Aim
To assess the impact of liver function test (LFT) abnormalities on the prognosis of patients with coronavirus disease 2019 (COVID-19) in a French cohort of hospitalized patients.
Patients and method
From March 13 to April 22, 2020, we collected on a computerized and anonymized database, medical records, laboratory data and clinical outcomes of patients hospitalized for confirmed cases of COVID-19 infection (RT–PCR and/or CT-scan). Patients were followed up until April 22 2020 or until death or discharge. We have considered for statistical analysis, LFT abnormalities with levels greater than two times the upper limit of normal. Composite endpoint included admission to ICU, mechanical ventilation, severe radiologic injury and death to define disease severity.
Results
Among 281 patients with COVID-19, 102 (36.3%) had abnormal LFT. Elevated levels of ALT or AST was associated with the severe composite endpoint in multivariate analysis (OR 6.20, 95% confidence interval 1.84, 20.95, p-value 0.003)
Conclusion
Most of liver injuries are mild and transient during COVID-19. LFT abnormalities are associated with a poorer prognosis and could be a relevant biomarker for early detection of severe infection.
