Reduced nasal nitric oxide levels in patients with eosinophilic chronic rhinosinusitis

Allergology International, 2019
Background: In Eosinophilic chronic rhinosinusitis (ECRS), it is difficult to estimate the refractoriness and recurrence risk for each patient. Fraction of exhaled nitric oxide (FeNO) is known as a biomarker of eosinophilic inflammation in lower airway ...

In office sampling of eosinophil peroxidase to diagnose eosinophilic chronic rhinosinusitis. [PDF]

Int Forum Allergy Rhinol
AbstractBackgroundPractical biomarkers for endotypic characterization of chronic rhinosinusitis (CRS) remain elusive, hindering clinical utility. Eosinophil peroxidase (EPX) is an enzyme released by activated eosinophils. The objective of this study was to evaluate a clinic EPX assay as a marker of eosinophilic CRS.MethodsSubjects with and without CRS ...
