BACKGROUND: Therapy in chronic hepatitis B (CHB) patients aims at improving their survival by preventing disease progression to cirrhosis and its complications. Entecavir (ETV) is currently a first line therapeutic agent recommended for the treatment of CHB. Our aim was to evaluate the long term outcome of a cohort of CHB patients treated with ETV. METHODS: Thirty-four patients treated with ETV for at least 6 months were included in this study. The virologic response was determined by the dosage of serum HBV-DNA, HBsAg, HBeAg, anti-HBs and anti-HBe antibodies...

The global prevalence of liver cancer is rapidly rising, mostly as a result of the amplified incidence rates of viral hepatitis, alcohol abuse and obesity in recent decades. Treatment options for liver cancer are remarkably limited with sorafenib being the gold standard for advanced, unresectable hepatocellular carcinoma but offering extremely limited improvement of survival time. The immune system is now recognised as a key regulator of cancer development through its ability to protect against infection and chronic inflammation, which promote cancer development, and eliminate tumour cells when present...

Hepatitis C Virus (HCV) infects 2% of the world's population and is the leading cause of liver disease and liver transplantation. It poses a serious and growing worldwide public health problem that will only be partially addressed with the introduction of new antiviral therapies. However, these treatments will not prevent re-infection particularly in high risk populations. The introduction of a HCV vaccine has been predicted, using simulation models in a high risk population, to have a significant effect on reducing the incidence of HCV...

BACKGROUND: An association between hepatitis C virus (HCV) and type 2 diabetes (T2D) is supported by numerous epidemiologic studies. We hypothesized that HCV could infect human pancreatic islet cells in vitro. METHODS: Measures of HCV RNA synthesis and protein production were used to evaluate HCV infection of pancreatic islets recovered from human donors. RESULTS: Significant co-staining of insulin and the HCV entry factor CD81 was observed in pancreatic islets...

Liver cancer is the sixth most common cancer (fourth in men and sixth in women) and the second largest cause of cancer mortality in South Korea. The crude incidence rate of liver cancer was 31.9/100,000 (47.5/100,000 in men and 16.2/100,000 in women) and the age-standardized incidence rate was 19.9/100,000 (32.4/100,000 in men and 8.8/100,000 in women) in 2014. The crude incidence rate increased from 1999 to 2011 and thereafter showed a subtle decreasing tendency. The crude prevalence rate was 113.6/100,000 (170...

BACKGROUND & AIMS: GS-9620, an oral agonist of toll-like receptor 7 (TLR7), is in clinical development for the treatment of chronic hepatitis B (CHB). GS-9620 was previously shown to induced prolonged suppression of serum viral DNA and antigens in the chimpanzee and woodchuck models of CHB. Here we investigated the immunomodulatory mechanisms underlying these antiviral effects. METHODS: Archived liver biopsies and paired PBMC samples from a previous chimpanzee study were analyzed by RNA-Seq, qRT-PCR, immunohistochemistry (IHC) and in situ hybridization (ISH)...

Evidence documenting the global burden of disease from viral hepatitis was essential for the World Health Assembly to endorse the first Global Health Sector Strategy (GHSS) on viral hepatitis in May 2016. The GHSS on viral hepatitis proposes to eliminate viral hepatitis as a public health threat by 2030. The GHSS on viral hepatitis is in line with targets for HIV infection and tuberculosis as part of the Sustainable Development Goals. As coordination between hepatitis and HIV programs aims to optimize the use of resources, guidance is also needed to align the strategic information components of the 2 programs...

BACKGROUND AND AIM: Chronic hepatitis C (HCV), particularly genotype 1, is associated with insulin resistance (IR) and diabetes. We evaluated the impact of HCV clearance by all-oral direct-acting antiviral (DAAs) treatments on IR and glycemic control. METHODS: Included in this prospective case-control study were 133 consecutive HCV-genotype 1 patients with advance liver fibrosis (F3-F4) without type 2 diabetes. Sixty-eight treated with DAAs and 65 untreated. Liver fibrosis was assessed by transient elastography...

Hemophilia A (coagulation factor VIII deficiency) is a debilitating genetic disorder that is primarily treated with intravenous replacement therapy. Despite a variety of factor VIII protein formulations available, the risk of developing anti-dug antibodies ("inhibitors") remains. Overall, 20-30% of patients with severe disease develop inhibitors. Current clinical immune tolerance induction protocols to eliminate inhibitors are not effective in all patients, and there are no prophylactic protocols to prevent the immune response...

In this study, an in vitro infection model for the hepatitis delta virus (HDV) was used to evaluate the antiviral effects of phosphorothioate nucleic acid polymers (NAPs) and investigate their mechanism of action. The results show that NAPs inhibit HDV infection at less than 4 micromolar concentrations in cultures of differentiated human hepatoma cells. NAPs were shown to be active at viral entry, but inactive post entry on HDV RNA replication. Inhibition was independent of the NAPs nucleotide sequence, but dependent on both size and amphipathicity of the polymer...

Malaysia is a country where an estimated 1 million people are chronically infected with hepatitis B virus (HBV) and an estimated 2.5% of the adult population are positive for antibody to hepatitis C virus (HCV). Effective nationwide vaccine coverage seems to be a highly effective measure to prevent new HBV infection. Treatment of HCV infection is also a regular practice in Malaysia. These measures highlight the possibility to reach the World Health Organization elimination target by 2030. To achieve this target, the Health Ministry and other nongovernmental organizations, such as My Commitment to Cure (MyC2C) are working together to develop a strategic road map to reach the global elimination target in Malaysia by 2030...

In Japan, the estimated number of chronic hepatitis B virus infections was 1.1 to 1.4 million, and that of chronic hepatitis C virus was 1.9 to 2.3 million in 2000. The mortality of hepatocellular carcinoma had been increasing and hit the peak at around 2002, which subsequently started to decrease. Japan has a national action plan for addressing viral hepatitis called Basic Act on Hepatitis Measures, established in 2009. In 2011, basic guidelines for promotion of control measures for hepatitis were issued, comprising nine principles in order to promote measures to prevent hepatitis B and C...

This report contains new and follow-up metric data relating to the eight main recommendations of the Lancet Standing Commission on Liver Disease in the UK, which aim to reduce the unacceptable harmful consequences of excess alcohol consumption, obesity, and viral hepatitis. For alcohol, we provide data on alcohol dependence, damage to families, and the documented increase in alcohol consumption since removal of the above-inflation alcohol duty escalator. Alcoholic liver disease will shortly overtake ischaemic heart disease with regard to years of working life lost...

Hepatitis C virus (HCV) is the etiological agent of chronic hepatitis C and a major cause of liver cirrhosis and hepatocellular carcinoma. Only a minority of infected individuals can clear the virus spontaneously. The knowledge of the determinants of virus clearance would allow the development of effective methods preventing its further spread and optimizing treatment regimens. Viral factors associated with spontaneous virus clearance in the acute phase of infection, such as HCV genotype, virus heterogeneity, and the impact of viral proteins on the immune system have been characterized...

Hepatitis B virus (HBV) immunization has been effectively preventing chronic HBV infection with >90% efficacy in countries with universal neonatal immunization. Perinatal mother-to-infant transmission of HBV remains the major cause of chronic HBV infection despite immunization. Maternal hepatitis B e-antigen (HBeAg) and high viral load have been noted to be the most important risk factors for transmission. In recent years, short-term antiviral therapy for pregnant women in the third trimester has been shown to be highly effective in reducing 90% of vaccine failure in children...

BACKGROUND: Initial serological testing for chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection is conducted using either rapid diagnostic tests (RDT) or laboratory-based enzyme immunoassays (EIA)s for detection of hepatitis B surface antigen (HBsAg) or antibodies to HCV (anti-HCV), typically on serum or plasma specimens and, for certain RDTs, capillary whole blood. WHO recommends the use of standardized testing strategies - defined as a sequence of one or more assays to maximize testing accuracy while simplifying the testing process and ideally minimizing cost...

BACKGROUND AND AIMS: In Switzerland, the prevalence of hepatitis C virus (HCV) among people who inject drugs (PWID) has been decreasing owing to active harm reduction efforts and an aging population. Recent advances in HCV therapeutics may provide an opportunity to direct treatment to high-risk populations, with a goal of reducing HCV prevalence and preventing new infections. In order to guide these efforts, the current project was undertaken with the following aims: (1) to develop a simple model to estimate the number of new HCV infections using available data on PWID; (2) to examine the impact of intervention strategies (prevention and treatment) on new and total HCV infections among PWID...

Hepatitis E virus (HEV) infection usually causes acute hepatitis and has a self-limiting progression. The patients often recover within 6 months with good prognosis. Recent studies have found that HEV infection may become chronic in special situations, which manifests as persistent liver function abnormalities for at least 6 months after acute HEV infection and the presence of viral nucleic acid in serum, feces, and/or liver tissue. Chronicity of HEV infection mainly occurs in immunocompromised patients, and it is rare but very dangerous in clinical practice...

Liver disease remains a leading cause of mortality worldwide despite recent successes in the viral hepatitis field because increases in alcohol consumption and obesity are fueling epidemics of chronic fatty liver disease for which there are currently no effective medical therapies. About 20% of individuals with chronic liver injury ultimately develop end-stage liver disease due to cirrhosis and hence, treatments to prevent and reverse cirrhosis in individuals with ongoing liver injury are desperately needed...
