Do you know someone whose child was just born preterm? This study aims to understand why some premature babies have low blood pressure by studying heart and lung changes during the first week of life in preterm babies who do or do not have low blood pressure. Researchers hope the results will improve monitoring of newborns’ blood circulation patterns. To participate in this study, your newborn must have weighed 2.2 pounds or less at birth, be less than 1 week old, and be receiving care in a neonatal intensive care unit. This study is located in Houston, Texas.

El objetivo de este estudio es comprender por qué algunos bebés prematuros tienen baja presión arterial mediante el estudio de los cambios en el corazón y los pulmones durante la primera semana de vida en los bebés prematuros que tienen presión arterial baja o no. Los investigadores esperan que los resultados mejoren el monitoreo de los patrones de circulación sanguínea de los recién nacidos. Para participar en este estudio, su recién nacido debe haber pesado 1 kilogramo (2,2 libras) o menos en el nacimiento, tener menos de 1 semana de edad y estar recibiendo atención en una unidad de cuidados intensivos neonatales. Este estudio se lleva a cabo en Houston (Texas).

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 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.
