Filter by:Liver stiffness is a marker for scarring of the liver, which occurs after damage from various liver conditions. Scarring prevents normal liver function and can lead to liver failure. Fatty liver is a common cause of liver damage and can contribute to scarring. Currently, liver biopsy serves as the 'gold standard' for assessing the degree of liver scarring and fatty infiltration, guiding treatment decisions. However, liver biopsy poses a significant risk of death and unpleasant side effects, including internal bleeding and pain. Moreover, due to the small sample of liver tissue obtained during the biopsy, the results can be misleading and may not provide an accurate overview of the liver's health. Therefore, there is an unmet need for a non-invasive method of measuring liver stiffness and fat content. Ultrasound-based methods utilize various properties of ultrasound waves to assess liver stiffness and fat levels. This study aims to recruit 100-120 patients with chronic liver disease. The investigators will assess liver stiffness and fat levels during patients' hospital visits for routine scans, biopsies, or clinic appointments. The resulting measurements of liver stiffness and fat obtained through ultrasound-based methods will be compared to patients' routine liver biopsies, routine FibroScan results (another non-invasive method routinely used in clinical care to assess patients' liver stiffness), and other non-invasive severity scores (calculated from results obtained from patients' routine blood tests, providing an overview of the extent of liver damage).
Prospective, cross-sectional, adaptative study to evaluate the clinical performance of the In-Vitro Diagnostics Medical Device MagIA IBC (a Multiplex Point-of-Care Test for the detection of HIV, HBV and HCV) in detecting anti-HIV antibodies (HIV-Ab), anti-HCV antibodies (HCV-Ab), and HBs antigens (HBs-Ag) in serum, plasma, venous blood and capillary blood. If not prescribed for the patient care, blood drawings, and finger pricks will be performed on the patient for the purpose of the clinical study. The Study includes a Technical Adjustment Phase (to identify optimized acquisition parameters and to define the decision threshold for the diagnostic) followed by a Validation Phase (to validate the concordance between the matrices and to evaluate the Specificity and the Sensibility of the diagnostics)
Autoimmune Hepatitis (AIH) is chronic fibroinflammatory disease of the liver characterized by chronic, relapsing liver inflammation, and a risk for progression to liver failure and need for liver transplantation. No AIH-specific registry does exist in Italy, so that the actual epidemiology of the disease in the country is unknown. This is an observational, retrospective and prospective, multicenter study evaluating incidence, prevalence and disease course of AIH in subjects > 1 years old in Italy.
Psychological distress (anxiety and depression) is common in and experienced differently by people living with long-term health conditions (LTCs). Being able to measure whether psychological distress is related to living with a LTC would allow researchers and clinicians to provide interventions specifically tailored to the challenges of living with a LTC and therefore provide the most appropriate support for these patients. Such a measure would also be useful in research to identify the presence of illness-related distress in different patient groups. This project will therefore create a new measure of illness-related distress that has applications for both research and clinical practice. This will involve the psychometric validation of the new illness-related distress measure to test how valid and reliable the measure is. The aim of the project is to provide initial validation of the Illness Related Distress Scale in a community sample, recruited through online platforms. The objective of the study is to gather initial validity and reliability data for the scale.
This Phase 1b clinical study is a multi-center, open-label, dose escalation, prime only, and prime plus boost therapeutic vaccination study of 2 distinct chimpanzee adenoviral vectors (AdC6 and AdC7), containing parts of hepatitis B virus (HBV) core and polymerase antigens fused within glycoprotein D in a cohort of chronic hepatitis B (CHB)-infected adult participants who are currently receiving entecavir, tenofovir (tenofovir alafenamide fumarate or tenofovir disoproxil fumarate), or lamivudine, with documented HBV viral load suppression for at least 12 months. Approximately 24 participants will be enrolled in Group 1 and randomized to Cohort 1a or Cohort 1b. Those assigned to Cohort 1a will receive a low dose prime therapeutic vaccination of vector AdC7 on Day 1, followed by a booster vaccination on Day 91 using vector AdC6. Those assigned to Cohort 1b will receive a low dose prime therapeutic vaccination of vector AdC6 on Day 1, and will not receive a booster vaccination. Group 2 will then enroll approximately 24 participants randomized to Cohort 2a or Cohort 2b. Those assigned to Cohort 2a will receive a high dose prime therapeutic vaccination of vector AdC7 on Day 1, followed by a booster vaccination on Day 91 using vector AdC6. Those assigned to Cohort 2b will receive a high dose prime therapeutic vaccination of vector AdC6 on Day 1, and will not receive a booster vaccination. All vaccine doses will be administered by intramuscular (IM) injection. All study participants will be followed for a total of 1 year post-prime vaccination.
This is an open-label, randomized study to investigate subcutaneous (SC) bepirovirsen when delivered via SC injection from vial or Prefilled syringe fitted with a Safety syringe device (PFS SSD) in healthy adult participants. The aim of this study is to provide relative bioavailability data to support the transition from the vial presentation of bepirovirsen, to a ready-to-use liquid in a PFS SSD when both are given by a health care professional. The study will also assess self-administration using the PFS SDD, and the safety and tolerability of bepirovirsen.
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.
This is a non-interventional retrospective multi-center study for the patients received Entekavir or TDF for Hepatitis B prophylaxis.
Two hundred and ninety-six million people worldwide are chronically infected with the hepatitis B virus (HBV), with around 750,000 deaths each year linked to the development of cirrhosis or hepatocellular carcinoma. Current treatments based on nucleoside analogues (NA) achieve virological cure in only 5% of cases at 10 years. The virological persistence of HBV is explained by the persistence of cccDNA (covalently-closed circular DNA) in the nucleus of hepatocytes. Complex and poorly understood interactions between immunological and virological responses explain the persistence of ccccDNA. A better understanding of the immunological and virological interactions of the intrahepatic compartment during chronic HBV infection is needed to better understand the mechanisms of viral persistence and for research and development of new drugs to achieve the goal of a functional cure for HBV (defined as the prolonged loss of Hepatitis B surface antigen (HBsAg) after cessation of treatment, associated with a decrease in intrahepatic cccDNA or its transcriptional inactivation). The intra-hepatic compartment can be explored by liver biopsy. A fine needle aspiration (FNA) technique is used to characterize primary hepatic tumors, with fewer complications than liver biopsy. One study has validated its use for immunological exploration of the intra-hepatic compartment. Finally, a recently published study confirms a correlation between FNA and liver biopsy virological markers in patients with chronic HBV infection. However, no combined immuno-virological study has been carried out to explore this intra-hepatic compartment by FNA in patients with chronic HBV infection. The investigators will assess the intrahepatic compartment of patients chronically infected with HBV (+/- hepatitis Delta (HDV)) to understand the mechanisms of viral persistence and characterize host immune responses to HBV. These investigations will make it possible to determine the immuno-virological profiles of patients who would benefit from intensification of antiviral treatment or, potentially, discontinuation of antiviral therapy.
