Hepatitis B surface antigen, core-related antigen and HBV RNA: Predicting clinical relapse after NA therapy discontinuatio

Completed
Conditions
To evaluate the HBV off-therapy relapse rate after discontinuation of NA. To determine the correlation of the new seromarkers to predict the HBV off-therapy relapse of non-cirrhotic chronic hepatiti

Brief Summary

The combined hepatitis B core-related antigen and hepatitis B virus RNA assays at end of treatment were highly predictive of subsequent clinical relapse. These novel biomarkers could potentially be used to identify patients who could safely discontinue nucleos(t)ide analogue therapy.
