We report two cases recovered from coronavirus disease 2019 with rheumatoid arthritis which had been in remission or low disease activity by taking calcineurin inhibitor (CNI). 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 CNI may have affected the improvement of severe pneumonia.
