BACKGROUNDCOVID-19 severity affects liver damage. The utilization of various anti-COVID-19 drugs in non-severe cases related to liver impairment in the short term seemed intriguing.OBJECTIVESTo assess the dynamic course of liver injury in mild to moderate COVID-19 patients within 10 days of admission and identify risk variables, including medication linkage.METHODSThis prospective cohort study of 300 newly diagnosed mild to moderate COVID-19 cases between September 2021 and October 2022. Tertiary center hospitel, field hospital, or cohort ward admissions were made. Patient demographics and treatment were recorded. The drug, liver injury (LI) dynamics, and clinical course were evaluated.RESULTSHospitel/field hospital (188) and cohort wards (112) had 300 individuals. One hundred fifteen participants had liver damage. Favipiravir (45 %), remdesivir (17.4 %), molnupiravir (11.3 %), Andrographis paniculata (ADG) (8.7 %), and favipiravir plus ivermectin (7.7 %) were given to most LI group (n = 104). The baseline AST/ALT levels of 68 (65.4 %) treated patients were abnormal. Favipiravir, remdesivir, and favipiravir + ivermectin increased mean AST/ALT in participants with normal baseline AST/ALT (p = 0.001, 0.003, and 0.016, respectively), but not molnupiravir or Andrographis paniculata. Transaminase levels climbed in untreated patients independent of baseline. The ground-glass imaging pattern was linked to mild LI. Most subjects had transaminase declines after 10 days. Preexisting liver disease did not increase the likelihood of in-hospital LI.CONCLUSIONIn the real world, a less-than-critical level of liver damage was reported in mild to moderate COVID-19 that allows clinicians to administer a variety of standard medications during short periods of hospital stay.
