Direct-acting antiviral agents (DAA) for hepatitis C virus (HCV) are not effective for hepatitis B virus (HBV), which may be suggestive of reactivation of anti-HBe hepatitis during interferon (IFN)-free DAA therapy in HBV/HCV co-infected patients with inactive HBV. A 69-year-old male patient was diagnosed with chronic hepatitis due to HBV/HCV co-infection with serum levels of alanine aminotrans...
The role of peripheral blood mononuclear cells (PBMCs) in HBV intrauterine infection is not fully defined. Particularly the origin of PBMCs in HBV-infected neonates remains to be addressed. We carried out a population-based nested case-control study by enrolling 312 HBsAg-positive mothers and their babies. PBMC HBV DNA as well as serum HBsAg and HBV DNA was tested in cohort entry samples. Total...
Occult hepatitis B in Mexican patients with HIV, an analysis using nested polymerase chain reaction.
Hepatitis B virus infection (HBV) with undetectable levels of HBsAg, has been named occult HBV infection and observed in immunosuppressed patients. The aim of this study was to determine the frequency of occult HBV infection in patients with HIV from the West of México, using a combination of serological markers and nPCR. Thirty eight HIV/AIDS patients, 32 men (84.2%) and 6 (5.8%) women, withou...
BACKGROUND/AIMS We investigated the frequency of occult hepatitis B virus (HBV) infection in anti-hepatitis C virus (HCV)-positive individuals and the effects of occult HBV infection on the severity of liver disease. METHODS Seventy-one hepatitis B virus surface-antigen (HBsAg)-negative patients were divided according to their HBV serological status into groups A (anti-HBc positive, anti-HBs ...
Retinoic acid-inducible gene-I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5) belong to the RIG-I-like receptors family of pattern recognition receptors. Both RIG-I and MDA5 have been shown to recognize various viral RNAs, but whether they mediate hepatitis B virus (HBV) infection remains unclear. In this study, we demonstrated that the expression of MDA5, but not RIG-I, was incr...
Hepatitis B virus (HBV) infection remains an endemic disease in most parts of the world despite available prophylactic vaccines. Non-Hodgkin's lymphoma is the most common hematological malignancy, and certain patients undergoing therapy are at increased risk of HBV reactivation. Rituximab, a monoclonal antibody, is well studied in HBV reactivation, but newer agents have been implicated as well....
There is a wide range in prevalence of hepatitis B virus (HBV) infection and HBV immunization programs between different regions. Hepatitis B is a vaccine preventable disease yet is still endemic in the majority of countries in Asia. Despite the decreasing global prevalence of chronic HBV infection, there is still considerable risk of HBV infection among international travelers to high endemic ...
BACKGROUND We compared the AdvanSure hepatitis B virus real-time polymerase chain reaction (AdvanSure HBV) kit with three other HBV DNA quantification assays and evaluated its performance. METHODS The AdvanSure HBV real-time PCR assay was compared with the Abbott RealTime HBV Quantification Kit, the COBAS TaqMan HBV Test, and the VERSANT HBV branched DNA 3.0 assay. The precision, linearity, a...
BACKGROUND To investigate the risk of hepatitis B virus (HBV) reactivation in rheumatoid arthritis (RA) patients with HBV carrier state during treatment of disease-modifying antirheumatic drugs (DMARDs) and the use of antiviral prophylaxis in real-world clinical practice. METHODS Consecutive RA patients with HBV carrier state were included. Clinical data including liver evaluation, HBV infect...
Three genome-wide association studies (GWAS) have been conducted on the genetic susceptibility of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), two of which consistently identified tagging single nucleotide polymorphisms (SNPs) around HLA-DQ/DR. In contrast, large multi-centre association studies between HBV genotype, mutations and the risk of HCC are relatively rare, and thei...
