Background
Previous studies suggested that liver function tests (LFTs) could serve as a prognostic tool in assessing the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. However there have been no published large-scale studies conducted for Koreans with similar topics.
Methods
This research was conducted using the data from two hospitals in Korea. Data from 4,367 adults out of 4,423 patients without missing values, end-stage renal disease, a history of kidney transplant, or use of immunosuppressants were analyzed. We used LFTs measured on the day of hospitalization for SARS-CoV-2 infection. The main outcomes of interest were two things: all-cause mortality and the incidence of acute kidney injury (AKI). Statistical analysis was performed with logistic regression.
Results
Analysis of data for 4,367 people (mean age 54.5±18.3 years, 54.3% female) suggests that high bilirubin is associated with high mortality (adjusted hazard ratio [aHR], 1.794; 95% confidence interval [CI], 1.292 to 2.492; P<0.001) and risk of AKI (aHR, 1.263; 95% CI, 1.005 to 1.588; P=0.045). Also low albumin level is associated with high mortality (aHR, 0.574; 95% CI, 0.378 to 0.873; P<0.001). However no significant impact of alanine transferase and alkaline phosphatase on mortality and the incidence of AKI is identified.
Conclusion
Abnormal LFTs, especially in aspartate transaminase, total bilirubin and albumin level, is relevant to higher mortality and risk of AKI in Koreans with COVID-19. Therefore LFTs should be performed early in hospitalization as a screening tool for risk stratification in Korean COVID-19 patients.
