OBJECTIVETo determine the distribution of allergens in patients with allergic rhinitis in Nanchang area and provide the clinical reference for management strategies with regional character.

METHODSPatients with symptoms of allergic rhinitis were given skin prick test (SPT) from March 2012 to May 2013. Among the patients, the distribution of all allergens was analyzed. The positive rate was compared with gender, age, occupation, season, course of disease and so on.SPSS 17.0 software was used to analyze the data.

RESULTSAmong 5 654 patients, the total positive rate of SPT was 56.07%, with dermatophagoides pteronyssinus (46.94%), dermatophagoides farina (35.99%), blomia tropicalis (31.34%) as the major allergens. With age increasing, the positive rate of allergen decreased. There was statistically significant difference (χ² = 261.372, P < 0.01) . There was significant difference of the positive rate in different occupations (χ² = 170.859, P < 0.01), the highest rate was found in student (66.12%) and the lowest was found in farmer (41.56%). There was significant difference of variation with months (χ² = 227.333, P < 0.01), the most in October, 68.88%. There was significant difference of the positive rate of dust mites in different seasons (χ² = 204.343, P < 0.01), the highest in autumn, the lowest in winter. There was no correlation between the positive rate and course of disease (P > 0.05).

CONCLUSIONSDust mites were identified as the most common allergens among patients with allergic rhinitis in Nanchang area.Occupation is one of the influencing factors for the positive rate.
