Hepatitis C affects approximately 180 million people worldwide, with 3-4 million newly infected each year. Hepatitis C virus (HCV) has been classified into seven different genotype categories, wherein HCV genotype 1 (HCV-1) is the most prevalent. To date, there is still no vaccine available against HCV infection. Until recently, combination therapy of pegylated interferon-a (PegIFN) and ribavirin (RBV) has been the standard of care. Nevertheless, for many patients, particularly those infected with HCV genotype 1 (HCV-1), this treatment has resulted with unsatisfactory treatment response rates and high adverse drug reaction (ADR) rates. Many clinical factors, including pharmacogenetics, influence the treatment response rate. This review focuses on the association between pharmacogenetics and HCV antiviral therapy in patients infected with HCV genotype 1 and other genotypes (GT); patients reinfected with HCV after liver transplantation; and patients coinfected with HCV and human immunodeficiency virus. Data considering triple therapy in HCV-infected patients are also reviewed. Additionally, various genetic polymorphisms, with an emphasis to IL-28B, and their association with pharmacogenetic testing in HCV are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
