Outbreaks of hepatitis A virus (HAV) infection have been occurring among men who have sex with men (MSM) in Asia-Pacific region, the United States, and several European countries since June 2015, and recently among persons who are homeless and use illicit drugs in the US. We evaluated the serologic responses and effectiveness of HAV vaccination in HIV-positive individuals during the outbreak in Taiwan. From June 1, 2015 to September 30, 2016, anti-HAV IgG was prospectively determined among all HIV-positive individuals...

The current hepatitis A outbreak in Europe is largely involving men having sex with multiple male partners. The objective of the present report was to warn teams dealing against the persistent risk of viral and bacterial sexually transmitted infection (STIs) in patients receiving HIV pre-exposure prophylaxis (PrEP). We have notified and investigated three cases of acute hepatitis A virus (HAV) infection in people receiving HIV PrEP in our clinic between December 2016 and March 2017. The patients were not epidemiologically related, had no recent travel history to HAV endemic areas, reported multiple STIs during this period and had not been vaccinated against HAV...

The European Pharmacopoeia (Ph. Eur.) standard ELISA method for determination of antigen content of hepatitis A vaccines (HAV) requires specific coating and detection Biological Reference Reagents (BRRs). The 3rd batch of detection antibodies BRRs was established in 2015 for use in conjunction with the Ph. Eur. general chapter 2.7.14 'Assay of hepatitis A vaccine'. Stocks of these BRRs were running low and therefore the European Directorate for the Quality of Medicines & HealthCare (EDQM) organised a collaborative study to qualify replacement batches...

Hepatitis A is a worldwide vaccine-preventable infection. The aim of our study was to determine the serological status of hepatitis A virus (HAV) among first-year nursing students in Turkey. A sample of 423 students was used and immunoglobulin G antibodies against HAV were determined quantitatively by enzyme-linked immunosorbent assay on each. Overall, 84.6% had no immunity to HAV, making them at risk for HAV, and so susceptible to nosocomial transmission. Nursing students who work in high-risk wards must be vaccinated against hepatitis A...

Hepatitis C virus (HCV) is the leading cause of chronic hepatitis in humans. Several host molecules participate in HCV cell entry but this process remains unclear. The complete unraveling of the HCV entry process is important to further understand viral pathogenesis and develop therapeutics. The human hepatitis A virus (HAV) cellular receptor 1 (HAVCR1), CD365, also known as TIM-1, functions as a phospholipid receptor involved in cell entry of several enveloped viruses. Here, we studied the role of HAVCR1 in HCV infection...

There is heterogeneity in the literature regarding the anatomy, exact location, and definition of the intersesamoid ligament (IL). Anatomic knowledge of the IL and its variations are important for surgeons who undertake corrective surgery for hallux abducto valgus (HAV). The IL was dissected in 16 feet from 32 formalin-fixed cadavers (12 females, four males; mean age at death, 76.6 years) to examine its morphology. The length, width, and thickness of its constituent bands were recorded with a digital caliper...

Acute hepatitis A (AHA) involves severe CD8+ T cell-mediated liver injury. Here we showed during AHA, CD8+ T cells specific to unrelated viruses became activated. Hepatitis A virus (HAV)-infected cells produced IL-15 that induced T cell receptor (TCR)-independent activation of memory CD8+ T cells. TCR-independent activation of non-HAV-specific CD8+ T cells were detected in patients, as indicated by NKG2D upregulation, a marker of TCR-independent T cell activation by IL-15. CD8+ T cells derived from AHA patients exerted innate-like cytotoxicity triggered by activating receptors NKG2D and NKp30 without TCR engagement...

Hepatitis A (HA) is caused by a hepatovirus from the family Picornaviridae (Hepatitis A Virus, HAV). Transmission occurs mainly by the orofaecal route through food or water contaminated by faeces. Sexual transmission has also been reported among men who have sex with men (MSM). From February to May 2017, 14 patients with HA were hospitalized at the University Hospital "Maggiore della Carità", Novara (Eastern Piedmont), Italy. One patient was two years old and was therefore admitted to the Paediatric Unit, the remaining 13 to the Infectious Disease Unit...

Viral hepatitis is the most common cause of serious health problems such as liver cirrhosis and hepatocellular carcinoma (HCC). Leading to immunodeficiency disorders through different mechanisms, Human Immunodeficiency Virus (HIV) causes the development of severe secondary infections. Hepatitis A (HAV) is thought to spread by the faecal-oral route, while Hepatitis B (HBV), Hepatitis C (HCV) and HIV are mostly transmitted vertically during childhood. In our study, we aimed to determine the seroprevalence of HAV, HBV, HCV and HIV among Syrian refugee children who were admitted to outpatient clinics...

BACKGROUND: Among HIV-positive individuals, seroprotection for hepatitis A virus (HAV) following primary vaccination may wane with time. However, seroresponses to HAV revaccination are rarely investigated among HIV-positive patients who have lost protective antibodies after primary vaccination. METHODS: During the outbreak of acute hepatitis A in Taiwan after June 2015, HAV-seronegative, HIV-positive individuals were advised to receive 2 doses of HAV vaccines at 24 weeks apart...

Hemophagocytic lymphohistiocytosis (HLH) is a rare but severe and potentially fatal syndrome that can occur during pregnancy. A 36 years-old woman, at 29 weeks of gestation, presented with itchiness and jaundice since a week. On clinical examination she was apyrexial and frankly icteric. Laboratory data showed evidence of acute hepatitis. A complete work-up was made excluding viral hepatitis (HAV, HEV, HBV, HCV, HHV6, CMV, EBV) and autoimmune liver disease. Liver diseases related to pregnancy were not completely excluded...

Hepatitis A virus (HAV) and norovirus are important agents of food-borne human viral illness, with common vehicles including bivalve molluscan shellfish, soft fruit and various vegetables. Outbreaks of viral illness due to contamination of the surfaces of foods, or food preparation surfaces by for example infected food handlers are also common. Virus analysis of food matrices can contribute towards risk management for these hazards and a two-part technical specification for determination of Hepatitis A virus and norovirus in food matrices (ISO/TS 15216:2013) was published jointly by the European Committee for Standardisation and the International Organization for Standardization in 2013...

BACKGROUND: Synthetic expanded polytetrafluorethylene (ePTFE) grafts are routinely used for vascular repair and reconstruction but prone to sustained bacterial infections. Investigational bioengineered human acellular vessels (HAVs) have shown clinical success and may confer lower susceptibility to infection. Here we directly compared the susceptibility of ePTFE grafts and HAV to bacterial contamination in a preclinical model of infection. MATERIALS AND METHODS: Sections (1 cm2) of ePTFE (n = 42) or HAV (n = 42) were inserted within bilateral subcutaneous pockets on the dorsum of rats and inoculated with Staphylococcus aureus (107 CFU/0...

BACKGROUND: Vaccination for hepatitis A virus (HAV) has been implemented as one of the national vaccination programs despite the epidemiological transition of HAV in the Republic of Korea. While the national HAV vaccination program is largely associated with the shift of socioeconomic trend in the country, concerns have been raised on the effectiveness of the HAV immunization. The objective of this study was to examine the epidemiological trend of HAV and assess the effectiveness of the nationwide HAV vaccination policy based on a nationally representative sample of the Korean population collected in 2015...

Since 2016, an increase in the number of hepatitis A cases affecting mainly men who have sex with men (MSM) has been reported in low endemic countries in Europe. We calculated the attack rate in Lyon, France, in populations considered at high-risk: HIV-infected MSM and HIV-negative MSM receiving HIV pre-exposure prophylaxis (PrEP). In these populations, high level of immunity did not prevent the outbreak, indicating that vaccination should be reinforced, particularly in younger individuals.

Hepatitis A virus (HAV) is well known worldwide as a causative virus of acute hepatitis. In recent years, numerous cases of HAV infection caused by HAV-contaminated berries have occurred around the world. Because berries are often consumed without prior heating, reliable disinfection of the raw fruit is important in order to prevent HAV outbreaks. Previous studies have found that murine norovirus strain 1 (MNV-1) and human norovirus GII.4 were inactivated in heat-denatured lysozyme solution. In this study, we investigated whether or not heat-denatured lysozyme is effective in inactivating HAV and whether it could be an effective disinfectant for berries contaminated with HAV or MNV-1...

BACKGROUND: In Switzerland, intravenous drug use accounts for the majority of hepatitis C virus (HCV) infections. Early HCV treatment prevents further transmissions and reduces morbidity and mortality due to decompensated liver cirrhosis and hepatocellular carcinoma. Nevertheless, patients in drug substitution programmes are often insufficiently screened and treated. AIM: The aim was to compare the current state of HCV management in centralised and decentralised drug substitution programmes of the canton Aargau...
