Objectives: Infections of the spine lead to considerable morbidity and a high cost to the global healthcare system. Currently, evidence for using ceftaroline, an advanced-generation cephalosporin active against methicillin-resistant Staphylococcus aureus (MRSA), in spine infections is limited.
Methods: Describing Infections of the Spine treated with Ceftaroline (DISC) is a multicentre, retrospective, cohort study that evaluated ceftaroline for treating spine infections. Patients were included if they were aged ≥18 years, diagnosed with a spine infection and treated with ceftaroline for ≥28 days. A control group was identified with the same inclusion criteria as the study population except they were treated with a comparator antibiotic for ≥28 days.
Results: Thirty-seven patients were included each in the ceftaroline and control groups. MRSA was the most commonly identified pathogen. With no differences between groups in age, sex, race or co-morbidities (with the exception of chronic kidney disease), treatment with ceftaroline led to similar clinical success compared with the control group. Multivariate regression analysis did not show a significant difference between the two groups in terms of clinical success after controlling for other covariates (adjusted odds ratio=1.49; P=0.711). More patients who received ceftaroline were discharged to an extended-care or rehabilitation facility than home compared with controls (81% vs. 54%, respectively; P=0.024). Side effects and toxicities were rare, including one case of eosinophilic pneumonia in the ceftaroline group.
Conclusions: Ceftaroline appears to be a safe and effective therapy for infections of the spine, including from MRSA.
