[Analysis of inhaled and food allergen spectrum of patient with allergic rhinitis in north of Zhejiang].

OBJECTIVE

To explore the inhaled and food allergen distribution of patient with allergic rhinitis in north of Zhejiang and to analyze the difference of allergen distribution among different age groups.

METHOD

One thousand and forty eight patients in north of Zhejiang diagnosed with allergic rhinitis in our outpatient department were tested with skin prick test (SPT). The positive rate of inhaled and food allergens were calculated. To analysis the difference of positive rate between children and adult.

RESULT

Nine hundred and eighty-eight cases (94.3%) had the positive reaction. Dermato phagoides farinae and Dermatophagodies pteronyssinus had the highest positive ratio (72.1%, 71.8%) in inhalation group, followed cockroach (14.1%). In food group, Shrimp and peanuts had the highest positive ratio (18.3%,14.2%). Between children group and adults group, positive rate of food allergen was significantly different (P < 0.05), but of inhaled allergen was not significantly different.
