Introduction: liver abnormalities are common in COVID-19 patients and associated with higher morbidity and mortality. We aimed to investigate clinical significance and effect on the mortality of abnormal liver function tests (ALFTs) in COVID-19 patients. Methods: we retrospectively evaluated in a multicentre study all patients admitted with confirmed diagnosis of COVID-19. Results: 434 patients were included in this analysis. Among overall patients, 311 (71.6%) had normal baseline ALT levels. 123 patients showed overall abnormal liver function tests (ALFTs) at baseline [101 ALFTs <2x UNL and 22 ≥2 UNL]. Overall in-hospital mortality was 14% and mean duration of hospitalization was 10.5 days. Hypertension (50.5%), cardiovascular diseases (39.6%), diabetes (23%) were frequent comorbidities and 53.7% of patients had ARDS. At multivariate analysis, the presence of ARDS at baseline (OR=6.11; 95% CI: 3.03-12.32; p<0.000); cardiovascular diseases (OR=4; 95% CI: 2.05-7.81; p<0.000); dementia (OR=3.93; 95%CI:1.87-8.26; p<0.000) and no smoking (OR=4.6; 95% CI: 1.45-14.61; p=0.010) resulted significantly predictive of in-hospital mortality. The presence of ALFTs at baseline was not significantly associated with mortality (OR=3.44; 95% CI=0.81-14.58; p=0.094). Conclusion: ALFTs was frequently observed in COVID-19 patients, but the overall in-hospital mortality was mainly determined by the severity of illness, comorbidities and presence of ARDS.
