To investigate the inhaled allergens spectrum of 890 allergic rhinitis patients in Shanghai, and to provide basic epidemiologic information for the prevention and treatment of allergic rhinitis.
Thirteen allergens skin prick test results of 890 allergic rhinitis patients recruited were retrospectively analyzed.
The main common inhaled allergens in allergic rhinitis patients in Shanghai were house dust mite (91.24%), dermatophagoides farinae (86.58%), tropical mite (51.98%), dog hair (15.96%). Moreover, the positive frequency was decreased with age increasing, and gender group had no obvious difference.
House dust mite and dermatophagoides farinae were the main allergens of allergic rhinitis patients in Shanghai. Skin prick test is helpful for the discovery of the allergens so as to provide important basis of immunotherapy.
[Show abstract][Hide abstract] ABSTRACT: Allergic rhinitis (AR) is a serious systemic allergic disease, which together with comorbid asthma causes major illness and disability worldwide. Recent epidemiological studies have revealed wide variations in the increasing prevalence of AR and allergies globally, including in China. Despite a markedly higher population than western countries, and a landmass close to Europe in area, little epidemiological data is available on AR in China. Thus, the present study reviewed the prevalence, comorbid allergic diseases, trends and pattern of sensitizing allergens in adults and children suffering from AR in China. Available data indicated that despite variations in the prevalence of AR in different regions of the country, the prevalence of AR has increased in both adults and children over the last 2 decades. Similarly, there has been an increase in a "western"-type lifestyle, industrialization and air pollution over this period, which may have contributed to the increased prevalence of AR observed in China.
[Show abstract][Hide abstract] ABSTRACT: Artemisia is the most important outdoor allergen throughout China. It can cause allergic rhinitis, asthma, or both of them. Since it was verified as an allergenic pollen in 1960, it was identified two times in the Chinese National Pollen Survey (1984, 2009). The first oral immunotherapy double-blinded trial for Artemisia pollen asthma research was conducted in China in 1989 and published in 1990. 40 years since that study, there have been many published research reports on Chinese Artemisia allergy. This review summarizes the information regarding the discovery of Artemisia as an allergenic pollen, pollen account, epidemiology, allergen components, immunological changes in hay fever patients, natural course from rhinitis to asthma, diagnosis, and immunotherapies in China.
