Filter by:Retrospective and prospective, pharmacological, multicentre, non-profit observational study. Consecutive patients with HDV-related compensated cirrhosis starting Bulevirtide 2 mg/day from September 2019 to December 2025 will be enrolled in the study. Aim of this study is to investigate virological and clinical effectiveness of Bulevirtide 2 mg/day in patients with HDV-related compensated cirrhosis in the real-life setting. Primary endpoint of the study is the rate of virological response, defined as at least 2 Log decline or undetectable HDV RNA compared to baseline, at week 96 of treatment.
The aim of this project is to set up a cross-sectional cohort study (France, Germany, The Netherlands, Poland, Spain, Switzerland, Italy, United Kingdom and Portugal) to assess the implementation of EACS guidelines for HDV-testing among PLWH with positive HbsAg and thereby evaluate the prevalence of HDV infection among HIV/HBV-coinfected in 2023, as well as corresponding risk factors. In addition to the testing itself, this study will also set up a cohort and databasee for future HDV studies among PLWH, including clinical, virological und laboratory parameters. 1. Analyze the rate of HDV-testing and evaluate the prevalence of HDV-infection by testing. 1. Evaluation of former screening of HDV by assessing existing data at study sites. 2. Determination of the HDV prevalence in European PLWH and HBV coinfection. 2. Setting up a database of all PLWH with HBV/HDV coinfection 1. Analysis of transmission risk factors for HDV coinfection 2. Asses the rate of HDV positive patients with ongoing HDV replication. 3. Define the liver disease state by APRI score, fibroscan, ultrasound and routine laboratory test results.
The aim of these study to determine the prevalence of hepatitis Delta virus (HDV) infections and the prognosis of HDV patients in Turkey's southeast. The investigators intend to arrange training sessions for 250 family physicians in Diyarbakir, Batman, Mardin, and Sanliurfa in order to determine those goals. The investigators will talk about diagnosing hepatitis B virus (HBV), HDV, hepatitis C virus (HCV), and Human Immunodeficiency virus (HIV) infections during these events. To ensure that patients with simultaneous HDV infection are evaluated for HIV/HCV and to detect liver fibrosis with a non-invasive method.
Multicenter pharmacological observational prospective, no-profit, study. This study was designed to get a "real-life" snapshot across several Italian Hepatology centers. All HDV patients are followed up according to EASL 2017 guidelines. This allows uniformity on the indication for antiviral treatment and management of that antiviral therapy. No off-label medications are used. All data are retrievable from the patient's medical record. In addition, clinical and biochemical data from patients at month 0, 1, 2, 4, 6 and 12 of treatment, and otherwise within the study period, will be collected longitudinally. The primary objective of the study is to describe the virological response to BLV in all patients starting BLV therapy for CHD, defined as a >2 Log decline in HDV-RNA or undetectable HDV-RNA (using the Robogene 2.0 quantitative kit, LLQ <6 IU/ml) at month 12 of therapy. HDV patients who will start therapy with BLV 2 mg/day from May 2023, according to AIFA guidelines, will be consecutively enrolled.
This observational study will be conducted in patients with chronic co-infection with hepatitis B and D viruses, with negative PCR for HDV RNA in peripheral blood and no signs of active liver inflammation according to blood chemistry parameters, receiving background therapy with bulevirtide for more than 48 weeks and liver biopsy performed or prescribed to be performed as part of routine practice. After the patient has signed the Informed Consent, a portion of the liver biopsy collected as part of routine practice will be sent to the laboratory for PCR testing for HDV RNA, background therapy with bulevirtide will be interrupted, and the patient will be observed in the clinic in accordance with routine medical practice, but at least once times every 4 weeks, for timely detection of relapse of the hepatitis D and initiation of antiviral therapy. Once a relapse of viral hepatitis D is determined via the PCR HDV RNA, the patient's participation in the study will be terminated. The collected data will be analyzed to assess the probability of relapse-free over time. Separate tests will also be conducted for subgroups of patients based on covariates such as duration of previous background therapy with bulevirtide, duration of HDV suppression, use of any other concomitant antiviral therapy during bulevirtide treatment.
The aim is to assess the efficacy and specific safety in an observational study of patients with Chronic hepatitis D (CHD) with prospective follow-up, with antiviral treatment of 2 mg Bulevirtide (BLV) +/- PEG-IFNα-2a and +/- NA given as part of the patient's routine medical care. Also, explorative endpoints of biomarkers in peripheral blood, saliva, fecal sample and/or intrahepatic markers/signatures, and quality of life outcomes will be assessed.
Our global objective is to draw up a photograph of HDV patients over one year in metropolitan France and identify the barriers of screening and care. The investigator suspects a mismatch between HBV and HDV screening, the first step for specialized care pathway in metropolitan France.
This study aims to assess the efficacy and safety of bulevirtide (BLV) in chronic hepatitis D patients treated in Greek liver centers.
Rationale: Hepatitis delta virus (HDV) is a defective RNA virus that requires presence of hepatitis B virus (HBV) to complete virion assembly and secretion. HBV-HDV coinfection ("hepatitis delta") has been associated with severe liver injury that may result in rapid progression to cirrhosis and hepatic decompensation, as well as a higher risk of liver cancer when compared to patients with HBV mono-infection. Given the low incidence of hepatitis D, experience in caring for individuals with hepatitis delta is limited and management practices vary. Objective: Generate prospective follow-up data to increase our understanding of this rare disease. Study design: Prospective observational cohort study spanning 5 years, during which we will collect standard clinical data as well as blood samples and quality of life questionnaires. Study population: hepatitis delta patients aged ≥18 years Intervention (if applicable): not applicable Main study parameters/endpoints: Incidence of liver related events (liver cancer, (decompensation of) cirrhosis, liver transplantation) during follow-up and changes in markers of viral replication, inflammatory activity and liver stiffness over time. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The risks associated with participation can be considered negligible and the burden can be considered minimal. The only additional action that the participants must perform are the filling out of two annual quality of life questionnaires, which are considered non-invasive, and collection of 10 ml blood during regular blood sample collections
This is a multicenter, randomized, controlled, open-label, Phase IIb study of HH-003 injection, HH-003 injection is a monoclonal antibody targeting Hepatitis B virus. This study aims to assess efficacy and safety in subjects with chronic hepatitis delta virus infection.
