Extract

Similar to patients with cystic fibrosis (CF) and non-CF bronchiectasis, patients with primary ciliary dyskinesia (PCD) are prone to recurrent or chronic lung infections with Pseudomonas aeruginosa (Pa). Chronic Pa lung infection has a prevalence of up to 39% in patients with PCD [1] and is associated with structural damage affecting lung function. Treatment of Pa infection is challenging because Pa adapts to the host environment through genotypic/phenotypic changes, promoting a reduced immune response [2]. We have previously found that the paranasal sinuses in patients with CF act as bacterial reservoirs where Pa adapts and recolonises Pa-eradicated lungs [3, 4]. Our group has also reported Pa positive cultures from the upper and lower airways, of patients with PCD [5]. However, it was unclear whether the paranasal sinuses of patients with PCD also act as bacterial reservoirs. We are investigating whether the same Pa clone type colonises both the paranasal sinuses and the lungs, and the extent to which Pa adapts to the host environment via genotypic/phenotypic changes.
