title: Viral hepatitis B and Wiskott-Aldrich syndrome.
abstract: A 4-year-old boy affected by Wiskott-Aldrich syndrome had overt viral hepatitis B after repetitive blood transfusions. He was given immune serum containing HBs antibodies, with only transient improvement. The HBsAg titer decreased immediately after each administration of immune serum, but 2 days later it was higher than before. This effect could be explained by the presence of HBs antigen-HBs antibody complexes in the immune serum, not detected by the current testing procedure.
