Abstract:

The occurrence of postoperative lung transplantaion complications severely affect the patient's quality of life and prognosis. Accurate diagnosis of allograft rejection and pulmonary infection is crucial for the treatment and outcome of patients. Traditional histopathological examination by lung biopsies is the gold standard for the diagnosis of rejection, but it has drawbacks such as invasiveness,low positivity rate, high operational difficulty, and delayed results. Cell-free DNA in plasma,especially donor-derived cell-free DNA (dd-cfDNA), as a sensitive biomarker, has been increasingly used for monitoring rejection after solid organ transplantation such as kidney and liver transplantation.This article reviews application value of dd-cfDNA as an potential tool for post-transplant management,in the management of complications after lung transplantation.

Key words: Donor-derived cell-free DNA, Lung transplantation, Allograft rejection, Pulmonary infection
