Ceftaroline Plus Daptomycin for Refractory Methicillin- Resistant Staphylococcus aureus Bacteremia in a Child.

Persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia can be difficult to treat, with growing adult literature supporting the combination of ceftaroline and daptomycin for these patients. Here, we report a pediatric patient with persistent MRSA bacteremia with associated cellulitis, fasciitis, myositis, and a deep venous thrombosis causing septic pulmonary emboli. After being unable to clear the bacteremia on vancomycin and then daptomycin monotherapy, the bacteremia cleared quickly with rapid clinical improvement after the addition of ceftaroline to daptomycin. In support of this case, we also review the adult literature supporting treatment with this combination of antibiotics.
