Abstract
Chronic immunosuppression is associated with an increased risk of opportunistic infections. Although kidney transplant recipients with coronavirus disease 2019 (COVID-19) have higher mortality than the general population, data on their risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are unknown. Subject of Review: A recent single-center screening study from the UK (Transplantation. 2021 Jan 1;105(1):151-7) showed that 89 (10.4%) of 855 consecutive kidney transplant recipients tested positive for SARS-CoV-2 antibodies. Risk factors for infection included a nonwhite background, diabetes, and a history of allograft rejection. Risk factors for mortality in individuals who developed COVID-19 were older age and receiving steroids. Second Opinion: This study shows that the rate of SARS-CoV-2 infection in kidney transplant recipients is similar to the one observed in the general population in the same area (13%), indicating that transplant recipients are not at increased risk of COVID-19. However, the investigators raise the interesting point that since transplant individuals were advised to shelter earlier than the general population, they may be in fact more susceptible. This statement is hard to substantiate, but the identification of specific risk factors for infection and poor outcomes is crucial to tailor strategies to prevent spread of the infection. This is particularly important, considering that kidney transplant recipients may be at increased risk of prolonged viral spread and in-host viral mutations, making them not just a particularly fragile population for COVID-19 but also a potentially major source of further contagions.
