Abstract
BACKGROUND: The pandemic of coronavirus disease 2019 (COVID-19) has emerged as a relevant threat for humans worldwide. Abnormality in liver function tests (LFTs) has been commonly observed in patients with COVID-19, but there is controversy on its clinical significance. The aim of this study was to assess the prevalence, the characteristics and the clinical impact of abnormal LFTs in hospitalized, non-critically ill patients with COVID-19.
METHODS: In this multicenter, retrospective study, we collected data about 565 inpatients with COVID-19. Data on LFTs were collected at admission and every 7±2 days during the hospitalization. The primary outcome was a composite endpoint of death or transfer to intensive care unit (ICU).
RESULTS: Upon admission 329 patients (58%) had LFTs abnormality. Patients with abnormal LFTs had more severe inflammation and higher degree of organ dysfunction than those without. During hospitalization, patients with abnormal LFTs had a higher rate of transfer to ICU (20vs8%; p<0.001), acute kidney injury (22vs13%, p=0.009), need for mechanical ventilation (14vs6%; p=0.005), and mortality (21vs11%; p=0.004) than those without. In multivariate analysis, patients with abnormal LFTs had a higher risk of the composite endpoint of death or transfer to ICU (OR=3.53; p<0.001). During the hospitalization, 86 patients developed de novo LFTs abnormality, which was associated with the use of tocilizumab, lopinavir/ritonavir and acetaminophen and not clearly associated with the composite endpoint.
CONCLUSIONS: LFTs abnormality is common at admission in patients with COVID-19, is associated with systemic inflammation, organ dysfunction and is an independent predictor of transfer to ICU or death.
