GPT and COVID-19: In both patients, we found the same pattern of changes in laboratory testing of the liver chemistries: 2.5 months after initial diagnosis of COVID-19, aspartate aminotranferase (AST) and alanine aminotransferase (ALT) first increased up to 1000–1200 mg/dl; after this peak, 2 weeks later, the cholestatic parameters increased, with a bilirubin level up to 20 mg/dl and alkaline phosphatase (ALP) up to 1200 mg/dl in patient 1 and patient 2 (Figs. 3 and 4).
