Clinical use of donor-derived cell-free DNA in kidney transplantation

Abstract

Traditional monitoring of kidney transplant recipients for allograft dysfunction caused by rejection involves serial checks of serum creatinine with biopsy of the renal allograft if dysfunction is suspected. This approach is labor-intensive, invasive and costly. In addition, because this approach relies on a rise in serum creatinine above historical baselines, injury to the allograft can be extensive before this rise occurs. In an effort to address this, donor-derived cell-free DNA (dd-cf DNA) is being used with increasing frequency in the clinical setting as a means of diagnosing a rejection of the renal allograft early in the course. This can potentially allow for early intervention to minimize not only injury, but the intensity of antirejection therapy needed and the avoidance of side effects. Here, we will review the available methodology for the determination and quantification of dd-cf DNA, the data supporting its use in clinical practice and the limitations of this technology.
