Abstract

fetched live from OpenAlex

Abstract Autoimmune hepatitis (AIH) is an organ‐specific autoimmune disease resulting from a loss of immunological tolerance against hepatocyte autoantigens. In the absence of treatment, this disease is fatal. Distinctive characteristics of AIH include hypergammaglobulinemia, presence of autoantibodies and interface hepatitis with lymphoplasmacytic infiltrates. AIH is a rare disease with an estimated point prevalence in Europe and North America of 50–200 cases per million. The pathogenesis of AIH remains unknown. AIH is believed to result from a combination of liver‐specific susceptibility factors, faulty immune tolerance mechanisms (central and peripheral) as well as host and environmental susceptibility factors. Patients respond well to immunosuppressive treatment, but 10–20% of patients are unable to achieve remission using standard treatment. Through a better understanding of AIH pathogenesis as well as cellular(s) and molecular(s) effectors involved, new and effective site‐specific immunotherapies are being developed to induce long‐term remission in patients with minimal deleterious side effects. Key Concepts Autoimmune hepatitis is characterised by a loss of tolerance against hepatocytes leading to the progressive destruction of the hepatic parenchyma. About 70–90% of AIH patients are women. Hallmark characteristics of AIH include hypergammaglobulinemia, presence of autoantibodies and an interface hepatitis with lymphoplasmacytic infiltrates. Type 1 AIH is characterised by the presence of ANA and/or SMA autoantibodies while Type 2 AIH is characterised by the presence of anti‐LKM1 and/or anti‐LC1 autoantibodies. There is a genetic association between AIH and HLA class II genes suggesting a role for CD4+T cells autoimmune response in AIH pathogenesis. Conventional therapy for AIH patients consists of nonspecific immunosuppression, usually through the use of a combination of prednisone/prednisolone and azathioprine. New biologics‐based specific immunotherapies are currently in development and aim to induce long‐term remission with minimal unwanted side effects.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
