Background: The COVID-19 pandemic has negatively impacted organ donation and transplantation across the globe. Methods: This study analyzed transplant outcomes during the pre-pandemic [PPE, 1/2019-2/2020] and pandemic era [PE, 3/2020-8/2020] based on changes in induction immunosuppression. During PPE, high immunological risk patients received 4-6 mg/kg, moderate risk 2-4 mg/kg, and low risk 1-2 mg/kg of ATG. During PE, ATG doses were reduced to 3-4 mg/kg for high risk, 1-2 mg/kg for moderate, and low changed to basiliximab. Primary outcomes are as follows: biopsy-proven rejection [BPAR], de-novo donor-specific antibody [DSA], delayed graft function [DGF], infection rates, graft loss, and all-cause of mortality.
Background. There is limited documentation of hematogenous transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in non–lung transplants from infected donors to uninfected recipients. Methods. We analyzed 16 recipients (7 liver, 9 kidney) transplanted from SARS-CoV-2 nucleic acid test+ deceased donors from December 25, 2021, to February 28, 2022, who were followed-up for at least 90 d. Primary outcomes included coronavirus disease 2019–positivity, allograft loss, and all-cause mortality. Secondary outcomes included biopsy-proven rejection (BPAR), donor-specific antibodies, delayed graft function, and opportunistic infections. Unlike previous studies, we followed the recipients clinically with the intent to treat if they developed SARS-CoV-2 symptoms. Results. All donors were SARS-CoV-2 polymerase chain reaction–positive 72 h before donation. No recipients developed SARS-CoV-2 infection. The nadir serum creatinine and estimated glomerular filtration rate were 1.33 mg/dL and 64 mL/min/1.732 m2 for kidney transplantation (KTx) respectively. The median alanine transaminase was 14.5 IU/L, aspartate aminotransferase 13 IU/L, and alkaline phosphatase 74 IU/L. Two KTx patients lost allograft, and 1 liver transplantation patient died with a failed allograft. However, this was unrelated to their SARS-CoV-2–positive donor status. One BPAR in the liver transplantation was treated with steroids. No donor-specific antibodies or BPAR were reported in the KTx. Six KTx patients experienced delayed graft function, and 4 are off dialysis. Two KTx patients developed cytomegalovirus infection because of an error in reporting the cytomegalovirus serostatus by the donor center. We did not do serial testing for SARS-CoV-2 by polymerase chain reaction, imaging, or cycle threshold score pre- or posttransplant for donor/recipient and had comparable outcomes with previous studies. Conclusions. Because of the low risk of transmission, serial testing might not be necessary and, thus, could be reciprocated at small-volume transplant centers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
