A distinguishing feature of NARES is the presence of eosinophils, usually 10-20% on
nasal smears. In general, patients with NARES present with
nasal congestion, sneezing, rhinorrhea,
nasal pruritus, and hyposmia. NARES is more frequent in females at mean age. Family history is positive in part of cases. The clinical symptoms are sneezing, watery rhinorrhea, nasal obturation and nasal itching. The precipitating factors are often nonspecific irritants, weather changes or strong odors.
