EASL Clinical Practice Guidelines for the management of patients with decompensated cirrhosis

Cardiac Evaluation in Liver Transplant Candidates

Liver transplantation (LT) is the only cure for patients with end-stage liver disease. With an increase in the prevalence of obesity and associated metabolic risk factors cardiovascular disease, in particular coronary artery disease is increasingly recognised in patients with liver cirrhosis. Identification and management of these cardiovascular risk factors may influence post-transplant clinical outcomes. A detailed assessment of patients' cardiovascular status is therefore crucial in the decision-making of patients for LT. Identification of patients with CAD requires risk stratification around perioperative and long term post-operative period. Advanced age, male sex, smoking diabetes mellitus, hypertension, obesity and metabolic-associated steatohepatitis (MASH) cirrhosis significantly increase the risk of coronary artery disease (CAD). Patients with these high-risk factors should undergo cardiac investigations with higher sensitivity to identify CAD. Patients with low-risk factors for CAD may undergo cardiac investigations with high specificity. Patients with cirrhosis may also suffer from conditions directly related to liver disease such as cirrhotic cardiomyopathy and porto-pulmonary hypertension, and conditions unrelated to liver disease such as arrhythmias. Rarely, valvular heart disease may be identified during transplant evaluation. Clinicians managing patients for liver transplantation should carefully evaluate cardiovascular risk and treat it appropriately prior to the surgery, to minimise post-transplant complication. A multidisciplinary approach involving transplant physicians, anaesthetists, cardiologists and transplant surgeons is strongly recommended.

A novel risk-predicted nomogram for acute kidney injury progression in decompensated cirrhosis: a double-center study in Vietnam

OBJECTIVES

Acute kidney injury (AKI) is commonly encountered in patients hospitalized for decompensated cirrhosis and is associated with prolonged hospital stays, increased treatment burden, and even mortality. The present study aimed to determine the prevalence of and develop a predictive nomogram for AKI in patients with decompensated cirrhosis.

METHODS

This cross-sectional, double-center study involved 544 patients hospitalized with decompensated cirrhosis. Acute kidney injury was diagnosed using American Gastroenterological Association's guidelines with one more criterion: an increase in serum creatinine ≥ 0.3 mg/dL within 48 h or an increase in serum creatinine ≥ 50% compared to baseline serum creatinine or when the urine output is reduced below 0.5 mL/kg/h for > 6 h. We used the Bayesian model averaging method find the optimal model for predicting AKI. A predictive nomogram was also developed to enable risk prediction.

RESULTS

The overall AKI prevalence was 26.7% (95% Confidence interval [CI] 25.7-27.7). The optimal model for predicting AKI included diuretic therapy (odds ratio [OR]: 5.55; 95%CI 3.31-9.33), infection (OR: 2.06; 95%CI 1.31-3.22), ascites (OR: 3.20; 95%CT: 1.67-6.13), Child-Pugh group C (OR: 2.91; 95%CI 1.84-4.62), serum potassium (OR per 1 mmol/L increase: 1.62; 95%CI 1.25-2.1) and serum chloride (OR per 1 mmol/L decrease: 1.03; 95%CI 1.01-1.06). The area under the receiver operating characteristic curve was 0.8, with a 95%CI ranging from 0.75 to 0.84.

CONCLUSIONS

Acute kidney injury was relatively common among patients hospitalized for decompensated cirrhosis. A novel nomogram-including diuretic therapy, infection, ascites, Child-Pugh group C, serum potassium and, serum chloride, was helpful for the selective screening of AKI in patients with decompensated cirrhosis.

Modulating respiratory mechanics and inflammation in hepatopulmonary syndrome: Aerobic exercise as a therapeutic strategy

INTRODUCTION

Aerobic exercise training positively modulates the immune system and improves lung function; however, its effects on respiratory system's elastic, resistive properties and interleukin-10 (IL-10) concentration in hepatopulmonary syndrome (HPS) remains unexplored. This study aimed to assess whether moderate-intensity aerobic (AE) training altered exercise capacity, respiratory mechanics and lung inflammation.

MATERIAL AND METHODS

Wistar rats were randomly assigned to SHAM, HPS, HPS + AE4, and HPS + EA8 groups. The EA4 group represents AE training for 4 weeks starting 7 days after HPS induction, whereas EA8 accounts for AE training for 4 weeks before and after HPS induction, both protocols practiced 3 times weekly. Exercise capacity, respiratory mechanics, lung and systemic inflammation, and lung morphology were assessed.

RESULTS

Moderate aerobic exercise significantly increased the maximal running capacity of the HPS animals. The training decreased tissue elastance by 19 % (p = 0.01 compared to SHAM) and reduced frequency-dependent respiratory reactance at 0.5 Hz, 0.75 Hz, and 1.25 Hz frequencies compared to HPS animals (p < 0.05 for all). For the HPS + EA4 and HPS + EA8 groups IL-10 plasma concentration increased by 23 % and 31 % compared to SHAM (p < 0.001 both) and by 38 % and 47 % compared to HPS (p < 0.01 both). Nonetheless, AE did not alleviate lung tissue remodeling induced by HPS.

CONCLUSIONS

Moderate-intensity aerobic training improved maximum running capacity, reduced HPS-induced respiratory mechanics derangements at the lung regional level, and increased systemic IL-10 concentration, although it did not ameliorate lung tissue remodeling.

Surrogate Markers of Intestinal Permeability, Bacterial Translocation and Gut-Vascular Barrier Damage Across Stages of Cirrhosis

BACKGROUND AND AIMS

Portal hypertension, gut barrier dysfunction, and pathological bacterial translocation are hallmarks of cirrhosis driving complications. As measuring gut barrier function is demanding, surrogate markers have been proposed, but their intercorrelation and applicability across different stages of advanced liver disease, particularly in acute-on-chronic liver failure (ACLF), are largely unknown.

METHODS

Proposed markers of gut barrier dysfunction and bacterial translocation were quantified in sera from 160 patients with cirrhosis across different disease stages of compensated and decompensated cirrhosis as well as from 20 patients in hepatic and portal vein serum before and after the insertion of transjugular intrahepatic portosystemic stent (TIPS) using enzyme-linked immunosorbent assay (ELISA).

RESULTS

Across all stages of liver disease, the gut-vascular barrier (GVB) marker plasmalemma vesicle protein-1 (PV-1) correlated with bacterial translocation markers endogenous endotoxin-core IgA antibodies (EndoCAb) and LPS-binding protein (LBP) but not with intestinal damage markers intestinal fatty acid binding protein (I-FABP) and zonulin-family peptides (ZFP). PV-1 and EndoCAb were higher in decompensated cirrhosis without further increase in ACLF. Among investigated markers, only I-FABP correlated with the portosystemic pressure gradient, and TIPS insertion significantly reduced portal concentrations within 24 h. Higher PV-1 levels indicated poor transplant-free survival in univariate and multivariable analysis.

CONCLUSIONS

Surrogate markers of bacterial gut barrier dysfunction and bacterial translocation like ZFP, LBP and EndoCAb appear of limited use in advanced stages of cirrhosis and are confounded by hepatic synthesis capacity, portal congestion and acute phase responses. The prognostic implications of circulating PV-1 in decompensated cirrhosis levels demand further investigation.

Three-Dimensional Transjugular Intrahepatic Portosystemic Shunt Geometry Predicts Shunt Dysfunction

BACKGROUND

Patients with decompensated cirrhosis are at risk of portal hypertension-related complications, such as refractory ascites or variceal bleeding. Transjugular intrahepatic portosystemic shunt (TIPS) insertion is the most effective treatment to reduce portal hypertension. However, patients are at risk for TIPS dysfunction.

AIMS

We aimed to investigate the prognostic value of three-dimensional (3D) TIPS geometry in predicting TIPS dysfunction.

METHODS

A total of 107 patients who underwent TIPS insertion between 2014 and 2019 and received a computed tomography (CT) scan after TIPS insertion during routine clinical practice were included. We used a semiautomated algorithm and multiplanar reconstructions of these CT scans to calculate parameters of 3D TIPS geometry. The primary outcome of this study was the development of TIPS dysfunction (defined as need for invasive TIPS revision). To identify predictors for the development of TIPS dysfunction, Cox regression analyses were performed with TIPS dysfunction as the endpoint.

RESULTS

Thirty-two patients developed TIPS dysfunction and were compared to the dysfunction-free 75 patients. A larger distance from the cranial TIPS stent end to the vena cava inferior (p < 0.001, HR 1.061, 95% CI 1.030-1.093) and the maximum stent curvature (p = 0.003, HR 1.020, 95% CI 1.007-1.034) were significantly associated with TIPS dysfunction in a multivariate Cox regression analysis.

CONCLUSION

A more pronounced stent curvature and a longer cranial stent distance from the inferior vena cava were identified as independent predictors of TIPS dysfunction. Interventionalists should choose a more central and less curved TIPS tract during the TIPS procedure to reduce the risk of development of TIPS dysfunction.

TRIAL REGISTRATION

This retrospective monocentric study includes patients from the NEPTUN cohort (registered at ClinicalTrials.gov; Identifier: NCT03628807).

Increasing Treatment Uptake for Chronic Hepatitis B in South America: A Comparative Analysis of Country-Specific and WHO 2024 Guidelines

The 2024 WHO guidelines for chronic hepatitis B (CHB) aim to expand and simplify treatment eligibility. We aimed to estimate treatment eligibility and uptake according to country-specific guidelines and evaluate treatment expansion based on the WHO guidelines. Treatment-naïve CHB patients from Argentina, Brazil, Chile and Uruguay referred to evaluation between January 2010 and June 2024 were retrospectively included. Treatment candidacy was evaluated according to both country-specific and WHO guidelines. A total of 719 patients with CHB, treatment naïve, were included (67.1% male; median age: 50.4 years; HBeAg-positive: 36.3%). The median HBV-DNA level was 43,000 (IQR 633-110,000,000) IU/mL, median ALT was 41 (IQR 23-99) U/L, 47.0% had an APRI > 0.5 and 21.1% had cirrhosis. According to country-specific guidelines, 56.9% (95% CI: 53.2-60.5) met the criteria for treatment. Antiviral treatment was initiated in 84.3% of eligible patients. The proportion of patients meeting treatment criteria under the WHO guidelines increased to 67.3% (95% CI: 63.8-70.6), resulting in a 10.4% (95% CI: 8.1-12.8) increase in treatment candidacy. Treatment expansion was significantly higher in women (15.2%; 95% CI: 10.2-20.1) than in men (8.1%; 95% CI: 5.4-10.7). According to WHO guidelines, a considerable proportion of CHB patients who do not meet country-specific criteria are eligible for antiviral therapy. Implementing WHO criteria can enhance treatment rates and advance efforts toward CHB elimination.

Emergency Plug-Assisted Retrograde Transvenous Obliteration for Active Bleeding from Ruptured Gastric Varices

PURPOSE

To evaluate the safety and effectiveness of emergency plug-assisted retrograde transvenous obliteration (PARTO) for active bleeding from ruptured gastric varices (GVs).

MATERIALS AND METHODS

Twenty-one patients with active bleeding from ruptured GVs were included in this retrospective study. Ten patients (47.6%) showed life-threatening hemorrhage (systolic blood pressure, <90 mm Hg) just before emergency PARTO. All patients underwent emergency PARTO after initial ineffective endoscopic cyanoacrylate injection (n = 9) or because endoscopic injection was not possible (n = 12).

RESULTS

Emergency PARTO was technically successful in all 21 patients. Mean fluoroscopic time was 30.8 minutes (range, 10-62 minutes). There were no procedure-related adverse events. Hemostasis was obtained in 20 (95.2%) of 21 patients immediately after PARTO. In 16 patients who underwent computed tomography (CT), complete thrombosis or obliteration of GVs and portosystemic shunt was observed. With the exception of 1 patient who underwent external transfer, 15 patients died within a mean of 196 days (range, 1-1,111 days), whereas 5 remained alive for a mean of 38.9 months (range, 17.1-74.2 months). Seven died within 30 days due to ischemia-related multiorgan failure (n = 5), hypovolemic shock (n = 1), or rapid progression of hepatocellular carcinoma (HCC) (n = 1). The causes of death in the remaining 9 patients were bleeding from esophageal varices (n = 2), liver failure (n = 2), and rapid progression of HCC (n = 5). The median patient survival time was 47 days (95% confidence interval, 0‒124 days). There was no case of rebleeding or recurrence of GVs.

CONCLUSIONS

Emergency PARTO appears to be a fast, safe, and effective treatment option to stop active bleeding from ruptured GVs; however, survival in this population is modest because of comorbidities and complications of shock.

Patient experience of alpha-1 antitrypsin deficiency-associated liver disease: a qualitative study

PURPOSE

To elicit the signs and/or symptoms, and impacts on daily living experienced by patients with alpha-1 antitrypsin deficiency-associated liver disease (AATD-LD).

METHODS

A preliminary "concept list" of signs and/or symptoms, and impacts was developed from a targeted literature review, patient blog posts, and clinician interviews. Subsequently, one-to-one concept elicitation interviews involving English-speaking, US adults with AATD-LD and a protease inhibitor (Pi) ZZ or MZ genotype were conducted by trained interviewers following a central Institutional Review Board-approved discussion guide. An AATD-LD conceptual model was developed based on these findings. Concepts were "most salient" if reported by ≥ 8 patients with a mean bothersomeness/disturbance rating of ≥ 5, or "highly salient" if reported by > 5- < 8 patients with a mean bothersomeness/disturbance rating of ≥ 5 (scale: 0-10, 0: not at all bothersome/disturbing; 10: extremely bothersome/disturbing).

RESULTS

Fifteen patients were interviewed (median [range] age: 57 [28-78] years; Pi*ZZ, n = 12; Pi*MZ, n = 3). Of 41 signs and/or symptoms, the most salient were fatigue/tiredness, respiratory infections, shortness of breath, confusion/difficulty concentrating, and edema. Highly salient signs and/or symptoms were abdominal swelling, acid reflux, sleep disturbance, vomiting, abdominal pain/tenderness, itchiness, and back pain. Of 16 impacts, the most salient were on work and employment, leisure activities, and relationships. Impacts on mobility were highly salient.

CONCLUSION

Several concepts were frequently reported as moderately/highly bothersome/disturbing. Further investigation of the experience of patients with AATD-LD in a large, diverse population across all fibrosis stages and genotypes is warranted. Clinical outcome assessments that capture salient concepts are needed.

Multisystem hemodynamic effects of terlipressin in cirrhosis: A scoping review

INTRODUCTION

Hepatorenal syndrome (HRS-AKI) is a serious complication of advanced liver disease. Pharmacologic options are limited in effectiveness, therefore liver transplantation is the definitive therapy. Early investigation into terlipressin as a first-line therapy for HRS-AKI has been promising but expected hemodynamic changes across organ systems in patients with cirrhosis have not been thoroughly examined.

METHODS

We conducted a scoping review of the literature including adult patients with cirrhosis who received terlipressin and hemodynamic parameters were recorded. Non-human studies, case reports, conference abstracts, and review articles were excluded. Searches were performed up to December 2024 in the following databases: MEDLINE, Embase, Cochrane Library, Scopus, Web of Science, and CINAHL.

RESULTS

Of 2022 studies retrieved, 56 studies met inclusion criteria. Heart rate, mean arterial pressure, and cardiac output were the most reported parameters. Pulmonary arterial pressure and wedge pressure were the next most common. Systemic vascular resistance, hepatic and renal measures such as resistive indices and portal pressure gradients had fewer studies. Studies reported decreased heart rate, increased mean arterial pressure, decreased cardiac output/index, and increased systemic vascular resistance. Other hemodynamic outcomes were more varied across studies.

CONCLUSIONS

Terlipressin exerts a variety of hemodynamic effects across organ systems and vascular beds. More studies are required to understand if any hemodynamic parameters might predict terlipressin response or adverse events.

Outcomes of transjugular intrahepatic portosystemic shunt creation for the management of portal hypertension complications in cancer patients

PURPOSE

To evaluate the outcomes of Transjugular Intrahepatic Portosystemic Shunt (TIPS) or variations of portosystemic shunt creation procedure in cancer patients with portal hypertension (PHTN).

MATERIALS AND METHODS

A single-center retrospective study was performed on cancer patients who underwent TIPS from September 2016 through June 2023. Forty consecutive cancer patients (mean age 61 years; 30 men, 10 women) were reviewed. For each patient, data regarding indication, the Child-Pugh (C-P) classification, international normalized ratio (INR), serum bilirubin level, creatinine level, and Model for End-Stage Liver Disease (MELD) score before the procedure and 1 month after the procedure were collected. Clinical efficacy was evaluated based on response, defined as the absence of significant variceal bleeding or clinically detectable ascites or hydrothorax following TIPS placement. Technical safety, complications, overall survival (OS), and incidence of hepatic encephalopathy (HE) were also assessed.

RESULTS

One month after TIPS, 31 (77.5%) patients had clinical response, and 9 (22.5%) had no response. The technical success rate was 100%. There were no major procedure-related complications. The primary indications for shunt creation were ascites in 18 (45%), variceal bleeding (47.5%), and hydrothorax (7.5%). The 1-, 3-, and 6-month mortality rates were 10%, 25%, and 40%, respectively. Among the 40 patients included, 24 (60%) had cirrhosis, most commonly due to hepatitis C infection, hepatitis B infection, alcoholic liver disease, or NASH. The remaining 16 patients (40%) were non-cirrhotic. The median MELD score pre-TIPS was 11.5 (range 6.5-20.1). C-P score before intervention included 4 (10%) cases in class A, 33 (82.5%) in B, and 3 (7.5%) in C. The median OS was 15.4 months (range 0.03-61 months) and significantly differed by C-P score for each group (P < 0.001). No significant correlations existed between OS and the MELD score or pre-TIPS laboratory data. Fourteen patients developed HE (34%) after the procedure, and only one patient (2.5%) required shunt reduction. Responders had significantly longer OS, with a median of 26.5 months compared to 1.1 months in non-responders (P < 0.001, 95% CI: 2.14-13.19). Nine (22.5%) patients had a stent placed through the tumor. Twenty-six patients (65%) had an unchanged C-P class after the procedure, while C-P worsened in 6 (15%) and improved in 4 (10%).

CONCLUSION

These findings suggest that TIPS and its variations for the portosystemic shunt creation can be a safe and effective option for managing portal hypertension complications in carefully selected cancer patients with relatively preserved liver function. The study demonstrated high technical success and encouraging clinical response rates. Additionally, overall survival appeared longer in patients who responded to TIPS compared to non-responders.

Mitochondrial Membrane Potential of CD8+ T Cells Predicts Bacterial Infection and Rapid Development of Acute-on-chronic Liver Failure in Cirrhotic Patients

Background and Aims

Patients with cirrhosis are at an increased risk of bacterial infection (BI), which is the most common precondition for acute-on-chronic liver failure (ACLF). In this study, we aimed to evaluate the ability of mitochondria-related indicators (mitochondrial mass and mitochondrial membrane potential (MMP)) of T cells in peripheral blood to predict BI and ACLF within 90 days in cirrhotic patients.

Methods

We prospectively studied mitochondria-related indicators in various T cells from 235 cirrhotic patients at the Second Hospital of Nanjing. The outcomes of interest were BI and ACLF.

Results

The restricted cubic spline analysis showed that the MMP of CD8+ T cells had a linear relationship with the risk of BI and ACLF (both P < 0.001). Multivariable Cox regression analysis demonstrated that the MMP of CD8+ T cells was an independent risk factor for both BI and ACLF (BI: hazard ratio 0.96, 95% confidence interval 0.94-0.98; P < 0.001; ACLF: hazard ratio 0.94, 95% confidence interval 0.90-0.97; P < 0.001). The MMP of CD8+ T cells exhibited better diagnostic efficacy than traditional indices in predicting BI (C index: 0.75). The MMP of CD8+ T cells, when combined with traditional models (Child-Turcotte-Pugh and model for end-stage liver disease score), improved their diagnostic efficiency in predicting both BI and ACLF. Additionally, the MMP of CD8+ T cells showed a significant negative correlation with inflammation-related markers (P < 0.05). Mitochondrial damage and abnormally activated mitochondrial autophagy were observed in CD8+ T cells from cirrhotic patients with low MMP.

Conclusions

The MMP of CD8+ T cells could serve as a valuable predictor of BI and ACLF within 90 days in cirrhotic patients.

Enteronephrohepatic Circulation of Bile Acids and Therapeutic Potential of Systemic Bile Acid Transporter Inhibitors

Together with carriers in liver and small intestine, kidney transporters function to conserve and compartmentalize bile acids in the enteronephrohepatic circulation. In patients with liver disease, systemic bile acid levels are elevated, undergo increased renal glomerular filtration, and contribute to the pathogenesis of cholemic nephropathy and acute kidney injury. In this review, we describe mechanisms for renal bile acid transport and highlight very recent discoveries that challenge current paradigms for the pathogenesis of cholemic nephropathy and renal tubule cast formation. We also discuss the therapeutic potential of inhibiting the kidney apical sodium-dependent bile acid transporter (ASBT) to redirect bile acids into urine for elimination, reduce hepatobiliary accumulation and systemic levels of bile acids, and treat cholemic nephropathy. In conclusion, a deeper understanding of the enteronephrohepatic bile acid axis is providing insights into novel strategies to protect both liver and kidney in patients with liver disease.

Ascites complications risk factors of decompensated cirrhosis patients: logistic regression and prediction model

OBJECTIVE

The study mainly aim at exploring the ascites risk factors among decompensated cirrhosis patients via constructing the prediction model of ascites incidence.

METHODS

Here, we recruited 148 decompensated cirrhosis patients for analysis, their laboratory tests and complications recorded. T-test, chi-square test, single-factor logistic regression, multi-factor logistic regression, and nomogram model were used to investigate the ascites occurred factors in decompensated cirrhosis patients with ascites. To validate the data analysis results, we applied the receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA) to evaluate the discrimination, calibration, and clinical usefulness of the prediction model, respectively.

RESULTS

Serum creatinine levels were higher in the cirrhotic ascites group than in the non-ascites group. The ascites group had lower albumin and serum sodium levels, as well as a lower incidence of variceal bleeding and varicose veins compared to the non-ascites group.

CONCLUSION

Varicose veins, variceal bleeding, and serum sodium levels are significant factors contributing to ascites development in cirrhosis. Furthermore, decreased serum albumin and elevated creatinine levels are important indicators of poor prognosis. Nomograms can improve clinicians' informed decision-making for patients with decompensated cirrhosis, ultimately reducing ascites risk.

In Vitro Immune Response of Mononuclear Cells to Multidrug-Resistant Escherichia coli

Infections caused by multidrug-resistant organisms (MDRO) are linked to poor outcomes, particularly in patients with cirrhosis. The underlying mechanisms are not fully understood and may involve a different immune response against MDRO. This study aimed to compare the in vitro immune response between multidrug-resistant (MDR) Escherichia coli and antibiotic-susceptible E. coli strains. Surface protein extract and DNA extract were obtained from MDR E. coli (n = 6) and antibiotic-susceptible E. coli (n = 6) strains isolated from infected patients with cirrhosis. The extracts were used to stimulate in vitro peripheral blood mononuclear cells from healthy donors. After 48 h, cytokine levels (IFN-γ, IL-1β, IL-10, IL-12p70, MCP-1, IL-8, IL-6, MIP-1α, and MIP-1β) were measured. We observed no significant differences in cytokine production between MDR and susceptible strains. However, we identified notable interindividual variability in cytokine production for most of the cytokines studied. Only IFN-γ and IL-6 in surface extract and MCP-1 in DNA extract showed similar levels across all donors. We conclude that the cytokine profiles induced by MDR E. coli in vitro were similar to those in susceptible strains. These findings suggest that the poor prognosis associated with MDR E. coli infections is not due to a differential immune response but rather to other factors.

Cyanoacrylate injection assisted by endosonographic mini-probe in the management of gastric varices: a single-center, retrospective cohort study

BACKGROUND

Gastric varices (GV) pose the potential risk of massive bleeding. Endoscopic ultrasound (EUS) guided real-time delivery of adhesives and devices has emerged as a promising therapeutic modality for GV but was limited in its generalizability due to the unavailability and lack of expertise of linear echoendoscopy. Therefore, we utilized the more readily available EUS mini-probe (EMP) in assisting cyanoacrylate (CYA) injection in the management of GV.

METHODS

This is a retrospective cohort study from a single tertiary medical center. One hundred and thirty-three eligible patients were divided into three groups based on the treatment modalities including EMP-guided CYA injection via a dual-channel gastroscope (EMP-D group), EMP-guided injection via a single-channel gastroscope (EMP-S group) and direct endoscopic injection (DEI group). The clinical characteristics, procedural parameters, outcomes, adverse events and follow-up data were analyzed.

RESULTS

An overall statistical significance was achieved in the number of puncture site (p < 0.001), the number of instant blood return upon puncture (p = 0.001), cyanoacrylate dose (p = 0.004), late rebleeding rate (p = 0.018), post-injection ulcer (p = 0.005), and non-rebleeding interval (p = 0.026) among the three groups. Patients in EMP-D group exhibited a lower rate of post-injection ulcer than those in DEI group (p = 0.009). Procedural time of EMP-D was shorter than that of EMP-S (p < 0.001). Less amount of cyanoacrylate was needed per reinjection session in EMP-D than in DEI (p = 0.002).

CONCLUSIONS

EMP-guided cyanoacrylate injection exhibited superior effectiveness and safety to DEI, while use of the dual-channel gastroscope further enhanced the precision and efficiency.

The burden of ascites in cirrhosis

OBJECTIVES

Liver cirrhosis is a leading cause of morbidity and mortality worldwide, with complications such as ascites, spontaneous bacterial peritonitis (SBP), and hepatorenal syndrome (HRS) significantly worsening prognosis. This paper aims to review the pathophysiology, diagnostic approaches, and management strategies for ascites and the complication of it, emphasizing the role of portal hypertension.

METHODS

We conducted a comprehensive review of the literature on liver cirrhosis, portal hypertension, ascites formation, and related complications. Existing evidence was evaluated and ranked using the GRADE system: A (high) to D (verly low). Recommendation strength was graded 1 (strong) or 2 (weak).

RESULTS

Portal hypertension is the key factor in ascites development. Non-invasive tools such as liver stiffness measurement (LSM) have proven to be effective in identifying patients at risk for clinically significant portal hypertension (CSPH), thus guiding treatment decisions. Carvedilol, recommended over propranolol, offers superior efficacy in reducing portal pressure. Diuretics, in combination with a moderate sodium-restricted diet, are the first-line treatment for ascites. However, refractory ascites requires advanced interventions. Spontaneous bacterial peritonitis (SBP) remains a major complication in patients with ascites, while hepatorenal syndrome - acute kidney injury (HRS-AKI) demands early recognition and timely vasoconstrictor therapy.

CONCLUSIONS

Liver cirrhosis and the complication of it significantly impact patient quality of life and survival. Portal hypertension is a critical driver of ascites and other complications, making early identification through non-invasive diagnostic methods essential for appropriate management. Medical treatments, including non-selective beta-blockers (NSBBs), diuretics, and advanced procedures, offer substantial benefits in controlling ascites and preventing further decompensation.

Beyond the Limits of Conventional Coagulation Tests: A Comprehensive Overview of ACLF-Related Coagulopathies

Acute-on-chronic liver failure (ACLF) is a complex and severe condition marked by multiple organ failure and high short-term mortality. Coagulopathy, a key component of ACLF, is characterized by rebalanced hemostasis with both hypo- and hypercoagulable features, increasing the risk of bleeding and thrombosis. Conventional coagulation tests, including prothrombin time (PT) and platelet count, fail to fully capture the complexity of coagulation dysfunction in ACLF. Advanced diagnostic tools, like viscoelastic tests (VETs), offer a more comprehensive assessment, yet they remain limited in evaluating endothelial dysfunction and fail to account for reduced levels of anticoagulant factors. Emerging therapeutic strategies targeting coagulopathies in ACLF hold promise, but their clinical efficacy remains unclear. A more nuanced approach to diagnosing and managing coagulopathy in ACLF is needed, incorporating advanced hemostatic profiling to better inform prognosis and guide treatment decisions.

CT-Derived spleen volume accurately diagnoses severe portal hypertension at HVPG thresholds of 16 mmhg

To investigate the diagnostic utility of a noninvasive method based on spleen volume for the accurate diagnosis of severe portal hypertension (PH). We enrolled 260 patients undergoing hepatic venous pressure gradient (HVPG) assessment and enhanced CT at Tianjin Third Central Hospital (December 2019-July 2023), with clinical data collected. Patients were stratified by HVPG levels: ≥16 mmHg (severe PH group) and < 16 mmHg (non-severe PH group). We included 120 cirrhotic patients who met the inclusion criteria. Splenic volume exhibited a linear correlation with HVPG (r = 0.364, p < 0.001). Univariate and multivariate logistic regression analyses identified spleen volume, age, and serum albumin as independent risk factors for severe PH (p < 0.05). Accordingly, a clinical diagnostic model was developed, named the "S-HVPG" score. The area under the curve (AUC) for the "S-HVPG" score was 0.803, with an optimal threshold of 0.694, achieving sensitivity, specificity, positive predictive value(PPV), and negative predictive value (NPV) of 78.8%, 74.3%, 88.2%, and 59.1%, respectively. The spleen volume-based "S-HVPG" scoring system introduces a novel, straightforward, noninvasive approach for diagnosing severe PH. A cutoff value of 0.694 for the S-HVPG score effectively distinguishes patients with severe PH from those with cirrhosis.

Investigating the Mechanism of the Fuzheng Huayu Formula in Treating Cirrhosis through Network Pharmacology, Molecular Docking, and Experimental Verification

Cirrhosis, characterized by liver fibrosis and structural remodeling, is a leading cause of liver cancer. The Fuzheng Huayu formula (FZHY) has been approved for treating liver fibrosis in China since 2002, but its effects and mechanisms on cirrhosis remain largely unknown. This study employed network pharmacology, molecular docking, and in vitro experiments to elucidate the specific mechanisms of FZHY against liver cirrhosis. First, intersecting genes between FZHY and cirrhosis were obtained from the Chinese Medicine System Pharmacology Database, the Swiss Target Prediction online platform, UniProt, GeneCards, DisGeNET, and OMIM. The STRING database was used to construct a protein-protein interaction network. Subsequently, Gene Ontology functional annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed, followed by molecular docking analysis to verify binding affinities between active ingredients and candidate targets. These analyses provided a theoretical basis for subsequent experimental research. Finally, we identified 117 FZHY target genes associated with cirrhosis and constructed a drug-component-target-cirrhosis-pathway network. Enrichment analysis revealed the AGE-RAGE signaling pathway in diabetic complications as a key pathway. Molecular docking showed that Isotanshinone II had the highest affinity for CHUK, IKBKB, and MAPK14. In vitro experiments demonstrated that Isotanshinone II dose-dependently reduced the mRNA expression of COL1A1 and α-SMA, as well as the protein levels of MAPK p38, IKKβ, and NF-κB p65 in LX-2 cells. These results revealed the underlying mechanism by which Isotanshinone II in FZHY inhibited LX-2 cell activation and collagen production through suppression of the MAPK/NF-κB signaling pathway. These findings support Isotanshinone II as a promising compound for cirrhosis targeting the MAPK/NF-κB pathway. Further research is warranted to explore the bioavailability of Isotanshinone II and to optimize its structure for clinical applications.

Xyloglucan protects the intestinal barrier and reduces bacterial translocation in experimental cirrhosis - A promising non-antibiotic strategy

BACKGROUND

Cirrhosis alters the intestinal barrier, increasing permeability and promoting bacterial translocation (BT). Norfloxacin is currently the only effective strategy to reduce BT, but the rise of multidrug-resistant bacteria highlights the need for new approaches.

AIMS

To evaluate the effect of xyloglucan, alone or with norfloxacin, on the intestinal barrier in cirrhotic rats with ascites.

METHODS

Decompensated cirrhosis with ascites was induced in 32 rats using CCl4. They were then administered xyloglucan (XG), norfloxacin (NF), xyloglucan+norfloxacin (XG+NF), or water (control) for one week. Parameters measured included BT incidence, endotoxemia, IFN-, IL-23, PV1/CD34 ratio, occludin and liver histology.

RESULTS

BT incidence was lower in all treatment groups (XG, NF, XG+NF) compared to controls, and significantly so in NF and XG+NF. Endotoxemia was reduced significantly in all treatment groups compared to controls, with values correlating significantly with BT incidence, occludin expression, IFN- levels, IL-23 levels, and PV1/CD34 ratio. There were no differences in IL-23 levels, but all treatment groups exhibited a decrease in IFN-, which was significant in the NF and XG+NF groups. All treatment groups showed significant increases in occludin levels and decreases in PV1/CD34 ratio compared to controls. All groups showed similar histological signs of cirrhosis.

CONCLUSIONS

Xyloglucan reduces intestinal mucosal inflammation, improves mucosal integrity and vascular permeability, and reduces endotoxemia and BT incidence. Xyloglucan alone showed similar results to norfloxacin; however, combining xyloglucan with norfloxacin does not provide additional benefits. These findings support evaluating xyloglucan as a new therapeutic strategy to prevent infections in cirrhosis.

EASL Clinical Practice Guidelines on extrahepatic abdominal surgery in patients with cirrhosis and advanced chronic liver disease

Extrahepatic surgery in patients with cirrhosis of the liver represents a growing clinical challenge due to the increasing prevalence of chronic liver disease and improved long-term survival of these patients. The presence of cirrhosis significantly increases the risk of perioperative morbidity and mortality following abdominal surgery. Advances in preoperative risk stratification, surgical techniques, and perioperative care have led to better outcomes, yet integration of these improvements into routine clinical practice is needed. These clinical practice guidelines provide comprehensive recommendations for the assessment and perioperative management of patients with cirrhosis undergoing extrahepatic surgery. An individualised patient-centred risk assessment by a multidisciplinary team including hepatologists, surgeons, anaesthesiologists, and other support teams is essential.

Clinical trajectories in liver cirrhosis: An evidence-based reappraisal for the internist

Over the last few years, the approach to clinical recognition and risk stratification of advanced liver disease has changed substantially, and liver cirrhosis has been increasingly conceptualized as a clinical rather than a histopathologic condition. In this Clinical Insight, we summarize the latest developments on recognition and management of 'clinically' advanced chronic liver disease.

Can "Attenuation Subtraction", a Computed Tomography Scan-Based Factor, be Used as a Predictor of High-Risk Esophageal Varices in Cirrhotic Patients? A Retrospective Cohort Study

Background and Aims

Liver cirrhosis is a severe condition that can result in complications such as portal hypertension and esophageal varices (EVs). While current guidelines recommend screening for EVs, existing procedures are often invasive, costly, and occasionally unreliable. This study aims to develop a CT-based predictor for identifying high-risk esophageal varices group (HRG) in cirrhotic patients, offering a noninvasive, safe, and cost-effective alternative that integrates seamlessly into routine follow-up without requiring additional resources or time.

Methods

The study retrospectively analyzed data from 2016 to 2021 of cirrhotic patients referred to a hospital in Tehran. Experienced professionals analyzed factors related to CT scans, and patients were categorized into high-risk and non-high-risk varicose veins groups by endoscopy. The main sample size for the study was 62 patients with an average age of 50.2 ± 11.5 years. Also, we aimed to determine a diagnostic cutoff and externally validated it in a separate statistical population (29 patients).

Result

The study found that liver attenuation subtraction, Child-Pugh score, and direct visualization of esophageal varices in CT scans were significant factors in predicting high-risk esophageal varices. The study showed that a liver attenuation subtraction of 14.5 HU (CI 95%: 0.949-1) with an inverse relationship could predict high-risk esophageal varices with high accuracy.

Conclusion

The study indicated that liver "Attenuation Subtraction" in CT scans distinguishes high-risk and non-high-risk esophageal varices. Furthermore, external validation demonstrated that this cutoff value is generalizable to other statistical populations. We pinpoint an indicator of high-risk esophageal varices in patients with cirrhosis devoid of invasiveness and peril and do not impose supplementary expenses or time beyond the customary monitoring of cirrhotic patients.

Update in clinical science: Autoimmune hepatitis

Autoimmune hepatitis (AIH) is an enigmatic, relatively rare disease with a variable spectrum of presentation whose pathogenesis, diagnosis and management remain a major challenge. We have performed a review of recent developments in basic science, epidemiology, clinical science, therapeutics, and regulatory science, evaluating the challenges associated with the application of translational research and clinical trial design to a condition that is a chameleon in nature, where outcomes range from relatively benign disease through cirrhosis and acute liver failure. This review is focused on developments from 2020 onwards so we can present a forward-looking view on the challenges and remaining questions that must be addressed to improve patient care and outcomes in AIH. We also outline areas of debate and offer insights into these areas.

Optimal Management of the Inpatient With Decompensated Cirrhosis

Over the past several years, there has been a wealth of new data pertaining to the management of complications of cirrhosis, resulting in several important updates to best practices and consensus guidelines. Despite these advancements and numerous recent targeted quality initiatives, hospitalizations resulting from complications of cirrhosis remain frequent, costly and associated with poor patient outcomes. An emphasis on evidence-based management of hospitalized patients with decompensated cirrhosis has the potential to decrease readmission rates and length of stay while improving overall patient outcomes. Herein, we provide an updated, evidence-based overview of the optimal inpatient management of the most frequently encountered complications associated with cirrhosis.

Serum pro-inflammatory cytokine interleukin-6 level is predictive of further decompensation and mortality in liver cirrhosis

AIM

Systemic inflammation drives the progression of portal hypertension in patients with liver cirrhosis. Interleukin-6 is a key mediator of the cytokine network in acute inflammation that stimulates the production of many acute phase reactants. In this study, we investigated the association between serum interleukin-6 and acute phase reactant levels and the disease stage and prognosis of patients with liver cirrhosis.

METHODS

A single-center retrospective cohort of 359 patients with liver cirrhosis was staged according to the symptomatic decompensation. Baseline serum C-reactive protein , interleukin-6, procalcitonin, and serum amyloid A protein levels were measured. The outcomes of further decompensation, hepatocellular carcinoma development, and mortality were identified during a 3.3-year median follow-up period.

RESULTS

Serum C-reactive protein , interleukin-6, and procalcitonin levels were significantly different across the stages. The multivariate Cox proportional hazards model identified serum interleukin-6 as an independent predictor of further decompensation in patients with compensated and the first single decompensated cirrhosis. Kaplan-Meier analyses showed that the probability of further decompensation was stratified by serum interleukin-6 level in a dose-dependent manner. In the entire cohort, serum interleukin-6 level also showed a significant association with liver-related and all-cause mortalities, but not with hepatocellular carcinoma development, independent of stage and liver disease severity indices.

CONCLUSIONS

Elevated levels of serum markers of systemic inflammation were associated with symptomatic decompensation, and serum interleukin-6 level is a predictor of further decompensation and mortality in patients with liver cirrhosis.

Endoscopic Glue Injection vs Glue Plus BRTO or TIPSS for Preventing Gastric Variceal Bleeding: A Randomized Controlled Trial

BACKGROUND AND AIMS

The study sought to compare the efficacy of endoscopic injection sclerotherapy with cyanoacrylate glue (EIS-CYA) vs EIS-CYA plus a radiologic intervention (RI) (either transjugular intrahepatic portosystemic shunt or balloon-occluded retrograde transvenous obliteration) for secondary prophylaxis in patients with liver cirrhosis who presented with acute variceal bleeding from cardiofundal varices. Primary outcome measure was gastric varix (GV) rebleed rates at 1 year.

METHODS

Consecutive cirrhosis patients with acute variceal bleeding from cardiofundal varices were randomized into 2 arms (45 in each) after primary hemostasis by EIS-CYA. In the endoscopic intervention (EI) arm, EIS-CYA was repeated at regular intervals (1, 3, 6, and 12 months), while in the RI arm, patients underwent transjugular intrahepatic portosystemic shunt or balloon-occluded retrograde transvenous obliteration followed by endoscopic surveillance.

RESULTS

GV rebleed rates at 1 year were higher in the EI arm compared with the RI arm: 11 (24.4%; 95% confidence interval [CI], 12.9%-39.5%) vs 1 (2.2%; 95% CI, 0.1%-11.8%) (P = .004; absolute risk difference: 22.2%; 95% CI, 8.4%-36.6%). GV rebleed-related mortality in the EI arm (8 [17.8%; 95% CI, 8.0%-32.1%]) was significantly higher than in the RI arm (1 [2.2%; 0.1%-11.8%]) (P = .030; absolute risk difference: 15.6; 95% CI, 2.9%-29.2%); however, there was no difference in all-cause mortality between the 2 groups (12 [26.7%; 95% CI, 14.6%-41.9%] vs 7 [15.6%; 95% CI, 6.5%-29.5%]). The number needed to treat to prevent 1 GV-related rebleed at 1 year was 4.5.

CONCLUSIONS

RI for secondary prophylaxis reduces rebleeding from GV and GV rebleeding-related mortality in patients with GV hemorrhage. (CTRI/2021/02/031396).

Higher Rate of Spontaneous Bacterial Peritonitis Recurrence With Secondary Spontaneous Bacterial Peritonitis Prophylaxis Compared With No Prophylaxis in 2 National Cirrhosis Cohorts

INTRODUCTION

Spontaneous bacterial peritonitis (SBP) bacteriology has changed over time. Reappraisal of primary SBP prophylaxis showed an increased rate of resistance in patients on primary prophylaxis with resultant discontinuation of this prophylaxis throughout the Veterans Affairs (VA). We aimed to re-evaluate the risk-benefit ratio of secondary SBP prophylaxis (SecSBPPr).

METHODS

Using validated International Classification of Diseases-9/10 codes, we used the VA Corporate Data Warehouse and the Non-VA National TriNetX database to identify patients in 2 different large US systems who survived their first SBP diagnosis (with chart review from 2 VA centers) between 2009 and 2019. We evaluated the prevalence of SecSBPPr and compared outcomes between those who started on SecSBPPr vs not.

RESULTS

We identified 4,673 veterans who survived their index SBP episode; 54.3% of whom were prescribed SecSBPPr. Multivariable analysis showed higher SBP recurrence risk in those on vs off SecSBPPr (hazards ratio 1.63 [1.40-1.91], P < 0.001). This was accompanied by higher fluoroquinolone resistance odds in SecSBPPr patients (odds ratio = 4.32 [1.36-15.83], P = 0.03). In TriNetX, we identified 6,708 patients who survived their index SBP episode; 48.6% were on SecSBPPr. Multivariable analysis similarly showed SecSBPPr increased SBP recurrence risk (hazards ratio 1.68 [1.33-1.80], P < 0.001). Both data sets showed higher SBP recurrence trends over time in SecSBPPr patients. Results remained consistent at 6-month and 2-year timepoints.

DISCUSSION

In 2 national data sets of >11,000 patients with SBP, we found that SecSBPPr was prescribed in roughly half of patients. When initiated, SecSBPPr, compared with no prophylaxis after SBP, increased the risk of SBP recurrence in multivariable analysis by 63%-68%, and this trend worsened over time. SecSBPPr should be reconsidered in cirrhosis.

Comparative efficacy of pre-emptive TIPS and elective TIPS in EGVB patients with cirrhosis: A single-center retrospective study

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) is the main method to prevent the rebleeding of esophagogastric varices. Many studies have demonstrated that pre-emptive TIPS (p-TIPS) is superior to medicine combined with endoscopic standard therapy in the efficacy of high-risk patients, but very few relevant studies reported whether p-TIPS is more effective than elective TIPS. This study aims to compare the efficacy and prognosis of p-TIPS and elective TIPS for the treatment of esophagogastric variceal bleeding (EGVB) patients with cirrhosis.

METHODS

In this retrospective study, clinical data of 92 patients with cirrhosis who accepted TIPS treatment after EGVB of cirrhosis were collected. According to the different times of TIPS, the patients were divided into the p-TIPS group and the elective TIPS group. The following information is documented: clinical manifestations and laboratory examination at 1, 3, and 6 months after the operation, survival state, the rates of rebleeding at 6 weeks and 6 months, and postoperative complications and serious adverse events during follow-up.

RESULTS

The Child-Pugh score ( P = 0.002) and MELD score ( P = 0.006) in the p-TIPS group were significantly lower than those in the elective TIPS group in the 6 th month after treatment. The rate of no gastric coronary vein embolization in the p-TIPS group was higher than in the elective TIPS group ( P = 0.034). The hospitalized days ( P < 0.001) and hospitalized costs ( P < 0.001) were significantly lower in the p-TIPS group than in the elective TIPS group. No significant differences were observed between the two groups concerning rebleeding, overt hepatic encephalopathy, ascites, complications, and serious adverse events, occurrence.

CONCLUSION

The p-TIPS contributes to liver function recovery and enhances patient survival benefits at 6-months postoperation in the treatment of EGVB compared with elective TIPS, without increasing the incidence of complications and adverse events.

Hepatic Recompensation Before Systemic Therapy for Hepatocellular Carcinoma Yields Comparable Survival to Compensated Cirrhosis

BACKGROUND AND AIMS

The survival outcomes associated with hepatic recompensation in patients with advanced hepatocellular carcinoma (HCC) treated with first-line systemic therapies remain unclear. We compared survival from the initiation of first-line systemic treatments for advanced HCC among patients with compensated, decompensated, and recompensated cirrhosis.

METHODS

A Latin American multicenter, prospective cohort study was conducted from 2018 to 2024, involving patients with HCC and Child-Pugh class A or B who received systemic therapy. At the time of first-line therapy, patients with cirrhosis were categorised as compensated (never decompensated), decompensated, or recompensated. Cox proportional hazards models were estimated.

RESULTS

Among 306 patients receiving first-line systemic therapy (sorafenib: 60.5%, atezolizumab + bevacizumab: 29.7%, lenvatinib: 9.1%), 240 had cirrhosis, with 30.4% having a history of hepatic decompensation. Of these, 57.5% (95% CI 45.4%-69.0%) achieved hepatic recompensation over a median period of 12 months. At the time of first-line therapy, 69.6% were compensated, 17.5% recompensated, and 12.9% decompensated. Metabolic-associated steatotic liver disease (MASLD) was the most common underlying aetiology in the recompensated group. Median survival was significantly shorter in the decompensated group (8.6 months) compared to the compensated group (17.2 months) [aHR 1.91 (95% CI 1.04-3.5); p = 0.03], without a significant difference between the recompensated and compensated groups [aHR 1.28 (95% CI 0.79-2.1); p = 0.31]. Tumour progression was the primary reason for treatment discontinuation, and similar access to second-line therapies was observed between the compensated and recompensated groups.

CONCLUSION

Patients with cirrhosis and advanced HCC who achieved hepatic recompensation might benefit from systemic therapies after a cautious observation period.

Comparison of Bacterial Infections in Patients With Cirrhosis Between Hospitals With and Without Liver Transplant in Catalonia

BACKGROUND AND AIMS

Infections by multidrug resistant (MDR) bacteria are increasing and vary across regions and hospitals. We aimed to assess the epidemiology, prevalence, and outcomes of bacterial infections in patients with decompensated cirrhosis, comparing liver transplant (LT) and non-LT centers in Catalonia.

METHODS

This is a multicenter retrospective study including all patients with decompensated cirrhosis and bacterial infections hospitalised between January 2021 and 2022 from 5 university hospitals in the Barcelona metropolitan area. Two of them were LT centres. Clinical, laboratory, microbiological data, and in-hospital mortality were collected.

RESULTS

A total of 576 infections were reported in 352 patients. LT centers had more health-related infections, recurrent infections, and septic shock than non-LT centers, while there were no differences in cirrhosis severity, acute-on-chronic liver failure (ACLF) or comorbidities. Although the most commonly isolated microorganisms and types of infection were similar in both centers, LT centers had higher rates of extended-spectrum beta-lactamase (12% vs. 6%), carbapenem (3% vs. 0%) and piperacillin-tazobactam resistant bacteria (14% vs. 7%). MDR rate was also higher in LT centers (38% vs. 25%, p = 0.02) and varied across hospitals (18%-42%, p < 0.05). Furthermore, in-hospital mortality was higher in LT centers (20% vs. 10%; p = 0.01). Independent predictors of in-hospital mortality were septic shock, ACLF, Child-Pugh, age, and leukocyte count.

CONCLUSIONS

Our study showed differences in epidemiology, prevalence of MDR infections, and outcomes across university hospitals, particularly between centers with and without LT. Further studies are warranted to unveil the nuances of bacterial infections across different healthcare institutions in Europe and elsewhere.

The Liver Intensive Care Unit

Major advances in managing critically ill patients with liver disease have improved their prognosis and access to intensive care facilities. Acute-on-chronic liver failure (ACLF) is now a well-defined disease and these patients can be fast-tracked for liver transplantation (LT) with good outcomes if there are no contraindications. In acute liver failure, plasma exchange has improved prognosis for patients not eligible for immediate transplant. Further advances in novel therapies and refinement of the criteria for early LT in ACLF and also clinical implementation of artificial intelligence tools will probably constitute the next major breakthroughs in critically ill patients with liver disease.

Liver Allograft Cirrhosis, Retransplant, and Mortality Secondary to Recurrent Disease After Transplant for MASH: A Systematic Review and Meta-analysis

BACKGROUND

Recurrent disease after liver transplant is well recognized for many diseases. Metabolic dysfunction-associated steatotic liver disease (MASLD) and steatohepatitis (MASH) are leading indications for liver transplant, and there is scarce knowledge about recurrence-related end outcomes such as retransplant and mortality. This project aims to assess the proportion of patients transplanted for MASH who develop recurrent disease and adverse clinical outcomes.

METHODS

A systematic review and pooled proportions meta-analysis was performed by searching the following databases: MEDLINE, Embase, Scopus, Web of Science Core Collection, and Cochrane Library. Inclusion criteria were studies discussing adult patients with liver transplants secondary to MASH or presumed MASH with recurrent disease-related outcomes. Outcomes were assessed in time frames from <6 mo to ≥5 y.

RESULTS

Of 5859 records, 40 were included (16 157 patients). Recurrent MASLD and MASH (28 studies each) occurred in frequencies of 35%-49% and 11%-24%, respectively. Fibrosis occurred in 4%-25% (13 studies). Recurrent disease-related cirrhosis (13 studies), graft failure (8 studies), and retransplant (9 studies) occurred in 0%-2%, 3%-9%, and 0%-1%, respectively. Recurrent disease-related hepatocellular carcinoma (1 study) and mortality (17 studies) both had a prevalence of 0%. Studies were of moderate or high quality using the Methodological Index for Non-Randomized Studies tool.

CONCLUSIONS

Recurrent MASLD and MASH after liver transplant occur frequently, but adverse clinical outcomes due to disease recurrence are infrequent, maybe due to insufficient data on long-term follow-up. Long-term outcomes after transplantation for MASLD appear favorable; however, identifying those more likely to have progressive recurrent disease leading to adverse clinical outcomes may allow for pre- and posttransplant interventions to improve outcomes further.

[Endo-Hepatology: New Endoscopic Solutions for Old Hepatological Problems]

With the rapid development of endoscopic ultrasound (EUS), diagnostic and therapeutic platforms have emerged that are applicable in hepatology. New tools such as EUS-guided portal pressure measurement (in combination with EUS-guided liver biopsy) or EUS-guided variceal obliteration using coils and glue present attractive procedures that can potentially overcome the limitations of current gold standards. In this review article, we provide an overview of these new 'endo-hepatology' techniques and highlight their current role in the treatment of liver diseases.

Understanding and Treating Hepatorenal Syndrome: Insights from Recent Research

Acute kidney injury (AKI) is a critical and often fatal complication in decompensated cirrhosis, significantly affecting inpatient survival rates. Hepatorenal syndrome (HRS), a distinct subtype of AKI, develops in individuals with advanced cirrhosis and portal hypertension. It is marked by progressive kidney dysfunction, poor prognosis, and frequently causes death before liver transplantation. The pathogenesis of HRS involves vasodilation of the splanchnic vessels, leading to overactivation of the endogenous vasoactive systems, circulatory dysfunction, and reduced renal perfusion, which ultimately impairs glomerular filtration. Recent studies have highlighted the role of systemic inflammation in exacerbating renal damage. Despite these changes, renal histology in HRS usually shows no significant abnormalities, and there is typically no hematuria, proteinuria, or abnormal findings on ultrasound. Common risk factors for HRS include spontaneous bacterial peritonitis, infections, and large-volume paracentesis without albumin infusion. Diagnosing HRS is challenging, particularly in distinguishing it from acute tubular necrosis, due to the absence of specific biomarkers. Treatment primarily involves vasoconstrictors such as terlipressin and albumin, with liver transplantation being the definitive therapeutic option. This review provides an updated understanding of HRS, addressing its pathophysiology, diagnosis, management, and future challenges, based on recent expert consensus.

Endoscopic variceal ligation combined with carvedilol versus endoscopic variceal ligation combined with propranolol for the treatment of oesophageal variceal bleeding in cirrhosis: study protocol for a multicentre, randomised controlled trial

INTRODUCTION

Liver cirrhosis and its severe complication, oesophageal variceal bleeding (EVB), pose significant health risks. Standard treatment for EVB combines non-selective beta-blockers (NSBB) with endoscopic variceal ligation (EVL). Carvedilol, an NSBB with additional benefits, is preferred for compensated cirrhosis. However, no randomised controlled trial (RCT) has compared carvedilol with propranolol, a conventional NSBB, in combination with EVL for secondary prophylaxis. This study aims to compare the effectiveness and safety of these treatments in preventing variceal rebleeding or death in patients with cirrhosis and EVB.

METHODS AND ANALYSIS

This multicentre, RCT is scheduled to begin in December 2024, with recruitment and follow-up continuing until December 2026. Eligible participants are patients with liver cirrhosis and EVB. Participants are randomly assigned in a 1:1 ratio to receive EVL combined with either carvedilol or propranolol. The primary endpoint is the incidence of variceal rebleeding or all-cause death. Secondary endpoints include all-cause death, liver-related death, each of the complications of portal hypertension (overt ascites, overt hepatic encephalopathy, spontaneous bacterial peritonitis, hepatorenal syndrome, portal vein thrombosis), hepatocellular carcinoma, changes in liver function (assessed by Child-Pugh and Model for End-Stage Liver Disease scores), changes in liver stiffness, changes in spleen stiffness, and adverse events. Subgroup and sensitivity analyses will be conducted to evaluate the consistency and robustness of the treatment effects. A total sample size of 524 patients (262 per group) is required to detect a significant difference between the treatment arms.

ETHICS AND DISSEMINATION

The study protocol has been approved by the ethics committee of the First Hospital of China Medical University (No. 2024-656-2). The study will follow the Declaration of Helsinki and Good Clinical Practice guidelines. The findings of this trial will be disseminated through peer-reviewed publications, conference presentations and healthcare professionals to guide future clinical practice.

Transjugular intrahepatic portosystemic shunt and non-selective beta-blockers act as friends or foe in decompensated cirrhosis: A comparative review

The management of portal hypertension and its complications, such as variceal bleeding, in patients with cirrhosis often involves the use of nonselective beta-blockers (NSBBs) and a transjugular intrahepatic portosystemic shunt (TIPS). Both treatment modalities have demonstrated efficacy; however, each presents distinct challenges and benefits. NSBBs, including propranolol, nadolol, and carvedilol, effectively reduce portal pressure, but are associated with side effects such as bradycardia, hypotension, fatigue, and respiratory issues. Additionally, NSBBs can exacerbate conditions such as refractory ascites, hepatorenal syndrome, and hepatic encephalopathy. In contrast, TIPS effectively reduces the incidence of variceal rebleeding, controlling refractory ascites. However, it is associated with a significant risk of hepatic encephalopathy, shunt dysfunction, and procedure-related complications including bleeding and infection. The high cost of TIPS, along with the need for regular follow-up and potential re-intervention, poses additional challenges. Furthermore, patient selection for TIPS is critical, as inappropriate candidates may experience suboptimal outcomes. Future studies comparing NSBBs and TIPS should focus on refining the patient selection criteria, enhancing procedural techniques, optimising combination therapies, and conducting long-term outcome studies. Personalised treatment approaches, cost-effectiveness analyses, and improved patient education and support are essential for maximising the use of these therapies.

Efficacy and safety of TACE combined with TKIs and PD-1 inhibitors in HCC patients with prior TIPS

Purpose

To compare the efficacy and safety of TACE combined with TKIs and PD-1 inhibitors between HCC patients with and without prior TIPS.

Methods

This retrospective propensity score matching (PSM) study included advanced HCC patients treated with prior TIPS followed by TKIs, PD-1 inhibitors, and TACE between January 2021 and January 2023. Patients were matched with a control group of HCC patients who had not undergone TIPS (non-TIPS). Outcome measures included objective response rate (ORR) using modified RECIST (mRECIST v1.1), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety assessed by CTCAE v5.0.

Results

A total of 172 patients were included before PSM. After PSM, 42 patients with prior TIPS were matched with 71 non-TIPS patients. ORR was 31.0% in the TIPS group and 57.7% in the non-TIPS group (p = 0.007), Both PFS and OS were longer in the non-TIPS group, with a median PFS of 7.9 months for TIPS patients versus 12.3 months for non-TIPS patients (hazard ratio [HR] = 2.253, p < 0.001), and a median OS of 13.5 months versus 21.1 months, respectively (HR = 2.282, p = 0.002). Treatment-related adverse events showed no significant differences between the two groups.

Conclusion

TACE combined with TKIs and PD-1 inhibitors showed lower efficacy in HCC patients with prior TIPS, but it remains a viable option, providing a favorable safety profile and effective disease control.

Management of hepatic encephalopathy following transjugular intrahepatic portosystemic shunts: Current strategies and future directions

Transjugular intrahepatic portosystemic shunts (TIPSs) are generally used for the management of complications of portal hypertension in patients with decompensated cirrhosis. However, hepatic encephalopathy (HE), which impairs neuropsychiatric function and motor control, remains the primary adverse effect of TIPS, limiting its utility. Prompt prevention and treatment of post-TIPS HE are critical, as they are strongly associated with readmission rates and poor quality of life. This review focuses on the main pathophysiological mechanisms underlying post-TIPS HE, explores advanced biomarkers and predictive tools, and discusses current management strategies and future directions to prevent or reverse HE following TIPS. These strategies include preoperative patient assessment, individualized shunt diameter optimization, spontaneous portosystemic shunt embolization during the TIPS procedure, postoperative preventive and therapeutic measures such as nutrition management, medical therapy, fecal microbiota transplantation, and stent reduction.

An Update on IL-22 Therapies in Alcohol-Associated Liver Disease and Beyond

Excessive alcohol consumption drives the development of alcohol-associated liver disease (ALD), including steatohepatitis, cirrhosis, and hepatocellular carcinoma, and its associated complications, such as hepatorenal syndrome. Hepatocyte death, inflammation, and impaired liver regeneration are key processes implicated in the pathogenesis and progression of ALD. Despite extensive research, therapeutic options for ALD remain limited. IL-22 has emerged as a promising therapeutic target because of its hepatoprotective properties mediated through the activation of the STAT3 signaling pathway. IL-22 enhances hepatocyte survival by mitigating apoptosis, oxidative stress, and inflammation while simultaneously promoting liver regeneration through the proliferation of hepatocytes and hepatic progenitor cells and the up-regulation of growth factors. Additionally, IL-22 exerts protective effects on epithelial cells in various organs affected by ALD and its associated complications. Studies from preclinical models and early-phase clinical trials of IL-22 agonists, such as F-652 and UTTR1147A, have shown favorable safety profiles, good tolerability, and encouraging efficacy in reducing liver injury and promoting regeneration. However, the heterogeneity and multifactorial nature of ALD present ongoing challenges. Further research is needed to optimize IL-22-based therapies and clarify their roles within a comprehensive approach to ALD management. This review summarizes the current understanding of IL-22 biology and its role in ALD pathophysiology and ALD-associated complications along with therapeutic application of IL-22, potential benefits, and limitations.

Efficacy and safety of terlipressin infusion during liver surgery: a meta-analysis

Although numerous studies have investigated terlipressin (TP) administration in liver surgery to mitigate bleeding, its efficacy remains controversial. This meta-analysis evaluates the effects of TP on estimated blood loss (EBL), blood transfusion requirements, and patient outcomes. We systematically searched PubMed, EMBASE, Cochrane Library, and Web of Science (WOS) for studies on perioperative TP use in liver surgery from their inception through February 2024. Only English-language publications were included. Primary outcomes included EBL and allogeneic blood transfusion volume. Twelve studies involving 988 eligible subjects were included. No significant differences were observed in EBL (weighted mean difference [WMD] =  - 99.09; 95% confidence interval [CI], - 318.41 to 120.24; P = 0.38), red blood cell (RBC) transfusion volume (standardized mean difference [SMD] =  - 0.10; 95% CI =  - 0.74 to 0.54; P = 0.76), or fresh frozen plasma (FFP) transfusion volume (SMD = 0.07; 95% CI =  - 0.24 to 0.37; P = 0.67). Subgroup analysis demonstrated that continuous TP infusion significantly reduced intraoperative EBL (WMD =  - 336.22; 95% CI =  - 562.13 to - 110.31; P = 0.004). TP infusion does not reduce intraoperative EBL or allogeneic blood transfusion requirements in liver surgery. However, continuous TP infusion may lower EBL.PROSPERO registration number: CRD42023450333.

Decompensated cirrhosis: an update of the BSG/BASL admission care bundle

Acute decompensated cirrhosis (DC) and acute-on-chronic liver failure are common reasons for hospital admission that have a high in-hospital mortality rate (10%–20%). Patients require a detailed assessment for precipitating factors and management of complications such as infections, ascites, acute kidney injury and hepatic encephalopathy. Multiple reports have demonstrated unwarranted variability in the care of patients with DC. In 2014, the British Society of Gastroenterology (BSG)/British Association for the Study of the Liver (BASL) DC care bundle (DCCB) was introduced to provide a structured approach for the management of patients with DC in the first 24 hours. Usage of the DCCB has been shown to improve care of patients with DC. However, despite evidence indicating the beneficial impact of the DCCB, overall usage across the UK was only 11.4% in a national audit. Our aim was to update the DCCB to incorporate recent advances in care and improve its usability and develop a strategy to improve its usage nationally. The updated bundle was developed by a multidisciplinary group of specialists from BSG, BASL and the Society for Acute Medicine with the quality of evidence supporting the bundle recommendations assessed using the Grading of Recommendation Assessment Development and Evaluation tool. Proposed minimum standards for audit were also developed. Finally, a strategy to promote usage of the bundle including education/training at a national and local level, improving accessibility for the bundle, and promotion of frameworks for use at an institutional level to improve and monitor utilisation of DCCB.

Spleen Stiffness Predicts the Risk of Liver-related Complications in Patients With Compensated Advanced Chronic Liver Disease

BACKGROUND & AIMS

The development of portal hypertension (PH) is a key prognostic factor in patients with compensated advanced chronic liver disease (cACLD). The gold standard for assessing PH is the hepatic venous pressure gradient measurement. However, noninvasive tools have gained significant importance in recent years, mainly liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE). Spleen stiffness measurement (SSM) by VCTE using a dedicated 100-Hz module has emerged as a promising non-invasive diagnostic tool, although data on its prognostic value remain limited. This study aimed to evaluate the accuracy of SSM, as measured by transient elastography, in predicting the risk of liver decompensation.

METHODS

A prospective study was conducted including patients with cACLD followed at a tertiary center from January 2020 to April 2024. All patients underwent liver and spleen VCTE (utilizing the 100-Hz module) performed by the same blinded operator. Patients were subsequently monitored at the same institution for the development of PH complications.

RESULTS

The study included 242 patients with cACLD, with a mean age of 63.0 ± 10.5 years and who were 78.5% male. The most common etiology was alcoholic liver disease (62.0%). The median LSM value was 21.9 kPa (interquartile range [IQR], 15.0-34.0 kPa), and the median SSM value was 38.9 kPa (IQR, 28.0-58.0 kPa). The median follow-up period was 501.5 days (IQR, 343.0-725.3 days). During this time, 28 patients (11.6%) developed liver decompensations, with 20 requiring hospital admission. SSM demonstrated good predictive capacity for the risk of liver decompensation (area under the curve, 0.823; 95% confidence interval, 0.742-0.904). Alongside LSM, SSM was an effective predictor of liver decompensation, with a cutoff of 50.0 kPa indicating a significantly increased risk of hepatic decompensation.

CONCLUSION

Noninvasive assessment using SSM may serve as an excellent tool for predicting the risk of liver-related complications and risk-stratifying patients with cACLD, thereby improving their management.

Multiplex PCR for Microbiological Testing in Patients with Peritoneal Dialysis- and Liver Cirrhosis-Related Peritonitis: Faster, but Less Sensitive

Background: We analyzed the performance of a multiplex PCR application (Unyvero IAI) in comparison to culture in a cohort of peritonitis patients undergoing peritoneal dialysis or with liver cirrhosis. Methods: We performed a single-center study of 47 patients with clinically suspected peritonitis and compared pathogen detection rates of culture and PCR. The main outcome of interest was a comparison of accuracy and time to final positive result. Results: In the total cohort, the pathogen detection rate in culture was 58.14% versus 34.88% in PCR (p = 0.03). Detection rates of bacteria in peritoneal dialysis patients were even higher by culture (70.83%) but comparably low by PCR (37.50%; p = 0.04). The majority of discordant results were in the Gram-positive spectrum (81.82%). Differential time to final positive result was 37.39 ± 16.75 h. Conclusion: Time gains by using PCR diagnostic have to be weighed against lower detection rates, mainly in Gram-positive infections.

Management of Ascites: AJR Expert Panel Narrative Review

Ascites can develop in the setting of a variety of pathologies. The approach to treatment depends on accurate determination of the underlying cause, for which fluid analysis plays a central role. In particular, the serum-ascites-albumin gradient serves as a primary diagnostic test for differentiating among causes, with certain additional fluid tests performed based on clinical suspicion. Treatment options range from nonspecific fluid removal, including large-volume paracentesis and tunneled peritoneal catheters, to targeted therapies (e.g., diuretics, transjugular intrahepatic portosystemic shunt, and lymphangiography). Societal guidelines exist for the approach to cirrhotic ascites, but the management of other less common causes remains less well defined. The goal of this AJR Expert Panel Narrative Review is to provide guidance for the diagnosis and management of ascites, based on available evidence and the authors' clinical experience.

Fluoroquinolones for the Prophylaxis of Spontaneous Bacterial Peritonitis in Patients with Liver Cirrhosis: Are They Losing Ground?

Spontaneous bacterial peritonitis (SBP) is the most common bacterial infection in cirrhotic patients. Historically, the bacterial spectrum was dominated by Gram-negative bacteria. However, recent studies showed that fluoroquinolone (FQ)-based prophylaxis promotes the intestinal overgrowth of Gram-positive bacteria and contributes to the selection of quinolone-resistant Gram-negative bacteria, increasing multidrug-resistant (MDR) organism infections. FQ resistance rates reach up to nearly one-third in community-acquired cases and 50% in hospital-acquired cases, raising concerns about FQ efficacy. Moreover, rare but serious side effects further limit FQ use. Predictive factors of FQ treatment failure have been identified, guiding management strategies. Rifaximin has emerged as a promising alternative for SBP prophylaxis, with encouraging results. This review aims to explore the shifting role of FQ-based SBP prophylaxis, focusing on the emerging concerns, side effects, and alternative strategies. While norfloxacin remains a first-line prophylactic in cirrhotic patients with low ascitic protein levels, its efficacy appears to be reduced in those with advanced liver failure or additional risk factors for MDR organisms. In these subgroups, alternative prophylactics, such as trimethoprim-sulfamethoxazole or rifaximin, may be preferable. We propose a risk-stratification approach to guide treatment selection, with further studies needed to refine these criteria.
