AbstractThe proportion of allergic diseases attributable to atopy remains a subject of controversy. This study aimed to estimate the population risk of physician-diagnosed asthma, rhinitis and eczema attributed to atopy among a population sample of Asian school-age children. Asian children aged 5–18 years (n = 1321) in the Prediction of Allergies in Taiwanese CHildren (PATCH) study were tested for serum allergen-specific immunoglobulin E. Physician-diagnosed asthma, rhinitis and eczema were assessed by a modified International Study of Asthma and Allergies in Childhood questionnaire. Atopy was defined as the presence of serum allergen-specific immunoglobulin E. In this population-based study, 50.4% of the subjects with asthma, 46.3% with rhinitis, and 46.7% with eczema were attributable to atopy. The population attributable risk (PAR) of atopy for three allergic diseases was higher in adolescents (asthma, 54.4%; rhinitis, 59.6%; eczema, 49.5%) than younger children aged less than 10 years (asthma, 46.9%; rhinitis, 39.5%; eczema, 41.9%). Among the seven allergen categories, sensitization to mites had the highest PARs for all three allergic diseases (51.3 to 64.1%), followed by sensitization to foods (asthma, 7.1%; rhinitis, 10.4%; eczema 27.7%). In conclusion, approximately half (46.3 to 50.4%) of Asian children in Taiwan with allergic diseases are attributable to atopy.

BACKGROUND: Respiratory disease is a major cause of morbidity in young people. It is now recognized that atopy plays an important role in the development of chronic respiratory symptoms in children.OBJECTIVE: To examine the determinants and consequences of serum total and specific immunoglobulin E (IgE) in a general population sample of Québec children and adolescents.METHODS: In 1999, 2349 children and adolescents (nine, 13 or 16 years of age) who had participated in a respiratory symptom and disease questionnaire had their total IgE measured. Of these participants, a subsample of 451 children and adolescents was analyzed to detect antibodies to eight specific allergens (ie, allergens of dust mites [Dermatophagoides farinae and Dermatophagoides pteronyssinus], cat, dog, ragweed, Timothy grass, mould [alternaria] and cockroach).RESULTS: The geometric mean of the total IgE was 44.4 U/mL among all participants. Concentrations were higher in boys and increased with age. More than 41% of the participants were sensitized to at least one specific allergen. Such sensitization was strongly associated with the occurrence of respiratory conditions and symptoms, namely asthma, wheezing and rhinitis. Family history, school location and ethnic origin had an impact on the prevalence of atopy and total IgE levels.CONCLUSIONS: Allergic sensitization is a major determinant in the development of asthma, wheezing and rhinitis in children and adolescents in the province of Québec.

<b><i>Background:</i></b> Light-initiated chemiluminescence assay (LICA) is a homogeneous assay that has been successfully used for the quantitation of food allergen-specific immunoglobulin E (sIgE), but not inhaled allergen-sIgE. Simultaneously, current assays used to detect allergen-sIgE are serum consuming and/or time consuming. Hence, we established a method for the quantitation of <i>Artemisia</i>-sIgE based on LICA and verified its performance according to the clinical guideline documents, laying a foundation for the quantitation of inhaled and food allergen-sIgE in parallel on LICA. <b><i>Methods:</i></b> The assay was established after optimizing the first incubation time and the dilutions of <i>Artemisia</i>-coated chemibeads, biotinylated goat anti-human IgE, and serum. In order to quantitate <i>Artemisia</i>-sIgE, the calibration curve was established with a high positive serum of known concentration. The assay performance was confirmed per the clinical guideline documents. In addition, the correlation between the results of LICA and capture enzyme-linked immunosorbent assay was evaluated. <b><i>Results:</i></b> The developed LICA’s coefficients of variation of repeatability and intermediate precision were 3.20%, 2.14%, and 3.85% and 4.30%, 4.00%, and 4.40%, respectively. The limit of detection was 0.10 kU<sub>A</sub>/L, and the limit of quantitation was 0.11 kU<sub>A</sub>/L. The range of linearity was from 0.27 kU<sub>A</sub>/L to 97.53 kU<sub>A</sub>/L (<i>r</i> = 0.9968). The correlation coefficient (<i>r</i>) for the correlation analysis between results of LICA and capture ELISA was 0.9087. This assay was successfully applied in 64 human serum samples, showing good sensitivity (82.20%) and specificity (100%). <b><i>Conclusion:</i></b> An <i>Artemisia</i>-sIgE quantitation assay based on LICA was successfully established. Its performance satisfied the clinical requirements and could be widely used in clinical laboratories.

Aim. To assess the rate of sensitization to the grades of apples of various colours and analyze the association of the obtained indices and total sIgE levels of these grades with the severity of atopic dermatitis. Materials and methods. The blood sera of 215 patients, suffering from alimentary allergy, were studied. The detection rate of sensitization and that of specific immunoglobulin E (sIgE) concentration sum to allergens of apple grades with various coating colours as well as the association of these indices with the degree of severity of atopic dermatitis (AD) was analyzed. Test-systems were used for immune-enzyme analysis of production. Statistical analysis of the obtained results was performed using the program “MedStat” (Donetsk). Results. It was shown that the detection rate of sensitization to the grades with mixed red colour is reliably higher (p < 0.001) compared to the grades without coating colour. The degree of AD severity correlates with the total quantity of apple grades, to which sensitization has been revealed (p < 0.01), with the quantity of grades with mixed red colour, to which sensitization has been found (p < 0.01) and with sIgE sum to the grades with mixed red colour (p < 0.01). Reliable differences (p = 0.006) in the degree of severity of atopic dermatitis among persons, sensitized to apple grades and with no sensitization to this fruit were established. Conclusions.The obtained data are to be used when choosing a diet and correcting it for persons with alimentary allergy and atopic dermatitis.
