Abstract:Objective To study the allergen spectrum of child patients with allergic rhinitis (AR) in Shenzhen Bao’an area. Methods 650 pediatric patients with suspected AR were given skin prick test (SPT) of 13 items and SIgE detection to determine the allergens. Results 451 patients (69. 38%) showed positive SPT results. Of them, 37 were caused by single allergen, 414 by two or more allergens, and inhaled allergens were the major ones. 43 had history of asthma. As for the causative allergens, 390 (86.5% ) were house dustmites, and 346 (76.7%) were dust mites. The total positive rate of serum SIgE detection was 83.3%. In the age group of 4~7 years, positive rates of SPT and SIgE were 90.8% and 87.3% respectively, while dust mites and house dust mites were the major allergens. The rates of children sensitized to wholeeggs and milk in the group of 4~7 years were significant higher than those of group 8~14 years (69.6% ∶78.1%). Conclusion Allergic rhinitis is one of the risk factors for asthma. As the most common allergens causing pediatric AR in Shenzhen Bao’an area, Dermatophagoides pteronyssinus and dermatophagoides culinae should be regarded as the focal points for prevention.
