COVID-19 progression in kidney transplant recipients: A single-center case series

Abstract

The novel coronavirus disease 2019 (COVID-19) is a respiratory infection that has received much attention due to its rapid expansion. Currently, it has been revealed that patients with underlying disease, especially those with kidney disease are more prone to develop complications. Some studies associate kidney transplantation as a risk factor for COVID-19 progression; however, epidemiologic data that demonstrate this are amazingly rare. Considering the importance of the topic, we report on six kidney transplant recipients (median age 47 [41-55]) with confirmed or clinically suspected COVID-19. The most common admission presentations were fever (83.3%), dyspnea, and myalgia. At baseline, immunosuppressive therapy was ceased, prednisolone dose was increased, and all patients received antiviral treatment including hydroxychloroquine and umifenovir. After a median follow-up of 11.5 days from admission, six patients (100%) developed acute kidney injury (AKI), 50% required intensive care unit (ICU) admission, and two patients (33.3%) deceased as a result of deterioration in respiratory status. Overall, these findings demonstrate that AKI development and respiratory involvement may be risk indicators of in-hospital mortality in kidney recipients with COVID-19. Therefore, more intensive attention should be paid to kidney transplant recipients with COVID-19.
