The symptoms, duration, severity, and comorbidities of LAR are similar to those of allergicrhinitis. Although pathophysiology of LAR is not fully understood, in some patientsspecific IgE can be demonstrated in the nasal secretions. The diagnosis currently relies on thepositive results of nasal provocation test. Nasal provocation test has shown high sensitivityand specificity with safety, and is considered as the gold standard. LAR patients benefit fromthe same therapeutic strategies as allergic rhinitis patients, including the avoidance of allergenexposure and the pharmacotherapy. Effectiveness and safety of allergen immunotherapy opena window of treatment opportunity in LAR. This review provides a current update on LAR.
