Short-term liver transplant outcomes from SARS-CoV-2 lower respiratory tract NAT positive donors

On April 2021, the United States Organ Procurement and Transplantation Executive Committee approved the “lower respiratory SARS-CoV-2 testing for lung donors” emergency policy upon recommendation from the Ad Hoc Disease Transmission Advisory Committee. This policy requires that all lung donors be tested for SARS-CoV-2 in a lower respiratory specimen by nucleic acid test (NAT) and that the results be available before the lungs are transplanted. The overarching goal of the emergency policy was to minimize the risk of donor-derived COVID-19 to lung recipients. However, an unintended consequence of the policy was the emergence of a new population of potential donors: the SARS-CoV-2 lower respiratory tract (LRT) NAT positive donor. We describe the use of two SARS-CoV-2 LRT NAT positive liver donors without a known history of COVID-19 infection with adequate short-term outcomes. The recipients did not have a prior history of COVID-19, nor did they receive monoclonal antibodies post-transplantation; one was unvaccinated. If the safety and long-term outcomes from SARS-CoV-2 LRT NAT positive donors are confirmed in larger studies, this strategy represents a promising way to increase the pool for organ donation.
