Published: December 2017

Background And Objectives: According to the demographic health survey conducted in 2015, Egypt had 10% documented prevalence of anti-HBc positive patients aged 1-59 and 1% viremic patients amongst the population in the same age group, with a domination of genotype D. Several studies claimed the possible role of vitamin D deficiency in hepatitis B virus (HBV) replication and disease progression.

Patients And Methods: Serum vitamin D levels [25(OH D3] were assessed in 96 HBeAg negative non-cirrhotic chronic HBV patients and 25 healthy subjects classified as following: Group I: 48 chronic HBV patients with persistently normal ALT levels and HBV DNA level < 2000 IU/mL for ≥ 6 months; Group II: 48 chronic HBV patients with CHB with persistently elevated ALT and HBV DNA level ≥ 2000 IU/mL for ≥ 6 months; and Group III: 25 apparently healthy subjects with normal liver enzymes and negative hepatitis viral markers were taken as the control group.

Results: Vitamin D was much more deficient in group II than in group I and group III being 11.55 ± 3.97 ng/mL, 15.03 ± 3.45, 27.00 ± 6.76 ng/mL ( < 0.001), respectively, and a strong negative correlation was observed between vitamin D levels and HBV DNA levels ( = 0.043) in groups I and II.

Conclusion: The current study showed high HBV DNA replication in patients with vitamin D deficiency suggesting the antimicrobial immunomodulatory role of vitamin D.

Cancer vaccines, crucial in the immunotherapeutic landscape, are bifurcated into preventive and therapeutic types, both integral to combating oncogenesis. Preventive cancer vaccines, like those against HPV and HBV, reduce the incidence of virus-associated cancers, while therapeutic cancer vaccines aim to activate dendritic cells and cytotoxic T lymphocytes for durable anti-tumor immunity. Recent advancements in vaccine platforms, such as synthetic peptides, mRNA, DNA, cellular, and nano-vaccines, have enhanced antigen presentation and immune activation.

To compare the effectiveness and safety profile of tenofovir amibufenamide (TMF) and tenofovir alafenamide (TAF), especially the effects on lipid metabolism in the treatment of chronic hepatitis B. A retrospective study was conducted on the virological response rate, biochemical response rate, renal function indicators, and lipid metabolism status of 159 cases with chronic hepatitis B (72 cases with TMF and 87 cases with TAF) after 48 weeks of antiviral treatment. The effects of the two drugs on lipid metabolism were further explored through cell and animal experiments.

Background: Recent evidence has indicated that the O-glycosylated PreS2 domain of the middle HBsAg is a distinguishing characteristic that allows the identification of HBsAg of HBV Dane particles and SVPs. This study's objective was to assess the changes in serum O-glycosylated HBsAg levels in CHB patients undergoing ETV or Peg-IFNα treatment.

Methods: Our retrospective study enrolled 86 patients with genotype C CHB.

Development of a sandwich-type electrochemical DNA sensor based on CeO/AuPt nanoprobes for highly sensitive detection of hepatitis B virus DNA.

To provide accurate diagnostic evidence for early hepatitis B virus (HBV) infection-related diseases, this study targeted HBV DNA as an analyte, where a sandwich-type electrochemical DNA sensor based on gold nanoparticles/reduced graphene oxide (Au NPs/ERGO) and cerium oxide/gold-platinum nanoparticles (CeO/AuPt NPs) was constructed. Au NPs/ERGO composite nanomaterials were first synthesized on the surface of a glass carbon electrode using electrochemical co-reduction, which significantly improved the specific surface area and electrical conductivity of the electrode. Further specific hybridization of target HBV-DNA was performed by combining capture probe DNA (S1-DNA) bound to AuNPs/ERGO with CeO/AuPt modified signal probe DNA (S2-DNA).

Prediction of cccDNA dynamics in hepatitis B patients by a combination of serum surrogate markers.

Quantification of intrahepatic covalently closed circular DNA (cccDNA) is a key for evaluating an elimination of hepatitis B virus (HBV) in infected patients. However, quantifying cccDNA requires invasive methods such as a liver biopsy, which makes it impractical to access the dynamics of cccDNA in patients. Although HBV RNA and HBV core-related antigens (HBcrAg) have been proposed as surrogate markers for evaluating cccDNA activity, they do not necessarily estimate the amount of cccDNA.
