8. Clinical and Molecular Characterization of Invasive Heteroresistant Vancomycin-Intermediate Staphylococcus aureusInfections in Korean Hospitals

Abstract

ABSTRACTInvasive heteroresistant vancomycin-intermediate Staphylococcus aureus(h-VISA) isolates were identified and characterized in 10 Korean hospitals from July 2009 to June 2011. The prevalence of h-VISA infections was 3.3% (42/1,289). Most (41/42) were health care-associated infections caused by strains belonging to sequence type 5. Cases of persistent bacteremia were frequent (17/42), and 30-day mortality was high (16/40).

9. agrDysfunction Affects Staphylococcal Cassette Chromosome mecType-Dependent Clinical Outcomes in Methicillin-Resistant Staphylococcus aureusBacteremia

Abstract

ABSTRACTStaphylococcal cassette chromosome mecelement (SCCmec) type-dependent clinical outcomes may vary due to geographical variation in the presence of virulence determinants. We compared the microbiological factors and mortality attributed to methicillin-resistant Staphylococcus aureus(MRSA) bacteremia between SCCmectypes II/III and type IV. All episodes of MRSA bacteremia in a tertiary-care hospital (South Korea) over a 4.5-year period were reviewed. We studied the microbiological factors associated with all blood MRSA isolates, including spatype, agrtype, agrdysfunction, and the genes for Panton-Valentine leukocidin (PVL) and phenol-soluble modulin (PSM)-mec, in addition to SCCmectype. Of 195 cases, 137 involved SCCmectypes II/III, and 58 involved type IV. The mortality attributed to MRSA bacteremia was less frequent among the SCCmectype IV (5/58) than that among types II/III (39/137, P= 0.002). This difference remained significant when adjusted for clinical factors (adjusted odds ratio [aOR], 0.14; 95% confidence interval [CI], 0.04 to 0.49; P= 0.002). Of the microbiological factors tested, agrdysfunction was the only significant factor that showed different positivity between the SCCmectypes, and it was independently associated with MRSA bacteremia-attributed mortality (aOR, 4.71; 95% CI, 1.72 to 12.92; P= 0.003). SCCmectype IV is associated with lower MRSA bacteremia-attributed mortality than are types II/III, which might be explained by the high rate of agrdysfunction in SCCmectypes II/III in South Korea.

Abstract

This study was conducted to assess emergence of daptomycin-nonsusceptible (DAP-NS) phenotype in DAP-naive patients with invasive Staphylococcus aureus (ISA) infections in Korea. A total of 208 S. aureus clinical isolates were selected from a previous prospective study on ISA infections and evaluated for DAP-NS. Although DAP has never been introduced in Korea, five DAP-NS S. aureus strains (2.4%) were identified among 208 S. aureus strains collected from ISA infections. The DAP-NS phenotype was observed only in methicillin-resistant S. aureus (MRSA) strains, but not in methicillin-susceptible S. aureus strains. One DAP-NS MRSA strain belonged to sequence type 72 (ST72) and four were ST5 MRSA strains, three of which were heteroresistant vancomycin (VAN)-intermediate S. aureus. All these five DAP-NS MRSA strains were from healthcare-associated infections without prior exposure to VAN within 30 days. While the ST72 MRSA strain exhibited DAP-NS phenotype via charge repulsion mechanism, four ST5 DAP-NS S. aureus strains had charge-independent DAP-NS mechanism. None of the five DAP-NS strains displayed significant increase in cell wall thickness, indicating that altered cell wall thickness was not associated with the observed DAP-NS phenotype.
