Background The prognostic role of the fibrosis-4 (FIB-4) index relative to intrahepatic cholangiocarcinoma (ICC) after hepatectomy remains unclear. This study sought to characterize the impact of the FIB-4 index and tumor burden score (TBS) on recurrence and overall survival (OS). Methods ICC patients undergoing hepatectomy (2000–2020) were identified using a multi-institutional database. Patients were categorized as low (low TBS/low FIB-4 index), intermediate (low TBS/high FIB-4 index or high TBS/low FIB-4 index), and high (high TBS/high FIB-4 index). Results Among 1168 patients in different TBS and FIB-4 index cohorts, 3-year recurrence varied considerably. For instance, among the patients with low TBS, individuals with a high FIB-4 index had a greater risk of recurrence than patients with a low FIB-4 index (59.9 vs. 47.7%; P  = 0.01). Among patients with a high TBS, individuals with a high versus a low FIB-4 index had a higher incidence of recurrence (76.8 vs. 69.0%; P  = 0.04). A similar pattern was observed among patients with both a low FIB-4 index (low [47.7%] vs. high [69.0%] TBS) and a high FIB-4 index (low [59.9%] vs. high [76.8%] TBS; both P  < 0.001). Patients with a high [27.5%] versus a low [48.8%] TBS; P  < 0.001) and patients with a high [34.2%] versus a low [43.5%] FIB-4 index; P  = 0.01) had a worse OS. The multivariable analysis demonstrated an increasing risk of recurrence in the intermediate-index (hazard ratio [HR], 1.61; 95% confidence interval [CI], 1.20–2.16; P  = 0.001) and high-index (HR, 2.13; 95% CI 1.45–3.13; P  < 0.001) groups versus the low-index group. Conclusions Both tumor-related and non-tumorous characteristics should be used to predict risk of recurrence and survival more accurately among patients with ICC following hepatic resection.

Post-hepatectomy liver failure (PHLF) is a potentially life-threatening complication following liver resection. Hepatocellular carcinoma (HCC) often occurs in patients with chronic liver disease, which increases the risk of PHLF. This study aimed to investigate the ability of the combination of liver function and fibrosis markers (ALBI score and FIB-4 index) to predict PHLF in patients with HCC. Patients who underwent hepatectomy for HCC between August 2012 and September 2022 were considered for inclusion. Multivariable logistic regression analysis was used to identify factors associated with PHLF, and ALBI score and FIB-4 index were combined based on their regression coefficients. The performance of the combined ALBI-FIB4 score in predicting PHLF and postoperative mortality was compared with Child–Pugh score, MELD score, ALBI score, and FIB-4 index. A total of 215 patients were enrolled in this study. PHLF occurred in 35 patients (16.3%). The incidence of severe PHLF (grade B and grade C PHLF) was 9.3%. Postoperative 90‐d mortality was 2.8%. ALBI score, FIB-4 index, prothrombin time, and extent of liver resection were identified as independent factors for predicting PHLF. The AUC of the ALBI-FIB4 score in predicting PHLF was 0.783(95% CI : 0.694–0.872), higher than other models. The ALBI-FIB4 score could divide patients into two risk groups based on a cut-off value of − 1.82. High-risk patients had a high incidence of PHLF of 39.1%, while PHLF just occurred in 6.6% of low-risk patients. Similarly, the AUCs of the ALBI-FIB4 score in predicting severe PHLF and postoperative 90-d mortality were also higher than other models. Preoperative ALBI-FIB4 score showed good performance in predicting PHLF and postoperative mortality in patients undergoing hepatectomy for HCC, superior to the currently commonly used liver function and fibrosis scoring systems.

Background Metabolic-associated fatty liver disease (MAFLD), one of the most common liver diseases, is detected in patients with concomitant hepatic steatosis and Type 2 Diabetes (T2D). We looked into the relationship between Fibrosis-4 (FIB-4) index and coronary artery diseases (CAD) in patients with MAFLD, to further look into the efficiency of FIB-4 in screening for CAD among patients with MAFLD. Method In this study, we included 1664 patients with MAFLD (T2D, who also had hepatic steatosis) during 2012–2022 and divided them into 2 groups; CAD and non-CAD. Demographic, Anthropometric indices, liver function tests, lipid profile and FIB-4 index of all patients were evaluated and compared. Result Among the 1644 patients (all have MAFLD), 364(21.4%) had CAD. Patients with MAFLD and CAD were more probable to be hypertensive, have longer duration of diabetes and be older (with p-values < 0.001). After adjustment for confounding factors, in a multivariable logistic regression model, FIB4 showed a significant independent relationship with concomitant MAFLD and CAD. Upper Tertile FIB-4 had an odds ratio of 3.28 (P-value = 0.002) to predict CAD. Furthermore, in Receiver Operating Characteristic (ROC) Curve analysis with the maximum Youden Index, a FIB-4 cut-off of 0.85 (AUC = 0.656, 95% CI 0.618–0.693, P < 0.001) noted to predict CAD in patients with MAFLD. Conclusion This study showed that the FIB-4 score independently correlates with CAD in patients with MAFLD.

BackgroundWhile achieving sustained virological response (SVR) following interferon-based or direct-acting antiviral agent (DAA) treatments reduces the incidence of hepatocellular carcinoma (HCC), an increase in unexpected early occurrence or recurrence of HCC after hepatitis C virus elimination by DAA treatments has been reported. We prospectively investigated the incidence and risk factors of HCC after DAA treatment in a large multicenter cohort in Japan.MethodsPatients with chronic hepatitis C with or without cirrhosis who were treated with DAAs and obtained SVR were enrolled. DAAs were administered for 3 or 6 months. A total of 2552 patients were enrolled.ResultsOf these, 70 patients (2.7%) developed HCC. The 12-, 24-, and 36-month cumulative HCC incidences were 1.3%, 2.9%, and 4.9% in all patients; 2.5%, 5.2%, and 10.0% in those with cirrhosis; and 0.9%, 2.1%, and 2.9% in those without cirrhosis, respectively. Multivariate analysis revealed age, sex, gamma-glutamyl transpeptidase level, and fibrosis-4 index to be independent factors associated with HCC. Patients with these four factors had an approximately six-to-sevenfold increased risk for HCC development. Five patients with large and early tumor occurrence did not receive contrast imaging examinations before treatment.ConclusionAlthough the results of our prospective study suggested that achieving SVR by DAA treatment reduces the incidence of HCC, HCC development still occurs. Careful follow-up is important in patients with risk factors.

Background/Objectives: Cystic fibrosis-associated liver disease (CFLD) is a significant complication in individuals with cystic fibrosis (CF), contributing to morbidity and mortality, with no universally accepted, reliable, non-invasive diagnostic tool for early detection. Current diagnostic methods, including liver biopsy and imaging, remain resource-intensive and invasive. Non-invasive biomarkers like the Fibrosis-4 (FIB-4) index have shown promise in diagnosing liver fibrosis in various chronic liver diseases. This study explores the potential of the FIB-4 index to predict CFLD in an adult CF population and assesses its correlation with transient elastography (TE) as a potential diagnostic tool. The aim of this study is to evaluate the diagnostic performance of the FIB-4 index for CFLD in adults with CF and investigate its relationship with TE-based liver stiffness measurements (LSM). Methods: The study was conducted in a regional cystic fibrosis unit, including 261 adult CF patients. FIB-4 scores were calculated using an online tool (mdcalc.com) based on patient age, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and platelet count. In parallel, 29 patients underwent liver stiffness measurement using TE (Fibroscan®). Statistical analyses included non-parametric tests for group comparisons and Pearson’s correlation to assess the relationship between FIB-4 scores and TE results. Results: The mean FIB-4 score in patients diagnosed with CFLD was higher (0.99 ± 0.83) compared to those without CFLD (0.64 ± 0.38), although the difference was not statistically significant (p > 0.05). TE results for CFLD patients (5.9 kPa) also did not show a significant difference compared to non-CFLD patients (4.2 ± 1.6 kPa, p > 0.05). However, a positive correlation (r = 0.401, p = 0.031) was found between FIB-4 scores and TE-based LSM, suggesting a potential complementary diagnostic role. Conclusions: The FIB-4 index, while not sufficient as a standalone diagnostic tool for CFLD in adults with CF, demonstrates potential when used in conjunction with other diagnostic methods like TE. This study introduces a novel approach for integrating non-invasive diagnostic markers in CF care, offering a pathway for future clinical practice. The combination of FIB-4 and TE could serve as an accessible, cost-effective alternative to invasive diagnostic techniques, improving early diagnosis and management of CFLD in the CF population. Additionally, future research should explore the integration of these tools with emerging biomarkers and clinical features to refine diagnostic algorithms for CFLD, potentially reducing reliance on liver biopsies and improving patient outcomes.

Background and Objectives: Advanced liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD) can be a major predictor of cardiovascular disease (CVD) events and cardiac complications. However, the clinical significance of cardiac symptoms and abnormal electrocardiography (ECG) findings in patients with NAFLD associated with advanced liver fibrosis is unclear. Therefore, our study was aimed to evaluate the clinical implications based on the association between cardiac symptoms with ECG abnormalities for advanced liver fibrosis in patients with NAFLD. Materials and Methods: Of 31,795 participants who underwent health checkups, 6293 were diagnosed with NAFLD using ultrasound and inclusion criteria in a retrospective cross-sectional study. Advanced liver fibrosis was assessed based on a low NAFLD fibrosis score (NFS) and fibrosis-4 index (Fib-4) cut-off values (COVs). Cardiac data were assessed using a cardiac symptom questionnaire and 12-lead electrocardiography (ECG). Results: Among 6293 NAFLD patients with NAFLD, 304 (4.8%) experienced cardiac symptoms. NFS and Fib-4 indicated higher rates of advanced fibrosis in the cardiac-symptomatic group than in the non-symptomatic group (NFS: 7.3 vs. 4.1%; Fib-4: 7.8 vs. 3.7%; both p < 0.001). Cardiac symptoms were independently associated with advanced liver fibrosis using a step-wise-adjusted model and NFS and Fib-4 (final adjusted odds ratio (aOR), 1.40; 95% CI, 1.06–1.85; p = 0.018 for NFS; aOR, 1.67; 95%, 1.30–2.15; p < 0.001 for Fib-4). Cardiac symptoms with abnormal ECG findings independently predicted advanced liver fibrosis (aOR, 2.43; 95% CI, 1.72–3.39; p < 0.001 for NFS; aOR, 3.02; 95% CI, 2.19–4.15; p < 0.001 for Fib-4). Conclusions: Patients who have had cardiac symptoms and some ECG abnormalities may have a higher association with advanced liver fibrosis.

Background: Inflammatory bowel disease (IBD) is associated with an increased prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD). The Fibrosis-4 (FIB-4) index is a non-invasive tool for assessing liver fibrosis that has been validated in various liver diseases. The main objective of this study was to study whether the FIB-4 index is a reliable predictor of liver fibrosis, as assessed through elastography, in patients with IBD. We additionally aimed to analyze if FIB-4 associates with IBD characteristics such as lipid profile, subclinical carotid atherosclerosis, and insulin resistance indices. Methods: A cross-sectional study was conducted, enrolling 197 patients with IBD. Subjects underwent comprehensive clinical and laboratory evaluations. Hepatic fibrosis was assessed non-invasively using the FIB-4 index and transient elastography, while abdominal ultrasonography was performed to grade hepatic steatosis based on the degree of fat infiltration. To investigate the associations between disease characteristics and FIB-4 score and the correlation of this index to elastography, a multivariable linear regression analysis was conducted. Results: The presence of diabetes, hypertension, and metabolic syndrome was associated with significantly higher FIB-4 levels. However, FIB-4 did not show a relationship with disease characteristics such as phenotype or activity indices. Furthermore, FIB-4 did not demonstrate a correlation with liver stiffness values measured by elastography. Conclusions: Our findings suggest that the FIB-4 index may not be a reliable tool for assessing hepatic fibrosis in patients with IBD. This observation is particularly significant given the high prevalence of MASLD in the IBD population.

Background/Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is highly prevalent in patients with type 2 diabetes (T2D) and is associated with increased cardiovascular risk. However, the relative contribution of traditional cardiometabolic risk factors (CMRFs), hepatic fibrosis markers, and antidiabetic therapies to atherosclerosis remains unclear. Methods: We conducted a cross-sectional study including 46 patients with T2D and MASLD. Atherosclerotic cardiovascular disease (ASCVD) was defined as the presence of carotid atheromatosis, stroke, peripheral arterial disease, or ischemic heart disease, as assessed by imaging-based parameters. Clinical, metabolic, and treatment-related variables were analyzed, including age, Hemoglobin A1c (HbA1c), lipid profile, hepatic fibrosis indices such as Fibrosis-4 index (FIB-4), and antidiabetic therapies (sodium–glucose cotransporter-2 inhibitors (SGLT2is), glucagon-like peptide-1 receptor agonists (GLP-1 RAs), and insulin). Multivariable regression models and receiver operating characteristic (ROC) curve analyses were used to evaluate associations and discriminative performance. Results: Traditional CMRFs were more strongly associated with ASCVD than hepatic fibrosis markers or antidiabetic therapies. Age was associated with ASCVD in several exploratory models, although this association was attenuated in the fully adjusted model. HbA1c showed the highest discriminative performance (AUC 0.77), indicating that chronic glycemic exposure is a major determinant of vascular disease in this cohort. In contrast, FIB-4 was not associated with ASCVD and did not improve model performance. Antidiabetic therapies, including SGLT2i and GLP-1 RAs, were not independently associated with ASCVD. Insulin therapy was more frequent among patients with ASCVD, but was not independently associated after adjustment. Conclusions: In patients with T2D and MASLD, ASCVD appears to be associated with traditional CMRFs, particularly chronic glycemic exposure, rather than hepatic fibrosis markers or treatment status. These findings highlight the central role of metabolic control in cardiovascular risk and suggest that the contribution of liver-related markers and therapeutic interventions may be more relevant in longitudinal settings.

Purpose of ReviewHepatitis B virus (HBV) can be a potentially life-threatening liver infection. Prior to starting therapy, the first step is to establish the diagnosis, then to assess disease severity and determine if treatment is indicated. Assessing the degree of liver fibrosis is imperative to guiding treatment options. While liver biopsy has been the primary method to establish the degree of fibrosis, noninvasive tests (NIT) have now replaced liver biopsy as the initial step.Recent FindingsHere, we present a recent review of literature on NIT to assess liver fibrosis in chronic HBV from 2019 to 2022.SummaryBeing able to use NIT (blood- and/or imaging-based) to assess fibrosis and help guide treatment can help impact and lower disease burden as well as life-threatening complications of liver disease.

Hepatocellular carcinoma (HCC) is influenced not only by tumor burden but also by liver function and the extent of fibrosis. Although the albumin-bilirubin (ALBI) score and the fibrosis-4 (FIB-4) index are validated independent predictors, their combined prognostic impact has been insufficiently examined. We retrospectively analyzed 307 patients with HCC diagnosed between 2002 and 2025. ALBI and FIB-4 scores were calculated at baseline, and a composite score was generated using the β-coefficients obtained from a multivariable Cox regression model, allowing each component to contribute proportionally to its prognostic weight (combined score = 0.503 × ALBI + 0.0576 × FIB-4). Patients were stratified using the median cutoff value (-0.95). Outcomes included overall survival (OS), event-free survival (EFS) for those undergoing locoregional therapies, and progression-free survival (PFS) for patients treated with systemic therapy. Median OS was 12.1 months. Patients with combined scores ≤-0.95 had superior OS (18.3 vs 6.8 months, p < 0.001), and the score remained an independent predictor of OS (HR 2.01, 95% CI 1.48-2.72, p = 0.001). In the locoregional therapy group, lower scores predicted improved EFS (16.4 vs 5.8 months,: HR:1.86; 95% CI:1.17-2.96; p=0.009). Among systemic therapy patients, the combined score independently predicted PFS (HR 1.70, 95% CI 1.21-2.41, p = 0.021). The combined ALBI-FIB-4 score is an accessible and reproducible prognostic marker across therapeutic settings in HCC. By integrating measures of hepatic reserve and fibrosis, it provides additional prognostic granularity beyond tumor-centric staging systems. These findings highlight its potential utility in personalized risk stratification and warrant validation in prospective, multi-ethnic cohorts.
