Summary
The hepatitis B virus causes liver cirrhosis and liver cancer. There is no cure for hepatitis B. However, a small number of patients can naturally rid themselves of the virus. We have identified 14 of these individuals and discovered that they have a unique immune response that is responsible for these “natural” cures. We plan to characterise this immune response and turn it into a therapeutic vaccine which can be used to cure patients who are still chronically infected.
ANTIVIRAL DRUG RESISTANT HBV: PATHOGENIC AND ONCOGENIC SIGNIFICANCE OF THE ALTERED VIRAL ENVELOPE

Summary
We aim to investigate the consequences of long-term therapy for hepatitis B on liver cancer progression. We propose that antiviral therapy is associated with persistent expression and accumulation of potentially oncogenic surface proteins in the liver. This can dramatically alter the viral lifecycle, particularly the HBsAg secretion pathway, which can cause serious effects in the host hepatocyte biology, including promoting pathways to tumour formation.

Summary
The overall aim of this proposal is to tackle unmet challenges in liver disease research. This will be achieved through (a) Population level programs to deliver new treatments for patients with hepatitis C; (b) Developing integrated care models to treat hepatitis B; (c) Developing population-level programs for liver cancer control; and (d) Identification of patients at risk of severe liver disease through understanding the genetic basis of disease progression.

Vitamin D deficiency is associated with common and severe conditions such as cancer, cardiovascular disease, autoimmune disease and diabetes. Recent studies suggest that vitamin D deficiency also worsens the severity and prognosis of chronic liver disease and that vitamin D replacement may improve outcomes.

Determinants Of Sustained Virological Response After Discontinuation Of Long-term Nucleoside Analogue Therapy In Chronic Hepatitis B Patients

Summary
Guidelines currently recommend lifelong treatment for patients with chronic hepatitis B, with associated cost and risks of drug resistance and side effects. It has recently been suggested that up to 50% of patients may safely and successfully stop drug after long-term treatment. Our project will identify which patients can safely stop treatment, by performing detailed studies of the human immune system and the hepatitis B virus. This will be an important advance for patient care.

Presently, liver disease from chronic hepatitis C and obesity represents a major health problem. Overall, approximately 50% of Australians with chronic hepatitis C are obese and these patients are at significantly increased risk of rapidly progressing to liver failure. It is now recognized that fat derived factors play an important role in regulating inflammatory responses.

Summary
Incidence and mortality of hepatocellular carcinoma (HCC, the most common form of liver cancer) is increasing in Australia, driven by viral hepatitis infections. Disease burden is not defined in Queensland, particularly for Indigenous, migrant and regional and remote communities. Such factors may influence risk of viral hepatitis, access to treatment, and incidence and survival of HCC. Defining disease burdens will enable clinical programs targeted at groups most at risk in order to impact HCC t ....Incidence and mortality of hepatocellular carcinoma (HCC, the most common form of liver cancer) is increasing in Australia, driven by viral hepatitis infections.

Virological Determinants Of Drug Resistance In Real-world Patients With Chronic HCV Infection

Summary
New treatments for hepatitis C virus (HCV) infection are emerging. These drugs directly target key events in the viral life cycle. While these drugs are effective, the ability of HCV to mutate means that drug resistance can arise, leading to treatment failure. This is most likely in patients who do not respond to interferon-based therapy. This proposal will use new, highly sensitive sequencing approaches to identify the viral mutations and evolutionary pathways that lead to drug resistance.
Hepatitis C affects a quarter of a million Australians, causing insidious but progressive liver disease which culminates in liver failure or cancer. There is no vaccine and prevention programs have limited effectiveness, but new antiviral therapies now offer high rates of cure. This Program will evaluate strategies to improve the health of those affected and prevent new infections by better understanding of the virus and the body’s immune response, including scarring and liver cancer formation.
