Abstract

Abstract : Background: Solid organ transplant recipients (SOTr) are at increased risk for severe disease from coronavirus disease 2019 (COVID-19) compared with non-SOTr. Methods: We performed a retrospective cohort study between March 1, 2020, and March, 30, 2021, in an integrated healthcare system with 4.3 million members aged ≥18 y including 5126 SOTr. Comparisons in COVID-19 mortality, hospitalization, and incidence were made between SOTr and non-SOTr, and between different SOTr organs. Multivariate analysis was performed to identify risk factors for COVID-19 mortality and hospitalization. Results: There were 600 SOTr (kidney, liver, heart, and lung) with COVID-19. Per person-year incidence of COVID-19 among SOTr was 10.0% versus 7.6% among non-SOTr ( P < 0.0001). Compared with uninfected SOTr, infected SOTr were older (57.1 ± 14.0 versus 45.7 ± 17.9 y, P < 0.001), predominantly Hispanic/Latino (58.8% versus 38.6%, P < 0.0001), hypertensive (77.0% versus 23.8%; P < 0.0001), and diabetic (49.6% versus 13.0%; P = 0.0009). Compared with non-SOTr, infected SOTr had higher hospitalization (39.5% versus 6.0%; P < 0.0001), intensive care unit admission (29.1% versus 15.5%; P < 0.0001), and mortality (14.7% versus 1.8%; P < 0.0001) from COVID-19. Older age (hazard ratio [HR], 1.07; 95% confidence interval [CI], 1.05-1.10), male gender (HR, 1.79; 95% CI, 1.11-2.86), and higher body mass index (HR, 1.04; 95% CI, 1.00-1.09; P = 0.047) were associated with increased mortality from COVID-19, whereas race, diabetes, and number/type of immunosuppressive medications were not. Among the different SOTr, COVID-19 mortality risk was lowest in liver recipients (HR, 0.34; 95% CI, 0.16-0.73) and highest in lung recipients (HR, 1.74; 95% CI, 0.68-4.42). Conclusions: SOTr have higher rates of hospitalization and mortality from COVID-19 compared with the general population. Among the SOTr, the incidence and outcomes were distinct among different transplantation types.
