BACKGROUND: More than 240 million people are chronically infected by hepatitis B virus (HBV) worldwide. Envelope proteins play a crucial role in viral cellular entry and immune recognition. The loss of HBs antigen (HBsAg) correlated with a good clinical prognosis is rarely achieved with or without treatment (3-16%). OBJECTIVES: HBV envelope variability was investigated according to HBsAg persistence. STUDY DESIGN: The cohort consisted of 15 HBV genotype A-infected patients divided into "resolvers", with HBsAg clearance, and "non-resolvers", with HBsAg persistence and in subgroups: acute (n=5, AHBV) or chronic infection (n=4, CHBV) and HBV/HIV coinfection (n=6, CHBV/HIV)...

Hepatitis B virus (HBV) can invade the male germline, and sperm-introduced HBV genes could be transcribed in embryo. This study was to explore whether viral gene transcription is regulated by host genes. Embryos were produced by in vitro fertilization of hamster oocytes with human sperm containing the HBV genome. Total RNA extracted from test and control embryos were subjected to SMART-PCR, SSH, microarray hybridization, sequencing and BLAST analysis. Twenty-nine sequences showing significant identity to five human gene families were identified, with CSH2, EIF4G2, PCBD2, PSG4 and TTN selected to represent target genes...

BACKGROUND AND AIM: Recent studies have reported beneficial effects of specific probiotics on obesity. However, the difference in the anti-obesity effects of probiotics as single species and dual species is still uncertain. Therefore, we aimed to compare the efficacy of single and dual species of bacteria on markers of obesity in high-fat diet-induced obese rats. METHODS AND RESULTS: A total of 40 male Sprague-Dawley rats were assigned to one of five groups of varying diets as follows: standard diet, high fat diet (HFD), HFD supplemented with Lactobacillus casei strain Shirota, HFD supplemented with Bifidobacterium longum and HFD supplemented with a mixture of these two bacterial species...

International guidelines recommend lifelong nucleos(t)ide analogue (NA) treatment in individuals with chronic hepatitis B (CHB) infection who are hepatitis B e antigen (HBeAg) seronegative, because hepatitis B surface antigen (HBsAg) seroconversion is rarely achieved. However, after terminating therapy, sustained responses and HBsAg loss have been observed. Clinical characteristics identifying persons with favorable outcomes after discontinuing NA therapy have not yet been defined. This case series describes outcomes of 6 individuals with HBeAg-seronegative CHB infection without cirrhosis and low plasma levels of HBsAg who discontinued long-term NA treatment...

Fecal contamination of drinking water is associated with large hepatitis E virus (HEV) outbreaks of genotypes 1 and 2 in endemic areas. Sporadic transmission of HEV genotypes 3 and 4 in high-income countries has been associated with exposure to blood and animal contact. The objective of the study was to identify the risk factors for hepatitis E and the genotype(s) causing sporadic hepatitis E in Dhaka, Bangladesh. We selected, from a diagnostic center in Dhaka between November 2008 and November 2009, cases presenting with jaundice and anti-HEV IgM antibodies and age-matched controls were defined as those with no history of jaundice and normal blood test results...

REVIEW
Shaoli Lin, Yan-Jin Zhang
Hepatitis B virus (HBV) causes liver diseases that have been a consistent problem for human health, leading to more than one million deaths every year worldwide. A large proportion of hepatocellular carcinoma (HCC) cases across the world are closely associated with chronic HBV infection. Apoptosis is a programmed cell death and is frequently altered in cancer development. HBV infection interferes with the apoptosis signaling to promote HCC progression and viral proliferation. The HBV-mediated alteration of apoptosis is achieved via interference with cellular signaling pathways and regulation of epigenetics...

The purpose of antiviral therapy in chronic hepatitis B (CHB) is generally to achieve a decrease and ultimately disappearance of HBs antigen (HBsAg). Interferon (IFN) therapy of CHB appears to be less effective in Asian countries than in European countries, and the advantage of IFN and nucleotide(s) analog (NA) combination therapy has yet to be fully investigated. The present study focused on the factors associated with a decrease in HBs antigen following IFN monotherapy or IFN + NA combination therapy. A total of 35 patients with CHB who received IFN-based therapy (mean ± standard deviation age 36...

The gamma-glutamyl transpeptidase to platelet ratio (GPR) is a novel index to estimate liver fibrosis in chronic hepatitis B (CHB). Few studies compared diagnostic accuracy of GPR with other non-invasive fibrosis tests based on blood parameters. We analyzed diagnostic values of GPR for detecting liver fibrosis and compared diagnostic performances of GPR with APRI (aspartate aminotransferase-to-platelet ratio index), FIB-4 (fibrosis index based on the four factors), NLR (neutrophil-to-lymphocyte ratio), AAR (aspartate aminotransferase/alanine aminotransferase ratio) and RPR (red cell distribution width-to-platelet ratio) in HBeAg positive CHB and HBeAg negative CHB...

BACKGROUND: Mother-to-child transmission is still considered a major factor in the spread of hepatitis viruses. Nevertheless, epidemiological data on hepatitis B virus (HBV) and hepatitis C virus (HCV) in reproductive-age women are limited even in areas like the South of Italy where both viruses had been widespread. AIM: The aim of this study was to investigate the prevalence of HBV and HCV serum markers in a large cohort of pregnant women from Southern Italy. METHODS: Data concerning 7558 pregnant women consecutively admitted to an Obstetric Division of a Sicilian University Hospital over a six-year period (January 2010-December 2015) were retrospectively collected from clinical notes...

BACKGROUND: Adequate muscle relaxation is important for ensuring optimal conditions for intubation. Although acceleromyography of the adductor pollicis muscle is commonly used to assess conditions for intubation, we hypothesized that acceleromyography of the trapezius is more indicative of optimal intubating conditions. The primary outcome was the difference between both measurement sites with regard to prediction of good or acceptable intubating conditions. METHODS: Neuromuscular blockade after injection of rocuronium 0...

Diabetes mellitus (DM) is increasing in prevalence nationwide and in South Dakota, with an especially high prevalence in its American Indian population. Screening is not recommended for type 1 DM, but is for type 2 DM and pre-diabetes in certain populations. Fasting glucose, two-hour glucose tolerance test, or hemoglobin A1c are appropriate screening options. Treatment can include diabetic self-management education programs and medications. In addition to glycemic control, other cardiovascular risk factors must be reduced in these patients and specific testing and consultations should be performed to detect complications such as nephropathy or retinopathy...

INTRODUCTION: Little is known about hepatotoxicity in patients with schistosome and HIV co-infections. Several studies have reported increased liver enzymes and bilirubin levels associated with schistosome infection. We investigated whether HIV-infected adults on antiretroviral therapy who had S. mansoni co-infection had a higher prevalence of hepatotoxicity than those without. METHODOLOGY/PRINCIPAL FINDINGS: We determined the presence and grade of hepatotoxicity among 305 HIV-infected outpatients who had been on medium-term (3-6 months) and long-term (>36 months) antiretroviral therapy in a region of northwest Tanzania where S...
