The present COVID-19 pandemic is a cause for concern among solid-organ transplant recipients, who are generally at high risk for infection and for whom infection with COVID-19 carries additional risks for complications and mortality that are higher than the COVID-19-associated risks for the general population. We report the case of a liver transplant recipient who presented with COVID-19 and multiple complications. A 39-year-old woman with a liver transplant was diagnosed with COVID-19 within the first week after transplant surgery. Mycophenolate was withheld, and interferon β was administered for management of COVID-19. She developed thrombotic thrombocyto - penic purpura, acute antibody-mediated rejection, and posterior reversible leukoencephalopathy syndrome during hospitalization. All of these complications may be related to COVID-19 or its management modalities. We considered 3 possible causes for thrombotic thrombocytopenic purpura in this patient: the COVID-19 infection itself, immuno - suppression treatment with cyclosporine, and treatment with interferon β. Immunosuppression reduction and interferon treatment may result in antibody-mediated rejection. COVID-19, thrombotic thrombocytopenic purpura, and cyclosporine may play a combined role in the development of posterior reversible leukoencephalopathy syndrome. In conclusion, thrombotic thrombocytopenic purpura, antibody-mediated rejection, and posterior reversible leukoencephalopathy syndrome may represent a continuum of 3 thrombotic microangiopathy conditions fostered by interplay between the COVID-19 infection and the treatment modalities for COVID-19 manage - ment in this patient.
