his clinical trial was conducted to determine the non-inferiority and safety of prophylactic antiviral treatment of Tenofovir alafenamide (TAF) compared to Tenofovir disoproxil fumarate (TDF) in patients with malignant hematological diseases requiring prophylactic hepatitis B antiviral treatment. Confirm. In the case of TAF, domestic evidence when used as a first-line treatment is insufficient, so in this clinical trial, the virus suppression effect compared to TDF during the first administration of TAF to patients with malignant hematological diseases requiring prophylactic hepatitis B antiviral treatment was investigated. We aim to secure non-inferiority and additionally confirm the safety of TAF's known advantages of reducing renal function damage and protecting bone function.
The goal of this is to verify the clinical efficacy of compound probiotics in reducing HBV infection levels and regulating intestinal flora in patients with chronic hepatitis B. The main question it aims to answer is: • Conventional antiviral therapy combined with a 6-month probiotic intervention was used to evaluate the clinical efficacy of reducing HBV infection levels (HBeAg, HBsAg, and HBV DNA levels) and regulating gut microbiota.
Sexual and gender minorities (SGM), such as gay, bisexual and other men who have sex with men (MSM) and transgender women (TGW), are at high risk of HCV infection. A recently released guideline by the WHO recommended HCVST to scale-up HCV screening. However, data on delivery-services of HCVST kits and uptake of HCV testing using HCVST remain scarce in Latin American countries. Additionally, data on the usability of HCVST in MSM/TGW, especially blood-based tests, still lacking in Brazil. To evaluate the uptake of HCV testing by the strategy of using HCVST ordered by the internet and delivery by the post in key populations (SGM) living in the metropolitan region of Rio de Janeiro (Brazil). Additionally, an Ancillary study will assess the usability of different kits of HCVST in MSM/TGW using PrEP. Study Design and Population: This protocol will be composed of two studies that will be conducted in parallel. The primary study will be a cohort study in which SGM ≥ 18 years old living in the metropolitan area of Rio de Janeiro who request HCVST will be included. The Ancillary study will be a cross-sectional study where adult MSM or TGW attending a presential visit for PrEP (initiation or follow-up) at INI/FIOCRUZ will be eligible for this study. The investigators estimate that 3,000 persons will request home-delivery of HCVST (Primary study) and 250 participants will be included in the Ancillary study.Study Design and Population: This protocol will be composed of two studies that will be conducted in parallel.

The investigators estimate that 3,000 persons will request home-delivery of HCVST (Primary study) and 250 participants will be included in the Ancillary study. Methods: For the Primary Study, a web-based platform will be built for this project and an educational campaign will be developed in dating apps to encourage HCV testing. The web platform will contain modules with information on HCV infection and a log-in to request HCV self-tests that can be delivered by the post or collected in the centralized pharmacy for HCV testing. People will be encouraged to report their HCVST results in the online platform. People with positive HCV antibody will be linked-to-care for HCV infection confirmation and treatment initiation. For the Ancillary Study, MSM/TGW attending presential visits for PrEP at INI/FIOCRUZ will be invited to perform HCVST (blood-based and oral fluid tests) under supervision of a trained healthcare worker. Participants will read written instructions and watch a video explaining the procedures step-by-step for HCVST. A second HCV test using the same kit will be performed by the healthcare worker for concordance analysis. People with positive HCV antibodies will be linked to HCV infection confirmation and treatment initiation. Data analysis: Descriptive statistical analysis will be used to evaluate the characteristics of people seeking HCVST, participant's preferences, uptake of HCV testing using self-test kits and internet technologies, as well as acceptability, usability and result interpretation of HCVST in a sub-sample of participants. Ethical considerations: Locally, ethics approval will be obtained from the INI/FIOCRUZ. International ethics clearance will be obtained from the World Health Organization Ethics Review Committee (WHO ERC). All participants will be informed of risks and benefits of the procedures and that their participation is voluntary. All participants will be required to sign the informed consent (an online agreement for Primary Study) as required by Brazilian regulations to participate in research studies. All data collected will respect The Brazilian General Data Protection Law (Law nº 13.709/2018).
This is a single-center retrospective study. The clinical data of patients with Acute-on-chronic Hepatitis B liver failure who were hospitalized in the Department of Hepatology, Qilu Hospital of Shandong University from January 2010 to July 2023 were collected.
Hepatitis B virus (HBV) infection is a major public health problem and chronic HBV infection affects about 296 million people worldwide and is the leading etiology of cirrhosis and hepatocellular carcinoma globally. China takes up a great deal of the responsibility towards the goal of "eliminating viral hepatitis by 2030" released by the World Health Organization (WHO), as China has the world's largest burden of HBV infection. The current diagnostic rate barely reaches 24%, which is significantly short of the target diagnostic rate of 90% proposed by WHO. Progression from chronic hepatitis B (CHB) to hepatic complications-fibrosis, cirrhosis, and HCC-can be prevented significantly by preemptive antiviral therapy. However, the onset of CHB seldom manifests with typical symptoms, and most cases at their first diagnosis have progressed to end-stage liver diseases. Therefore, early detection of CHB and its complications that not only raises public awareness of preventing infection but also brings the patients into the management system is urgent blocking the progression to cirrhosis and HCC. The study is a prospective and observational study involving community-based screening of chronic HBV infection and related liver diseases systematically among the general population of Guangdong Province, China. Individuals in Maoming City, aged 20-70 years, will be enrolled in the screening group for the HBsAg screening using a finger blood test. Positive participants will receive further examinations including laboratory and imaging examinations to discover HBV-related liver diseases. The control group will be enrolled from the general population in two similar cities. By thoroughly investigating the epidemiological landscape and antiviral situation of chronic hepatitis B through population screening, this study intends to furnish the administration with updated epidemiological data. Additionally, the project seeks to establish a CHB screening cohort to enhance early diagnosis and treatment rates for both HBV-related liver diseases. Collectively, the study aspires to improve the overall prognosis for patients with chronic HBV infection, reduce CHB-related mortality, and ultimately put forward valuable healthcare insights and evidence-based medicine (EBM) practices for the effective implementation of CHB screening and management.
The goal of this clinical trial is to evaluate the persistence of Hepatitis A antibody ~32 years post vaccination in healthy adults. The questions this study will answer are: 1) how long antibody persists and 2) The immune response to an additional dose of vaccine among those with no detectable antibody. Participants will be asked to provide a blood specimen. Those with no detectable antibody will be offered an additional dose of vaccine. The kinetics of antibody response in this population will be summarized.
This is the first-in-human Phase I, double-blind, randomized, placebo-controlled, dose escalating study to evaluate the safety, immunogenicity and preliminary efficacy of the YSHBV-002 in the treatment of CHB in adults ≥18 years old. There will be 3 escalating doses of YS-HBV-002 to be administered intramuscularly: 0.5mL, 1.0mL, and 2.0mL.
The goal of this non-randomised, quasi-experimental, prospective comparative trial is to trial simplified care pathways for hepatitis C testing and treatment for people who inject drugs in Armenia, Georgia, and Tanzania. The main questions it aims to answer are: 1. What is the feasibility of implementing a hepatitis C simplified care and same-day treatment care model in community and harm reduction settings in the three study countries? 2. Does a same-day treatment initiation model involving only POC antibody tests (with a shortened read-time) increase hepatitis C treatment uptake and SVR12 outcome (cure) among people who inject drugs compared with a simplified care model involving POC antibody followed by a confirmatory RNA test? 3. What is the comparative cost-effectiveness between a same-day antibody only hepatitis C testing and treatment model and the simplified care model (POC antibody/confirmatory RNA test) model? Participants will: - be enrolled in a new simplified model of care in each country (Arm 1). After the enrolment target is met for Arm 1 (approx. 3-9 months into implementation) new participants will be enrolled into a same-day treatment trial, using presumptive treatment after a reactive POC test result at shortened read-time (5minutes) (Arm 2) - if in Arm 1, participants will commence SOF-VEL DAA treatment after receiving an RNA test to confirm current hepatitis C infection. They will then continue along the treatment pathway, returning for RNA testing 4-16 weeks after SVR12 to determine cure. - if in Arm 2, participants will begin SOF-VEL DAA treatment on the same day as the 5 minute RDT testing. They will then continue along the treatment pathway, returning for RNA testing 4-16 weeks after SVR12 to determine cure. Researchers will compare cure and participant retention rates between the two groups.
The goal of this intervention research is to learn about the safety and tolerability of 162 with a single ascending dose in subjects with chronic hepatitis B virus (HBV) infection.
