Clinical results with the use of ceftaroline and ceftobiprole: real-life experience in a tertiary care hospital

Introduction: Ceftaroline and ceftobiprole show activity against resistant Gram-positive cocci as well as good tolerability and are increasingly used in diverse infections. No comparative data on the efficacy and safety of ceftaroline and ceftobiprole in real-life are available. Methods: In this single-centre, observational, retrospective clinical study, the outcomes of patients treated with ceftaroline or ceftobiprole in our hospital were compared, assessing clinical data, use and drug exposure of study antibiotics, and outcomes. Results: A total of 138 patients were included in this study, including 75 treated with ceftaroline and 63 treated with ceftobiprole. Patients treated with ceftobiprole had more comorbidities [median Charlson comorbidity index 5 (4–7) vs. 4 (2–6) for ceftaroline; P = 0.003], a higher prevalence of multiple site infections (P < 0.001) and were more often treated empirically (P = 0.004), whilst ceftaroline was more frequently used in patients with healthcare-related infections. No differences were observed in terms of hospital mortality, length of stay, and rates of clinical cure, improvement or failure. The only independent predictor of outcome was Staphylococcus aureus infection. Both treatments were generally well tolerated. Conclusion: In our real-life experience, ceftaroline and ceftobiprole, applied in different clinical scenarios, were comparable in terms of clinical efficacy and tolerability in a range of severe infections with variable aetiology and different levels of clinical severity. We believe our data may support the clinician in choosing the best option for each therapeutic setting.
