Studies on coronavirus disease-2019 outcome and mortality in liver transplant recipients

Study Numbers of LT Recipients with SARS-CoV-2 Infection Country Findings
Rabiee A, et al,95 2020 112 United States
  • Mortality 22.3%

  • Moderate liver injury (ALT 2-5x ULN) 22.2%, severe liver injury

  • (ALT > 5× ULN) 12.3%

  • Liver injury in LT recipients was associated with mortality (P = .007; OR = 6.91) and ICU admission (P = .007; OR = 7.93)

  • Reduction of immunosuppression during COVID-19 was not associated with mortality (P = .084)

Colmenero J, et al,64 2021 (SETH registry) 111 Spain
  • Mortality 18%, severe COVID-19 31.5%

  • LT patients had an increased risk of acquiring COVID-19 but their mortality was lower than the matched general population

  • Mycophenolate may increase the risk of severe COVID-19 in a dose-dependent manner

Kates OS, et al,96 2021 73 United States
  • The 28-d mortality among solid organ transplant cohort (n = 482 hospitalized with COVID-19) was 20.5%

  • LT was not associated with increased 28-d mortality (P = .36)

Ravanan R, et al,97 2020 (UK National Health Service Blood and Transplant registry) 64 England
  • SOT recipients with SARS-CoV-2 infection had a higher all-cause mortality compared with wait-listed patients (25.8% vs 10.2%)

  • LT recipients had a lower SARS-CoV-2 infection rate than other SOT recipients (OR = 0.53, 95%CI 0.40–0.70)

Webb GJ, et al,65 2020 (SECURE-cirrhosis and COVID-Hep) 151 International registry
  • Overall mortality was 18.5%

  • LT did not significantly increase the risk of death

  • Age, high creatinine level, and nonliver cancer were associated with mortality among LT recipients

Belli LS, et al,66 2021 (ELITA/ELTR COVID-19 registry) 243 Europe
  • Mortality 20.2%, respiratory failure was the major cause of death

  • Older age, diabetes, and chronic kidney disease were associated with mortality

  • Tacrolimus use (HR = 0.55, 95%CI 0.31–0.99) had a positive independent effect on survival

Polak WG, et al,98 2020 (ELITA/ELTR COVID-19 registry) 57 SARS-CoV-2–infected LT candidates
272 SARS-CoV-2–infected LT recipients
Europe
  • Incidence of COVID-19 among LT candidates was 1.05% and LT recipients 0.34%

  • Mortality was 18% among LT candidates and 15% among LT recipients

Abbreviations: HR, hazard ratio; LT, liver transplant; N, number of patients; SOT, solid organ transplant.
