Abstract:

Postoperative monitoring of allograft rejection and injury in organ transplant recipients has not been effectively resolved. Cell-free DNA (cfDNA) is a fragmented and degraded DNA that can be detected in blood, urine and other body fluids. Its content in body fluids increases specifically when rejection occures or even a few weeks before the pathological diagnosis of rejection by biopsy. Donor-derived cell-free DNA (dd-cfDNA) may become a noninvasive and dynamic indicator for detecting allograft damage or acute rejection after surgery, because dd-cfDNA levels are proportional to the severity and sensitivity of injury. Studies have shown that dd-cfDNA is proportional to the severity and sensitivity of the injury. This article will review the progress of cfDNA monitoring in organ transplantation.

Key words: Cell-free DNA, Organ transplantation, Early monitoring, Dynamic indicator
