BACKGROUND Kidney transplant recipients have higher risk of infectious diseases due to their reliance on immunosuppression. During the current COVID-19 pandemic, some clinicians might have opted for less potent immunosuppressive agents to counterbalance the novel infectious risk. We conducted a nationwide study to characterize immunosuppression use and subsequent clinical outcomes during the first 5 months of COVID-19 pandemic in the United States. METHODS Using data from the Scientific Registry of Transplant Recipients, we studied all kidney-only recipients in the United States from 1/1/2017 to 3/12/2020 (\'prepandemic\' era; n=64 849) and from 3/13/2020 to 7/31/2020 (\'pandemic\' era; n=5035). We compared the use of lymphocyte-depleting agents (vs. basiliximab or no induction) and maintenance steroids (vs. steroid avoidance/withdrawal) in the pandemic era compared to the prepandemic era. Then, we compared early posttransplant outcomes by immunosuppression regimen during the pandemic era. RESULTS Recipients in the pandemic era were substantially less likely to receive lymphocyte-depleting induction agents compared to their prepandemic counterparts (aOR=0.400.530.69); similar trends were found across subgroups of state-level COVID-19 incidence, donor type, and recipient age. However, lymphocyte-depleting induction agents were associated with decreased rejection during admission (aOR=0.110.230.47), but not with increased mortality in the pandemic era (aHR=0.130.471.66). On the other hand, the use of maintenance steroids versus early steroid withdrawal remained similar (aOR=0.711.071.62). CONCLUSIONS The use of lymphocyte-depleting induction agents has decreased in favor of basiliximab and no induction during the COVID-19 pandemic. However, this shift might have resulted in increases in rejection with no clear reductions in posttransplant mortality.
