This study aimed to estimate the disease burden of hepatitis E in a rural region in China. A total of 489 hepatitis E cases were reported according to a community-based survey in an active hepatitis surveillance system between 2008 and 2015, the questionnaire and record-review methods were constructed to evaluate the economic and health burden of hepatitis E virus infections from societal perspectives. All costs were converted to US$ in 2015. The age-standardized cumulative incidence rate was 107·9/100 000, and the median age-standardized annual incidence rate was 16·5/100 000...

The rate of transfusion-transmitted hepatitis E virus (HEV) in transplant recipients is unknown. We identified 60 HEV-positive solid organ transplant patients and retrospectively assessed their blood transfusions for HEV. Seven of 60 patients received transfusions; 3 received HEV-positive blood products. Transfusion is not the major route of infection in this population.

We compared the epidemiology of hepatitis A and hepatitis E cases in China from 1990-2014 to better inform policy and prevention efforts. The incidence of hepatitis A cases declined dramatically, while hepatitis E incidence increased. During 2004-2014, hepatitis E mortality rates surpassed those of hepatitis A.

Acute viral hepatitis is usually a self-limiting illness. However, it can lead to complications that can be life-threatening, such as acute liver failure. Glucose 6 phosphate dehydrogenase (G6PD) deficiency in the setting of acute viral hepatitis can lead to a massive hemolysis, manifesting as acute kidney injury and markedly raised bilirubin levels; although cases are rare. Here, we report such a case. The patient had a viral hepatitis E infection and presented with kidney injury requiring dialysis. Examination showed very high mixed hyperbilirubinemia due to massive intravascular hemolysis...

Hepatitis E virus (HEV) is the leading cause of enterically transmitted viral hepatitis globally. Of HEV's three ORFs, the function of ORF3 has remained elusive. Here, we demonstrate that via homophilic interactions ORF3 forms multimeric complexes associated with intracellular endoplasmic reticulum (ER)-derived membranes. HEV ORF3 shares several structural features with class I viroporins, and the function of HEV ORF3 can be maintained by replacing it with the well-characterized viroporin influenza A virus (IAV) matrix-2 protein...

The incidence of hepatitis E in Singapore appears to be increasing. A retrospective case-series study of patients diagnosed with hepatitis E in a tertiary hospital from 2009 to 2013 was conducted. Of 16 cases, eight (50%) were solid-organ transplant recipients (SOTRs), and 14 (88%) were found infected by genotype 3 hepatitis E virus (HEV-3). Bayesian inferences based on HEV subgenomic sequences from seven cases suggest that HEV-3 strains were introduced to Singapore as two principal lineages. Within limitations of the study, it can be inferred that one lineage, in the 3efg clade, emerged about 83 years ago, probably originating from Japan, whereas the other, in the 3abchij clade, emerged about 40 years ago, from the United States...

Hepatitis E virus is responsible for acute and chronic liver infections worldwide. Swine hepatitis E virus has been isolated in Brazil, and a probable zoonotic transmission has been described, although data are still scarce. The aim of this study was to investigate the frequency of hepatitis E virus infection in pigs from a small-scale farm in the rural area of Paraná State, South Brazil. Fecal samples were collected from 170 pigs and screened for hepatitis E virus RNA using a duplex real-time RT-PCR targeting a highly conserved 70nt long sequence within overlapping parts of ORF2 and ORF3 as well as a 113nt sequence of ORF2...

BACKGROUND: Symptomatic Hepatitis E virus (HEV) infection occurs in few infected subjects, and the risk factors are not completely known. AIMS: To explore the risk factors for adverse clinical outcomes in acute HEV infections. METHODS: A large retrospective study was conducted. The baseline characteristics, clinical outcomes, and laboratory data of 512 acute HEV infection cases were analysed using logistic regression models. RESULTS: All patients exhibited autochthonous sporadic HEV infections, and most were elderly...

Although Hepatitis E (HEV) is regarded asa self-limiting infection and anti-HEV antibodies seem toprotect against reinfection, its pathogenesis is not well established. We describe two cases of acute symptomatic HEV infection after Hepatitis C therapy in patients carrying anti-HEV IgG antibodies raising two major questions: reactivation or reinfection?

Although hepatitis E has emerged as a global health issue, there is limited knowledge of its infection biology and no FDA-approved medication is available. Aiming to investigate the role of protein kinases in hepatitis E virus (HEV) infection and to identify potential antiviral targets, we screened a library of pharmacological kinase inhibitors in a cell culture model, a subgenomic HEV replicon containing luciferase reporter. We identified protein kinase C alpha (PKCα) as an essential cell host factor restricting HEV replication...

An HIV-infected patient was diagnosed with acute hepatitis E infection in our hospital. An epidemiological inquiry was performed to collect demographic, food and animal exposure variables in order to identify the potential route of transmission. The patient reported that his family traditionally hunted wild boar for food. All family members were analysed for hepatitis E virus infection. Additionally, route of transmission by wild boar meat consumption and prevalence of HEV infection among wild boar from the same hunting area were investigated...

Hepatitis E virus (HEV) is a zoonotic virus that causes acute hepatitis in humans, and can be transmitted via the fecal-oral route. Pigs are considered to be a reservoir for this infection-mainly where the disease is not endemic. In a previous study conducted in Antioquia, which is a region in Colombia where the production and consumption of pork meat is higher than in the rest of the country, the presence of anti-HEV IgG-type antibodies was reported in slaughter-age pigs. Aiming to identify the HEV genotype circulating in swine, animal liver, and feces samples from five swine cattle slaughterhouses located in six different sub-regions of Antioquia were collected...

AIM: To examine the clinical features and risk factors for adverse outcomes in chronic hepatitis B (CHB) superimposed with hepatitis E virus (HEV). METHODS: This retrospective cohort study included 228 patients with acute HEV infection (showing clinical acute hepatitis symptomology and positivity for anti-HEV immunoglobulin M) with underlying CHB (confirmed by positivity for hepatitis B surface antigen and/or hepatitis B virus (HBV) DNA over 6 mo) who had been admitted to the Shanghai Public Health Clinical Center, which represents the regional tertiary hospital for infectious diseases in Shanghai city, China...

BACKGROUND: The concentrations of hepatitis B virus (HBV) DNA and surface antigen (HBsAg) are two critical virological variables to be monitored in chronic hepatitis B. HBsAg is derived from the HBV genome. Thus, higher HBV-DNA concentrations should implicate higher HBsAg levels. Nevertheless, the two variables do not manifest a simple linear relationship due to elusive host factor involvements. The aim of this study was to address the discrepancy of HBV DNA and HBsAg levels by a quantitative modeling of HBsAg concentrations...

BACKGROUND: Recent serological studies indicate that hepatitis E virus (HEV) is endemic in industrialised countries. The increasing trend in the number of autochthonous cases of HEV genotype 3 in Western European countries, stresses the importance to get insight in the exact routes of exposure. Pigs are the main animal reservoir, and zoonotic food-borne transmission of HEV is proven. However, infected pigs can excrete large amounts of virus via their faeces enabling environmental transmission of HEV to humans...

 Acute hepatitis E is becoming increasingly recognised in Europe with up to 40% of the population in Southern France being exposed to the virus, which is harboured in pigs. Patients with known liver disease may present with acute hepatitis E and present a diagnostic challenge. For example patients with autoimmune hepatitis (AIH) who are immunosuppressed and contract hepatitis E may be at increased risk of developing chronicity due to concurrent immunosuppression. Importantly, the diagnosis may be missed with the infection misdiagnosed as an autoimmune flare, and immunosuppression increased by the attending physician, thus enhancing the risk of chronicity of infection leading to progressive liver injury in immunocompromised patients...

:  Background. There are only few reports about travel-associated, imported tropical hepatitis E virus (HEV) genotype 1 infections within Western travellers. We describe the clinical course of a single outbreak of hepatitis E in a German travellers group returning from India and compare the results of two commercial HEV-seroassays. MATERIAL AND METHODS: After identifying hepatitis E in an index patient returning from a journey to India all 24 members of this journey were tested for anti-HEV-IgG and IgM using two commercial seroassays (Wantai and Mikrogen), for HEV-RNA by PCR and HEV-Ag by an antigen-assay (Wantai)...

BACKGROUND: The risk of hepatitis E virus (HEV) infection from blood transfusion has raised increasing concern in many countries. Several transfusion-transmitted cases have been described in the United Kingdom and Japan. The objective was to investigate the prevalence of HEV infection among Chinese blood donors and analyze the potential risk of HEV infection through blood transfusion in China. STUDY DESIGN AND METHODS: Major English and Chinese research databases were used as background research for the study of locations, years, and the number of HEV infections among blood donors in China...
