Filter by: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.
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.
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.
Severity of alcoholic hepatitis is defined by Maddrey's discriminant function, value of 32 or higher indicates severe alcoholic hepatitis that carries an adverse prognosis with one month mortality of 30%-50%. Prednisolone (40 mg/day) given orally should be considered to improve 28-day mortality in patients with severe AH. Abstinence is key to long-term survival. According to current protocol, we discontinue the treatment after 28 days but only 15 % patient is achieving the DF < 32 after 28 days of treatment. The aim of this study is to evaluate the role of extended low dose prednisolone (10mg) in achieving remission by day-90 in steroid responsive severe alcoholic hepatitis.
The goal of this clinical trial is to learn about the action of Imdusiran (AB-729) in the liver of people with chronic hepatitis B. The main questions it aims to answer are: - how well is it working in the liver - how does Imdusiran affect the hepatitis B virus Participants will receive injections of Imdusiran, one injection every 8 weeks, for a total of 4 doses. They will also undergo 2 liver biopsies: one with the first dose of Imdusiran, and the second 8 weeks after the last dose of Imdusiran.
Alcohol-associated hepatitis (AH) is a life-threatening condition with high 90-days mortality (up to 40%) and limited treatment options. Previous studies have shown that decreased nutritional intake (less than 21 kcal/kg/day) is associated to a higher mortality compared to patients with a higher caloric intake. Additionally, it has been suggested that subjects with severe AH, should receive a high-protein diet, however, no specific trials have been carried out to address these questions. Thus, the investigators aim to compare nutritional interventions through a randomized controlled trial to assess if a strategy of peripheral parental nutrition (PPN) plus oral nutritional supplementation (ONS) improves outcomes in patients with severe AH. The investigators will compare standard oral intake, enhanced oral intake with IV fluid supplementation, and PPN plus ONS in patients admitted to hospital with severe AH. These results potentially will help guide practitioners on caloric benchmarks targets for patients with severe AH. This study will also assess specific risks and benefits of different nutritional interventions.
