Approval from the Alfred Hospital Ethics Committee will be obtained and subjects will be recruited via the Alfred Hospital's Hepatitis Clinics. Informed consent for the study will be obtained after its purpose is explained verbally and via a plain English statement. Informed consent will also include consent for liver biopsies. Initially, a pilot study will be undertaken in which only one subject will be recruited to both the experimental and control arm of the study. Once the results from this pilot study have been analysed the study will be expanded to encompass a greater number of individuals.
