Abstract
Acute hepatitis E was considered rare until reports emerged affirming the existence of hepatitis E virus (HEV) genotypes 3 and 4 infections in Japan in the early 2000s. Extensive studies by Japanese researchers have highlighted the pivotal role of pigs and wild animals, such as wild boars and deer, as reservoirs for HEV, linking them to zoonotic infections in Japan. Currently, when hepatitis occurs subsequent to the consumption of undercooked or grilled pork, wild boar meat, or offal (including pig liver and intestines), HEV infection should be considered. Following the approval of anti-HEV immunoglobulin A antibody as a diagnostic tool for hepatitis E by Japan's Health Insurance System in 2011, the annual number of diagnosed cases of HEV infection has surged. Notably, the occurrence of post-transfusion hepatitis E promoted nationwide screening of blood products for HEV using nucleic acid amplification tests since 2020. Furthermore, chronic hepatitis E has been observed in immunosuppressed individuals. Considering the significance of hepatitis E, heightened preventive measures are essential. The Japan Agency for Medical Research and Development Hepatitis A and E viruses (HAV and HEV) Study Group, which includes special virologists and hepatologists, held a virtual meeting on February 17, 2024. Discussions encompassed pathogenesis, transmission routes, diagnosis, complications, severity factors, and ongoing and prospective vaccination or treatments for hepatitis E. Rigorous assessment of referenced studies culminated in the formulation of recommendations, which are detailed within this review. This comprehensive review presents recent advancements in HEV research and Japanese clinical practice guidelines for HEV infection.

Prevalence and incidence of HEV among men using HIV pre-exposure prophylaxis: A sub-study of the ANRS IPERGAY trial. J Clin Virol 2023; 160:105380. [PMID: 36638749 DOI: 10.1016/j.jcv.2023.105380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/03/2023] [Accepted: 01/05/2023] [Indexed: 01/11/2023]
Abstract
BACKGROUND Men who have sex with men (MSM) have an increased risk of infection by pathogens transmitted by the oro-fecal route. Here, we investigated the seroprevalence and incidence of hepatitis E virus (HEV) infection in 416 MSM included in the ANRS IPERGAY PrEP trial. RESULTS Among the 62 (14.9% (95% CI: [11.6%-18.7%]) seropositive for HEV at inclusion, the only factor associated with testing seropositive for HEV was older age. Geographical origin, use of recreational drugs, number of sexual partners, status for HAV and bacterial sexually transmitted infection (STI) at inclusion were not associated. Among the 342 HEV-seronegative patients with available samples, 9 seroconverted after a median of follow-up of 2.1 years (IQR (interquartile range): [1.6; 3.0]). CONCLUSION Overall, the HEV incidence was 1.19% per 100 person-years [95% CI: 0.54%; 2.26%]. Sexual transmission does not seem to be a major route of HEV infection in MSM, unlike HAV.

Abstract
We investigated the seroprevalence and incidence of hepatitis E virus (HEV) infection in men who have sex with men (MSM) who have been exposed to pre-exposure prophylaxis (PrEP) against HIV as sexual transmission of HEV has been suggested. A total of 147 PrEP-using MSM and 147 blood donors matched for sex, age and geographical area were tested for anti-HEV IgG and IgM. Among them, 135 have been followed for 1 year, at the end of which serological tests for HEV were performed retrospectively on stored samples. Laboratory data on sexual transmitted infections (STIs) and viral hepatitis, including hepatitis A virus (HAV), were collected. Baseline seroprevalence rates in PrEP users were 42.2% (anti-HEV IgG) and 3.4% (anti-HEV IgM). Those of the control blood donors were similar (anti-HEV IgG 43.5% and anti-HEV IgM 4.1%). There was no incident of HEV infection despite the rates of bacterial STIs (incidence rate (IR) = 46.6%) and HAV infection (IR = 15.8%). Age was the only risk factor associated with anti-HEV IgG seropositivity at baseline and at the end of follow-up. Sexual transmission does not seem to be a major route of HEV infection in MSM, unlike HAV.

Hepatitis E virus infection prevalence among men who have sex with men involved in a hepatitis A virus outbreak in Italy. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2020; 17:428-432. [PMID: 31846607 DOI: 10.2450/2019.0209-19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Accepted: 09/23/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND The routes of hepatitis E virus (HEV) transmission have still not been fully clarified. Here, we evaluated the possibility of sexual transmission of HEV, which remains a highly disputed issue. MATERIALS AND METHODS Hepatitis E virus sexual transmission risk was assessed by comparing the prevalence of HEV infection in a sample of 196 Italian men who have sex with men (MSM) involved in a multi-country hepatitis A virus (HAV) outbreak, and in 3,912 Italian male blood donors selected from the same regions and provinces as the MSM. Selection of study of participants was motivated by the fact that HEV prevalence among Italian blood donors has been found to vary enormously between different geographical areas. RESULTS Anti-HEV IgG prevalence was 14.8% and 5.6% in blood donors and MSM, respectively. Adjusted anti-HEV IgG prevalence was significantly lower in MSM than in blood donors (odds ratio [OR], 0.40; 95% confidence interval [CI]: 0.22-0.75; p<0.01), among residents in northern (OR, 0.45; 95% CI: 0.37-0.55; p<0.01) and southern (OR, 0.45; 95% CI: 0.35-0.58; p <0.01) Italy than among residents in Central Italy, while the prevalence was significantly higher in participants over 50 years of age than in those under 50 years of age (OR, 1.83; 95% CI: 1.48-2.27; p<0.01). DISCUSSION Our findings suggest that sexual intercourse does not have a relevant role in HEV transmission. In particular, sexual transmission of HEV is unlikely to influence the prevalence of HEV infection at population level.

Abstract
Hepatitis E virus (HEV) and hepatitis A virus (HAV) are both secreted in feces. Despite HEV transmission in Europe is mainly zoonotic, person-to-person transmission has not been completely excluded. Men who have sex with men (MSM) constitute a high-risk group for HAV mostly due to oral sex. We investigated the potential transmission of HEV during an acute hepatitis A (AHA) outbreak mainly affecting MSM. One hundred and two patients were diagnosed with AHA. Sixty-nine (68%) self-reported to be MSM, 75% of whom had high-risk sexual behaviors and 46% had suffered previous sexually transmitted diseases. We collected serum from 85 (83%) patients during AHA. HEV-IgG seroprevalence was not different among MSM (7%) compared with non-MSM (8%) patients. Two patients had positive anti-HEV-IgM, but all samples tested negative for HEV-RNA. These results suggest that HEV does not spread by sexual contact or person-to-person in our area.
