Potential role of the microbiome in liver injury during COVID-19: Further research is needed

Abstract

Although different studies have associated coronavirus disease 2019 (COVID-19) with the occurrence of liver injury, the hepatic injury route during the COVID-19 course is not yet fully understood. In order to better understand the mechanisms of the disease, the human gut microbiota has been the subject of extensive discussion in the context of COVID-19 pathophysiology. However, many questions remain, including the risks of liver injury due to COVID-19 specific populations. Further research in this field could allow the discovery of new personalized treatment strategies aimed at improving the microbiota composition, thereby reducing COVID-19 severity and its complications in different populations. In this article, we discussed basic mechanisms of severe acute respiratory syndrome coronavirus 2 infection and recent evidence on the relationship between COVID-19, the gut microbiome and liver injury as well as proposed recommendations for further research.
