Liver function tests in COVID 19: A retrospective record-based study from a tertiary care centre in urban Maharashtra, India.

ABSTRACT

Background: COVID-19 is a multi system disorder and causes various abnormalities in liver function tests. The aim of this study was to estimate the prevalence of abnormal liver function tests in patients of COVID-19 and to describe the association of liver function tests with clinical features and disease severity in these patients. Methods: We retrospectively evaluated and analyzed the liver function tests of all real-time polymerase chain reaction (RT-PCR) positive COVID-19 patients admitted to a tertiary care hospital in Western Maharashtra. The Institutional Ethics Committee of our hospital approved the study. Results: Of the 533 patients included in our study, 50% had abnormal albumin levels while 40.1%, 43.5%, 9.3%, and 6.3% patients had deranged alanine transaminase (ALT) aspartate transaminase (AST), total protein and bilirubin levels, respectively. Hepatocellular injury was observed in 21 (3.9%) patients, and cholestatic liver injury was observed in seven (1.3%) patients. Abnormal liver function test (LFT) was significantly associated with disease severity but not with mortality. Conclusion: Abnormal LFT in patients of COVID-19 is associated with severe disease but not mortality. Liver injury is common in patients of COVID-19.
