Filter by:The purpose of this study is to determine the most effective way to give patients information regarding hepatitis C virus infection. The investigators plan to compare the information retained by some patients who are given a brochure alone versus patients who watch an interactive video about hepatitis C.
This is a one-time cross-sectional survey study of approximately 200 self-identified black or African-American patients who have had chronic hepatitis C viral infection (HCV) that will evaluate patients' willingness to participate (WTP) in health/medical research related to HCV and attitudinal factors that might be associated with WTP, such as benefits and barriers to research participation, mistrust of physicians/researchers, health literacy, and knowledge of health/research studies.
This is a preliminary trial of a Hepatitis B vaccine (Heplisav-B) in medically immunosuppressed patients. The purpose of this study is to test the ability of Heplisav-B to produce high levels of antibody that neutralize the virus and prevent hepatitis B from coming back. Another important purpose is to test the safety of this vaccine in patients taking immune suppressive medicines.
The objective of this study is to assess the effectiveness of the glecaprevir/pibrentasvir (GLE/PIB) regimen in adolescent participants aged 12 to <18 years of age with chronic hepatitis C (CHC) in clinical practice in the Russian Federation. The study also plans to assess effectiveness of GLE/PIB in subpopulations of interest like co-infected hepatitis C virus (HCV)/human immunodeficiency virus (HIV) adolescents, in various HCV genotype/subgenotype, cirrhotic and non-cirrhotic participants, treatment-experienced (prior treatment with pegylated interferon (pegIFN) or IFN, and/or Ribavirin (RBV) and/or sofosbuvir [PRS]) and treatment-naïve, adolescents who use drugs (PWUD) and non-drug users.
This trial is an experimental, randomized, double blind, prospective intervention study Approximately 100 subjects will be enrolled in this trial, divided into 2 arms, as follow: For adult (18-40 years old)
This is a randomized, double-blind, placebo-controlled trial to assess the efficacy and safety of metformin as add-on to entecavir therapy in patients with chronic hepatitis B.
Background: The global response to the HCV infection epidemic has been transformed by the availability of low-cost curative short course direct acting antiviral (DAA) therapy. Egypt has one of the highest burdens of HCV infection worldwide, and a large treatment programme, but reaching rural communities represents a major challenge. We report the feasibility and effectiveness of a comprehensive community-based HCV prevention, testing and treatment model in 73 villages across Egypt, with the goal to eliminate infection from all adult villagers. Methods: An HCV "educate, test and treat" programme was implemented in 73 villages across 7 governorates in Egypt between 06/2015 and 06/2018. The programme model comprised community mobilization facilitated by a network of village promoters to support the education, test and treat campaign as well as fund raising in the local community; a comprehensive testing, linkage to care and treatment of all eligible villagers aged 12 to 80 years using HCV antibody and HBsAg rapid diagnostic tests (RDTs), HCV RNA confirmation of positive cases, staging of liver disease using transient elastography (FibroScan), treatment with 12 or 24 weeks of a direct acting antiviral (DAA) regimen according to national standard of HCV care, and an assessment of cure at 12 weeks after completion of treatment (SVR12); and an education campaign to raise awareness and disseminate messages about safer practices to reduce transmission through public events, promotional materials and house-to-house visits. Key outcomes assessed in each village were: uptake of serological HCV and HBV testing, linkage to assessment and HCV viral load confirmation, uptake of treatment, and SVR12.
Hepatitis B virus (HBV) infection is a worldwide health problem. It has been proved that the persistence of HBV is associated with the failure to stimulate an efficient HBV-specific immune response. T101, the Chinese counterpart of TG1050, is a replication-defective adenovirus serotype 5 (Ad5) expressing multiple HBV-specific antigens (core, polymerase and envelope) and is used as therapeutic vaccine for chronic hepatitis B patients. The application of T101 aims at inducing a broad HBV-specific cellular immune response and ultimately eliminating HBV infection.
The first purpose of this study is to test the body's protective reaction (making antibodies) to a licensed hepatitis B vaccine (Recombivax-HB) after it is injected either in the arm fat or muscle. Hepatitis B virus is an important cause of liver disease in humans. More than 21% of healthy adults over age 60 years demonstrate evidence of previous Hepatitis B infection using a common blood test. The second purpose of this study is to learn more information about other reasons (such as body fat content, gene types, etc.), why older people respond less well than younger people to vaccines. The Investigators will also learn more about the ability of certain white blood cells, called T cells, to respond to protein signals in the blood. T cells do not seem to respond as well to these protein signals as individuals age. The Investigators will compare results to a younger group of volunteers who have also been vaccinated with hepatitis B vaccine.
The purpose of this study is to evaluate the efficacy of 48-week study intervention with JNJ-73763989+JNJ-56136379+nucleos(t)ide analog (NA) regimen compared to NA alone assessed by HBsAg levels. This study is part of HepB Wings Platform Trial (PLATFORMPAHPB2001).
