Background: Autoimmune hepatitis (AIH) is a rare chronic and lifelong liver disease. Untreated, disease progresses to end-stage cirrhosis and the focus of therapy is with immunosuppression. Current therapies are limited, not targeted, and associated with side effects that patients report reduce quality of life. AIH is believed to arise as a consequence of genetic & environmental risks. Disease is characterised by impaired immunoregulation, that favours a chronic and relapsing hepatitis. As well as recognising an important role for cytotoxic T cells and regulatory T cells, it has become apparent that in AIH, as well as other related autoimmune conditions, that B-cells are important. AIH is characterised by a plasma cell rich interface hepatitis and elevated IgG concentrations. Furthermore B-cell lineages interact with regulatory T-cells. Off-label use of Rituximab, an anti-CD20 agent, has been described for patients with AIH. A number of other ways of effectively targeting B-cells in the treatment of related autoimmune diseases have also been developed, but there have been limited studies in people living with autoimmune hepatitis. Belimumab is a human monoclonal antibody that inhibits B-cell activating factor (BAFF), also known as B-lymphocyte stimulator. It is approved in the Canada to treat systemic lupus erythematosus and lupus nephritis. It has not been studied before in AIH, but off-label reports are published. In an open-label clinical trial of people living with autoimmune hepatitis, the investigator will now formally study the effect of adding Belimumab to existing standard of care, with the goal being to evaluate treatment efficacy, the ability to reduce the burden of existing therapies whilst still controlling AIH disease, and to describe the tolerability & safety of Belimumab in people with AIH. Study Design: Open label, multi-centre, Canadian clinical trial. Patient population: Patients with autoimmune hepatitis, excluding patients with decompensated liver disease, who either have active disease despite standard of care (Group A), or who are maintained with disease remission using standard of care therapy (Group B). 48 patients will be recruited. Intervention: Weekly sub-cutaneous Belimumab. Duration: 72 weeks with interim analysis after 24 patients have been treated for 24 weeks; target recruitment 48 patients. Evaluation: Safety, Serum liver tests, quality of life, exploratory immunologic biomarkers, optional liver biopsy or fine needle liver aspirate. Primary end-point: Group A: 50% or more of subjects have an ALT<2x ULN & corticosteroids at a dose of </= 5mg of Prednisone (or equivalent); Group B: 50% or more of subjects able to maintain remission (normal ALT, normal IgG) on monotherapy with Belimumab. Conclusion: Using a combination of makers of treatment efficacy and safety the investigator will test the hypothesis that Belimumab should be further formally evaluated for people living with AIH.
Hepatitis C (HCV) HCV antibody assays are the standard of care test used to screen for HCV, but confirmation of acute infection is relegated in the current US guidelines to polymerase chain reaction (PCR) which often takes multiple days and may result in a loss to follow up and treatment, especially in high prevalence populations. HCV core antigen is a new, research use only immunoassay intended for use on the Abbott Alinity i system, an FDA-cleared instrument for clinical chemistry and immunoassay testing. The aim of the study is to evaluate the 48-hour stability of HCV core antigen in fresh serum and plasma specimens collected from individuals with a detectable HCV viral load (HCL VL), as per a recent antibody assay test, under multiple specimen storage conditions mirroring those employed in clinical laboratories.
Chronic hepatitis B (CHB) can lead to hepatocellular carcinoma (HCC), imposing a significant health and economic burden globally. Early detection of hepatitis B virus-related HCC (HBV-HCC) in CHB with potential biomarkers has become a pressing and difficult challenge. Recent advancements in urinary proteomics offer a promising approach for HBV-HCC biomarker identification, utilizing Liquid chromatography with tandem mass spectrometry for urine proteome analysis. Differential analysis using limma in R software will uncover upregulated proteins in HBV-HCC.
Hepatitis C virus (HCV) is a leading cause of morbidity and mortality worldwide. This infection continues to represent a major global public health concern. This is why the introduction of potent antivirals for the treatment of HCV has been one of the major breakthroughs of the current medical era. From a public health perspective, HCV prevalence will be eliminated if the available treatment also targets those most likely to transmit the virus. Despite this scientific advance, a systematic review from the U.S. described that of the 43% of patients aware of their HCV diagnosis, only 16% started treatment. Clearly, the long-known barriers to accessing this treatment must be broken down in order to administer these effective antivirals. The World Health Organization (WHO) has set the ambitious goal of eliminating viral hepatitis as a public health threat by 2030. This goal is really difficult to achieve, especially in low and middle-income countries. Particularly in Argentina, there is a need to improve diagnosis, access to care, and treatment of viral hepatitis. The prospect of viral hepatitis elimination in our country is daunting due to the complexity of the health system and the cost of implementing different strategies. The most pragmatic approach would be to break down national elimination targets into smaller targets for individual populations, for which treatment and prevention interventions can be delivered more quickly and efficiently. This concept is known as micro-elimination. Focusing on micro-elimination of viral hepatitis means working to achieve the WHO target in specific subpopulations. Subpopulations known to have a higher prevalence of HCV infection include prisoners, people who inject drugs, and patients requiring hemodialysis, among others. Currently, patient unawareness of HCV infection represents one of the major barriers to treatment. In many cases, the diagnosis of HCV was established many years ago and patients do not seek treatment probably because they do not recognize the urgency of treating this asymptomatic infection. It is our goal, then, to identify the group of individuals who have been diagnosed with HCV infection but are not currently undergoing regular visits with health care professionals. This strategy is now called re-linking to the medical care of patients with chronic HCV.
This is a controlled study intended to evaluate the usability, label comprehension and performance of the INSTI® HCV Self Test in the hands of untrained lay users using fingerstick blood, with instructions for use specifically designed for a lay person who has not used any hepatitis C rapid self test prior to the study and to assess "lay" users ability to comprehend key concepts and information provided on the outside of the pouch and in the accompanying Instructions for Use. Comprehension will be assessed without product familiarization (demonstration/training) by a healthcare professional.
This is a prospective, multicenter, open-label, non-randomized controlled real-world study to explore the efficacy and safety and to accumulate more evidence-based medical data of an antiviral treatment programme for chronic viral hepatitis B with nonalcoholic fatty liver disease. A total of 1500 patients with chronic hepatitis B complicated with nonalcoholic fatty liver disease are divided into test group (1000 patients receiving PEG-IFNα-based antiviral therapy (combined NAs or Peg-IFNα monotherapy) and control group（500 patients receiving NAs monotherapy） according to their treatment intention. Laboratory and medical data from specified follow-up points are collected, and adverse events and drug combinations are recorded detailly. The primary efficacy indicator is HBsAg clearance at 48 weeks of treatment, and the secondary indicators included: (1) HBsAg clearance at 96 weeks of treatment, (2) Cumulative HBsAg clearance at week 24、120、144、168、192、216 and 240; (3) The improvement of liver function level(ALT, AST, TBIL, etc.), blood lipid (TC, TG, LDL-C, HDL-C, etc.), fasting blood glucose, insulin resistance index (HOMA-IR), controlled attenuation parameter, body mass index , liver stiffness measurement, liver histological fibrosis, FIB-4 index from baseline; (4)Incidence of liver cirrhosis and hepatocellular carcinoma during follow-up. The security assessment includes adverse events, vital signs, and imaging.

A prospective cross-sectional study in which surgically non-invasive sample-taking is done only for the purpose of the study. Capillary (fingerstick) whole blood and EDTA venipuncture whole blood are collected by a healthcare professional. The collected samples of capillary and EDTA whole blood are tested on iStatis and EDTA whole blood sample will be processed to obtain serum and plasma samples to be tested on the iStatis. An aliquot of the collected serum sample will be shipped to the central laboratory for confirmatory testing. The results from iStatis HBsAg Test results will not be used for patient management decisions.
Background: Sudan has a high prevalence of hepatitis B surface antigen (HBsAg), exceeding 8%. The prevalence of hepatitis B varies across different regions of Sudan, ranging from 6.8% in central Sudan to as high as 26% in southern Sudan. Hepatitis B virus (HBV) infection can lead to various complications, including cirrhosis, liver failure, and hepatocellular carcinoma (HCC). Hepatitis D virus (HDV) relies on HBV for replication and can accelerate the progression of HBV-related liver diseases, leading to more severe outcomes. This study aims to determine the prevalence of HDV infection among Sudanese patients with HBV-related liver diseases and to investigate the clinical characteristics of patients with HBV/HDV co-infection. Design/Method: This descriptive cross-sectional hospital-based study was conducted at Ibn Sina Specialized Hospital in Sudan between June and September 2022. Ninety HBV patients aged 16 years and above were included. Patients were interviewed using a structured questionnaire, and medical histories and examinations were recorded. Investigations included liver function tests, abdominal ultrasounds, and ELISA for Ant-HDV-IgG
