Both methicillin-sensitive S. aureus MSSA and methicillin-resistant S. aureus MRSA may carry the PVL-phage but the majority of publications relate to community-associated methicillin-resistant S. aureus CA-MRSA or mixed patient groups. This study focuses on necrotizing pneumonia due to methicillin-sensitive S. aureus strains with the purpose to determine factors associated with outcome. Methods We report a patient with PVL secreting MSSA necrotizing pneumonia and performed a systematic review of similar case in the literature. We analyzed factors associated with outcome. Results A total of 32 patient descriptions were retained for analysis. Septic shock p influenza-like prodrome p and the absence of a previous skin and soft-tissue infection p were associated with fatal outcome. In multivariate analysis influenza-like prodrome odds ratio OR 95 confidence interval CI p and absence of previous skin and soft-tissue infection OR 95 CI p remained significant predictors of death. Conclusions Influenza-like prodrome may be predictive of adverse outcome in PVL-secreting MSSA necrotizing pneumonia. In contrast previous skin and soft-tissue infection may be associated with improved prognosis. Background Staphylococcus aureus is estimated to cause 1-10 of community acquired pneumonias CAP and 20-50 of nosocomial .
