Mammalian target of rapamycin inhibitors (mTORi), like sirolimus and everolimus, are medications used for treating certain cancers and in organ transplant procedures.
Interstitial lung disease (ILD) is a potential complication associated with mTORi, with more cases linked to sirolimus compared to everolimus, possibly due to sirolimus being more widely used earlier on.
A specific case is presented where a kidney transplant patient developed ILD from sirolimus but showed quick improvement after switching to everolimus.
