A similar 3‐month intervention which combined all three components of the EED, TED, and ED was studied by Kalach et al 201363 in a retrospective cohort study of patients with EoE (n = 49), which found remission (defined as <5 eosinophils/hpf with no symptoms) in 53% of cases, as well as significant decreases in blood eosinophils (P < .0001), IgG (P = .003), and IgM (P < .05) levels. This evidence concerns the gene CD40LG and eosinophilic esophagitis.
