Filter by:The fixed-dose combination of sofosbuvir and daclatasvir in a single pill is being used for the treatment of hepatitis C in Iran. In this study the efficacy of this combination is evaluated in 1000 patient with hepatitis C.
Investigators aim to study the effect of direct acting antiviral agents (DAAs) on behavior of hepatocellular carcinoma (HCC) and overall survival in patients with chronic hepatitis C (CHC).
Background and Aims: Arrival of direct-acting antiviral (DAA) agents against hepatitis C virus (HCV) with high-sustained virological response (SVR) rates and very few side effects has drastically changed the management of HCV infection. The impact of DAA exposure on hepatocellular carcinoma (HCC) recurrence after a first remission in patients with advanced fibrosis remains to be clarified. Methods: 68 consecutive HCV patients with a first HCC diagnosis and under remission, subsequently treated or not with a DAA combination, were included. Clinical, biological, and virological data were collected at first HCC diagnosis, at remission and during the surveillance period.
Approximately 3.5 - 5 million Americans are living with hepatitis C virus (HCV) in the United States. HCV significantly impacts rural Pennsylvania. It is estimated that 160,000 adults in Pennsylvania are living with hepatitis C. In 2010, Center for Rural Pennsylvania estimated that 27% of population of PA live in one of Pennsylvania's 48 rural counties. Under this estimate, there are over 43,000 individuals affected with chronic HCV living in rural Pennsylvania. Rural county residents often experience barriers to health care by having fewer primary care providers and limited specialty care physicians available to them to address their healthcare needs. RQ1: Will the community based delivery system for Hepatitis C screenings see an increase in positivity rates? HO1: There is no relationship between the community based delivery system with an increase in the Hepatitis C screening positivity rates. HA1: There is a relationship between the community based delivery system with an increase in the Hepatitis C screening positivity rates.
Hepatitis C virus (HCV) infection is easy to chronic and can progress to cirrhosis and liver cancer. Direct-acting antiviral treatment can significantly improve the prognosis of the disease and the efficacy is seemingly not affected by a variety of viral factors. In addition, direct-acting antiviral agents therapy may affect the transformation of the immune cells and ameliorate the host immune status consequently. This study mainly investigated the relationship between Direct Acting Antiviral Treatment effect and the functional activity of myeloid-derived suppressor cells (MDSCs) and natural killer cells (NK cells) in Chronic Hepatitis C.
Grazoprevir plus elbasvir 12 to 16 weeks is now approved for chronic hepatitis C (CHC) genotype 1, 4, or 6 infection regardless liver disease severity. The current study aims to explore the efficacy and safety of 8-week grazoprevir/elbasvir in HCV-1b patients with mild liver fibrosis
A phase 3 Randomized, Open-Label, Study to Evaluate the Safety and Efficacy of the combined single dose of Dactavira Plus (EPGCG, Sofosbuvir , Daclatasvir & Ribavirin) versus Sofosbuvir + Daclatasvir + Ribavirin (Part A) and a single dose of Dactavira (EPGCG, Sofosbuvir & Daclatasvir) versus Sofosbuvir + Daclatasvir (Part B) in Egyptian Adults with Chronic Genotype 4 HCV Infection.
Chronic hepatitis C infection is a global worldwide health problem with an increasing burden year-by-year, particularly in areas with a high endemicity like Egypt . The World Health Organization estimates that approximately 200 million people worldwide are infected with hepatitis c virus. In Egypt, it was estimated that 15 % of Egyptians have serologic evidence of hepatitis C viral infection .
This early post-marketing study is an observational, prospective and descriptive study of patients receiving daclatasvir for the treatment of Chronic Hepatitis C at participating sentinel sites for the CNFV in Mexico.
Anti-viral, hepatitis C virus (HCV)-specific immune T cell responses are functionally defective in patients with chronic hepatitis C and this functional impairment is believed to contribute to virus persistence. Persistent exposure to high virus loads is likely involved in the pathogenesis of T cell dysfunction. The underlying hypothesis of the project is that the level of anti-viral immune dysfunction in chronic HCV infection is a causal factor which can influence non-response to therapy. Although the rate of response to direct anti-viral agent (DAA) therapy, in untreated, non-cirrhotic, patients is between 95% and 100%, however, the response rate is lower in specific subgroups of patients, including genotype 3 cirrhotics and patients with decompensated cirrhosis, irrespective of the infecting genotype. Aim of the present study will be thus to understand whether non-response to therapy is associated with a wider and deeper anti-viral immune dysfunction, by comparing individual HCV-specific T cell responses in two groups of responder and non-responder patients. Characterization of protective immunity in non-responder patients could allow to identify baseline predictors of non-response to therapy to be used in the daily clinical practice. Objective of the study will be to compare the features (intensity and quality) of the overall HCV-specific immune T cell response in patients non-responder and responder to DAA therapy. To achieve this goal, T lymphocytes (either CD4 or CD8) isolated from the peripheral blood of the patients, before starting DAA therapy, will be stimulated with HCV proteins to evaluate the capacity of those cells to expand, produce cytokines and express cytotoxic capacity.
