Case ReportsSirolimus-associated interstitial pneumonitis in solid organ transplant recipients.
Sirolimus is a potent immunosuppressive agent used with increasing frequency in solid organ transplantation (SOT). However, it has been associated with rare but devastating pulmonary toxicity. We describe a case of pulmonary toxicity associated with the use of sirolimus in a 64-yr-old heart transplant recipient. ⋯ Most patients (95%) resolved their clinical and radiographic findings with discontinuation or dose-reduction of the drug. Sirolimus-induced pulmonary toxicity is a rare but serious entity that should be considered in the differential diagnosis of a transplant recipient presenting with respiratory compromise. Dose-reduction or discontinuation of the drug can be life saving.
