Abstract:
Linezolid, an oxazolidinone antimicrobial agent that acts by inhibiting protein synthesis in a unique fashion, is used in the treatment of community-acquired pneumonia, skin and soft-tissue infections and other infections caused by Gram-positive bacteria including VRE and methicillin-resistant staphylococci. Currently, linezolid resistance among these pathogens remains low, commonly <1.0%, although the prevalence of antibiotic resistance is increasing in many countries. Therefore, the development of resistance by clinical isolates should prompt increased attention of clinical laboratories to routinely perform linezolid susceptibility testing for this important agent and should be taken into account when considering its therapeutic use. Considering the importance of linezolid in the treatment of infections caused by Gram-positive bacteria, this review was undertaken to optimize the clinical use of this antibiotic.
Insights
Linezolid is a crucial antibiotic for Gram-positive bacterial infections. Monitoring for linezolid resistance is essential to ensure its continued effectiveness in treating serious infections.
Area of Science:
- Microbiology
- Infectious Diseases
- Pharmacology
Background:
- Linezolid is an oxazolidinone antimicrobial effective against Gram-positive bacteria, including VRE and MRSA.
- It functions by uniquely inhibiting bacterial protein synthesis.
- Increasing antibiotic resistance globally necessitates careful management of effective agents like linezolid.
Purpose of the Study:
- To review and optimize the clinical application of linezolid.
- To highlight the importance of susceptibility testing for linezolid.
Main Methods:
- Literature review on linezolid's efficacy and resistance patterns.
- Analysis of current clinical guidelines and resistance trends.
Main Results:
- Linezolid remains effective with low resistance rates (<1.0%) in many Gram-positive pathogens.
- Emerging resistance warrants increased vigilance and routine susceptibility testing.
Conclusions:
- Linezolid is vital for treating infections caused by resistant Gram-positive bacteria.
- Routine susceptibility testing and careful therapeutic consideration are recommended to preserve linezolid's efficacy.
