OBJECTIVES: Cefiderocol is a 'siderophore' cephalosporin active against Gram-negative bacteria, including carbapenem-resistant strains. Data on the use of cefiderocol in real life are limited. We evaluated the efficacy and safety of cefiderocol in the context of our hospital clinical practice.
METHODS: This was a single-centre, observational, retrospective clinical study. We collected data for all patients who received cefiderocol therapy in our hospital, with a focus on clinical outcomes and adverse events.
RESULTS: The study cohort included 28 patients, with a median age of 73 years (25-83 years) and a high burden of co-morbidities. Up to 45 Gram-negative isolates were cultured from the study patients, the most common pathogen being Acinetobacter baumannii (31.1%). Cefiderocol was mostly prescribed for pneumonia (37.8% of cases), bloodstream infection (24.4%), urinary tract infection (22.2%) and intra-abdominal infection (20%), and largely as salvage therapy (92.8%). Of the 18 patients for whom follow-up cultures were available, 14 (77.8%) achieved eradication of the causative micro-organism. Therapeutic success (improvement/resolution of infection) occurred in 64.3% of cases at 7 days and 50% at 14 days from treatment start. Treatment failed in 9 cases (32.1%). No effects on kidney, liver or bone marrow function were observed.
CONCLUSIONS: Cefiderocol showed fair efficacy and excellent tolerability in highly co-morbid patients with a range of multiresistant infections. It may be an option for infections due to colistin-resistant pathogens, when other regimens fail or in cases at risk of kidney dysfunction.
