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.
Abstract:
Enterovirus infections in childhood (echoviruses, coxsackie viruses A and B, unclassified enteroviruses) are varied, nonspecific and benign (except for poliovirus infections). However, in infants, they may lead to severe neurological or cardiac lesions. In neonates, enterovirus infections are difficult to distinguish from late-onset bacterial infection. Maternal-fetal or postnatal transmission can induce early spontaneous abortions or severe neonatal infections. Diagnosis is usually based on viral cultures and, in recent years, on PCR techniques. At the present time, no potential effective drug is available: intravenous immunoglobulins, immunization or anti-proteases may be of interest.
