To investigate the most recent findings in the literature on the asthma/bronchiectasis phenotype, giving an up-to-date summary of epidemiological, clinical, and biological data connecting these two diseases. According to a growing body of literature, the combination of asthma with bronchiectasis is a common occurrence that leads to a more severe illness with frequent exacerbations. The mechanisms by which the two illnesses are related are yet unknown, however they share significant clinical and immunological characteristics as well as several comorbidities.

Early detection of bronchiectasis in patients with severe asthma using high-definition computer tomography is critical in order to offer effective therapy for both illnesses and therefore better manage symptoms, exacerbations, and infections.
