RESUMEN
AIM: Recent genome-wide association studies of European populations have identified rs16906115, a single-nucleotide polymorphism in the interleukin-7 gene, as a predictor of immune-related adverse events (irAEs) and the therapeutic efficacy of immune checkpoint inhibitors. We evaluated this single-nucleotide polymorphism in a Japanese population. METHODS: From January 2021, we stored host DNA from individuals who received various types of immune checkpoint inhibitors. From this population, we categorized 510 participants into cases (grade ≥2 irAEs) and controls (received ≥3 immune checkpoint inhibitor doses, follow-up ≥12 weeks, no irAEs), and divided 339 hepatocellular carcinoma patients treated with atezolizumab/bevacizumab into responders and non-responders, evaluated using the modified response evaluation criteria in solid tumors. We compared the minor allele frequencies of rs16906115 between cases and controls, and responders and non-responders. RESULTS: In the irAE prediction analysis of 234 cases and 276 controls, the minor allele frequency was 0.244 in the case group and 0.265 in the control group. This difference is not significant. In the analysis predicting the therapeutic efficacy for hepatocellular carcinoma patients, the responders had a significantly lower minor allele frequency of 0.220, compared with 0.300 for the non-responders (p = 0.022). Univariate and multivariate analyses identified the minor allele homozygosity as a significant predictor of treatment response, with odds ratios of 0.292 (p = 0.015) in the univariate analysis and 0.315 (p = 0.023) in the multivariate analysis. CONCLUSIONS: In our Japanese cohort, no association was found between the rs16906115 minor allele and irAEs or treatment efficacy. The minor allele homozygosity may be associated with a negative therapeutic outcome. CLINICAL TRIAL REGISTRATION: UMIN Clinical Trials Registry with the number UMIN000043798.
RESUMEN
Background and Aims: As practice patterns and hepatitis C virus (HCV) genotypes (GT) vary geographically, a global real-world study from both East and West covering all GTs can help inform practice policy toward the 2030 HCV elimination goal. This study aimed to assess the effectiveness and tolerability of DAA treatment in routine clinical practice in a multinational cohort for patients infected with all HCV GTs, focusing on GT3 and GT6. Methods: We analyzed the sustained virological response (SVR12) of 15,849 chronic hepatitis C patients from 39 Real-World Evidence from the Asia Liver Consortium for HCV clinical sites in Asia Pacific, North America, and Europe between 07/01/2014-07/01/2021. Results: The mean age was 62±13 years, with 49.6% male. The demographic breakdown was 91.1% Asian (52.9% Japanese, 25.7% Chinese/Taiwanese, 5.4% Korean, 3.3% Malaysian, and 2.9% Vietnamese), 6.4% White, 1.3% Hispanic/Latino, and 1% Black/African-American. Additionally, 34.8% had cirrhosis, 8.6% had hepatocellular carcinoma (HCC), and 24.9% were treatment-experienced (20.7% with interferon, 4.3% with direct-acting antivirals). The largest group was GT1 (10,246 [64.6%]), followed by GT2 (3,686 [23.2%]), GT3 (1,151 [7.2%]), GT6 (457 [2.8%]), GT4 (47 [0.3%]), GT5 (1 [0.006%]), and untyped GTs (261 [1.6%]). The overall SVR12 was 96.9%, with rates over 95% for GT1/2/3/6 but 91.5% for GT4. SVR12 for GT3 was 95.1% overall, 98.2% for GT3a, and 94.0% for GT3b. SVR12 was 98.3% overall for GT6, lower for patients with cirrhosis and treatment-experienced (TE) (93.8%) but ≥97.5% for treatment-naive patients regardless of cirrhosis status. On multivariable analysis, advanced age, prior treatment failure, cirrhosis, active HCC, and GT3/4 were independent predictors of lower SVR12, while being Asian was a significant predictor of achieving SVR12. Conclusions: In this diverse multinational real-world cohort of patients with various GTs, the overall cure rate was 96.9%, despite large numbers of patients with cirrhosis, HCC, TE, and GT3/6. SVR12 for GT3/6 with cirrhosis and TE was lower but still excellent (>91%).
RESUMEN
Risk factors for hepatocarcinogenesis include chronic inflammation due to viral infection, liver fibrosis, and aging. In this study, we separated carcinogenic and non-carcinogenic cases due to hepatitis C virus (HCV) infection, aiming to comprehensively analyze miRNA expression in liver tissues by age, and identify factors that contribute to carcinogenesis. Total RNA was extracted from 360 chronic hepatitis C (CH), 43 HCV infected hepatocellular carcinoma (HCC), and surrounding non-tumor (SNT) tissues. MicroRNA (miRNA) expression patterns were analyzed using microarray. Using machine learning, we extracted characteristic miRNA expression patterns for each disease and age. There were no age-dependent changes in miRNA expression in the disease-specific comparisons; however, miRNA expression differed among the age groups of 50, 60, and 70 years of age between CH and SNT. The expression of miRNA was different between SNT and HCC only in patients in their 70s. Of the 55 miRNAs with significant differences in expression between CH and SNT, 34 miRNAs showed significant differences in expression even in the degree of liver fibrosis. The observation that miRNAs involved in hepatocarcinogenesis differ at different ages suggests that the mechanisms of carcinogenesis differ by age group as well. We also found that many miRNAs whose expression did not affect liver fibrosis were involved in carcinogenesis. These findings are expected to define biomarkers for detection of HCC at early stage, and develop novel therapeutic targets for HCC.

BACKGROUND: Steatotic liver disease (SLD) is associated with adverse cardiac events. Metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as a condition characterized by the abnormal accumulation of hepatic lipids that is closely linked to five metabolic disorders: overweight or obesity, impaired glucose regulation, hypertension, hypertriglyceridemia, and low high-density lipoprotein-cholesterol. This retrospective study aimed to stratify the risk of cardiac events in patients with MASLD. METHODS: Patients diagnosed with MASLD through ultrasonography were evaluated. We implemented a machine learning-based approach using a survival classification and regression tree (CART) model to stratify patients based on age, and the number of risk scores was investigated as a predictor of adverse outcomes in the derivation cohort. The primary outcomes were major adverse cardiac events (MACE) including cardiac death, nonfatal myocardial infarction, and revascularization due to coronary artery disease. RESULTS: Among 2,962 patients (median age, 62 years; men, 53.5 %), the distribution of risk factors was as follows: one (10.8 %), two (28.5 %), three (33.0 %), four (19.9 %), and five (7.8 %). Over a median follow-up period of 6.8 years, 170 (5.7 %) patients experienced MACE. In the derivation cohort of 2,073 patients, the CART model identified age ≥60 years old and risk factors ≥4 as significant predictors of MACE. These findings were corroborated in a validation cohort of 889 patients. Patients meeting both criteria exhibited the highest risk of MACE (log-rank test, p < 0.001). CONCLUSIONS: Patients aged ≥60 years old with risk factors ≥4 indicates at high risk of MACE in patients with MASLD. This risk stratification system provides a practical tool for identifying high-risk individuals in the MASLD population.
RESUMEN
BACKGROUND: The aims of this study were to identify clinically significant biomarkers of a response to atezolizumab plus bevacizumab (ATZ + BV) therapy and to develop target strategies against unresectable hepatocellular carcinoma (u-HCC). METHOD: We first investigated the potential of circulating tumor DNA (ctDNA) to serve as a biomarker for predicting the therapeutic outcome in 24 u-HCC patients treated with ATZ + BV therapy. Next, we analyzed levels of immune-related cytokines in blood samples from 134 u-HCC patients who received ATZ + BV. For this, serum immune-related molecules or cancer-immune cycle-related molecules that have been reported in HCC patient sera, namely CD274, LAG-3, CCL2, 4, 5, CXCL1, 9, 10, 12, 13, CX3CL1, CCR5, IFNγ and IL-6, 8 were measured using enzyme-linked immunosorbent assay. RESULTS: More than 1% of variant read frequency (VRF) mutations were found in TP53, APC, PIK3CA and VHL, although with no correlation with treatment response. Among the 15 cytokines evaluated, CXCL9 and LAG-3 levels were significantly different between patients with objective response (OR), stable disease (SD), and progressive disease (PD) following ATZ + BV treatment. Receiver-operating characteristic curve analyses of CXCL9 (cut-off value: 419.1 pg/ml) and LAG-3 (cut-off value: 3736.3 pg/ml) indicated areas of 0.779 and 0.697, respectively, for differentiating PD from non-PD and OR from non-OR. In multivariate analysis of progression-free survival (PFS) and overall survival (OS), high serum CXCL9 (hazard ratio (HR) and 95% confidence interval (CI): 0.412 (0.251-0.677) (p = 0.0005) for PFS and 0.252 (0.125-0.508) (p = 0.0001) for OS), and low serum LAG-3 (HR and 95% CI 0.419 (0.249-0.705) (p = 0.0011) for PFS and 0.294 (0.140-0.617) (p = 0.0012) for OS) were independent positive predictive factors. CONCLUSION: Although, as far as we examined, no ctDNA mutations in blood were found to be related to ATZ + BV treatment efficacy, serum CXCL9 and LAG-3 levels, which are related to the cancer-immune cycle, were associated with treatment efficacy and could be predictive markers of the efficacy of ATZ + BV treatment in HCC patients.
RESUMEN
BACKGROUND: There is a need for novel noninvasive markers for metabolic dysfunction-associated steatotic liver disease (MASLD) to stratify patients at high risk for liver-related events including liver cancer and decompensation. In the present study, we used proteomic analysis of proteins in extracellular vesicles (EVs) to identify new biomarkers that change with fibrosis progression and can predict the development of liver-related events. METHODS: We analyzed serum EVs from 50 patients with MASLD assessed for liver fibrosis by biopsy and identified proteins that altered with advanced fibrosis. A further evaluation was conducted on another cohort of 463 patients with MASLD with biopsy. RESULTS: Eight candidate proteins were identified by proteomic analysis of serum EVs. Among them, serum levels of Fibulin-3, Fibulin-1, and Ficolin 1 correlated with their EV levels. In addition, serum Fibulin-3 and serum Fibulin-1 levels changed significantly with advanced fibrosis. Using another cohort with biopsy, we found that the serum Fibulin-3 concentration was significantly greater in those with advanced fibrosis but that the serum Fibulin-1 concentration was not significantly different. Multivariate Cox proportional hazards analysis revealed that a higher Fibrosis-4 (FIB-4) index and higher serum Fibulin-3 concentration were independent risk factors for liver-related events. When the cutoff value for the serum Fibulin-3 concentration was 6.0 µg/mL according to the Youden index of AUROCs, patients with high serum Fibulin-3 significantly more frequently developed liver-related events than did other patients. Validation using another cohort of 226 patients with clinically diagnosed MASLD confirmed that high serum Fibulin-3 levels are associated with a greater frequency of liver-related events. CONCLUSIONS: Serum Fibulin-3 was identified as a biomarker for predicting liver-related events in patients with MASLD.

BACKGROUND AND AIMS: Although metabolic dysfunction-associated steatotic liver disease (MASLD) patients with a Fib-4 index >1.3 are recommended for fibrosis evaluation via elastography or biopsy, a more convenient method identifying high-risk populations requiring follow-up is needed. We explored the utility of serum levels of growth differentiation factor-15 (GDF15), a cell stress-responsive cytokine related to metabolic syndrome, for stratifying the risk of clinical events in MASLD patients. METHODS: Serum GDF15 levels were measured in 518 biopsy-performed MASLD patients, 216 MASLD patients for validation, and 361 health checkup recipients with MASLD. RESULTS: In the biopsy-MASLD cohort, multivariate analysis indicated that the serum GDF15 level was a risk factor for liver cancer, independent of the fibrosis stage or Fib-4 index. Using a GDF15 cutoff of 1.75 ng/mL based on the Youden index, high-GDF15 patients, regardless of fibrosis status, had a higher liver cancer incidence rate. While patients with a Fib-4 index <1.3 or low-GDF15 rarely developed liver cancer, high-GDF15 patients with a Fib-4 index >1.3 developed liver cancer and decompensated liver events at significantly higher rates and had poorer prognoses. In the validation cohort, high-GDF15 patients had significantly higher incidences of liver cancer and decompensated liver events and poorer prognoses than low-GDF15 patients, whether limited to high-Fib-4 patients. Among health checkup recipients with MASLD, 23.0% had a Fib-4 index >1.3, 2.7% had a Fib-4 index >1.3 and >1.75 ng/mL GDF15. CONCLUSIONS: Serum GDF15 is a biomarker for liver cancer with high predictive capability and is useful for identifying MASLD patients requiring regular surveillance.

Atezolizumab plus bevacizumab (Atez/BV) as first-line therapy and lenvatinib (LEN) as second-line therapy are the recommended treatments for patients with unresectable hepatocellular carcinoma. Adverse immune events caused by immune checkpoint inhibitors (such as Atez) generally only occur several months after administration; therefore, the potential influence of the first-line treatment on second-line treatment is not clear. The present study investigated the safety of second-line LEN treatment (2nd LEN) by comparing the adverse events (AEs) of 2nd LEN after first-line Atez/BV treatment for unresectable liver cancer, with those of first-line LEN treatment (1st LEN). Patients who received Atez/BV as first-line therapy and 2nd LEN, or those who received 1st LEN at Ogaki Municipal Hospital (Ogaki, Japan) between April 2018 and September 2023 were retrospectively evaluated for treatment duration and AEs. The median treatment duration for patients in the 1st LEN (n=39) and 2nd LEN (n=13) groups was 151.0 days [95% confidence interval (CI) 77-303 days] and 128.5 days (95% CI 68-270 days), respectively (P=0.385). A greater proportion of patients showed elevated aspartate aminotransferase/alanine aminotransferase levels in the 2nd LEN group (76.9%) compared with those in the 1st LEN group (46.2%) (P=0.016). Hypothyroidism was more common in those receiving 2nd LEN (46.2%) than 1st LEN (12.8%) (P=0.016). In addition, grade 1 (three patients) and grade 2 (three patients) hypothyroidism was observed in patients receiving 2nd LEN. For these six patients, during first-line Atez/BV treatment, four patients had grade 0 hypothyroidism and two patients had grade 1 hypothyroidism (P=0.025). In conclusion, patients receiving 2nd LEN after treatment with Atez/BV are at an increased risk of hypothyroidism.
RESUMEN
Introduction: Lenvatinib is indicated for the forefront treatment of advanced hepatocellular carcinoma (aHCC), but its use may be limited by the risk of esophagogastric varices (EGV) bleeding. This study assessed the prevalence, predictors, and complications of EGV in aHCC patients treated with lenvatinib. Methods: In this multicenter international retrospective study, cirrhotic patients treated with lenvatinib for aHCC, were enrolled if upper-gastrointestinal endoscopy was available within 6 months before treatment. Primary endpoint was the incidence of EGV bleeding during lenvatinib therapy; secondary endpoints were predictors for EGV bleeding, prevalence, and risk factors for the presence of EGV and high-risk EGV at baseline, as well as impact of EGV bleeding on patients' survival. Results: 535 patients were enrolled in the study (median age: 72 years, 78% male, 63% viral etiology, 89% Child-Pugh A, 16% neoplastic portal vein thrombosis [nPVT], 56% Barcelona Clinic Liver Cancer-C): 234 had EGV (44%), 70 (30%) were at high risk and 59 were on primary prophylaxis. During lenvatinib treatment, 17 patients bled from EGV (3 grade 5), the 12-month cumulative incidence being 3%. The only baseline independent predictor of EGV bleeding was the presence of baseline high-risk EGV (hazard ratio: 6.94, 95% confidence interval [CI]: 2.23-21.57, p = 0.001). In these patients the 12-month risk was 17%. High-risk varices were independently associated with Child-Pugh B score (odds ratio [OR]: 2.12; 95% CI: 1.08-4.17, p = 0.03), nPVT (OR: 2.54; 95% CI: 1.40-4.61, p = 0.002), and platelets <150,000/µL (OR: 2.47; 95% CI: 1.35-4.50, p = 0.003). Conclusion: In hepatocellular carcinoma patients treated with lenvatinib, the risk of EGV bleeding was mostly low but significant only in patients with high-risk EGV at baseline.
RESUMEN
AIM: No pharmacotherapeutic treatment has been established for metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH). This trial compared the effects of pemafibrate and omega-3-acid ethyl ester on hepatic function in patients with hypertriglyceridemia complicated by MASLD. METHODS: Patients with hypertriglyceridemia complicated by MASLD were enrolled, randomly assigned to the pemafibrate or omega-3-acid ethyl ester group, and followed for 24 weeks. The primary endpoint was the change in alanine aminotransferase (ALT) from baseline to week 24. The secondary endpoints included other hepatic enzymes, lipid profiles, and hepatic fibrosis biomarkers. RESULTS: A total of 80 patients were enrolled and randomized. The adjusted mean change in ALT from baseline to week 24 was significantly lower in the pemafibrate group (-19.7±5.9 U/L) than in the omega-3-acid ethyl ester group (6.8±5.5 U/L) (intergroup difference, -26.5 U/L; 95% confidence interval, -42.3 to -10.7 U/L; p=0.001). Pemafibrate significantly improved the levels of other hepatic enzymes (aspartate aminotransferase and gamma-glutamyl transpeptidase), lipid profiles (triglycerides, total cholesterol, high-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol), and hepatic fibrosis biomarkers (Mac-2 binding protein glycan isomer and Fibrosis-4 index). No cases of discontinuation due to adverse drug reactions were identified in either group, and there were no safety concerns. CONCLUSIONS: Pemafibrate is recommended over omega-3-acid ethyl ester for lipid management and MASLD treatment in patients with hypertriglyceridemia complicated by MASLD. The study results may contribute to the development of future treatment strategies for patients with MASLD/MASH.
RESUMEN
Introduction Abdominal angiography procedures such as transarterial chemoembolization (TACE) are essential for hepatocellular carcinoma treatment. One method commonly used is transfemoral access (TFA). However, issues associated with this method, which include postoperative compression of the puncture site and long periods of bed rest, can affect patient satisfaction. Thus, transradial access (TRA), a minimally invasive treatment method that improves treatment quality, was developed for TACE. This retrospective, multicenter study aimed to investigate the efficacy and safety of abdominal angiography using the radial artery approach. Methods In total, 1,601 patients underwent abdominal angiography using TRA and received treatment (radial access for visceral intervention (RAVI)) at 14 institutions in Japan. The treatment time, procedure completion rate, patient satisfaction, and complications were investigated. Results The success rate of RAVI was 99.4%, and the complication rate was 1.2%. Approximately 98.2% of the patients requested the radial artery approach again. There were no significant differences in the success rate of RAVI and the incidence of complications based on the operator's years of experience or the patient's age. Some patients developed minor complications such as puncture site bleeding, hematoma, vascular pain, and vasospasm. Further, serious complications (cerebral infarction (n = 1), cerebellar infarction (n = 1), and aortic dissection (n = 1)) were observed. Conclusion Similar to the conventional TFA, RAVI helped in facilitating peritoneal angiography safely. In abdominal angiography, this method can reduce patient burden and can be widely used in the future from the perspective of clinical benefit.
RESUMEN
BACKGROUND: Atezolizumab plus bevacizumab (Atezo/Bev) is frequently selected as the primary systemic therapy for hepatocellular carcinoma (HCC). AIMS: To investigate the outcomes of patients with HCC treated with Atezo/Bev in a real-world setting based on whether they met the inclusion criteria for the phase 3 IMbrave150 trial. METHODS: A total of 936 patients were enrolled. There were 404 patients who met the inclusion criteria of the phase 3 IMbrave150 trial (IMbrave150 group) and 532 who did not (non-IMbrave150 group). RESULTS: Median progression-free survival (PFS) in the IMbrave150 and non-IMbrave150 groups was 7.4 months and 5.6 months (p = 0.002). Multivariable analysis revealed that non-B, non-C HCC aetiology (hazard ratio [HR], 1.173), α-fetoprotein ≥100 ng/mL (HR, 1.472), Barcelona Clinic Liver Cancer stage ≥ C (HR, 1.318), and modified albumin-bilirubin (mALBI) grade 2b or 3 (HR, 1.476) are independently associated with PFS. Median overall survival (OS) in the IMbrave150 and non-Imbrave150 groups was 26.5 and 18.8 months (p < 0.001). Multivariable analysis revealed that Eastern Cooperative Oncology Group performance status ≥2 (HR, 1.986), α-fetoprotein ≥100 ng/mL (HR, 1.481), and mALBI grade 2b or 3 (HR, 2.037) are independently associated with OS. In subgroup analysis, there were no significant differences in PFS or OS between these groups among patients with mALBI grade 1 or 2a. CONCLUSIONS: Patients who are treated with Atezo/Bev and meet the inclusion criteria for the phase 3 IMbrave150 trial, as well as those who do not meet the inclusion criteria but have good liver function, have a good prognosis for survival.

BACKGROUND: This study aimed to clarify the morphological changes in esophageal varices after achieving sustained virological response (SVR) with direct-acting antivirals (DAAs) in patients with cirrhosis. METHODS: A total of 243 patients underwent esophagogastroduodenoscopy before DAA treatment and after achieving SVR. Morphological changes in esophageal varices were investigated using esophagogastroduodenoscopy. RESULTS: This study comprised 125 males and 118 females with a median age of 68 years. Esophageal varices at baseline were classified into no varix in 155 (63.8%), F1 in 59 (24.3%), F2 in 25 (10.3%) and F3 in 4 (1.6%) patients. The improvement, unchanged, and aggravation rates of esophageal varices after SVR were 11.9%, 73.3%, and 14.8%, respectively. High ALBI score at SVR12 was an independent factor associated with post-SVR esophageal varices aggravation (p = 0.045). Time-dependent receiver operating characteristic (ROC) curve analysis revealed a cut-off value of - 2.33 for ALBI score at SVR12 in predicting post-SVR esophageal varices aggravation. Of the 155 patients without esophageal varices at baseline, 17 developed de novo post-SVR esophageal varices. High ALBI score at SVR12 was a significant independent factor associated with de novo post-SVR esophageal varices (p = 0.046). ROC curve analysis revealed a cut-off value of - 2.65 for ALBI score at SVR12 in predicting de novo post-SVR esophageal varices. CONCLUSIONS: Patients with cirrhosis can experience esophageal varices aggravation or de novo esophageal varices, despite achieving SVR. In particular, patients with high ALBI score at SVR12 have a high likelihood of developing post-SVR esophageal varices aggravation or de novo post-SVR esophageal varices.

AIMS: The aim of the present study was to elucidate detailed parameters for prediction of prognosis for patients with unresectable hepatocellular carcinoma (uHCC) receiving atezolizumab plus bevacizumab (Atez/Bev) treatment. METHODS: A total of 719 patients (males 577, median age 74 years) treated with Atez/Bev between September 2020 and January 2023 were enrolled. Factors related to overall survival (OS) were extracted and a prognostic scoring system based on hazard ratio (HR) was created. OS and progression-free survival (PFS) were retrospectively examined, and the prognostic ability of the newly developed system was compared to CRAFITY score using concordance index (c-index) and Akaike information criterion (AIC) results. RESULTS: Cox-hazards multivariate analysis showed BCLC classification C/D (HR 1.4; 1 point), AFP ≥100 ng/mL (HR 1.4; 1 point), mALBI 2a (HR 1.7; 1 point), mALBI 2b/3 (HR 2.8; 2 points), and DCP ≥100 mAU/mL (HR 1.6; 1 point) as significant factors. The assigned points were added and used to develop the IMmunotherapy with AFP, BCLC staging, mALBI, and DCP evaluation (IMABALI-De) scoring system. For IMABALI-De scores of 0, 1, 2, 3, 4, and 5, OS was not applicable (NA), NA, 26.11, 18.79, 14.07, and 8.32 months, respectively (p < .001; AIC 2788.67, c-index 0.699), while for CRAFITY scores of 0, 1, and 2, OS was 26.11, 20.29, and 11.32 months, respectively (p < .001; AIC 2864.54, c-index 0.606). PFS periods for those IMABALI-De scores were 21.75, 12.89, 9.18, 8.0, 5.0, and 3.75 months, respectively (p < .001; AIC 5203.32, c-index 0.623) and for the CRAFITY scores were 10.32, 7.68, and 3.57 months, respectively (p < .001; AIC 5246.61, c-index 0.574). As compared with CRAFITY score, IMABALI-De score had better AIC and c-index results for both OS and PFS. CONCLUSION: The present results indicated that the proposed IMABALI-De score may be favorable for predicting prognosis of uHCC patients receiving Atez/Bev therapy.

BACKGROUND AND AIMS: Because the accuracy of the Fibrosis-4 (FIB-4) index for predicting liver fibrosis changes with age, the need for different cut-offs in various age groups has frequently been discussed. We developed the age-independent score, the Fibrosis-3 (FIB-3) index, and have shown its usefulness in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). This study aimed to validate the diagnostic ability of the FIB-3 index to predict fibrosis progression using a large new patient cohort. METHODS: The ability of the FIB-3 index to predict liver fibrosis was analyzed by comparing it with that of the FIB-4 index using data from 1398 patients with MASLD enrolled in the Asia-based clinical outcome NAFLD study. RESULTS: The areas under the receiver operating characteristic curves for predicting fibrosis stage F3 or higher were not different between the FIB-3 and FIB-4 indices in the entire cohort. Using the single ideal cut-offs of the indices (3.41 for FIB-3 index and 2.01 for FIB-4 index), the predictive accuracy of the FIB-3 index was not significantly different from that of the FIB-4 index among patients aged <60 years; however, the accuracy of the FIB-3 index was significantly higher than that of the FIB-4 index in those aged ≥60 years (0.645 and 0.529, respectively; p < 0.0001). CONCLUSION: The high ability of the FIB-3 index with a single cut-off to predict liver fibrosis in patients with MASLD was confirmed. The FIB-3 index could serve as a useful tool for assessing liver fibrosis regardless of age.
RESUMEN
Introduction: Natural killer (NK) cells play a pivotal role in immune surveillance in the liver. We aimed to identify potential targets for NK cell-mediated immune intervention by revealing the functional molecules on NK cells in HCC patients. Methods: To evaluate the impact of aging on NK cell phenotypes, we examined NK cells from healthy volunteers (HVs) of various ages. Because ILT2 expression on CD56dim NK cells increased with increasing age, we enrolled age-matched HCC patients and HVs. We determined the NK cell phenotypes in blood mononuclear cells (PBMCs) and intrahepatic lymphocytes (IHLs) from cancerous and non-cancerous tissues. We evaluated cytotoxicity and antibody-dependent cellular cytotoxicity (ADCC) of NK cells in vitro. Results: ILT2-positive CD56dim NK cells in PBMCs were increased in HCC patients compared with HVs. In HCC patients, ILT2-positive CD56dim NK cells were increased in cancerous IHLs compared with non-cancerous IHLs and PBMCs. We examined the impact of macrophage migration inhibitory factor (MIF) on ILT2 expression in co-cultures of HCC cells and NK cells. The enhanced expression of ILT2 on CD56dim NK cells from HCC patients was inhibited by masking antibodies against MIF and CXCR4. ILT2-positive CD56dim NK cells exhibited lower capacities for cytotoxicity and ADCC than ILT2-negative cells, which were partially restored by ILT2 blockade. Conclusions: In HCC patients, ILT2 is a signature molecule for cancerous CD56dim NK cells with impaired cytolytic capacity. The MIF-CXCR4 interaction is associated with ILT2 induction on CD56dim NK cells and ILT2 serves as a target for functional NK cell restoration.

AIM: An association between hepatitis B core-related antigen (HBcrAg) kinetics and hepatocarcinogenesis during nucleoside (t)id analog (NA) treatment has recently been reported. HBcrAg kinetics and factors associated with HBcrAg response during tenofovir alafenamide (TAF) administration remain unclear. In this multicenter retrospective study, we aimed to clarify the efficacy and safety of TAF in treatment-naïve patients with chronic hepatitis B, focusing on the reduction in HBcrAg levels. METHODS: Patients were treated with TAF monotherapy for 96 weeks, and the kinetics of HBcrAg during treatment and the factors associated with HBcrAg response (defined as a change in HBcrAg of -1 log IU/mL from baseline) were evaluated. RESULTS: The study population comprised 241 patients, 36.9% of whom were HBeAg-positive. The median baseline HBcrAg level was 4.7 log IU/mL. The median change in HBcrAg from baseline was -1.1 log IU/mL at 96 weeks after treatment. The HBcrAg response rate at 96 weeks was 56.6% (43/76). Multivariate analysis revealed high alanine transaminase level as an independent baseline factor associated with HBcrAg response at 96 weeks of treatment (p = 4.53 × 10-6). No correlation was found between the HBcrAg and hepatitis B surface antigen kinetics in patients treated with TAF monotherapy. CONCLUSIONS: In TAF monotherapy for patients with chronic hepatitis B, HBcrAg levels were significantly decreased and baseline alanine transaminase level is an important factor associated with HBcrAg reduction. As no correlation was found between HBcrAg and reduced hepatitis B surface antigen levels in this study, HBcrAg kinetics in addition to hepatitis B surface antigen may need to be monitored during TAF treatment.
RESUMEN
BACKGROUND: In the context of patients with hepatocellular carcinoma (HCC) treated with systemic therapy, the correlation between the appearance of adverse events (AEs) and reported efficacy outcomes is well-known and widely investigated. From other pathological settings, we are aware of the prognostic and predictive value of the occurrence of immune-related AEs in patients treated with immune-checkpoint inhibitors. OBJECTIVE: This retrospective multicenter real-world study aims to investigate the potential prognostic value of AEs in patients with HCC treated with atezolizumab plus bevacizumab in the first-line setting. PATIENTS AND METHODS: The study population consisted of 823 patients from five countries (Italy, Germany, Portugal, Japan, and the Republic of Korea). RESULTS: Of the patients, 73.3% presented at least one AE during the study period. The most common AEs were proteinuria (29.6%), arterial hypertension (27.2%), and fatigue (26.0%). In all, 17.3% of the AEs were grade (G) 3. One death due to bleeding was reported. The multivariate analysis confirmed the appearance of decreased appetite G < 2 [versus G ≥ 2; hazard ratio (HR) 0.60; 95% confidence interval (CI) 0.13-0.90; p < 0.01] and immunotoxicity G < 2 (versus G ≥ 2; HR: 0.70; 95% CI 0.24-0.99; p = 0.04) as independent prognostic factors for overall survival, and the appearance of decreased appetite G < 2 (versus G ≥ 2; HR: 0.73; 95% CI 0.43-0.95; p = 0.01), diarrhea (yes versus no; HR: 0.57, 95% CI 0.38-0.85; p = 0.01), fatigue (yes versus no; HR: 0.82, 95% CI 0.65-0.95; p < 0.01), arterial hypertension G < 2 (versus G ≥ 2; HR: 0.68, 95% CI 0.52-0.87; p < 0.01), and proteinuria (yes versus no; HR: 0.79, 95% CI 0.64-0.98; p = 0.03) as independent prognostic factors for progression-free survival. CONCLUSIONS: As demonstrated for other therapies, there is also a correlation between the occurrence of AEs and outcomes for patients with HCC for the combination of atezolizumab plus bevacizumab.

BACKGROUND AND AIM: Direct-acting antivirals (DAAs) have been accessible in Japan since 2014. The aim of this study is to compare how the prognosis of patients with hepatitis C virus (HCV)-associated hepatocellular carcinoma (HCV-HCC) changed before and after DAA development. METHODS: A retrospective analysis of 1949 Japanese HCV-HCC patients from January 2000 to January 2023 categorized them into pre-DAA (before 2013, n = 1169) and post-DAA (after 2014, n = 780) groups. Changes in clinical features and prognosis were assessed. RESULTS: Despite no significant differences in BCLC stage between groups, the post-DAA group exhibited higher rates of sustained virological response (SVR) (45.6% vs. 9.8%), older age (73 vs 69 years), lower levels of AST (40 vs 56 IU/L), ALT (31 vs 46 IU/L), and AFP (11.7 vs 23.6 ng/mL), higher platelet count (13.5 vs 10.8 × 104/µL), better prothrombin time (88.0% vs 81.9%), and better ALBI score (-2.54 vs -2.36) (all P < 0.001). The post-DAA group also showed higher rates of curative treatments (74.1% vs 65.2%) and significantly improved recurrence-free survival (median 2.8 vs 2.1 years). Adjusted for inverse probability weighting, overall survival was superior in the post-DAA group (median 7.4 vs 5.6 years, P < 0.001). Subanalysis within the post-DAA group revealed significantly shorter overall survival for patients without SVR (median 4.8 years vs NA vs NA) compared to pre-SVR or post-SVR patients (both P < 0.001). No significant difference in OS was observed between the pre-SVR and post-SVR groups (P = 1.0). CONCLUSION: The development of DAA therapy has dramatically improved the prognosis of HCV-HCC patients.

AIMS: A multi-stakeholder consensus has proposed MASLD (metabolic dysfunction-associated steatotic liver disease). We aimed to investigate the pathological findings related to the mid-term mortality of patients with biopsy-proven MASLD in Japan. METHODS: We enrolled 1349 patients with biopsy-proven MASLD. The observational period was 8010 person years. We evaluated independent factors associated with mortality in patients with MASLD by Cox regression analysis. We also investigated pathological profiles related to mortality in patients with MASLD using data-mining analysis. RESULTS: The prevalence of MASH and stage 3/4 fibrosis was observed in 65.6% and 17.4%, respectively. Forty-five patients with MASLD died. Of these, liver-related events were the most common cause at 40% (n = 18), followed by extrahepatic malignancies at 26.7% (n = 12). Grade 2/3 lobular inflammation and stage 3/4 fibrosis had a 1.9-fold and 1.8-fold risk of mortality, respectively. In the decision-tree analysis, the profiles with the worst prognosis were characterised by Grade 2/3 hepatic inflammation, along with advanced ballooning (grade 1/2) and fibrosis (stage 3/4). This profile showed a mortality at 8.3%. Furthermore, the random forest analysis identified that hepatic fibrosis and inflammation were the first and second responsible factors for the mid-term prognosis of patients with MASLD. CONCLUSIONS: In patients with biopsy-proven MASLD, the prevalence of MASH and advanced fibrosis was approximately 65% and 20%, respectively. The leading cause of mortality was liver-related events. Hepatic inflammation and fibrosis were significant factors influencing mid-term mortality. These findings highlight the importance of targeting inflammation and fibrosis in the management of patients with MASLD.
