Description: that may be used in the future to predict the response to Sofosbuvir and this will save a huge cost for Egypt .
Measure: relevance of HC RAVs to the outcomes of therapy with Sofosbuvir in treatment of egyptian patients infected with HCV genotype 4 Time: baselineChronic hepatitis C virus (HCV) infection is a major public health problem with an estimated 180 million people infected worldwide. In the United States an estimated 4.1 million people are infected and HCV is the principal cause of death from liver disease and leading indication for liver transplantation. Within HIV/HCV co-infected patients, liver disease due to Hepatitis C progresses even more rapidly. While combination of ribavirin (RBV) and pegylated interferon (PEG) in combination with boceprevir/telaprevir is the currently recommended therapy for chronic HCV infection and has superior cure rates compared to PEG+RBV alone in HCV monoinfected patients, treatment is still associated with a high incidence of adverse events (AEs), discontinuations and poor cure rates in several populations. Within the HIV/HCV co-infected population treatment for HCV remains complicated given drug interactions between anti-retrovirals and HCV protease inhibitors, in addition to the extensive side-effects due to PEG +RBV alone. Recent studies have demonstrated that the use of a combination of anti-virals which target HCV without interferon (IFN) can cure HCV, without additional toxicities. These novel therapies that do not rely on an IFN backbone may additionally enhance cure rates in HIV/HCV co-infected, a population which has historically been difficult to cure. The findings from this study will aid in the understanding of antiviral and host responses and determinants of response to an IFN free regimen in HIV/HCV co-infected patients.
