Insights
Human parechovirus (HPeV) can cause severe illness in newborns, presenting with sepsis-like symptoms and neurological issues. Early HPeV detection is crucial for prompt diagnosis and management in infants.
Area of Science:
- Virology
- Neonatal Medicine
- Pediatric Infectious Diseases
Background:
- Human parechovirus (HPeV) is a known pathogen linked to central nervous system infections and sepsis-like illnesses in neonates.
- Common clinical manifestations include fever, seizures, irritability, rash, and encephalitis.
Observation:
- This report details 4 cases of full-term infants diagnosed with HPeV infection in October 2012.
- Median age at symptom onset was 15 days, with presentations of sepsis-like illness, gastrointestinal issues, and irritability.
- Two infants experienced respiratory distress, two developed skin rashes, and two required intensive care unit admission.
Findings:
- Laboratory findings included normal or mild inflammatory markers, normal or low white blood cell counts, and hepatitis.
- Notably, elevated muscular enzymes were observed for the first time in 3 of the affected infants.
- HPeV infection was confirmed via real-time PCR in cerebrospinal fluid and/or blood samples.
Implications:
- HPeV can lead to severe neonatal disease, necessitating evaluation in infants presenting with similar symptoms.
- Consideration of HPeV is important in cases of sudden infant death syndrome.
- This study highlights the potential severity of HPeV in neonates and introduces elevated muscular enzymes as a potential diagnostic marker.
Abstract:
Human parechovirus (HPeV) is associated with central nervous system infection and sepsis-like illness in newborn infants. The most frequent signs are fever, seizures, irritability, rash, and encephalitis. We report 4 cases of full-term infants with HPeV infection. They were admitted from home to the pediatric emergency unit of our hospital in October 2012. The median age at onset of symptoms was 15 days. They all developed sepsis-like illness with predominantly gastrointestinal disease and irritability. Two patients developed respiratory problems and 2 a skin rash (concerning only the extremities for one). Two patients required hospitalization in an intensive care unit. There was normal or mild inflammatory syndrome, normal white blood cell or mild leukopenia, hepatitis. We describe for the first time elevation of muscular enzymes in 3 of these patients. The diagnosis of HPeV infection was made by positive HPeV real-time PCR in cerebrospinal fluid (including the patient without pleocytosis) and/or blood. HPeV may cause severe disease in the neonatal period and patients presenting with such signs should be evaluated for HPeV. It also should be considered in sudden infant death syndrome.
