Hepatitis associated anti-tuberculous treatment (HATT) has been a main obstacle in managing patients co-infected with Mycobacterium tuberculosis and hepatitis B virus (HBV). Therefore, we evaluated the factors related to the severity of adverse effects during HATT, especially those associated with liver failure. A retrospective study was carried out at Tongji Hospital from 2007 to 2012. Increases in serum transaminase levels of >3, 5, and 10 times the upper limit of normal (ULN) were used to define liver damage as mild, moderate, and severe, respectively...

Toxic shock syndrome (TSS) is caused by staphylococcal and streptococcal superantigens (SAgs) that provoke a swift hyperinflammatory response typified by a cytokine storm. The precipitous decline in the host's clinical status and the lack of targeted therapies for TSS emphasize the need to identify key players of the storm's initial wave. Using a humanized mouse model of TSS and human cells, we herein demonstrate that SAgs elicit in vitro and in vivo IL-17A responses within hours. SAg-triggered human IL-17A production was characterized by remarkably high mRNA stability for this cytokine...

Hepatitis B reactivation associated with immune suppressive and biological therapies is emerging to be an important cause of morbidity and mortality in patients with current or prior exposure to hepatitis B virus infection. The population at risk for HBV reactivation includes those who are either currently infected with HBV or have past exposure to HBV. Since curative and eradicative therapy for HBV is not currently available, there is a large reservoir of individuals at risk for HBV reactivation in the general population...

Evidence exists that dairy cows experience inflammatory-like phenomena in the transition period. Rumen health and alterations in metabolic processes and gene networks in the liver as the central metabolic organ might be key factors for cows' health and productivity in early lactation. This study made use of an animal model to generate experimental groups with different manifestations of postpartal fat mobilization and ketogenesis. In total, 60 German Holstein cows were allocated 6 wk antepartum to 3 high-body condition score (BCS) groups (BCS 3...

Background/Aims: We aimed to clarify the association of HBsAg/HBcAg with the disease status and treatment response in patients with chronic hepatitis B (CHB). Methods: We investigated 171 biopsy-proven entecavir-treated CHB patients (109 HBeAg-positive, 62 HBeAg-negative). HBcAg expression was positive when ≥10% of hepatocytes stained, and classified into nuclear, mixed, and cytoplasmic patterns. HBsAg expressions were intracytoplasmic (diffuse, globular, and submembranous) and membranous...

BACKGROUND: Chronic hepatitis B is a common, progressive disease, particularly when viral replication is detected. Oral antivirals can suppress viral replication and prevent or delay the development of cirrhosis and liver-related complications. The treatments of chronic hepatitis B cannot totally cure the disease but can prevent its progression to hepatocellular carcinoma, decreasing the levels of both morbidity and mortality. To date, there are several therapies indicated by the international guidelines as first-line treatments for the management of hepatitis B; two of the most effective are those based on either tenofovir or entecavir...

: There is an increased awareness of hepatitis B (HBV) reactivation in chronic hepatitis C (CHC) patients coinfected with HBV treated with pan-oral direct-acting antivirals (DAAs). We performed a systematic review and meta-analysis to compare the rate of HBV reactivation in CHC patients coinfected with overt HBV (hepatitis B surface antigen [HBsAg] positive) and occult HBV (HBsAg negative with positive HBV DNA) infection separately, treated with interferon (IFN)-based therapy to those with pan-oral DAAs...

Few reports are available on HCV molecular epidemiology among IDUs in Eastern Europe, and none in Montenegro. The aim of this study was to investigate the HCV genotype distribution in Montenegro among IDUs and to perform Bayesian and evolutionary analysis of the most prevalent HCV genotype circulating in this population. Sixty-four HCV-positive IDUs in Montenegro were enrolled between 2013 and 2014, and the NS5B gene was sequenced. The Bayesian analysis showed that the most prevalent subtype was HCV-3a. Phylogenetic data showed that HCV-3a reached Montenegro in the late 1990s, causing an epidemic that exponentially grew between the 1995 and 2005...

The primary goal of therapy for chronic hepatitis B (CHB) is to prevent liver disease progression. Hepatitis B surface antigen (HBsAg) seroclearance or seroconversion is regarded as an optimal endpoint to discontinue treatment. However, HBsAg seroclearance occurs very rarely with nucleos(t)ide analog (NUC) treatment, and long-term, almost indefinite, NUC treatment is required for the majority of patients. In patients with drug-resistant hepatitis B virus (HBV), a combination of tenofovir disoproxil fumarate (TDF) and entecavir (ETV), which is currently regarded as the strongest combination therapy against HBV, would be potentially safe to prevent the emergence of additional HBV resistance mutations...

California sea lion adenovirus 1 (CSLAdV-1) has been associated with hepatitis and enteritis in several wild and captive populations of diverse pinniped species. Currently available tests have been limited to pan-adenoviral polymerase chain reaction (PCR) followed by sequencing. We present the development of a quantitative probe-hybridization PCR (qPCR) assay for rapid, sensitive, and specific detection of this virus in California sea lions ( Zalophus californianus) and other pinnipeds. This assay did not amplify other mammalian adenoviruses and is able to detect consistently down to 10 viral copies per well...

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer related mortality worldwide. HCC incidences have increased worldwide though more prevalent in Asia and Africa. Hepatitis B virus and hepatitis C virus infections are mostly responsible of increased number of HCC cases. Biomarkers can help early detection and improve treatment regimen in patients as advanced stage is chemo-refractive with limited treatment options. Potential of proteomics in finding new biomarkers for early detection has been explored more recently...

In patients with lymphoma the detection of positive hepatitis B or C viruses (HBV and HCV) serology involves crucial therapeutic consequences. In HBV-infected patients the serological profile of active (HBsAg-positive) or resolved (HBsAg-negative/anti-HBcAb-positive) infection is associated to differential risk of viral reactivation during rituximab-based therapy and require appropriate strategies of monitoring and of antiviral prophylaxis. In HCV-associated NHL patients consolidated data demonstrated that interferon (IFN)-based antiviral therapy (AT) is able to induce lymphoma regression strictly related to viral eradication, while preliminary data of the new direct-acting antivirals (DAAs) are very promising...

: Hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) are difficult to manage with very poor survival and due to universal recurrence after liver transplantation, they have been excluded from indication. Conformer radiation therapy (RT) has been shown to be effective in the treatment of HCC but only few trials have been reported as bridge to liver transplantation (LT) in HCC with PVTT. The purpose of our study was to evaluate the possibility of applying living donor liver transplantation (LDLT) following successful downstaging using RT in advanced HCC with PVTT...
