Filter by:The primary aim of this study is to investigate whether the baseline cT1 can predict those whose condition relapses following treatment withdrawal. The secondary aim is to investigate correlation of cT1 with histology to explore utility as a monitoring tool. A total of 97 patients with AIH will be recruited and divided into 2 arms. 20 of which will be treatment naive and the other 77 will have been on treatment for the past 18-24 months and will be coming in for therapy cessation review.
The purpose of this study is to compare the pharmacokinetics of JKB-122 tablets with JKB-122 capsules in healthy male subjects subjects.
Autoimmune hepatitis (AIH) is an immune-mediated and inflammatory liver disorder. It is currently divided into types 1 and 2, differentiated and defined by the presence of specific autoantibodies. The objectives are to describe the prevalence and incidence of type 1 and 2 autoimmune hepatitis and to analyze the clinics, biochemical and histopathological profiles at diagnosis and follow-up, initial therapy, response to therapy and long-term follow-up in three Italian centers of patients with type 1 and type 2 AIH.
The purpose of this study is to evaluate whether Orencia® (Abatacept) improves outcomes in liver transplant patients with recurrent or de novo AIH (autoimmune hepatitis) that has not responded to previous therapy. AIH that does not respond to steroids or conventional immunotherapy often affects young patients and leads to irreversible liver damage. There is currently no effective therapy for this condition.
Subjects with stable autoimmune hepatitis disease currently being administered corticosteroids with or without azathioprine (AZA) treatment will be be treated with Cannabidiol instead of standard of care treatment with corticosteroids
This 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.
This study evaluates the effect of erythropoietin on the number and function of regulatory T cells in adults with autoimmune hepatitis. Participants will receive a single dose of erythropoietin, and then the investigators will collect blood at different time points for analysis of regulatory T cell number and function.
This study aims to prospectively assess the repeatability and reproducibility of iron-corrected T1 (cT1), T2*, and hepatic proton density fat fraction (PDFF) quantification with multiparametric MRI using the LiverMultiScan™ (LMS, Perspectum Diagnostics, Oxford, UK) protocol across different field strengths, scanner manufacturers and models.
Autoimmune hepatitis (AIH) is an inflammatory, chronic and recurrent liver disease of unknown etiology that can lead to cirrhosis or acute liver failure. It is a rare disease affecting 16 cases every 100,000 persons in Europe, mainly in women in every age group. It is characteristic the presence of high levels of aminotransferases, hypergammaglobulinemia and high titres of autoantibodies, as well as interface hepatitis in the biopsy. Due to the autoimmune etiology of AIH, treatment is based on immunosuppressive strategies, mainly prednisone and azathioprine regimens which make possible to achieve remission in approximately 75% of cases with moderate or severe hepatocellular inflammation. Remission is defined as a normalization in aminotransferases, immunoglobulin G (IgG) and resolution histological inflammation (this last one comes after biochemical remission). It has also been observed that there is a restoration in number and function of Tregs after achieving remission. The rates of recurrence after withdrawing it varies from 30-87% depending on the studies and their follow-up. It is usual to maintain treatment indefinitely in clinical practice. This strategy implies maintaining treatment for long periods of time in patients that could be available to maintain sustained remission, exposing them to adverse effects. From all these, we think it is important to be able to identify patients who will be able to maintain biochemical and histological remission without immunosuppression (IS), which still is not known in this disease's management. Some observational and retrospective studies have identified some parameters that could imply a higher risk of recurrence after stopping treatment such as high levels of aminotransferases and IgG, less time of remission before withdrawal (specifically less than 2 years) or presence of interface hepatitis in a biopsy prior discontinuation of treatment. However, the accuracy of these parameters is low and as a result, management of this disease has not changed much over the past decades, still having patients under prolonged treatment unnecessarily. For the previously mentioned reasons, there is a need to identify new biomarkers that allow clinicians selecting patients with AIH in whom treatment could be stopped avoiding its costs and adverse effects. At the same time, it would help to understand the immunopathogenesis of AIH and identification of new therapeutic targets.
CaNAL is a longitudinal observational cohort study of patients diagnosed with Primary Biliary Cholangitis (PBC), Autoimmune Hepatitis (AIH), or overlap syndrome. This study creates a nationwide registry and network focusing on high quality long-term follow-up of individual patient data from major Canadian centers. Primary Biliary Cholangitis (PBC) and Autoimmune Hepatitis (AIH) are rare and slowly progressive liver diseases associated with development of cirrhosis, liver cancer (HCC) and liver failure requiring liver transplantation or leading to premature death. The rarity and slowly progressive nature of these autoimmune liver diseases make them difficult to study and only a large scale approach combining patient data from multiple centers across Canada will allow new insights. The primary aim of the Canadian Network for Autoimmune Liver Disease is to build a Canadian registry of patients with PBC, AIH, and overlap syndrome. We capture patient characteristics, laboratory assessments and natural history, patient-reported outcomes including quality of life measures and environmental exposures, response to treatment, and pre- and post-transplant outcomes. We will then identify risk factors associated with critical outcomes for the patient, including response to treatment, progression to transplant, risk of liver cancer, and recurrent disease after transplant. We can identify biomarkers (biochemical indicators of progression of disease) to help diagnose autoimmune liver disease at its earliest stages, ensuring timely treatment and preventing disease progression. CaNAL will provide a better understanding of autoimmune liver diseases, biomarkers predictive of disease progression or non-response to therapy as well as better knowledge of the etiology and pathogenesis. CaNAL will also help to serve as a platform for conducting clinical trials or targeted lab-studies to answer important questions that are unlikely to be evaluated by the pharmaceutical industry.
