Abstract：
BACKGROUND:It is essential to recognize and treat findings that can simulate or worsen symptoms to improve asthma control and thereby to reduce costs. Guidelines highlight a paranasal (PS) and chest computed tomography (CT) scan as a tool for disease evaluation and, although they suggest its indication in patients whom presentation is atypical, there are not well-defined criteria. OBJECTIVES:To describe the most common findings in the PS and chest CT in severe asthma patients and to analyse the characteristics of asthmatics with the finding of nasal polyps or bronchiectasis. METHODS:We retrospectively reviewed the medical records of 161 adults with confirmed severe asthma who had undergone to PS and/or chest CT. Clinical data from their electronic health record and the findings from a PS and/or chest CT within the last five years were collected. RESULTS:In the PS CT, 70.5% of patients presented mucous thickening and 46.7% presented nasal polyps. Both findings were associated with male gender and level of blood eosinophils. In chest CT, 28% of individuals showed atelectasis, 16.5% air trapping, 17.7% affectation of the small airway, 11.6% pulmonary infiltrates and 10.4% emphysema. Bronchiectasis were identified in 60.4% of subjects, who were older and had poorer lung function. CONCLUSION:Paranasal and thoracic computed tomography are important tools in the treatment of severe asthma because they allow us to detect highly prevalent findings in this disease that can lead to poorer control of it.
