Early Experience Using Donor-derived Cell-free DNA for Surveillance of Rejection Following Simultaneous Pancreas and Kidney Transplantation.

ABSTRACT:

Background

Allograft biopsy is the gold standard for diagnosing graft rejection following simultaneous pancreas and kidney (SPK) transplant. Intraperitoneal biopsies are technically challenging and can be burdensome to patients and the healthcare system. Donor-derived cell-free DNA (dd-cfDNA) is well-studied in kidney transplant recipients; however, it has not yet been studied in the SPK population.

Methods

We hypothesized that dd-cfDNA could be utilized for rejection surveillance following SPK transplant. We prospectively collected dd-cfDNA in 46 SPK patients at a single institution.

Results

There were 10 rejection events, 5 of which were confirmed with biopsy. The other 5 were treated based on dd-cfDNA and clinical data alone with favorable outcomes. Among all patie
