OBJECTIVES: Dyspnea perception in asthmatics differs between subjects. Poor perception is usually associated with increased risk of asthma attack/exacerbation. The advanced stage of the disease and the presence of eosinophilic airways inflammation have been recently recognized as being responsible for poor dyspnea perception. However, few studies are available on this topic. DESIGN: The aim of this study was to analyse the influence of inflammatory pattern, age and affective status on dyspnea perception in asthmatic subjects. SUBJECTS AND INTERVENTIONS: Seventy-one consecutive asthmatic patients were recruited and underwent induced sputum, exhaled NO measurement and breath condensate collection. Perception of dyspnea was evaluated as a BORG-VAS/FEV(1) slope before and after the broncho-reversibility test and correlated with the stage of asthma, inflammatory markers, age and depression scale. RESULTS: Dyspnea perception decreases with the worsening of asthma, with the advance of age and of depression status. Furthermore, airways inflammation plays a key role in the decline of dyspnea perception as proved by the negative correlation observed between inflammatory cells in sputum, exhaled pH and NO and BORG-VAS/FEV(1) slope. CONCLUSIONS: The results of our study suggested that airways inflammation, depression status, advance age and severity of asthma influence dyspnea perception and suggest a straight control to identify and better manage poor preceptor asthmatics. |
