$569,219.00
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.
A Study Of The Relationship Between Vitamin D Status And The Severity And Outcomes Of Chronic Non-cholestatic Liver Disease

Summary
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. This research will further investigate the relationship of vitamin D deficiency to liver disease caused by the common conditions hepatitis B and C and non-alcoholic fatty liver disease and th ....Vitamin D deficiency is associated with common and severe conditions such as cancer, cardiovascular disease, autoimmune disease and diabetes.

Epithelial cell surface mucins are large complex proteins found on the surface of all mucosal epithelial tissues, for example in the respiratory, gastrointestinal, reproductive and urinary tracts. Most bacterial and viral pathogens enter the body via mucosal tissues. We have recently demonstrated that mucin proteins are a vital component of initial defence against mucosal pathogens. Defects in these proteins probably predispose individuals to common chronic infective and inflammatory diseases.

Most bacterial and viral pathogens enter the body via mucosal tissues. We have recently demonstrated that mucin proteins are a vital component of initial defence against mucosal pathogens. Defects in these proteins probably predispose individuals to common chronic infective and inflammatory diseases. The proposed research aims to explore the mechanims by which mucins protect from infection, with a focus on the gastrointestinal tract. Gastrointestinal infections remain one of the major causes of mortality in children in undeveloped countries. We believe that these proteins are a critical hereto unrecognised element of immunity and that the proposed studies will have broad significance for treatment and prevention of infection. Additionally, understanding the function of mucins could lead to the development of new drugs to treat epithelial inflammation such as that seen in inflammatory bowel diseases and respiratory diseases such as asthma and cystic fibrosis.Read moreRead less
Population-level Epidemiological Trends In Hepatocellular Carcinoma In Queensland 1996 - 2010.

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.

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 trends.Read moreRead less
Hookworm Therapy In Coeliac Disease (CeD), Phase 1b

National Health and Medical Research Council
Funding Amount
$865,002.00
Summary
Parasitic worms have an amazing ability to manipulate the immune system, and our research group recently discovered how they may hold the key for treating inflammatory diseases such as Coeliac Disease. The aim of my research is to further develop this novel therapy in a clinical trial and study the mechanism of how worms control the immune response, including identifying the molecules that the worm produces that could be produced as a pill-based medication for treating coeliac disease.
Determinants Of Sustained Virological Response After Discontinuation Of Long-term Nucleoside Analogue Therapy In Chronic Hepatitis B Patients
Funder
National Health and Medical Research Council
Funding Amount
$976,778.00
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.
Studies Of The Role Of The Hepatocyte In The Response To HCV Infection

Funding Amount

Summary
Infection with hepatitis C (HCV) affects 120 million individuals worldwide, and over 200,000 in Australia. HCV-related liver disease is the most common indication for liver transplantation in Australia and rates of HCV-related liver failure and hepatocellular cancer are predicted to increase as the HCV population ages. A new test for the IL28B gene, has shown to be the strongest predictor of cure after treatment. The mechanism of this association is unknown and is the subject of this grant.

Summary
About 3% of the world population is currently infected with hepatitis C virus (HCV). Most have chronic infection with a high risk for progressive liver fibrosis and subsequent liver cirrhosis and hepatocellular carcinoma. We have recently demonstrated genetic variants of the IL28B gene predict viral clearance with and without treatment after HCV infection.

Understanding The Role Of Infectious Agents As A Trigger Of Crohns Disease In Children With Early Onset Disease

Funding Amount
$570,876.00
Summary
Crohn's disease is a major cause of illness throughout the world. There is no cure and current therapies carry substantial risks. An infectious agent has been suggested as the trigger for disease but research has been inconclusive. Our study focuses on the characterisation of a novel virus we have identified that may trigger Crohn's disease in children at disease onset.
The Role Of Endocannabinoids In Chronic Hepatitis C

Funding Amount

Summary
Hormones related to cannabis help to regulate fat stores in the human body. CB1 antagonists are a new class of drugs that block these hormones and are being tested for the treatment of obesity and fatty liver. We discovered that Hepatitis C makes the liver more sensitive to these hormones, helping the hepatitis C virus to replicate. This project will determine the mechanisms by which CB1 antagonists prevent hepatitis C virus replication and their potential as a novel therapy for this disease.
