Staphylococcus aureus bacteremia in hemodialysis patients
Journal of Dialysis
|January 1, 1977
Summary
Staphylococcus aureus bacteremia is a serious risk for hemodialysis patients, often linked to vascular access. Prolonged antibiotic treatment is recommended to combat these infections and prevent complications.
Area of Science:
- Infectious Diseases
- Nephrology
- Microbiology
Background:
- Bacteremia poses a significant threat to patients undergoing hemodialysis.
- Vascular access, particularly arteriovenous fistulas, is a common source of bloodstream infections.
Purpose of the Study:
- To investigate the incidence, sources, and outcomes of Staphylococcus aureus bacteremia in hemodialysis patients.
- To determine the role of vascular access in S. aureus bacteremia among this population.
Main Methods:
- Retrospective analysis of 21 episodes of S. aureus bacteremia in 15 male hemodialysis patients.
- Phage typing was used to differentiate between reinfection and relapse.
Main Results:
- Vascular access infections accounted for 65% of initial bacteremias.
- Arteriovenous fistulas were the most common access type implicated.
- Recurrent episodes were predominantly due to reinfection.
- Complications included endocarditis, osteomyelitis, and septic embolism; one patient died.
Conclusions:
- Hemodialysis patients with S. aureus bacteremia require aggressive management.
- A minimum of 6 weeks of beta-lactamase-resistant antibiotic therapy is recommended.
