RESUMO
BACKGROUND: Statins have multiple benefits in patients with metabolic-associated steatotic liver disease (MASLD). AIM: To explore the effects of statins on the long-term risk of all-cause mortality, liver-related clinical events (LREs) and liver stiffness progression in patients with MASLD. METHODS: This cohort study collected data on patients with MASLD undergoing at least two vibration-controlled transient elastography examinations at 16 tertiary referral centres. Cox regression analysis was performed to examine the association between statin usage and long-term risk of all-cause mortality and LREs stratified by compensated advanced chronic liver disease (cACLD): baseline liver stiffness measurement (LSM) of ≥10 kPa. Liver stiffness progression was defined as an LSM increase of ≥20% for cACLD and from <10 kPa to ≥10 or LSM for non-cACLD. Liver stiffness regression was defined as LSM reduction from ≥10 kPa to <10 or LSM decrease of ≥20% for cACLD. RESULTS: We followed up 7988 patients with baseline LSM 5.9 kPa (IQR 4.6-8.2) for a median of 4.6 years. At baseline, 40.5% of patients used statins, and cACLD was present in 17%. Statin usage was significantly associated with a lower risk of all-cause mortality (adjusted HR=0.233; 95% CI 0.127 to 0.426) and LREs (adjusted HR=0.380; 95% CI 0.268 to 0.539). Statin usage was also associated with lower liver stiffness progression rates in cACLD (HR=0.542; 95% CI 0.389 to 0.755) and non-cACLD (adjusted HR=0.450; 95% CI 0.342 to 0.592), but not with liver stiffness regression (adjusted HR=0.914; 95% CI 0.778 to 1.074). CONCLUSIONS: Statin usage was associated with a relatively lower long-term risk of all-cause mortality, LREs and liver stiffness progression in patients with MASLD.
RESUMO
AIM: Antiviral treatment reduces the risk of developing hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. However, there is a lack of high-quality evidence regarding the preventive effects of tenofovir alafenamide (TAF) on HCC. We evaluated the impact of TAF use after curative treatment on HCC recurrence. METHODS: Patients who underwent surgery or radiofrequency ablation as a curative treatment for HCC were selected. Those patients who continued antiviral treatment with nucleos(t)ide analogs (NAs; entecavir [ETV] or tenofovir disoproxil fumarate [TDF]) or switched to TAF were included. The primary outcome was HCC recurrence, and the time-varying effect of NA use on HCC recurrence was analyzed using various statistical methods. RESULTS: Among 2794 consecutive patients with chronic hepatitis B who received curative treatment for HCC, 199 subsequently switched from ETV or TDF to TAF. After a median of 3.0 years, 1303 patients (46.6%) experienced HCC recurrence. After propensity score matching (ratio 1:10), switching to TAF was not associated with an increased HCC recurrence (HR 1.00, 95% CI 0.68-1.47; p = 1.00) by time-varying Cox analysis. Switching to TAF was not associated with HCC recurrence in subgroups of NA (HR 1.06, 95% CI 0.67-1.67; p = 0.81 for TDF, and HR 1.09, 95% CI 0.51-2.33; p = 0.82 for ETV). Kaplan-Meier analysis showed comparable HCC recurrence-free survival between patients who switched to TAF and those who continued with their NA (p = 0.08). Time-varying Cox analyses in various subgroups confirmed the primary findings. CONCLUSIONS: TAF is as effective as TDF and ETV in preventing HCC recurrence after curative treatment.
RESUMO
BACKGROUND AND AIM: Lack of awareness disturbs proper care for hepatitis C virus (HCV) infections in patients undergoing surgery. We investigated the status of HCV screening, confirmation, and treatment in patients who underwent surgery. METHODS: Patients who underwent surgery at a tertiary academic center between 2019 and 2021 were eligible for this retrospective study. RESULTS: Between 2019 and 2021, 96 894 patients (40 121 males; 41.4%) who underwent surgery under general anesthesia were recruited. The median age of the participants was 55.0 years. Of the 83 920 (86.6%) patients who tested positive for anti-HCV antibodies, 576 (0.7%) showed positive results, with a higher proportion of patients with diabetes mellitus (32.6% vs 18.5%), hypertension (50.5% vs 28.6%), liver cirrhosis (13.2% vs 1.7%), and unfavorable laboratory test results when compared with those with negative results (all P < 0.05). HCV RNA was tested in 215 patients (37.3%), with a positivity rate of 20.5% (n = 44). Of the 44 patients, 42 (95.5%) were referred for antiviral treatment, and 29 (69.0%) were successfully treated with direct-acting antiviral therapy. HCV RNA confirmation rates were higher in the Department of Hepatobiliary and Transplant Surgery (76.6%) than in the other surgical departments (25.0-33.5%) (P < 0.001). CONCLUSIONS: The proportion of patients who were positive for anti-HCV antibodies and failed to receive proper management after surgery was not negligible. Increased awareness of HCV infection among surgeons through appropriate education may be required.

Importance: Metabolic dysfunction-associated steatotic liver disease (MASLD) is currently the most common chronic liver disease worldwide. It is important to develop noninvasive tests to assess the disease severity and prognosis. Objective: To study the prognostic implications of baseline levels and dynamic changes of the vibration-controlled transient elastography (VCTE)-based scores developed for the diagnosis of advanced fibrosis (Agile 3+) and cirrhosis (Agile 4) in patients with MASLD. Design, Setting, and Participants: This cohort study included data from a natural history cohort of patients with MASLD who underwent VCTE examination at 16 tertiary referral centers in the US, Europe, and Asia from February 2004 to January 2023, of which the data were collected prospectively at 14 centers. Eligible patients were adults aged at least 18 years with hepatic steatosis diagnosed by histologic methods (steatosis in ≥5% of hepatocytes) or imaging studies (ultrasonography, computed tomography or magnetic resonance imaging, or controlled attenuation parameter ≥248 dB/m by VCTE). Main Outcomes and Measures: The primary outcome was liver-related events (LREs), defined as hepatocellular carcinoma or hepatic decompensation (ascites, variceal hemorrhage, hepatic encephalopathy, or hepatorenal syndrome), liver transplant, and liver-related deaths. The Agile scores were compared with histologic and 8 other noninvasive tests. Results: A total of 16â¯603 patients underwent VCTE examination at baseline (mean [SD] age, 52.5 [13.7] years; 9600 [57.8%] were male). At a median follow-up of 51.7 (IQR, 25.2-85.2) months, 316 patients (1.9%) developed LREs. Both Agile 3+ and Agile 4 scores classified fewer patients between the low and high cutoffs than most fibrosis scores and achieved the highest discriminatory power in predicting LREs (integrated area under the time-dependent receiver-operating characteristic curve, 0.89). A total of 10â¯920 patients (65.8%) had repeated VCTE examination at a median interval of 15 (IQR, 11.3-27.7) months and were included in the serial analysis. A total of 81.9% of patients (7208 of 8810) had stable Agile 3+ scores and 92.6% of patients (8163 of 8810) had stable Agile 4 scores (same risk categories at both assessments). The incidence of LREs was 0.6 per 1000 person-years in patients with persistently low Agile 3+ scores and 30.1 per 1000 person-years in patients with persistently high Agile 3+ scores. In patients with high Agile 3+ score at baseline, a decrease in the score by more than 20% was associated with substantial reduction in the risk of LREs. A similar trend was observed for the Agile 4 score, although it missed more LREs in the low-risk group. Conclusions and Relevance: Findings of this study suggest that single or serial Agile scores are highly accurate in predicting LREs in patients with MASLD, making them suitable alternatives to liver biopsy in routine clinical practice and in phase 2b and 3 clinical trials for steatohepatitis.

PURPOSE: To compare the treatment outcomes of glass and resin microspheres for the treatment of hepatocellular carcinoma (HCC) and evaluate the prognostic factors that influence the outcomes. MATERIALS AND METHODS: We retrospectively reviewed 251 consecutive patients who underwent radioembolization for the treatment of HCC at a single tertiary center. Imaging responses after radioembolization were evaluated using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) 1.1. Progression-free survival (PFS) and overall survival (OS) were analyzed using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard models were used to identify the prognostic factors. RESULTS: A total of 195 patients were included in this study (glass microsphere, n = 75; resin microsphere, n = 120). The complete and objective response rates were 16.0% and 50.7% in the glass microsphere group and 17.5% and 58.3% in the resin microsphere group, respectively. Median PFS was 241 days in the glass microsphere group and 268 days in the resin microsphere group (p = 0.871). Median OS was 29 months in the glass microsphere group and 40 months in the resin microsphere group (p = 0.669). The only significant prognostic factor was bilobar tumor distribution, which favored resin microspheres (p = 0.023). Procedure-related adverse events occurred more frequently in the resin microsphere group (glass, 2.7% vs. resin, 5.0%; p < 0.001). CONCLUSION: Glass and resin microspheres for the treatment of HCC did not show a significant difference in survival, though major adverse events occurred more frequently with the use of resin microspheres.
RESUMO
BACKGROUND AND AIMS: Despite the development of transient elastography (TE)-based Agile scores for diagnosing fibrotic burden in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), their applicability in predicting kidney outcomes remains unclear. We aimed to investigate the association between liver fibrotic burden, as assessed by Agile scores, and the risk of incident chronic kidney disease (CKD) in patients with MASLD. METHODS: A total of 3240 participants with MASLD but without pre-existing CKD who underwent TE between July 2006 and October 2018 were selected. The primary outcome was incident CKD, defined as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 or proteinuria (≥1+ on dipstick) on two consecutive measurements. The secondary outcome was a 25% decline in eGFR measured on two consecutive visits. RESULTS: During a median follow-up of 3.6 years, 187 participants (5.8%) developed incident CKD. When stratified into three groups according to Agile 3+ scores, multivariable Cox models revealed that risk of incident CKD was 2.77-fold (95% confidence interval [CI], 1.89-4.07; p < 0.001) higher in the high-risk group (Agile 3+ >0.68), compared to the low-risk group (Agile 3+ <0.45). During a median follow-up of 3.4 years, the high-risk group had a 2.41-fold higher risk (95% CI, 1.86-3.12; p < 0.001) of experiencing the secondary outcome, compared to the low-risk group. Similar findings were observed for Agile 4 scores. Prediction testing revealed that Agile scores were better predictors of kidney outcomes, compared to liver stiffness measured by TE. CONCLUSIONS: In patients with MASLD, but without CKD, advanced liver fibrosis measured by Agile scores was significantly associated with a higher risk of incident CKD.
RESUMO
BACKGROUND: A new fatty liver disease nomenclature, steatotic liver disease (SLD) has been proposed; however, there are no data on clinical outcomes. We investigated the impact of SLD with metabolic dysfunction (MD; SLD-MD) on all-cause mortality. METHODS: We evaluated nationally representative participants aged ≥19 years using data from the Korea National Health and Nutrition Examination Survey 2007-2015 and their linked death data through 2019. The presence of fatty liver disease was assessed by liver fat score, fatty liver index and significant liver fibrosis was evaluated by the Fibrosis-4 Index, and fibrosis score. SLD-MD was categorized into three groups: metabolic dysfunction-associated steatotic liver disease (MASLD); metabolic alcoholic liver disease (MetALD); and SLD with other combination etiologies. RESULTS: Among 26734 individuals (11561 men and 15173 women, mean age 48.8 years), 1833 (6.9 %) died during a mean follow-up period of 110.6 ± 33.9 months. Mortality risk was significantly higher in individuals with SLD-MD (hazard ratio [HR] = 1.35) than in those without (P < 0.001). Among the three groups, MASLD (HR = 1.32) and SLD with other combination etiologies (HR = 2.06) independently increased mortality risk (all P < 0.001). When individuals with SLD-MD had significant liver fibrosis or diabetes, mortality risk increased further (HR = 1.68 and 1.85, respectively; all P < 0.001). SLD-MD with both significant liver fibrosis and diabetes showed the highest mortality risk (HR = 2.29, P < 0.001). When applied fatty liver index and fibrosis score, similar results were observed. CONCLUSIONS: SLD-MD is associated with a higher mortality risk. When SLD-MD was combined with significant liver fibrosis or diabetes, the mortality risk became much higher. Treatment strategies to reduce fibrotic burden and improve glycemic control in individuals with MASLD are needed.

BACKGROUND: Behçet's disease (BD) and nonalcoholic fatty liver disease (NAFLD) are chronic inflammatory diseases that share pathogenetic mechanisms. In this study, we investigated whether NAFLD influences the clinical outcomes in patients with intestinal BD. METHODS: Patients with intestinal BD and available hepatic steatosis index (HSI) and fibrosis-4 (FIB-4) scores were recruited between 2005 and 2022. An HSI of ≥30 and FIB-4 of ≥1.45 were used to diagnose hepatic steatosis and significant liver fibrosis, respectively. The primary outcomes were intestinal BD-related hospitalization, surgery, emergency room visits, or the first use of corticosteroids, immunomodulators, or biologic agents for intestinal BD. RESULTS: A total of 780 patients with BD were selected. The prevalence of hepatic steatosis and significant liver fibrosis were 72.3% and 8.8%, respectively. Multivariate analysis showed that younger age, prior smoking history, concomitant skin lesions, higher white blood cell count, and lower serum albumin levels were independently associated with an increased risk of clinical relapse (all Pâ <â 0.05), whereas hepatic steatosis and significant liver fibrosis were not (hazard ratio [HR]â =â 1.164, 95% confidence interval [CI] 0.923-1.468; Pâ =â 0.199 for hepatic steatosis; HRâ =â 0.982, 95% CI 0.672-1.436; Pâ =â 0.927 for significant liver fibrosis). CONCLUSION: Hepatic steatosis and liver fibrotic burden were not independently associated with clinical outcomes in patients with intestinal BD.

PURPOSE: Nivolumab and regorafenib are second-line therapies for patients with advanced hepatocellular carcinoma (HCC). We aimed to compare the effectiveness of nivolumab and regorafenib. MATERIALS AND METHODS: We retrospectively reviewed patients with HCC treated with nivolumab or regorafenib after sorafenib failure. Progression-free survival (PFS) and overall survival (OS) were analyzed. An inverse probability of treatment weighting using the propensity score (PS) was performed to reduce treatment selection bias. RESULTS: Among the 189 patients recruited, 137 and 52 patients received regorafenib and nivolumab after sorafenib failure, respectively. Nivolumab users showed higher Child-Pugh B patients (42.3% vs. 24.1%) and shorter median sorafenib maintenance (2.2 months vs. 3.5 months) compared to regorafenib users. Nivolumab users showed shorter median OS (4.2 months vs. 7.4 months, p=0.045) than regorafenib users and similar median PFS (1.8 months vs. 2.7 months, p=0.070). However, the median overall and PFS did not differ between the two treatment groups after the 1:1 PS matching (log-rank p=0.810 and 0.810, respectively) and after the stabilized inverse probability of treatment weighting (log-rank p=0.445 and 0.878, respectively). In addition, covariate-adjusted Cox regression analyses showed that overall and PFS did not significantly differ between nivolumab and regorafenib users after 1:1 PS matching and stabilized inverse probability of treatment weighting (all p>0.05). CONCLUSION: Clinical outcomes of patients treated with nivolumab and regorafenib after sorafenib treatment failure did not differ significantly.

Background & Aims: The association between hepatitis B envelope antigen (HBeAg) seroclearance during long-term nucleos(t)ide analogue (NA) treatment and the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB) remains unclear. Here, we aimed to investigate the association of HBeAg seroclearance during potent NA treatment with the development of HCC and decompensated cirrhosis. Methods: Using a multicenter historical cohort including 2,392 non-cirrhotic adult patients with HBeAg-positive CHB who initiated NA treatment with tenofovir or entecavir, the risk of HCC and decompensated cirrhosis was compared between patients who achieved HBeAg seroclearance within 36 months of NA treatment (the HBeAg-loss group) and those who did not (the HBeAg-maintained group), using inverse probability of treatment weighting. Results: Over a median of 6.6 years of NA treatment, 1,077 patients achieved HBeAg seroclearance (HBeAg loss rate = 6.0 per 100 person-years), 64 patients developed HCC (HCC incidence rate = 0.39 per 100 person-years), and 46 patients developed decompensated cirrhosis (decompensation incidence rate = 0.28 per 100 person-years). The HBeAg-loss and HBeAg-maintained groups had a similar risk of developing HCC (hazard ratio 0.89; 95% CI 0.47-1.68; p = 0.72) and decompensated cirrhosis (hazard ratio 0.98; 95% CI 0.48-1.81; p = 0.91). Compared with delayed HBeAg seroclearance beyond 10 years of NA treatment, the risk of HCC was comparable in those who achieved earlier HBeAg seroclearance at any time point within 10 years, regardless of baseline age and fibrotic burden. Conclusions: Early HBeAg seroclearance during NA treatment was not associated with a reduced risk of development of HCC or decompensated cirrhosis in non-cirrhotic HBeAg-positive patients with CHB. Impact and implications: The association between hepatitis B envelope antigen (HBeAg) seroclearance during long-term nucleos(t)ide analogue treatment and the risk of hepatocellular carcinoma in patients with chronic hepatitis B remains unclear. Our findings indicate that early on-treatment HBeAg seroclearance within 3 years was not associated with the development of hepatocellular carcinoma or decompensated cirrhosis. Achieving HBeAg seroclearance may not be an appropriate surrogate endpoint for preventing the development of liver-related outcomes in non-cirrhotic patients with HBeAg-positive chronic hepatitis B treated with nucleos(t)ide analogues.
RESUMO
Background/aims: Opinions differ regarding transient elastography and magnetic resonance elastography (TE/MRE) cut-offs for diagnosing advanced fibrosis (AF) in patients with non-alcoholic fatty liver disease (NAFLD). We investigated the diagnostic performance and optimal cut-off values of TE and MRE for diagnosing AF. Methods: Literature databases, including Medline, EMBASE, Cochrane Library, and KoreaMed, were used to identify relevant studies published up to June 13, 2023. We selected studies evaluating TE and MRE regarding the degree of liver fibrosis using liver biopsy as the reference. The sensitivity, specificity, and area under receiver operating characteristics curves (AUCs) of the pooled data for TE and MRE for each fibrosis stage and optimal cut-offs for AF were investigated. Results: A total of 19,199 patients from 63 studies using TE showed diagnostic AUC of 0.83(95% confidence interval: 0.80-0.86), 0.83(0.80-0.86), 0.87(0.84-0.90), and 0.94(0.91-0.96) for ≥F1, ≥F2, ≥F3, and F4 stages, respectively. Similarly, 1,484 patients from 14 studies using MRE showed diagnostic AUC of 0.89(0.86-0.92), 0.92(0.89-0.94), 0.89(0.86-0.92), and 0.94(0.91-0.96) for ≥F1, ≥F2, ≥F3, and F4 stages respectively. The diagnostic AUC for AF using TE was highest at 0.90 with a cut-off of 7.1-7.9 kPa, and that of MRE was highest at 0.94 with a cut-off of 3.62-3.8 kPa. Conclusions: TE(7.1-7.9 kPa) and MRE(3.62-3.8 kPa) with the suggested cut-offs showed favorable accuracy for diagnosing AF in patients with NAFLD. This result will serve as a basis for clinical guidelines for non-invasive tests and differential diagnosis of AF.
RESUMO
Background and Aims: This meta-analysis examined whether preoperative vibration-controlled transient elastography (VCTE) can predict postoperative complications and recurrence in patients undergoing hepatic resection for hepatocellular carcinoma (HCC). Methods: A systematic literature search was conducted using Ovid-Medline, EMBASE, Cochrane, and KoreaMed databases. Out of 431 individual studies, thirteen published between 2008 and 2022 were included. Five studies focused on HCC recurrence, while eight examined postoperative complications. Results: The meta-analysis of five studies on HCC recurrence showed that the high-risk group with a high VCTE score had a significantly increased recurrence rate after hepatic resection (hazard ratio [HR], 2.14). The cutoff value of VCTE in the high-risk group of HCC recurrence was 7.4-13.4kPa, the sensitivity was 0.60 (95% CI 0.47-0.72), and the specificity was 0.60 (95% CI 0.46-0.72). The area under the receiver operating characteristic curve (AUC) of the liver stiffness measured by VCTE to predict the HCC recurrence was 0.63 (95% CI 0.59-0.67). The meta-analysis on the postoperative complications revealed a significantly increased risk of postoperative complications in the high-risk group (12-25.6kPa) with a high VCTE value (risk ratio [RR], 8.32). The AUC of the liver stiffness measured by VCTE to predict the postoperative complications was 0.87(95% CI 0.84-0.90), the sensitivity was 0.76 (95% CI 0.55-0.89) and the specificity was 0.85 (95% CI 0.73-0.92). Conclusions: This meta-analysis suggests that preoperative VCTE in patients undergoing hepatic resection for HCC is useful in identifying individuals at a high risk of postoperative complications and HCC recurrence.
RESUMO
Background/Aims: The assessment of liver fibrosis is crucial for managing autoimmune liver diseases such as primary biliary cholangitis (PBC), autoimmune hepatitis (AIH), and primary sclerosing cholangitis (PSC). However, data on the efficacy of noninvasive tests (NITs) for these diseases are limited. This meta-analysis evaluated the diagnostic accuracy of vibration-controlled transient elastography (VCTE) for staging fibrosis in patients with autoimmune liver disease. Methods: Searches were conducted in PubMed, Embase, CINAHL, Web of Science, and Cochrane Library databases to assess the diagnostic accuracy of VCTE against histology as the reference standard in adult patients with autoimmune liver disease. The summary area under the curve (sAUC) and diagnostic odds ratio were calculated for significant fibrosis (SF), advanced fibrosis (AF), and cirrhosis, defined as METAVIR stages F≥2, F≥3, and F=4, respectively, according to liver biopsy. Results: Fourteen articles were included, comprising 559 PBC patients from six studies, 388 AIH patients from five studies, and 151 PSC patients from three studies. VCTE demonstrated good performance for fibrosis staging in PBC, AIH, and PSC. In PBC, sAUCs of VCTE were 0.87 (95% confidence interval, 0.80-0.94), 0.89 (0.85-0.94), and 0.99 (0.96-1.00) for staging SF, AF, and cirrhosis, respectively. In AIH, the sAUCs were 0.88 (0.84-0.92), 0.88 (0.83-0.93), and 0.92 (0.88-0.96), respectively, while in PSC, they were 0.88 (0.82-0.95), 0.95 (0.90-1.00), and 0.92 (0.84-0.99), respectively. The cutoff values for AF were 7.5-17.9 kPa in PBC, 8.18-12.1 kPa in AIH, and 9.6 kPa in PSC. Conclusions: VCTE shows high diagnostic accuracy for staging liver fibrosis in patients with autoimmune liver diseases such as PBC, AIH, and PSC. This non-invasive and reliable method serves as a valuable tool for the evaluation and monitoring of fibrosis in these lifelong diseases.
RESUMO
Background: Despite advances in antiviral therapy for hepatitis C virus (HCV) infection, hepatocellular carcinoma (HCC) still develops even after sustained viral response (SVR) in patients with advanced liver fibrosis or cirrhosis. This meta-analysis investigated the predictive performance of transient elastography (TE) and fibrosis 4-index (FIB-4) for the development of HCC after SVR. Methods: We searched PubMed, MEDLINE, EMBASE, and the Cochrane Library for studies examining the predictive performance of these tests in adult patients with HCV. Two authors independently screened the studies' methodological quality and extracted data. Pooled estimates of sensitivity, specificity, and area under the curve (AUC) were calculated for HCC development using random-effects bivariate logit normal and linear-mixed effect models. Results: We included 27 studies (169,911 patients). Meta-analysis of HCC after SVR was possible in nine TE and 15 FIB-4 studies. Regarding the prediction of HCC development after SVR, the pooled AUCs of pre-treatment TE >9.2-13 kPa and FIB-4 >3.25 were 0.79 and 0.73, respectively. TE >8.4-11 kPa and FIB-4 >3.25 measured after SVR, maintained good predictive performance, albeit slightly reduced (pooled AUCs: 0.77 and 0.70, respectively). The identified optimal cut-off value for HCC development after SVR was 12.6 kPa for pre-treatment TE. That of TE measured after the SVR was 11.2 kPa. Conclusion: TE and FIB-4 showed acceptable predictive performance for HCC development in patients with HCV who achieved SVR, underscoring their utility in clinical practice for guiding surveillance strategies. Future studies are needed to validate these findings prospectively and validate their clinical impact.
RESUMO
Background/Aims: Although important, clinically significant liver fibrosis is often overlooked in the general population. We aimed to examine the prevalence of clinically significant liver fibrosis using noninvasive tests (NITs) in the general population. Methods: We collected data from four databases (MEDLINE, Embase, Cochrane Library, and KoreaMed) from inception to June 13, 2023. Original articles reporting the prevalence of clinically significant liver fibrosis in the general population were included. The Stata metaprop function was used to obtain the pooled prevalence of liver fibrosis with NITs in the general population. Results: We screened 6,429 articles and included 45 eligible studies that reported the prevalence of clinically significant liver fibrosis in the general population. The prevalence of advanced liver fibrosis, using the high probability cutoff of the fibrosis-4 (FIB-4) index, was 2.3% (95% confidence interval [CI], 1.2-3.7%). The prevalence of significant liver fibrosis, advanced liver fibrosis, and liver cirrhosis, assessed using vibration-controlled transient elastography (VCTE) among the general population, was 7.3% (95% CI, 5.9-8.8%), 3.5% (95% CI, 2.7-4.5), and 1.2% (95% CI, 0.8-1.8%), respectively. Region-based subgroup analysis revealed that the highest prevalence of advanced fibrosis using the high probability cutoff of the FIB-4 index was observed in the American region. Furthermore, the American region exhibits the highest prevalence of significant liver fibrosis, advanced liver fibrosis, and liver cirrhosis, using VCTE. Conclusions: Previously undiagnosed clinically significant liver fibrosis is found in the general population through NITs. Future research is necessary to stratify the risk in the general population.
RESUMO
Background and Aims: Liver stiffness measurement (LSM) using transient elastography (TE) can assess fibrotic burden in chronic liver diseases. The systematic review and meta-analysis was conducted to determine whether LSM using TE can predict the risk of development of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients. Methods: A systematic literature search of the Ovid-Medline, EMBASE, Cochrane, and KoreaMed databases (from January 2010 to June 2023) was conducted. Of the 1,345 individual studies identified, 10 studies that used TE were finally registered. Hazard ratios (HRs) and the 95% conï¬dence interval (CIs) were considered summary estimates of treatment effect sizes of ≥ 11 kilopascal (kPa) standard for HCC development. Meta-analysis was performed using the restricted Maximum Likelihood random effects model. Results: Among the ten studies, data for risk ratios for HCC development could be obtained from nine studies. When analyzed for the nine studies, the HR for HCC development was high at 3.33 (95% CI, 2.45-4.54) in CHB patients with a baseline LSM of ≥ 11 kPa compared to patients who did not. In ten studies included, LSM of ≥ 11 kPa showed the sensitivity and specificity for predicting HCC development were 61% (95% CI, 50-71%) and 78% (95% CI, 66-86%), respectively, and the diagnostic accuracy was 0.74 (95% CI, 0.70-0.77). Conclusions: The risk of HCC development was elevated in CHB patients with TE-determined LSM of ≥11 kPa. This finding suggests that TE-determined LSM values may aid the risk prediction of HCC development in CHB patients.
RESUMO
Background and Aims: Accurate diagnosis of significant liver fibrosis in patients with chronic hepatitis B (CHB) is crucial when determining whether to initiate antiviral treatment (AVT). We conduct a meta-analysis to assess the diagnostic performance of transient elastography (TE) for significant liver fibrosis in AVT-naïve CHB patients with serum alanine transaminase (ALT) levels within 5-fold the upper limit of normal (ULN). Methods: The Ovid-Medline, EMBASE, Cochrane, and KoreaMed databases were searched to identify studies that compared the performance of TE and liver biopsy (reference standard) when diagnosing significant liver fibrosis (≥ F2) in AVT-naïve CHB patients with ALT within 5-fold the ULN. A hierarchical summary receiver operating characteristic curve (HSROC) and bivariate model were performed to evaluate the diagnostic performance of TE in the meta-analysis. Results: Eight studies (2,003 patients) were included. The summary sensitivity and specificity for diagnosis of significant liver fibrosis were 0.78 [95% confidence interval (CI), 0.66-0.86] and 0.72 (95% CI, 0.60-0.82), respectively. The HSROC for the diagnosis of significant liver fibrosis was 0.81 (95% CI, 0.72-0.86). The optimal cut-off value of TE for diagnosis of significant liver fibrosis was 7.7 kPa with a sensitivity of 0.64 (95% CI, 0.50-0.76) and specificity of 0.83 (95% CI, 0.72-0.90). Conclusions: Our study demonstrated that TE has an acceptable diagnostic performance for significant liver fibrosis in AVT-naïve CHB patients with ALT within 5-fold the ULN.
RESUMO
Background/Aims: The Fibrosis-4 index (FIB-4) is a non-invasive test widely used to rule out advanced liver fibrosis (AF) in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). However, its diagnostic accuracy in MASLD patients with type 2 diabetes mellitus (T2DM) are controversial due to the high prevalence of AF in this population. Methods: Research focusing on the diagnostic accuracy of FIB-4 for liver fibrosis as validated by liver histology in MASLD patients with T2DM was included, and 12 studies (n=5,624) were finally included in the meta-analysis. Sensitivity, specificity, hierarchical summary receiver operating characteristic (HSROC), positive predictive values (PPVs), and negative predictive values (NPVs) at low cutoffs (1.3-1.67) and high cutoffs (2.67-3.25) for ruling in and out AF, were calculated. Results: At low cutoffs, the meta-analysis revealed a sensitivity of 0.74, specificity of 0.62, and HSROC of 0.75. At high cutoffs, the analysis showed a sensitivity of 0.33, specificity of 0.92, and HSROC of 0.85, suggesting FIB-4 as useful for identifying or excluding AF. In subgroup analyses, high mean age and F3 prevalence were associated with lower sensitivity. The calculated NPV and PPV were 0.82 and 0.49 at low cutoffs, whereas the NPV was 0.28 and the PPV was 0.70 at high cutoffs. There were insufficient estimated NPVs <0.90 at a hypothesized prevalence of AF >30% at an FIB-4 cutoff range of 1.3-1.67. Conclusions: Collectively, FIB-4 has moderate diagnostic accuracy for identifying or excluding AF in MASLD patients with T2DM, but more evidence must be accumulated due to the limited number of currently reported studies and their heterogeneity.
RESUMO
BACKGROUND: Proton pump inhibitors (PPI) are frequently used in patients with cirrhosis. AIMS: This study aimed to determine whether PPI use is associated with the prognosis of cirrhotic patients. METHODS: We conducted a multicentre retrospective cohort study involving 1485 patients who had experienced hepatic encephalopathy (HE) from 7 referral centres in Korea. The primary outcome was overall survival and secondary outcomes included the development of cirrhotic complications, including recurrent HE, spontaneous bacterial peritonitis (SBP), hepatorenal syndrome (HRS), and gastrointestinal bleeding. Patients treated with PPI with a mean defined daily dose (mDDD) ≥0.5 (high-dose PPI group) were compared to those treated with PPI of an mDDD < 0.5 (No or low-dose PPI group) for each outcome. RESULTS: Among 1485 patients (median age, 61 years; male, 61%), 232 were assigned to the high-dose PPI group. High-dose PPI use was independently associated with a higher risk of death (adjusted HR [aHR] = 1.71, 95% confidence interval [CI] = 1.38-2.11, p < 0.001). This result was reproducible after propensity score-matching (PSM) (aHR = 1.90, 95% CI = 1.49-2.44, p < 0.001). High-dose PPI use was an independent risk factor of recurrent HE (before PSM: aHR = 2.04, 95% CI = 1.66-2.51, p < 0.001; after PSM: aHR = 2.16, 95% CI = 1.70-2.74, p < 0.001), SBP (before PSM: aHR = 1.87, 95% CI = 1.43-2.43, p < 0.001; after PSM: aHR = 1.76, 95% CI = 1.31-2.36, p = 0.002), HRS (before PSM: aHR = 1.48, 95% CI = 1.02-2.15, p = 0.04; after PSM: aHR = 1.47, 95% CI = 0.95-2.28, p = 0.09), and gastrointestinal bleeding (before PSM: aHR = 1.46, 95% CI = 1.12-1.90, p = 0.006; after PSM: aHR = 1.74, 95% CI = 1.28-2.37, p < 0.001). CONCLUSIONS: The use of high-dose PPI was independently associated with increased risks of mortality and cirrhotic complications.

BACKGROUND/AIMS: Atezolizumab plus bevacizumab (ATE+BEV) therapy has become the recommended first-line therapy for patients with unresectable hepatocellular carcinoma (HCC) because of favorable treatment responses. However, there is a lack of data on sequential regimens after ATE+BEV treatment failure. We aimed to investigate the clinical outcomes of patients with advanced HCC who received subsequent systemic therapy for disease progression after ATE+BEV. METHODS: This multicenter, retrospective study included patients who started second-line systemic treatment with sorafenib or lenvatinib after HCC progressed on ATE+BEV between August 2019 and December 2022. Treatment response was assessed using the Response Evaluation Criteria in Solid Tumors (version 1.1.). Clinical features of the two groups were balanced through propensity score (PS) matching. RESULTS: This study enrolled 126 patients, 40 (31.7%) in the lenvatinib group, and 86 (68.3%) in the sorafenib group. The median age was 63 years, and males were predominant (88.1%). In PS-matched cohorts (36 patients in each group), the objective response rate was similar between the lenvatinib- and sorafenib-treated groups (5.6% vs. 8.3%; P=0.643), but the disease control rate was superior in the lenvatinib group (66.7% vs. 22.2%; P<0.001). Despite the superior progression- free survival (PFS) in the lenvatinib group (3.5 vs. 1.8 months, P=0.001), the overall survival (OS, 10.3 vs. 7.5 months, P=0.353) did not differ between the two PS-matched treatment groups. CONCLUSION: In second-line therapy for unresectable HCC after ATE+BEV failure, lenvatinib showed better PFS and comparable OS to sorafenib in a real-world setting. Future studies with larger sample sizes and longer follow-ups are needed to optimize second-line treatment.
