Sirolimus-induced bronchiolitis obliterans organizing pneumonia in a kidney transplant recipient; a case report and review of literature

Sirolimus is immunosuppressive drug used to prevent rejection in kidney transplantation. Pulmonary problems are one of the serious complications which may be seen after administration of this drug and it is believed that it could be life threatening. Here in this paper we presented a 49-years-old man with bronchiolitis obliterans organizing pneumonia (BOOP) induced by chronic use of Sirolimus. The disease was diagnosed and successfully treated. Sirolimus uses after kidney transplantation may lead to lung complications, especially BOOP, and the prompt diagnosis would allow earlier treatment.
