The unique hepatitis B virus genotype C4 circulates among Indigenous Australians. The aim of this work is to describe the process of establishing this cohort and review the first 6 years of available data in an effort to understand the real-world clinical care and natural history of this subgenotype.
We followed a longitudinal cohort of Indigenous Australians from the Northern Territory of Australia with established subgenotype C4 infections. We assigned phases of disease according to Gastroenterological Society of Australia and Asian Pacific Association for the Study of the Liver criteria using clinical and laboratory information that had been collected for clinical management. In this relatively young cohort median age

The team showed in its publication, that T-cell therapy can provide a permanent cure. Up to now it has not been possible to fully control the virus. Their findings have now been published in the Journal of Clinical Investigation. Infections with the hepatitis B virus HBV are a global health problem. According to the World Health Organisation WHO , more than million people worldwide are chronically infected with the virus.
Vaccination prevents new HBV infections, but for people who are chronic carriers of the virus, a cure has not yet been found. Available drugs only prevent the virus from continuing to replicate in liver cells, but they cannot eliminate it. In the long term, this can lead to complications such as liver cancer or liver cirrhosis, whereby functional liver tissue is replaced by fibrous connective tissue.
We have now been able to show that T-cell therapy exploiting new technologies presents an encouraging solution for the treatment of chronic HBV infection and liver cancer that is triggered by the virus. That is because these ‘living drugs’ are the most potent therapy we have at our disposal at present,” explains Prof.
Hepatitis B: New therapeutic approach may help to cure chronic hepatitis B infection
However, the specific effects of chronic HBV infection on life expectancy have not been adequately studied. Taiwan is endemic for HBV infection, and thus provides sufficient information for such estimates. An abridged life table was used to calculate carrier life expectancy.

Once in the liver, the virus reproduces and releases large numbers of new viruses into the bloodstream.
To combat the disease, the body has several defenses. White blood cells, which protect the body from infections, attack and destroy the infected liver cells. The body also produces antibodies which circulate in the blood to destroy the virus and protect against future infections of hepatitis B. During the infection and recovery process, the liver may not function normally causing illness that affects the entire body.
