Abstract:
Local allergic rhinitis (LAR) is a localized nasal allergic response in the absence of systemic atopy. The symptoms, duration, severity, and comorbidities of LAR are similar to those of allergic rhinitis. Although pathophysiology of LAR is not fully understood, in some patients specific IgE can be demonstrated in the nasal secretions. The diagnosis currently relies on the positive results of nasal provocation test. Nasal provocation test has shown high sensitivity and specificity with safety, and is considered as the gold standard. LAR patients benefit from the same therapeutic strategies as allergic rhinitis patients, including the avoidance of allergen exposure and the pharmacotherapy. Effectiveness and safety of allergen immunotherapy open a window of treatment opportunity in LAR. This review provides a current update on LAR.
