Marzani, Constantino De Giacomo, Daniel Alagille – 1 January 1985 – The prevalence of intrahepatic delta antigen and/or anti‐delta antibody was retrospectively investigated in 102 children with chronic HBsAg‐positive hepatitis who were seen consecutively in three medical institutions between 1974 and 1982. Delta infection markers were found in 13 patients (12.7%) who exhibited high serum titers of anti‐delta antibody; intrahepatic delta antigen was detected in ten.
