Abstract

An elevated FIB-4 score predicts liver cancer development: A longitudinal analysis from 29,999 patients with NAFLDJournal of HepatologyVol. 76Issue 1PreviewJust recently, the EASL updated their “Clinical Practice Guidelines on non-invasive tests for evaluation of liver disease severity and prognosis”, emphasizing the high predictive value and clinical relevance of simple non-invasive tests (NITs), such as the fibrosis-4 (FIB-4) score (calculated on the basis of age, AST/ALT levels and platelet count1) to rule out advanced fibrosis and stratify the risk of liver-related outcomes in patients with non-alcoholic fatty liver disease (NAFLD).2 A higher FiB-4 score should trigger referral to a specialized hepatologist and justify initiation of further hepatological and metabolic work-up as well as potentially therapeutic interventions and regular surveillance. Full-Text PDF EASL Clinical Practice Guidelines on non-invasive tests for evaluation of liver disease severity and prognosis – 2021 updateJournal of HepatologyVol. 75Issue 3PreviewNon-invasive tests are increasingly being used to improve the diagnosis and prognostication of chronic liver diseases across aetiologies. Herein, we provide the latest update to the EASL Clinical Practice Guidelines on the use of non-invasive tests for the evaluation of liver disease severity and prognosis, focusing on the topics for which relevant evidence has been published in the last 5 years. Full-Text PDF Poor performance of FIB-4 in elderly individuals at risk for chronic liver disease – implications for the clinical utility of the EASL NIT guidelineJournal of HepatologyVol. 76Issue 1PreviewWith the identification of novel risk factors for chronic liver disease, the number of patients potentially eligible for referral for hepatologist consultation has expanded rapidly. Hence, non-invasive tools for risk stratification and identification of patients at highest risk are essential. We, therefore, read with great interest the 2021 update of the “EASL Clinical Practice Guidelines on non-invasive tests for evaluation of liver disease severity and prognosis”.1 Through the synthesis of available evidence and expert opinion, an algorithm was constructed to aid practitioners in identifying patients at highest risk of significant liver disease. Full-Text PDF Risk stratification of decompensation using liver stiffness and platelet counts in compensated advanced chronic liver disease (CHESS2102)Journal of HepatologyVol. 76Issue 1PreviewThe latest EASL guidelines on non-invasive tests for the evaluation of liver disease severity and prognosis proposed an algorithm for risk stratification in compensated chronic liver disease (CLD) using non-invasive tools.1 Patients with liver stiffness measurement (LSM) <20 kPa and platelet counts (PLT) >150 ×109/L are very unlikely to have varices needing treatment, while those not meeting this criteria are at an increased risk of clinical decompensation.1 LSM is the most validated non-invasive tool for risk stratification in CLD and a cut-off >20-25 kPa could be used to identify patients with clinically significant portal hypertension,2,3 which is closely associated with decompensation in patients with CLD.

In their study, FIB-4 had poor discriminative performance (AUROC 0.635) and missed 40/159 (25.2%) individuals above the age of 65 with LSM ≥8 kPa. The Rotterdam study is a large cohort sampled from a general, unselected population, with available data on liver biochemistry, metabolic syndrome, alcohol consumption, and LSM, and included 3,891 participants of whom 6.0% had LSM ≥8 kPa. However, the study has several drawbacks that we would like to underline. First, and most important, LSM is better at ruling-out rather than ruling-in advanced liver fibrosis, and an LSM ≥8 kPa does not necessarily imply the presence of advanced fibrosis, especially in a random population sample. LSM has suboptimal specificity and positive predictive value (PPV), even more in a context of low prevalence of advanced fibrosis (please see our considerations on the dependency of sensitivity, specificity, PPV and negative predictive value on the prevalence of a given endpoint of interest in the general population in our CPGs[4]European Association for the Study of the Liver. et al.European Association for the Study of the Liver- CPG PanelEASL Clinical Practice Guidelines on non-invasive tests for evaluation of liver disease severity and prognosis – 2021 update.J Hepatol. 2021 Sep; 75: 659-689Abstract Full Text Full Text PDF PubMed Scopus (195) Google Scholar). Several patients with FIB-4 <1.30 and LSM ≥8.0 kPa would likely not have advanced fibrosis, which leads to an underestimation of the sensitivity of FIB-4 for advanced fibrosis in this work. Indicatively, the specificity of the 8 kPa cut-off for advanced fibrosis in patients with alcohol-related liver disease or NAFLD was 64% in a large multicenter cohort.[6]Papatheodoridi M.

Longitudinal studies performed in the general population, similar to the Rotterdam cohort, have shown that the prognosis of patients with FIB-4 <1.30 is excellent and, even more, that repeating FIB-4 can refine the prognosis during follow-up.[7]Hagström H.

Second, performing a FIB-4 examination is indicated in any patient who has risk factors for advanced fibrosis in the context of NAFLD or alcohol-related liver disease rather than in unselected populations. Finally, performing FIB-4 in individuals ≥65 years old is somehow an artificial exercise – many patients would not benefit because of comorbidities and competing risks of mortality.Irrespective of these considerations, in an ideal world, patients with risk factors for chronic liver disease should be evaluated using the best available non-invasive methods for liver fibrosis assessment. We acknowledge that FIB-4 is limited by false negatives and false positives. Future referral pathways and screening programs will have to evolve, for instance taking advantage of the increased availability of point- and 2D-shear wave ultrasound elastography embedded in most high-end ultrasound devices, or of the broader availability of patented serum tests of fibrosis with high accuracy. Until then, we maintain that FIB-4 is the recommended first-line test in current referral pathways due to a good balance between simplicity, availability, price, and a diagnostic accuracy that beats individual routine blood tests and doctor’s clinical acumen alone.[9]Lindvig K.P.
