In plain words

What the trial is, and whether it could suit you

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
