Abstract
WHAT IS KNOWN AN OBJECTIVE: Our objective is to report a paediatric case of high-level ceftaroline resistance without previous ceftaroline exposure.
CASE DESCRIPTION: A 20-month-old, 12 kg, female with invasive MRSA infection presented with high-level ceftaroline resistance with no previous ceftaroline exposure.
WHAT IS NEW AND CONCLUSION: To our knowledge, our case is the first report of high-level ceftaroline resistance evident in a paediatric patient with invasive infection due to MRSA, without history of prior ceftaroline exposure. This case illustrates the importance of weighing the risk of resistance with the benefits of use when starting therapy empirically prior to susceptibility results, even in patients without previous drug exposure.
