Are you an adult currently being treated for rhinosinusitis (nasal inflammation) who would like to support research into the condition? This study is collecting blood, secretion, and tissue samples from people undergoing procedures to treat long-term rhinosinusitis. Rhinosinusitis, another term for nasal inflammation, is common in people who have asthma. To participate in this study, you must be between 18 and 80 years old. This study takes place in San Francisco, California.

Are you a 30- to 55-year-old smoker or non-smoker who would like to support better understanding of COPD risk factors? This study aims to find early signs of COPD in adults who have a high risk of this condition. Researchers will compare results from questionnaires, lung tests, and other tests in people who smoke and in people who do not smoke to look for factors that predict which people will develop COPD. To participate in this study, you must either currently smoke or have no history of smoking. This study takes place in multiple locations in the United States.

Have you or your child been diagnosed with cystic fibrosis, and would you like to support better diagnosis of lung infections? This study is exploring new ways to diagnose bacterial lung infections in people who have cystic fibrosis. The study will test whether analyzing a participant’s breath and sputum samples can help diagnose infections. Participants in this study must be at least 3 years old. This study is taking place in multiple locations in the United States.

Are you a healthy adult or an adult who has been diagnosed with an interstitial lung disease (ILD)? This study will test whether administering an inhaled gas called hyperpolarized 129Xe before magnetic resonance imaging (MRI) better detects changing disease activity. To participate in the study, you must be age 18 or older and have no history of smoking for the past 5 years. This study will take place in Iowa City, Iowa; Cincinnati, Ohio; and Durham, North Carolina.

Do you or your child have primary ciliary dyskinesia (PCD)? This study aims to find out whether mild, moderate, or serious types of PCD are caused by different gene mutations. Researchers will test how well people who have various mutations, or gene changes, that cause PCD can clear mucus from their airways. Results from this study will help improve the diagnosis and treatment of PCD. This study takes place in Chapel Hill, North Carolina.

Do you or your child have PCD and want to help researchers better understand how cilia are formed? This study aims to identify the genes that control how cilia are formed. Cilia are hairlike structures that line the airways and protects the normal lung. The study will also identify how mutations to these genes can cause PCD. This study takes place in Chapel Hill, North Carolina.

Do you or your child have primary ciliary dyskinesia (PCD) or primary immune deficiency (PID)? This study aims to identify genes that cause these two conditions, which can have similar symptoms. The results from this study will help researchers find new ways to treat breathing and hearing problems caused by these two conditions in a cross-sectional cohort of patients with PCD and PID. Participants in this study must be 5 to 45 years old. This study is taking place at multiple locations in the United States and in Canada.

Do you or your child have symptoms of a serious lung disease but no diagnosis? This study aims to develop new ways to diagnose primary ciliary dyskinesia (PCD) and primary immune deficiency (PID), two conditions that can have similar symptoms. Researchers will combine information from genetic testing, lung imaging, and lung function tests to diagnose ant tell the difference between these two conditions. Participants in this study must be 5 to 45 years old. This study is taking place at multiple locations in the United States and in Canada.
