There is a significant unmet need for safe and effective therapeutic approaches to prevent immune-mediated graft injury and its complications in liver transplant (LT) recipients with autoimmune liver disease (AILD) including autoimmune hepatitis and primary sclerosing cholangitis. Siplizumab is an anti-cluster of differentiation 2 (CD2) monoclonal antibody that has demonstrated a favorable safety profile of siplizumab in over 779 human subjects and has been shown to target memory T cells-a key driver in the immune processes surrounding rejection and autoimmunity post LT in AILD. The purpose of this pilot, open-label phase 1 study is to determine the safety of siplizumab for induction in patients with AILD undergoing LT. Up to eight (8) subjects will receive siplizumab 0.6 mg/kg/dose on the day of transplant (Day 0) and Day 4 post-transplant, for a total of two doses. All subjects will be followed in the study for 12 months post-LT.

The investigators identified polyreactive immunoglobulin G (pIgG) in adults (published in Hepatology: https://doi.org/10.1002/hep.32134) and children (in preparation). Quantification of these pIgG using a "home-made" ELISA facilitates the diagnosis of autoimmune hepatitis (AIH) as compared to non-AIH liver diseases and healthy controls. Positivity for pIgG was independent from ANA/SMA positivity and equally diagnostic for AIH even when conventional autoantibodies (ANA/SMA/SLA/LKM) were negative. Additionally, the frequency of pIgG was lower than conventional autoantibodies (ANA, SMA) in vaccinia/drug associated severe liver injury in a retrospective multicenter study after Covid-19 vaccination (https://doi.org/10.1016/j.jhepr.2022.100605). Aims of the study The study aims to evaluate the diagnostic capacity of pIgG to predict AIH in comparison to other liver diseases prospectively. To avoid diagnostic inaccuracy between AIH with long-term need for an immunosuppression and drug induced liver injury with autoimmune features, which can be indistinguishable from AIH at baseline and which has a very low relapse rate after a short steroid course, a follow-up after six months is obligatory for inclusion. Therefore, the investigators will collect one serum sample from every patient (without immunosuppressive treatment) that presents to the respective hospital for evaluation of liver disease by liver biopsy within one year after initiation of the study and that provided written informed consent. Follow-up for evaluation of steroid dependency at six months after diagnosis is obligatory.
NCT04028869
This study was a retrospective clinical observation cohort study. All patients with autoimmune liver disease treated with glycyrrhizic acid preparations in the Department of Liver Diseases, Department of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, were enrolled. Clinical follow-up data including demographics, hematuria, and liver and kidney were collected. Functional, electrolyte blood glucose, PTA, erythrocyte sedimentation rate, serum AFP and other clinical biochemical indicators and autoantibodies, special proteins and liver imaging (liver ultrasound) examination. The clinical effect of glycyrrhizic acid preparation for the treatment of autoimmune liver disease for 144 weeks and the safety during treatment were analyzed.
