Association Between Admission Liver Enzyme Elevation and Mortality in Coronavirus Disease 2019

Öz

Aim: Coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2), predominantly affects the respiratory system but may also involve hepatic dysfunction. This study evaluated liver enzyme abnormalities in hospitalized COVID-19 patients and their association with in-hospital mortality. Material and Methods: This retrospective study enrolled 1455 adults hospitalized with COVID-19. Admission peripheral oxygen saturation (SpO₂), intensive care unit (ICU) and non-invasive mechanical ventilation (NIMV) requirements, and laboratory parameters were recorded. Patients with admission aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) levels ≥ 2 times the upper limit of normal (ULN) formed the patient group, while those with values < 2 times the ULN served as the control group. Mortality predictors were analyzed using logistic regression; cut-off values for age, C-reactive protein (CRP), and SpO₂ were determined by ROC analysis, and survival was evaluated using Kaplan-Meier analysis with log-rank comparisons. Results: The patient group exhibited higher lactate dehydrogenase, total bilirubin, hemoglobin, and CRP levels and lower lymphocyte counts, without differences in in-hospital mortality, ICU admission, or NIMV requirement. Multivariable analysis identified older age, symptom status, lower admission SpO₂, and elevated CRP as independent mortality predictors. ROC analysis yielded cut-offs of 59.5 years, 122.5 mg/L CRP, and 90.5% SpO₂, beyond which survival was shorter (AUC 0.771; p < 0.001). Conclusion: In hospitalized patients with severe COVID-19, admission AST and/or ALT elevations were not associated with mortality or respiratory support, whereas mortality was independently driven by older age, symptom status, elevated CRP, and reduced admission SpO₂, highlighting the prognostic dominance of hypoxia and systemic inflammation over isolated transaminase elevations.
