Chronic viral hepatitis is discussed here in a multidisciplinary
approach. The editors' goal was to assemble contributions from
clinicians, laboratory physicians, epidemiologists, pathologists, and
molecular biologists to provide a synopsis of all the important aspects
of this disease. A key element in the chronic evolution of viral
hepatitis is the persistent coexistence of a cytotoxic immune response
and viral gene expression which is discussed in eleven articles on
immune pathogenesis. The oncogenicity of hepatitis B virus at the
molecular level and of hepatitis C virus at the epidemiological level is
discussed in two chapters. The application of PCR for the detection of
hepatitis viruses and their variants is a major topic of both practical
and theoretical interest. The clinical significance of newly developed
serological assays for diagnosis and prevention is discussed in depth by
specialists from clinics, transfusion centers and virological
laboratories. The therapy of chronic viral hepatitis is still
unsatisfactory, but some slow progress is described in several articles.
Furthermore, the volume has a special chapter on the often neglected
topic of chronic hepatitis in childhood.
