| analysis of helicase domain mutations in the hepatitis e virus derived from patients with fulminant hepatic failure: effects on enzymatic activities and virus replication. | fulminant hepatic failure (fhf) is the severe form of hepatitis e virus infection. virus sequence analyses from severe cases have shown presence of unique and highly conserved mutations in the helicase domain of genotype 1, 3 and 4 viruses. we evaluated role of two amino acid replacements (l1110f) and (v1120i); found to be frequent in genotype 1 fhf-e viruses from india. three mutant helicase proteins (two with single point mutations and one with dual mutations) were expressed in escherichia col ... | 2014 | 24630891 |
| development of enzyme-linked immunosorbent assays using 2 truncated orf2 proteins for detection of igg antibodies against hepatitis e virus. | without appropriate culture systems for hepatitis e virus (hev), sufficient natural viral proteins are difficult to generate for use in serological tests. therefore, it is important to produce large amounts of hev recombinant proteins in an economical way. the present study developed elisas using 2 truncated forms of the hev open reading frame (orf) 2 protein in order to detect anti-hev igg in serum samples. | 2014 | 24624347 |
| development of a vectored vaccine against hepatitis e virus. | hepatitis e virus is a non-enveloped ssrna virus [1] that causes human acute hepatitis through primarily fecal and oral transmission [2]. currently, no commercial hepatitis e (hev) vaccine is available. in the absence of an appropriate cell culture system for hev propagation, hev pseudocapsids (orf2 protein) have been produced either in escherichia coli or in insect cells and they have been shown to protect monkeys against virus challenge and to be effective in the prevention of natural hev infe ... | 2014 | 24583005 |
| a dual vaccine candidate against norovirus and hepatitis e virus. | norovirus (nov) and hepatitis e virus (hev) are both enterically-transmitted viruses causing gastroenteritis and hepatitis, respectively, in humans. while a vaccine against hevs recently became available in china, there is no prophylactic or therapeutic approach against novs. both nov and hev have surface protrusions formed by dimers of the protruding (p) domains of the viral capsids, which is responsible for virus-host interactions and eliciting viral neutralizing antibody. we developed in this ... | 2014 | 24291540 |
| [prokaryotic expression and characterization of truncated mutant capsid protein of genotype iv hepatitis e virus]. | a truncated mutant of the open reading frame 2 (orf2, aa384-606) was amplified from cdna of genotype iv hepatitis e virus (hev) by polymerase chain reaction (pcr), subcloned to expression plasmid pto-t7, and expressed in escherichia coli. sds-page and western blotting were used to detect and identify the recombinant protein, namely rp24. after washing of inclusion bodies, dissolving in denaturing agents, refoldeding by dialysis, ion exchange chromatography and gel chromatography, dynamic light s ... | 2014 | 25007574 |
| detection and characterization of potentially zoonotic viruses in faeces of pigs at slaughter in germany. | pigs can harbour a variety of viruses in their gastrointestinal tract. some of them are closely related to human viruses and are therefore suspected to have a zoonotic potential. only little is known about the presence of those viruses in pigs at slaughter. however, by contamination of meat with zoonotic viruses during the slaughtering process, food-borne transmission to humans may be possible. here we analyzed 120 faecal samples of pigs at slaughter from 3 different geographical regions of germ ... | 2014 | 24247020 |
| clinical & immunological profile of newly diagnosed patients with youth onset diabetes mellitus. | there has been a rise in the incidence of diabetes mellitus in the younger population of india. there are limited data available on the immunological profile of youth onset diabetes mellitus (dm) especially in type 2. therefore, this study was undertaken to evaluate the clinical and immunological profile of youth onset dm in north india. | 2014 | 25366202 |
| acute viral hepatitis - should the current screening strategy be modified? | the epidemiology of viral hepatitis has changed. since the introduction of safe and effective vaccines for hepatitis a and b in 1980s, the incidence of acute infections caused by these viruses has been declining in the uk. at the same time, hepatitis e virus (hev) has been recognised as an increasingly important cause of acute hepatitis, but testing is not widely available. | 2014 | 24472576 |
| serological cross reactivity to cmv and ebv causes problems in the diagnosis of acute hepatitis e virus infection. | hepatitis e virus (hev) infection is an important public health concern as a major cause of enterically-transmitted hepatitis worldwide. the detectable window of viraemia is narrow, and hev igm and igg rise simultaneously in acute infection. furthermore, previous investigators have shown hev igm false positive reactions occur against ebv, cmv and potentially hepatitis a. a retrospective analysis of hev serology testing was performed at a london tertiary referral hospital over a 3-year period. a ... | 2014 | 24402843 |
| detection of pathogenic viruses in sewage provided early warnings of hepatitis a virus and norovirus outbreaks. | most persons infected with enterically transmitted viruses shed large amounts of virus in feces for days or weeks, both before and after onset of symptoms. therefore, viruses causing gastroenteritis may be detected in wastewater, even if only a few persons are infected. in this study, the presence of eight pathogenic viruses (norovirus, astrovirus, rotavirus, adenovirus, aichi virus, parechovirus, hepatitis a virus [hav], and hepatitis e virus) was investigated in sewage to explore whether their ... | 2014 | 25172863 |
| evaluation of viral inactivation of pseudorabies virus, encephalomyocarditis virus, bovine viral diarrhea virus and porcine parvovirus in pancreatin of porcine origin. | pancreatin is a substance containing enzymes, principally amylase, lipase, and protease. it is obtained from bovine or porcine pancreas and used in the treatment of pancreatic endocrine insufficiency in humans. regulations and safety concerns mandate viral clearance (virus removal or inactivation) in biopharmaceuticals such as pancreatin. a virus validation study was performed to evaluate virus clearance achieved in the final step of drying under vacuum by testing a panel of four animal viruses: ... | 2014 | 25110118 |
| dengue and hepatitis e virus infection in pregnant women in eastern sudan, a challenge for diagnosis in an endemic area. | dengue fever and hepatitis e virus infection are both a public health problem in developing countries due to poor sanitation. infection with viral hepatitis and dengue fever can present with similar clinical such and fever, headache and abortion. this study was conducted in port-sudan city in the eastern part of the country. elisa and real time pcr tests were used to detect the infection. a total number of 39 pregnant women with a mean age 26 ±7.8 were included in the study. all of them had feve ... | 2014 | 25995787 |
| quantitative proteomics identifies host factors modulated during acute hepatitis e virus infection in the swine model. | hepatitis e virus (hev) causes acute enterically transmitted hepatitis. in industrialized countries, it is a zoonotic disease, with swine being the major reservoir of human hev contamination. the occurrence and severity of the disease are variable, with clinical symptoms ranging from asymptomatic to self-limiting acute hepatitis, chronic infection, or fulminant hepatitis. in the absence of a robust cell culture system or small-animal models, the hev life cycle and pathological process remain unc ... | 2014 | 25320303 |
| hepatitis a and e seroprevalence and associated risk factors: a community-based cross-sectional survey in rural amazonia. | hepatitis a virus (hav) and hepatitis e virus (hev) are both transmitted by the faecal-oral route, and represent common causes of acute hepatitis in developing countries. the endemicity of hav infection has shifted from high to moderate in brazil. human cases of hev infection seem to be rare, although the virus has been detected in swine livestock and effluents of slaughterhouses. this study was to determine the epidemiology of hepatitis a and e in one of the largest agricultural settlements in ... | 2014 | 25149658 |
| changes in the cellular proteins of a549 infected with hepatitis e virus by proteomics analysis. | our understanding of hepatitis e virus (hev) has changed enormously over the past 30 years, from a waterborne infection causing outbreaks of acute hepatitis in developing countries to an infection of global distribution causing a range of hepatic and extra-hepatic illness. however, the key proteins playing important parts in the virus infection were still unknown. understanding the changes of cellular proteins in these cells exposed to hev is helpful for elucidating molecular mechanisms associat ... | 2014 | 25175408 |
| hepatitis e vaccine to prevent morbidity and mortality during epidemics. | recurrent, large, waterborne epidemics of hepatitis e virus (hev) occur regularly after monsoon rains contaminate water supplies in asia or during humanitarian crises in africa. these epidemics commonly affect thousands of persons, and it has a high mortality in pregnant women who become infected. although a subunit hev vaccine has been developed by chinese investigators and was found to be highly effective and safe in a large clinical trial, this vaccine is only available in china. until it is ... | 2014 | 25734166 |

| the relationship between socioeconomic indices and potentially zoonotic pathogens carried by wild norway rats: a survey in rhône, france (2010-2012). | leptospira interrogans, hantaviruses (particularly seoul virus), hepatitis e virus (hev), and toxoplasma gondii are rat-associated zoonoses that are responsible for human morbidity and mortality worldwide. this study aimed to describe the infection patterns of these four pathogens in wild rats (rattus norvegicus) across socioeconomic levels in neighbourhoods in lyon, france. the infection or exposure status was determined using polymerase chain reaction or serology for 178 wild rats captured in ... | 2014 | 24838220 |
| ribavirin inhibits in vitro hepatitis e virus replication through depletion of cellular gtp pools and is moderately synergistic with alpha interferon. | hepatitis e virus (hev) is a common cause of acute hepatitis that results in high mortality in pregnant women and may establish chronic infections in immunocompromised patients. we demonstrate for the first time that alpha interferon (ifn-α) and ribavirin inhibit in vitro hev replication in both a subgenomic replicon and an infectious culture system based on a genotype 3 strain. ifn-α showed a moderate but significant synergism with ribavirin. these findings corroborate the reported clinical eff ... | 2014 | 24145541 |
| hepatitis e infection in liver transplant recipients. | hepatitis e virus (hev) infection (genotype 3) has been described in developed countries as a cause of chronic hepatitis in recipients of solid organ transplantation (sot), with the first cases reported in 2008. immunosuppression seems to play a major role in the pathogenesis of chronic infections. the current gold standard for the diagnosis of hev infection is the detection of hev rna in serum, stools, or both. in liver transplant recipients, hev infection is considered an uncommon disease; how ... | 2014 | 24123928 |
| prevalence of hepatitis e virus antibodies in children in germany. | since asymptomatic hepatitis e virus (hev) infections particularly affect children, there is a need for studies to determine the hev seroprevalence among infants, children and adolescents. | 2014 | 24168981 |
| emergence of autochthonous infections with hepatitis e virus of genotype 4 in europe. | in europe, autochthonous hepatitis e is caused by genotype 3 hepatitis e virus (hev) in almost all cases. a total of 15 infections with genotype 4 hev were diagnosed in france from may 2009 to april 2012, and all but one of the hev-4 strains implicated in these infections were genetically related and highly similar to hev-4 sequences isolated from swine in belgium. in addition, 5 autochthonous hev-4 infections have been described in the region of lazio, italy, during march and april 2011, and th ... | 2014 | 24157452 |
| patients infected with hiv are at high-risk for hepatitis e virus infection in spain. | hepatitis e virus is responsible for sporadic cases of acute, self-limited viral hepatitis not only in endemic but also in industrialized countries. in addition, some reports confirm that it can cause chronic infection and even cirrhosis in immunosuppressed and also in patients infected with hiv. there are few data about prevalence and incidence of hev chronic infection in hiv-hev coinfected individuals in spain. the aim of this study is to investigate the prevalence of anti-hev igg in a represe ... | 2014 | 24136591 |
| indigenous hepatitis e in england and wales from 2003 to 2012: evidence of an emerging novel phylotype of viruses. | enhanced surveillance and molecular characterisation studies of hepatitis e virus (hev) in england and wales have been undertaken since 2003. the dynamics of hepatitis e have changed recently with an increase in the number of indigenous cases and an observed viral shift. | 2014 | 24273173 |
| evaluation of hepatitis e virus infection between different production systems of pigs in brazil. | the objectives of this study were to (1) investigate the occurrence of hepatitis e virus (hev) in pigs from large-scale and family-scale farms, (2) genetically characterize the strains isolated, and (3) study the pathogenesis of swine hev infection via immunohistochemistry. a total of 50 pigs from 10 farms in mato grosso state, brazil were divided according to type of production system into either large-scale farms (n = 5) or family-scale farms (n = 5). samples of liver, gallbladder, small and l ... | 2014 | 24272392 |
| colorimetric detection of hepatitis e virus based on reverse transcription loop mediated isothermal amplification (rt-lamp) assay. | hepatitis e virus (hev) infection is a common communicable disease in the third world countries. the early diagnosis of hev is important for the prognosis and prevention of the spread of the disease. conventional methods for hev detection need expensive equipment and cannot meet the needs of point of care (poc) use. in the present study, a gold nanoparticle (aunp) based rt-lamp assay was developed for colorimetric detection of hev. as low as 10(1) copies of hev rna were detected visually. with r ... | 2014 | 24269797 |
| peek-a-boo: membrane hijacking and the pathogenesis of viral hepatitis. | historically, animal viruses have been classified on the basis of the presence or absence of an envelope - an external lipid bilayer membrane typically carrying one or more viral glycoproteins. however, growing evidence indicates that some 'non-enveloped' viruses circulate in the blood of infected individuals enveloped in host-derived membranes that provide protection from neutralizing antibodies. in this opinion article, we discuss this novel strategy for virus survival and consider how it cont ... | 2014 | 24268716 |
| development of a novel immunoperoxidase monolayer assay for detection of swine hepatitis e virus antibodies based on stable cell lines expressing the orf3 protein. | hepatitis e virus (hev) strains are classified into 4 genotypes by nucleotide sequencing. genotypes 3 and 4 infect humans and animals via hev-contaminated food or water. hev rna was detected by pcr and antibodies were detected by elisa. since human studies showed that hev igg antibodies in sera can persist for extended periods, diagnosis of hev infection in swine or humans is mainly based on serological detection using commercial elisa kits. however, there is no supplemental method to verify eli ... | 2014 | 24334082 |
| mutagenesis of hepatitis e virus helicase motifs: effects on enzyme activity. | hepatitis e virus (hev), the causative agent of hepatitis e, is a non-enveloped rna virus. the open reading frame 1 encoded non-structural polyprotein has putative domains for methyltransferase, cysteine protease, helicase and rna-dependent rna polymerase, however processing of this polyprotein is still uncertain. hev helicase belongs to superfamily 1 and has all seven conserved motifs typical of the family. ntpase and rna duplex unwinding activities of hev helicase domain were recently demonstr ... | 2014 | 24333153 |
| hepatitis e virus open reading frame 3 protein interacts with porcine liver-specific plasminogen and α2-antiplasmin. | hepatitis e virus (hev) is a hepatotropic virus that causes acute and, occasionally, chronic viral hepatitis. at least four recognized genotypes of mammalian hev have been identified. genotypes 3 and 4 are zoonotic in humans and pigs are the major host. the 7.2 kb genome of hev contains three open reading frames: orf1, orf2, and orf3. orf1 encodes a nonstructural protein and the orf2 protein is the main capsid protein but the precise functions of orf3 protein remain obscure. to explore the role ... | 2014 | 24249579 |
| duration of viraemia in chinese acute sporadic hepatitis e. | acute sporadic hepatitis e (ashe) cases induced by hepatitis e virus genotype 4 (hev-4) are increasing in china. our study aimed to estimate the duration of hev-4 viraemia in chinese ashe. a total of 619 serum specimens from 499 ashe patients were examined for the presence of hev rna. the association between viraemia detection and serum sampling time was compared between subtypes. the cumulative probability of hev viraemia detection was determined using kaplan-meier survival analysis, and the vi ... | 2014 | 24241947 |
| marked genomic heterogeneity of rat hepatitis e virus strains in indonesia demonstrated on a full-length genome analysis. | rat hepatitis e virus (hev) strains have recently been isolated in several areas of germany, vietnam, the united states, indonesia and china. however, genetic information regarding these rat hev strains is limited. a total of 369 wild rats (rattus rattus) captured in central java (solo) and on lombok island, indonesia were tested for the presence of rat hev-specific antibodies and rna. overall, 137 rats (37.1%) tested positive for rat anti-hev antibodies, while 97 (26.3%) had rat hev rna detecta ... | 2014 | 24231359 |
| the membrane on the surface of hepatitis e virus particles is derived from the intracellular membrane and contains trans-golgi network protein 2. | our previous studies demonstrated that hepatitis e virus (hev) requires the multivesicular body (mvb) pathway to release virus particles, suggesting that hev utilizes the cellular escrt machinery in the cytoplasm, not at the cell surface, to be released from infected cells. in this study, we generated a murine monoclonal antibody (mab) against the membrane-associated hev particles to examine whether the membrane is derived from intracellular vesicles or the cell surface. an established mab, ta17 ... | 2014 | 24221250 |
| role of nitric oxide synthase genes in hepatitis e virus infection. | hepatitis e virus (hev) is the most common cause of endemic and epidemic acute hepatitis. a correlation between inos, enos polymorphisms, levels and severity of disease has been reported, and here, we examined the role of inos and enos gene polymorphisms and their levels in hev-related acute viral hepatitis and acute liver failure. hepatitis e virus-related cases of acute hepatitis (294 patients) and liver failure (82 patients) and age- and sex-matched healthy controls (331 subjects) were includ ... | 2014 | 24215170 |

| course and treatment of chronic hepatitis e virus infection in lung transplant recipients. | persistent hepatitis e virus (hev) infections have been described in various transplant cohorts. however, the frequency and the course of hev infection in lung transplant recipients (lu-tr) are not well defined. | 2014 | 24438577 |
| hepatitis e virus reinfections in solid-organ-transplant recipients can evolve into chronic infections. | hepatitis e virus (hev) infections are a major cause of acute hepatitis in developing and industrialized countries. little is known about anti-hev immunity in solid-organ recipients. | 2014 | 24436450 |
| hepatitis e: an emerging disease. | currently, the infection with the hepatitis e virus represents the most frequent cause for acute hepatitis and jaundice in the world. according to who estimations, around two billion people, representing one third of the world's population, live in endemic areas for hev and, therefore, are at risk of infection. in developed countries, the circulation of the virus in both human and animal (swine, boar, deer) sewage has been confirmed; however, the incidence rate is low compared to that of develop ... | 2014 | 24434240 |
| comparison of real-time reverse transcriptase pcr assays for detection of swine hepatitis e virus in fecal samples. | hepatitis e virus (hev) is a major cause of acute viral hepatitis in people in many developing countries and is also endemic in many industrialized countries. mammalian hev (mhev) isolates can be divided into at least four recognized major genotypes. several nucleic acid amplification techniques have been developed for mhev detection, with great differences in sensitivity. the aim of this study was to compare the performances of two singleplex real-time reverse transcriptase (rt) pcr assays for ... | 2014 | 24430450 |
| hepatitis e virus infections in humans and animals. | hepatitis e has traditionally been considered an endemic disease of developing countries. it generally spreads through contaminated water. however, seroprevalence studies have shown that hepatitis e virus (hev) infections are not uncommon in industrialized countries. in addition, the number of autochthonous hepatitis e cases in these countries is increasing. most hev infections in developed countries can be traced to the ingestion of contaminated raw or undercooked pork meat or sausages. several ... | 2014 | 24427760 |
| method for hev detection in raw pig liver products and its implementation for naturally contaminated food. | it is now recognized that hepatitis e virus (hev) infection is not confined to developing countries. hev infection is a growing public health concern in industrialized countries where the disease is mainly autochthonous, caused by hev genotypes 3 and 4 and is today considered to be zoonotic. hev causes acute hepatitis in humans, predominantly through contamination of food and water. due to the low concentrations found in food and water samples, an efficient and rapid virus concentration method i ... | 2014 | 24553051 |
| serum from patients with hepatitis e virus-related acute liver failure induces human liver cell apoptosis. | the pathogenesis of acute liver failure has not been fully elucidated. the present study investigated the effects of the serum from patients with hepatitis e virus (hev)-related acute liver failure on human liver cell survival and apoptosis, and evaluated the protective effects of anti-lipopolysaccharide(lps) antibody recognizing core polysaccharide against acute liver failure serum-induced apoptosis. serum was collected from patients with hev-related acute liver failure. the levels of endotoxin ... | 2014 | 24348810 |
| novel hepatitis e like virus found in swedish moose. | a novel virus was detected in a sample collected from a swedish moose (alces alces). the virus was suggested as a member of the hepeviridae family, although it was found to be highly divergent from the known four genotypes (gt1-4) of hepatitis e virus (hev). moose are regularly hunted for consumption in the whole of scandinavia. thus, the finding of this virus may be important from several aspects: (a) as a new diverged hev in a new animal species, and (b) potential unexplored hev transmission p ... | 2014 | 24296469 |
| risk factors associated with the presence of hepatitis e virus in livers and seroprevalence in slaughter-age pigs: a retrospective study of 90 swine farms in france. | the frequency of sporadic cases of hepatitis e in humans in developed countries has increased in recent years. the consumption of raw or undercooked pig liver-based products has been identified as an important source of human infection. the question of possible massive human exposure to this zoonotic agent has been raised by the high prevalence of hepatitis e virus (hev) in swine herds. however, little is known about the epidemiology of hev on pig farms. a retrospective study, based on a previou ... | 2014 | 24284046 |
| endemic hepatitis e in the czech republic. | an increasing incidence of endemic hepatitis e (he) has been reported in developed countries. thus, an evaluation of the clinical characteristics of the disease and the utility of the current diagnostic methods is warranted. | 2014 | 24280093 |
| fetal and neonatal health consequences of vertically transmitted hepatitis e virus infection. | hepatitis e virus (hev) infections lead to tens of thousands of deaths annually, mostly in developing countries. hepatitis e poses a significant threat to the health of expectant mothers, a well-noted epidemiologic feature of the disease, but the contribution of vertically transmitted hev infection to fetal and neonatal morbidity and mortality has received limited attention. evidence assembled to date suggests that mother-to-child hev transmission may be frequent and deleterious to the fetus and ... | 2014 | 24420778 |
