Lookback was initiated upon notification of an acute HBV infection in a repeat Irish donor, 108 days post-donation. The donation screened non-reactive by individual-donation nucleic acid testing (ID-NAT) using the Procleix Ultrio Elite multiplex assay and again when the archived sample was retested, but the discriminatory assay for HBV was reactive. The immunocompromised recipient of the implicated red cell component was tested 110 days post-transfusion, revealing a HBV DNA viral load of 470 IU/ml. Genotype C2 sequences identical across two regions of the HBV genome were found in samples from the donor and recipient...

As current treatment options almost never achieve eradication of hepatitis B virus (HBV), the most realistic goal for HBV treatment is persistent inhibition of viral replication and ALT normalization. Thus, the decision to start treatment should be based on careful patient selection and individualized decisions. Treatment is generally indicated in chronic hepatitis B patients with HBV DNA >2000 IU/mL, elevated ALT and/or at least moderate histological lesions, while all patients with cirrhosis and detectable HBV DNA should be treated...

The outbreak of the Zika virus (ZIKV) has been associated with increased incidence of congenital malformations. Although recent efforts have focused on vaccine development, treatments for infected individuals are needed urgently. Sofosbuvir (SOF), an FDA-approved nucleotide analog inhibitor of the Hepatitis C (HCV) RNA-dependent RNA polymerase (RdRp) was recently shown to be protective against ZIKV both in vitro and in vivo. Here, we show that SOF protected human neural progenitor cells (NPC) and 3D neurospheres from ZIKV infection-mediated cell death and importantly restored the antiviral immune response in NPCs...

BACKGROUND & AIMS: GS-9620, an oral agonist of toll-like receptor 7 (TLR7), is in clinical development for the treatment of chronic hepatitis B (CHB). GS-9620 was previously shown to induced prolonged suppression of serum viral DNA and antigens in the chimpanzee and woodchuck models of CHB. Here we investigated the immunomodulatory mechanisms underlying these antiviral effects. METHODS: Archived liver biopsies and paired PBMC samples from a previous chimpanzee study were analyzed by RNA-Seq, qRT-PCR, immunohistochemistry (IHC) and in situ hybridization (ISH)...

Evidence documenting the global burden of disease from viral hepatitis was essential for the World Health Assembly to endorse the first Global Health Sector Strategy (GHSS) on viral hepatitis in May 2016. The GHSS on viral hepatitis proposes to eliminate viral hepatitis as a public health threat by 2030. The GHSS on viral hepatitis is in line with targets for HIV infection and tuberculosis as part of the Sustainable Development Goals. As coordination between hepatitis and HIV programs aims to optimize the use of resources, guidance is also needed to align the strategic information components of the 2 programs...

BACKGROUND: Hepatitis B infection caused by the hepatitis B virus is one of the most serious viral infections and a global health problem. In the transmission of hepatitis B infection, three different phases, i.e. acute infected, chronically infected, and carrier individuals, play important roles. Carrier individuals are especially significant, because they do not exhibit any symptoms and are able to transmit the infection. Here we assessed the transmissibility associated with different infection stages of hepatitis B and generated an epidemic model...

Mongolia is known for its high endemicity for viral hepatitis. Previous studies report that the seroprevalence of hepatitis B virus (HBV) is 11.8% (178/1,512) among the unvaccinated population in 13 provinces and Ulaanbaatar city. The serosurvey of adults (>20 years of age) conducted during 2013 among persons in four provinces and in Ulaanbaatar showed that the overall prevalence of hepatitis B surface antigen (HBsAg) positivity was 10.6%. The overall prevalence of anti-hepatitis C virus (HCV) and HCV ribonucleic acid among 1,512 apparently healthy subjects was 15...

Hepatitis B virus (HBV) can manipulate the miRNA regulatory networks in infected cells to create a permissive environment for viral replication, cellular injury, disease onset and its progression. The aim of the present study was to understand the miRNA networks and their target genes in the liver of hepatitis B patients involved in HBV replication, liver injury and liver fibrosis. We investigated differentially expressed miRNAs by microarray in the liver biopsy samples from different stages of HBV infection and liver disease [immune tolerant (IT; n= 8); acute viral hepatitis (AVH; n=8); no fibrosis (n=16); early (F1+F2) (n=19) or late fibrosis (F3+F4) (n=14) and healthy controls (n=7)]...

Hepatitis C virus (HCV) infection causes acute and chronic liver disease and may lead to cirrhosis, liver failure or hepatocellular carcinoma. The behavior of illicit drug users (DUs) typically exposes them to risks of viral infection. In the Brazilian Amazon region, a number of studies have identified high rates of drug use among adolescents, and a high prevalence of HBV infection in DUs, disseminated by sexual and parenteral activities. However, the epidemiological scenario of HCV infection in the region is still poorly understood...

BACKGROUND: Infection with the hepatitis E virus (HEV) can cause acute hepatitis in endemic areas in immune-competent hosts, as well as chronic infection in immune-compromised subjects in non-endemic areas. Most studies assessing HEV infection in HIV-infected populations have been performed in developed countries that are usually affected by HEV genotype 3. The objective of this study is to measure the prevalence and risk of acquiring HEV among HIV-infected individuals in Nepal. METHODS: We prospectively evaluated 459 Human Immunodeficiency Virus (HIV)-positive individuals from Nepal, an endemic country for HEV, for seroprevalence of HEV and assessed risk factors associated with HEV infection...
