Total IgE level was significantly higher in patients with BE (160 vs 90 IU/mL; P = .006), but we observed no difference in allergic sensitization (62% vs 61%; P = .2) nor in the level of fractional exhaled nitric oxide (21 parts per billion vs 20 parts per billion; P = .8) in patients with and without bronchiectasis. Here, IGHE is linked to Barrett esophagus.
