Genetic variation of occult hepatitis B virus infection

World Journal of Gastroenterology, 2016
Occult hepatitis B virus infection (OBI), characterized as the persistence of hepatitis B virus (HBV) surface antigen (HBsAg) seronegativity and low viral load in blood or liver, is a special form of HBV infection. OBI may be related mainly to mutations in the HBV genome, although the underlying mechanism of it remains to be clarified.

Successful Endoscopic Sealing of Gastric Perforation With Tissue Adhesive Following Endoscopic Treatment for Gastric Fundal Variceal Bleeding: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Gastric perforation after endoscopic treatment of gastric fundal variceal bleeding is extremely rare. In carefully selected patients with early, small perforations and limited peritoneal contamination, endoscopic tissue adhesive injection combined with conservative management may provide a feasible nonsurgical rescue strategy.

Hepatitis B vaccination in the Columbian Amazon : effectiveness and factors influencing vaccine coverage [PDF]

A vaccination coverage survey was carried out in the Colombian Amazon, a former high endemic area for hepatitis B, involving 3573 children less than II years old. It was carried out in Leticia, Puerto Narifio, and Araracuara, both urban and rural areas.

Occult Hepatitis B Virus Infection

Annals of Clinical and Analytical Medicine, 2013
Occult hepatitis B virus infection (OHB) is defined as presence of Hepatitis B Virus (HBV) deoxyribonucleic acid in blood or tissues with undetectable hepatitis B surface antigen, outwith the preseroconversion window period. Several possibilities have been hypothesized as the mechanisms of OHB.

Occult hepatitis B infection and transfusion-transmission risk

Transfusion Clinique et Biologique, 2017
Advances in serology and viral nucleic acid testing (NAT) over the last decades significantly reduced the risk of transfusion-transmitted hepatitis B virus (HBV). The combination of HBsAg testing and NAT efficiently prevents the majority of HBV transmission.
