Hepatitis C: Teenager Jazzy's Story

NHS Choices: Teenager Jazzy was born with hepatitis C. This is her video diary about living with the condition.

@napernurse: Fortunate to live in UK where extensive med/psych prescriptions for HepatitisC covered by NHS. If liver transplant needed, that is covered too!

Hepatitis delta virus

From a recent review in The Lancet:

Hepatitis delta virus (HDV) is a small, defective RNA virus that can infect only individuals who have hepatitis B virus (HBV). More than 15 million people are co-infected worldwide.

There are 8 genotypes of HDV. The hepatitis D virion is composed of a coat of HBV envelope proteins surrounding the nucleocapsid.

The nucleocapsid consists of:

- a single-stranded, circular RNA genome
- delta antigen, viral protein

HDV suppresses HBV replication but also causes severe liver disease with rapid progression to cirrhosis and hepatic decompensation (liver failure).

The range of clinical presentation is wide, varying from mild disease to fulminant liver failure.

Treatment of HDV is with pegylated interferon alfa; however, response rates are poor.

Better understanding of the molecular structure of HDV may lead to new therapeutic targets for this most severe form of chronic viral hepatitis.

New hepatitis C treatment: 2 new medications may increase success rate to 70%

Mayo Clinic: Four million people in the U.S., 100 million worldwide, are infected with Hepatitis C. It's a virus you can get from blood transfusions given before 1990, shared needles, unclean tattoo needles and sometimes sex.

In many cases it leads to cirrhosis of the liver and eventually liver cancer. Standard treatment with interferon and ribavirin only cures about 45% of all patients. But thanks to two new medications, up to 70% of people with hepatitis C may be be cured. More than 40 medications are in development.
