title: [Detection and antigenic distribution of hepatitis B virus in liver tissue and its relation to other serological markers of viral replication].
abstract: The aim of this work has been the production of specific monoclonal antibodies against HBV-antigens and their utilisation in order to study their distribution on liver tissue. The monoclonal antibodies anti-HBc and anti-HBs were obtained by the modified hybridoma technique. This study was performed on 50 patients affected by several chronic hepatopathies. For the detection of the antigens, avidin-biotin-peroxidase complex immunostaining was used. Both cytoplasmic and membranous HBsAg were detected in 15 out of 16 HBsAg+ patients; 8 of 12 HBsAg-/anti-HBc+ patients and 1 HBsAg-/antiHBc- patient. Cytoplasmic and nuclear HBcAg was observed in 12 of 16 HBsAg+ patients and 4 of 20 HBsAg- patients. Although the presence of serum HBsAg is an index of liver infection, in some HBsAg-/antiHB+ patients (20%) with undetectable levels of HBsAg, hepatic injury may be disclosed by the detection of other markers of active viral replication.
