Trends in Primary Biliary Cholangitis: Prospective Cohort Study From the European Reference Network Registry (R‐LIVER)
Bibliographic record
Abstract
BACKGROUND AND AIMS: The European Reference Network on Hepatological Diseases (ERN RARE-LIVER) is a Europe-wide network for centers of excellence in the management of rare liver diseases. We aimed to evaluate the current diagnostic and therapeutic trends of primary biliary cholangitis (PBC). METHODS: Prospective data of PBC cases diagnosed from 2017 to March 2024 were extracted from the R-LIVER registry of ERN-RARE LIVER. Cases without two follow-ups within 24 months were excluded from the treatment analysis. Biochemical response according to Toronto criteria and normalization of alkaline phosphatase (ALP) values after 12 months of Ursodeoxycholic Acid (UDCA) were evaluated. RESULTS: This study included 327 incident cases from six centers. Median age was 56 years, 89.3% were female. At the time of diagnosis, median values of ALP were 1.37 x ULN, and median bilirubin was 0.49 x ULN. Transient elastography (TE) was performed in 230 patients (70.3%) at baseline; median liver stiffness was 6.2 kPa. Out of 316 subjects, treatment with UDCA was started in 312 patients (98.7%); 246 (85.1%) achieved ALP values < 1.67 x ULN at 12 months. Normalization of ALP values occurred in 143 subjects (49.5%) at 12 months. Among 43 patients with inadequate response, 18 (41.9%) were treated with second-line therapies, and had worse liver biochemistry at baseline. CONCLUSION: In the current era, patients with PBC are diagnosed at an early stage using non-invasive methods and are almost all treated with UDCA. The biochemical response rate is 85.1%, but the use of second-line therapies for inadequate responders remains suboptimal.

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.
