The purpose of this study is to help determine how often primary ciliary dyskinesia (PCD) is present but undiagnosed in adults with bronchiectasis.
Bronchiectasis is a chronic respiratory disease characterized by irreversible bronchial dilatation, impaired mucociliary clearance, and recurrent infection. Despite comprehensive evaluation, 40-80% of adults with non-cystic fibrosis (CF) bronchiectasis have no identifiable cause. This diagnostic absence limits opportunities for targeted therapy, individualized prognostication, and potential genetic counseling. Primary ciliary dyskinesia (PCD) is an inherited disorder of motile cilia that leads to chronic otosinopulmonary disease. Nearly 100% of affected individuals develop bronchiectasis by a…
