Total IgE antibodies and allergen-specific IgE antibodies in each sample of nasal mucosal tissue from 11 allergic rhinitis patients were measured with the AlaSTAT 3gAllergy assay. We compared the levels of total IgE and IgEs specific for house dust (HD), mites, and cedar pollen in the serum and the inferior turbinate.
The total IgE levels and the cedar pollen-specific IgE levels in the inferior turbinate mucosal tissue correlated significantly with their respective levels in serum. The HD- and mite-specific IgE levels in the inferior turbinate mucosal tissue did not correlate significantly with their respective levels in the serum.
Our results evaluating the correlations between nasal mucosal and serum levels of antigen-specific IgE indicate that IgE produced in the nasal mucosa affects the IgE levels in the serum, especially the cedar pollen-specific IgE.
