IGHE and asthma: According to these authors, remission in asthma can be defined in three ways: (1) clinical remission, defined as no significant symptoms or the use of corticosteroid medications for ≥ 1 2 months with improved lung function tests; (2) inflammatory remission, defined as very low or undetectable airway or serum biomarker levels (such as eosinophils, allergen-specific IgE, periostin, FeNO); or (3) complete remission, defined as the absence of asthma symptoms without the use of medication.
