Introduction
Community-acquired necrotizing pneumonia caused by Panton-Valentine leukocidin (PVL)-secreting Staphylococcus aureus is a highly lethal infection, which mainly affects healthy children and young adults [1, 2]. This study focuses on necrotizing pneumonia due to methicillin-sensitive S. aureus strains, with the purpose to determine factors associated with outcome.
Methods
We performed a systematic review of case reports on PVL-secreting MSSA necrotizing pneumonia and analyzed factors associated with outcome.
Results
A total of 32 patient descriptions were retained for analysis. Septic shock, influenza-like prodrome and the absence of a previous skin and soft tissue infection were associated with fatal outcome. In multivariate analysis, influenza-like prodrome (OR 7.44; 95% CI: 1.24 to 44.76; P = 0.028) and absence of previous skin and soft tissue infection (OR 0.09; 95% CI: 0.010 to 0.86; P = 0.036) remained significant predictors of death. See Table 1.
Conclusion
Influenza-like prodrome may be predictive of adverse outcome and previous skin and soft tissue infection may be associated with improved prognosis.
