| 6 | Performance of the Enhanced Liver Fibrosis Score,Comparison with Vibration-controlled Transient Elastography Data,and Development of a Simple Algorithm to Predict Significant Liver Fibrosis in a Community-based Liver Service:A Retrospective Evaluation显示文摘Background and Aims:Liver fibrosis is a key risk factor for cirrhosis,hepatocellular carcinoma and end stage liver failure.The National Institute for Health and Care Excellence guidelines for assessment for advanced(≥F3)liver fibrosis in people with nonalcoholic fatty liver disease recommend the use of enhanced liver fibrosis(ELF)test,followed by vibration-controlled transient elastography(VCTE).Performance of ELF at predicting significant(≥F2)fibrosis in real-world practice is uncertain.To assess the accuracy of ELF using VCTE;investigate the optimum ELF cutoff value to identify≥F2and≥F3;and develop a simple algorithm,with and without ELF score,for detecting≥F2.Methods:Retrospective evaluation of patients referred to a Community Liver Service for VCTE,Jan-Dec 2020.Assessment included:body mass index(BMI),diabetes status,alanine aminotransferase(ALT)levels,ELF score and biopsy-validated fibrosis stages according to VCTE.Results:Data from 273 patients were available.n=110 patients had diabetes.ELF showed fair performance for≥F2 and≥F3,area under the curve(AUC)=0.70,95%confidence interval(CI)0.64-0.76 and AUC=0.72,95%CI:0.65-0.79 respectively.For≥F2 Youden's index for ELF=9.85 and for≥F3,ELF=9.95.Combining ALT,BMI,and HbA1c(ALBA algorithm)to predict≥F2 showed good performance(AUC=0.80,95%CI:0.69-0.92),adding ALBA to ELF improved performance(AUC=0.82,95%CI:0.77-0.88).Results were independently validated.Conclusions:Optimal ELF cutoff for≥F2 is 9.85 and 9.95 for≥F3.ALT,BMI,and HbA1c(ALBA algorithm)can stratify patients at risk of≥F2.ELFperformance is improved by adding ALBA. | Tina Reinson Janisha Patel Mead Mathews Derek Fountain Ryan M.Buchanan Christopher DByrne | 2023 | Journal of Clinical and Translational Hepatology2023，11，4： | 0 |
