The purpose of this observational study is to employ single-cell multi-omics and spatial omics technologies to characterize the spatial and immune structures within the livers of patients with fatty liver, hepatic hemangioma, focal nodular hyperplasia, liver fibrosis, cirrhosis, and HBV infection. The primary questions it aims to address are: Investigate the mechanisms of liver degenerative changes during the processes of liver aging, fatty liver, HBV infection, liver fibrosis, and cirrhosis. Characterize the molecular features and cellular networks at different stages of liver degeneration and identify new targets and mechanisms for the cure of the aforementioned diseases. The study will collect peripheral blood and discarded liver tissue from patients with hepatic hemangioma, fatty liver, HBV infection, liver fibrosis, and cirrhosis who are undergoing hepatectomy or liver biopsy.

HDV is an RNA virus that infects only in the presence of HBV, affecting about 13% of HBsAg carriers. In Italy, prevalence ranges from 3.2% to 9.3%. It increases the risk of cirrhosis, fulminant hepatitis, and HCC, particularly in high-risk groups (HIV, HCV, drug users, dialysis patients). Until 2020, pegIFN was the only therapy; since 2022, bulevirtide (BLV) has been available, blocking viral entry into hepatocytes and reducing HDV RNA and liver stiffness, with efficacy in 45-48% of patients, though the optimal treatment duration remains uncertain. The gut microbiota and bile acids also play a role in fibrosis and cirrhosis progression: dysbiosis, typical in cirrhotic patients, alters bile acid metabolism and increases intrahepatic toxicity.

NCT07317687
West Virginia faces rising rates of HIV, hepatitis, and syphilis, particularly among individuals experiencing homelessness, substance use, and mental health challenges. Traditional blood-draw testing for these infections is often hindered by mistrust, logistical barriers, and delays in results. This study, conducted by the West Virginia University (WVU) Street Medicine program, evaluates a rapid, point-of-care fingerstick test for HIV, Hepatitis C, and syphilis that provides results within 10-20 minutes during mobile clinic visits. Participants may choose rapid testing, traditional blood draw (which also includes Hepatitis B screening), or decline testing. All participants will be invited to complete a brief survey about the experiences with screening methods. The goal is to assess whether rapid testing improves screening uptake, linkage to care, and patient satisfaction, ultimately reducing barriers and disease burden in high-risk populations.
NCT06372990
Prospective, non-pharmacological, single-center, non-profit observational study. The study design allows longitudinal evaluation of the immune response during the natural history of the infection and/or treatment, correlating the data with the outcome of the disease and antiviral therapies, which will be collected as study variables from the source documents. The study population will be patients suffering from chronic HBV infection with or without HBV-HDV co-infection followed at the Division of Gastroenterology and Hepatology of Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico. The present study is part of an international cooperation project between the Division of Gastroenterology and Hepatology, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico (Milan, Italy) and the Duke-NUS Medical School, Singapore, financed by a grant (project MAECI-2023-23683653) and divided into two specific Work Packages: * WP 1 Milan team (WP1.1 - Clinical and virological phenotyping of CHB and CHD patients; WP1.2 - Clinical evaluation of rapid HBV T cell test in CHB and CHD populations) * WP 2 Singapore team (WP2.1 - Applicability of the rapid T cell assay approach; WP 2.2 - Optimization of the rapid T cell assay protocol) The primary objective of the study is to define the prevalence of specific T cell responses in patients with chronic HBV and HBV-HDV infection, through the application of a specific rapid T cell assay.
NCT06671093

NCT07031219
Design: This will be a within-subjects repeated-measures design, testing an electronic medical record pop-up alert linked to order panels for screening blood tests for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). Study participants will be primary care providers. For each participating provider, their encounter will be randomized to either control (no alert; no changes to EMR interface) or an alert with triple-testing order panel intervention arm (alert linked to order panel with screening tests for all three bloodborne viruses (BBVs) selected by default; the alert will be triggered when a provider attempts to order a screening test for at least one BBV). The alert linked to triple testing orders will only be triggered if the provider orders a virus BBV screening test based on their normal practice and standard of care for their patient. Providers will see which orders are selected prior to signing (finalizing) them; therefore, this study will be unblinded. To mitigate the effect of unblinding, randomization will occur at the encounter level which will lead to providers experiencing both the control and intervention conditions randomly throughout the duration of the study. Outcomes/endpoints: The investigators will compare incidences of HIV, HBV, and HCV diagnoses between the two encounter conditions, estimate number of cases missed by not triple-testing, estimate laboratory costs per condition, and measure patient encounters per condition.

This study aims to determine the prevalence of antiviral drug resistance among Egyptian patients with chronic hepatitis B virus (HBV) infection and to identify the associated demographic, clinical, and virological risk factors. Understanding patterns of resistance will help improve treatment selection and optimize long-term management strategies for HBV patients.
NCT07275554
This study aims to investigate the methylomic features of patients with hepatitis B-related acute-on-chronic liver failure and establish and validate a prognostic risk prediction classification model. The findings are of significant importance for guiding clinical practice and improving patient prognosis. Additionally, a methylomics-based classifier model for liver failure will be developed for disease prognosis analysis and clinical assessment, with the potential to enhance the diagnostic efficiency of liver failure.
NCT07241962
The goal of this observational study is to assess the effectiveness of targeted screening for Hepatitis B (HBV) and Hepatitis C (HCV) infections in adults aged 18 to 50 from the Chinese community residing in Milan. The main questions it aims to answer are: * Does community-based, culturally sensitive screening increase the detection of undiagnosed HBV and HCV infections in this high-risk population? * What is the level of adherence, satisfaction and awareness regarding rapid testing methods in this community? Participants will: * Receive pre-test counseling in Italian or Chinese with the help of an interpreter * Complete a brief, anonymous questionnaire on demographics, risk factors and awareness of HBV/HCV * Undergo capillary rapid testing for HBV and/or HCV * Receive test results during the same visit * Complete a short post-test satisfaction questionnaire The study will be conducted in public spaces within Milan's Chinatown, during monthly sessions, until 1,000 participants are enrolled. Each session will last approximately 30-60 minutes per participant.
NCT07231276
In this study, comparisons will be made between the treatment group (which will receive pegylated interferon alfa-2b treatment) and the observation group (which will receive no drug treatment or be treated with nucleos(t)ide analogs). The primary objectives are to address the following questions: compare the efficacy evaluation indicators (with clinical cure rate as the primary one) between the pegylated interferon alfa-2b treatment group and the observation group; assess whether pegylated interferon alfa-2b treatment improves the clinical cure rate in patients with chronic hepatitis B virus (HBV) infection aged 3 years and above but under 18 years (adolescents and children); and explore optimized antiviral treatment regimens for adolescents and children with chronic HBV infection. The secondary objectives are to address the following questions: compare the immune response characteristics between adolescents and children with chronic HBV infection who achieved functional cure after pegylated interferon alfa-2b treatment and those who did not; investigate the immune mechanism underlying the achievement of functional cure in adolescents and children with chronic HBV infection treated with pegylated interferon alfa-2b; and identify plasma markers associated with treatment efficacy for predicting therapeutic outcomes.
NCT07183293
This study is a multicenter, randomized, prospective trial designed to evaluate the efficacy and safety of pegylated interferon α-2b (Peg-IFN-α2b) combined with nucleos(t)ide analogues (NAs) versus NAs monotherapy in patients with compensated hepatitis B cirrhosis. A total of 30 patients with compensated HBV-related cirrhosis will be enrolled and randomized in a 2:1 ratio to either Experimental Group 1 (n=20) or Experimental Group 2 (n=10). The treatment regimens consist of Peg-IFN-α2b combined with NAs (ETV/TAF/TMF/TDF) or NAs (ETV/TAF/TMF/TDF) monotherapy.
NCT07053449
The goal of this qualitative study is to explore the impact of antiviral treatment, or none, for chronic hepatitis B virus on the non-clinical (social) harms experienced by migrant populations living in the UK. Two groups of participants living with hepatitis B virus will be interviewed, those taking the daily treatment, and those not prescribed any treatment.
NCT02344680
A cohort of adults with HIV-HBV co-infection will be created in Lusaka, Zambia, to describe the short and long-term (up to 10 years of follow-up) HBV and liver outcomes, including the effectiveness of current therapies, and to identify the risk factors for major endpoints of interest, including HCC and HBV functional cure. This cohort will also create a pool of potential participants for in-depth mechanistic studies and clinical trials of novel HBV cure drugs.
NCT07007286
This study is a prospective, multicenter, real-world cohort study designed to compare the long-term outcomes of chronic hepatitis B patients with a family history of HBV-related hepatocellular carcinoma (HCC) who receive PEG IFNα-2b combined with nucleos(t)ide analogues or nucleos(t)ide monotherapy. The primary endpoint is the incidence rate of HCC, and secondary endpoints include the rate of HBsAg seroclearance, changes in liver fibrosis, and survival rates. The study will last for 5 years and enroll approximately 15,000 patients, aiming to provide evidence-based optimization for CHB treatment regimens.
NCT06990438
This study aims to evaluate the effect of long-term use of Tenofovir Disoproxil Fumarate (TDF) on bone density in patients with chronic hepatitis B virus (HBV) infection. Tenofovir is a widely used antiviral medication for the treatment of HBV. While it is generally well tolerated, some studies have reported potential adverse effects on bone mineral density, particularly with long-term use. The objective of this research is to assess whether extended TDF therapy is associated with reduced bone density or increased risk of osteopenia or osteoporosis in adult patients with chronic HBV infection. The study will involve clinical evaluation and radiological assessment of bone health using dual-energy X-ray absorptiometry (DEXA) scans, as well as relevant biochemical markers. This investigation will provide important data on the long-term safety profile of Tenofovir in relation to bone health and help guide future clinical decisions for the management of chronic hepatitis B.
NCT06906016
Chronic Hepatitis B Virus (HBV) infection affects nearly 300 million people worldwide and is a leading cause of liver fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). In France, it affects around 0.3% of the population. Current clinical practice relies on traditional biomarkers, such as HBV DNA and HBsAg, to monitor viral replication and disease progression. However, these biomarkers do not fully capture the viral activity or predict clinical outcomes. Recently, new biomarkers like HBcrAg and HBV RNA have emerged, showing promise for better understanding the natural history of the infection and guiding treatment decisions. The main objective of this research is to evaluate the predictive role of these biomarkers (HBcrAg, HBV RNA) in HBV-infected patients, focusing on their association with HBsAg seroconversion and their ability to predict clinical events like cirrhosis and HCC. Secondary objectives include describing the clinicobiological characteristics of patients, determining HBV genotypes, characterizing the impact of HBV on the host's transcriptome, and studying the biomarkers' role in different phases of the infection and treatment. The ultimate goal is to identify more accurate biomarkers to guide antiviral treatment, predict disease progression, and potentially determine when treatment can be safely discontinued.
