AGILE 3+ Score for the Diagnosis of Advanced Fibrosis and for Predicting Liver-related Events in NAFLD.

BACKGROUND & AIMS: We aimed to assess the diagnostic accuracy of AGILE 3+, a recently developed score based on the combination of aspartate aminotransferase/alanine aminotransferase ratio, platelet count, diabetes status, sex, age, and liver stiffness measurement (LSM) by transient elastography, when compared with Fibrosis-4 (FIB-4) and LSM, for the diagnosis of advanced fibrosis and for the prediction of liver-related events (LREs) occurrence in patients with NAFLD. METHODS: A total of 614 consecutive patients with biopsy-proven NAFLD or clinical diagnosis of NAFLD-related compensated cirrhosis were enrolled. LREs were recorded during follow-up. FIB-4, LSM by transient elastography (FibroScan device), and AGILE 3+ were measured. The diagnostic performance of noninvasive criteria for advanced fibrosis and for the prediction of LREs was assessed using the area under the receiver operating characteristic curve (AUROC) and decision curve analysis. RESULTS: In patients with biopsy-proven NAFLD (n = 520), LSM and AGILE 3+ had higher AUROC than FIB-4 (0.88 for LSM and AGILE 3+ vs 0.78 for FIB-4; P < .001) for advanced fibrosis, and AGILE 3+ exhibited a smaller indeterminate area in the test (25.2% for FIB-4 vs 13.1% for LSM vs 8.3% for AGILE 3+). Within the entire cohort of patients, AGILE 3+ had significantly higher AUROC for predicting LREs with respect to LSM (AUROC 36 months 0.95 vs 0.93; P =.008; 60 months 0.95 vs 0.92; P = .006; 96 months 0.97 vs 0.95; P = .001). Decision curve analysis showed that all scores had modest net benefit for ruling-out advanced fibrosis at the risk threshold of 5% to 10% where advanced fibrosis was absent. At the risk threshold of 5% of false negatives or false positives in LRE at 36, 60, 96, and 120 months, AGILE 3+ outperformed both FIB-4 and LSM for ruling out LRE. CONCLUSIONS: Depending on resource availability, clinical setting, and the risk scenarios, AGILE 3+ is an accurate and valid alternative to FIB-4 and LSM for the noninvasive assessment of disease severity and prognosis in patients with NAFLD.

RESIST-HCV Criteria to Monitor Progression of Low-Risk Esophageal Varices in Patients With Compensated Cirrhosis After HCV Eradication: The SIMPLE Study: SIMPLE: Scoring Index to Monitor Progression of Low-risk Esophageal varices.

INTRODUCTION: Noninvasive criteria to predict the progression of low-risk esophageal varices (EV) in patients with compensated hepatitis C virus (HCV) cirrhosis after sustained virological response (SVR) by direct-acting antivirals (DAAs) are lacking. Our aim was to assess the diagnostic performance of Rete Sicilia Selezione Terapia-HCV (RESIST-HCV) criteria for EV progression compared with elastography-based criteria (Baveno VI, Expanded Baveno VI, and Baveno VII-HCV criteria). METHODS: All consecutive patients observed at 3 referral centers with compensated HCV cirrhosis with or without F1 EV who achieved sustained virological response by DAAs were classified at last esophagogastroduodenoscopy (EGDS) as RESIST-HCV low risk (i.e., low probability of high-risk varices [HRV]) if platelets were >120 × 10 9 /L and serum albumin >3.6 g/dL or RESIST-HCV high risk (i.e., high probability of HRV) if platelets were <120 × 10 9 /L or serum albumin <3.6 g/dL. The primary outcome was the progression to HRV. The area under the receiver operating characteristic curve and decision curve analysis of noninvasive criteria were calculated. RESULTS: The cohort consisted of 353 patients in Child-Pugh class A (mean age 67.2 years, 53.8% males). During a mean follow-up of 44.2 months, 34 patients (9.6%, 95% CI 6.7%-13.5%) developed HRV. At the last EGDS, 178 patients (50.4%) were RESIST-low risk, and 175 (49.6%) were RESIST-high risk. RESIST-HCV criteria showed the highest area under the receiver operating characteristic curve (0.70, 95% confidence interval 0.65-0.75), correctly sparing the highest number of EGDS (54.3%), with the lowest false-positive rate (45.7%), compared with elastography-based criteria. Decision curve analysis showed that RESIST-HCV had higher clinical utility than elastography-based criteria. DISCUSSION: Biochemical-based RESIST-HCV criteria are useful to easily predict HRV development after HCV eradication by DAAs in patients with compensated cirrhosis and low-risk EV.
