Panton-Valentine leukocidin-producing Staphylococcus aureus (PVL-SA) is associated with relapsing multifocal skin and soft tissue infections (SSTI), necrotizing pneumonia (NP) and severe musculoskeletal infections. Rarely, PVL-producing S. aureus can cause septic arthritis, bacteraemia (blood poisoning) or necrotising pneumonia. Kaushik A, Kest H. Pediatric methicillin-resistant Staphylococcus aureus Osteoarticular infections. Multilocus sequence typing analysis of a subset of the strain collection showed that the 15 PVL-positive strains were within clonal complex (CC) 30 (n = 7), CC 121 (n = 3), CC 1 (n = 2), CC 8 (n = 1), CC 22 (n = 1), and CC 45 (n = 1) (Table) (8).

The 2 MRSA clones in the United States most closely associated with community outbreaks, USA400 (MW2 strain, ST1 lineage) and USA300, often contain Panton-Valentine leukocidin (PVL) genes and, more frequently, have been associated with skin and softtissue infections. However, the precise role of single virulence determinants in relation to infection is hard to establish.

In our patient, the genotype of the PVL-MRSA was ST121, that is, to our knowledge, the first reported in a paediatric patient in Italy. J Pathog. PVL may be produced by different strains of SA, in particular both Methicillin-Sensitive SA (MSSA) and MRSA [7]. Methicillin-resistance prevalence was 24%. Panton-Valentine leukocidin (PVL)-producing Staphylococcus aureus is emerging as a serious problem worldwide. The cna gene was the most predominant in the MSSA strains in HCTM, with 51.59%, followed by seh (21.82%), PVL (10.23%) and TSST-1 (6.82%). Most PVL-SA identified in the UK are. (2006). PVL-SA infection mainly occurs in young, healthy individuals, but it can affect other patient groups including children. Expansion and increased incidence of such infections, however, are more recent, and further epidemiologic studies for tracking this phenomenon are still warranted. Privacy PVL is associated with skin and soft tissue infections but not with bacteremia, which suggests that PVL is not likely to be involved in the pathogenesis of bacteremia. We chose ceftaroline as anti-MRSA agent as it is effective and safe similarly to vancomycin [28, 29]. The bicomponent toxin PVL is associated with severe necrotizing pneumonia in children. Our report highlights the importance of improving awareness of this severe infection, as a prompt diagnosis and adequate manage is essential in order to save life and to prevent serious complications.

This finding is in agreement with previously reported low PVL prevalences by Prevost et al. ICH GCP. PVL-SA predominantly results in skin and soft tissue infections (SSTIs) but may also cause invasive disease, including necrotising pneumonia, which may affect healthy young individuals and has a high mortality. In 2003, during the SARS-CoV outbreak, an increase in S. aureus superinfection (mostly methicillin-resistant S. aureus ventilator-acquired pneumonia) was described.

Because of deterioration of respiratory, renal, and liver functions, venovenous extracorporeal membrane oxygenation and anticoagulation were initiated 10 days after ICU admission. Methicillin-resistant S. aureus (MRSA) accounted for 19% of S. aureus isolates, associated with mostly staphylococcal cassette chromosome mec (SCCmec) type IV, or V. Panton-Valentine leukocidin (PVL) genes were detected in methicillin-susceptible S. aureus (MSSA) at significantly higher rate (39%) than in MRSA (22%). The PVL toxin is a combination of two proteins (Leuk S and F) that act synergistically to activate and destroy leukocytes by creating lytic pores (Finck-Barbancon et al., 1993), and are associated with necrotic infections of skin, subcutaneous fat and pneumonia (community-acquired). Clinical practice guidelines by the infectious diseases society of america for the treatment of methicillin-resistant Staphylococcus aureus infections in adults and children: executive summary.

This antibiotic regimen was well tolerated by the patient and without adverse reaction. Since 2010, we have identified 15 reported cases of paediatric PVL-SA severe infections and Table1 summarizes the main results of these reports regarding the clinical presentations, radiological findings, treatment and outcome [2,3,4,5, 15,16,17,18,19,20,21,22,23]. PVL-SA strains can be identified by detection of genes encoding PVL or the toxin itself [9]. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. In a retrospective study of Hardy et al., among the six patients with PVL-SA bone and joint infections, there were 2 cases of necrotizing pneumonia, 2 cases of pericarditis and 1 death caused by cardiac tamponade.
