Is growth in the first 5 years of life unaffected in children with perinatally-acquired hepatitis C infection? Context: To identify the effect of vertical hepatitis C virus (HCV) infection or exposure on growth in childhood. Children (n=1203) born to HCV-infected mothers were followed up from birth prospectively in centers of the European Paediatric Hepatitis C virus Network. Z-scores compared height- and weight-for-age in HCV-infected and -uninfected children, adjusting for other factors using linear regression. We also quantified the effect of maternal chronic infection with HCV on childhood growth. There was no significant effect of vertical HCV infection on growth (height P=.223, weight P=.095) nor a significant effect of maternal chronic infection with HCV (height P=.733, weight P=.274). Prematurity and maternal injecting drug use were associated with a significant reduction in height (P < .001) and weight (P < .001) in all HCV-exposed children.

This population of HCV exposed infants has higher rates of maternal injecting drug use and prematurity than standard populations and so there are implications for growth of these children, but this is not a direct result of HCV infection or exposure to chronic maternal HCV infection. Final Decision: yes
