Allergists have unique training and experience in diagnosis and management of concurrent allergic conditions, including atopic dermatitis, anaphylactic IgE-mediated food allergy, asthma, and allergic rhinitis, with most allergists routinely prescribing medications such as antihistamines, topical/inhaled/intranasal corticosteroids, and biologics [1, 133]. Here, IGHE is linked to atopic eczema.
