title: Allergic and nonallergic rhinitis. Diagnosis and management.
abstract: The causes of rhinitis are many. Allergic rhinitis is mediated by IgE, and immunotherapy in selected patients is very effective. Immunoglobulins do not seem to play a role in nonallergic rhinitis, and immunotherapy is ineffective. Correct diagnosis spares the patient needless expense, inconvenience, and eventual disappointment.
