Summary
Salmonella bacteremia occurred in 0.99% of hospitalized patients, with Salmonella enteritidis being the most common serotype. Risk factors included sideropenic anemia, cerebral palsy, and cardiac disease, with third-generation cephalosporins proving effective treatment.
Area of Science:
- Infectious Diseases
- Microbiology
- Epidemiology
Context:
- Non-typhi Salmonellae are invasive bacteria causing bacteremia and localized infections.
- Incidence of Salmonella bacteremia varies, with higher rates in young children and the elderly.
- Specific serotypes like Salmonella typhimurium, Salmonella choleraesuis, and Salmonella Virchow are particularly invasive.
Purpose:
- To determine the incidence of Salmonella bacteremia in hospitalized patients.
- To identify risk factors associated with Salmonella bacteremia.
- To evaluate treatment outcomes for Salmonella bacteremia.
Summary:
- A study of 1309 patients hospitalized with Salmonella gastroenteritis found a 0.99% incidence of Salmonella bacteremia.
- Salmonella enteritidis was the predominant serotype (83.33%).
- Risk factors included sideropenic anemia (25%), cerebral palsy (8.33%), and chronic cardiac disease (8.33%).
Impact:
- The study highlights a low incidence of Salmonella bacteremia in the studied population, potentially due to the age distribution of patients.
- Positive blood cultures are crucial for diagnosing bacteremia, even with negative stool cultures.
- Third-generation cephalosporins are effective in treating Salmonella bacteremia, leading to complete recovery without sequelae.
