Clinical Trial Summary
There is an intricate link between bronchiectasis and fungi. Patients with cystic fibrosis
frequently manifest fungal sensitization and fungal colonization with Aspergillus fumigatus.6
Aspergillus species also has a cause-and-effect relationship with non-CF (cystic fibrosis)
bronchiectasis.7, 8 In allergic bronchopulmonary aspergillosis (ABPA), Aspergillus is the
cause of bronchiectasis. In contrast, in other causes of bronchiectasis, A fumigatus can
theoretically promote allergic response, which may result in poor lung function, increase the
risk of exacerbations, and even cause ABPA over time.9, 10 In a recent study, we found an
overall prevalence of Aspergillus sensitization of 29.5% and the prevalence of chronic
aspergillus infection was 76%.11 The prevalence of chronic aspergillus colonization in
non-(tuberculosis) TB-non-CF fibrosis was 47.5% (49/103).11 By mechanism similar to chronic
bacterial colonization, chronic aspergillus infection or aspergillus sensitization can
increase the risk of bronchiectasis exacerbation. Therefore, eradication of A. fumigatus from
the airways of patients with bronchiectasis would decrease the future risk of a
bronchiectasis exacerbation. Notably, in ABPA, use of itraconazole and voriconazole reduce
the exacerbations by reducing the fungal burden in the airways.12, 13 In this randomized
trial, we will investigate whether treatment with oral itraconazole for six months would
reduce the future risk of bronchiectasis exacerbation in patients with non-CF-non-ABPA
bronchiectasis.
Description:
Bronchiectasis is a chronic lung disease due to irreversible and abnormal dilatation of the
bronchi. Bronchiectasis manifest with chronic cough, expectoration, hemoptysis, dyspnea, and
others. Bronchiectasis can be broadly classified as genetic (cystic fibrosis [CF], ciliary
dyskinesia and others) or acquired (post-infective, tuberculosis (TB), allergic
bronchopulmonary aspergillosis [ABPA] and others).1 The natural course of bronchiectasis is
associated with recurrent exacerbations that cause further damage and disease progression.2
Most exacerbations are caused by viral or bacterial infections, inflammation and external
environment factors. Chronic bacterial infections increase the risk of bronchiectasis
exacerbation.2 In a multicentric European study chronic infection with Pseudomonas aeruginosa
was associated with an increased risk of exacerbation.3 Notably, change in the interaction
between the bacterial microbiome by external inciting events (viral infection or air
pollution) increases exacerbation risk.4 Similarly, viral infections by increasing the
systemic and airway inflammation induce a bronchiectasis exacerbation.5 Airway inflammation
both neutrophilic and eosinophilic are also important causes of bronchiectasis
exacerbations.2 Most previous studies in non-CF bronchiectasis have not investigated the role
of fungal sensitization or chronic fungal infection in causing bronchiectasis exacerbation.

Study question: Does oral itraconazole for six months reduce the bronchiectasis exacerbation
in patients with non-cystic fibrosis bronchiectasis?
