Clinical Sites

This longitudinal study is designed to define the rate of progression of PCD lung function in participants between 5-18 years of age using spirometry, which tracks well with lung impairment and prognosis in other disorders of the airways such as cystic fibrosis. This longitudinal protocol will also systematically track other specific outcomes, including pathogens infecting the airways (assessed by respiratory cultures), and age at onset and progression of airway damage and bronchiectasis (assessed by high-resolution computerized tomography, HRCT, of the chest).

This study is designed to study the way in which patients with chronic airway disease are evaluated and diagnosed. The goal of these studies is to improving diagnostic techniques, including genetic testing. In addition, clinical features (phenotype) across these disorders will be studied to better understand the disorders. This will lead not only to a better standard of clinical care, but will assist in identifying of new treatment options.

Primary Ciliary Dyskinesia (PCD) is a genetic defect in airway host-defense, and typically results in chronic infection of the airways. Patients with PCD have chronic lung, sinus and ear infections. This longitudinal study is designed to define the rate of progression of PCD lung function in participants prior to 10 years of age using special lung function tests, which helped to track lung impairment and prognosis in other disorders of the airways such as cystic fibrosis. This longitudinal protocol will also systematically track other specific outcomes, including pathogens infecting the airways (assessed by respiratory cultures), and age at onset and progression of airway damage and bronchiectasis (assessed by high-resolution computerized tomography, HRCT, of the chest).

This is an observational study of ~ 280 participants with known or suspected PCD, who will go through genetic testing for PCD. Over a 5-year period, participants who have clinical and lab features characteristic of PCD (signs that seem like PCD) will join the study. A one-time study visit is required and the visit will last about 40 minutes. In the event that follow- up is needed, you may be contacted after the first visit. The research visit will take place at one of the participating institutions. During the study, a sample of DNA will be collected for genetic testing and medical history will be reviewed.

This single-visit protocol will use a systematic approach to characterize the physical features, radiographic patterns, and associated lower airway microbial flora of adults with bronchiectasis of unknown etiology. There is no natural history of disease course follow-up component to this protocol. Participants will have one outpatient clinic visit for evaluation with a physical examination including detailed body size measurements, medical history, collection of blood samples for routine lab tests and genetic analyses, and a chest x-ray if no recent one is available. Participants will also have tests of lung function, and measurement of a gas called nitric oxide in the nose. Participants whose initial tests show abnormal results may also be asked to have a nasal scrape to collect cell samples and/or a skin sweat test to measure salt concentrations. Participants will also have a sputum specimen collected during the visit and will be asked to collect two additional early morning sputum samples and a mouth rinse at home within 2 weeks of the clinic visit, and mail the sample collection materials to the research team.
