Biochemical indices like alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), creatinine (MMD= 6.89 u/l, 11.96 u/l, 1.04 mmol/l, 4.87 μmol/l) were significantly elevated in severe or critical cases in comparison to non-severe COVID-19 patients (Moutchia et al., 2020). This evidence concerns the gene GPT and COVID-19.
