To evaluate the clinical, biochemical, and virologic features associated with hepatitis C virus (HCV) infection acquired early in life from mothers with antibodies to HCV (anti-HCV).
Multicenter prospective-retrospective study in Italian children.
Two groups of children were investigated.
Group 1 included 14 infants, born to mothers with anti-HCV but without human immunodeficiency virus infection, who became seropositive for HCV RNA during the first year of life and were thus considered infected.
Group 2 included 16 children with chronic hepatitis C, aged 1 1/2 to 14 years, whose mothers were the unique potential source of infection.
Both groups were followed for 12 to 48 months.
Alanine transaminase (ALT), anti-HCV, and HCV RNA were investigated by the polymerase chain reaction on entry to the study and during follow-up.
All children in group 1 had anti-HCV throughout follow-up, and all had ALT abnormalities, ranging from 1.5 to 10.5 times the normal value during the first 12 months.
During further follow-up, 5 of 10 children had HCV RNA with abnormal ALT values, 3 had a return to normal of the ALT values but continued to have viremia, and 2 eventually had normal ALT values and clearance of HCV RNA.
Of the 16 children in group 2, all were free of symptoms and 62% had only slight ALT elevations ; 7 who underwent liver biopsy had histologic features of minimal or moderate hepatitis. (...)
