Insights

Vancomycin-resistant enterococci (VRE) infections occurred in 10.2% of previously VRE-colonized children in the PICU. Long hospital stays and glycopeptide use increased VRE infection risk.

Area of Science:

  • Infectious Diseases
  • Critical Care Medicine
  • Pediatrics

Background:

  • Vancomycin-resistant enterococci (VRE) colonization is a concern in pediatric intensive care units (PICUs).
  • Understanding VRE infection frequency and risk factors in colonized children is crucial for effective infection control.

Purpose of the Study:

  • To determine the incidence of vancomycin-resistant enterococci (VRE) infection in previously VRE-colonized children admitted to a pediatric intensive care unit (PICU).
  • To identify risk factors associated with the development of VRE infection among colonized pediatric patients.

Main Methods:

  • Prospective surveillance data from January 2010 to December 2014 in PICUs were reviewed.
  • A case-control study design was employed to analyze risk factors for VRE infection in VRE-colonized patients.
  • Logistic regression analysis was used to identify significant risk factors.

Main Results:

  • Out of 1,134 PICU admissions, 108 patients (9.5%) were colonized with VRE.
  • Systemic VRE infections developed in 11 of the 108 colonized patients (10.2%), including bloodstream infections and urinary tract infections.
  • Long hospital stay (≥30 days) and glycopeptide use post-colonization were significant risk factors for VRE infection (OR 5.76 and 12.8, respectively).

Conclusions:

  • VRE colonization poses significant risks for pediatric patients in intensive care settings.
  • Implementing stringent infection control measures is essential to prevent VRE colonization and subsequent infections.
  • Restricting irrational antibiotic use, particularly glycopeptides, in VRE-colonized patients is recommended to mitigate infection risk.

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Mechanism of Antibiotic Resistance in MRSA

Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
