ABSTRACT
Several national and international guidelines have been published in the last years
focusing on the problem of how to best treat patients with chronic hepatitis B virus
(HBV) infection. Therapy with interferon or nucleos(t)ide analogues has been shown
to be most effective in suppressing HBV deoxyribonucleic acid (DNA) levels and preventing
fibrosis progression herby also reducing the risk of hepatocellular carcinoma (HCC).
However even suppression of viral replication below the limit of detection does not
prevent HCC development although fibrosis can be stopped. Thus, improvement of therapeutic
strategies and the establishment of more sensitive markers that may help to decide
when therapy should be initiated and stopped remain important goals in hepatitis research.
The present review discusses several major issues in this respect such as strategies
to identify the optimal time point for treatment indication and end of therapy. It
also concentrates on questions and queries that have to do with the interpretation
of viral parameters like HBsAg quantification, HBV genotypes, and HBeAg, or the characterization
of risk patients prone to develop fatal sequel of the HBV infection.
KEYWORDS
