MAGIA H3S Point of Care Test Performance for HIV, HBV, HCV, and Syphilis Screening in Pregnant Women in DR Congo

Performance study to evaluate the clinical performance of the In-Vitro Diagnostic Medical Device MagIA H3S (a Multiplex Point-of-Care test for the combined detection of Human Immunodeficiency Virus (HIV), Hepatitis B and C and Syphilis) from pregnant women attending antenatal care (ANC) services in the Democratic Republic of the Congo. This study aligns with the WHO 2022-2030 strategy for the integrated elimination of mother-to-child transmission of HIV, HBV, HCV, and syphilis.

HIV/HBV/HCV Triple Screening in Primary Care

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.

Analysis of Methylomic Features and Prognostic Risk Prediction in Patients With Hepatitis B-related Acute-on-chronic Liver Failure

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.

Hepatitis B and C Within the Chinese Community in Milan

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.

Immune Dynamics in the Natural History of Chronic HBV Infection

The purpose of this observational study is to follow up on chronic HBV-infected patients over a long period of time to understand the changes in the immune status as age increases and the natural history of chronic HBV infection progresses. The main questions it aims to answer are: * Does the natural history of chronic HBV infection progress with changes in HBV-specific immunity? * What is the role of age in the natural history of chronic HBV infection? Patients with chronic HBV infection who are untreated and aged 1-80 years will be followed up every six months. During each follow-up, HBV-related serological and virological indicators will be tested. Peripheral blood samples will also be collected to test HBV-specific immunity and the immune environment.

Zinc Sulphate in Treatment Fibrosis in HBV Patient Receiving Antiviral Therapy

This study aims to investigate the possible safety and efficacy of Zinc sulphate as antifibrotic agent in chronic HBV patient receiving antiviral therapy.

Occult Hepatitis B Virus Infection and HBV Reactivation After Switching to Long Acting Therapy in Patients With HIV-1

The primary objective of the present project will be to investigate the risk of HBV reactivation (from virological reactivation to overt HBV infection) in HIV-1 carriers with occult HBV infection (OBI, is characterized by the absence of surface antigenemia, HBsAg negativity, with the presence of HBV-core antibody, HBcAb) and switching from antiretroviral therapy (ART) including nucleos(t)ides to long-acting formulation.

Study of EPI-003 in Select Nucleos(t)Ide Analogue-Treated, Chronic Hepatitis B Patients

This study is an open-label, 2-Part (Single Ascending Dose \[Part 1\] And Dose Expansion) study that will evaluate the safety of EPI-003 administered to patients with chronic infection with HBV (CHB). EPI-003 is a liver-targeted antiviral therapeutic for intravenous (IV) injection that is capable of precise epigenetic modifications of the HBV genome without causing mutations in the gene sequence itself. This study is designed to determine the safety and pharmacokinetic (PK) and pharmacodynamic (PD) profile of EPI-003 in this patient population.
