Conversely, we did not observe increased concentrations of the IL-20 subfamily cytokines in plasma from our EoE children, on the opposite to recent observations in adults (37), nor increased concentrations of IL-4, IL-5, IL-13, IL-6, IL-8 or IL-1α as observed but not reproduced in (32). This evidence concerns the gene IL4 and eosinophilic esophagitis.
