Abstract:
Resistance to antimicrobial agents, which was recognized more than 50 years, continues to be a major cause of increased morbidity, mortality and health care cost. Overuse of antibiotics is considered the major contributing factor; however, poor implementation of infection control measures, prolonged hospitalization, admission to intensive care units and the use of invasive procedures are other contributing factors. The authors review the epidemiology, mechanism of resistance, treatment options and prevention measures of infections caused multi-drug resistant S. pneumoniae, methicillin-resistant S. aureus (MRSA), macrolide-resistant S. pyogenes and vancomycin-resistant enterococci (VRE) in pediatric patients. Antibacterial resistance among Gram-negative organisms, including extended spectrum beta-lactamase (ESBL) producing enteric bacteria, and the management and prevention of infections caused by these organisms are also discussed.
Insights
Antimicrobial resistance is a growing threat, increasing illness, death, and healthcare costs. This review covers drug-resistant bacteria like MRSA and VRE in children, focusing on prevention and treatment strategies.
Area of Science:
- Pediatric Infectious Diseases
- Antimicrobial Resistance
- Public Health
Background:
- Antimicrobial resistance (AMR) poses a significant global health challenge, leading to increased morbidity, mortality, and healthcare expenditures.
- Key contributing factors to AMR include antibiotic overuse, inadequate infection control, prolonged hospitalization, intensive care unit admissions, and invasive procedures.
Purpose of the Study:
- To review the epidemiology, mechanisms of resistance, treatment, and prevention of infections caused by multidrug-resistant organisms in pediatric patients.
- To discuss antibacterial resistance in Gram-negative organisms, including extended-spectrum beta-lactamase (ESBL) producing bacteria, and their management.
Main Methods:
- Literature review focusing on pediatric infections caused by specific multidrug-resistant pathogens.
- Synthesis of information on epidemiology, resistance mechanisms, clinical manifestations, treatment options, and prevention strategies.
Main Results:
- Detailed review of common pediatric resistant pathogens: Streptococcus pneumoniae, Staphylococcus aureus (MRSA), Streptococcus pyogenes, and Enterococci (VRE).
- Discussion of resistance trends and challenges posed by Gram-negative bacteria, such as ESBL-producing Enterobacteriaceae.
Conclusions:
- Effective infection control measures and judicious antibiotic use are crucial for combating pediatric antimicrobial resistance.
- Comprehensive strategies encompassing surveillance, treatment, and prevention are essential to mitigate the impact of multidrug-resistant infections in children.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
