Ceftaroline-related acute eosinophilic pneumonia

We report a case of fever and acute hypoxic respiratory failure with bilateral interstitial pulmonary infiltrates while on ceftaroline therapy for sternal osteomyelitis and ascending aortic graft infection secondary to MRSA. Laboratory studies revealed peripheral blood eosinophilia (>3000 cells/mm3). After exclusion of infectious, autoimmune, and other extrinsic allergic causes of pneumonia, ceftaroline-related acute eosinophilic pneumonia was suspected. Ceftaroline was discontinued and a therapeutic trial of high-dose steroid was initiated. Significant improvement of clinical symptoms and hypoxia was achieved after 24 h of steroid therapy. There was no recurrence of clinical symptoms after completing steroid course, which supported our suspicion of acute eosinophilic pneumonia from ceftaroline. Radiographic improvement of pulmonary infiltrates occurred 4 weeks later with complete resolution at 3 months from the initial event. The current case adds to this rarely reported adverse effect from this relatively newer antimicrobial agent. Increased awareness, early recognition, discontinuation of medication, and steroid therapy are key in favorable clinical outcome and recovery.
