Objectives.  To estimate the hepatitis C virus (Hepatitis C Virus) vertical transmission rate, the effect of potential risk factors, and the pattern of Hepatitis C Virus antibody response and viremia in Hepatitis C Virus-infected infants.

Study Design.  The Mothers and Infants Cohort Study enrolled both human immunodeficiency virus (HIV)-seropositive and HIV-seronegative pregnant women at five obstetric clinics in New York City in a prospective cohort study between January 1986 and January 1991. Hepatitis C Virus-infected mothers and their 122 offspring were followed-up for a minimum of 12 months for evidence of Hepatitis C Virus infection as determined by persistent Hepatitis C Virus antibodies or detection of Hepatitis C Virus RNA by reverse transcription polymerase chain reaction. Comparisons among groups for categorical variables were performed using the Fisher's exact test.

Results.  Seven (6%; 95% confidence interval, 2%-11%) of the 122 infants were Hepatitis C Virus-infected. There was a tendency for increased risk of transmission with maternal viral and obstetrical factors, such as coinfection with HIV (7% vs 4%), high HIV viral load (13% vs 6%), Hepatitis C Virus viremia (8% vs 3%), vaginal delivery (6% vs 0%), and female gender of offspring (8% vs 3%), although none of the associations reached statistical significance. After loss of maternal antibody, Hepatitis C Virus antibody seroconversion occurred at a mean age of 26 months in 3 HIV-coinfected infants compared with 7 months of age in 4 Hepatitis C Virus-infected HIV-uninfected infants. Serial samples showed that Hepatitis C Virus RNA persisted in 6 infants for at least 18 to 54 months.

Conclusions.  Our study is in accordance with other studies that have shown low overall Hepatitis C Virus vertical transmission risk and a trend toward higher risk with maternal risk factors such as HIV-coinfection or Hepatitis C Virus viremia. A delay in infant Hepatitis C Virus antibody response may be associated with HIV coinfection although larger studies are needed to confirm these findings.

Key words: hepatitis C virus, human immunodeficiency virus, vertical transmission, children.
