Predicting response to non-selective beta-blockers with liver-spleen stiffness and heart rate in patients with liver cirrhosis and high-risk varices

INTRODUCTION

Non-selective beta-blockers (NSBB) are used for primary prophylaxis in patients with liver cirrhosis and high-risk varices (HRVs). Assessing therapeutic response is challenging due to the invasive nature of hepatic venous pressure gradient (HVPG) measurement. This study aims to define a noninvasive machine-learning based approach to determine response to NSBB in patients with liver cirrhosis and HRVs.

METHODS

We conducted a prospective study on a cohort of cirrhotic patients with documented HRVs receiving NSBB treatment. Patients were followed-up with clinical and elastography appointments at 3, 6, and 12 months after NSBB treatment initiation. NSBB response was defined as stationary or downstaging variceal grading at the 12-month esophagogastroduodenoscopy (EGD). In contrast, non-response was defined as upstaging variceal grading at the 12-month EGD or at least one variceal hemorrhage episode during the 12-month follow-up. We chose cut-off values for univariate and multivariate model with 100% specificity.

RESULTS

According to least absolute shrinkage and selection operator (LASSO) regression, spleen stiffness (SS) and liver stiffness (LS) percentual decrease, along with changes in heart rate (HR) at 3 months were the most significant predictors of NSBB response. A decrease > 11.5% in SS, > 16.8% in LS, and > 25.3% in HR was associated with better prediction of clinical response to NSBB. SS percentual decrease showed the highest accuracy (86.4%) with high sensitivity (78.8%) when compared to LS and HR. The multivariate model incorporating SS, LS, and HR showed the highest discrimination and calibration metrics (AUROC = 0.96), with the optimal cut-off of 0.90 (sensitivity 94.2%, specificity 100%, PPV 95.7%, NPV 100%, accuracy 97.5%).

A systematic review of noninvasive laboratory indices and elastography to predict hepatic decompensation

BACKGROUND

Hepatic decompensation carries profound implications for patient quality of life and risk of mortality. We lack comparative data on how noninvasive tools perform in risk stratification for those with compensated cirrhosis. We performed a systematic review to assess the performance of laboratory and transient elastography-based models for predicting hepatic decompensation in patients with compensated cirrhosis.

METHODS

The following databases were searched by an informationist to identify relevant studies, including adult patients with compensated cirrhosis from inception to August 2023: Medline, Embase, Scopus, Web of Science, and ClinicalTrials.gov. Title and abstract screening followed by full-text review were performed by 2 independent reviewers, and data abstraction was completed using standardized forms. Studies of patients with decompensation at baseline (defined by ascites, variceal bleeding, and HE) or any primary hepatic malignancy were excluded. The primary outcome was hepatic decompensation, as defined above. Pooled HRs were calculated using the common-effect inverse-variance model.

RESULTS

Forty-four full-text studies met the inclusion criteria. Across 52,589 patients, the cumulative incidence of any decompensation was 17.9% over a follow-up time of 111,401 patient years. Pooled risk estimates for all-cause decompensation demonstrated that MELD (HR: 1.08; 95% CI: 1.06-1.10), albumin-bilirubin (HR: 2.13, 95% CI: 1.92-2.36), fibrosis-4 (HR: 1.04, 95% CI: 1.03-1.06), albumin-bilirubin-fibrosis-4 (HR: 1.25, 95% CI: 1.18-1.33), and liver stiffness by transient elastography (HR: 1.04; 95% CI: 1.04-1.05) predict decompensation.

CONCLUSIONS

Available blood and imaging-based biomarkers can risk-stratify patients for hepatic decompensation. Changes in albumin-bilirubin appear to have the highest discrimination in predicting decompensation events.

Predictive model for HBsAg clearance rate in chronic hepatitis B patients treated with pegylated interferon α-2b for 48 weeks

BACKGROUND AND AIMS

Chronic hepatitis B (CHB) is a major global health concern. This study aims to investigate the factors influencing hepatitis B surface antigen (HBsAg) clearance in CHB patients treated with pegylated interferon α-2b (Peg-IFNα-2b) for 48 weeks and to establish a predictive model.

METHODS

This analysis is based on the "OASIS" project, a prospective real-world multicenter study in China. We included CHB patients who completed 48 weeks of Peg-IFNα-2b treatment. Patients were randomly assigned to a training set and a validation set in a ratio of approximately 4:1 by spss 26.0, and were divided into clearance and non-clearance groups based on HBsAg status at 48 weeks. Clinical data were analyzed using SPSS 26.0, employing chi-square tests for categorical data and Mann-Whitney U tests for continuous variables. Significant factors (p < 0.05) were incorporated into a binary logistic regression model to identify independent predictors of HBsAg clearance. The predictive model's performance was evaluated using ROC curve analysis.

RESULTS

We included 868 subjects, divided into the clearance group (187 cases) and the non-clearance group (681 cases). They were randomly assigned to a training set (702 cases) and a validation set (166 cases). Key predictors included female gender (OR = 1.879), lower baseline HBsAg levels (OR = 0.371), and cirrhosis (OR = 0.438). The final predictive model was: Logit(P) = 0.92 + Gender (Female) * 0.66 - HBsAg (log) * 0.96 - Cirrhosis * 0.88. ROC analysis showed an AUC of 0.80 for the training set and 0.82 for the validation set, indicating good predictive performance.

CONCLUSION

Gender, baseline HBsAg levels, and cirrhosis are significant predictors of HBsAg clearance in CHB patients after 48 weeks of Peg-IFNα-2b therapy. The developed predictive model demonstrates high accuracy and potential clinical utility.

Recompensation of Liver Cirrhosis by TIPS Reduces Epithelial Cell Death Markers, Translating Into Improved Clinical Outcome

BACKGROUND AND AIMS

Portal hypertension is the main pathophysiological driver of decompensation in patients with liver cirrhosis. Epithelial cell death markers, m30 and m65, correlate with hepatic injury and predict outcomes across various stages of liver disease. We aim (i) to evaluate whether portal hypertension itself contributes to liver outcome-relevant epithelial injury, and (ii) to analyse the capacity of m30/m65 to predict outcome in patients receiving a transjugular intrahepatic portosystemic shunt (TIPS) for refractory ascites.

METHODS

Sixty-six patients undergoing TIPS placement for refractory ascites and 20 patients with compensated cirrhosis as controls were prospectively enrolled in this monocentric cohort study. Epithelial cell death markers were analysed pre-TIPS, as well as 1-3 and 6-9 months post-TIPS. The capacity of baseline levels of m30/m65 in predicting six-month transplant-free survival rates was analysed by multivariable Cox proportional hazards regression.

RESULTS

Levels of m30 and m65 were higher in patients with decompensated cirrhosis (pre-TIPS) compared with compensated cirrhosis (controls). Following correction of portal hypertension by TIPS and recompensation, both markers decreased over time, reaching levels comparable to patients with compensated cirrhosis. On multivariable analysis, pre-TIPS baseline levels of m30 and m65 were not predictive for six-month survival.

CONCLUSION

Correction of portal hypertension via TIPS reduces levels of epithelial cell death markers, indicating that portal hypertension is a driver of outcome-relevant, hepatic cell death in patients with decompensated cirrhosis. Baseline m30/m65 values do not affect six-month survival rates, which suggests that TIPS placement overcomes the unfavourable spontaneous prognosis otherwise indicated by elevated baseline m30/65 levels.

Exploring the Relationship Between NOD2 Risk Variants and First Decompensation Events in Cirrhotic Patients With Varices

BACKGROUND AND AIMS

NOD2 mutations are associated with impaired gut mucosal barrier function. According to the systemic inflammation hypothesis, bacterial translocation is central in the development of decompensation. The aim was to evaluate whether the presence of NOD2 variants is associated with the development of first decompensation.

METHOD

Secondary analysis of prospectively collected consecutive patients with compensated cirrhosis, who were screened between 2014 and 2018. Patients with and without NOD2 variants were compared and stratified analysis according to the presence of varices was performed.

RESULTS

360 patients [239 (66%) men, median age 61 (53-69) years, 70 (19%) with NOD2 variants, 90 (25%) with varices] were followed for a median of 9 (4-16) months. Similar baseline characteristics were observed across NOD2 status groups, except for beta-blocker use (45% vs. 32% amongst variant carriers vs. non-carriers, p = 0.05). During follow-up, 34 patients (12%) developed their first decompensation, with no differences according to NOD2 status [HR 1.75 (95% CI 0.84-3.67)]. On multivariate analysis, only MELD remained an independent predictor of decompensation. Amongst patients with varices (n = 90), 18 (24.4%) carried a NOD2 variants, with a higher incidence of first decompensation [HR 3.00 (95% CI 1.08-8.32)], primarily due to ascites [HR 3.32 (95% CI 1.07-10.32)]. In this subgroup, MELD [HR 1.18 (95% CI 1.06-1.32)] and NOD2 variants [HR 2.91 (95% CI 0.95-8.89)] were determined to be independent predictors of decompensation.

CONCLUSIONS

The presence of NOD2 risk variants leads to a greater incidence of first decompensation only in compensated patients with varices.

Approach to steatotic liver disease in the office: Diagnosis, management, and proposed nomenclature

OBJECTIVE

To provide an update on the most recent developments regarding diagnosis and outcomes of steatotic liver disease (SLD), review new nomenclature applied to SLD, and provide an approach to the diagnosis and management of SLD.

SOURCES OF INFORMATION

Individual articles published mainly in the past 2 years, found using PubMed and Google Scholar.

MAIN MESSAGE

Steatotic liver disease is one of the most common diseases encountered in general practice. This condition is an important biological marker for metabolic syndrome. Diagnosis relies on noninvasive tests. Known complications of metabolic syndrome and advanced liver disease are often present at the time of diagnosis. Courses of action should include assessment of cardiometabolic risk factors and progressive liver dysfunction. Subtle differences are present among patients diagnosed with SLD. Practitioners should be aware of a flux in terminology of SLD. Management of SLD can be guided using a simple algorithm.

CONCLUSION

There is a need for evaluation of the SLD epidemic and its systemic nature, along with associated independent risk factors of cardiovascular disease as well as metabolic conditions such as dyslipidemia, hypertension, and type 2 diabetes.

APAGE Position Statements on Green and Sustainability in Gastroenterology, Hepatology, and Gastrointestinal Endoscopy

BACKGROUND AND AIM

The APAGE Position Statements aimed to provide guidance to healthcare practitioners on clinical practices aligned with climate sustainability.

METHODS

A taskforce convened by APAGE proposed provisional statements. Twenty-two gastroenterologists from the Asian Pacific region participated in online voting and consensus was assessed through an anonymized and iterative Delphi process.

RESULTS

There were five sections that addressed the rationale for climate action, the importance of adopting principles of waste management, clinical practice, gastrointestinal endoscopy, and issues related to advocacy and research. Sixteen statements achieved consensus and included the following: 1. APAGE recommends adopting prompt measures to reduce the carbon footprint of clinical practice due to the importance of climate action and its health cobenefits. 5. APAGE recommends adherence to professional clinical guidelines to optimize clinical care delivery in gastroenterology and hepatology to avoid the environmental impact of unnecessary procedures and tests. 8. APAGE recommends an emphasis on health promotion, disease prevention, and appropriate screening and surveillance, when resources are available, to reduce the environmental impact of managing more advanced diseases that require more intensive resources. 12. APAGE recommends that technological advances in endoscopic imaging and artificial intelligence, when available, be used to improve the precision of endoscopic diagnosis to reduce the risk of missed lesions and need for unnecessary biopsies. 13. APAGE recommends against the routine use of single-use endoscopes.

CONCLUSION

The position statements provide guidance to healthcare practitioners on clinical practices in gastroenterology, hepatology, and endoscopy that promote climate sustainability.

Decreasing interleukin-6 levels after TIPS predict outcomes in decompensated cirrhosis

Background & Aims

Transjugular intrahepatic portosystemic shunt (TIPS) effectively treats complications of cirrhosis. Systemic inflammation (SI) is linked to acute-on-chronic liver failure (ACLF) and liver-related death. We aimed to assess the trajectory and clinical impact of SI parameters after TIPS implantation.

Methods

Consecutive patients undergoing elective implantation of covered TIPS for recurrent/refractory ascites or portal-hypertensive bleeding at the Medical University Vienna (NCT03409263; n = 58) and at the Hannover Medical School (NCT04801290, n = 51) were included. IL-6 was assessed at baseline (BL), 3 months (M3) and up to 6 (M6; Hannover cohort) or 9 months (M9; Vienna cohort) of follow-up; C-reactive protein (CRP) and lipopolysaccharide-binding protein (LBP) were assessed in the Vienna cohort only.

Results

In 109 patients (66.1% male, median age 57 years) receiving TIPS mainly (72.4%) by indication ascites the median BL IL-6 levels were 10.5 pg/ml; and 41.3% (n = 45/109) patients exhibiting IL-6 ≥14 pg/ml. From BL to M3, IL-6 decreased in 63.8% (n = 37/58; Vienna cohort) and in 68.6% (n = 35/51; Hannover cohort) of patients, respectively. Similar rates of decreases were observed also for CRP (in 62.1%) and for LBP (in 77.4%). A considerable IL-6 reduction (≥50% of baseline) was noted in 41 (37.6%) patients during follow-up. Competing risk regression in the combined cohort adjusted for age, albumin, and model for end-stage liver disease revealed that IL-6 decrease at M3 was an independently protective factor for the development of ACLF (adjusted subdistribution hazard ratio [asHR]: 0.26; 95% CI: 0.09-0.77; p = 0.016) and liver-related death (asHR: 0.26; 95% CI: 0.07-0.95; p = 0.042).

Conclusions

TIPS leads to a sustained reduction of SI and bacterial translocation in patients with decompensated cirrhosis. Decreasing IL-6 levels three months after TIPS implantation indicate a lower risk of ACLF and liver-related death in patients with cirrhosis.

Impact and implications

Systemic inflammation is a major driver of disease progression in patients with decompensated advanced chronic liver disease (dACLD). This study demonstrates that systemic inflammation (i.e. interleukin-6 [IL-6]) effectively and sustainedly decreases after transjugular intrahepatic portosystemic shunt (TIPS) implantation. A decrease of IL-6 3 months after TIPS implantation is a protective factor for acute-on-chronic liver failure and liver-related death. Thus, our results suggest that TIPS reduces systemic inflammation in a clinically meaningful way.

Hepatocellular carcinoma: Revising the surgical approach in light of the concept of multiparametric therapeutic hierarchy

The clinical management of hepatocellular carcinoma (HCC) is strongly influenced by several prognostic factors, mainly tumor stage, patient's health, liver function and specific characteristics of each intervention. The interplay between these factors should be carefully evaluated by a multidisciplinary tumor board. To support this, the novel "multiparametric therapeutic hierarchy" (MTH) concept has been recently proposed. This review will present the main features of available surgical treatments for HCC (liver transplantation, liver resection, ablation). Strengths and weaknesses are reported in the light of clinical decision making and of treatment allocation, with a special focus on the collocation of each treatment in the MTH framework and on how MTH may be useful in supporting clinical decision. Sequential treatments and their role to allow further surgical treatments will also be analyzed.

Screening and management of portal hypertension and varices in cirrhosis: Expert perspectives

The prevalence of liver injury, fibrosis, and, in particular, cirrhosis in the United States is increasing in parallel to the current epidemic of metabolic dysfunction-associated steatotic liver disease and alcohol-associated liver disease. As fibrosis advances, portal hypertension occurs, and when the pressure gradient meets or exceeds 10 mm Hg, the patient is at an increased risk for decompensating events such as esophageal varices. The risk of death also increases. Therefore, decreasing the risk of progression to decompensated cirrhosis is an important management goal. The American Association for the Study of Liver Diseases recently published a guidance document to "coalesce best practice recommendations for the identification of portal hypertension, for prevention of initial hepatic decompensation, for the management of acute variceal hemorrhage, and for reduction of the risk of recurrent variceal hemorrhage in chronic liver disease." In this updated guidance, the new terms "advanced chronic liver disease" and "clinically significant portal hypertension" have been proposed for routine use in clinical practice. Following recommendations for advanced chronic liver disease identification, which are largely defined by transient elastography measurements of liver stiffness, guidance is provided on the identification of clinically significant portal hypertension and early administration of nonselective beta-blocker therapy in clinically significant portal hypertension for prophylaxis. Optimal control of active bleeding, the role of preemptive TIPS, and gastric varices management are also addressed. Despite the wealth of information provided, the guidance can be difficult to put into practice, leaving non-liver-focused clinicians with an unmet need for a simplified approach to guidelines in general. To address this issue, a panel of hepatologists met to review and discuss the real-world implications of this new guidance and the result is this expert perspective review. This review aims to facilitate improvements in risk stratification and management of variceal bleeding, streamline controversial and complex issues in the recent guidance in a practical way for clinical use, and make recommendations on how to incorporate this important new guidance document into clinical practice.

Fine-Needle Portosystemic Pressure Gradient as a Reference for Portal Hypertension in Patients with Intrahepatic Venovenous Shunt: A Prospective Study

PURPOSE

To evaluate the consistency and agreement between portal venous pressure measured by a fine needle (FN-PVP), direct portal vein catheterization (D-PVP), and wedged hepatic vein balloon occlusion (W-HVP) in patients with decompensated cirrhosis and intrahepatic venovenous shunts (IHVSs).

MATERIALS AND METHODS

One hundred fifty-six consecutive patients planning to receive a transjugular intrahepatic portosystemic shunt in the authors' center were screened for study participation. The FN-PVP, D-PVP, and W-HVP were assessed for consistency by Pearson coefficient (r), linear regression coefficient (R2), and intraclass correlation coefficient (ICC) and for disagreement (error exceeding 20% of D-PVP) by the Bland-Altman method.

RESULTS

Of 92 eligible patients, FN-PVP was successfully obtained in 37 (40.2%) with IHVS, with no puncture-related adverse events. In these patients, there were significant differences between W-HVP and D-PVP (-14.3 mm Hg; P < .001) with poor consistency (r = 0.410; R2 = 0.168; ICC, 0.105) but only minor differences between FN-PVP and D-PVP (-0.5 mm Hg; P = .134) with good consistency (r = 0.951; R2 = 0.904; ICC, 0.944). This pattern did not change when pressure gradients were compared (R2 = 0.083/0.767) and adjusted by stiffness measurements and platelet counts (R2 = 0.196/0.789). The W-HVP/D-PVP and FN-PVP/D-PVP disagreement occurred in 47.8% (34 with IHVS, 91.9%) and 0.0% of patients, respectively. In multivariate linear regression, only the presence of portal vein thrombosis (P = .045) was an independent predictor for the lower FN-PVP/D-PVP ratio. Portosystemic pressure gradient of FN-PVP showed greater ability to stratify that of D-PVP of 16 mm Hg (area under the curve, 1.000 vs 0.574; P < .001) and 20 mm Hg (0.974 vs 0.662; P = .001) than that of W-HVP.

CONCLUSIONS

FN-PVP measurement may be a valid and safe approach to reflect the severity of sinusoidal portal hypertension in patients with IHVS.

Predictors of long-term clinical outcomes after TIPS: An ALTA group study

BACKGROUND AND AIMS

While TIPS is traditionally considered a bridge to liver transplant (LT), some patients achieve long-term transplant-free survival (TFS) with TIPS alone. Prognosis and need for LT should not only be assessed at time of procedure, but also re-evaluated in patients with favorable early outcomes.

APPROACH AND RESULTS

Adult recipients of TIPS in the multicenter advancing liver therapeutic approaches retrospective cohort study were included (N=1127 patients; 2040 person-years follow-up). Adjusted competing risk regressions were used to assess factors associated with long-term post-TIPS clinical outcomes at the time of procedure and 6 months post-TIPS. MELD-Na at TIPS was significantly associated with post-TIPS mortality (subdistribution hazards ratio of death 1.1 [ p =0.42], 1.3 [ p =0.04], and 1.7 [ p <0.01] for MELD-Na 15-19, 20-24, and ≥25 relative to MELD-Na <15, respectively). MELD 3.0 was also associated with post-TIPS outcomes. Among the 694 (62%) patients who achieved early (6 mo) post-TIPS TFS, rates of long-term TFS were 88% at 1 year and 57% at 3 years post-TIPS. Additionally, a within-individual increase in MELD-Na score of >3 points from TIPS to 6 months post-TIPS was significantly associated with long-term mortality, regardless of initial MELD-Na score (subdistribution hazards ratio of death 1.8, p <0.01). For patients with long-term post-TIPS TFS, rates of complications of the TIPS or portal hypertension were low.

CONCLUSIONS

Among patients with early post-TIPS TFS, prognosis and need for LT should be reassessed, informed by postprocedure changes in MELD-Na and clinical status. For selected patients, "destination TIPS" without LT may offer long-term survival with freedom from portal hypertensive complications.

The Role of Endoscopic Ultrasound in Assessing Portal Hypertension: A State-of-the-Art Literature Review and Evolving Perspectives

BACKGROUND

Portal hypertension (PH) is a critical complication in patients with hepatic diseases. Its accurate evaluation is essential for early diagnosis, risk stratification, and management. Endoscopic ultrasound (EUS) has emerged as a promising diagnostic tool, offering high-resolution imaging of the portal venous system, hepatic vasculature, and surrounding structures.

AIMS

This review aims at providing an overview of the evolving role of EUS in PH evaluation in patients with liver disease.

MATERIALS AND METHODS

A systematic search was conducted in PubMed and Google Scholar until 31 May 2024. Relevant studies were identified using keywords related to EUS and PH. Additional references were included based on expert knowledge and citation analysis. Only full-length papers and abstracts in English were considered.

RESULTS

EUS demonstrates significant utility in PH assessment, offering high-resolution imaging and advanced tools like contrast enhancement (CE) and shear-wave elastography (SWE) for evaluating liver stiffness and correlating it with PH severity. EUS-guided portal pressure gradient (PPG) measurement provides a less invasive method for evaluating PH, potentially offering a safer alternative to conventional techniques.

DISCUSSION

EUS offers unique advantages in PH assessment, enabling comprehensive evaluation in a single session. Despite its potential, limitations such as invasiveness, sedation-related variability, and restricted availability persist. Emerging techniques require further validation in larger cohorts and standardised training.

CONCLUSION

EUS is a valuable diagnostic tool for PH evaluation, with the potential to improve outcomes through earlier diagnosis and better stratification. Addressing its limitations through further research and standardised protocols is critical to optimize its clinical utility.

Inflammation remains a dynamic component of portal hypertension in regressive alcohol-related cirrhosis

BACKGROUND

Portal hypertension (PH) resulting from static and dynamic intrahepatic changes drives liver-related complications even after removing the underlying aetiological factor.

OBJECTIVE

We investigated the impact of inflammation on the dynamic component of PH during disease regression in animal models of toxin-induced cirrhosis and patients with alcohol-related cirrhosis.

METHODS

In mice, cirrhosis was induced via toxin application for 12 weeks followed by toxin-withdrawal allowing for one or 2 weeks of regression. Furthermore, 128 patients with alcohol-related cirrhosis and alcohol abstinence undergoing same-day hepatic venous pressure gradient (HVPG) and liver stiffness measurement (LSM) were included. The influence of inflammation on the dynamic PH component was assessed using linear models. Specifically, we explored proinflammatory changes in mice/patients in whom the measured portal pressure (PP)/HVPG was significantly higher than the PP/HVPG expected from the static PH component (histological collagen proportionate area [CPA; %] in mice, LSM in patients).

RESULTS

In mice, toxin discontinuation induced a significant decrease in PP, CPA, histological hepatic inflammation and hepatic expression of proinflammatory genes (Tnfa, Il6, Cxcl1, Mcp1; all p < 0.05 for one/2 week regression vs. peak disease). Similarly, prolonged abstinence in alcohol-related cirrhosis was linked to lower HVPG/LSM and longer abstinence was correlated to lower C-reactive protein (CRP), IL-6, immunoglobulin A (IgA) and IgG levels (all p < 0.05). Nevertheless, the persistence of a low-grade proinflammatory state during regression was linked to a higher PP/HVPG than expected from static PH components. In regressive mice, higher hepatic proinflammatory gene expression (Tnfa, Il6, Il1b; all p < 0.05) was linked to higher-than-expected PP. Similarly, higher CRP, IL-6, IgA and IgG and lower complement factor C3c (all p < 0.05) were associated with higher-than-expected HVPG in abstinent patients with alcohol-related cirrhosis.

CONCLUSIONS

Although removing the underlying aetiological factor resulted in significant improvements, a persistent hepatic proinflammatory environment remained a key driver of the dynamic PH component in regressive liver disease.

Early Dynamics of Portal Pressure Gradient After TIPS Insertion Predict Mortality

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) placement leads to a reduction in portal pressure and an improvement in survival in patients with recurrent and refractory ascites and variceal haemorrhage. Prediction of post-TIPS survival is primarily determined by factors identified before the TIPS procedure, as data collected during or after TIPS implantation are limited. The aim of the study was to evaluate the influence of early hemodynamic changes after TIPS placement on survival, in order to refine post TIPS management.

METHODS

In this prospective bicentric study, consecutive patients (n = 105) undergoing TIPS placement for ascites or variceal haemorrhage underwent measurement of portal pressure gradient (PPG) immediately at TIPS insertion (PPG0) and 24 h later (PPG24h) and the ΔPPG was calculated from PPG24h and PPG0 (ΔPPG = PPG24h-PPG0). Kaplan-Meier survival analysis and uni- and multivariable regression analyses were conducted to identify survival predictors.

RESULTS

Patients with lack of increased ΔPPG exhibited poorer 90-day and 1-year survival compared to patients with increased ΔPPG. This worse survival was independent of The Model for End-Stage Liver Disease (MELD) score, Child-Pugh score, bilirubin levels, creatinine and the Freiburg index of post-TIPS survival (FIPS) > 0.92. Among these patients with poorer outcome, elevated bilirubin (> 25 μmol/L) further distinguished survivors from non-survivors.

CONCLUSION

Lack of increased ΔPPG post-TIPS insertion identifies a high-risk patient group with worse survival. We propose incorporating this second PPG measurement and determining ΔPPG into clinical practice to identify these patients early and tailor post-TIPS patient care.

Post-TIPS Overt Hepatic Encephalopathy Increases Long-Term but Not Short-Term Mortality in Cirrhotic Patients With Variceal Bleeding: A Large-Scale, Multicenter Real-World Study

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) is an established procedure for managing portal hypertension in cirrhotic patients, but the impact of post-TIPS overt hepatic encephalopathy (OHE) on survival remains controversial. While its effect on short-term survival is well-documented, its long-term implications remain unclear.

AIMS

This study aims to investigate the long-term impact of post-TIPS OHE on mortality in cirrhotic patients for variceal bleeding, focusing on the timing and predictive value of OHE beyond the first year post-TIPS.

METHODS

A multicenter, retrospective cohort study was conducted involving 3262 cirrhotic patients who underwent TIPS for variceal bleeding at seven Chinese tertiary centers between January 2010 and June 2020. Clinical data, including demographics, procedure details, post-TIPS complications and survival outcomes, were collected. The primary endpoints were all-cause mortality and OHE, with follow-up until death, liver transplantation or 60 months. Propensity score matching minimised confounding effects, and multivariate Fine-Grey competing risk models identified independent mortality predictors.

RESULTS

During a median follow-up of 1077 days, 33.2% developed post-TIPS OHE, associated with higher MELD and Child-Pugh scores. Among these, 19.3% died, with a median time from OHE onset to death of 947 days. Post-TIPS OHE was not linked to early survival (within 12 months) but emerged as an independent predictor of long-term mortality beyond 24 months, consistent across various clinical scenarios.

CONCLUSION

Post-TIPS OHE does not affect short-term survival but significantly increases long-term mortality risk. These findings highlight the need for continuous monitoring and tailored interventions to improve long-term outcomes in post-TIPS patients.

Development of Liver-Heart Score for Early Detection of Myocardial Contractile Dysfunction in Cirrhosis by Strain Imaging

AIM

Cirrhotic cardiomyopathy is characterised by myocardial dysfunction in patients with cirrhosis in the absence of other cardiac conditions. We aimed to develop and validate a scoring system to identify patients at high risk for reduced global longitudinal strain, a newly proposed marker of myocardial dysfunction in the updated diagnostic criteria for cirrhotic cardiomyopathy.

METHODS

Prospectively recruited patients with cirrhosis in the training and validation groups underwent identical hepatological and cardiological evaluations, including strain echocardiography. Risk factors for myocardial dysfunction were identified using logistic regression.

RESULTS

In a cohort of 452 consecutive patients, 278 were excluded due to non-cirrhotic cardiomyopathy or conditions potentially affecting strain measurements. The prevalence of reduced global longitudinal strain was 9.8% (13/133) in the training group and 19.5% (8/41) in the validation group. Multivariate logistic regression revealed BMI ≥ 28 kg/m2 (OR 7.02), CAP > 260 dB/m (OR 8.53), and age > 57 years (OR 4.68) as independent predictors of reduced myocardial contractility. These variables were combined and weighted based on their beta coefficients to develop the Liver-heart score (CAP > 260 dB/m [2 pts], BMI ≥ 28 kg/m2 [2 pts], age > 57 years [1 pt]). The AUC-ROC was 0.84 in the training and 0.83 in the validation cohort. A Liver-heart score of 5 points was associated with increased mortality, observed at 2 years (44.4% vs. 17.3%) and the end of the follow-up period (66.7% vs. 37.7%, HR 1.3, p < 0.01).

CONCLUSION

The Liver-heart score can accurately rule out reduced myocardial contractility and may be useful for risk stratification in cirrhotic patients.

Integrating prior decompensation into ACLF definition to enhance clinical management

BACKGROUND

Acute-on-chronic liver failure (ACLF) is a complicated syndrome associated with high short-term mortality and reversibility. Whether the prior decompensation should be included in the definition of ACLF is controversial.

METHODS

A total of 532 patients with decompensation (prior or first) of chronic liver disease were retrospectively enrolled and analyzed from January 2018 to June 2023. Clinical data were used to identify the characteristics and determine prognosis.

RESULTS

Of the 532 patients, 99 patients did not meet APASL-ACLF criteria due to the existence of prior decompensation and 433 patients met the Asian Pacific Association for the Study of the Liver (APASL)-ACLF criteria. The two groups had similar characteristics including prognosis scores (Chinese Group on the Study of Severe Hepatitis B (COSSH)-ACLF II score: 7.59 vs. 7.67, p = 0.934; Chronic Liver Failure (CLIF) Consortium ACLF score: 42.90 vs. 44.81, p = 0.273), the distribution of patients with APASL ACLF research consortium score (AARC score) (5-7: 19.2%/12.0%; 8-10: 56.6%/55.0%; 11-15: 24.2%/33.0%, p > 0.05) and the 28-/90-day mortality rates (30.5%/43.2% vs. 36.3%/43.1%, p = 0.267/0.978). In all integrated ACLF patients, Receiver Operating Characteristic (ROC) curve analysis and decision curve analysis (DCA) showed that COSSH-ACLF IIs had higher prognostic efficiency and clinical net benefit than AARC score and CLIF-C ACLFs for 28-/90-day mortality.

CONCLUSION

Prior decompensated patients exhibited clinical characteristics and high short-term mortality similar to those of first decompensated patients. The COSSH-ACLF IIs demonstrated the highest prognostic efficiency for all integrated ACLF patients. Including prior decompensation in the ACLF definition can help to simplify and improve clinical management.

Risk Factors for Glue Extrusion Bleeding After Endoscopic Injection of Cyanoacrylate Glue for Gastric Varices: A Retrospective Study of 269 Patients

BACKGROUND

Glue extrusion bleeding is a major complication of endoscopic cyanoacrylate glue injection for the treatment of gastric varices. However, its risk factors remain unclear.

AIMS

This retrospective study aimed to evaluate the risk factors for bleeding associated with glue extrusion.

METHODS

This study analyzed the medical data of cirrhotic patients who underwent endoscopic obliteration for gastric varices using cyanoacrylate glue between January 2016 and December 2022. The data within 1 year after therapy were carried out with logistic regression. A nomogram model was constructed based on the factors.

RESULTS

269 patients were enrolled. Risk factors associated with glue extrusion bleeding included the volume of the glue (≥ 4 mL)(OR 1.289, 95% CI 1.051-1.580; P = 0.015), massive ascites (OR 5.645, 95% CI 2.260-14.097; P = 0.000), active hemorrhage during endoscopy (OR 2.830, 95% CI 1.284-6.234; P = 0.010), and the use of β-blockers was a protective factor (OR 0.185, 95% CI 0.07-0.485; P = 0.001). The nomogram model had good prediction accuracy, with an area under the curve of 0.74 (95% CI 0.658-0.822; P < 0.001).

CONCLUSION

Massive ascites, active hemorrhage during endoscopy, glue volume ≥ 4 mL, and the use of β-blockers are associated with glue extrusion bleeding. At-risk patients may benefit from controlling the volume of the glue, undergoing endoscopic ultrasound and using β-blockers.

Future of Endoscopy in Surveillance of Esophageal Varices

PURPOSE OF REVIEW

tTo assess the evolving role of endoscopy assessment for esophageal varices in cirrhosis.

RECENT FINDINGS

The approach to screening endoscopy for varices has significantly changed in the last 10 years with the refinement of non-diagnostic tests. Non-invasive diagnostic methods have reduced the need of upper endoscopies for variceal screening in patients with compensated cirrhosis, focusing primarily on those with ambiguous risk assessments or contraindications to non-selective beta-blockers (NSBBs). In contrast, decompensated cirrhosis patients require more frequent endoscopic evaluations due to their heightened risk of complications and the potential benefit of combination therapy (NSBBs + variceal ligation). In patients with hepatocellular carcinoma (HCC) the performance of non-invasive tests is suboptimal and most patients require endoscopy. Emerging applications of artificial intelligence (AI) can assist in patient triage and the interpretation of endoscopic findings, potentially improving care. Further research is essential to validate these technologies within clinical practice and optimize their integration into patient management strategies.

Chinese Guidelines on the Management of Hepatic Encephalopathy in Cirrhosis (2024)

With progress in basic and clinical research on hepatic encephalopathy in cirrhosis worldwide, the Chinese Society of Hepatology of the Chinese Medical Association has invited experts in relevant fields to revise the 2018 "Chinese Guidelines on the Management of Hepatic Encephalopathy in Cirrhosis." The updated guidelines provide recommendations for the clinical diagnosis, treatment, and both primary and secondary prevention of hepatic encephalopathy in cirrhosis.

Effect of portal pressure gradient reduction on outcomes after transjugular intrahepatic portosystemic shunt in portal hypertension patients

BACKGROUND

Portal hypertension (PHT), a complication of liver cirrhosis, is sometimes managed with transjugular intrahepatic portosystemic shunt (TIPS) to reduce portal pressure. Although effective, TIPS poses risks, including hepatic encephalopathy (HE). This study investigates whether a significant reduction in the portal pressure gradient (PPG) after TIPS improves outcomes in PHT patients.

AIM

To evaluate the impact of post-TIPS PPG reduction on clinical outcomes and explore the relationship between PPG reduction and portal vein diameter.

METHODS

This retrospective cohort study included 815 patients with PHT who underwent TIPS at two tertiary hospitals between 2014 and 2022. Patients were categorized based on whether they achieved a 50% reduction in PPG. Propensity score matching was applied to balance baseline characteristics. Kaplan-Meier analysis assessed clinical outcomes, including rebleeding, HE, liver failure, and hepatocellular carcinoma. Cox regression identified risk factors, and Spearman correlation analyzed the relationship between PPG reduction and portal vein diameter.

RESULTS

Patients with a PPG reduction > 50% had significantly lower risks of rebleeding (P = 0.004), shunt dysfunction (P = 0.002), and mortality (P = 0.024) compared to those with a PPG reduction ≤ 50%. However, these patients faced higher risks of HE (P < 0.001) and liver failure (P = 0.003). A significant negative correlation was observed between the percentage of PPG reduction and portal vein diameter (ρ = -0.632, P < 0.001), suggesting that patients with smaller portal vein diameters may achieve greater PPG reductions.

CONCLUSION

A significant PPG reduction following TIPS is associated with improved clinical outcomes, including reduced risks of rebleeding, shunt dysfunction, hepatocellular carcinoma, and mortality, though it increases HE and liver failure risks. The observed correlation between portal vein diameter and PPG reduction highlights the potential role of portal vein anatomy in predicting TIPS efficacy, warranting further investigation.

Relationship between coagulopathy score and survival in critically ill patients with liver cirrhosis and sepsis: a retrospective study

BACKGROUND

This research focused on exploring the association between coagulopathy scores and the survival outcomes, both short-term and long-term, in individuals diagnosed with liver cirrhosis complicated by sepsis.

METHODS

This study retrospectively analyzed data from individuals with liver cirrhosis and sepsis who were admitted to the intensive care unit (ICU) at Beth Israel Deaconess Medical Center between 2008 and 2022. The main outcome of interest was all-cause mortality within 28 days post-admission, while the secondary outcome assessed mortality within 90 days. We used the Kaplan-Meier analysis to compare the mortality risk among the different groups. To evaluate the relationship between coagulopathy score and mortality risk in patients with liver cirrhosis and sepsis, a multivariate Cox proportional hazards regression analysis was performed. The predictive performance of the coagulopathy score for short- and long-term all-cause mortality was assessed using receiver operating characteristic (ROC) curve analysis, which included evaluation of its sensitivity, specificity, and area under the curve. Subgroup analyses were performed to evaluate the relationship between coagulopathy score and survival across different groups.

RESULTS

The study included a total of 2,278 patients. Kaplan-Meier survival analysis demonstrated that individuals with elevated coagulopathy scores exhibited markedly higher rates of ICU mortality, in-hospital mortality, as well as 28-day and 90-day mortality, with all log-rank tests yielding P-values of less than 0.001. The results of the multivariate Cox regression analysis showed that an elevated coagulopathy score was independently linked to higher 28-day and 90-day all-cause mortality, both before and after controlling for potential confounders. ROC curve analysis showed that although the coagulopathy score was slightly less predictive of prognosis than the Model for End-stage Liver Disease score, it significantly outperformed the Sequential Organ Failure Assessment score and the Sepsis-induced Coagulopathy score. Subgroup analysis revealed no significant interaction between the coagulopathy score and survival across the different subgroups.

CONCLUSIONS

Higher coagulopathy scores in critically ill patients with liver cirrhosis and sepsis were independently associated with poor prognosis. Due to its simplicity and potential predictive value, the coagulopathy score can serve as an effective complement to existing clinical tools for managing critically ill patients with liver cirrhosis and sepsis.

[Cardiometabolic and genetic factors in the progression of metabolic dysfunction-associated steatotic liver disease]

AIM

To evaluate the contribution of cardiometabolicfactors and PNPLA3 I148M (rs738409 C>G) gene polymorphism to the development of compensated advanced chronic liver disease (cACLD) in patients with metabolic dysfunction-associated steatotic liver disease (MASLD).

MATERIALS AND METHODS

108 patients with MASLD were enrolled and formed the internal validation group; 30 patients with MASLD were selected for external validation. Anamnestic data, anthropometric and laboratory parameters and the presence of PNPLA3 gene polymorphism I148M (rs738409 C>G) were assessed. Steatosis was detected by assessing the controlled attenuation parameter. Liver elasticity was assessed by transient elastography. cACLD was detected when the liver stiffness was ≥8 kPa.

RESULTS

Statistically significant difference was observed in the internal validation group during comparison of the incidence of cACLD depending on the presence of arterial hypertension (odds ratio - OR 5.58; 95% confidence interval - CI 1.21-25.71), type 2 diabetes mellitus - T2DM (OR 4.58; 95% CI 1.59-13.21), obesity (OR 3.13; 95% CI 1.1-8.9), dyslipidemia (OR 6.12; 95% CI 1.33-28.19) and the mutant G allele of the PNPLA3 gene (OR 3.9; 95% CI 1.28-11.88). Patients with cACLD had significantly higher mean values of waist circumference (WC), alanine aminotransaminase, aspartate aminotransaminase, gamma-glutamyl transferase and triglycerides, non-invasive markers of steatosis and fibrosis. The compiled prognostic model demonstrated a direct relationship between the likelihood of developing cACLD and the presence of T2DM (adjusted odds ratio - AOR 3.28; 95% CI 0.62-17.33), dyslipidemia (AOR 5.89; 95% CI 1.21-28.67) and WC value (AOR 1.05; 95% CI 1.01-1.11). PNPLA3 I148M gene polymorphism did not significantly affect the development of late stages of the disease. External validation of the model showed its moderate diagnostic ability.

CONCLUSION

T2DM, dyslipidemia and WC values are the determining factors in the development of cACLD in patients with MASLD. The PNPLA3 I148M gene polymorphism has no leading importance for the development of the progressive course of MASLD in the studied cohort.

Benefits of TIPS for Patients With Large Ascites Preceding Recurrent or Refractory ascites: A Multicenter Cohort Study

BACKGROUND AND AIM

Patients with recurrent or refractory ascites can benefit from transjugular intrahepatic portosystemic shunt (TIPS). However, the value of TIPS for patients with large ascites remains unclear.

METHODS

This retrospective multicenter study included patients who underwent TIPS or medicine plus large-volume paracentesis (medicine + LVP) for ascites between January 2014 and December 2022 at five centers. The primary endpoint was recurrence or worsening of ascites. The secondary endpoints were liver-related death, all-cause hemorrhage, overt hepatic encephalopathy (OHE), and shunt dysfunction.

RESULTS

Overall, 724 patients were evaluated, including 373 patients with large ascites preceding recurrent or refractory ascites received TIPS (the LA-TIPS group), 282 patients with recurrent and refractory ascites received TIPS (the RA-TIPS group), and 69 patients with large ascites preceding recurrent or refractory ascites received medicine + LVP (the LA-M group). Patients in the LA-TIPS group had significantly lower incidences of recurrence or worsening of ascites (37.4% vs. 45.3%, p < 0.001), liver-related death (44.8% vs. 62.0%, p < 0.001), and OHE (47.3% vs. 60.3%, p < 0.001) than those in the RA-TIPS group. Meanwhile, patients in the LA-TIPS group had significantly lower incidences of recurrence or worsening of ascites (37.4% vs. 44.6%, p = 0.006) and hemorrhage (38.3% vs. 47.2%, p = 0.042), but a higher incidence of OHE (34.2% vs. 4.5%, p < 0.001) than those in the LA-M group.

CONCLUSIONS

In terms of controlling ascites, the benefit of TIPS was greater in patients with large ascites preceding recurrent or refractory ascites, suggesting that TIPS might be considered in patients with large ascites before they progress to recurrent or refractory stages.

Study protocol to redefine muscle attenuation cut-offs for better prediction of mortality in patients with cirrhosis: a comprehensive post hoc validation study - a study protocol

INTRODUCTION

Myosteatosis, characterised by altered muscle composition detectable by muscle radiodensity attenuation on CT scans, has been associated with increased mortality in patients with cirrhosis. However, standard attenuation cut-offs, derived primarily from oncology populations, may not be appropriate for patients with cirrhosis. This study protocol aims to address this diagnostic gap by validating the Ebadi cut-offs, which are based on a retrospective cohort and have not been extensively validated in a cirrhotic population. The aim of the study is to refine these cut-offs for more accurate prediction of mortality in patients with cirrhosis using two independent patient cohorts (retrospective and prospective).

METHODS AND ANALYSIS

This post hoc validation study analyses muscle weakness cut-offs in patients with cirrhosis using data from two independent cohorts. A total of 1537 patients will be analysed. The study will assess interobserver variability to ensure robust results by analysing random samples of 60 patients from the two cohorts. Statistical methods will be used to determine the accuracy and relevance of current cut-offs in predicting patient mortality. The analysis will also examine the relationship between muscle wasting and clinical outcomes in cirrhosis and the relationship with muscle mass loss.

ETHICS AND DISSEMINATION

Ethical approval for this study has been obtained from the relevant institutional review boards. The results will be disseminated through presentations at scientific conferences and publication in peer-reviewed journals. The results of the study are expected to contribute to improved diagnostic criteria for myosteatosis in cirrhosis, providing clinicians with more tailored and accurate tools for cirrhosis prognosis.

Anticoagulation for splanchnic vein thrombosis in acute pancreatitis increases bleeding risk without improving outcomes

BACKGROUND/OBJECTIVES

Treatment guidelines on anticoagulation (AC) to treat splanchnic vein thrombosis (SVT) after acute pancreatitis (AP) are not well-established. This research examines the efficacy and safety of AC in SVT.

METHODS

We retrospectively investigated the demographics, clinical progression, radiologic findings, interventions, and outcomes of patients with AP between 2018 and 2022 at a single tertiary care center. The primary and secondary outcomes were development of SVT in AP and effects of AC, respectively.

RESULTS

897 patients developed AP (average 50.5 years old, 46% female, 20% moderately severe AP, 4% severe AP), of whom 4.8% developed SVT. SVT was associated with recurrent and chronic pancreatitis (28%, p = 0.021 and 37%, p < 0.001) and malignancy (21%, p < 0.001). SVT was associated with severe pancreatitis courses (12% vs. 3%, p < 0.001) and an increase in six-month mortality (14% vs. 4%, p = 0.022). AC was used for 47% of patients with SVT. However, AC did not prevent SVT sequelae, including gastroesophageal varices formation (p = 1), variceal hemorrhage (p = 0.68), or splenic infarction (p = 1), and did not improve survival (p = 0.19). While AC did not improve outcomes, it was associated with bleeding episodes in 50% of patients (p < 0.001).

CONCLUSIONS

Approximately half of patients who develop SVT after AP receive AC despite no reduction in adverse events or mortality. Additionally, half of patients receiving AC experience bleeding complications. The limited evidence presented in this study suggests that the risks of AC for SVT in AP may outweigh its benefits and highlights the need for future studies in larger prospective cohorts.

Carbohydrate Quality Is Independently Associated with Cardiometabolic Risk in Chinese Individuals with Impaired Glucose Tolerance

Background/Objectives: Dietary manipulation with carbohydrate restriction has been extensively investigated in diabetes prevention programmes. Carbohydrate (CHO) quality, rather than quantity, is associated with various metabolic outcomes. Few studies examined the fibre/CHO ratio on lipid profiles, liver fat and insulin resistance in individuals with impaired glucose tolerance (IGT). Methods: In this comprehensive cross-sectional study, we evaluated the association of carbohydrate-related nutritional factors with metabolic parameters in a cohort of 177 Hong Kong Chinese with impaired glucose tolerance (IGT). The subjects underwent a 75 g oral glucose tolerance test (OGTT) with measurement of plasma C-peptide and lipid profiles, body composition, transient elastography, and three-day food records. The fibre/CHO ratio is calculated by dividing fibre intake by total carbohydrate intake (in grams). Results: The median (IQR) age of the study cohort was 60 (54-62) with a mean ± SD BMI of 26.7 ± 3.9 kg/m2, and 40.7% were female. A higher carbohydrate quality, measured as fibre/CHO ratio, was inversely correlated with triglycerides (r = -0.305, p < 0.001) and positively correlated with High-density lipoproteins cholesterol (HDL-C) (r = 0.354, p < 0.001). These associations remained significant after adjusting for age, gender, lipid-lowering drugs, total calorie, macronutrient and sugar intake, physical activity and sodium/potassium ratio. Blood pressure, liver fat and insulin resistance were also associated with the fibre/CHO ratio after the adjustment of these confounding factors. Consuming more than 5.5 g of fibre per 100 g carbohydrate was associated with lower serum triglycerides. Conclusions: Our results highlight the potential for using the fibre/CHO ratio as a metric for daily carbohydrate quality and the importance of addressing both carbohydrate quality and quantity in designing dietary interventions to reduce cardiometabolic risk.

Role of transient elastography in the diagnosis and prognosis of Fontan-associated liver disease

BACKGROUND

Fontan-associated liver disease (FALD) often occurs in patients with single-ventricle physiology following Fontan surgery, and ranges from liver congestion to cirrhosis. The assessment of the severity of FALD using noninvasive methods is challenging. However, transient elastography (TE) may be useful for the noninvasive evaluation of FALD and prediction of clinical outcomes.

AIM

To evaluate the role of TE in the diagnosis of FALD and its association with clinically relevant events.

METHODS

This retrospective single-center study (Hospital Universitario La Paz, Madrid), including 91 post-Fontan patients aged > 18 years old. Laboratory and ultrasound findings, and liver stiffness measurements (LSM) by TE (FibroScan®) were assessed. FALD was defined using ultrasound criteria (hepatomegaly, liver surface nodularity, parenchymal heterogeneity, hyperechoic lesions, splenomegaly, collaterals) and advanced FALD was defined according to the European Association for the Study of the Liver-European Reference Network statement (esophageal varices, portosystemic shunts, ascites, splenomegaly). Clinically relevant events included heart or heart-liver transplantation indication, hepatocellular carcinoma, and all-cause mortality.

RESULTS

Patient characteristics were: 60.4% male; Mean age, 33.3 ± 8.2 years; Mean elapsed time since surgery, 24.3 ± 7.7 years; 89% with FALD; 73% with advanced FALD. LSM by TE was associated with FALD [odds ratio (OR) = 1.34; 95% confidence interval (95%CI): 1.10-1.64; P = 0.003] and advanced FALD (OR = 1.10; 95%CI: 1.01-1.19; P = 0.023). Areas under the curve (AUC) were 0.905 and 0.764 for FALD and advanced FALD, respectively. FALD cut-off values comprised: Optimal, 20 kPa (sensitivity: 92.3%; specificity: 80.0%); Rule-out, 15 kPa (sensitivity: 96.9%); Rule-in, 25 kPa (specificity: 100%). A FALD algorithm was proposed based on LSM by TE and elapsed time since surgery (AUC: 0.877; sensitivity, 95.4%; specificity, 80.0%; positive predictive value, 96.9%; negative predictive value, 72.7%). LSM by TE was associated with clinically relevant events (OR = 1.07; 95%CI: 1.01-1.13; P = 0.021) and all-cause mortality (OR = 1.23; 95%CI: 1.02-1.47; P = 0.026).

CONCLUSION

In adult patients post-Fontan surgery, TE is a useful noninvasive method for FALD diagnosis. The association between LSM by TE and clinically relevant events suggests a role in prognosis.

From "Burnt-Out" to "Burning-Out": Capturing Liver Fat Loss in Patients With Advanced Metabolic Dysfunction-Associated Steatotic Liver Disease From a Dynamic Perspective

BACKGROUND AND AIMS

The absence of hepatic fat in advanced fibrosis has been documented in metabolic dysfunction-associated steatotic liver disease (''burnt-out" MASLD). However, whether hepatic fat loss occurs continuously with fibrosis progression is controversial. We proposed a "burning-out" concept to describe this process and analyze the long-term outcomes of "burnt-out" and "burning-out" MASLD.

METHODS

We included a MASLD cohort from 16 centers, including 3273 individuals with baseline histology and 5455 with serial vibration-controlled transient elastography measurements during the follow-up. "Burnt-out" MASLD was defined by steatosis grade ≤S1 and fibrosis stage ≥F3. Trajectory analysis identified "burning-out" patients with continuous trends of decreasing controlled attenuation parameter and increasing liver stiffness measurement values.

RESULTS

Of 3273 patients with histologic evaluation included, 435 had "burnt-out" MASLD. Compared with those with pronounced steatosis in advanced fibrosis, patients with "burnt-out" had higher risks of all-cause mortality (hazard ratio [HR], 2.14; 95% confidence interval [CI], 1.14-4.02), liver-related events (LREs; HR, 1.77; 95% CI, 1.12-2.78), and hepatic decompensation (HR, 1.83; 95% CI, 1.11-3.01). Of 5455 patients with vibration-controlled transient elastography included for trajectory analysis, 176 were identified as "burning-out" MASLD. The incidence rates of all-cause mortality, LREs, and decompensation were 7.28, 26.47, and 21.92 per 1000 person-years in "burning-out" patients, respectively. The "burning-out" group had higher cumulative incidences of adverse outcomes than patients with consistently high controlled attenuation parameter and moderate/low liver stiffness measurement values (P < .0001).

CONCLUSIONS

Continuous hepatic fat loss accompanied by fibrosis progression, referred to as "burning-out," was observed in advanced MASLD and associated with high rates of all-cause mortality, LREs, and hepatic decompensation.

Endoscopic treatment for gastroesophageal varices in patients with cirrhosis: a survey comparing between developed and developing countries

BACKGROUND

In this survey, we compared endoscopists' approach to treatment of gastroesophageal varices (GOV) in patients with cirrhosis between developed and developing countries. The objective of this study was to undertake a comparative analysis of the approaches employed by endoscopists in developed and developing countries with regard to the treatment of GOV in patients with cirrhosis.

METHODS

Between Jan 2019 to Aug 2019, we administered a questionnaire-based online survey internationally via e-mail. A total of 148 endoscopists from five countries were invited to participate in the survey, and 93 responses were received (response rate: 62.8%). The questionnaire covered several aspects: characteristics of the respondents, primary prophylactics, endoscopic therapy, and secondary prophylactics for acute variceal bleeding (AVB). The answers were compared between developed and developing countries using the chi-square test. For all tests, a P value of < 0.05 was considered significant.

RESULTS

There was a significant difference between developed and developing countries in practice settings (P = 0.001), the years of independent gastroenterology or endoscopic practice (P = 0.036), treating non-hemorrhagic large gastric varices with medicine (P = 0.019), and selection of preferred initial endoscopic therapy for active gastric fundic variceal bleeding (P = 0.015). Notably, developed and developing countries did not significantly differ in terms of treatment of non-hemorrhagic esophageal varices (P = 0.076), initial endoscopic therapy for active gastric cardia variceal bleeding (P = 0.272), timing of secondary prophylaxis (P = 0.104), timing of endoscopy (P = 0.073), measures for secondary prophylaxis (P = 0.166), and basis for the selection of management preferences (P = 0.278).

CONCLUSION

There were some differences in the practice of endoscopists for GOV in patients with cirrhosis between developing and developed countries. We speculate that these differences may affect the costs, management of primary bleeding, and chances of rebleeding in GOV. Furthermore, the equipment and technical conditions of different hospitals may also significantly influence the endoscopist's choice of treatment modality. We hope that future studies will place greater emphasis on this aspect as continuing education of and providing updated equipment to endoscopists are of paramount importance.

Liver Cirrhosis: ancient disease, new challenge

Liver cirrhosis is a common cause of morbidity and mortality worldwide. Excessive alcohol consumption and metabolic associated steatotic liver disease are the most common etiological factors of cirrhosis in our region. Cirrhosis occurs in two well-differentiated phases, compensated and decompensated, depending on the absence or presence of complications, respectively. Current therapeutic strategies are aimed at controlling these complications (such as ascites, hepatic encephalopathy, bacterial infections, or digestive hemorrhage, among others) or performing a liver transplant if there are no contraindications. However, it is important to eliminate the etiological factor responsible for the disease, as this can lead to the disappearance of complications, a state known as recompensation. This article proposes an updated review of the epidemiology of cirrhosis and its main causes, and offers an overview of the clinical features and treatment of the disease's complications, in addition to outlining future lines of research in this field.

Elevated platelet distribution width and diabetes may serve as preoperative predictors of microvascular invasion in primary hepatocellular carcinoma

BACKGROUND AND OBJECTIVE

Hepatocellular carcinoma (HCC) is one of the malignancies with increasing incidence globally, and microvascular invasion (MVI) is a crucial determinant of prognosis in patients. This study aimed to investigate platelet distribution width (PDW) and diabetes mellitus as indicators for predicting preoperative MVI in HCC, providing more accurate predictive tools for clinicians to guide treatment strategies and improve patient survival and quality of life.

METHODS

A retrospective study was conducted, including 1357 patients who underwent hepatectomy for HCC between January 2008 and December 2014 at the Eastern Hepatobiliary Surgery Hospital in China. Clinical, pathological, and radiological data, including PDW and diabetes status, were collected. Univariate and multivariate logistic regression analyses were performed to identify risk factors for MVI and establish a predictive model. The predictive performance of the model was evaluated through nomograms and internal validation.

RESULTS

Univariate analysis revealed significant associations between MVI and diabetes mellitus, presence of liver cirrhosis, prealbumin level, tumor diameter, number of tumors, HBV DNA viral load > 104, and PDW ≥ 17. Multivariate logistic regression analysis identified diabetes mellitus, liver cirrhosis, prealbumin level, tumor diameter, number of tumors, HBV DNA viral load > 104, and PDW ≥ 17 as independent risk factors for MVI. Based on these findings, a predictive model was established, demonstrating high predictive accuracy and stability in both the training and validation cohorts.

CONCLUSION

This study confirmed PDW and diabetes mellitus as reliable indicators for predicting preoperative MVI in HCC and established a corresponding predictive model. Future research should further explore the underlying mechanisms and enhance clinical validation to advance the field of HCC treatment.

Portal Vein Thrombosis in Patients Without Cirrhosis: Current Practical Approaches and Treatment Strategies

Portal vein thrombosis in non-cirrhotic individuals, although uncommon, is an increasingly explored condition that affects mainly young people, consequently representing a significant disease burden. Reports primarily including western European populations have recently shed light regarding the pathophysiology, risk factors, natural history, treatment, and prognosis of this entity. Underlying predisposing conditions are documented in ~70% of cases, encompassing local risk factors, inherited and acquired thrombophilia, cancer, and systemic inflammatory conditions. Non-cirrhotic portal vein thrombosis can cause significant portal hypertension in the acute setting, but, more frequently, significant portal hypertension-related complications arise when the condition becomes chronic and portosystemic collaterals develop, increasing the risk for variceal bleeding and ascites. The diagnostic approach to screen for underlying thrombophilia remains a challenge, and recommendations in this regard, although scarce and backed by scarce evidence, have changed notably in the last years, leaning toward a universal screen in patients who develop this condition without a clear provoking factor. Recently, studies have shown that long-term anticoagulation may be appropriate even in the absence of clear provoking factors or underlying thrombophilia. Future studies should address which patients may benefit from this approach, which patients may not need it, and what the most appropriate strategies are to approach patients who do not recover portal vein patency with anticoagulation to further prevent portal hypertension-related complications.

Liver function estimation using multiphase hepatic CT: diagnostic performance of iodine-uptake and volumetric parameters

OBJECTIVES

To investigate whether multiphase hepatic CT can predict liver function measured with indocyanine-green-retention test (ICG-R15) and identify patients with severe liver dysfunction contraindicating major hepatectomy, defined as ICG-R15 ≥ 20%, compared to technetium-99m-galactosyl serum albumin (99mTc-GSA) scintigraphy.

MATERIALS AND METHODS

This retrospective study included 118 patients (84 men, mean age, 69.4 ± 11.3 years) who underwent ICG-R15, 99mTc-GSA, and multi-phase CT including early portal-venous-phase and 3-min delayed-phase. CT-derived extracellular volume fraction (ECV), iodine washout rate (IWR), liver and spleen volumes normalized by body-surface-area (LV/BSA and SpV/BSA, respectively), and 99mTc-GSA-derived blood clearance index (HH15) and liver receptor index (LHL15) were quantified. Each parameter was compared between ICG-R15 ≥ 20% (n = 22) and ICG-R15 < 20% (n = 96) groups. Correlations with ICG-R15 were analyzed. The diagnostic performance to predict ICG-R15 ≥ 20% was assessed with areas under the receiver operating characteristic curve (AUC). Multivariable logistic regression analysis was used to identify independent CT predictors, and combined performance was determined.

RESULTS

In the ICG-R15 ≥ 20% group, IWR (p < 0.001), LV/BSA (p = 0.026), LHL15 (p < 0.001) were lower and ECV (p = 0.001), SpV/BSA (p = 0.005), and HH15 (p < 0.001) were higher compared to ICG-R15 < 20% group. ICG-R15 showed positive correlations with ECV (r = 0.355), SpV/BSA (r = 0.248), and HH15 (r = 0.385), while negative correlations with IWR (r = -0.523), LV/BSA (r = -0.123, not statistically significant), and LHL15 (r = -0.504). The AUC of ECV, IWR, LV/BSA, SpV/BSA, HH15, and LHL15 were 0.719, 0.845, 0.653, 0.694, 0.844, and 0.878, respectively. IWR, SpV/BSA, and LV/BSA were independent predictors, with a combined AUC of 0.924.

CONCLUSION

IWR predicted liver function better than ECV and hepatosplenic volumetry. The combined IWR and volumetry yielded an accurate prediction of severe liver dysfunction.

KEY POINTS

Question Despite the widespread use of multiphase CT in patients with hepatobiliary diseases, its potential role in assessing liver function has been scarcely evaluated. Findings Iodine washout rate (IWR), liver volume indexed by body surface area, and spleen volume indexed by body surface area were independent predictors for severe liver dysfunction. Clinical relevance Combined IWR and hepatosplenic volumetry on routine hepatic CT may help assess hepatic function for optimizing treatment strategies and predicting patient prognosis.

Risk Factors for Intrahepatic Distant Recurrence After Radiofrequency Ablation for Hepatocellular Carcinoma

AIM

The incidence of intrahepatic distant recurrence (IDR) of hepatocellular carcinoma (HCC) still remains high after radiofrequency ablation (RFA). However, serum alpha-fetoprotein (AFP) has insufficient screening power. This study aimed to identify risk factors for IDR in patients with post-RFA HCC.

METHOD

A total of 112 patients with early-stage HCC who underwent RFA were divided into the IDR (n = 51) and non-IDR groups (n = 61). Serum samples were analyzed within 2 months after RFA.

RESULTS

The mean follow-up duration was 30.1 months. The recurrence-free survival rates at 1, 3, and 5 years were 20.8%, 42.4%, and 54.2%, respectively. The 1- and 5-year overall survival rates were 97.3% and 87.3%, respectively. Univariate and multivariate analyses revealed that the neutrophil-to-lymphocyte ratio [NLR, hazard ratio (HR) 2.40; 95% confidence interval (CI) 1.44-3.99] and lens culinaris agglutinin a-reactive fraction of alpha-fetoprotein (AFP-L3, (HR 1.02; 95% CI 1.01-1.04) were independently associated with post-RFA IDR. The cumulative recurrence rates at 5 years in the high NLR (≥ 2.24) and high AFP-L3 (≥ 0.2 ng/mL) groups were significantly higher than those in the low NLR (< 2.24) and low AFP-L3 (< 0.2 ng/mL) groups, respectively. The predictive accuracies of NLR, AFP-L3, and a composite index based on AFP-L3, and NLR for IDR were 66.2% (37.3% sensitivity, 95.1% specificity), 64.3% (47.1% sensitivity, 80.3% specificity), and 75.6% (68.6% sensitivity, 75.4% specificity), respectively.

CONCLUSION

The combined model had significantly better prediction performance than either NLR or AFP-L3 alone. The NLR combined with an absolute AFP-L3 level is an effective marker for IDR in patients with post-RFA HCC.

Simvastatin and Rifaximin in Decompensated Cirrhosis: A Randomized Clinical Trial

Importance

There are no useful treatments to prevent the development of severe complications of liver cirrhosis. Simvastatin and rifaximin have shown beneficial effects in liver cirrhosis.

Objective

To assess whether simvastatin combined with rifaximin improves outcomes in patients with decompensated cirrhosis.

Design, Setting, and Participants

Double-blind, placebo-controlled, phase 3 trial conducted among patients with decompensated cirrhosis in 14 European hospitals between January 2019 and December 2022. The last date of follow-up was December 2022.

Interventions

Patients were randomly assigned to receive simvastatin, 20 mg/d, plus rifaximin, 1200 mg/d (n = 117), or identical-appearing placebo (n = 120) for 12 months in addition to standard therapy, stratified according to Child-Pugh class B or C.

Main Outcomes and Measures

The primary end point was incidence of severe complications of liver cirrhosis associated with organ failure meeting criteria for acute-on-chronic liver failure. Secondary outcomes included transplant or death and a composite end point of complications of cirrhosis (ascites, hepatic encephalopathy, variceal bleeding, acute kidney injury, and infection).

Results

Among the 237 participants randomized (Child-Pugh class B: n = 194; Child-Pugh class C: n = 43), 72% were male and the mean age was 57 years. There were no differences between the 2 groups in terms of development of acute-on-chronic liver failure (21 [17.9%] vs 17 [14.2%] patients in the treatment and placebo groups, respectively; hazard ratio, 1.23; 95% CI, 0.65-2.34; P = .52); transplant or death (22 [18.8%] vs 29 [24.2%] patients in the treatment and placebo groups, respectively; hazard ratio, 0.75; 95% CI, 0.43-1.32; P = .32); or development of complications of cirrhosis (50 [42.7%] vs 55 [45.8%] patients in the treatment and placebo groups, respectively; hazard ratio, 0.93; 95% CI, 0.63-1.36; P = .70). Incidence of adverse events was similar in both groups (426 vs 419; P = .59), but 3 patients in the treatment group (2.6%) developed rhabdomyolysis.

Conclusions and Relevance

The addition of simvastatin plus rifaximin to standard therapy does not improve outcomes in patients with decompensated liver cirrhosis.

Role of Spleen Stiffness Measurements with 2D Shear-Wave Elastography for Esophageal Varices in Patients with Compensated Advanced Chronic Liver Disease

Background/Objectives: Esophageal varices (EVs) represent an important portal hypertension complication in patients with compensated advanced chronic liver disease (cACLD). Although upper gastrointestinal endoscopy is currently the gold standard for EV diagnosis, recent guidelines recommend non-invasive approaches to assess EV risk in cACLD patients to reduce unnecessary endoscopies. Our study aims to evaluate spleen stiffness measurement (SSM) using 2D shear-wave elastography (2D-SWE) as a non-invasive predictor of EV presence and severity in patients with cACLD. Methods: We included 73 cACLD patients referred to our liver clinic over one year. SSM and liver stiffness measurement (LSM) were performed using 2D-SWE, with specific cut-off values applied to rule in or rule out clinically significant portal hypertension (CSPH) according to Baveno VII consensus criteria. Upper gastrointestinal endoscopy was performed in all patients to confirm EV presence and grade. Results: Among all patients, 49.3% had no EV, while 50.7% presented with different EV grades (15.1% grade I, 13.7% grade II, 9.6% grade III, and 12.3% grade IV). A strong correlation was observed between elevated SSM values and EV presence, with SSM values > 32.8 kPa highly suggestive of EV (AUROC = 0.95, 95% CI: 0.909-0.995, p < 0.001). SSM values exceeding 40.4 kPa were associated with more advanced EV grades. Combining LSM and SSM improved diagnostic accuracy, effectively stratifying EV risk without invasive procedures. Conclusions: SSM via 2D-SWE is a promising, non-invasive tool for EV prediction in cACLD, aligning with Baveno VII recommendations to minimize unnecessary endoscopies. Further validation is required to refine diagnostic thresholds and expand applicability across different chronic liver disease etiologies.

Management of gastrointestinal bleed in the intensive care setting, an updated literature review

Gastrointestinal (GI) bleeding is a critical and potentially life-threatening condition frequently observed in the intensive care unit (ICU). This literature review consolidates current insights on the epidemiology, etiology, management, and outcomes of GI bleeding in critically ill patients. GI bleeding remains a significant concern, especially among patients with underlying risk factors such as coagulopathy, mechanical ventilation, and renal failure. Managing GI bleeding in the ICU requires a multidisciplinary approach, including resuscitation, endoscopic intervention, pharmacologic therapy, and sometimes surgical procedures. Even with enhanced management strategies, GI bleeding in the ICU is associated with considerable morbidity and mortality, particularly when complicated by multi-organ failure. This review reiterates the need for adequate resuscitation and interventions in managing GI bleeding in critically ill patients, aiming to enhance survival rates and improve the quality of care within the ICU setting.

Liver stiffness measurement trajectory analysis for prognosis in patients with chronic hepatitis B and compensated advanced chronic liver disease

INTRODUCTION AND OBJECTIVES

Liver stiffness measurements (LSMs) offer a noninvasive method for monitoring liver disease development. This study evaluated the prognostic value of different LSM trajectories in chronic hepatitis B (CHB) and compensated advanced chronic liver disease (cACLD) patients.

MATERIALS AND METHODS

We retrospectively analyzed 1272 CHB and cACLD patients with at least two LSMs, applied group-based trajectory modeling (GBTM) to identify distinct LSM trajectories, and used a Cox model to analyze their associations with liver-related events (LREs) and mortality risk.

RESULTS

Patients were categorized into five groups with distinct LSM trajectories: 67 (8.5 %), 13 (11 %), 36 (23.5 %), 34 (27.6 %) and 23 (25.0 %) developed LREs in Groups 1-5. The low stable trajectory (Group 3), the medium gradual decrease trajectory (Group 4) and high quickly decrease followed by increase trajectory (Group 5) had higher LREs risks than the low gradual decrease trajectory (Group 1) (adjusted HRs 2.26, 2.39, 2.67; 95 % CIs 1.50-3.40, 1.57-3.66, 1.61-4.43, respectively). Similar elevated risks were observed for hepatic decompensation, hepatocellular carcinoma (HCC), liver-related and all-cause mortality, except that there was no significant difference in the risk of HCC between Groups 4 and 1 (aHR 0.66, 0.36-1.23). When comparing Group 1 with the medium quickly decrease trajectory (Group 2), no significant differences were noted in the prognosis (P > 0.05). Notably, age over 40, high LSM, low PLT, and high total bilirubin were linked to high-risk trajectories (Groups 3-5).

CONCLUSIONS

Monitoring LSM trajectories improves prognostic prediction in CHB and cACLD compared with single measurements and may guide personalized treatment strategies.

Long-term outcomes of Yttrium-90 transarterial radioembolization for patients with hepatocellular carcinoma

AIMS

We retrospectively assessed the long-term outcomes of Yttrium-90 (90Y) transarterial radioembolization (TARE) for hepatocellular carcinoma (HCC), focusing on overall survival (OS), radiological response, and safety.

METHODS

We included patients with HCC treated with 90Y TARE at a single center between January 2012 and December 2021 with measurable lesions and a minimum of 2 years of follow-up. Only the former was analyzed for patients with multiple TARE. The primary endpoints were long-term OS, radiological response, and safety; the secondary endpoints included predictors of OS and response, with emphasis on dosimetry. The collected data included demographics, laboratory test results, liver function, and tumor staging. Radiological response was evaluated 3-6 months post-TARE using the modified RECIST (mRECIST) criteria. OS was calculated from TARE until death or censoring. Univariate logistic regression was used to identify the predictors of complete radiological response and OS. Dosimetry was analyzed to determine correlations with mRECIST response.

RESULTS

Among 142 patients (median age 66.8, cirrhotic 92.3%; M: F = 121:21), a median OS of 16.68 months was achieved, with a complete radiological response in 31% (44/142). OS was strongly correlated with radiological response (p < 0.001). Absorbed dose ≥ 234.6 Gy was associated with complete response (p = 0.017) but not with survival (p = 0.102). Rising alpha-fetoprotein levels (p = 0.017) and worsening Child-Pugh scores post-TARE (p = 0.044) were independent predictors of mortality.

CONCLUSION

A complete radiological response is crucial for long-term survival, highlighting the need for dosimetry optimization in TARE for HCC.

Feasibility of shear wave elastography (2D -SWE) to evaluate cristalline lens in healthy dogs

BACKGROUND

2D shear wave elastography (2D SWE) is an emerging technique in veterinary medicine able to assess tissue stiffness in a non-invasive way. Nowadays no report is yet available about its application in assessing the mechanical properties of canine lenses.

OBJECTIVES

This study aimed to evaluate the repeatability and reproducibility of 2D SWE in assessing normal lens elasticity in healthy and ageing dogs.

METHODS

Trans-corneal lens 2D SWE was performed under physical restraint on 33 dogs by two operators who collected triplicate kPa and m/s measures, with the aim to assess reproducibility and reliability of the technique, followed by the evaluation of eventual difference of stiffness in different ages (G1 < 1.5 years, G2 1.5 years-7 years and G3 > 7 years). The project has been approved by the CEISA Ethical Committee (Prot. N. 12/2019 361 CEISA). Written informed consent was obtained by all the owners.

RESULTS

Mean elasticity values were respectively 4.78 ± 1.48 m/s and 74.9 ± 43.7 kPa for the left eye and 4.45 ± 0.98 m/s and 75.9 ± 43.6 kPa for the right eye. Despite a slight difference observed in the measurements obtained in m/s between the two operators, the intra-observer assessment was excellent in the overall population of dogs for both values in KPa and m/s, as well as the inter-observer one (ICC > 0.75). All the sCV% computed evidence a low measurement dispersion (< 12%). Mean lens stiffness for G1 was 3.1 ± 0.5 m/s and 28.9 ± 9.3 kPa, for G2 4.61 ± 0.62 m/s and 65 ± 18.4 kPa and for G3 6.46 ± 0.36 m/s and 126 ± 14.5 kPa; a significant difference P (< 0.001) was detected between all the groups.

CONCLUSIONS

It can be concluded that 2D SWE is a rapid and non-invasive US-based technique able to assess lens mechanical properties in companion animals since it is characterized by high reliability and reproducibility, providing also information regarding lens stiffness in aging dogs.

Establishment and validation of a nomogram for predicting esophagogastric variceal bleeding in patients with liver cirrhosis

BACKGROUND

Patients with decompensated liver cirrhosis suffering from esophagogastric variceal bleeding (EGVB) face high mortality.

AIM

To investigate the risk factors for EGVB in patients with liver cirrhosis and establish a diagnostic nomogram.

METHODS

Patients with liver cirrhosis who met the inclusion criteria were randomly divided into training and validation cohorts in a 6:4 ratio in this retrospective research. Univariate analysis, least absolute shrinkage and selection operator regression, and multivariate analysis were employed to establish the nomogram model. Calibration curve, the area under the receiver operating characteristic curve (AUC), and decision curve analysis (DCA) were applied to assess the discrimination, accuracy, and clinical practicability of the nomogram, respectively.

RESULTS

A total of 1115 patients were enrolled in this study. The nomogram was established based on white blood cells (P < 0.001), hemoglobin (P < 0.001), fibrinogen (P < 0.001), total bilirubin (P = 0.007), activated partial thromboplastin time (P = 0.002), total bile acid (P = 0.012), and ascites (P = 0.006). The calibration curve indicated that the actual observation results were in good agreement with the prediction results of the model. The AUC values of the diagnostic model were 0.861 and 0.859 in the training and validation cohorts, respectively, which were higher than that of the aspartate aminotransferase-to-platelet ratio index, fibrosis index based on 4 factors, and aspartate aminotransferase-to-alanine aminotransferase ratio. Additionally, DCA indicated that the net benefit value of the model was higher than that of the other models.

CONCLUSION

This research constructed and validated a nomogram with perfect performance for predicting EGVB events in patients with liver cirrhosis, which could help clinicians with timely diagnosis, individualized treatment, and follow-up.

Multicenter analysis on the correlation between the anatomical characteristics of hepatic veins and hepatic venous wedge pressure

BACKGROUND

Wedged hepatic venous pressure (WHVP) is a crucial variable for accurately assessing the hepatic venous pressure gradient (HVPG) and is vital for the diagnosis and prognostic evaluation of patients with portal hypertension (PH).

AIM

To investigate the anatomical characteristics of balloon-occluded hepatic venous angiography in patients with PH and analyze the relationship between the WHVP and portal venous pressure (PVP).

METHODS

This retrospective study included 877 patients with PH who met the inclusion criteria from January 2020 to June 2024. Routine and innovative hepatic venous angiography was performed during transjugular intrahepatic portosystemic shunt procedures to measure hepatic venous and PVPs. All patients' angiographic images were collected for analysis. The associations between WHVP and PVP in each group were analyzed via linear regression analysis, and a predictive model was established.

RESULTS

The 877 patients had a mean age of 52.6 ± 13.0 years, with 582 males and 295 females. Patients were categorized into four groups on the basis of their anatomical structure. All groups showed strong correlations between WHVP and PVP. The regression coefficient between the WHVP and PVP in the hepatic right vein-portal venous angiography group was 0.884 (P < 0.05); in the hepatic right vein-accessory hepatic venous angiography group, it was 0.721 (P < 0.05); in the hepatic right vein-middle hepatic venous angiography group, it was 0.344 (P < 0.05); and in the hepatic right vein-nonangiography group, it was 0.293 (P < 0.05).

CONCLUSION

The presence and anatomical classification of hepatic venous collaterals are key factors influencing the relationship between WHVP with and PVP. Based on the different anatomical classifications of hepatic veins, WHVP can be used to estimate PVP, improving the accuracy of PVP prediction.
