title: [Hepatitis B with a fatal outcome in a 3-month-old infant of a healthy chronic carrier mother].
abstract: A 81 day old male infant developed an acute hepatitic failure and died shortly thereafter. Determinations of HBs antigen and antibody (AB) and HBeAg and AB were performed in the parents and sibling of the infected child. The mother and a sister were an asymptomatic carrier of HBsAg, the first HBeAg positive and the second HBeAB positive. An elder sibling was HBsAg and HBeAg positive in this serum. The father was anti-HBs positive. In the family of the sister, the man and two childs were HBsAg and anti-HBsAB negative. A new baby in the family of the propositus born and a combination of HB vaccine and HBIg (hepatite B immuno-globulin) was started at birth. Unfortunately the child died of S.D.I.S. (Sudden Death Infant Syndrome). The HB vaccine was immuno-genetic in this infant and the anti-HBs in the immuno-globulin M (IgM) was positive as in several adults controls. This case allow us to discuss vertical transmission of hepatitis B, the clinical aspect of neonatal hepatitis and the preventing HB infection by combinaison of HB vaccine and HBIg.
