Hepatitis D virus (HDV) infection plays an important role in liver diseases. However, the molecular epidemiology and impact of HDV infection in chronic hepatitis B (CHB) remain uncertain in Vietnam. This cross-sectional study aimed to investigate the prevalence and genotype distribution of HDV among HBsAg-positive patients in Central Vietnam. 250 CHB patients were tested for HDV using newly established HDV-specific RT-PCR techniques. HDV genotypes were determined by direct sequencing. Of the 250 patients 25 (10%) had detectable copies of HDV viral RNA...

Hepatitis B virus (HBV) is one of the major causes of viral hepatitis worldwide. Despite the prevalence of HBV infection in Egypt, few studies have focused on sub-genotyping of the virus. Moreover, no studies are available regarding the mutational analysis of the preS1/preS2 region of the viral genome, or its impact on hepatocellular carcinoma (HCC) development in Egypt. In this study, we have analyzed the sub-genotypes and incidence of mutations in the preS1/preS2 region of HBV present in HBV-infected patients, from Mansoura city (located in the centre of Nile Delta region of Egypt), via partial sequencing of this specific region...

Vitamin D deficiency was common among patients with chronic hepatitis C (CHC) and had negative influence on treatment outcome. Correction of vitamin D deficiency improved treatment response. Interferon gamma-induced protein 10 (IP-10) and enzyme dipeptidyl peptidase-4 (DPP IV) involved in inflammatory responses in CHC. Their higher levels at pretreatment of CHC could predict poorer responses. Vitamin D suppressed expression of IP-10 from monocytes in vitro. In CHC patients, DPP IV involved in IP-10 regulation...

BACKGROUND: Roughly 15 million people worldwide have hepatitis delta, the most severe form of chronic viral hepatitis that often leads to cirrhosis and liver cancer. Injection drug users (IDUs) are the largest HDV reservoir. Their resurgence in North America and Europe may represent a new opportunity for HDV widespread. METHODS: We examined all consecutive active IDUs seen for the first time and enrolled in detoxification programs at two clinics in Spain during two periods (1993-1996 and 2011-2014, respectively)...

INTRODUCTION: Hepatitis D virus (HDV) infection is a serious health problem leading to cirrhosis and hepatocellular carcinoma (HCC). Despite evidence that zoonotic infections are associated with end-stage liver disease, brucellosis in patients with delta hepatitis related to liver disease has not been well characterized. So, we examined this relationship using recent hospital-based data. MATERIAL AND METHODS: We analyzed data from 96 delta hepatitis patients (mean age: 52...

Hepatitis delta virus (HDV) is a minimalistic satellite virus of hepatitis B virus (HBV). HBV/HDV co-infection, i.e. "hepatitis D", is the most severe form of viral hepatitis. No effective therapy for HDV infection is available partly due to the fact that HDV is a highly host-dependent virus devoid of any potentially drugable enzyme encoded in its small genome. In this study we present a semi-automated method to evaluate HDV infection and replication under the influence of different drugs. We utilized a Huh-7/hNTCP cell culture based system in a 96-well plate format, an automated microscope and image acquisition as well as analysis with the CellProfiler software to quantify the impact of these drugs on HDV infection...

We analyzed changes in hepatitis B virus and hepatitis delta virus (HDV) viral loads (VL) during tenofovir-containing antiretroviral therapy among patients with a replicating HDV infection in the Swiss HIV Cohort Study. Only 28.6% experienced a ≥2.0 log reduction in HDV RNA, and 14.3% had undetectable HDV VL within 5 years.

Newcastle disease virus (NDV), strain R2B is a mesogenic vaccine strain used for booster vaccination in chickens against Newcastle disease in India and many south East Asian countries. A full-length cDNA clone of the virus was generated by ligating eight overlapping fragments generated by reverse transcription polymerase chain reaction having unique restriction enzyme sites within them. This full-length cDNA clone was flanked by hammerhead ribozyme and hepatitis delta virus ribozyme sequences. Defined genetic markers were introduced into the NDV genome to differentiate the rescued virus from the parent virus...

BACKGROUND AND AIMS: HCV infection is a leading risk factor of hepatocellular carcinoma (HCC). However, even after viral clearance, HCC risk remains elevated. HCV perturbs host cell signalling to maintain infection, and derailed signalling circuitry is a key driver of carcinogenesis. Since protein phosphatases are regulators of signalling events, we aimed to identify phosphatases that respond to HCV infection with relevance for hepatocarcinogenesis. METHODS: We assessed mRNA and microRNA (miRNA) expression profiles in primary human hepatocytes, liver biopsies and resections of patients with HCC, and analysed microarray and RNA-seq data from paired liver biopsies of patients with HCC...

HDV prevalence must not be disregarded, as the virus is associated with a higher severity of hepatic disease. All HBV carriers should be tested for HDV as well, at least once during the disease history, and in case of worsening of a chronic HBV hepatitis. Diagnosis should rely on anti-HDV antibody testing, and confirmed by HDV RNA detection and quantification by RT-qPCR. The only treatment available is pegylated alpha interferon. Optimal duration of treatment has not yet been proven, and relapses are common...

Viral liver diseases are frequent comorbidities and major contributors to death in HIV-positive individuals on antiretroviral therapy. Although cure of hepatitis C and control of hepatitis B with antivirals avert liver disease progression in most HIV-coinfected patients, the lack of satisfactory treatment for hepatitis delta virus (HDV) infection remains a major threat for developing cirrhosis and liver cancer in this population. In the European Union (EU) and North America, sexual contact has replaced injection drug use that has been the major transmission route for HDV in HIV-positive persons...

Tomato black ring virus (TBRV, genus Nepovirus) infects a wide range of economically important plants such as tomato, potato, tobacco and cucumber. Here, a successful construction of infectious full-length cDNA clones of the TBRV genomic RNAs (RNA1 and RNA2) is reported for the first time. The engineered constructs consisting of PCR-amplified DNAs were cloned into binary vector pJL89 immediately downstream of a double cauliflower mosaic virus (CaMV) 35S promoter, and upstream of the hepatitis delta virus (HDV) ribozyme and nopaline synthase terminator (NOS)...
