BACKGROUND
Several severe asthma comorbidities have been identified: an emerging one is bronchiectasis. We evaluated the frequency of bronchiectasis on severe asthma in a real-life setting, through the 'Severe Asthma Network Italy' (SANI) registry.
METHODS
SANI registry encompasses demographic, clinical, functional and inflammatory data of Italian severe asthmatics. Data obtained by the enrolled patients were analyzed, focusing the attention on those patients with concomitant clinically relevant bronchiectasis.
RESULTS
About 15.5% patients have bronchiectasis. Bronchiectasis diagnosis was associated with a higher prevalence of chronic rhinosinusitis with nasal polyps (54.6% vs. 38%, p = 0.001) and higher serum IgE levels (673.4 vs. 412.1 kUI/L, p = 0.013). Patients with bronchiectasis had worse asthma control (ACT: 16.7 vs 18.2, p = 0.013), worse quality of life (AQLQ: 4.08 vs. 4.60, p = 0.02) and lower lung function (FEV
CONCLUSION
severe asthma associated with bronchiectasis represents a particularly severe asthma variant, possibly driven by an eosinophilic endotype. We, therefore, suggest that bronchiectasis should necessarily be assessed in severe asthmatic patients.
