The available data on COVID-19 infection in liver transplant (LT) recipients are not conclusive and are limited to several case series. Transplant recipients are considered as “clinically extremely vulnerable” sub-population for COVID-19 because of lifelong immunosuppressive therapy and their higher rate of underlying comorbidities. We collected data from a Bulgarian liver transplant program at a single center for adult recipients of LT who were followed up from May, 2020, through May, 2022 despite the pandemic environment. The current study aims analyzing the statistically significant differences in over 50 biochemical blood parameters between cohorts of liver transplant patients with SARS-CoV-2 infection and LT patients without symptoms of infection.
