The Clinical Value of Measuring Nasal Nitric Oxide in Addition to Exhaled Nitric Oxide in Asthma Associated With Eosinophilic Chronic Rhinosinusitis
Key Points
To evaluate the clinical significance of measuring nasal nitric oxide in asthma associated with eosinophilic chronic rhinosinusitis.
Measuring nasal nitric oxide levels in patients with asthma and ECRS
Comparing nasal nitric oxide with exhaled nitric oxide
Correlation analysis with sinus CT severity
Assessment of nasal polyps and airway function
Nasal nitric oxide correlates better with ECRS disease activity than exhaled nitric oxide
Nasal nitric oxide levels are linked to the severity of sinus CT scans
Small airway dysfunction is associated with nasal nitric oxide levels
Abstract
Summary Nasal cavity NO reflects ECRS disease activity better than FeNO in patients with asthma. NC‐NO levels correlate with sinus CT severity, nasal polyps and small airway dysfunction.
