COVID-19 in an international European liver transplant recipient cohort.

OBJECTIVE: Knowledge on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in liver transplant recipients is lacking, particularly in terms of severity of the disease. The aim of this study was to describe the demographic, baseline clinical characteristics and early outcomes of a European cohort of liver transplant recipients with SARS-CoV-2 infection. DESIGN: We conducted an international prospective study across Europe on liver transplant recipients with SARS-CoV-2 infection confirmed by microbiological assay during the first outbreak of COVID-19 pandemic. Baseline characteristics, clinical presentation, management of immunosuppressive therapy and outcomes were collected. RESULTS: 57 patients were included (70% male, median (IQR) age at diagnosis 65 (57-70) years). 21 (37%), 32 (56%) and 21 (37%) patients had one cardiovascular disease, arterial hypertension and diabetes mellitus, respectively. The most common symptoms were fever (79%), cough (55%), dyspnoea (46%), fatigue or myalgia (56%) and GI symptoms (33%). Immunosuppression was reduced in 22 recipients (37%) and discontinued in 4 (7%). With this regard, no impact on outcome was observed. Forty-one (72%) subjects were hospitalised and 11 (19%) developed acute respiratory distress syndrome. Overall, we estimated a case fatality rate of 12% (95% CI 5% to 24%), which increased to 17% (95% CI 7% to 32%) among hospitalised patients. Five out of the seven patients who died had a history of cancer. CONCLUSION: In this European multicentre prospective study of liver transplant recipients, COVID-19 was associated with an overall and in-hospital fatality rate of 12% (95% CI 5% to 24%) and 17% (95% CI 7% to 32%), respectively. A history of cancer was more frequent in patients with poorer outcome.

Clinical characteristics and management of a liver transplanted patient admitted with SARS-CoV-2 infection.

We present here the case of a 62-year-old man, who was referred to the emergency department with fever and cough for 3 days. He underwent liver transplantation 4 years earlier due to HCV and NASH-related cirrhosis with hepatocellular carcinoma. At admission he was in reduced general conditions. Nasopharyngeal smear specimen resulted positive for SARS-CoV-2 infection. Pulmonary low-dose CT-scan revealed bilateral subpleural ground-glass infiltrates. O2 saturation was 93%. A treatment with lopinavir/ritonavir and hydroxychloroquine twice daily was started. The patient received also cefepime and remained in isolation. Seven days later imaging showed a progression of the pulmonary infiltrates. Cefepime was replaced by meropenem. During the following 3 days the fever resolved, and the general conditions of the patient significantly improved. Consequently, treatment with lopinavir/ritonavir and hydroxychloroquine was stopped. The evolution of SARS-CoV-2 interstitial pneumonia in this immunosuppressed patient was moderate to severe and liver injury was not clinically significant. Despite its limitations, this case report confirm that the liver may be only mildly affected during SARS-CoV-2 infection, also in liver transplanted patients. Further studies are needed to assess whether the outcome of SARS-CoV-2 infection is worse in immunosuppressed patients than in the general population.
