Evolution of autoimmune hepatitis to primary sclerosing cholangitis: A sequential syndrome
Bibliographic record
Abstract
Recently, the autoimmune hepatitis (AIH)/primary sclerosing cholangitis (PSC) overlap syndrome has been reported increasingly. In this syndrome, patients present with features of both AIH and PSC. It has been suggested that the 2 diseases may be sequential in their occurrence, whereby patients have features of AIH and then after a number of years develop features of PSC, but clear confirmation of evolution has not been documented in adults. We describe 6 adult cases in which PSC was diagnosed many years after well-established AIH. Six patients are described in whom AIH definitely was diagnosed at presentation. No evidence of biliary disease was noted on the initial liver biopsy or endoscopic retrograde cholangiography (ERCP). All patients responded well to immunosuppressive therapy. After an average duration of follow-up of 4.6 years they became resistant to immunosuppression, and developed clear features of PSC, which was confirmed by ERCP in all patients. The average age of the patients at first presentation was 31.3 years, 2 were women and 4 were men, and 3 had ulcerative colitis. We found no specific features at presentation that could predict this evolutionary outcome. In conclusion, patients with well-established AIH can, after variable duration of follow-up, develop PSC. In patients with AIH who become resistant to immunosuppression or develop significant cholestasis, PSC should be ruled out by ERCP.

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.
