Eosinophilic pneumonia caused by cefepime: A case report and review

Abstract

Eosinophilic pneumonia (EP) is characterized by accumulation of eosinophils in the lungs and has been associated with several medications, including antimicrobials. Cefepime is a commonly used broad-spectrum antimicrobial agent for the treatment of nosocomial infections but to date has not been associated with EP. We report the first documented case of EP secondary to cefepime for the treatment of pneumonia. The patient’s peripheral eosinophilia and leukocytosis resolved promptly after discontinuation of cefepime and initiation of steroid treatment.
