National Registry for Childhood Interstitial and Diffuse Lung Diseases

This study will collect information about children who have rare types of lung disease to help us understand how better to diagnose and treat these patients. Information will be collected from participants' doctors about how different aspects of their disease and treatment. This will be compared to information from other such patients from other hospitals around the United States. By gathering information on many such patients, we hope to develop best practices for such patients. These may lead to new research studies, which we can invite participants in this study to consider as well.
