Abstract:
Streptococcus pneumoniae is the leading bacterial cause of community-acquired respiratory tract infections. Prior to the 1970s this pathogen was uniformly susceptible to penicillin and most other antimicrobials. However, since the 1990s there has been a significant increase in drug-resistant Streptococcus pneumoniae (DRSP) due, in large part, to increased use of antimicrobials. The clinical significance of this resistance is not definitely established, but appears to be most relevant to specific MICs for specific antimicrobials. Certain beta-lactams (amoxicillin, cefotaxime, ceftriaxone), the respiratory fluoroquinolones, and telithromycin are among several agents that remain effective against DRSP. Continued surveillance studies, appropriate antimicrobial usage campaigns, stratification of patients based on known risk factors for resistance, and vaccination programmes are needed to appropriately manage DRSP and limit its spread.
Insights
Drug-resistant Streptococcus pneumoniae (DRSP) infections are increasing due to antimicrobial use. While some drugs remain effective, continued surveillance, responsible antimicrobial use, and vaccination are crucial for managing DRSP.
Area of Science:
- Microbiology
- Infectious Diseases
- Pharmacology
Background:
- Streptococcus pneumoniae is a primary cause of community-acquired respiratory infections.
- Historically susceptible to penicillin, increased antimicrobial use since the 1990s has led to significant drug-resistant Streptococcus pneumoniae (DRSP).
Purpose of the Study:
- To review the emergence and management of drug-resistant Streptococcus pneumoniae (DRSP).
- To highlight effective antimicrobial agents and strategies for controlling DRSP.
- To emphasize the need for ongoing surveillance and appropriate antimicrobial stewardship.
Main Methods:
- Literature review of antimicrobial resistance trends in Streptococcus pneumoniae.
- Analysis of clinical significance and effective treatment options for DRSP.
- Evaluation of public health strategies for DRSP management.
Main Results:
- Increased prevalence of DRSP linked to antimicrobial usage.
- Clinical significance of resistance varies with specific antimicrobial-minimum inhibitory concentrations (MICs).
- Agents like amoxicillin, cefotaxime, ceftriaxone, respiratory fluoroquinolones, and telithromycin show continued efficacy against DRSP.
Conclusions:
- Effective management of DRSP requires a multi-faceted approach.
- Continued surveillance, antimicrobial stewardship, risk stratification, and vaccination are essential.
- Limiting the spread of DRSP necessitates coordinated public health interventions.
