The Hepatitic/Cholestatic "Overlap" Syndrome: An Italian Experience
Bibliographic record
Abstract
BACKGROUND: Patients with hepatitic and cholestatic autoimmune liver disease ("overlap syndrome") represent a diagnostic and therapeutic challenge. AIM: To evaluate the prevalence of the "hepatitic/cholestatic overlap" in a large series of consecutive patients with cholestatic autoimmune liver disease. METHODS: We re-evaluated the diagnosis of 235 patients with autoimmune liver disease, including 70 with type 1 autoimmune hepatitis (AIH), 142 with primary biliary cirrhosis (PBC), and 23 with primary sclerosing cholangitis (PSC), using the revised International Autoimmune Hepatitis Group (IAIHG) scoring system. Anti-mitochondrial, anti-nuclear, anti-smooth muscle, anti-liver kidney microsomal type 1, anti-liver cytosol type 1, perinuclear anti-neutrophil nuclear and anti-soluble liver antigen antibodies were evaluated in each patient. RESULTS: Ten patients (3 with a previous diagnosis of PBC and 7 of PSC) scored as "probable" or "definite" AIH. These patients did not have a specific autoantibody profile. CONCLUSIONS: Among patients with PBC, the occurrence of a PBC/AIH overlapping syndrome is rare (2.1%), whereas among patients with PSC an overlap between PSC and AIH is frequent (30.4%). Whether patients with the hepatitic/cholestatic overlap syndrome would benefit from a combination therapy with immunosuppression and ursodeoxycholic acid remains to be established.

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.
