Comparative outcomes for over 100 deceased donor kidney transplants from SARS-CoV-2 positive donors: A single-center experience.

Emerging data support the safety of transplantation of extra-pulmonary organs from donors with SARS-CoV-2-detection. Our center offered kidney transplantation (KT) from deceased donors (DD) with SARS-CoV-2 with and without COVID-19 as a cause of death (CoV + COD and CoV+) to consenting candidates. No pre-emptive antiviral therapies were given. We retrospectively compared outcomes to contemporaneous DDKTs with negative SARS-CoV-2 testing (CoVneg). From February 1, 2021 to January 31, 2022, there were 220 adult KTs, including 115 (52%) from 35 CoV+ and 33 CoV + COD donors. Compared to CoVneg and CoV+, CoV + COD were more often DCD (100% vs. 40% and 46%, p < .01) with longer cold ischemia times (25.2 h vs. 22.9 h and 22.2 h, p = .02). At median follow-up of 5.7 months, recipients of CoV+, CoV + COD and CoVneg kidneys had similar rates of delayed graft function (10.3%, 21.8% and 21.9%, p = .16), rejection (5.1%, 0% and 8.5%, p = .07), graft failure (1.7%, 0% and 0%, p = .35), mortality (0.9%, 0% and 3.7%; p = .29), and COVID-19 diagnoses (13.6%, 7.1%, and 15.2%, p = .33). Though follow-up was shorter, CoV + COD was associated with lower but acceptable eGFR on multivariable analysis. KT from DDs at various stages of SARS-CoV-2 infection appears safe and successful. Extended follow-up is required to assess the impact of CoV + COD donors on longer term graft function.

Utilization and outcomes of deceased donor SARS-CoV-2-positive organs for solid organ transplantation in the United States.

Coronavirus disease-19 has had a marked impact on the transplant population and processes of care for transplant centers and organ allocation. Several single-center studies have reported successful utilization of deceased donors with positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tests. Our aims were to characterize testing, organ utilization, and transplant outcomes with donor SARS-CoV-2 status in the United States. We used Scientific Registry of Transplant Recipients data from March 12, 2020 to August 31, 2021 including a custom file with SARS-CoV-2 testing data. There were 35 347 donor specimen SARS-CoV-2 tests, 77.5% upper respiratory samples, 94.6% polymerase chain reaction tests, and 1.2% SARS-CoV-2-positive tests. Donor age, gender, history of hypertension, and diabetes were similar by SARS-CoV-2 status, while positive SARS-CoV-2 donors were more likely African-American, Hispanic, and donors after cardiac death (p-values <.01). Recipient demographic characteristics were similar by donor SARS CoV-2 status. Adjusted donor kidney discard (odds ratio = 2.08, 95% confidence interval [CI] 1.66-2.61) was higher for SARS-CoV-2-positive donors while donor liver (odds ratio = 0.44, 95% CI 0.33-0.60) and heart recovery (odds ratio = 0.44, 95% CI 0.31-0.63) were significantly reduced. Overall post-transplant graft survival for kidney, liver, and heart recipients was comparable by donor SARS-CoV-2 status. Cumulatively, there has been significantly lower utilization of SARS-CoV-2 donors with no evidence of reduced recipient graft survival with variations in practice over time.

Early success transplanting kidneys from donors with new SARS-CoV-2 RNA positivity: A report of 10 cases.

Transplantation of solid organs from donors with active SARS-CoV-2 infection has been advised against due to the possibility of disease transmission to the recipient. However, with the exception of lungs, conclusive data for productive infection of transplantable organs do not exist. While such data are awaited, the organ shortage continues to claim thousands of lives each year. In this setting, we put forth a strategy to transplant otherwise healthy extrapulmonary organs from SARS-CoV-2-infected donors. We transplanted 10 kidneys from five deceased donors with new detection of SARS-CoV-2 RNA during donor evaluation in early 2021. Kidney donor profile index ranged from 3% to 56%. All organs had been turned down by multiple other centers. Without clear signs or symptoms, the veracity of timing of SARS-CoV-2 infection could not be confirmed. With 8-16 weeks of follow-up, outcomes for all 10 patients and allografts have been excellent. All have been free of signs or symptoms of donor-derived SARS-CoV-2 infection. Our findings raise important questions about the nature of SARS-CoV-2 RNA detection in potential organ donors and suggest underutilization of exceptionally good extrapulmonary organs with low risk for disease transmission.

Coronavirus disease 2019 in an orthotopic liver transplant recipient living with human immunodeficiency virus.

Coronavirus disease 2019 (COVID-19), mediated by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can manifest with flu-like illness and severe pneumonia with acute respiratory distress syndrome (ARDS). Immunocompromised patients merit particular attention as altered host immunity may influence both disease severity and duration of viral shedding as is described with several other ribonucleic acid respiratory viruses. Yet immunocompromised status alone, in the absence of other comorbidities, may not necessarily predict severe illness presentations and poorer clinical outcomes as indicated by recent reports of COVID-19-infected solid organ transplant recipients and people living with human immunodeficiency virus (HIV). Such patients may even be spared the robust inflammatory response that precipitates ARDS associated with COVID-19, complicating the management of iatrogenic immunosuppression in this setting. We present a case of an orthotopic liver transplant recipient with well-controlled HIV who successfully recovered from a mild, flu-like illness attributed to SARS-CoV-2.
