Nasal eosinophilia in allergic and nonallergic rhinitis: usefulness of the nasal smear in the diagnosis of allergic rhinitis.

摘要: Diagnostic nasal cytology has been advocated for use in distinguishing allergic from nonallergic rhinitis. We sought to determine prospectively the frequency of eosinophilia (NE) 100 patients whom having rhinitis (AR), rhinitis, and other atopic conditions not involving respiratory tract have diagnosed. A smear was obtained consenting adults using Rhino-Probe curette. Patients taking local or systemic corticosteroids, those with chronic associated aspirin sensitivity, sinusitis were excluded. All cytograms coded read by a single "blinded" investigator. NE considered significant if greater than 20% sampled cells eosinophils. Twenty-six 61 (43%) AR had NE. No detected control population skin test negative group One 16 disease exhibited NE; this patient dermatitis peripheral eosinophilia. cases eosinophilic detected. There no correlation symptoms number positive tests These data suggest that eosinophils is an insensitive but specific diagnosis when polyposis sensitivity and/or are
