Abstract Background & Aims Respiratory failure is the most common cause of death in patients with COVID-19 There has been a lot of investigation to determine predictors of bad outcomes in patients with this illness Liver enzyme elevation has been described in hospitalized patients with severe COVID-19 However, little is known about the significance of liver injury in regards to outcomes Approach & Results We conducted a retrospective chart review of 348 patients admitted with COVID-19 in our quaternary care center Liver injury on admission was defined based on the laboratory cut off i e aspartate aminotransferase (AST) > 35 IU/L and/or alanine aminotransferase (ALT) > 52 IU/L Patients were divided into two cohorts based on presence or absence of liver injury The two cohorts were compared to assess differences in presentation, complications and outcomes The primary outcome was respiratory failure requiring intubation and the secondary outcome was in-hospital mortality The presence of new onset liver enzyme elevation on presentation was associated with increased severity of illness, need for mechanical ventilation and mortality Presence of liver injury increased the chance of acute hypoxic respiratory failure requiring mechanical ventilation by 1 79 times The degree and timeline of liver enzyme elevation during hospitalization corresponded with elevations of other inflammatory markers Conclusion Liver injury appears to correlate with the inflammatory syndrome caused by COVID-19, with the degree of liver injury corresponding with severity We suggest early and continued monitoring of liver enzymes, as they can be useful to identify patients who may need early escalation of care
