Autoimmune hepatitis in a demographically isolated area of Australia
Bibliographic record
Abstract
BACKGROUND: Previous studies describing autoimmune hepatitis (AIH) come from liver transplant centres in which a skewed distribution of cases may give a misleading picture of the incidence of AIH and its natural history. This series describes AIH in a stable and demographically discrete population of patients in the Australian Capital Territory (ACT) and the surrounding region. METHODS: In 42 patients with type 1 AIH (point prevalence 8 per 100,000 population), clinical, laboratory and histological features at presentation, response to initial therapy, details of maintenance therapy and outcome were recorded. RESULTS: Consistent with other publications, the male-to-female ratio was 1:3, mean age at presentation was 53 years and 24% had cirrhosis at diagnosis. Most patients (86%) responded to initial therapy and 67% went into long-term remission. One patient died from liver failure and none required liver transplantation. Azathioprine was included in the treatment regimen in 74% of cases with doses generally <2 mg/kg. Azathioprine dose greater than or equal to 2 mg/kg was associated with better clinical outcome, but this did not reach statistical significance. A higher proportion of female patients had cirrhosis at presentation (9/10 vs 1/10; P= 0.24). CONCLUSION: In this Australian community-based study, type 1 AIH was primarily a disease of later life, responded to conventional immunosuppressive therapy and generally has a good prognosis. Further study of the use of azathioprine is warranted to determine the optimal dose.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
