[Liver injury in patients with moderate II COVID-19 who received dexamethasone monotherapy].

We examined 171 patients with novel coronavirus disease 2019 (COVID-19) with liver injury in the respiratory failure groups and the nonrespiratory failure groups and investigated 41 patients with moderate II COVID-19 with respiratory failure who received dexamethasone (Dex) monotherapy in the liver injury group and the nonliver injury group at the time before treatment. The respiratory failure group had 64% more liver damage than the nonrespiratory failure group, was older, had more men, and had significantly more complications from lifestyle-related diseases such as hypertension and diabetes. Obesity was more common in the liver injury group prior to Dex monotherapy, and the liver CT value was significantly lower than in the nonliver injury group. Liver injury worsened in 41% of patients after Dex monotherapy, but there was no significant difference in the frequency before Dex monotherapy between the liver injury group and the nonliver injury group, and the degree of liver injury was mild in all cases, improving in 38% of the liver injury group. Dex monotherapy was a safe treatment for moderate II COVID-19, which frequently resulted in liver injury.
