Efficacy and Safety of Bulevirtide (BLV) Therapy in HDV Chronic Hepatitis (CHD) in Italy
Hepatitis DSpontaneous, pharmacological observational, no-profit, retrospective, multi-center. 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 retrospectively/longitudinally. The primary objective of the study is to describe the virological response to BLV in all patients starting BLV therapy, 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. All patients with active HDV chronic hepatopathy (quantifiable HDV-RNA) who initiated treatment with BLV 2 mg/day during the study period at the S.C. Gastroenterology and Hepatology (Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico) and at participating centers, and who met the inclusion criteria and none of the exclusion criteria.

Quantitative Magnetic Resonance Imaging to Aid Clinical Decision Making in Autoimmune Hepatitis....
Autoimmune HepatitisThis will be a prospective, observational, cross-sectional study designed to assess how a quantitative Magnetic Resonance Imaging (MRI) scan will aid in a physicians' clinical decision making process in patients with suspected or confirmed Autoimmune Hepatitis (AIH). Participants will be recruited from the specialist outpatient hepatology clinic at Kings College Hospital NHS (National Health Service) Trust who are either being seen as a new or follow-up patient. Participants will be treated and assessed in line with the normal clinical care pathway. Autoimmune hepatitis is relatively rare, with a prevalence of about 8,000 people in the United Kingdom (UK) diagnosed. It is a non-resolving liver condition that is usually treated with a combination of corticosteroid and immunosuppressant therapy. The current standard for effective management requires close monitoring of disease activity to balance disease control and unwanted side effects of treatment . The recommended management involves monthly blood tests and annual liver biopsies to verify histological remission . However, blood tests lack sensitivity and biopsy is very invasive and samples only a small portion of the liver . Indeed, liver biopsy remains the gold standard for evaluating liver pathology, however it is not appropriate for longitudinal monitoring due to pain, risk and invasiveness. Blood tests can identify when the liver is inflamed, but are insensitive to small changes and are not prognostic. There is a significant unmet need in this patient group relating to both disease monitoring and identifying those needing higher immunosuppression or transplant. Non-invasive, quantitative MRI can characterise liver tissue to aid in the diagnosis of liver disorders. Using quantitative MRI in the management of AIH patients could be an invaluable asset within the standard care pathway to ensure more appropriate and accurate dosing of steroids is used in AIH patients, thus preventing over/under treating.

Providing PrEP, Hepatitis C Treatment, and MOUD Through Telemedicine at Greensboro SSP
Opioid UseOpioid Use Disorder3 moreThe purpose of this study is to provide medication for opioid use disorder (MOUD) with buprenorphine and naloxone, or bup/nx, pre-exposure prophylaxis (PrEP) for HIV prevention, and/or hepatitis C treatment for persons who inject opioids accessing syringe services programs (SSPs), as part of a comprehensive harm reduction program, and assess the acceptability and feasibility of using telemedicine to implement the program. The initial visit will be conducted in person or remotely via telemedicine given COVID-19 protocols at the SSP site in Greensboro, North Carolina (NC); follow-up visits will be conducted via telemedicine.

Tenofovir Alafenamide to Prevent Perinatal Transmission of Hepatitis B
Chronic Hepatitis BMother-to-Child Transmission4 moreTo investigate the safety and efficacy of tenofovir alafenamide (orally 25 mg per day) treated in inactive chronic hepatitis B virus (HBV)-infected pregnant women with high viral load from the late pregnancy until the delivery date or postpartum 1 month.

Transforming the Cascade Of Hepatitis C Care
Hepatitis CChronicSeveral factors are barriers to effective Hepatitis C care: 1) The majority of Hepatitis C Virus (HCV)-positive patients (45-85 percent) are unaware that they are infected; 2) Only a small minority of those in need of treatment receive it; 3) Members of minorities and older patients are even less likely to receive needed care; and 4) Until recently, even those who were treated had a low chance of clearing the virus or achieving cure; 5) It is possible that older attitudes and expectation of futility might continue to persist among patients and provider in primary care settings. Community Health Centers are often the most culturally appropriate and accessible choices, particularly for underserved populations, with the benefit of ongoing trust and relationships with patients. Therefore, these can be ideal places to deliver complex HCV care if they possess the needed expertise. However, most community-based primary care and community health centers lack access to Hepatitis C evaluation and treatment services, leading to a major public health problem. Thus, investigators propose to implement and evaluate a pragmatic trial to implement and evaluate a multi-disciplinary model for HCV treatment at Currently, the treatment initiation rates at each of these sites is estimated as less than 10%. The investigators hypothesize that our project will increase the rate of participation in all the steps of the HCV care cascade and ultimately lead to more than doubled rates of treatment uptake
