Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [COVID-19] quickly turned into a pandemic. Gastrointestinal involvement, especially liver diseases, is one of the main complications of COVID-19 patients.
The current study aimed to evaluate the high incidence of liver involvement in COVID-19 hospitalized patients and its association with mortality.
A total of 560 hospitalized patients with a confirmed diagnosis of COVID-19 were included. Death was considered as the outcome. In addition to liver enzymes, demographic, clinical, and other laboratory data were also collected. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels ≥ 40 were considered as abnormal. To investigate the association between abnormal levels of liver enzymes and death, multiple regression logistic was used.
According to the findings, 29.1% (95% CI = 25.3% - 32.9%) of patients had high levels (≥ 40 IU) of ALT, and 45.1% (95% CI = 40.9% - 49.3%) had high levels of AST (≥ 40 IU). The frequency (based on %) of high levels of AST (≥ 40 U/liter) was significantly higher in patients who died [67.3% (95% CI = 54.5% - 80.1%] of COVID-19 than those who survived [44.9% (95% CI = 39.7% - 50.0%)] (P-value < 0.001). No significant difference was detected in ALT between expired [29.1% (95% CI = 16.7% - 41.5%)] and survived patients [30.7% (95% CI = 25.9% - 35.5%] (P-value = 0.791). AST was found to have an independent association with death in multiple logistic regression (Wald = 4.429, OR (95% CI) = 1.014 (1.008 - 1.020), P-value = 0.035).
Liver involvement is a common finding in COVID-19 hospitalized patients. Higher levels of AST were significantly associated with an increased mortality rate in COVID-19 patients.
