A Comparison of different
treatments for HCV
Background
Hepatitis C (HCV) is an inflammatory disease that
affects the liver.
Infection with hepatitis C virus (HCV) is one of the
leading causes of liver failure worldwide, and
resulted in 195 000 deaths in 2010 (Jacobson et
al. 2014).
Background
People at risk are those who:
Unprotected sex with someone who has the
disease
Received an organ transplant from a donor with the
virus
Blood related infection
Background
Approximately 75%–85% of people who become
infected with Hepatitis C virus develop chronic
infection.
Three percent of the world's population is
chronically infected.
Japan has one of the highest rates of hepatitis C
virus (HCV) infection worldwide, with around 2
million people estimated to be infected (Hayashi
et al. 2014).
Sofosbuvir (GS-7977) plus
peginterferon/ribavirin
Patients :
18–65 years old
44 weeks
Sofosbuvir is a pyrimidine nucleotide analog
inhibitor of the hepatitis C virus NS5B polymerase
(Rodríguez et al. 2013).
During day 28 the dosing period, sofosbuvir was
generally safe and well-tolerated (Rodríguez et al.
2013).
Sofosbuvir (GS-7977) plus
peginterferon/ribavirin
(Rodríguez et al. 2013)
Sofosbuvir (GS-7977)
(Liu et al. 2014)
Sofosbuvir (GS-7977)
In conclusion, sofosbuvir-based treatment is
effective and safe in treating chronic HCV
infection, although the SVR*12 of its combination
with RBV, especially in treatment-experienced
patients, requires improvement (Liu et al. 2014).
*SVR= Sustained Virologic Response
IFN-β/RBV and PEG-IFN/RBV
Patients:
65 or older
24–48 weeks
IFN-β/RBV therapy is associated with a lower
incidence of the onset of depression symptoms or
insomnia (Nomura et al. 2014).
The SVR rates of both treatments were similar.
IFN-β/RBV and PEG-IFN/RBV
(Nomura et al. 2014)
Simeprevir plus peginterferon alpha-
2a/ribavirin
Patients:
20–70 years
12 or 36 weeks
Simeprevir plus peginterferon alpha-
2a/ribavirin
(Hayashi et al. 2014)
Simeprevir plus peginterferon alpha-
2a/ribavirin
Patients
18 years and older (HCV genotype 1)
48 weeks
Simeprevir (SVR) plus peginterferonalpha-2a/ribavirin (PegIFNα-2a/RBV)
(Jacobson et al. 2014)
Conclusion
Sofosbuvir with ribavirin and pegylated interferon-
α is the best treatment to battle the Hepatitis C
because is the most efficient, safest and have the
best SVR12 percent. Have a SVR 12 of 89% and
a SVR 24 of 91%.
