[Primary staphylococcal septicemia in adults. A retrospective study]

Area of Science:

• Infectious Diseases
• Bacteriology
• Clinical Medicine

Context:

• Retrospective analysis of 100 primary staphylococcal septicaemia cases across 5 hospitals over 2 years.
• Investigated the epidemiology and clinical outcomes of Staphylococcus aureus bloodstream infections.
• Highlighted the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in a specific hospital setting.

Purpose:

• To review clinical data and identify prognostic factors for staphylococcal septicaemia.
• To assess the mortality rate and patient outcomes associated with Staphylococcus aureus bloodstream infections.
• To understand the characteristics of severe staphylococcal infections, including hospital-acquired and community-acquired cases.

Summary:

• A total of 100 cases of staphylococcal septicaemia were analyzed.
• Staphylococcus aureus was the predominant pathogen, with 6 MRSA isolates identified, all from a single institution.
• The overall mortality rate was 36%, with chronic renal failure and septic shock identified as significant negative prognostic factors.
• Survivors experienced prolonged hospital stays, averaging 42 days, with a notable proportion recovering without long-term complications.

Impact:

• Staphylococcal infections continue to pose a significant public health threat, emphasizing the need for effective treatment strategies.
• The study underscores the importance of considering both hospital-acquired and community-acquired staphylococcal infections.
• Findings contribute to understanding the clinical burden and risk factors associated with Staphylococcus aureus bloodstream infections.
