Examining the airway epithelium in children with post-infectious bronchiolitis obliterans
This study is trying to see if there are differences in the nose lining of young children who get sick from certain viruses and later develop post-infectious bronchiolitis obliterans compared to those who don’t.
-
Using belumosudil to prevent or treat bronchiolitis obliterans in stem cell transplant patients
This study is testing if a new medication called belumosudil can help prevent or treat bronchiolitis obliterans in patients who have recently had a stem cell transplant.
-
Investigating abnormal cells in patients with bronchiolitis obliterans syndrome
This study is testing whether looking at certain abnormal cells in the blood and lungs of patients with bronchiolitis obliterans syndrome after a transplant can help doctors find this condition earlier.
-
Long-term observation of lung injury in children after stem cell transplants
This study looks at children who have had stem cell transplants to see how often they develop lung problems and how these issues affect their health over time.
