In group A, 8 deaths were reported, two of which were associated with severe liver failure since admission (case 1 of a 65-year-old male patient with a severe form of COVID-19 who had AST 10 618 U/L and ALT 4260 U/L and case 2 of an 85-year-old woman with a severe form of COVID-19 who had an AST of 5700 U/L and an ALT of 2115 U/L). This evidence concerns the gene GPT and liver failure.
