- BACKGROUND: We have reported that increased fraction of exhaled nitric oxide (FeNO), a measure of TH2 -driven airway inflammation, and blood eosinophil count, a marker of systemic eosinophil inflammation, correlated with asthma attacks in a population-based study.OBJECTIVE: To investigate the relation between simultaneously elevated FeNO and serum eosinophil cationic protein (S-ECP) levels and asthma events among asthmatics.METHODS: Measurements of FeNO (elevated ≥ 25 ppb) and S-ECP (elevated ≥ 20 ng/mL) were done in 339 adult asthmatics. Asthma events (attacks and symptoms) were self-reported.RESULTS: Simultaneously normal S-ECP and FeNO levels were found in 48% of the subjects. Subjects with simultaneously elevated S-ECP and FeNO (13% of the population) had a higher prevalence of asthma attacks in the preceding 3 months than subjects with normal S-ECP and FeNO (51% vs. 25%, p = 0.001). This was not found for subjects with singly elevated S-ECP (p = 0.14) or FeNO (p = 0.34) levels. Elevated S-ECP and FeNO levels was independently associated to asthma attacks in the preceding 3 months after adjusting for potential confounders (OR (95% CI) 4.2 (2.0-8.8).CONCLUSIONS: Simultaneous elevated FeNO and S-ECP related to a higher likelihood of asthma attacks in the preceding 3 months. This indicates that there is a value in measuring both FeNO and systemic eosinophilic inflammation in patients with asthma in order to identify individuals at high risk of exacerbations.
