Stenotrophomonas maltophilia Bacteremia Associated With Severe COVID-19: Successful Treatment With Appropriate Antimicrobial Therapy.

Abstract

Stenotrophomonas maltophilia, an opportunistic pathogen, can cause bacteremia in immunocompromised and debilitated patients. A 50-year-old man with severe coronavirus disease 2019 (COVID-19) was admitted to our hospital's intensive care unit where he underwent extracorporeal membrane oxygenation and ventilatory support. On day 25, he developed S. maltophilia bacteremia originating from an indwelling central venous catheter. After confirming susceptibility, trimethoprim-sulfamethoxazole (80 mg/400 mg) was administered thrice daily. Following improvement, he was weaned from ventilation, recovered sufficiently, and was discharged on day 53. To the best of our knowledge, this is the first report of a patient recovering after antimicrobial treatment for S. maltophilia bacteremia associated with severe COVID-19.
