Local Allergic Rhinitis
Local allergic rhinitis is an allergic reaction in the nose to an allergen, without systemic allergies. So skin-prick and blood tests for allergy are negative, but there are IgE antibodies produced in the nose that react to a specific allergen. Intradermal skin testing may also be negative.
The symptoms of local allergic rhinitis are the same as the symptoms of allergic rhinitis, including symptoms in the eyes. Just as with allergic rhinitis, people can have either seasonal or perennial local allergic rhinitis. The symptoms of local allergic rhinitis can be mild, moderate or severe. Local allergic rhinitis is associated with conjunctivitis and asthma.
In several studies, over 40% of people who had been diagnosed with nonallergic rhinitis were found to actually have local allergic rhinitis.
Steroid nasal sprays and oral antihistamines have been found to be effective for local allergic rhinitis. A preliminary study found that allergy shots were also effective.

Famous quotes containing the word local:
“America is the world’s living myth. There’s no sense of wrong when you kill an American or blame America for some local disaster. This is our function, to be character types, to embody recurring themes that people can use to comfort themselves, justify themselves and so on. We’re here to accommodate. Whatever people need, we provide. A myth is a useful thing.”
—Don Delillo (b. 1926)
