Clinical characteristics and corticosteroid therapy in patients with autoimmune-hepatitis-induced liver failure
Bibliographic record
Abstract
AIM: To investigate the clinical features, response to corticosteroids, and prognosis of autoimmune hepatitis (AIH)-induced liver failure in China. METHODS: A total of 22 patients (19 female and 3 male; average age 51 ± 15 years) with AIH-induced liver failure treated in our hospital from 2004 to 2012 were retrospectively analyzed. Clinical, biochemical and pathological characteristics of the 22 patients and responses to corticosteroid treatment in seven patients were examined retrospectively. The patients were divided into survivor and non-survivor groups, and the clinical characteristics and prognosis were compared between the two groups. The t test was used for data analysis of all categorical variables, and overall survival was calculated by the Kaplan-Meier method. RESULTS: At the time of diagnosis, mean IgG was 2473 ± 983 mg/dL, with three (18.8%) patients showing normal levels. All of the patients had elevated serum levels of antinuclear antibody (≥ 1:640). Liver histology from one patient showed diagnostic pathological changes, including massive necrosis and plasma cell infiltration. Four patients survived (18.2%) and 18 died (81.8%) without liver transplantation. The results showed that patients with low admission Model for End-Stage Liver Disease (MELD) scores (21.50 ± 2.08 vs 30.61 ± 6.70, P < 0.05) and corticosteroid therapy (100% vs 16.7%, P < 0.05) had better prognosis. A total of seven patients received corticosteroid therapy, of whom, four responded and survived, and the other three died. Survivors showed young age, shorter duration from diagnosis to corticosteroid therapy, low MELD score, and absence of hepatic encephalopathy at the time of corticosteroid administration. Six patients who were administered corticosteroids acquired fungal infections but recovered after antifungal therapy. CONCLUSION: Early diagnosis and corticosteroid therapy are essential for improving the prognosis of patients with AIH-induced liver failure without liver transplantation.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
