Staphylococcus aureus bacteraemia in a tropical setting: patient outcome and impact of antibiotic resistance
Background: Most information on invasive <em>Staphylococcus aureus</em> infections comes from temperate countries. There are considerable knowledge gaps in epidemiology, treatment, drug resistance and outcome of invasive <em>S. aureus</em> infection in the tropics. Methods: A...

| description | Background: Most information on invasive <em>Staphylococcus aureus</em> infections comes from temperate countries. There are considerable knowledge gaps in epidemiology, treatment, drug resistance and outcome of invasive <em>S. aureus</em> infection in the tropics. Methods: A prospective, observational study of <em>S. aureus</em> bacteraemia was conducted in a 1000-bed regional hospital in northeast Thailand over 1 year. Detailed clinical data were collected and final outcomes determined at 12 weeks, and correlated with antimicrobial susceptibility profiles of infecting isolates. Principal findings: Ninety-eight patients with <em>S. aureus</em> bacteraemia were recruited. The range of clinical manifestations was similar to that reported from temperate countries. The prevalence of endocarditis was 14%. The disease burden was highest at both extremes of age, whilst mortality increased with age. The all-cause mortality rate was 52%, with a mortality attributable to <em>S. aureus</em> of 44%. Methicillin-resistant <em>S. aureus</em> (MRSA) was responsible for 28% of infections, all of which were healthcare-associated. Mortality rates for MRSA and methicillin-susceptible <em>S. aureus</em> (MSSA) were 67% (18/27) and 46 (33/71), respectively (p=0.11). MRSA isolates were multidrug resistant. Only vancomycin or fusidic acid would be suitable as empirical treatment options for suspected MRSA infection. Conclusions: <em>S. aureus</em> is a significant pathogen in northeast Thailand, with comparable clinical manifestations and a similar endocarditis prevalence but higher mortality than industrialised countries. <em>S. aureus</em> bacteraemia is frequently associated with exposure to healthcare settings with MRSA causing a considerable burden of disease. Further studies are required to define setting-specific strategies to reduce mortality from <em>S. aureus</em> bacteraemia, prevent MRSA transmission, and to define the burden of <em>S. aureus</em> disease and emergence of drug resistance throughout the developing world. |
