Do you or your child have a lung disease? This study will investigate the genes involved in the breathing process and in the development of lung diseases such as asthma or sarcoidosis to improve understanding of the role they play. To participate in this study, you or your child must be between 2 and 90 years old. This study is located in Bethesda, Maryland, at the NIH Clinical Center.

Do you have chronic bronchitis and COPD and want to improve treatment? This study will be testing how well a medicine called ivacaftor that is used to treat cystic fibrosis works also to treat symptoms of chronic bronchitis. New research suggests chronic bronchitis may be due to a problem similar to cystic fibrosis. To participate in this study, you must be 40 to 80 years old, have a history of smoking, and have not been diagnosed with asthma or cystic fibrosis. This study will be conducted in Birmingham, Alabama.

Do you have COPD? This study will be looking for genes that may play a role in the development of COPD by looking at the blood from patients who have COPD, as well as the blood from those patients’ family members. To participate in this study, you must be 52 years old or younger and must not be pregnant or have other serious lung diseases such as lung cancer. This study will be conducted in Boston, Massachusetts.

Are you an adult with a lung disease such as COPD, chronic bronchitis, cystic fibrosis, or emphysema? This study aims to discover if low-dose computed tomography (CT) scans are as effective as regular CT scans in monitoring your COPD. This study is located in Bethesda, Maryland, at the NIH Clinical Center.

Do you have COPD, or are you a healthy volunteer who is willing to do an imaging test? This study will use an imaging test called single-photon emission computed tomography (SPECT) to compare the lung function of patients who have COPD with healthy volunteers who smoke and who do not smoke. The CT scan can detect death of cells in a process called apoptosis, which is linked to severe COPD and cannot be seen in the normal adult lung. To participate in this study, you must be at least 18 years old and either have moderate to severe COPD, not have COPD and be a smoker for longer than 10 years, or not have COPD and never smoked. This study is located in New York, New York.

Do you have asthma, COPD, or asthma COPD overlap syndrome? This study will look at whether a health coach can help people who have asthma, COPD, or asthma-COPD overlap syndrome with their condition. You will be randomly selected to meet with either a lung specialist alone or a lung specialist and a health coach, who will give you recommendations to improve your care and better manage your condition. To participate in this study, you must be age 18 or older, have asthma or COPD, and not already be seeing a lung specialist. You also must get your care from one of 10 health centers in San Francisco, California. This study is located in San Francisco, California.

Do you or your child have a platelet, bleeding, or white blood cell disorder? This study is looking at people who have platelet or other blood disorders. The researchers will use a blood sample to look for problems with platelets and a possible genetic cause in the participant’s DNA or RNA. To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. This study is located in New York, New York.

Does your infant have a low platelet count? This study is investigating the safety and efficacy of platelet transfusion as a treatment for infants with thrombocytopenia. Researchers are looking at the positive effects of platelet transfusion against the negative effects, such as the release of inflammatory molecules and the formation of blood clots. To participate in this study, your child must be younger than 6 months old and have a low platelet count (less than 100 × 109/L). This study takes place in Boston, Massachusetts.

Does your infant have a low platelet count? This study investigates immature platelet counts as a marker for bleeding risk in newborns with thrombocytopenia, compared with platelet counts alone. Immature platelets are the most recently produced platelets and may be a better marker of platelet production. To participate in this study, you must have a newborn who is less than 32 weeks’ gestational age, has a birth weight greater than 500 grams, and has a platelet count less than 100 × 109/L. This study takes place in multiple locations in the United States, the Netherlands, and Sweden.

Are you an adult with polycythemia vera or thrombocytosis? This study aims to find a new treatment or cure for polycythemia vera and thrombocytosis by locating genes and their changes, or mutations, that may contribute to these disorders. To participate in this study, you must have polycythemia vera with elevated hemoglobin (higher than 18 in men and 16 in women) or thrombocytosis with an elevated platelet count (higher than 450,000). This study takes place in Salt Lake City, Utah.
