Profile of Tissue Immunoglobulin E in Eosinophilic Chronic Rhinosinusitis with Nasal Polyps.

Abstract

INTRODUCTION:

Eosinophilic chronic rhinosinusitis with nasal polyps (eCRSwNP) exhibits a poorer prognosis than noneCRSwNP. The aim of this study was to analyze the potential of total immunoglobulin E (tIgE) and specific IgE (sIgE) levels in tissues for distinguishing and assessing eCRSwNP.

METHODS:

We enrolled 10 control and 88 CRSwNP patients. The clinical data of patients were collected before surgery. Nasal mucosa tissues were taken during surgery for measurements of tIgE, sIgE (weed pollen, epidermal and animal protein, mold, house dust, tree pollen), and subepithelial eosinophil (EOS) counts. The predictive significance of the potential predictors for eCRSwNP was assessed with receiver operating characteristic (ROC) curves.

RESULTS:

Nasal polyps tIgE and mold-sIgE were positively correlated with blood and tissue EOSs, comorbid allergic rhinitis and asthma, ethmoid score/total maxillary score ratio, visual analog scale, and CT score. The ROC curve analysis showed that tissue tIgE (p = 0.0004), mold-sIgE (p = 0.0030), blood EOS percentage (p = 0.0003), and absolute blood EOS count (p = 0.0010) acted as predictive factors for eCRSwNP. According to the cutoff value of tissue tIgE of 34.55 ku/L, patients with a high level were more likely to suffer from asthma (p = 0.016) and showed a significantly higher EOS count (p = 0.022), EOS percentage (p = 0.029), and tIgE (p = 0.002) in blood.

CONCLUSION:

Tissue tIgE and mold-sIgE had a significant relationship with the clinical and pathological characteristics of CRSwNP patients and might be reliable for distinguishing and assessing eCRSwNP.
