The event of mutations in the surface antigen gene of hepatitis B virus (HBV) results in
undetectable hepatitis B surface antigen with positive/negative anti-hepatitis B core (anti …

Chronic hepatitis B virus (HBV) infection is a complex clinical entity frequently associated
with cirrhosis and hepatocellular carcinoma (HCC). The persistence of HBV genomes in the …

BACKGROUND: The role of occult hepatitis B virus infection as a cause of liver disease is
still debated although many studies found a higher prevalence of this condition in subjects …

The development of sensitive assays to detect small amounts of hepatitis B virus (HBV) DNA
has favored the identification of occult hepatitis B infection (OBI), a virological condition …

BACKGROUND: Occult hepatitis B (HBV) has been reported in numerous clinical settings,
but it remains unclear whether occult HBV contributes to liver damage. Given that typical …

Aim: Recent studies have suggested that an occult hepatitis B virus (HBV) infection negative
for HBsAg but positive for HBV‐DNA contributes to hepatocellular carcinoma (HCC) …

Occult hepatitis B infection is characterized by hepatitis B virus (HBV) DNA in the serum in
the absence of hepatitis B surface antigen (HBsAg). We assessed occult HBV infection …

Background Occult hepatitis B virus infection (OBI) frequently occurs in patients with chronic
hepatitis C (CHC) infection, but the influence of OBI on CHC outcome is still uncertain. The …

Coinfection with other hepatitis viruses modifies the viral profile in serum and leads to more
liver damage and more rapid progression during the course of hepatitis C virus infection …

Background: The association and profile of surface gene mutations with viral genotypes
have been studied in patients with chronic hepatitis B virus (HBV) but not in subjects with …
