Abstract
Human parechovirus-3 (HPeV-3) has been reported to cause a sepsis-like illness in
neonates and young infants. We experienced the occurrence of HPeV-3 infection in nine
neonates and young infants (eight boys, one girl; aged 14–52 days, median 31 days).
They were admitted to our hospital with the chief complaints of fever persisting for
3–5 days (median 4 days) and lethargy. Five infants presented with abdominal distension
and six had a rash (including acral reddening), as was previously reported with this
viral infection. Abdominal distension with navel protrusion and acral reddening during
the course were characteristic. Laboratory data were characterized by elevated values
for serum AST, LDH, FDP, D-dimer, ferritin, soluble IL-2 receptor, triglyceride, choline
esterase, and urinary β2-microglobulin. Two of our nine patients presented with a hemophagocytic lymphohistiocytosis
(HLH)-like illness and required specific therapy. These data suggest that HPeV-3 is
an important virus that can cause hypercytokinemia, which sometimes leads to HLH,
and systemic inflammatory response syndrome in neonates and young infants.
