Evaluation of Ceftaroline Use in Pediatric Patients: A Retrospective Case Series

Background/Objectives: Ceftaroline (CPT) is a broad-spectrum, fifth-generation cephalosporin with in vitro activity against methicillin-resistant Staphylococcus aureus (MRSA) and drug-resistant Streptococcus pneumoniae. Real-world data on its use in pediatric patients remain limited. This study aimed to the describe clinical characteristics and outcomes associated with CPT use in pediatric patients at a pediatric academic medical center. Methods: This retrospective case series evaluated patients under 18 years of age who received CPT between November 2016 and August 2023. The primary outcome was clinical success, defined as a composite of 30-day survival, absence of microbiological recurrence within 30 days, and/or resolution of acute infection signs and symptoms without therapy modification due to clinical failure. The secondary outcomes included adverse effects potentially attributable to CPT and the clinical rationale guiding its use. Results: Among 25 patients, most were male (68%) with a median (IQR) age of 3.4 (1.4-14.3) years. The indications for use commonly included respiratory infections (48%), bacteremia (16%), and/or skin and soft tissue (12%) infections. The frequently used dosing regimens included 12 mg/kg (36%) and 8 mg/kg (28%) q8hr, with a median (IQR) duration of therapy of 4.6 (1.7-10.0) days. Clinical success was achieved in 96% of patients. No adverse effects attributable to CPT were observed and CPT was commonly used for escalation (40%) and/or issues with alternative therapies (36%). Conclusions: CPT use was associated with high clinical success rates and no observed adverse effects in this pediatric report. These findings support its use as a therapeutic option when the alternatives are limited. Larger multicenter studies are needed to further evaluate the clinical outcomes and safety of CPT use in pediatric patients.
