Two Cases of Lung Abscess and Pleuritis in Severe COVID-19 Patients.

We report two patients who were treated with remdesivir, steroids, and tocilizumab for severe coronavirus disease 2019 (COVID-19) and developed lung abscesses and pleuritis. Although complications due to bacterial infections are often reported in COVID-19 patients, these severe infections are rare. Patients receiving tocilizumab are at a high risk of developing serious bacterial infections, and the diagnosis is often delayed because symptoms such as fever and elevated C-reactive protein levels are often minimal. The possibility of complications owing to severe bacterial infections should be considered when treating patients with severe COVID-19.
