalent in the EoE group than in the GERD individuals (10 (58.85%) vs. 10 (18.18%), p = 0.001), as well as an elevated total IgE (11 (64.70%) vs. 6 (10.9%), p = 0.001); no other biochemistry or hematological differences were detected (Table 2). Here, IGHE is linked to eosinophilic esophagitis.
