Diagnosis and Management of Occult Hepatitis B Virus Infection: A Short Review [PDF]

, 2015
Occult hepatitis B virus infection (OBI) is a challenging clinical entity. It is defined as the presence of viral DNA in the liver or serum of subjects who test negative for the hepatitis B surface antigen.

Occult hepatitis B in patients on hemodialysis: a review

Annals of Hepatology, 2013
The hepatitis B virus (HBV) is one of the most frequently transmitted agents in dialysis units. Occult hepatitis B is characterized by HBV infection without detectable surface antigen (HBsAg) in the patient’s serum, a positive or negative HBV DNA marker ...

Hepatitis B in Organ Transplantation—Current Evidence and Clinical Gaps

Transplant Infectious Disease, EarlyView.
ABSTRACT Over the past several decades there have been significant advances in nucleos(t)ide analogue (NA) antiviral therapy for hepatitis B virus (HBV) and global expansion of primary prevention through immunization. Despite this, HBV remains a leading cause of chronic liver disease globally, affecting over 250 million people.

Hepatitis B virus in silvery gibbons (Hylobates moloch) [PDF]

, 2004
This research investigated a number of issues regarding hepatitis B virus (HBV) in the silvery gibbon (Hylobates moloch). Due to the relatively recent discovery of the virus in nonhuman primate populations, specific knowledge of the biological behaviour ...

Geographic and species association of hepatitis B virus genotypes in non-human primates [PDF]

, 2003
Infection with hepatitis B virus (HBV) has been detected in human populations throughout the world, as well as in a number of ape species (Pan troglodytes, Gorilla gorilla, gibbons [Nomascus and Hylobates species] and Pongo pygmaeus).

Hepatitis B virus infection with high HBsAg and undetectable DNA levels in untreated blood donors: Viral mechanisms and transfusion safety implications

Transfusion, EarlyView.
Abstract Background Blood donor screening occasionally identifies individuals with high HBV surface antigen (HBsAg) levels despite undetectable or extremely low HBV DNA. Molecular basis and transfusion risk of this discordant profile remain unclear. Study Design and Methods Seventy‐five blood donors with HBsAg >100 IU/mL and undetectable or very low ...

PREVALENCE OF OCCULT HEPATITIS B INFECTION IN IRANIAN CANCER PATIENTS BEFORE CHEMOTHERAPY TREATMENT

Arquivos de Gastroenterologia
Background Occult hepatitis B infection is characterized by negative hepatitis B surface antigen (HBsAg) and also detectable hepatitis B virus (HBV) -DNA, with or without hepatitis B core antibody (anti-HBc).

Primary seronegative but molecularly evident hepadnaviral infection engages liver and induces hepatocarcinoma in the woodchuck model of hepatitis B. [PDF]

PLoS Pathogens, 2014
Hepadnavirus at very low doses establishes in woodchucks asymptomatic, serologically undetectable but molecularly evident persistent infection. This primary occult infection (POI) preferentially engages the immune system and initiates virus-specific T ...

Integrative characterization of human hepatocellular carcinoma‐derived organoids and their HBV‐associated biology

Clinical and Translational Medicine, Volume 16, Issue 10, October 2026.
20 HCC‐derived organoids, three adjacent non‐tumour tissue‐derived organoids, and 12 HCC‐derived cell lines from 20 patients were established and biobanked. Integrative analyses combining drug screening, whole‐exome sequencing, and RNA sequencing revealed molecular subtypes and identified candidate determinants of lenvatinib response.

A common HLA-DPA1 variant is associated with hepatitis B virus infection but fails to distinguish active from inactive Caucasian carriers [PDF]

, 2012
Background and Aims: Chronic infection with the hepatitis B virus (HBV) is a major health issue worldwide. Recently, single nucleotide polymorphisms (SNPs) within the human leukocyte antigen (HLA)-DP locus were identified to be associated with HBV ...
