Hepatits B Traveller's Guide
Hepatitis B is a worldwide health problem with 350 million people thought to be infected. In high-risk countries, 8% or more of the population can be infected. High risk areas include sub-Saharan Africa, most of Asia and parts of the Amazon region, but care is advised in all countries. Ref. Source 7
Drug abuse fuels steep rise in hepatitis B in Appalachia, study shows
Cases of hepatitis B, often spurred by the use of drugs injected into the body, spiked in Kentucky, Tennessee and West Virginia, according to a new study released Thursday by the Centers for Disease Control. It signals a threat to other parts of the country where the use of illegal drugs injected into the body, such as heroin, has risen. Ref. USAToday.
Antiviral therapy prolongs survival in immune tolerant hepatitis B patients
A new study demonstrates that the use of antiviral therapy for patients in the immune tolerant phase of hepatitis B (HBV) prolongs overall survival and reduces the risk of the most common form of liver cancer (Hepatocellular Carcinoma, HCC) and scarring of the liver (Cirrhosis). Ref. Source 6d.
Treatment for chronic hepatitis B linked to increased rates of colorectal and cervical cancer
A new study demonstrates a potential link between treatment of long-term oral nucleos(T)ide analogues and an increased risk of colorectal (P=0.029) and cervical (P=0.049) cancer in patients with chronic hepatitis B virus (HBV). Ref. Source 9s.
'Virus-cracking' molecules advance fight against hepatitis B. Researchers have found that certain molecules -- currently under clinical trial -- are able to 'crack' the protective shell of the hepatitis B virus, suggesting it may be possible to attack the virus after its already taken hold in the body. There is currently no cure for the virus, which can cause liver failure and cancer. Source 4r.
