Filter by:Hepatitis C virus (HCV) infection remains a significant health problem in our country. The World Health Organization estimated that 71 million people worldwide had chronic HCV infection in 2015. And 399,000 people died from cirrhosis or primary hepatocellular carcinoma caused by HCV infection. In 2006, the positive rate of HCV antibody in the population aged 1-59 was 0.43%. Therefore, it was estimated that there were about 5.6 million HCV infected people in the general population, and about 10 million cases of HCV infected people in high-risk groups and high incidence areas. Universal genotype direct antiviral agent (DAA) is the preferred antiviral therapy for hepatitis C. Sofosbuvir/velpatasvir are direct antiviral agents for hepatitis C. The results of Asian clinical trials mainly in Chinese population showed that the sustained virologic response (SVR) rates of sofosbuvir/velpatasvir at 12 weeks in genotype 1a, 1b, 2, 3a, 3b and 6 were 100%, 100%, 100%, 95%, 76% and 99%, respectively. Limited data showed that the SVR rate of sofosbuvir/velpatasvir at 12 weeks was 96% in Chinese genotype 3b patients without cirrhosis and 50% in patients with cirrhosis. After standard antiviral therapy for hepatitis C, there are still some patients who cannot obtain SVR, and these patients are defined as DAA-experienced patients. The guidelines recommend that Sofosbuvir/Velpatasvir combined with ribavirin be used as salvage therapy for patients with DAA-experienced failure. Vosevi is a new generation of antiviral therapy for hepatitis C, which contains three components, (Sofosbuvir, Velpatasvir and Voxilaprevir. It was a salvage treatment plan for DAAs-experienced patients which was recommended by the Chinese hepatitis C prevention and treatment guidelines in 2019. However, there are insufficient data on the proportion of SVR acquired in Vosevi treated DAAs-experienced patients in Asian populations and the effectivity of antiviral therapy between Vosevi and Sofosbuvir/Velpatasvir combined with ribavirin. In the present study, the investigators enroll DAAs-experienced hepatitis C patients. The participants are randomly divided into two groups. Then the participants are treated with Vosevi or Sofosbuvir/Velpatasvir combined with ribavirin respectively. All enrolled participants are followed-up for 3 years. Objectives of the present study are as follows: A. To clarify the sustained virologic response rate after Vosevi therapy for DAAs-experienced patients. B. To clarify the safety and efficacy between the Vosevi therapy and the Sofosbuvir/Velpatasvir combined with ribavirin therapy. C. To clarify the changes of biochemistry indexes in DAAs-experienced patients after Vosevi therapy. D. To clarify the virological relapse rate at 12 weeks after Vosevi therapy. E. To clarify the rate of cirrhosis and liver cancer during the follow-up.
Follow up of Chronic hepatitis C Patients with moderate to severe fibrosis and cirrhosis treated with Direct Acting Antivirals after Sustained Virological Response for 4-5 years to detect changes in hepatic fibrosis and liver functions.
Subjects can be classified into two groups, Group 1 include non-cirrhotic patients, Group 2 include cirrhotic patients. All the patients will be received prophylactically TAF for 4 weeks before using SOF/VEL once daily for 12 weeks. In total, Group 1 patients will be discontinued TAF once daily therapy at the end of week 28 if no HBV reactivation occurs during treatment , Group 2 patients will be received TAF once daily for 64 weeks. In this study, after week 64, Group 2 patients will continue NUC treatment but pay by themselves. For those who is GT3 cirrhosis patients, RBV added simultaneously with SOF/VEL for 12 weeks. For patients weighing < 75 kg, the dose is 500 mg twice; for patients weighing ≥ 75 kg, the dose is 600 mg twice.
This study is a two-way, non-interventional long-term dynamic follow-up clinical observational cohort study. In the Second Division of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, chronic hepatitis C patients who were treated with interferon combined with ribavirin (PR) antiviral therapy (PR treatment for 6 months or more) and / or direct acting antivirals (DAAs ), and the baseline, antiviral treatment and discontinuation follow-up data of patients before antiviral treatment were collected, and follow-up observations of patients were carried out for every 3-6 months. The clinical data such as clinical biochemistry, HCV RNA and serological indicators (anti-HCV), AFP, and liver imaging (liver ultrasound) were collected during the study period. The virological response and clinical outcomes of chronic hepatitis C antiviral therapy were observed for at least 144 weeks. The incidence of liver cancer and decompensated liver cirrhosis after discontinuation of the drug was the main evaluation index. The aim is to explore long-term virological response and clinical outcomes, and elucidate its influencing factors.
Observational Study to check metabolic changes between two different hepatitis C antiviral medication groups. This study will evaluate the impact of different treatments on Serum lipid changes, fasting blood glucose and glycated hemoglobin . It will determine if changes are due to different Antiviral regimens or due to different Sustained virological response rates.
The aim of CELINE is to retrieve and re-evaluate lost to follow-up chronic hepatitis C patients in the Netherlands.
This study was a clinical observational cohort study of two-way, non-intervention long-term dynamic follow-up. Enrolled in the Department of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, with interferon combined with ribavirin (PR) antiviral therapy (PR treatment greater than or equal to 6 months) and/or direct acting antivirals (DAAs) In patients with chronic hepatitis C, the baseline, antiviral treatment and withdrawal follow-up data before the antiviral treatment were collected, and the patients were followed up for 3-6 months. Clinical data such as clinical biochemistry, HCV RNA and serological markers (anti-HCV), AFP and liver imaging (liver ultrasound) were collected during the study period. At least 144 weeks of observation on the virological response and clinical outcome of anti-viral treatment of chronic hepatitis C, the main evaluation index of liver cancer and decompensated liver cirrhosis after stopping the drug, and exploring the antiviral treatment of patients Long-term virological response and clinical outcomes, clarifying their influencing factors.
The Eliminate Hepatitis C (EC) Partnership project is a multi-site, multi-year project aiming to enhance and extend hepatitis C virus (HCV) care and treatment among people who inject drugs (PWID) through nurse-led models of care in the community and the prison system. The project will implement and evaluate a health service intervention to enhance HCV response by improving health promotion, offering training and education to service providers, streamlining clinical pathways, utilising data systems and surveillance and implementing the results of ongoing research and evaluation. Health services data will be used to assess the impact of the EC nurse-led support, to enhance the clinical pathway and increase HCV testing, linkage to care and treatment uptake in community and prison settings. This will include provider and client interviews and a sentinel surveillance system (ACCESS) that will track and monitor impact indicators including HCV testing, linkage to care and treatment uptake at the service and population level. Overall, evaluation data will be used to monitor the uptake of HCV treatment in PWID, monitor the effectiveness of community- and prison-based treatment program and assess the cost and feasibility of treating >1160 PWID in community-/prison-based program and assess changes in HCV prevalence in Victoria and modelling the impact of treating PWID to inform HCV elimination models in Australia and globally.
The primary purpose of the ANRS 12332 HepNile study cohort is to assess in "Real-Life" condition the efficacy and the safety profile of new Direct Acting Antivirals (DAAs) introduced in the Egyptian National Treatment Programme for the treatment of Chronic Hepatitis C (CHC).
Background and Aims: The prevalence of hepatitis C virus infection (HCV) infection in Punjab, India is 3.29%, with an estimated burden of around 650,000 viremic chronic HCV (CHC) patients. The Mukh Mantri Punjab Hepatitis C Relief Fund (MMPHCRF) was launched in June 2016 to provide free treatment to all CHC aiming to eliminate HCV from Punjab. The study assessed the feasibility of decentralized care and efficacy and safety of 12 or 24 weeks of sofosbuvir (SOF) + ledipasvir (LDV) or SOF + daclatasvir (DCV) ± ribavirin (RBV) in the treatment of CHC patients in a public health care setting.
