Predicting sustained virological responses in chronic hepatitis C patients treated with peginterferon alfa-2a (40 KD)/ribavirin.
Daclatasvir plus sofosbuvir, with or without ribavirin, achieved high sustained virological response rates in patients with HCV infection and advanced liver disease in a real-world cohort.
The IFN- receptors are single-membrane spanning proteins and responsible for signal transduction by increasing binding of ligands.7 Many researchers assessed the amount of IFN receptors' expression and their significant role in response to IFN treatment and patients with sustained virological response (SVR) were found to have significantly higher expression levels of IFNAR-1 a nd IFN AR-2 compared to non-sustained responders.8

found that the rate of sustained virological response was 72% after the treatment of pegylated interferon plus ribavirin and that sustained virological response was significantly associated with a decrease in the liver fibrosis index and an increase in the albumin levels and platelet counts.
In HCV-infected patients, the achievement of sustained virological response (SVR) after treatment reduces the risk of progression to clinical decompensation or development of hepatocellular carcinoma in cirrhotic patients and can even result in histological improvement in those with less advanced fibrosis.
