Abstract

Presentation of COVID-19 in renal transplant recipients is similar to that shown in the nonimmunocompromised population; almost all recipients who have this disease present with symptoms of the respiratory system. Acute kidney injury has been found prevalent in transplant recipients with COVID-19. In those with severe COVID-19 disease who transfer to an intensive care unit prevalence of acute kidney injury is more than 50%. The pathophysiological mechanisms of kidney involvement and the type of involvement are unclear. Here, we present a 71-year-old kidney transplant recipient who was admitted to our hospital with pulmonary and renal involvement. A kidney allograft biopsy demonstrated diffuse intrarenal hemorrhage, capillary congestion, and severe acute tubular injury. COVID-19 RNA was detected by real-time polymerase chain reaction from lysed allograft tissues, but no findings of acute or chronic cellular or antibody-mediated rejection were detected. This case indicates that COVID-19 may involve the allograft by causing hemorrhage within the renal parenchymal via direct or indirect pathways.
