Summary: | Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has become a pathogen of major importance in pediatric patients. CA-MRSA can cause skin and soft tissue infection in children and young active adults with no predisposing factors, and life-threatening infections such as meningitis or necrotizing pneumonia have been reported. We report here a case of CA-MRSA meningitis complicated by acute left middle cerebral artery (MCA) infarction and necrotizing pneumonia in a previously healthy 1-month-old Vietnamese boy. He was firstly treated with vancomycin, but changed to linezolid because of persistent fever and low vancomycin trough level.
He recovered successfully with residual right-sided hemiparesis. The mode of transmission of CA-MRSA and the mechanism of cerebral infarction (thrombotic or embolic) were unknown. The isolate was genotyped as staphylococcal cassette chromosome (SCC) mec type V with a novel sequence type (ST) 5959 harboring the Panton–Valentine leukocidin (PVL) gene. ST 5959 is a double locus variant of ST 59, which is a major PVL-positive CA-MRSA strain isolated in invasive disease in Asian countries. This case report may serve as a warning about the dissemination of PVL-positive CA-MRSA in and around Japan, with the possibility of causing serious life-threatening disease. The potential of linezolid for the treatment of MRSA meningitis as one of the alternative MRSA therapeutic drugs is also discussed. |
