Association of physiological reserve measures with adverse outcomes following liver transplantation.

Background And Aim: The comparative utility of physiological reserve measures in predicting important clinical outcomes following liver transplantation (LT) requires further study. The aim of this work was therefore to compare the utility of physiological reserve measures in predicting early adverse clinical outcomes post-LT.

Methods: A single-center, retrospective cohort study of LT patients consecutively recruited between 1 January 2015, and 31 August 2020.

Hepatocellular carcinoma amongst Aboriginal and Torres Strait Islander peoples of Australia.

Background: Liver disease and hepatocellular carcinoma (HCC) are important contributors to the mortality gap between Indigenous and non-Indigenous Australians. However, there is a lack of population based high quality data assessing the differences in HCC epidemiology and outcomes according to Indigenous status. The aim of this study was therefore to perform a large epidemiological study of HCC investigating differences between Indigenous and non-Indigenous Australians with HCC.

The Chronic Liver Disease Nurse Role in Australia: Describing 10 Years of a New Role in Cirrhosis Management.

Cirrhosis of the liver is increasing, with growing patient numbers in hospital outpatient departments, as well as increasing admissions due to decompensated liver disease. Decompensated cirrhosis of the liver is a common and debilitating illness causing disability, readmissions to hospital, and decreased quality of life, and can lead to liver cancer. The advent of the chronic liver disease nurse (CLDN) position in our hospital in 2009 was the first role in Australia dedicated to providing care to patients with cirrhosis.

Stereotactic body radiation therapy for early hepatocellular carcinoma: a retrospective analysis of the South Australian experience.

Background: Stereotactic body radiation therapy (SBRT) is an emerging treatment option for liver tumours unsuitable for established curative treatment such as ablation or surgery. The aim of the study is to evaluate the efficacy and safety of SBRT in the treatment of small hepatocellular carcinoma (HCC) in South Australia.

Methods: From 2014 to 2018, 13 HCC patients were treated with SBRT.

High rates of indeterminate interferon-gamma release assays for the diagnosis of latent tuberculosis infection in liver transplantation candidates.

Background And Aims: Screening for latent tuberculosis infection (LTBI) is recommended prior to solid organ transplantation. Interferon-gamma release assays (IGRAs) are the most widely used test for LTBI screening; however, assessment of IGRA performance in patients with end-stage liver disease is limited. The purpose of this study was to evaluate the prevalence and predictors of indeterminate (INDT) IGRA results in liver transplantation candidates.

Efficacy of High-Dose, Rapid, Hepatitis A and B Vaccination Schedules in Patients With Cirrhosis.

Patients with cirrhosis have increased morbidity from hepatitis A virus (HAV) and hepatitis B virus (HBV) infections, and vaccination against these infections is an important standard of care. However, vaccination in patients with cirrhosis is hindered by immune dysfunction and there is limited high-quality literature available. The aim of this work therefore was to compare immune responses of standard dose (SD) with high-dose accelerated (HDA) vaccination in cirrhotic patients.

The Interferon-induced Transmembrane Proteins, IFITM1, IFITM2, and IFITM3 Inhibit Hepatitis C Virus Entry.

The interferon-induced transmembrane (IFITM) family of proteins have recently been identified as important host effector molecules of the type I interferon response against viruses. IFITM1 has been identified as a potent antiviral effector against hepatitis C virus (HCV), whereas the related family members IFITM2 and IFITM3 have been described to have antiviral effects against a broad range of RNA viruses. Here, we demonstrate that IFITM2 and IFITM3 play an integral role in the interferon response against HCV and act at the level of late entry stages of HCV infection.

Generation of a chimeric hepatitis C replicon encoding a genotype-6a NS3 protease and assessment of boceprevir (SCH503034) sensitivity and drug-associated mutations.

Background: Genotype (gt)6 HCV is common amongst HCV-positive populations of the Asia-Pacific region but cell culture models for this gt have only recently been developed. Boceprevir (SCH503034) is a clinically available inhibitor of the HCV NS3 protein. We investigated the efficacy of boceprevir for inhibiting replication of a chimeric gt1b replicon encoding a gt6a NS3 protease and defined the development of mutations in the protease when boceprevir treatment was applied.

Signal transducer and activator of transcription 3 is a proviral host factor for hepatitis C virus.

Unlabelled: Host factors play an important role in all facets of the hepatitis C virus (HCV) life cycle and one such host factor is signal transducer and activator of transcription 3 (STAT3). The HCV core protein has been shown to directly interact with and activate STAT3, while oxidative stress generated during HCV replication in a replicon-based model also induced STAT3 activation. However, despite these findings the precise role of STAT3 in the HCV life cycle remains unknown.

Viperin is induced following dengue virus type-2 (DENV-2) infection and has anti-viral actions requiring the C-terminal end of viperin.

The host protein viperin is an interferon stimulated gene (ISG) that is up-regulated during a number of viral infections. In this study we have shown that dengue virus type-2 (DENV-2) infection significantly induced viperin, co-incident with production of viral RNA and via a mechanism requiring retinoic acid-inducible gene I (RIG-I). Viperin did not inhibit DENV-2 entry but DENV-2 RNA and infectious virus release was inhibited in viperin expressing cells.
