Complications associated with Staphylococcus aureus bacteremia
Abstract:
Thirty-nine consecutive Staphylococcus aureus bacteremias were reviewed with particular attention to complications. Thirty-four (87%) of the bacteremias were nosocomial, with intravascular catheters (20 episodes) and dialysis-access sites (six episodes) the most common sources. Complications developed in 36% (14/39) of all bacteremias and in 30% (6/20) of those that were catheter-associated. Acute complications (shock, adult respiratory distress syndrome, disseminated intravascular coagulation) occurred in six patients and were fatal in four. In nine patients metastatic suppurative complications developed, six at sites of preexisting abnormalities. There were no episodes of endocarditis. Most patients received prolonged antibiotic therapy, and the majority of all suppurative complications required surgical intervention. Staphylococcus aureus bacteremia, even when not associated with endocarditis, is a cause of considerable morbidity and mortality in hospitalized patients.
Insights
Staphylococcus aureus bacteremia, often hospital-acquired and linked to catheters, frequently leads to serious complications and death. Even without endocarditis, this infection poses significant risks to hospitalized patients.
Area of Science:
- Infectious Diseases
- Clinical Microbiology
- Hospital Epidemiology
Background:
- Staphylococcus aureus bacteremia (SAB) is a serious bloodstream infection.
- Nosocomial infections are a growing concern in healthcare settings.
- Intravascular devices are common sources of SAB.
Purpose of the Study:
- To review complications associated with Staphylococcus aureus bacteremia.
- To identify common sources and outcomes of SAB.
- To assess the impact of SAB on morbidity and mortality.
Main Methods:
- Retrospective review of 39 consecutive Staphylococcus aureus bacteremia cases.
- Analysis of patient data, focusing on complications and sources.
- Evaluation of treatment and outcomes.
Main Results:
- 87% of SAB cases were nosocomial, with catheters and dialysis sites being primary sources.
- 36% of patients experienced complications, including acute events (shock, ARDS, DIC) and metastatic suppurative complications.
- Four out of six patients with acute complications died; no endocarditis cases were reported.
Conclusions:
- Staphylococcus aureus bacteremia is associated with significant morbidity and mortality in hospitalized patients.
- Catheter-associated bacteremia is common and can lead to severe complications.
- Effective management often requires prolonged antibiotics and surgical intervention.
