Epidemiology of Post-influenza Bacterial Pneumonia Due to a Panton-Valentine Leukocidin Positive Staphylococcus Aureus

Secondary bacterial influenza pneumonia caused by Panton-Valentine Leukocidin Positive Staphylococcus aureus is a rare complication but with poor prognosis. This pathology seems to affect young patients (20-40 years) without any medical history. Since the influenza pandemic of 2009, this complication is more and more mentioned, sought and diagnosed. However, the literature is poor, consisting of case reports, experimental studies on murine models, and low-power studies.

The main objective is to evaluate the mortality in intensive care units of patients post-influenza bacterial pneumonia due to a Panton-Valentine Leukocidin positive Staphylococcus aureus

Inclusion Criteria:

• Patient treated for post-influenza bacterial pneumonia due to a Panton-Valentine Leukocidin positive Staphylococcus aureus in intensive care unit

Exclusion Criteria:

• Minor patient
• Patient under protective measurement
• Absence of bacteriological and / or virological documentation
