Hepatitis E, which is caused by hepatitis E virus (HEV), is a public health concern in Japan, where the zoonotic food-borne transmission of HEV from domestic pigs and wild boars plays an important role. A 44-year-old Japanese man with autochthonous sporadic acute hepatitis E was admitted with general fatigue and moderate liver dysfunction. In the present study, two distinct HEV strains were recovered from the patient, who had consumed the raw or undercooked pig liver and intestine two or three times per week for 3 months before the disease onset...

Hepatitis E virus (HEV) infection is an emerging disease with zoonotic transmission that represents a serious public health concern, especially in developing countries. Here we characterize a novel HEV strain CCST-517, which possesses a complete genome sequence of 7284 bp with typical HEV genome organization including 5' and 3' non-coding regions and three open reading frames. The sequence identities of CCST-517 with known HEV genotype 1, 2, 3, and 4 were 73.4-73.7, 73.2, 80.4-90.4, and 75.1-75.7%, respectively...

Hepatitis E virus (HEV) causes substantial morbidity and mortality in developing countries and is considered an emerging food-borne pathogen in previously non-endemic developed countries. To investigate genetic association between human HEV infection and HEV-contaminated high-risk food in Hong Kong, we compared local virus strains obtained from hepatitis E patient sera with those surveyed from high-risk food items during 2014-2016. Twenty-four cases of laboratory-confirmed human HEV infections were identified from January 2014 to March 2016 in our hospitals...

The majority of patients with acute febrile jaundice (>95%) identified through a yellow fever surveillance program in the Democratic Republic of Congo (DRC) test negative for antibodies against yellow fever virus. However, no etiological investigation has ever been carried out on these patients. Here, we tested for hepatitis A (HAV), B (HBV), C (HCV), D (HDV) and E (HEV) viruses, all of which can cause acute febrile jaundice, in patients included in the yellow fever surveillance program in the DRC. On a total of 498 serum samples collected from suspected cases of yellow fever from January 2003 to January 2012, ELISA techniques were used to screen for antibodies against HAV (IgM) and HEV (IgM) and for antigens and antibodies against HBV (HBsAg and anti-HBc IgM), HCV and HDV...

Hepatitis E virus (HEV) is the most common cause of acute viral hepatitis globally. HEV comprises four genotypes with different geographic distributions and host ranges. We utilise this natural case-control study for investigating the evolution of zoonotic viruses compared to single host viruses, using 244 near full length HEV genomes. Genome wide estimates of dN/dS located a region of overlapping reading frames, which is subject to positive selection in genotypes 3 and 4. The open reading frames (ORFs) involved have functions related to host-pathogen interaction, so genotype specific evolution of these regions may reflect their fitness...

Infection with the hepatitis E virus (HEV) is very common worldwide. HEV causes acute viral hepatitis with approximately 20 million cases per year. While HEV genotypes 1 and 2 cause large waterborne and foodborne outbreaks with a significant mortality in developing countries, genotypes 3 and 4 are more prevalent in developed countries with transmission being mostly zoonotic. In North America and Europe, HEV has been increasingly detected in swine, and exposure to pigs and pork products is considered to be the primary source of infection...

Background and Aims: As the predominant lymphocyte subset in the liver, natural killer (NK) cells have been shown to be highly associated with the outcomes of patients with chronic hepatitis B virus infection (CHB) and hepatocellular carcinoma (HCC). Previously, we reported that NKG2A, a checkpoint candidate, mediates human and murine NK cell dysfunction in CHB. However, NK cell exhaustion and, particularly, the level of NKG2A expression within liver tumors have not been reported. Methods: In this study, we analyzed NKG2A expression and the related dysfunction of NK cells located in intra- or peritumor regions of liver tissue samples from 207 HCC patients, in addition to analyzing disease outcomes...

Hepatitis C virus (HCV) infection is a major health burden worldwide. A patient with no history of HCV infection while on a renal unit was found to seroconvert to HCV. Here we report the use of sequencing to postulate how transmission of HCV occurred in a healthcare setting, and how this guided our outbreak investigation. Based on infection control inspections the transmission event was surmised to be due to ward environmental contamination with blood and subsequent inoculation from intravenous interventions on the patient acquiring HCV...

BACKGROUND: In hepatitis B virus (HBV) infected patients, hepatitis B e antigen (HBeAg) seroconversion is associated with better outcomes. Interleukin-18 (IL-18) controls hepatitis B replication in a mouse model. However, its role in treatment response in HIV/HBV co-infected patients is unknown. METHODS: We enrolled 35 treatment-naïve, HBeAg positive, HIV/HBV co-infected patients. HBV DNA, HIV RNA, CD4 cell count, HBV surface antigen (HBsAg) quantification (qHBsAg), HBeAg quantification (qHBeAg) and IL-18 levels were measured prior to, at 24 and 48 weeks of HBV-active combination antiretroviral therapy (cART)...

: Interferons (IFNs) are broad antiviral cytokines that exert their function by inducing the transcription of hundreds of interferon-stimulated genes (ISGs). However, little is known about the antiviral potential of these cellular effectors on hepatitis E virus (HEV) infection, the leading cause of acute hepatitis globally. In this study, we profiled the antiviral potential of a panel of important human ISGs on HEV replication in cell culture models by overexpression of individual ISG...

BACKGROUND: Infection with hepatitis E virus (HEV) Genotype 3 is recognized as a food-borne zoonosis in developed countries where it usually causes a mild self-limited acute hepatitis. It may cause a persistent infection in the immunosuppressed human that can progress to cirrhosis. To protect the patient from transfusion-acquired HEV infection, steps have been taken in the United Kingdom to provide for at-risk patients only components from donors screened for HEV viremia. This strategy does not protect from dietary exposure and calls into question estimation of relative risk between blood transfusion and diet...
