Summary
Hepatitis C therapy in the future is likely to involve the use of Directly Acting Antivirals, which offer a better chance of treatment success and shorter treatment courses. The downside to these new agents is the possible development of drug resistance. Studies suggest that drug resistant strains may already exist in some individuals prior to treatment. This study plans to use sensitive methods to examine how common drug resistant strains are in untreated individuals with acute hepatitis C.
The renewal of my Practitioner Fellowship will continue to facilitate an expanding program of epidemiological and clinical research in viral hepatitis, with a primary focus on hepatitis C. New directions will include development of international clinical cohort and trials networks, particularly to characterise the natural history of early hepatitis C infection and evaluate hepatitis C therapuetic strategies for injecting drug users.
I am infectious disease physician undertaking research on natural history and therapeutic strategies in viral hepatitis, including acute hepatitis C, chronic hepatitis C and chronic hepatitis B. The hepatitis C therapeutic research has a particular focus
Fine Positioning And Effector Function Of T Cells Recruited To The HCV Infected Liver

Summary
The majority of patients who become infected with hepatitis C virus (HCV) are unable to mount an effective immune response and clear the virus and therefore develop lifelong (chronic) infection. The persistence of virus in the liver of patients with chronic infection results in the recruitment of significant numbers of immune cells, notably T cells, from the bloodstream into the liver where they are involved in both viral control (but not viral clearance) and liver injury. The level of tissue in ....The majority of patients who become infected with hepatitis C virus (HCV) are unable to mount an effective immune response and clear the virus and therefore develop lifelong (chronic) infection. The persistence of virus in the liver of patients with chronic infection results in the recruitment of significant numbers of immune cells, notably T cells, from the bloodstream into the liver where they are involved in both viral control (but not viral clearance) and liver injury. The level of tissue injury observed and the speed of disease progression may be linked to the type of T cells recruited, their function, and their position in the liver. The aims of this project are to determine the factors involved in the fine positioning of T cells in the liver and establish a relationship between T cell recruitment, function, and progression of HCV disease in the liver.Read moreRead less
The development of vaccines and better treatments for HIV-AIDS and Hepatitis C are urgent global health priorities. This Program will undertake studies to better understand effective immunity against HIV and hepatitis C, allowing the rational design and testing of novel vaccines and treatments. The Program brings together a team of researchers with skills in basic virology and immunology with those providing expertise in translating findings in the laboratory into human clinical trials.
Implementation Of Highly Effective Therapy For Hepatitis C

Summary
Hepatitis C is a major public health issue in Australia, and globally, with escalating liver disease burden. Highly effective interferon-free HCV regimens will be available from 2016 and have the potential to provide one of the greatest advances in clinical medicine in recent decades. Development of implementation strategies for new HCV therapies, particularly for highly marginalised populations including people who inject drugs and prisoners, is crucial to provide broad public health impact.
Hepatitis C infection can be cured by using highly effective, simple, recently developed medications. This fellowship will explore new modes of delivering hepatitis C treatment outside of traditional hospital clinics. It will also explore the potential for successful treatment to prevent transmission of the hepatitis C. The fellowship will involve the first clinical trial of its type, along with modelling the benefits and cost-effectiveness of treatment and prevention.
Surveillance And Treatment Of Prisoners With Hepatitis C (SToP-C)

Summary
SToP-C will investigate whether a significant reduction in hepatitis C infection in NSW prisons is possible with a “treatment as prevention” strategy. It will treat prisoners for hep C infection both to improve their own health and to make onward transmission to others less likely. There is currently a lack of available effective strategies; however through delivery of simple, effective new therapies this world-first trial offers significant opportunities to reduce the burden of liver disease.

Summary
HIV exists as multiple subtypes. The most commonly studied is type B (B-HIV). B-HIV is common in developed countries, but accounts for only a small fraction of HIV infections worldwide. Type C HIV (C-HIV) in Africa and Asia accounts for the majority of infections worldwide, yet very little is known about how C-HIV causes AIDS. We aim to understand how C-HIV causes AIDS. This is critical for development of drugs and vaccines specifically designed for those who are most urgently need.
