RESUMO
BACKGROUND: This subgroup analysis of the European Cubicin Outcomes Registry Experience evaluated the safety and effectiveness of daptomycin in children and adolescent patients (<18 years). METHODS: Clinical outcomes at the end of therapy were assessed as success (cured or improved), failure or nonevaluable. Safety was assessed for up to 30 days post treatment. RESULTS: Eighty-one children and adolescent patients were included in this study. The most common primary infections were bacteremia (19.8%), complicated skin and soft-tissue infection (18.5%), osteomyelitis (13.6%), endocarditis (12.3%), foreign body/prosthetic infection (12.3%), uncomplicated skin and soft-tissue infection (9.9%) and other (13.6%). Daptomycin doses ranged from 4 to >10 mg/kg/day. Median duration of therapy was 12.5 (interquartile range, 7-25; mean, 16.7; standard deviation, 12.8) days. Staphylococcus aureus (46.7%) was the most commonly isolated pathogen (23.8% methicillin-resistant S. aureus). Forty-nine (60.5%) patients completed daptomycin therapy without further antibiotics, 27 (33.3%) switched to another antibiotic, 4 (4.9%) discontinued because of adverse events (AEs) and 1 (1.2%) discontinued because of other reason. Overall, 75 (92.6%; 95% confidence interval: 95.2-100.0%) patients achieved clinical success; 39 of 41 (95.1%) patients receiving daptomycin monotherapy and 36 of 40 (90.0%) patients receiving concomitant antibiotics. Six (7.4%) patients reported AEs, including 1 patient with increased blood creatine phosphokinase. Three (3.7%) patients had serious AEs; 1 (1.2%) had a serious AE possibly related to daptomycin. CONCLUSION: Daptomycin, alone or combined with other antibiotics and/or surgery, demonstrated high clinical success rates against a wide variety of infections and was well tolerated in children and adolescents.
