COVID-19 Survivors with Calcineurin Inhibitors-Treated Rheumatoid Arthritis.

We report two cases recovered from COVID-19 with rheumatoid arthritis which had been in remission or low disease activity by taking calcineurin inhibitor. Both cases had moderate to severe pneumonia treated with intravenous dexamethasone or in the severe case remdesivir in addition to it. These cases suggest that the use of calcineurin inhibitor may have affected the improvement of severe pneumonia.
