Background Allergen micro-arrays are powerful tools for screening of serum IgE-reactivity. In this study allergen micro-arrays were used to identify dominating IgE-binding allergens and cross-reactivity patterns among selected Chinese allergy patients. Methods The study was conducted using patient sera from the cities of Guangzhou, Nanjing, Chengdu and Shenyang. In total 100 sera with Dermatophagoides pteronyssinus (Der p) specific IgE-levels higher than 50 kU/L were selected for testing against 103 individual allergens. Results Among 100 selected patients, 95% showed IgE-reactivity towards house-dust mite allergens Dermatophagoides farinae (Der f) 1, Der f 2 and Der p 2 and 94% were IgE positive against Der p 1, and 60% of sera contained IgE reacting against allergen Euroglyphus maynei (Eur m) 2. IgE against cat allergen, Felisdomesticus (Fel d) 1, was seen in 20%. Only 2% showed specific IgE-reactivity to Der p 10, a panallergen belonging to the tropomyosin family. Serum IgE-reactivity towards other allergens was in general low. IgE-reactivity against pollen allergens showed geographic differences. Conclusions This study clearly confirms that group 1 and group 2 are major allergens of house dust mites. These selected house-dust mite allergy patients are close to being mono-sensitized. Der p 10 is not an important allergen for cross-reactivity. Specific IgE-sensitization towards pollen allergens is low in southern China compared to other regions. The prevalence of food and stinging insect allergens known to give rise to IgE-mediated cross-reactivity is 2% or less. 展开更多

Background: Birch pollen sensitization and associated pollen-food syndrome among Chinese allergic patients have not been investigated. Methods: Sera from 203 allergic patients from the northern part of China and collected during February to July 2014 were investigated. Specific immunoglobulin E (IgE) against birch pollen extract Bet v and major birch pollen allergen Bet v 1 were measured using the ADVIA Centaur. The presence of major apple allergen Mal d 1 and soy bean allergen Gly m 4 specific IgE was measured by ImmunoCAP 100. Results: Among the 203 sere, 34 sera (16.7%) had specific IgE to Bet v and of these, 28 sere (82.4%) contained Bet v 1-specific IgE. Among the 28 sera with Bet v 1-specific IgE, 27 sera (96.4%) contained Mal d 1-specific IgE and 22 sera (78.6%) contained Gly m 4-specific igE. Of the 34 Bet v-positive sera, 6 sera (17.6%) contained no specific IgE for Bet v 1, Mal d 1, or Gly m 4. Almost all Bet v-positive sera were donated during the birch pollen season. Conclusions: The prevalence of birch allergy among patients visiting health care during pollen season can be as high as 16.7% in Tangshan City. The majority of Chinese birch allergic patients are IgE-sensitized to the major birch pollen allergen Bet v 1 as well as to the major apple allergen Mal d 1 and soy bean allergen Gly m 4. A relatively high number of patients (17.6%) are IgE-sensitized to birch pollen allergen(s) other than Bet v 1. The high prevalence of specific IgE to Mal d 1 and Gly m 4 among Bet v 1-sensitized patients indicates that pollen-food allergy syndrome could be of clinical relevance in China. 展开更多

Background Objective evaluation of allergic rhinitis (AR) requires in vivo and in vitro tests. In vitro tests are important to assist or ensure the main allergens in multi-allergen-sensitive patients. The aim of this study was to evaluate the utility of serum specific IgE (slgE) in the diagnosis of AR patients with multi-allergens in the Chinese population.Methods Combining a positive skin prick test (SPT) and clinical history as the diagnostic reference criteria of AR, we estimated concentrations of slgE produced in response to the 7 most frequent allergens among 85 AR patients, using the UniCAP assay system.Results Among 85 individuals with positive SPT results and allergen-specific nasal symptoms, slgE concentration correlated well with SPT classes among all the tested allergens. Based on a clinical diagnosis and SPT results using a positive cut-off value of a class 1 score, the CAP test performed well and the sensitivity for different allergens ranged from 0.5 (giant ragweed) to 0.91 (Dermatophagoides pteronyssinus (Der p) and Dermatophagoides farinae (Der f), while specificity ranged from 0.93 (Der f) to 1.0 (animal hair, Derp and mugwort). When the cut-off score was adjusted to class 2, the sensitivity showed an increase overall while the remaining assessed items, including specificity, positive predictive value, negative predictive value and efficiency, showed an unacceptable decline.Conclusions Well-established serum slgE tests correlated well with SPTs. Setting a class 1 cut-off for positivity of SPT results was better than a class 2 setting for assessing the AR diagnostic value. 展开更多
