Effect of S-Adenosyl-L-Methionine on Liver Biochemistry and Quality of Life in Patients with Primary Biliary Cholangitis Treated with Ursodeoxycholic Acid. A Prospective, Open Label Pilot Study
Bibliographic record
Abstract
BACKGROUND AND AIMS: Chronic liver disease induces an acquired deficiency of S-adenosyl-L-methionine (SAMe) leading to impairment of detoxifying processes in the liver. Ursodeoxycholic acid (UDCA) represents the standard treatment in primary biliary cholangitis (PBC). As both compounds exert their hepatoprotective effects by different mechanisms, it is conceivable that when used together their effect might be additive. The aim of this study was to analyse the effect of SAMe supplementation on liver biochemistry and health-related quality of life (HRQoL) in patients with PBC, treated with UDCA. METHODS: In this prospective pilot, proof of the principle, non-randomized and open label study we enrolled 24 patients with PBC treated with UDCA for at least 6 months. They had received both UDCA in a standard dose of 13-15 mg/kg b.w. and SAMe in the dose of 1200 mg daily over a period of 6 months. A group of 24 patients with PBC treated with UDCA served as control for liver biochemistry (Study registered on the platform ClinicalTrials.gov under ID: NCT02557360). RESULTS: We observed a significant decrease of ALP, GGT and total cholesterol in non-cirrhotic patients treated with SAMe. There was also a significant improvement of fatigue and pruritus in PBC-40 questionnaire and amelioration of anxiety in STAI 2 questionnaire in the SAMe group. Treatment with SAMe neither increased sulfation capacity of the liver nor had an effect on fibroblast growth factor-19 serum levels. CONCLUSIONS: Our pilot study demonstrates a positive effect of adding SAMe to UDCA in non-cirrhotic patients with PBC.

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.
