NIH study finds lung function remained stable or improved in adults after transplant.

So-called low-intensity blood stem cell transplants, which use milder conditioning agents than standard stem cell transplants, do not appear to damage the lungs and may help improve lung function in some patients with sickle cell disease (SCD), according to a three-year study of adults who underwent the procedure at the National Institutes of Health (NIH).

Damage to lung tissue and worsened lung function is a major complication and leading cause of death in people with sickle cell disease, a debilitating blood disorder. The new study, published today in the Annals of the American Thoracic Society, helps answer whether less intensive types of transplants, which tend to be better tolerated by many adults, by themselves either cause or promote further harm to the lungs.

“By using a low-intensity blood stem cell transplant for sickle cell disease, we may be able to stop the cycle of lung injury and prevent continued damage,” said study lead Parker Ruhl, M.D., an associate research physician and pulmonologist at NIH. “Without the ongoing injury, it’s possible that healing of lung tissue might occur, and this finding should help reassure adults living with sickle cell disease who are considering whether to have a low-intensity stem cell transplant procedure that their lung health will not be compromised by the transplant.”
