Abstract

AIM:

The human parechovirus (HPeV) is an increasingly recognised cause of sepsis and central nervous system infection in young infants for which there are limited long-term outcome data. We aimed to assess neurodevelopmental outcome and quality of life in infants following hospitalised HPeV infection.

METHODS:

This cohort study was a 12-month follow-up of infants who were hospitalised with confirmed HPeV infection at the Sydney Children's Hospitals Network during an outbreak in Sydney in 2013. Telephone interviews were conducted with parents/guardians. We administered standardised questionnaires, including: Ages and Stages Questionnaire (ASQ), Liverpool Outcome Score-follow-up, Pediatric Quality of Life Inventory(PedsQL) Infant scales and Short-Form health survey (SF-12).

RESULTS:

We followed up 46 of 79 infants (58%) aged between 12 and 16 months who had been hospitalised with HPeV infection; 19% showed significant concern in developmental attainment (ASQ3 score <2 standard deviation below population mean), and 50% showed some concern (<1 standard deviation below mean). ASQ3 developmental outcome was associated with the presence of neurodevelopmental sequelae (lower total Liverpool Outcome Score) and poorer health-related quality of life (HRQOL) in physical functioning (PedsQL physical component score), but not overall HRQOL (total PedsQL score) or parental HRQOL (SF-12 scores). No significant associations were identified between clinical or laboratory features during acute hospitalisation and adverse outcome on ASQ3.

CONCLUSIONS:

A high proportion of infants show developmental concern at 12-month follow-up post-hospitalisation with HPeV infection. Clinical features during hospitalisation were not associated with adverse outcomes at 12 months. These results suggest that careful follow-up of young infants hospitalised with HPeV disease may be warranted.
