Uludağ University School of Medicine, Dept of General Surgery, Bursa, Turkey Introduction Results The effect of coronavirus disease 2019 (COVID-19) on outcomes of liver transplant A total of 129 liver transplant recipient had diagnosed with COVID-19. Median age was 56 years. The recipients recipients is not known very well. were predominantly male (69%). The median interval between liver transplantation (LT) and COVID-19 diagnosis was 48 months: 18 recipients had been transplanted less than one year, while 49 recipients had been transplanted more than 5 years (Figure 1). The most common etiology of LT was hepatitis B virus related liver disease (45.7%) (Table 2). LT type was predominantly live donor in 56.9% of the cases. Immunosuppressive Aim protocol comprised of single agent in 42% of the patients, double agents in 48%, triple agents in 7% depending on the duration after LT and center policy. The aim of the present study was to describe the early outcomes of liver transplant recipients with COVID-19. At the time of COVID-19 diagnosis, most recipients (54%) had at least one co-morbidity including diabetes mellitus (31.8%), hypertension (36.4%). Main presenting symptom was malaise (78%)(Figure 2). Laboratory findings in presentation can be seen in table 2. Pneumonic infiltration was observed in 64% of the recipients, Methods 22.5% had relevant increase in liver enzymes. • Liver transplant recipients with concomitant confirmed severe acute respiratory syndrome After the diagnosis, 47% of the recipients were treated in the ward, and 12% was taken to the ICU. Main coronavirus 2 (SARS-CoV-2) infection from 14 tertiary liver transplant centers of Turkey modalities of medical treatment were according to the Turkish Ministry of Health Covid Guidance and center were enrolled into the study. preference (Table 3). Among whole cases 14.7% of them needed nasal oxygen therapy, and 10.2% required • The diagnosis of SARS-CoV-2 infection was made according to the World Health intubation and invasive mechanical ventilation. Organization guidelines and based on the presence of clinical features, laboratory and radiological findings. Overall, 12 recipients (9.4%) died due to COVID-19 related respiratory or multisystem failure (Figure 3). With • The immunosuppressive protocol consisted of calcineurin inhibitors (CNIs) plus multivariate analysis, c-reactive protein (CRP), procalcitonin levels and mechanical ventilation requirement were mycophenolate mofetil (MMF) and a steroid. the risk factors that are significantly associated with mortality (Table 4). • Alternative agents, including sirolimus or everolimus were used.
