Carbapenem-Resistant Enterobacteriaceae in Children, United States, 1999-2012

Insights

Carbapenem-resistant Enterobacteriaceae (CRE) infections are rising in US children, though still rare. Increases were noted in Enterobacter species, blood cultures, and ICUs, highlighting the need for molecular studies and prevention strategies.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Pediatric Epidemiology

Background:

  • Carbapenem-resistant Enterobacteriaceae (CRE) pose a growing public health threat.
  • Limited data exists on CRE epidemiology specifically within pediatric populations in the United States.

Purpose of the Study:

  • To determine the prevalence and trends of CRE infections in children aged 1-17 years.
  • To identify specific patient groups and isolate types with increasing CRE rates.

Main Methods:

  • Analysis of antimicrobial susceptibility data for Enterobacteriaceae isolates from 1999-2012.
  • Utilized The Surveillance Network-USA database, encompassing 300 laboratories.
  • Phenotypic identification of CRE based on established criteria.

Main Results:

  • Out of 316,253 analyzed isolates, 266 (0.08%) were identified as CRE.
  • CRE infection rates increased significantly in Enterobacter species, blood cultures, and ICU isolates between 1999-2000 and 2011-2012.
  • CRE occurrence in children, while increasing, remained lower than extended-spectrum β-lactamase-producing Enterobacteriaceae.

Conclusions:

  • CRE infections in children are increasing but remain uncommon.
  • Further molecular characterization and clinical epidemiology studies are crucial for effective prevention strategies in pediatric populations.

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...

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...

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...

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...

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Clinical Significance of Antibiotic Resistance01:25

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...
