Nasal eosinophilia and its clinical correlates in patients with allergic rhinitis at a Kenyan tertiary hospital

In this study, nasal eosinophils counts did not correlate with the severity or frequency of AR as defined by the ARIA classification. These findings suggest that while the presence of nasal eosinophilia is useful for confirming the underlying type 2 inflammation in AR, it should not be used as a standalone biomarker to determine disease severity or guide management.
