Do you or your child have pulmonary hypertension and want to help research? This study is looking to better understand pulmonary hypertension in children who have this condition. To participate in this study, you or your child must be 21 years old or younger and must have been diagnosed with pulmonary hypertension before the age of 18. This study is located at multiple sites across the United States and Canada, including California, Colorado, Massachusetts, New York, Pennsylvania, Tennessee, and Alberta, Canada.

Are you scheduled for a stem cell transplant with cord blood? This study will assess the safety and effectiveness of certain cord blood transplants. The study will help researchers learn the best methods for collecting, storing, and using cord blood in transplants. To participate in this study, you must have a disorder that compromises your body’s ability to make blood cells. This study is located in Bethesda, Maryland.

Do you know a newborn or toddler who has severe combined immunodeficiency? This study will test the safety and effectiveness of genetic therapies to treat X-linked severe combined immunodeficiency (SCID-X1), a rare genetic immune disorder. The therapies could be a new approach to treat SCID-X1 in people who do not have a brother or sister to be a donor for stem cell transplant. To participate in this study, the child must be 2 years old or younger. This study is located in Memphis, Tennessee; San Francisco, California; and Seattle, Washington.

Do you have sickle cell disease or thalassemia, or are you a healthy volunteer who is willing to undergo a brain MRI? This study aims to understand whether sickle cell disease or thalassemia affects the processes that naturally increase blood flow in the brain when people experience stress. Researchers will measure blood flow using brain magnetic resonance imaging (MRI). Participants in this study must be at least 7 years old and have sickle cell disease or thalassemia. Healthy volunteers can also participate. This study is located in Los Angeles, California.

Is your child on a ventilator at Children’s Hospital Los Angeles? Ventilators can sometimes weaken the muscles around the lungs, especially in children. This study is testing whether a new computer method to control ventilators can help prevent muscle weakness in children. To participate in this study, your child must be between 1 month and 18 years old and have been on a ventilator for less than 48 hours (or 72 if they were transferred from another hospital) because of a serious lung disease. This study is located in Los Angeles, California.

Do you have symptoms of a lung disease (such as long-term wet cough, bronchiectasis, or recurrent pneumonia) with no genetic diagnosis? This study aims to develop new ways to diagnose primary ciliary dyskinesia (PCD) or 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 and tell the difference between these two conditions. Participants in this study must be 5 to 45 years old and must have symptoms of a serious lung disease but no diagnosis. This study is taking place at multiple locations in the United States and in Canada, including the NIH Clinical Center in Bethesda, Maryland.

Are you or your child between the ages of 3 and 21 and experiencing pain episodes? This study tests a treatment called arginine therapy for pain episodes in children with sickle cell disease. Researchers are investigating how safe and effective this treatment is, as well as how arginine is metabolized in the body and its effects on cells. To participate in this study, you or your child must have sickle cell disease and pain that requires medical attention. This study takes place in multiple locations in the United States.

Do you know a child with Kawasaki disease-related coronary artery abnormalities? This study is testing whether a combination of two medicines—atorvastatin and anakinra—can effectively treat a type of vasculitis called Kawasaki disease, which most often affects children. Participants in this study must be 1 to 17 years old and diagnosed with Kawasaki disease. This study takes place in San Diego, California.

Do you or your child have asthma and want to help researchers better understand the disease? This study examines the molecular components of asthma to better understand how long-term mild to severe asthma affects children and adults. Researchers hope to use findings to develop new asthma treatments. To participate in this study, you or your child must be 6 years old or older. This study takes place in multiple locations in the United States.
