Abstract

Vertical transmission of hepatitis C virus (HCV) is the main route of infection in children, occurring in few cases (five percent). Current recommendations for HCV screening include first anti-HCV testing at age > 18 months, reducing false positives and false negatives. Positive results must be confirmed by the presence of HCV RNA on two different occasions. To characterize the population of children born to HCV-positive mothers, to identify risk factors for perinatal HCV transmission and to improve the approach to HCV screening. The study was conducted in two phases. An analytic retrospective study enrolling children born to HCV-positive mothers between January 2002 and December 2006 was done, followed by a transversal analysis in order to repeat anti-HCV testing, in cases that didn't meet current recommendations for HCV screening and in those without any HCV screening. Fifty-nine children born to HCV-positive mothers in a total of 12 985 births were included, corresponding to a prevalence of 0,45%. A high rate of inadequate pregnancy surveillance, prematurity and low birth weight, mainly in children born to addicted mothers was found. A child with HCV infection without any risk factor for perinatal transmission was found. Amo...Continue Reading
