COVID-19 and short and medium-term outcomes in liver transplant patients: A spanish single-center case series

Background & aims The evidence suggests that most vulnerable subjects to COVID-19 infection suffer from patients with comorbidities or immunosuppression, including liver transplant recipients. Liver graft dysfunction may be a rare complication. Some patients complain about the post-COVID-19 syndrome. The aim of this study was to assess medium- and short-term outcomes in liver transplant patients. Patients and methods A retrospective case series was performed at a tertiary referral center. We screened 845 patients who had liver transplant (LT) in our center. All consecutive LT patients with COVID-19 during the Spanish outbreak from March 2020 to April 2021 were included. Demographics, pre-existing comorbidities, clinical and radiological data of COVID-19 infection, complications, and liver graft function were assessed at diagnosis and 3-month follow-up. Results Overall, 20 LT patients were diagnosed with confirmed COVID-19. We included 16 patients that met the inclusion criteria, 8 nonhospitalized (50%) and 8 (50%) hospitalized patients were analyzed. The median follow-up was 5.33 months (IQR 3.06–8.26). One patient died during the follow-up. All patients presented some grade of respiratory or functional symptoms. Dyspnea and fatigue were the most prevalent symptoms during the 3-month follow-up. No liver graft dysfunction were reported despite of partial immunosuppression withdrawal in four patients (25%). One patient had cardiovascular complications. Conclusions Our results suggest the presence of post-COVID-19 syndrome with mild residual physical and psychological dysfunction in this subgroup of patients at 3 months after COVID-19. However, no cases of loss or liver graft dysfunction were reported.
