No abstract required in this format A 69-year-old woman with coronavirus disease (COVID-19) was transferred to our hospital on day 8 after symptom onset because of increased oxygen demand despite administering dexamethasone (6 mg/day). She had a medical history of Graves' disease and panic disorder. On admission, there were no signs of dyspnea and her oxygen saturation was 95% with 5 L/min via an oxygen mask. Although she was treated with remdesivir in the intensive care unit, her oxygen demand gradually increased. On day 3 of admission, tracheal intubation was performed and piperacillin/tazobactam was started for bacterial pneumonia. She was extubated after completing 10 days of dexamethasone and remdesivir, and 7 days of piperacillin/tazobactam treatment. However, her respiratory condition worsened again, and she was reintubated 3 days later. Her respiratory condition improved after administering methylprednisolone (120 mg/day) and meropenem.
