Abstract
Hepatitis E virus (HEV) has traditionally been associated with an acute, self-limiting hepatitis and is not known to have any chronic sequelae. HEV genotypes 1 and 2, which are human pathogens, have been associated with this self-limiting presentation, in both sporadic and epidemic settings. HEV genotype 3, which is zoonotically transmitted, is increasingly being reported as a cause of chronic infection in immunocompromised patients. These include patients with solid organ transplants, patients receiving chemotherapy for haematologic malignancies and patients infected with HIV. Chronic infection is associated with rapidly progressing liver disease and extrahepatic manifestations including neurologic disorders. We review the clinical manifestations of chronic HEV infection and discuss factors determining persistence and chronicity of HEV.

Abstract
Hepatitis (HEV) is widely distributed in pigs and is transmitted with increasing numbers to humans by contact with pigs, contaminated food and blood transfusion. The virus is mostly apathogenic in pigs but may enhance the pathogenicity of other pig viruses. In humans, infection can lead to acute and chronic hepatitis and extrahepatic manifestations. In order to stop the emerging infection, effective counter-measures are required. First of all, transmission by blood products can be prevented by screening all blood donations. Meat and sausages should be appropriately cooked. Elimination of the virus from the entire pork production can be achieved by sensitive testing and elimination programs including early weaning, colostrum deprivation, Caesarean delivery, embryo transfer, treatment with antivirals, protection from de novo infection, and possibly vaccination. In addition, contaminated water, shellfish, vegetables, and fruits by HEV-contaminated manure should be avoided. A special situation is given in xenotransplantation using pig cells, tissues or organs in order to alleviate the lack of human transplants. The elimination of HEV from pigs, other animals and humans is consistent with the One Health concept, preventing subclinical infections in the animals as well as preventing transmission to humans and disease.

Abstract
Hepatitis viruses are major threats to human health. During the last decade, highly diverse viruses related to human hepatitis viruses were found in animals other than primates. Herein, we describe both surprising conservation and striking differences of the unique biological properties and infection patterns of human hepatitis viruses and their animal homologues, including transmission routes, liver tropism, oncogenesis, chronicity, pathogenesis and envelopment. We discuss the potential for translation of newly discovered hepatitis viruses into preclinical animal models for drug testing, studies on pathogenesis and vaccine development. Finally, we re-evaluate the evolutionary origins of human hepatitis viruses and discuss the past and present zoonotic potential of their animal homologues.

Abstract
Objectives: Hepatitis E virus (HEV) infection is a pandemic with regional outbreaks, including in industrialized countries. HEV infection is usually self-limiting but can progress to chronic hepatitis E in transplant recipients and HIV-infected patients. Whether other immunocompromised hosts, including rheumatology and internal medicine patients, are at risk of developing chronic HEV infection is unclear. Methods: We conducted a retrospective European multicenter cohort study involving 21 rheumatology and internal medicine patients with HEV infection between April 2014 and April 2016. The underlying diseases included rheumatoid arthritis (n = 5), psoriatic arthritis (n = 4), other variants of chronic arthritis (n = 4), primary immunodeficiency (n = 3), systemic granulomatosis (n = 2), lupus erythematosus (n = 1), Erdheim–Chester disease (n = 1), and retroperitoneal fibrosis (n = 1). Results: HEV infection lasting longer than 3 months was observed in seven (33%) patients, including two (40%) patients with rheumatoid arthritis, three (100%) patients with primary immunodeficiency, one (100%) patient with retroperitoneal fibrosis and one (100%) patient with systemic granulomatosis. Patients with HEV infection lasting longer than 3 months were treated with methotrexate without corticosteroids (n = 2), mycophenolate mofetil/prednisone (n = 1), and sirolimus/prednisone (n = 1). Overall, 8/21 (38%) and 11/21 (52%) patients cleared HEV with and without ribavirin treatment, respectively. One patient experienced an HEV relapse after initially successful ribavirin therapy. One patient (5%) was lost to follow-up, and no patients died from hepatic complications. Conclusion: Rheumatology and internal medicine patients, including patients treated with methotrexate without corticosteroids, are at risk of developing chronic HEV infection. Rheumatology and internal medicine patients with abnormal liver tests should be screened for HEV infection.

Abstract
OBJECTIVES Hepatitis E virus genotype 3 (HEV3) is responsible for acute and chronic liver disease in solid organ transplant (SOT) recipients. HEV was recently found in the urine of some acutely and chronically genotype 4-infected patients. METHODS We examined the urinary excretion of HEV3 by 24 consecutive SOT recipients at the acute phase of HEV hepatitis and characterized the excreted virus. RESULTS Urinary HEV RNA was detected in 12 (50%) of the 24 transplanted patients diagnosed with HEV hepatitis. Urinary HEV antigen (Ag) was detected in all but one of the patients (96%). The density of RNA-containing HEV particles in urine was low (1.11-1.12 g/cm3), corresponding to lipid-associated virions. The urinary HEV RNA/Ag detected was not associated with impaired kidney function or de novo proteinuria. Finally, there was more HEV Ag in the serum at the acute phase of HEV infection in SOT recipients whose infection became chronic. CONCLUSIONS HEV3 excreted via the urine of SOT recipients at the acute phase of HEV hepatitis has a lipid envelope. Renal function was not impaired. While urinary HEV Ag was a sensitive indicator of HEV infection, only acute phase serum HEV Ag indicated the development of a chronic infection.

Abstract
Hepatitis E virus (HEV) is the causative agent of hepatitis E in humans and is the leading cause of enterically-transmitted viral hepatitis worldwide. Increasing numbers of HEV infections, together with no available specific anti-HEV treatment, contributes to the pathogen's major health burden. A robust cell culture system is required for virologic studies and the development of new antiviral drugs. Unfortunately, like other hepatitis viruses, HEV is difficult to propagate in conventional cell lines. Many different cell culture systems have been tested using various HEV strains, but viral replication usually progresses very slowly, and infection with low virion counts results in non-productive HEV replication. However, recent progress involving generation of cDNA clones and passaging primary patient isolates in distinct cell lines has improved in vitro HEV propagation. This review describes various approaches to cultivate HEV in cellular and animal models and how these systems are used to study HEV infections and evaluate anti-HEV drug candidates.

Abstract
Half a century has passed since the first orthotopic heart transplant took place. Surgical innovations allowed for heart, lung, and heart-lung transplantation to save lives of patients with incurable chronic cardiopulmonary conditions. The complexity of the surgical interventions, chronic host health conditions, and antirejection immunosuppressive medications makes infectious complications common. Infections have remained one of the main barriers for successful transplantation and a source of significant morbidity and mortality. Recognition of infections and its management in this setting require outstanding clinical skills since transplant recipients may not exhibit classic signs or symptoms of disease, and laboratory work has some pitfalls. The prevention, identification, and management of infectious diseases complications in this population are a priority to undertake to improve the medical outcomes of transplantation. Herein, we reviewed the historical aspects, epidemiology, and prophylaxis of infections in heart, lung, and heart-lung transplantation. We also discuss the most prevalent organisms affecting the host and the organ systems involved.

Abstract
Liver transplantation has become an important treatment modality for patients with end-stage liver disease/cirrhosis, acute liver failure, and hepatocellular carcinoma. Although surgical techniques and immunosuppressive regimens for liver transplantation have improved significantly over the past 20 years, infectious complications continue to contribute to the morbidity and mortality in this patient population. The use of standardized screening protocols for both donors and recipients, coupled with targeted prophylaxis against specific pathogens, has helped to mitigate the risk of infection in liver transplant recipients. Patients with chronic liver disease and cirrhosis have immunological deficits that place them at increased risk for infection while awaiting liver transplantation. The patient undergoing liver transplantation is prone to develop healthcare-acquired infections due to multidrug-resistant organisms that could potentially affect patient outcomes after transplantation. The complex nature of liver transplant surgery that involves multiple vascular and hepatobiliary anastomoses further increases the risk of infection after liver transplantation. During the early post-transplantation period, healthcare-acquired bacterial and fungal infections are the most common types of infection encountered in liver transplant recipients. The period of maximal immunosuppression that occurs at 1–6 months after transplantation can be complicated by opportunistic infections due to both primary infection and reactivation of latent infection. Severe community-acquired infections can complicate the course of liver transplantation beyond 12 months after transplant surgery. This chapter provides an overview of liver transplantation including indications, donor-recipient selection criteria, surgical procedures, and immunosuppressive therapies. A focus on infections in patients with chronic liver disease/cirrhosis and an overview of the specific infectious complications in liver transplant recipients are presented.

Abstract
Hepatitis E virus (HEV) is the most common cause of viral hepatitis in the world. It is estimated that millions of people are infected every year, resulting in tens of thousands of deaths. However, these estimates do not include industrialized regions and are based on studies which employ assays now known to have inferior sensitivity. As such, this is likely to represent a massive underestimate of the true global burden of disease. In the developing world, HEV causes large outbreaks and presents a significant public-health problem. Until recently HEV was thought to be uncommon in industrialized countries, and of little relevance to clinicians in these settings. We now know that this is incorrect, and that HEV is actually very common in developed regions. HEV has proved difficult to study in vitro, with reliable models only recently becoming available. Our understanding of the lifecycle of HEV is therefore incomplete. Routes of transmission vary by genotype and location: endemic regions experience large waterborne epidemics, while sporadic cases in industrialized regions are zoonotic infections likely spread via the food chain. Both acute and chronic infection has been observed, and a wide range of extrahepatic manifestations have been reported. This includes neurological, haematological and renal conditions. As the complete clinical phenotype of HEV infection is yet to be characterized, a large proportion of cases go unrecognized or misdiagnosed. In many cases HEV infection does not feature in the differential diagnosis due to a lack of knowledge and awareness of the disease amongst clinicians. In combination, these factors have contributed to an underestimation of the threat posed by HEV. Improvements are required in terms of recognition and diagnosis of HEV infection if we are to understand the natural history of the disease, improve management and reduce the burden of disease around the world.

Abstract
Infectious complications have been considered as a major cause of morbidity and mortality after kidney transplantation, especially in the Asian population. Therefore, prevention, early detection, and prompt treatment of such infections are crucial in kidney transplant recipients. Among all infectious complications, viruses are considered to be the most common agents because of their abundance, infectivity, and latency ability. Herpes simplex virus, varicella zoster virus, Epstein-Barr virus, cytomegalovirus, hepatitis B virus, BK polyomavirus, and adenovirus are well-known etiologic agents of viral infections in kidney transplant patients worldwide because of their wide range of distribution. As DNA viruses, they are able to reactivate after affected patients receive immunosuppressive agents. These DNA viruses can cause systemic diseases or allograft dysfunction, especially in the first six months after transplantation. Pretransplant evaluation and immunization as well as appropriate prophylaxis and preemptive approaches after transplant have been established in the guidelines and are used effectively to reduce the incidence of these viral infections. This review will describe the etiology, diagnosis, prevention, and treatment of viral infections that commonly affect kidney transplant recipients.

Abstract
BACKGROUND & AIMS An association between hepatitis E virus (HEV) infection and cryoglobulinemia has been suggested. The aims of this study were to assess the prevalence of cryoglobulinemia during HEV infection in solid-organ-transplant (SOT) recipients, to describe its outcomes under ribavirin therapy and to evaluate its effects on kidney function and histology. METHODS Between November 2005 and June 2016, 128 cases of HEV infection were diagnosed among SOT recipients followed in our institution. Cryoglobulinemia data obtained from 66 patients during acute-phase HEV and 51 patients during chronic-phase HEV were compared to a historical control group of 89 SOT recipients without HEV markers. Cryoglobulins were also monitored in a group of 43 patients treated by ribavirin. RESULTS The prevalence of cryoglobulinemia was increased in HEV-infected SOT patients during a chronic phase (52.9%) compared to HEV-infected SOT patients at acute phase (36.4%) (P = .1) and to HEV-negative SOT patients (23.6%) (P < .001). HEV infection was identified as an independent predictive factor for cryoglobulinemia (OR 2.3, CI 95%: 1.17-4.55, P = .02). After ribavirin therapy and HEV clearance, the prevalence of cryoglobulin was significantly decreased from 53.5% to 20.9% (P = .003). Kidney function was significantly worse and proteinuria tended to be higher in chronically HEV-infected patients with cryoglobulinemia compared to those without cryoglobulinemia. Membranoproliferative glomerulonephritis was diagnosed in 2 patients, of which 1 had detectable cryoglobulinemia. CONCLUSIONS In conclusion, a relationship between HEV and cryoglobulin formation seems to exist. However, the clinical impact of cryoglobulinemia in SOT patients infected with HEV has to be confirmed.

Autoantibodies to cytoplasmic rods and rings in patients with hepatitis C virus infection treated with direct-acting antivirals: The role of prior treatment with interferon plus ribavirin. GASTROENTEROLOGIA Y HEPATOLOGIA 2018; 42:82-89. [PMID: 30446175 DOI: 10.1016/j.gastrohep.2018.08.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2018] [Revised: 06/27/2018] [Accepted: 08/01/2018] [Indexed: 12/18/2022]
Abstract
INTRODUCTION The cytoplasmic rods-rings (RR) pattern is found in hepatitis C (HCV) patients treated with interferon-ribavirin when studied with ANA-IIF. Ribavirin aggregates/induces antigenic changes in IMPDH-2, an enzyme necessary for ribavirin action. PATIENTS AND METHOD Prospective search for anti-RR autoantibodies (HEp-2, INOVA) in patients treated with direct-acting antivirals (DAAs) from October 2015 to June 2017. HCV-negative patients from up to June 2016 acted as controls. Anti-RR was analyzed at baseline and, mainly, during treatment and follow-up. The Chi-square test, Student's t-test and a logistic regression analysis were performed. RESULTS Between October 2015 and June 2016, 1258 men and 2389 women who were HCV-negative and 137 men and 112 women who were HCV-positive patients were studied. Approximately 22.9% of HCV-negative and 13.2% of HCV-positive were ANA-IIF-positive (p<0.05). Three HCV-negative (0.08%) and 23 (9.2%) HCV-positive patients had anti-RR (p<0.001). A total of 122 patients received DAAs; 30 received DAA+RBV; 46 pre-treated with IFN-RBV received DAA; 31 pre-treated with IFN-RBV received DAA+RBV; 16 received IFNpeg-RBV; and 24 received IFN-RBV-DAA. None of the 122 DAA-treated patients showed anti-RR; anti-RR were identified in 14.8% of those treated with DAA-RBV; in 25.9% of those pre-treated with IFN-RBV receiving DAA; in 22.2% of IFN-RBV-pre-treated patients who received DAA+RBV; in 7.4% of those treated with IFNpeg-RBV and in 29.6% of those treated with IFNpeg-RBV-DAA. The multivariate analysis showed significant associations between anti-RR and "Exposure to IFN" and "Time of exposure to RBV". CONCLUSIONS Anti-RR autoantibodies were detected only in patients with current or past treatments with RBV, even in cases in which only DAAs were later administered.

Abstract
Following the introduction of robust serological and molecular tools, our understanding of the epidemiology of zoonotic hepatitis E virus (HEV) has improved considerably in recent years. Current thinking suggests that consumption of pork meat products is the key route of infection in humans, but it is certainly not the only one. Other routes of infection include environmental spread, contaminated water, and via the human blood supply. The epidemiology of HEV genotype (gt)3 and gt4 is complex, as there are several sources and routes of infection, and it is likely that these vary between and within countries and over time.

Abstract
Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are the major causes of chronic liver disease. HBV and HCV affect nearly 7% of the world's population. Extra-hepatic complications and particularly renal failure have different mechanisms and manifestations. The underlying mechanism, although differing for each disease, mainly involves the immune system and antibody deposits in the kidney, which can lead to tissue damage. Areas covered: We do not cover in this review hepatorenal syndrome. We report on the renal complications of viral hepatitis (HBV, HCV, hepatitis E), autoimmune hepatitis, cirrhosis, and Wilson's disease. The most frequent renal disorders are those related to HBV, and HCV due to their high prevalence worldwide. Expert commentary: Thanks to generalization of vaccination against HBV, prevalence of HBV-related liver diseases will decrease, and thereby its associated renal involvement such as polyarteritis nodosa (an exceptional condition), and glomerulonephritis such as membranous nephropathy. Thanks to direct acting antiviral agents HCV infection will be cured within the next decade. However, HCV-related cryoglobulinemia with or without renal involvement might evolve on its own after the patient has eliminated HCV, necessitating then rituximab therapy. Conversely, orofecal-transmitted hepatitis viruses such as hepatitis A and hepatitis E are still very prevalent in developing countries; however, they are rarely associated with renal manifestations.

Abstract
Hepatitis E virus (HEV) can cause chronic infections in immunosuppressed patients with adverse clinical outcomes. Intervention strategies are limited with ribavirin (RBV) being the only main therapeutic option as off-label drug. Recent reports on RBV monotherapy failures show a coherence with the presence of certain single nucleotide variants (SNVs) and in-frame insertions in the hypervariable region of open reading frame 1 in the HEV genome. Importantly, some of the alterations were present in the viral population as minor variant before RBV administration. Individualized infection medicine by early detection of emerging viral variants in patients could improve treatment outcome and prognosis.

Abstract
No commercial HEV RNA assay is validated for use in faecal samples. Monitoring HEV faecal excretion is recommended for managing chronic HEV infection in solid-organ transplant recipients. We evaluated the Altona assay by testing patients on ribavirin therapy.
Background Detecting hepatitis E virus (HEV) RNA in faeces is useful for diagnosing and monitoring HEV infections, particularly in immunocompromised patients requiring ribavirin therapy. Objectives This study evaluated the performance of the Altona RealStar HEV RNA kit for detecting and quantifying HEV in faeces. Study design RNA was extracted from 94 stool samples by two methods: QIAamp Viral RNA Mini kit and MagNA Pure 96 automate. The Altona results were compared to a reference laboratory-developed accredited ISO15189 RT-PCR assay. Results The Altona and reference assays detect HEV RNA in 77/93 (82.8%) and 83/93 (89.2%) of the QIAamp extracted samples, respectively, after exclusion of invalid result; they detected HEV RNA in 67/92 (72.8%) and 66/92 (71.7%) of the MagNA Pure extracted samples, respectively, which emphasizes the importance of the RNA extraction method. The HEV RNA concentrations obtained with Altona RT-PCR and the reference RT-PCR were well correlated whatever the extraction method, and Bland Altman analyses indicated that the Altona values were higher than the reference assay values. The Altona values for QIAamp-extracted and MagNA Pure-extracted HEV RNA were very similar. Conclusions The Altona RealStar assay is suitable for quantifying HEV RNA in the faeces and monitoring HEV RNA shedding during ribavirin therapy. Extraction is critical for detecting faecal HEV with high performance RT-PCR assays.

Abstract
The incidence and prevalence of hepatitis E virus (HEV) infection has increased in many developed countries over the last decade, predominantly due to infection with genotype 3 (G3) HEV. Infection with HEV G3 is important in transplant recipients because it can persist in immunosuppressed individuals, leading, if untreated, to the development of chronic hepatitis and significant liver fibrosis. The British Transplantation Society (BTS) has developed Guidelines for "Hepatitis E and Solid Organ Transplantation" to inform clinical teams and patients about hepatitis E, to help increase the recognition of persistent hepatitis E infection, and to provide clear guidance on its management. This guideline was published on the BTS website in June 2017 and aims to review the evidence relating to the diagnosis and management of persistent hepatitis E in solid organ transplant recipients and the methods of prevention of HEV infection. In line with previous guidelines published by the BTS, the guideline has used the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system to rate the strength of evidence and recommendations. This article includes a summary overview of hepatitis E and transplantation with key references, and the statements of recommendation contained within the guideline. It is recommended that the full guideline document is consulted for complete details of the relevant references and evidence base. This may be accessed at https://bts.org.uk/guidelines-standards/.

Abstract
Hepatitis E is an acute self-limiting disease caused by hepatitis E virus (HEV). Recent reports show that HEV can induce chronic hepatitis or be reactivated in immunocompromised hosts. We report a 63-year-old woman with rheumatoid arthritis (RA) who developed hepatitis E during treatment with tocilizumab. Analysis of serially stocked serum samples confirmed that hepatitis was caused by primary infection with HEV and not by viral reactivation. Her liver function improved after discontinuing tocilizumab and remained within the normal range without reactivation of HEV for >5 years after restarting tocilizumab. We also reviewed the published cases of hepatitis E that developed during RA treatment.

Abstract
BACKGROUND Hepatitis E virus (HEV) infection in immunocompromised patients such as solid organ transplant recipients may bear a high risk of becoming a chronic infection with progression to liver cirrhosis. So far, data on HEV infection in pediatric renal transplant recipients are limited. METHODS This single-center cohort study investigated period prevalence, morbidity, and treatment of HEV infection in 90 pediatric renal allograft recipients aged 9.9 ± 5.6 years at transplantation (58.9% males). HEV serology was determined by enzyme-linked immunosorbent assay and immunoblot, HEV replication by quantitative nucleic acid testing. RESULTS Twelve of 90 (13.3%) patients were HEV seropositive, and 4/90 (4.4%) recipients showed active HEV replication (103-108 copies/mL, corresponding to 0.5 × 103 and 0.5 × 108 WHO IU/mL) in serum and stool. In all patients with HEV replication, genotype 3 was identified by partial sequencing of HEV ORF1 and ORF2 and phylogenetic analysis. All patients with HEV replication developed chronic infection associated with moderately elevated liver enzymes. HEV replication was unresponsive to reduction of immunosuppression, whereas ribavirin monotherapy (mean dosage 9.7 ± 3.6 mg/kg per day over 85 ± 11 days) was associated with sustained viral clearance and normalization of liver enzymes in all patients. Ribavirin therapy was associated with reversible, hyporegenerative anemia. CONCLUSIONS Given an HEV seroprevalence of 13.3% in pediatric renal transplant recipients and an HEV viremia of 4.4%, HEV infection should be considered in patients with otherwise unexplained elevation of liver enzymes. HEV infection does not necessarily respond to reduction of immunosuppressive therapy, but can be effectively and safely treated with ribavirin.

Abstract
Hepatitis E virus infection is usually a self-limited disease. However, during the last years there has been growing evidence for prolonged and chronic infection occurring in patients with immunosuppression. Also patients with malignant and rheumatic diseases have been identified to be at risk for chronic hepatitis E. However, their course and prognosis are not well characterized and there have been no reports of hepatitis E virus infection in patients with gynecological cancer. Here, we report three Caucasian females with breast and ovarian cancers presenting with elevation of aminotransferase levels during anticancer treatment. Although only few or no clinical hints suggested hepatitis E virus infection, the diagnosis of hepatitis E virus infection was confirmed by seroconversion, which might occur with some delay, and/or by polymerase chain reaction. While two patients had a self-limited course, the third patient with a high-risk oncological constellation required ribavirin in order to resume chemotherapy. These cases highlight the need for hepatitis E virus testing in patients with gynecological cancer and elevated aminotransferase levels. Further, these cases show that in selected high-risk patients, ribavirin treatment may be necessary based on the decision of a multidisciplinary team.

Abstract
INTRODUCTION Hepatitis E virus (HEV) is an emerging cause of autochthonous-acute-hepatitis and acute-on-chronic-liver-failure in western countries. Treatment is not routinely used, despite ribavirin has a good antiviral effect. In vitro sofosbuvir inhibits HEV replication, but clinical data are lacking. CASE REPORT We report a case of acute-on-chronic-liver-failure due to HEV treated with sofosbuvir and ribavirin. The treatment was capable of rapidly inducing both HCV and HEV viral suppression. CONCLUSION In conclusion, although more data are required before firm conclusions could be drawn, the combination of sofosbuvir and ribavirin in not immunosuppressed patients with acute hepatitis E may be able to clear HEV infection.

Abstract
Hepatitis E virus genotype 3 (HEV-3) can lead to chronic infection in immunocompromised patients, and ribavirin is the treatment of choice. Recently, mutations in the polymerase gene have been associated with ribavirin failure but their frequency before treatment according to HEV-3 subtypes has not been studied on a large data set. We used single-molecule real-time sequencing technology to sequence 115 new complete genomes of HEV-3 infecting French patients. We analyzed phylogenetic relationships, the length of the polyproline region, and mutations in the HEV polymerase gene. Eighty-five (74%) were in the clade HEV-3efg, 28 (24%) in HEV-3chi clade, and 2 (2%) in HEV-3ra clade. Using automated partitioning of maximum likelihood phylogenetic trees, complete genomes were classified into subtypes. Polyproline region length differs within HEV-3 clades (from 189 to 315 nt). Investigating mutations in the polymerase gene, distinct polymorphisms between HEV-3 subtypes were found (G1634R in 95% of HEV-3e, G1634K in 56% of HEV-3ra, and V1479I in all HEV-3efg, clade HEV-3ra, and HEV-3k strains). Subtype-specific polymorphisms in the HEV-3 polymerase have been identified. Our study provides new complete genome sequences of HEV-3 that could be useful for comparing strains circulating in humans and the animal reservoir.

Abstract
BACKGROUND AND OBJECTIVES We evaluated the performance of the Procleix HEV RNA assay implemented on the Panther automated platform for detecting HEV RNA. STUDY DESIGN AND RESULTS Analytical specificity was 100% and there was no cross contamination, as assessed by assaying 122 plasma samples from HEV RNA-negative blood donors. The limits of detection were determined by Probit analysis with the WHO HEV standard (HEV subtype 3a) and subtype 3f and 3c reference strains. The limit of detection was 24 [CI 95%: 19-33] IU/ml for subtype 3a, 34 [28-44] IU/ml for subtype 3c and 53 [41-76] IU/ml for subtype 3f. Inclusivity was assessed by testing 91 samples: HEV genotype 3 subtypes 3c (n = 29), 3e (n = 8), 3f (n = 50), genotype 4 (n = 3), and genotype 1 (n = 1). All the samples tested positive. Clinical performance was determined by testing prospectively 500 consecutive plasma samples and 19 faecal samples with the Procleix assay and a reference accredited quantitative RT-PCR assay. The assays were concordant for 492/500 plasma samples (98.4%) and 18/19 (94.7%) fecal samples. We also tested 92 IgM-positive/HEV RNA-negative samples with the reference assay. The IgM-positive samples included 43 (46%) that tested negative with the reference RT-PCR assay and positive with the Procleix HEV assay. CONCLUSIONS The Procleix HEV assay performed well and appears to be suitable for molecular diagnosis of HEV infection, monitoring HEV infections, and facilitating epidemiological investigations.

Abstract
HEV infection can lead to chronic hepatitis in immunosuppressed patients; extrahepatic manifestations are rarely seen. Here, we report a 13-year-old renal transplant patient with chronic hepatitis E and renal involvement. Ribavirin therapy led to temporary virus clearance and amelioration of kidney function. However, ribavirin therapy caused severe hyporegenerative anemia, which has so far only been reported in patients treated with a combination of ribavirin and interferon alpha.

Abstract
Infection with hepatitis E virus (HEV) is a significant cause of morbidity and mortality, representing an important global health problem. Our understanding of HEV has changed completely over the past decade. Previously, HEV was thought to be limited to certain developing countries. We now know that HEV is endemic in most high-income countries and is largely a zoonotic infection. Given the paradigm shift in our understanding of zoonotic HEV and that locally acquired HEV is now the commonest cause of acute viral hepatitis in many European countries, the focus of these Clinical Practice Guidelines will be on HEV genotype 3 (and 4).

Abstract
Hepatitis E virus (HEV) is a positive-strand RNA virus transmitted by the fecal–oral route. HEV genotypes 1 and 2 infect only humans and cause mainly waterborne outbreaks. HEV genotypes 3 and 4 are widely represented in the animal kingdom, and are mainly transmitted as a zoonosis. For the past 20 years, HEV infection has been considered an imported disease in developed countries, but now there is evidence that HEV is an underrecognized pathogen in high-income countries, and that the incidence of confirmed cases has been steadily increasing over the last decade. In this review, we describe current knowledge about the molecular biology of HEV, its clinical features, its main routes of transmission, and possible therapeutic strategies in developed countries.

Abstract
Hepatitis E virus (HEV) is the most common cause of viral hepatitis worldwide. Genotypes 1 and 2 (GT1 and GT2) are mainly present in developing countries, while GT3 and GT4 are prevalent in developed and high-income countries. In the majority of cases, HEV causes a self-limiting hepatitis. GT3 and GT4 can be responsible for a chronic hepatitis that can lead to cirrhosis in immunocompromized patients, i.e. solid-organ- and stem-cell-transplant-patients, human immunodeficiency virus-infected patients, and patients receiving chemotherapy or immunotherapy. HEV has also been associated with extra-hepatic manifestations such as neurologic disorders (Guillain-Barré Syndrome and neuralgic amyotrophy) and kidney disease. In patients with chronic hepatitis, reduction of immunosuppression, when possible, is the first therapeutic option. In the remaining patients, ribavirin therapy has been shown to very efficient for treating HEV infection leading to a sustained virological response in nearly 80-85% of patients. However, the mechanism of action of ribavirin in this setting is still unknown, as is the impact of HEV RNA polymerase mutations. There are unmet needs with regard to the treatment of chronic HEV with ribavirin. These include the optimal dosing and duration of treatment, and the potential beneficial effects of therapeutic drug monitoring on the virological response and the incidence of side effects. In the present review, we will provide an overview of HEV epidemiology, its mode of transmission and clinical manifestations, as well as its treatment by ribavirin with a focus on the drug's pharmacokinetics and dosing.

Abstract
In recent years there has been a paradigm shift in our understanding of the epidemiology and clinical features of hepatitis E virus (HEV) infection. Once classically described as an acute hepatitis associated with waterborne outbreaks in areas of poor sanitation, HEV is now recognised to be endemic in Europe and is probably zoonotic in origin. Evidence for transfusion-transmitted HEV has prompted the introduction of blood donor screening in a number of countries, but the risk to the haematology patient from food sources remains. The aim of this review therefore, is to equip the clinical haematologist with the knowledge required to diagnose HEV infection and to aid decision-making in patient management. The article also provides information on addressing patient concerns about their risk of acquiring hepatitis E and how this risk can be mitigated.

Abstract
INTRODUCTION Infection with HBV and HCV represents a growing challenge in the management of patients with hematological malignancies. Recently, hepatitis E (HEV) was recognized as an endemic infection in developed countries and as an emerging health problem in immunocompromised patients. Areas covered: We reviewed the current knowledge on the impact of chronic viral hepatitis in the hematological setting. Epidemiological features, screening strategies and indications for treatment and monitoring have been explored and commented. Expert commentary: Knowing patient's complete HBV serostatus is mandatory in order to choose between treatment, prophylaxis or a pre-emptive approach. Recent guidelines favor treatment with high barrier molecules in all patients with chronic HBV infection and long lasting prophylaxis with those with inactive or resolved one. With regard to HCV, the new direct-acting antiviral agents have been safely administered in the hematological setting. Their use as first-line single treatment in indolent lymphomas, and combined with chemotherapy in aggressive ones, should be considered. Due to the existing risk of chronic HEV infection in the immunocompromised, screening with serum HEV-RNA should be performed in case of signs and symptoms indicative of hepatitis. In the event of HEV infection, reduction of immunosuppression and, if not feasible or unsuccessful, ribavirin treatment should be prescribed.

Abstract
HEV infections are mainly food- and water-borne but transfusion-transmission has occurred in both developing and developed countries. The infection is usually asymptomatic but it can lead to fulminant hepatitis in patients with underlying liver disease and pregnant women living in developing countries. It also causes chronic hepatitis E, with progressive fibrosis and cirrhosis, in approximately 60 % of immunocompromised patients infected with HEV genotype 3. Extra-hepatic manifestations such as neurological and renal manifestations have been reported. The risk of a transfusion-transmitted HEV infection is linked to the frequency of viremia in blood donors, the donor virus load and the volume of plasma in the final transfused blood component. Several developed countries have adopted measures to improve blood safety based on the epidemiology of HEV.

Abstract
We present a 38-year-old white British man who was taking long-term immunosuppressive medication following kidney transplantation. On routine review, he was noted to have an isolated and asymptomatic rise in alanine aminotransferase. After thorough investigation, he was found to have positive IgM and IgG serology to hepatitis E virus-and given the duration of his transaminitis, he was determined to have chronic hepatitis E infection. Treatment options were complicated by the presence of his kidney transplant, by chronic anaemia and by his wish for concomitant fertility treatment. Ribavirin therapy was instituted with a dramatic and immediate drop in serum viral load, although stool viraemia persisted. No clear protocols guide duration of treatment in chronic hepatitis E infection, but protracted faecal virus shedding predicts viral recrudescence, and treatment should continue at least until the stool is clear of virus.

Abstract
At least 20 million hepatitis E virus (HEV) infections occur annually, with >3 million symptomatic cases and ∼60,000 fatalities. Hepatitis E is generally self-limiting, with a case fatality rate of 0.5-3% in young adults. However, it can cause up to 30% mortality in pregnant women in the third trimester and can become chronic in immunocompromised individuals, such as those receiving organ transplants or chemotherapy and individuals with HIV infection. HEV is transmitted primarily via the faecal-oral route and was previously thought to be a public health concern only in developing countries. It is now also being frequently reported in industrialized countries, where it is transmitted zoonotically or through organ transplantation or blood transfusions. Although a vaccine for HEV has been developed, it is only licensed in China. Additionally, no effective, non-teratogenic and specific treatments against HEV infections are currently available. Although progress has been made in characterizing HEV biology, the scarcity of adequate experimental platforms has hampered further research. In this Review, we focus on providing an update on the HEV life cycle. We will further discuss existing cell culture and animal models and highlight platforms that have proven to be useful and/or are emerging for studying other hepatotropic (viral) pathogens.

Abstract
PURPOSE OF REVIEW Over the last 10 years, it has become apparent that hepatitis E virus (HEV) is a pathogen of global significance. In contrast to HEV in the developing world, HEV in developed countries is caused by HEV genotypes 3 and 4, which are enzoonotic with a porcine primary host and cause both acute and chronic infection. Chronic infection occurs in the immunosuppressed, including transplant recipients, and untreated can cause rapidly progressive cirrhosis. RECENT FINDINGS Ribavirin has been used successfully to treat acute hepatitis E in high-risk patients. Ribavirin monotherapy is the treatment of choice for patients chronically infected with HEV, with sustained virological response (SVR) of approximately 85%. A minority of chronically infected patients fail to achieve SVR with ribavirin monotherapy, possibly because of viral mutants. The treatment of patients who fail to achieve SVR with ribavirin monotherapy is problematic. SUMMARY Ribavirin is an effective treatment for hepatitis E, but further studies are required to determine which other antiviral agents are of clinical utility in treating HEV in the minority of patients who do not respond to ribavirin.

Abstract
Hepatitis E is the fifth known form of human viral hepatitis. Although not very common in our clinical practice, the incidence in Western countries is increasing. Infection with the hepatitis E virus (HEV) may be related to acute illness, liver failure, chronic hepatitis and cirrhosis. HEV itself is an RNA virus, with eight described genotypes (HEV 1-8), four of which more commonly affect humans and have, thus, been better studied. Besides liver manifestations, genotype 3 is also related to extra-hepatic manifestations, such as neurological, renal and rheumatological. Evolution to chronic disease occurs especially in patients who underwent transplantation, have hematological malignancies requiring chemotherapy, or have infection with the human immunodeficiency virus. The diagnosis may be difficult because of the low availability of tests and due to low sensibility and specificity. The acute form of illness does not have to be treated, but the chronic one does. We present here a literature review of hepatitis E and the relation between chronic hepatitis E and transplantation.

Abstract
Viral hepatitis contributes to significant morbidity and mortality worldwide. While acute infection may be self-limiting, unrecognised chronic infection and under-utilisation of guideline-based approaches to therapy contribute to increasing rates of cirrhosis, hepatocellular carcinoma and death. Our aim was to review the current evidence for screening, diagnosis and treatment in hepatitis A to E. Evidence for this review was sourced from international and Australian guidelines and high-quality clinical trials. MEDLINE was searched using structured key word strategy and retrieved articles were reviewed methodically to inform a brief and up-to-date synopsis of hepatitis A to E. We share some of the recent developments in viral hepatitis, specifically the new therapies for hepatitis C. Direct-acting antiviral therapies are safe, well-tolerated and effective. Subsidies allow access for all Australians with most strains of hepatitis C. We outline evidence underpinning efficacy and safety of treatment for hepatitis B, while clarifying some of the nuances in the setting of pregnancy and immunosuppression. We provide a simplified concept to facilitate understanding of the five phases of hepatitis B; practical for real-world setting. Hepatitis A to E is a broad topic, not all aspects of these viruses can be covered in this short review. We provided suggestions for evidence based guidelines, which are a suitable supplement to this article.

Abstract
Hepatitis E virus (HEV) infection which may become fulminant, especially in elderly people is more common than previously recognized in develop countries. Here we report successful living-donor liver transplantation (LDLT) in a case of acute liver failure due to HEV. A 63-year-old Japanese man with no previous history of liver disease was admitted for severe acute hepatitis. Detection of anti-HEV immunoglobulin A established a diagnosis of this virus-related liver failure. The patient suffered from hepatic encephalopathy 10 days after symptom onset and underwent LDLT. The patient had an uneventful course. The HEV RNA showed spontaneous negative conversion 10 weeks after LDLT. LDLT led to a successful outcome in a patient with acute liver failure due to HEV infection and regular testing for HEV RNA should be performed until HEV RNA is undetectable.

Abstract
Hepatitis E virus (HEV) is a quasi-enveloped, single-stranded positive-sense RNA virus. HEV belongs to the family Hepeviridae, a family comprised of highly diverse viruses originating from various species. Since confirmation of HEV's zoonosis, HEV-induced hepatitis has been a public health concern both for developing and developed countries. Meanwhile, the demonstration of a broad host range for zoonotic HEV suggests the existence of a variety of transmission routes that could lead to human infection. Moreover, anti-HEV antibody serosurveillance worldwide demonstrates a higher than expected HEV prevalence rate that conflicts with the rarity and sporadic nature of reported acute hepatitis E cases. In recent years, chronic HEV infection, HEV-related acute hepatic failure, and extrahepatic manifestations caused by HEV infection have been frequently reported. These observations suggest a significant underestimation of the number and complexity of transmission routes previously predicted to cause HEV-related disease, with special emphasis on zoonotic HEV as a public health concern. Significant research has revealed details regarding the virology and infectivity of zoonotic HEV in both humans and animals. In this review, the discovery of HEV zoonosis, recent progress in our understanding of the zoonotic HEV host range, and classification of diverse HEV or HEV-like isolates from various hosts are reviewed in a historic context. Ultimately, this review focuses on current understanding of viral pathogenesis and cross-species transmission of zoonotic HEV. Moreover, host factors and viral determinants influencing HEV host tropism are discussed to provide new insights into HEV transmission and prevalence mechanisms.

Hepatitis E virus-induced primary cutaneous CD30(+) T cell lymphoproliferative disorder. J Hepatol 2017; 67:1334-1339. [PMID: 28860025 DOI: 10.1016/j.jhep.2017.08.011] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2017] [Revised: 08/07/2017] [Accepted: 08/17/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIM Several types of unexplained extra-hepatic manifestations, including haematological disorders, have been reported in the context of hepatitis E virus (HEV) infection. However, the underlying mechanism(s) of these manifestations are unknown. We provide evidence that HEV has an extra-hepatic endothelial tropism that can engage cutaneous T cells towards clonality. METHODS A patient with a CD30(+) cutaneous T cell lymphoproliferative disorder (T-LPD) and biopsy-proven chronic HEV infection received three rounds of oral ribavirin treatment, administered either without or with interferon, and eventually achieved a sustained virologic response (SVR). Pathologic, virologic and immunologic investigations were carried out on biopsied skin lesion, and peripheral blood mononuclear cells between the 2nd and 3rd round of antiviral treatment and biopsied liver. RESULTS Remission of T-LPD was observed upon antiviral treatment, and the patient remained in complete remission after achieving SVR. The T cell analysis showed large CD30(+) lymphocytes surrounding the blood vessels within the CD8(+) T cell infiltrate. HEV was detected within dermal microvascular endothelial cells using immunofluorescence staining, in situ hybridisation and electron microscopy. Infiltrating T cells mostly comprised memory CD8(+) T cells with a tissue-resident memory T cell phenotype. Overall, 98% of extracted T cells were CD8(+) T cells with aVβ signature skewed towards Vβ4 and with an oligoclonal profile. T cell clones from T-LPD were more like T cells in the liver than T cells in the blood [odds ratio=4.55, (3.70-5.60), p<0.0001]. No somatic mutations were found in the T-LPD exomes. CONCLUSION HEV has an extra-hepatic tissue tropism in humans, including dermal endothelium, and can induce CD30(+) T-LPD that is sensitive to antivirals. LAY SUMMARY Hepatitis E virus (HEV) has an extra-hepatic tissue tropism and should be added to the list of viruses associated with lymphoproliferative disorders. As such, HEV should be part of the laboratory workup of any lymphoproliferation, particularly those of the T cell phenotype that involve the skin. In the context of HEV-associated cutaneous T cell lymphoproliferative disorders, antiviral treatment could be considered a first-line treatment instead of chemotherapy.
