Bronchiectasis is a chronic irreversible airway abnormality associated with infectious agents that either cause or superinfect the airways. While the role of bacteria is well studied, much remains to be determined about fungi in both cystic fibrosis- and non-cystic fibrosis-related bronchiectasis. The airway is constantly exposed to inhaled ambient moulds of which Aspergillus represent the most ubiquitous. ⋯ How transition occurs between allergic and invasive phenotypes and their respective biomarkers is also important. Whether anti-fungal treatment is warranted in all cases and what the optimal management strategy is, particularly when treatment should commence and its expected duration remains unclear. Further research is clearly necessary and should be prioritized to better understand the clinical effects and impact of Aspergillus in the setting of bronchiectasis.

Aspergillus fumigatus frequently colonizes the airways of patients with cystic fibrosis (CF) and may cause various severe infections, such as bronchitis. Serological data, sputum dependent markers and longitudinal data of treated cases of Aspergillus bronchitis were evaluated for further description of this infection. This study, which comprises three substudies, aimed to analyze epidemiological data of Aspergillus in CF and the entity of Aspergillus bronchitis. ⋯ A prevalence of 9% was assessed. Aspergillus bronchitis appears to occur in a minority of colonized CF patients. Antifungal treatment may reduce respiratory symptoms and restore lung function.
