Kidney transplant recipients are at increased risk for infection, including coronavirus disease 2019 (COVID-19), given ongoing immunosuppression. In individuals with COVID-19, complications including thrombosis and endothelial dysfunction portend worse outcomes. In this report, we describe a kidney transplant recipient who developed severe thrombotic microangiopathy with a low platelet count (12 ×109/L), anemia (hemoglobin, 7.5 g/dL with 7% schistocytes on peripheral-blood smear), and severe acute kidney injury concurrent with COVID-19. The clinical course improved after plasma exchange. Given this presentation, we hypothesize that COVID-19 triggered thrombotic microangiopathy.
Keywords: COVID-19; acute kidney injury; kidney transplant; thrombotic microangiopathy.
