Insights
Abnormal liver function is common in hospitalized COVID-19 patients in Europe, affecting nearly 67%. These liver test abnormalities predict worse disease and increased mortality risk.
Area of Science:
- Hepatology
- Infectious Diseases
- Internal Medicine
Background:
- COVID-19 has been associated with liver injury in studies from China.
- Limited data exist on liver dysfunction in European COVID-19 patients.
Purpose of the Study:
- To determine the prevalence of abnormal liver function in hospitalized COVID-19 patients in France.
- To assess the predictive value of abnormal liver tests for disease severity and mortality.
Main Methods:
- Retrospective cohort study including 234 RT-PCR confirmed COVID-19 patients.
- Data collected included clinical, biological, and radiological information.
- Multivariate logistic regression analysis was used to identify predictors of outcomes.
Main Results:
- Abnormal liver function was observed in 66.6% of patients upon admission.
- Abnormal liver tests were associated with in-hospital aggravation (OR=4.1) and mortality (OR=3.3).
- Statistical significance was found for both associations (P=.004 and P=.04, respectively).
Conclusions:
- A high prevalence of abnormal liver tests exists in European COVID-19 patients.
- Abnormal liver function on admission is a significant predictor of severe disease course.
- Liver dysfunction is linked to increased in-hospital mortality in this population.
Abstract:
While several studies from China have reported COVID-19-related liver injury, there are currently no data on liver dysfunction in hospitalized COVID-19 patients in Europe. The aim of this study was to describe the prevalence and predictive value of abnormal liver function in patients hospitalized with COVID-19. This was a retrospective cohort study of confirmed COVID-19 patients hospitalized in two referral hospitals in France. Clinical, biological and radiological data were collected and analysed. In all, 234 patients confirmed to have COVID-19 by RT-PCR were included. Liver function was abnormal in 66.6% of patients on admission. In multivariate logistic regression, abnormal liver test on admission were associated with in-hospital aggravation (OR = 4.1, 95% CI 1.5-10.8; P = .004) and mortality (OR 3.3; 95% CI = 1.04-10.5; P = .04). This study of liver tests in a European COVID-19 population confirms a high prevalence of abnormal liver tests on admission that are predictive of severe disease course and higher in-hospital mortality.
