|Title:||Mother-to-infant transmission of hepatitis C virus (HCV) in Brazil|
|Abstract:||Sixty-one women with anti-HCV antibodies, detected by a third-generation enzyme immunoassay (EIA3), were prospectively recruited for investigation of vertical HCV transmission during childbirth, at the University Hospital of the Catholic University of Campinas, Brazil, between January 1994 and July 1998. Six of the women presented coinfection with the human immunodeficiency virus type 1 (HIV-1). All of the 72 children born in this period were followed at least until they were 18 months of age. Analyses of anti-HCV, HCV RNA, and alanine aminotransferase were performed in a minimum of two blood samples during follow-up. One (2.4 per cent; 95 per cent CI, 2.2-7) of the 42 children born to HCV viremic mothers was both anti-HCV and HCV RNA-positive, with altered ALT levels. Passively transferred maternal anti-HCV antibodies became undetectable within 9-12 months. None of the nine infants born to HIV-1 infected mothers were infected either by HIV or HCV. Thus, the mother-infant HCV transmission rate is low and seems to be associated with maternal HCV RNA positivity.|
