Insights

Enterovirus infections in children are usually mild but can cause severe issues in infants and newborns. Current treatments are limited, with research exploring immunoglobulins, immunization, and anti-proteases.

Area of Science:

  • Pediatric Infectious Diseases
  • Virology
  • Neonatal Medicine

Context:

  • Enterovirus infections, including echoviruses and coxsackie viruses, are common in childhood.
  • While often benign, these infections pose significant risks in infants and neonates, potentially causing severe neurological or cardiac complications.
  • Distinguishing enterovirus infections from bacterial infections in neonates is clinically challenging.

Purpose:

  • To review the clinical presentation, diagnosis, and potential therapeutic strategies for enterovirus infections in pediatric populations.
  • To highlight the specific risks and diagnostic difficulties associated with enteroviruses in neonates.
  • To discuss emerging therapeutic avenues for enterovirus infections.

Summary:

  • Enterovirus infections in children present with diverse, non-specific symptoms, generally benign except for poliovirus.
  • Severe neurological and cardiac lesions can occur in infants, and neonatal infections mimic bacterial sepsis, with maternal transmission posing risks.
  • Diagnosis relies on viral cultures and PCR; effective antiviral drugs are lacking, but intravenous immunoglobulins, immunization, and anti-proteases are under investigation.

Impact:

  • Informing clinicians about the varied clinical spectrum of enterovirus infections in children.
  • Improving diagnostic approaches and early recognition of severe cases in infants and neonates.
  • Guiding future research and development of effective treatments for enterovirus infections.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
Bacterial Gastroenteritis01:18

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 receptor...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
