Epidemiological studies found that hepatitis E virus genotype 3 (HEV-3) infection was associated with chronic hepatitis and cirrhosis in immunocompromised patients. Our study aimed to investigate the relationship between the host immunosuppressive status and the occurrence of HEV-related chronic hepatitis. Here we describe a successful experimental study, using cynomolgus monkeys previously treated with tacrolimus, a potent calcineurin inhibitor immunosuppressant, and infected with a Brazilian HEV-3 strain isolated from naturally infected pigs...

Pregnant women with acute viral hepatitis are at higher risk of morbidity and death than pregnant women with chronic viral hepatitis. The risk of death is highest with acute viral hepatitis E, and the rate of transmission to the baby may be highest with hepatitis B virus (HBV) infection. Managing viral hepatitis in pregnancy requires assessing the risk of transmission to the baby, determining the gestational age at the time of infection and the mother's risk of decompensation, and understanding the side effects of antiviral drugs...

Reclamation of wastewater (WW) for irrigation, after treatment represents a challenge that could alleviate pressure on water resources and address the increasing demand for agriculture. However, the risks to human health must be assessed, particularly those related to human enteric viruses that resist standard treatments in most wastewater treatment plants (WWTP). The risks associated with exposure to viral bioaerosols near WWTP and near agricultural plots irrigated with WW are poorly documented. The objectives of this study were to 1) better characterize human enteric viruses found in bioaerosols near a "standard WWTP" and over fields irrigated with treated WW and 2) propose a numeric model to assess the health risk to populations located close to the irrigated areas, with particular attention to norovirus, which is responsible for most viral gastroenteritis in France...

Fresh vegetables and their ready-to-eat (RTE) salads have become increasingly recognized as potential vehicles for foodborne diseases. The EU Reg. 1441/2007 establishes microbiological criteria for bacterial pathogens for products placed on the market during their shelf-life (i.e. Salmonella spp., Listeria monocytogenes) for pre-cut fruits and vegetables (RTE) whilst it does not address the problem of contamination by enteric viruses. In this study we investigated the contamination by hepatitis A virus (HAV), hepatitis E virus (HEV) and norovirus (NoV) in 911 ready-to-eat vegetable samples taken from products at retail in Apulia and in Lombardia...

Hepatitis E virus (HEV) is responsible for more than 50% of acute viral hepatitis cases in endemic countries. Approximately 2 billion individuals live in hepatitis E-endemic areas and, therefore, are at risk of infection. According to World Health Organization, HEV causes about 20.1 million infections and 70 000 deaths every year. In developing countries with poor sanitation, this disease is transmitted through contaminated water and is associated with large outbreaks, affecting hundreds or thousands of people...

We report a rare case of acute liver failure from acute hepatitis E virus (HEV) in a non-pregnant woman without comorbidities who survived after liver transplantation. The source was likely consumption of partially cooked pig liver. HEV genotype 3 is the second most common genotype causing acute hepatitis E in developed countries. Fulminant hepatitis E rarely occurs without a risk factor, as in our patient. Vigilant monitoring for chronic hepatitis E in post-transplant immunocompromised patients is needed.

OBJECTIVES: Hepatitis E virus (HEV) genotype 3 is endemic in Europe and an underdiagnosed and emerging (public) health issue. In recent years commercial enzyme immunoassays (EIAs) that detect antibodies to HEV more adequately, became available. We investigated the added value of this HEV serology in the diagnostic work flow to detect viral causes of recent hepatitis. METHODS: During a two year period (May 2013 - May 2015), HEV serology was added to the hepatitis work flow, consisting of serological detection of hepatitis A-B-C virus (HAV, HBV, HCV), Epstein-Barr Virus (EBV) and Cytomegalovirus (CMV)...

Hepatitis E virus (HEV) has been detected in rabbits, a recently identified natural reservoir. In this study, anti-HEV antibodies and viral RNA were detected in rabbits sourced from a specific-pathogen-free (SPF) rabbit vendor in Shaanxi Province, China. BLAST results of partial HEV ORF2 genes cloned here indicated that two viral strains circulated in the rabbits. Sequence determination of the complete genome (7302bp) of one strain and a partial ORF1 gene (1537bp) of the other strain showed that they shared 90% identity with one another and 78%-94% identity with other known rabbit HEVs...

Hepatitis E virus still poses a great threat to public health worldwide. To date, Hecolin® is the only licensed HEV vaccine in China. Total anti-HEV antibody has been used to reflect vaccine induced immune response in clinical trials for the lack of robust HEV neutralizing antibody detection methods. In this study, we applied a broad neutralizing mouse monoclonal antibody 8G12 to develop a competitive ELSIA assay and quantified 8G12 competitive antibody (8G12-like antibody) in serum samples. The presence of 8G12-like antibody was detected both from participants from HEV vaccine clinical trial and mice immunized with HEV vaccine...

A plethora of viruses can be transmitted by the food- and waterborne route. However, their recognition is challenging because of the variety of viruses, heterogeneity of symptoms, the lack of awareness of clinicians, and limited surveillance efforts. Classical food- and waterborne viral disease outbreaks are mainly caused by caliciviruses, but the source of the virus is often not known and the foodborne mode of transmission is difficult to discriminate from human-to-human transmission. Atypical food- and waterborne viral disease can be caused by viruses such as hepatitis A and hepatitis E...

INTRODUCTION: The incidence of hepatitis E (HEV) genotype 3 is rising in developed countries. HEV infections are usually self-limiting, but can become chronic in immunocompromised patients. This might lead to rapid fibrosis development even resulting in cirrhosis. Chronic HEV is mainly described in patients after solid-organ or hematological transplantations. We present the first case of HEV infection in a patient with tuberous sclerosis complex (TSC) treated with everolimus, a mammalian target of rapamycin (mTOR) inhibitor...

The neuralgic amyotrophy may be of difficult diagnosis, due to phenotypic variability, with different initial presentations (upper plexus multiple mononeuropathy, lumbosacral involvement, distal reached, phrenic involvement). To date, there is little guidance on these patients' therapeutic management, especially those for which neuralgic amyotrophy is triggered by hepatitis E virus (HEV-NA). The study aims to identify specific features that characterize patients bearing the neuralgic amyotrophy triggered by HEV...

Our objective was to determine the incidence and clinical manifestations of acute hepatitis E virus (HEV) in HIV-infected patients. A prospective longitudinal study including HIV-infected HEV-seronegative patients was conducted; HEV seroconversion (to IgG and/or IgM) was the main outcome variable. All patients were tested for HEV antibodies every 3-6 months. For patients who developed HEV seroconversion, a data collection protocol was followed to identify associated clinical manifestations and analytical alterations...
