Insights
Patients with COVID-19 and liver injury (LI) face significantly higher risks of mortality and poor outcomes. This large study highlights the severe consequences of liver injury in coronavirus disease 2019 patients.
Area of Science:
- Hepatology
- Infectious Diseases
- Critical Care Medicine
Background:
- Liver injury (LI) is common in COVID-19 patients.
- Large-scale studies on risk factors and outcomes of LI in COVID-19 are limited.
Purpose of the Study:
- To evaluate risk factors and clinical outcomes of LI in a large inpatient COVID-19 cohort.
- To compare outcomes of patients with mild liver enzyme elevation (MEL) and LI against a control group.
Main Methods:
- Included adult COVID-19 patients hospitalized between March and April 2020.
- Defined LI and MEL based on peak liver enzyme levels (ALT/AST, ALP/bilirubin).
- Compared patients with MEL and LI to a control group with normal liver enzymes.
Main Results:
- 53.2% had MEL, 20.5% had LI among 1935 patients.
- LI group had higher proportion of men, older patients, and African-Americans.
- LI significantly increased risk of mortality (RR 4.26), ICU admission (RR 5.52), intubation (RR 11.01), and 30-day readmission (RR 1.81).
Conclusions:
- COVID-19 patients with liver injury face significantly increased mortality risk.
- Liver injury is associated with poorer clinical outcomes in coronavirus disease 2019.
- Findings underscore the importance of monitoring liver function in COVID-19 patients.
Background:
There is a high prevalence of liver injury (LI) in patients with coronavirus disease 2019 (COVID-19); however, few large-scale studies assessing risk factors and clinical outcomes in these patients have been done.
Aims:
To evaluate the risk factors and clinical outcomes associated with LI in a large inpatient cohort of COVID-19 patients.
Methods:
Adult patients with COVID-19 between March 1 and April 30, 2020, were included. LI was defined as peak levels of alanine aminotransferase/aspartate aminotransferase that were 3 times the ULN or peak levels in alkaline phosphatase/total bilirubin that were 2 times the ULN. Mild elevation in liver enzymes (MEL) was defined as abnormal peak liver enzyme levels lower than the threshold for LI. Patients with MEL and LI were compared to a control group comprising patients with normal liver enzymes throughout hospitalization.
Results:
Of 1935 hospitalized COVID-19 patients, 1031 (53.2%) had MEL and 396 (20.5%) had LI. Compared to control patients, MEL and LI groups contained proportionately more men. Patients in the MEL cohort were older compared to control, and African-Americans were more highly represented in the LI group. Patients with LI had an increased risk of mortality (relative risk [RR] 4.26), intensive care unit admission (RR, 5.52), intubation (RR, 11.01), 30-day readmission (RR, 1.81), length of hospitalization, and intensive care unit stay (10.49 and 10.06 days, respectively) compared to control.
Conclusion:
Our study showed that patients with COVID-19 who presented with LI had a significantly increased risk of mortality and poor clinical outcomes.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
