Abstract

There is a need to determine biomarkers reflecting disease activity and prognosis in primary sclerosing cholangitis (PSC). We evaluated the prognostic utility of the enhanced liver fibrosis (ELF) score in Norwegian PSC patients. Serum samples were available from 305 well‐characterized large‐duct PSC patients, 96 ulcerative colitis patients, and 100 healthy controls. The PSC patients constituted a derivation panel (recruited 1992‐2006 [n = 167]; median age 41 years, 74% male) and a validation panel (recruited 2008‐2012 [n = 138]; median age 40 years, 78% male). We used commercial kits to analyze serum levels of hyaluronic acid, tissue inhibitor of metalloproteinases‐1, and propeptide of type III procollagen and calculated ELF scores by the previously published algorithm. Results were also validated by analysis of ELF tests using the ADVIA Centaur XP system and its commercially available reagents. We found that PSC patients stratified by ELF score tertiles exhibited significantly different transplant‐free survival in both panels ( P < 0.001), with higher scores associated with shorter survival, which was confirmed in the validation panel stratified by ELF test tertiles ( P = 0.003). The ELF test distinguished between mild and severe disease defined by clinical outcome (transplantation or death) with an area under the curve of 0.81 (95% confidence interval [CI] 0.73‐0.87) and optimal cutoff of 10.6 (sensitivity 70.2%, specificity 79.1%). In multivariate Cox regression analysis in both panels, ELF score (hazard ratio = 1.9, 95% CI 1.4‐2.5, and 1.5, 95% CI 1.1‐2.1, respectively) was associated with transplant‐free survival independently of the Mayo risk score (hazard ratio = 1.3, 95% CI 1.1‐1.6, and 1.6, 95% CI 1.2‐2.1, respectively). The ELF test correlated with ultrasound elastography in separate assessments. Conclusion : The ELF score is a potent prognostic marker in PSC, independent of the Mayo risk score.

  • The ELF test can predict transplant-free survival in PSC and retains predictive value longitudinally despite dynamic fluctuations in the course of PSC with regard to progression to cirrhosis, but without association between reduced values and improved outcome.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
