Filter by:The main risk factor for development of hepatocellular carcinoma (HCC) is cirrhosis of any etiology, with an annual incidence risk between 1-6%; currently the leading cause of death in patients with cirrhosis and the 2nd cause of death by cancer worldwide. Chronic hepatitis C (HCV) is the first single cause associated to cirrhosis and HCC in the Western world. With the advent of new direct antiviral agents (DAA) of chronic HCV infection, virological cure generally exceeds 90% of the cases. Previous studies have shown that the incidence of HCC is lower in patients with virologic cure after treatment with pegINF schemes. However, recently published data, open up more controversy regarding the incidence of HCC after virologic cure with DAA. An increasing incidence of HCC after virologic cure in patients treated with DAA has been observed, opening a paradox yet unexplained. This project proposes to answer the following clinical research question: in patients with HCV cirrhosis treated with DAA, is there a change in the incidence of hepatocellular carcinoma? To answer this question a prospective longitudinal cohort study of patients with Child Pugh A-B cirrhosis will be held at 3 years minimum follow-up. A minimum of 210 patients will be included with clinical or histological or non-invasive diagnosis of cirrhosis Child Pugh A or B, with HCV treated with DAA and without hepatocellular carcinoma at the time of enrollment. From this cohort, patients who develop HCC during follow-up will be identified. Routine screening will be done through ultrasound every 6 months in all subjects enrolled and the diagnosis of HCC will be according to recommendations of European and American guidelines.
This is an open, uncontrolled study of twenty-five chronic HCV infected patients carried out at Yassin Abdel Ghaffar Charity Center for Liver Disease and Research. The aim of this study is to investigate the safety & efficacy of combined therapy ledipasvir (LDV) and sofosbuvir (SOF) for treating HCV Genotype 4 in children aged 8 to 18. Due to previous positive results in other clinical studies of this drug it is expected that the drug will have high safety and high efficacy. Safety will be measured by checking for adverse effects, while efficacy will be measured by Real-Time Quantitative Polymerase Chain Reaction (qPCR) detecting viral nucleic acids in blood samples.
This prospective open label study is designed to screen all available Gaucher disease patients [either on enzyme replacement therapy (ERT) or not] for hepatitis C virus (HCV) infection. Furthermore to evaluate the safety and effectiveness of combined Sofosbuvir/Ledipasvir regimen given for 12 weeks in chronically infected patients aged 6-18 years.
The overall goals of the ETHOS II Project are to enhance hepatitis C virus (HCV) care in drug treatment clinics and needle and syringe programs (NSPs) in New South Wales and Australia, and to develop a translational framework for subsequent establishment of HCV screening and treatment programs in drug treatment clinics and NSPs across NSW and nationally.
The purpose of this study is to evaluate the feasibility of implementing a cohort of patients with Hepatitis C in order to generate a larger cohort for future studies
- Unexpected results were published in 2016 showed increased aggressiveness and rates of HCC recurrence after curative treatment of HCC in HCV patients treated by DAAs achieving SVR. On the other hand, the retrospective analysis of ANRS study, did not observe an increased risk of HCC recurrence after DAAs treatment in patients who underwent curative HCC treatment. - Assess the recurrence rate of HCC in HCV infected patients with prior history of treated HCC who achieved rCR with and without administration of DAAs and assess the effect of its timing.
A retrospective and prospective study among people living with HIV (PLWH) that assesses hepatitis C (HCV) treatment uptake during periods before and after direct acting antivirals (DAA) introduction, and its impact on the HCV epidemic among PLWH.
The study hypothesis is to determine the feasibility of switching HIV-HCV co-infected patients receiving methadone or buprenorphine/naloxone as opioid substitution therapy with suppressed HIV RNA viral load on current antiretroviral therapy to elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF, Genvoya™) followed by 12 weeks of HCV antiviral therapy with sofosbuvir/velpatasvir (SOF/VEL, Epclusa™), followed then by switch to bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF, Biktarvy™) for an additional 48 weeks.
This is an interventional Phase II/III, single center, single arm clinical trial to assess the pharmacokinetics, efficacy, safety and tolerance of daclatasvir plus sofosbuvir in treatment-naïve, non-cirrhotic adolescents with chronic HCV GT-4 infection. A single-arm evaluation of daclatasvir/sofosbuvir will focus on the pharmacokinetics, efficacy and safety All enrolled patients will receive daclatasvir 60 mg orally once daily plus sofosbuvir at a dose of 400 mg orally once daily for 12 weeks.
Hepatitis C infection is a major cause of chronic liver disease and death with approximately 3% of the world's population is infected with hepatitis C virus (HCV). New drug therapies called new direct-acting antivirals (DAAs) have been developed and have proven to be well tolerated with minimal side effects. The current costs of these agents are extremely high, however, they provide an opportunity to cure most patients of HCV if they can access and adhere to treatment. The bigger challenge is to engage and cure underserved groups who are not accessing medical care, or who have other complex problems, including homelessness, incarceration, and substance misuse problems. Strategies to improve HCV case detection and case management have much to learn from other infectious diseases. Tuberculosis (TB) disproportionately affects in large part the same group of individuals and community models of care have been used with great success. Strategies such as active case finding, community based screening and treatment, directly observed therapy (DOT) and peer support have all shown high rates of case detection and treatment completion. These strategies are currently being used by the Find&Treat team, UCLH NHS Trust and this study will ain in evaluating it's effectiveness. Previously used to aid homeless patients engage with treatment services for TB, it is now being used with other disease groups such as HCV. This observational study aims to assess the effectiveness of community based interventions with peer support to improve case detection, carry out pre-treatment assessments and assist underserved populations through HCV treatment by the Find&Treat service.
