Early outcomes of lung transplantation with lung allografts from coronavirus disease 2019 (COVID-19)-positive donors

Abstract

Objective: Coronavirus disease 2019 (COVID-19) can be detected for extended periods of time with nucleic acid amplification test even after transmissibility becomes negligible. Lung allografts from COVID-19-positive donors have been used for transplantation in highly selected cases. This study aimed to clarify the early outcomes of lung transplantation with COVID-19-positive donors.

Methods: The Organ Procurement and Transplantation Network/United Network for Organ Sharing database between April 2020 and June 2022 was retrospectively analyzed.

Results: In the study period, 1297 COVID-19-positive donors were identified and the lungs were transplanted from 47 donors (3.6%). Of 47 donors, 44 donors were positive for COVID-19 NAT with nasopharyngeal swabs and the other 3 were positive with bronchoalveolar lavage. The COVID-19-positive lung donors were younger than the COVID-19-negative donors (28.4 ± 11.6 years vs 35.4 ± 13.6 years, P < .001). Recipients of the COVID-19-positive lungs (n = 47) were more likely have a greater lung allocation score (57.1 ± 22.9 vs 50.5 ± 19.7, P = .057) than recipients of COVID-19-negative lungs (n = 5501). The posttransplant length of hospital stay (39.8 ± 43.6 days vs 30.6 ± 34.5 days, P = .181), need for extracorporeal membrane oxygenation support at 72 hours after transplantation (2.6% [1/38] vs 10.4% [541/5184], P = .18), and 1-year overall survival rate (85.6% vs 87.1%, P = .63) were comparable between the 2 groups.

Conclusions: Carefully selected lung allografts from COVID-19-positive donors had comparable early posttransplant outcomes to lung allografts from COVID-19-negative donors.
