Severe asthma and bronchiectasis.

The aim of our study was to determine the tomographic findings and prevalence of bronchiectasis in our population of patients with severe asthma, and to identify factors associated with the presence of bronchiectasis in these patients. We retrospectively collected data from the medical histories of patients referred to the asthma unit of our hospital, with a diagnosis of severe asthma between 2015 and 2017. Patients with ABPA, cystic fibrosis, immunodeficiency or systemic disease were excluded.
