[Prevalence of sensitization to aeroallergens in Beijing patients with allergic rhinitis].
OBJECTIVE
The purpose of this study was to determine which aeroallergens were prevalent in patients with allergic rhinitis in Beijing.


METHODS
A total of 554 cases (female: 212, male: 342, aged between 4-69 years) who were diagnosed with allergic rhinitis by history and clinical presentation, underwent a skin prick test with 20 standardized aeroallergens, and the important sensitizing allergens were assessed. The samples were stratified on two age groups: 4-18-year-olds (children group, n = 81) and 19-60-year-olds (adults group, n = 401). Difference of SPT responses of the two groups was investigated.


RESULTS
The percent of patients with positive skin tests were follow:D. farinae (64.6%), D. pteronyssinus (64.3%), Flowers pollen (28.7%), Herbs (26.5%), Lamb's Quarters (13.7%) ,Tree II (13.5%), Giant Ragweed (12.5%). Tree I (12.5%) There were significantly higher sensitivity to dust mite among children group compared to adults group (P < 0.01).


CONCLUSIONS
The study shows that the dust mite, Flowers pollen and Herbs are the most important three aeroallergens in Beijing region.
