Abstract

Background And Aim: Patients who have undergone solid organ transplantation are at an elevated risk of severe coronavirus disease (COVID-19) because of post-transplantation immunosuppressive therapy. However, optimization of vaccination, modification of immunosuppression, and implementation of monoclonal antibody (mAb) therapy in transplant recipients with COVID-19 is uncertain.

Methods: A retrospective cross-sectional study was conducted on patients who underwent liver or kidney transplants and were diagnosed with COVID-19. The association of several vaccine doses, mycophenolate therapy, and mAB therapy with mortality outcomes after COVID-19 diagnosis (3 and 6 months), hospitalization, and length of hospital stay were assessed.

Results: This study included 255 patients with a median age of 59 (23-89) were included. Many COVID-19 vaccine doses were not associated with any outcome; however, patients with a liver transplanted with mycophenolate had higher 3-month (19% vs. 0%;  = 0.02) and 6-month (21% vs. 0%;  = 0.01) mortality rates than those who did not. In addition, transplant recipients who received mAb therapy for COVID-19 were less likely to be hospitalized (37% vs. 68%;  < 0.001).

Conclusions: For organ transplant recipients with COVID-19, vaccination alone may not be an optimal strategy for preventing serious outcomes. Rather, the types of organ transplant, immunosuppressive therapy (particularly mycophenolate), and COVID-19 treatment strategy should be synergistically considered to promote an optimal therapeutic dynamic for a vulnerable population.
