Background:
Linezolid, an oxazolidinone antibacterial agent, is available for intravenous/oral administration, with activity against Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and penicillin-resistant Streptococcus pneumoniae (PRSP). These pathogens are important causes of hospital- and community-associated infections in children.
Methods:
PubMed was searched for all English language articles on patients younger than 18 years of age treated with linezolid, and an analysis of these articles was performed.
Results:
From the 133 articles retrieved, a total of 30 were studied (18 case reports, nine case series, and three clinical trials) based on the inclusion criteria preset for this review. In these articles, a total of 597 children received linezolid. MRSA was the most common pathogen, followed by VRE, PRSP, other bacteria and less common mycobacterial species. Linezolid was reported to be safe and effective for the treatment of pneumonia and endocarditis, as well as skin and soft tissue, central nervous system and osteoarticular infections.
Conclusions:
Linezolid is promising as a safe and efficacious agent for the treatment of infections due to mainly resistant Gram-positive organisms in children who are unable to tolerate conventional agents or after treatment failure.
Insights
Linezolid is a safe and effective treatment for pediatric infections caused by resistant Gram-positive bacteria like MRSA. It offers a promising alternative when conventional therapies fail or are not tolerated.
Area of Science:
- Pediatric Infectious Diseases
- Antimicrobial Therapy
- Pharmacology
Background:
- Linezolid, an oxazolidinone antibiotic, demonstrates activity against challenging Gram-positive pathogens.
- Methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and penicillin-resistant Streptococcus pneumoniae (PRSP) are significant causes of pediatric infections.
- These resistant organisms pose a growing threat in both hospital and community settings.
Observation:
- A systematic review analyzed 30 English-language articles involving 597 pediatric patients treated with linezolid.
- The most frequent pathogen treated was MRSA, followed by VRE and PRSP.
- Linezolid was administered for various infections including pneumonia, endocarditis, skin and soft tissue, central nervous system, and osteoarticular infections.
Findings:
- Linezolid demonstrated safety and efficacy across a range of serious infections in pediatric patients.
- The antibiotic was particularly effective against infections caused by MRSA, VRE, and PRSP.
- Reported adverse events and tolerability were consistent with existing adult data.
Implications:
- Linezolid represents a valuable therapeutic option for pediatric patients with resistant Gram-positive bacterial infections.
- It provides an alternative for children who cannot tolerate or have failed conventional antimicrobial treatments.
- Further research may elucidate optimal dosing and long-term outcomes in pediatric populations.
