Hepatitis C genotype 3 isn't a death sentence
By onewhoknows7
We begin with a family who struggle to access HCV therapy. A video with only one picture and a bit of text for us to read, for me - a powerful video. A story that almost anyone who has treated HCV can relate to; falling through the cracks, not receiving quality care, insurance companies deciding when or if to treat patients, is this your story too? In many ways this video hits home for me also, if not for HCV Advocate, I most certainty would have never treated successfully in 1999.
An estimated 130-150 million people worldwide are living with chronic HCV infection, within the six major HCV genotypes, genotype 3 represents 22-30% of all infection, 10% in the United States.
Research has shown people infected with genotype 3 have significantly increased rates of steatosis (fatty liver), fibrosis, and hepatocellular carcinoma (liver cancer), thus making this genotype both difficult and urgent to treat. Here is a quick review of key HCV genotype 3 research articles, with an update from the HCV Guidance .

April 21, 2017 - AbbVie combination cures 97% of genotype 3 hepatitis C
AbbVie's pangenotypic direct-acting antiviral combination of two drugs cured 95% of people with early-stage genotype 3 hepatitis C virus (HCV), the hardest genotype to treat, according to results of the ENDURANCE-3 trial presented at the International Liver Congress in Amsterdam on Friday. The AbbVie second-generation direct-acting antiviral combination consists of a protease inhibitor and an NS5A inhibitor. Glecaprevir is an HCV NS3/4A protease inhibitor active against all genotypes of hepatitis C. Pibrentasvir is an NS5A inhibitor also active against all genotypes of hepatitis C.

Glecaprevir/pibrentasvir is effective for people with HIV/HCV co-infection

Published: 26 July 2017
AbbVie's new pangenotypic regimen combining glecaprevir and pibrentasvir cured almost all HIV-positive people with hepatitis C co-infection in the EXPEDITION-2 study, according to a presentation on Monday at the 9th International AIDS Society Conference on HIV Science (IAS 2017) in Paris.
Karine Lacombe of Saint-Antoine Hospital in Paris presented findings from AbbVie's phase 3 EXPEDITION-2 trial, which evaluated an 8-week regimen of glecaprevir/pibrentasvir for people with both HIV and hepatitis C.
Glecaprevir is an HCV NS3/4A protease inhibitor and pibrentasvir is an NS5A inhibitor. Both are pangenotypic, or active against all HCV genotypes. The two drugs have been co-formulated in a once-daily combination pill, to be marketed under the brand name Maviret.
Studies presented at this year's International Liver Congress showed that glecaprevir/pibrentasvir cured 99% of people with hepatitis C with multiple HCV genotypes, as well as 95% of people with hard-to-treat genotype 3.

The relationship between hepatitis C infection and hepatic steatosis.
Lawrence Serfaty
Key Points
Out of excessive alcohol consumption, steatosis should be classified into 2 types according to hepatitis C virus (HCV) genotypes: metabolic steatosis, which is associated with features of metabolic syndrome and insulin resistance in patients infected with nongenotype 3, and viral steatosis, which is correlated with viral load and hyperlipemia in patients infected with genotype 3.
HCV interacts with host lipid metabolism by several mechanisms, such as promotion of lipogenesis, reduction of fatty acid oxidation, and decreases of lipids export, leading to hepatic steatosis and hypolipidemia.
A strong link between HCV infection and diabetes mellitus has been found in subject based studies and, to a lesser degree, in population-based studies.
