HBV vaccination in HIV: immunogenicity and persistence of seroprotection up to 7 years following a primary immunization course.

AIDS Res Hum Retroviruses 2018 Jun 21. Epub 2018 Jun 21.

University of Genoa, Department of Health Sciences- DISSAL, Genoa, Italy.

Objectives: Vaccination against hepatitis B virus (HBV) is recommended in people living with HIV (PLHIV), although immune response rates are lower than in healthy individuals. We aimed at assessing response rates and predictors as well as persistence of seroprotection in a cohort of PLHIV with no serological evidence of current or previous HBV infection.

Methods: PLHIV followed at our site were retrospectively included if they started a primary HBV vaccination course (20 mcg dose three-doses schedule, alone or combined with inactivated hepatitis A virus) between 2007 and 2012. Read More

Comparative liver transcriptome analysis in ducklings infected with duck hepatitis A virus 3 (DHAV-3) at 12 and 48 hours post-infection through RNA-seq.

Vet Res 2018 Jun 20;49(1):52. Epub 2018 Jun 20.

Department of Preventive Veterinary Medicine, College of Veterinary Medicine, Northeast Agricultural University, Harbin, 150030, China.

Duck hepatitis A virus 3 (DHAV-3), the only member of the novel genus Avihepatovirus, in the family Picornaviridae, can cause significant economic losses for duck farms in China. Reports on the pathogenicity and the antiviral molecular mechanisms of the lethal DHAV-3 strain in ducklings are inadequate and remain poorly understood. We conducted global gene expression profiling and screened differentially expressed genes (DEG) of duckling liver tissues infected with lethal DHAV-3. Read More

Use of gender distribution in routine surveillance data to detect potential transmission of gastrointestinal infections among men who have sex with men in England.

Epidemiol Infect 2018 Jun 20:1-10. Epub 2018 Jun 20.

Field Epidemiology Service,Public Health England,London,UK.

Detecting gastrointestinal (GI) infection transmission among men who have sex with men (MSM) in England is complicated by a lack of routine sexual behavioural data. We investigated whether gender distributions might generate signals for increased transmission of GI pathogens among MSM. We examined the percentage male of laboratory-confirmed patient-episodes for patients with no known travel history for 10 GI infections of public health interest in England between 2003 and 2013, stratified by age and region.

Adherence with and completion of recommended hepatitis vaccination schedules among adults in the United States.

Vaccine 2018 Jun 13. Epub 2018 Jun 13.

Merck Sharp & Dohme Corp., a subsidiary of Merck & Co, Inc., Center for Observational and Real-World Evidence (CORE), Vaccines, Kenilworth, NJ, USA.

Introduction: Adult vaccination coverage rates in the US are well below national targets, leaving many adults at increased risk. Additionally, typical vaccination coverage calculations do not adequately approximate population immunity as they do not consider whether multidose vaccines were administered within the recommended schedules. As timely administration of each dose optimizes overall vaccine effectiveness, we sought to document adherence to and completion of the hepatitis A (HepA), hepatitis B (HepB), and combined hepatitis A and hepatitis B (HepA-HepB) multidose vaccine schedule in an insured adult population in the US.

Evidence of hepatitis A virus infection in the patients with acute encephalitis syndrome in Gorakhpur region, North India.

Acta Virol 2018 ;62(2):208-213

The etiological agent remained unidentified in a large number of patients hospitalized for acute encephalitis syndrome (AES) in 2008-2009 in Uttar Pradesh and Bihar, north India. All patients were found to present with fever and altered sensorium, while 28%, 19% and 13% showed hepatomegaly, splenomegaly and meningeal signs, respectively. Involvement mostly of children with abnormal hepatic features prompted us to undertake an exploratory study on viral hepatitis A to determine its association, if any, with hepatic derangements.

3Department of Pharmacotherapy, Meiji Pharmaceutical University, 2-522-1 Noshio, Kiyose, Tokyo, 204-8588 Japan.

Background: A causal relationship between acute pancreatitis and administration of glucocorticoids remains a matter of debate, since most of the reported cases were diagnosed with systemic vascular diseases (including systemic lupus erythematosus and polyarteritis nodosa) that may be responsible for the pancreatitis.

Case Presentation: We report a case of a 51-year-old woman who developed acute pancreatitis after receiving methylprednisolone pulse therapy for the treatment of fulminant autoimmune hepatitis (AIH). She was admitted to our hospital because of overt jaundice and back pain. Read More

On the Response of Nanoelectrode Impedance Spectroscopy Measures to Plant, Animal, and Human Viruses.

IEEE Trans Nanobioscience 2018 Apr;17(2):102-109

A simplified lumped geometrical and electrical model for the high-frequency impedance spectroscopy (HFIS) response of nanoelectrodes to capsids and full viruses is developed starting from atomistic descriptions, in order to test the theoretical response of a realistic HFIS CMOS biosensor platform to different viruses. Capacitance spectra are computed for plant (cowpea chlorotic mottle virus), animal (rabbit haemorrhagic disease virus), and human (hepatitis A virus) viruses. A few common features of the spectra are highlighted, and the role of virus charge, pH, and ionic strength on the expected signal is discussed. Read More

Adaptive Immune Responses in Hepatitis A Virus and Hepatitis E Virus Infections.

Cold Spring Harb Perspect Med 2018 May 29. Epub 2018 May 29.

Center for Vaccines and Immunity, The Research Institute at Nationwide Children's, Columbus, Ohio 43004.

Both hepatitis A virus (HAV) and hepatitis E virus (HEV) cause self-limited infections in humans that are preventable by vaccination. Progress in characterizing adaptive immune responses against these enteric hepatitis viruses, and how they contribute to resolution of infection or liver injury, has therefore remained largely frozen for the past two decades. How HAV and HEV infections are so effectively controlled by B- and T-cell immunity, and why they do not have the same propensity to persist as HBV and HCV infections, cannot yet be adequately explained.
