Early outcomes of kidney transplant recipients from donors with severe SARS-CoV-2 pneumonia: A report of 5 cases.

BACKGROUND: Transplanting kidneys from donors with a recent history of severe SARS-CoV-2 pneumonia is uncommon due to concerns about the risk of viral transmission and the quality of kidneys from these donors. To date, there are no conclusive data on viral transmission from extrapulmonary solid organ transplants. Given the prevalence of SARS-CoV-2 infections in potential donors, shortage of kidneys available for transplantation, and low risk of viral transmission, we developed a clinical protocol for accepting kidneys from donors with recent severe SARS-CoV-2 pneumonia who demonstrate preserved kidney function. MATERIALS AND METHODS: We collected data on early outcomes of 5 kidney transplant recipients from 4 deceased donors hospitalized for severe SARS-CoV-2 infection. RESULTS: Donor creatinine ranged from 0.51 to 0.60 mg/dL and kidney donor profile index (KDPI) from 14 to 52%. Three of the five kidneys were from donation after circulatory death. All recipients were fully vaccinated, and 4/5 received post-exposure prophylactic monoclonal antibody treatment. While 3 recipients had delayed graft function, all had excellent graft function at 3 or 4 weeks post-operatively. None of the recipients displayed signs or symptoms of SARS-CoV-2 infection post-transplant. CONCLUSION: Our findings suggest that kidney grafts from donors with a recent history of severe SARS-CoV-2 infection but with preserved kidney function can be safely used and have good early outcomes.

The dynamic treatment of SARS-CoV-2 disease.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or novel coronavirus disease 2019 (COVID-19) emerged from China in December 2019 and progressed to become a global pandemic. Our understanding of its pathophysiology and potential management was initially extrapolated from previous epidemics of coronaviruses like SARS and MERS. SARS-CoV-2 is asymptomatic or minimally symptomatic in more than 80% of patients and requires no additional management; however, the remaining patients progress to pneumonia and hypoxemia with ranging severity, including a smaller group that requires intensive care unit admission. To date, there are no approved treatments for SARS-CoV-2, and current management is focused on supplemental oxygen and supportive care. The antiviral medication remdesivir recently received emergency use authorization by the US Food and Drug Administration for patients with severe disease. Multiple clinical trials evaluating different treatment modalities such as antivirals, immunomodulators, convalescent plasma, and monoclonal antibodies, among others, are still ongoing. We believe that patients present with clinical phenotypes that correlate with the spectrum of disease. Each phenotype may benefit from one or multiple interventions. We discuss treatments under evaluation in clinical trials and their potential application based on clinical phenotype presentation.
