Current Views About the Link between SARS-CoV-2 and the Liver: Friends or Foe?

Abstract

Abstract: The emergence of the novel coronavirus and the pandemic resulting from its spread have led to significant negative impacts on health, economy, relationships, and others. Particularly in the field of hospital care, the need for a greater number of patients has led to a breakdown of the system. Gastrointestinal manifestations are common in SARS-COV 2 patients, while 10% of those who are sick exhibit symptoms only from gastrointestinal without any manifestation on the part of the respiratory tract. The main manifestations are nausea, vomiting, diarrhoea, and anorexia. It is also interesting to note that biochemical liver disorder is a frequent finding and is associated with a worse prognosis and higher probability admission to intensive care. It was also observed that RNA from the virus was found in the stool several days after the tests came back negative pulmonary secretions, while rectal swab virus detection methods were used with a lower but comparable sensitivity to that of nasal swabs. Gastrointestinal symptoms in SARS-COV 2 infection are common and their search should be part of the initial diagnosis approach and have a connection with the gut microbiota dysbiosis and this can lead to an alteration of the gut/liver axis.
