About

Streptococcus pneumoniae is a gram-positive (GP) bacteria responsible for common infections such as community-acquired pneumonia (CAP), as well as complicated infections such as bacteremia, infective endocarditis and meningitis. S. pneumoniae bacteremia ranks among the top 10 most common pathogens associated with bloodstream infections and correlates with high morbidity and mortality worldwide.

Full description

The Infectious Diseases Society of America (IDSA) guidelines for CAP management advocate for short courses of antibiotics for CAP treatment. However, it does not address duration of therapy for common CAP pathogens such as S. pneumoniae when associated with blood stream infections (BSI). 3

Currently, GP bacteremia duration of therapy typically ranges from 7 to 14 days based on IDSA guideline recommendations for Staphylococcus aureus bacteremia with no further definitive consensus.4 Additionally, lack of data and randomized clinical trials on the efficacy and safety of short compared to long treatment duration have led to variability in practice. Most randomized clinical trials as well as retrospective studies on treatment duration, have been conducted mainly in gram-negative BSI
