The emergence and takeover of hepatitis B virus (HBV) variants carrying mutation (s) in the
preS/S genomic region is a fairly frequent event that may occur spontaneously or may be the …

One third of the global population has been acutely infected with hepatitis B virus (HBV);
less than 1% of patients with acute infection will develop fulminant hepatitis. 1 Approximately …

Background Hepatitis B virus (HBV) infections in patients who lack detectable hepatitis B
surface antigen (HBsAg) are called occult infections. Although such infections have been …

Background & Aims: The interactions among pre-S deletion, precore (PC) mutation, and
basal core promoter (BCP) mutation in various stages of chronic hepatitis B virus (HBV) …

The genetic variability of hepatitis B virus (HBV) represents a challenge for the sensitivity of
immunologic and molecular based assays. Based on sequence divergence in the entire …

Background & Aims: This longitudinal study investigated the interactions and roles of
hepatitis B virus (HBV) genotypes, pre-S deletions, and core promoter and precore …

Infection with hepatitis B virus (HBV) leads to a wide spectrum of clinical presentations
ranging from an asymptomatic carrier state to self-limited acute or fulminant hepatitis to …

Publisher Summary Although most living biological systems have developed intricate
mechanisms to keep the genetic information stable, many viruses, including hepatitis B virus …

Hepatitis B virus surface antigen (HBsAg) vaccination has been shown to be effective in
preventing hepatitis B virus (HBV) infection. The protection is based on the induction of anti …

Objective Among individuals with chronic hepatitis B, those with hepatitis B e-antigen
(HBeAg)-negative chronic hepatitis (CHB) can be difficult to distinguish from those with …
