[Analysis of total and specific IgE in serum of carvota mitis pollen-induced allergic rhinitis patients].

OBJECTIVE

Exploring the relationship between total and specific IgE in serum and allergen skin test of carvota mitis pollen-induced allergic rhinitis patients.

METHOD

Four hundred and-twenty-nine carvota mitis pollen-induced allergic rhinitis patients and 243 healthy control subjects were recruited. The experimental group carried out skin tests. and pollen-specific IgE were also examined by BSA-ELISA method. Total IgE in serum of all of the subjects were determined by ELISA.

RESULT

The positive rate of the total IgE level of the patients were much higher than those of the controls (66.2% vs. 15.6%, P < 0.01). No statistically significance was found between the positivity of skin test and serum specific IgE of the experimental group (chi2 = 0.758 8, P > 0.05). The difference between serum-specific IgE and total IgE was statistically significant (chi2 = 50.639, P<0.01). There was no statistical significance of specific IgE and the total IgE in serum between long term residents in Haikou and Hainan Tourisms (P > 0.05).

CONCLUSION

Allergen skin test and carvota mitis pollen-specific IgE are two effective methods for the diagnosis of carvota mitis pollen-induced allergic rhinitis. The detection of total IgE in serum of carvota mitis pollen-induced allergic rhinitis provides a reference value for diagnosis. The relationship between concentration of IgE in serum of the carvota mitis pollen-induced allergic rhinitis and allergen contact duration is waiting for further study.
