Sirolimus-induced interstitial lung disease following pediatric stem cell transplantation.

ABSTRACT

Sirolimus-induced ILD is a known but rare complication in adults who have undergone SOT. However, little is known about this adverse effect in children. Diagnosis of sirolimus-induced ILD can be challenging, especially in patients who have difficulty participating in lung function testing. We present a case of presumed sirolimus-induced ILD in a pediatric stem cell transplant patient who developed polycythemia and hypoxemia. To our knowledge, no other cases of sirolimus-induced pulmonary toxicity in children after HCT have been reported.
