From advanced disease to transplantation: an overview of the liver at the time of COVID-19 pandemic

In 2020, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) also known as coronavirus disease 2019 (COVID-19) disrupted global health, causing hundreds of thousands of deaths worldwide. The liver injury appears to be one of the possible systemic manifestations of COVID-19 disease although the mechanisms causing such injury are not entirely clear. At the beginning of the pandemic, patients with chronic diseases, such as liver cirrhosis, or special populations, such as liver transplant recipients, were considered at higher risk of complications and poor clinical outcomes. Thus, the national transplant programmes have been severely hampered by the COVID-19 pandemic. Furthermore, liver transplant patients are potentially more vulnerable to SARS-CoV-2 infection due to immune suppression, ageing, and metabolic or cardiovascular comorbidities. This review analyses the increasing amounts of data collected in recent months concerning liver cirrhosis and liver transplants to understand if this finding is still relevant with respect to COVID-19 manifestations.

A real-world experience of SARS-CoV-2 infection in a tertiary referral centre of Montréal: Unexpected low prevalence and low mortality

BACKGROUND

The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with chronic liver disease (CLD) and liver transplant (LT) recipients remains a concern. The aim of this study was to report the impact of coronavirus disease 2019 (COVID-19) infection among patients at the tertiary health care centre Centre hospitalier de l'Université de Montréal (CHUM) during the first wave of the SARS-CoV-2 pandemic.

METHODS

This real-world, retrospective cohort included all patients admitted to our liver unit and/or seen as an outpatient with CLD with or without cirrhosis and/or LT recipients who tested positive to SARS-CoV-2 infection. Cases were considered positive as defined by the detection of SARS-CoV-2 by reverse-transcription polymerase chain reaction (RT-PCR) on nasopharyngeal swabs.

RESULTS

Between April 1 and July 31, 2020, 5,637 were admitted to our liver unit and/or seen as outpatient. Among them, 42 were positive for SARS-CoV-2. Twenty-two patients had CLD without cirrhosis while 16 patients had cirrhosis at the time of the infection (13, 2, and 1 with Child-Pugh A, B, and C scores, respectively). Four were LT recipients. Overall, 15 of 42 patients (35.7%) were hospitalized; among them, 7 of 42 (16.7%) required respiratory support and 4 of 42 (9.5%) were transferred to the intensive care unit. Only 4 of 42 (9.5%) patients died: 2 with CLD without cirrhosis and 2 with CLD with cirrhosis. Overall survival was 90.5%.

CONCLUSION

This real-world study demonstrates an unexpectedly low prevalence and low mortality in the context of SARS-CoV-2 infection among patients with CLD with or without cirrhosis and LT recipients.
