Diagnostic Criteria and Treatment Guidelines for Allergic Rhinitis

Clinical Diagnosis

The American Academy of Otolaryngology-Head and Neck Surgery recommends that allergic rhinitis be diagnosed clinically when patients present with one or more symptoms, such as nasal congestion, runny nose, itchy nose, or sneezing, combined with a history of symptoms after allergen exposure, and confirmed by positive specific IgE testing when the diagnosis is uncertain or empiric treatment fails 1
The diagnosis relies on three key components: symptom presentation, history of allergen exposure, and physical examination findings, as suggested by the Journal of Allergy and Clinical Immunology 2, 3
Symptoms must correlate temporally with exposure to suspected allergens, according to the Journal of Allergy and Clinical Immunology 2, 3

The American Academy of Otolaryngology-Head and Neck Surgery suggests that specific IgE testing, preferably skin testing, should be performed when patients fail empiric treatment, when diagnosis is uncertain, or when knowledge of specific allergens is needed to guide avoidance or immunotherapy 1
Skin prick/puncture tests are the preferred diagnostic method due to simplicity, rapid results, low cost, and high sensitivity, as stated by the Journal of Allergy and Clinical Immunology 2, 8

The American Academy of Otolaryngology-Head and Neck Surgery recommends that intranasal corticosteroids be used as the most effective first-line treatment for persistent moderate-to-severe allergic rhinitis, alone or combined with intranasal antihistamines 1
Second-generation antihistamines are strongly preferred over first-generation agents due to reduced sedation, performance impairment, and anticholinergic effects, according to the Journal of Allergy and Clinical Immunology 7, 3
Leukotriene receptor antagonists should not be offered as primary monotherapy for allergic rhinitis, as suggested by the American Academy of Otolaryngology-Head and Neck Surgery 1
Allergen immunotherapy should be offered to patients with inadequate response to pharmacotherapy with or without environmental controls, according to the American Academy of Otolaryngology-Head and Neck Surgery 1
Inferior turbinate reduction may be offered to patients with nasal airway obstruction and enlarged inferior turbinates who have failed medical management, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 1
