Background: The utilization of non-lung organs from deceased donors with a positive polymerase chain reaction (PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the time of donation can be lifesaving, although the safety of this policy must be assessed.
Methods: This is a nationwide, prospective study, reporting the experience on the utilization of non-lung organs from SARS-CoV-2-positive donors between December 15, 2020 and May 31, 2022 in Spain.
Results: A total of 69 patients received a solid organ transplant (41 kidney, 18 liver, 8 heart, and 2 combined liver-kidney) obtained from 32 donors with a positive SARS-CoV-2 PCR at the time of donation (four of them with a cycle threshold value <30). All recipients tested negative for SARS-CoV-2 and were free of coronavirus disease 2019 (COVID-19) symptoms prior to transplantation. Nasopharyngeal swab turned positive for SARS-CoV-2 PCR in 4 (5.8%) recipients at 3, 8, 11, and 20 days after transplantation, though evidence did not support a donor-derived COVID-19. Four kidney recipients lost their grafts and two patients died: one heart recipient due to cardiogenic shock and one combined liver-kidney recipient due to lung hypertension and right heart failure. Graft losses and patient deaths were deemed unrelated to the donor SARS-CoV-2 status by the treating teams. No other adverse reactions were reported.
Conclusions: This preliminary experience supports the safety of the use of organs other than lungs from SARS-CoV-2 PCR-positive donors, in alignment with previous series. However, the impact of SARS-CoV-2 infection upon organ quality should be established in future research.
