Direct intranasal application of the solid phase of ImmunoCAP® increases nasal specific immunoglobulin E detection in local allergic rhinitis patients

Background

The measurement of nasal specific IgE (NsIgE) in local allergic rhinitis (LAR) patients is challenging and shows variability. The objective of this work was to evaluate a minimally-invasive method of direct detection of NsIgE in patients with LAR to Dermatophagoides pteronyssinus (DP) using an automated immunoassay.

Methods

Fifty patients participated (LAR, n = 14; allergic rhinitis (AR), n = 20; healthy controls [HC], n = 16). Detection of NsIgE was performed by direct application of the solid phase of a commercial DP ImmunoCAP® test 24 hours after DP nasal provocation.

Results

There was no difference in the median volume of secretion absorbed by the solid phase of the ImmunoCAP test in the 3 studied groups (p = 0.17). According to receiver operating characteristic (ROC) curve analysis, NsIgE ≥0.1450 was the optimal cutoff point, obtaining in LAR patients 42.86% sensitivity with the highest specificity (100%), and 75% sensitivity and 100% specificity for AR.

Conclusion

This study demonstrates the detection of NsIgE to DP in LAR by using a simple, commercial device with high specificity.
