[The analysis of AllergyScreen results among allergic patients of different age groups].

OBJECTIVE

To investigate the positive rates of some allergens in different age groups of allergic rhinitis patients, and to analyze the relationship between serum specific immunoglobulin E(sIgE) and total immunoglobulin E(IgE).

METHOD

Six hundred and fifty-three patients with allergic rhinitis, tested by AllergyScreen system, were enrolled in our research.

RESULT

The positive rate of sIgE in all patients was 85.5%. The positive rate of dust mite was the highest with the result of 76.3%, and the positive rate of feline or dogs hair was the lowest of 20.3%. The statistical significance of different positive rate of some allergens were found in the different age groups. All the patients were divided into two groups, one was younger than 18 years old group, which including 18 years old and another was older than 18 years old group. Except Mx, the positive rate of other allergens existed statistical difference. The level of serum total IgE could not reflect the positive rate of sIgE completely.

CONCLUSION

It is an effective and reliable method of the diagnosis of allergic rhinitis to combine the analysis of total serum IgE and sIgE levels with patients clinical manifestations. Different strategies should be employed for the prevention and treatment of allergic rhinitis according to their ages.
