Abstract
Hepatocellular carcinoma (HCC) is the predominant form of primary liver cancer and the third contributor to malignancy-related deaths worldwide. The hepatic venous pressure gradient (HVPG), transient elastography-liver stiffness measurement (TE-LSM), and the association between TBS (tumor burden score), alpha-fetoprotein levels, and the Child-Pugh classification (TAC score) can serve as valuable prognostic indicators for these patients. Therefore, the main objective of our research was to analyze the prognostic value of the HVPG, TE-LSM, TBS, and TAC scores. An observational and survival study was conducted on 144 subjects. Our findings indicated that HVPG greater than 10 mmHg, AFP surpassing 400 ng/mL, an advanced C-P class, and low TAC score are independent predictors of overall survival. During the multivariate analysis, AFP serum levels and C-P class proved statistically significant. The present study revealed significant differences in overall survival between the two groups divided upon HVPG values and settled by the cutoff of 10 mmHg (p = 0.02). Moreover, by dividing the cohort into three groups based on the TAC score (very low, low, and moderate), statistically significant differences in overall survival were observed across the groups (p = 0.004).

Abstract
Bleeding from esophageal and gastric varices is a major factor of mortality in patients with portal hypertension. The gold standard for diagnosis of portal hypertension is hepatic venous pressure gradient determining the treatment algorithms and risk of recurrent bleeding. Combination of endoscopic methods and therapy is limited by varix localization and not always effective. In these cases, endovascular bypass and decoupling techniques are preferred. Early endovascular treatment of portal bleeding is effective for hemostasis and higher transplantation-free survival of patients. Early transjugular intrahepatic portosystemic bypass should be associated with 8-mm covered stents of controlled dilation. Combination of endovascular techniques reduces the complications of each technique and potentiates their positive effect. Endovascular treatment and prevention of portal bleeding should be determined by anatomical features of portal venous system.

Abstract
Hepatic venous pressure gradient (HVPG) is the gold standard for evaluating clinically significant portal hypertension (CSPH). However, reliable noninvasive methods are limited. Our study aims to investigate the diagnostic value of serum Golgi protein 73 (GP73) for CSPH in patients with compensated cirrhosis. The study enrolled 262 consecutive patients with compensated cirrhosis from three centers in China from February 2021 to September 2023, who underwent both serum GP73 tests and HVPG measurements. CSPH was defined as HVPG ≥ 10 mmHg. Diagnostic accuracy was evaluated using the areas under the receiver operating characteristic curve (AUC). The prevalence of CSPH was 56.9% (n = 149). There were significant differences between the CSPH and non-CSPH groups in the median serum GP73 level (126.8 vs. 73.1 ng/mL, p < 0.001). GP73 level showed a significant positive linear correlation with HVPG (r = 0.459, p < 0.001). The AUC for the diagnosis of CSPH using serum GP73 alone was 0.75 (95% confidence interval [CI] 0.68-0.81). Multivariate logistic regression analysis determined that the levels of GP73, platelets and international normalized ratio were independently associated with CSPH. The combination of these three markers was termed "IP73" score with an AUC value of 0.85 (95% CI 0.80-0.89) for CSPH. Using 0 as a cut-off value, the specificity and sensitivity of IP73 score were 77.9% and 81.9%, respectively. The IP73 score offers a novel, simple and noninvasive method of assessing CSPH in patients with compensated cirrhosis. A cut-off value of the IP73 score at 0 can distinguish patients with or without CSPH.

Abstract
AIM To assess the correlation and agreement between hepatic venous pressure gradient (HVPG) and portal pressure gradient (PPG) in patients with autoimmune liver diseases (ALD) and portal hypertension, and to investigate the extent to which hepatic vein collateralization affects the accuracy of this assessment. METHODS Ninety-eight patients with ALD between 2017 and 2021 who underwent transjugular intrahepatic portosystemic shunt with conventional and innovative 15 mL pressurized contrast were selected to measure wedged hepatic venous pressure (WHVP) and portal venous pressure and to calculate the HVPG and PPG. Pearson's correlation was used for correlation analysis between the two groups. Bland-Altman plots were plotted to estimate the agreement between paired pressures. RESULTS The r values of PPG and HVPG in the early, middle, late, and portal venous visualization were 0.404, 0.789, 0.807, and 0.830, respectively, and the R2 values were 0.163, 0.622, 0.651, and 0.690, respectively. The p value for the r and R2 values in the early group was 0.015, and the p values in the remaining groups were less than 0.001. Bland-Altman plots showed that patients in the portal venous visualization group had the narrowest 95% limits of agreement. The mean value of the difference was close to the zero-scale line. CONCLUSIONS In patients with ALD, the correlation between the HVPG and PPG was good, and the later the collateral development, the better the correlation. Hepatic vein collateral was an essential factor in underestimating WHVP and HVPG, and the earlier the collateral appeared, the more obvious the underestimation.

Abstract
BACKGROUND Non-selective beta-blockers (NSBB) are widely used in the treatment of patients with cirrhosis. Only about 50% respond with a sufficient reduction in their hepatic venous pressure gradient (HVPG) and NSBB may induce detrimental cardiac and renal effects in the presence of severe decompensation. We aimed to assess the effects of NSBB on haemodynamics using magnetic resonance imaging (MRI) and to assess if these haemodynamic changes were related to the disease severity and HVPG response. METHOD A prospective cross-over study of 39 patients with cirrhosis. Patients underwent hepatic vein catheterization and MRI with assessments of HVPG, cardiac function, systemic and splanchnic haemodynamics before and after propranolol infusion. RESULTS Propranolol induced significant decreases in cardiac output (-12%) and blood flow of all vascular compartments, with the largest reductions seen in the azygos venous (-28%), portal venous (-21%), splenic (-19%) and superior mesenteric artery (-16%) blood flow. Renal artery blood flow fell by -5% in the total cohort, with a more pronounced reduction in patients without ascites than in those with ascites (-8% vs. -3%, p = .01). Twenty-four patients were NSBB responders. Their changes in HVPG after NSBB were not significantly associated with other haemodynamic changes. CONCLUSION The changes in cardiac, systemic and splanchnic haemodynamics did not differ between NSBB responders and non-responders. The effects of acute NSBB blockade on renal flow seem to depend on the severity of the hyperdynamic state, with the largest reduction in renal blood flow in compensated patients compared to decompensated patients with cirrhosis. However, future studies are needed to assess the effects of NSBB on haemodynamics and renal blood flow in patients with diuretic-resistant ascites.

Abstract
BACKGROUND & AIMS Removing the primary aetiological factor in decompensated cirrhosis may lead to a restoration of hepatic function. In this study, we investigated the clinical implications of recompensation and the subsequent survival in patients with decompensated alcohol-related cirrhosis. METHODS The rate of recompensation was evaluated in patients with decompensated alcohol-related cirrhosis and persistent alcohol abstinence undergoing a hepatic venous pressure gradient (HVPG) measurement. Recompensation was defined according to Baveno VII criteria as resolution of ascites and hepatic encephalopathy, absence of variceal bleeding and improvement in liver function. RESULTS Two hundred and four abstinent patients with decompensated alcohol-related cirrhosis (age: 57.2 [IQR:50.1-63.7] years; 75.0% male; median MELD: 15 [IQR:11-19]) and a median HVPG of 20 (IQR:18-24) mmHg were included. During a median follow-up of 24.4 (IQR:10.9-50.4) months, 37 patients (18.1%) achieved abstinence-induced recompensation. Lower baseline HVPG, lower Child-Pugh score, lower BMI, higher albumin and higher mean arterial pressure were linked to a higher probability of recompensation. After adjusting for age, disease severity, portal hypertension and systemic inflammation, achieving recompensation resulted in a significant and considerable reduction in liver-related mortality (adjusted HR: 0.091 [95% CI: 0.012-0.677]; p = .019). Only 13 patients (6.4%) developed hepatocellular carcinoma, with a tendency towards a lower risk upon recompensation (HR: 0.398 [95% CI: 0.084-1.878]; p = .245), yet this finding did not reach statistical significance and requires further investigation. CONCLUSIONS Alcohol abstinence led to recompensation in 18.1% of our cohort of HVPG-characterised patients with decompensated alcohol-related cirrhosis. Achieving hepatic recompensation resulted in a >90% risk reduction in liver-related mortality.

Abstract
BACKGROUND AND AIMS A reduction in hepatic venous pressure gradient (HVPG) is the most accurate marker for assessing the severity of portal hypertension and the effectiveness of intervention treatments. This study aimed to evaluate the prognostic potential of blood-based proteomic biomarkers in predicting HVPG response amongst cirrhotic patients with portal hypertension due to Hepatitis C virus (HCV) and had achieved sustained virologic response (SVR). METHODS The study comprised 59 patients from two cohorts. Patients underwent paired HVPG (pretreatment and after SVR), liver stiffness (LSM), and enhanced liver fibrosis scores (ELF) measurements, as well as proteomics-based profiling on serum samples using SomaScan® at baseline (BL) and after SVR (EOS). Machine learning with feature selection (Caret, Random Forest and RPART) methods were performed to determine the proteins capable of classifying HVPG responders. Model performance was evaluated using AUROC (pROC R package). RESULTS Patients were stratified by a change in HVPG (EOS vs. BL) into responders (greater than 20% decline in HVPG from BL, or <10 mmHg at EOS with >10 mmHg at BL) and non-responders. LSM and ELF decreased markedly after SVR but did not correlate with HVPG response. SomaScan (SomaLogic, Inc., Boulder, CO) analysis revealed a substantial shift in the peripheral proteome composition, reflected by 82 significantly differentially abundant proteins. Twelve proteins accurately distinguished responders from non-responders, with an AUROC of .86, sensitivity of 83%, specificity of 83%, accuracy of 83%, PPV of 83%, and NPV of 83%. CONCLUSIONS A combined non-invasive soluble protein signature was identified, capable of accurately predicting HVPG response in HCV liver cirrhosis patients after achieving SVR.

Abstract
BACKGROUND Baveno VI and VII criteria are used in patients with cirrhosis to rule out large size oesophageal varices (EV) and rule in/out clinically significant portal hypertension (CSPH). AIM To evaluate their diagnostic performance in these patients. METHODS We retrospectively included all patients with Child-Pugh A cirrhosis and HCC who had endoscopy, liver stiffness measurement (LSM) and platelet count within 6 months. They were classified according to the BCLC stage. Favourable Baveno VI criteria were defined by LSM < 20 kPa and platelets > 150 G/L (to rule out large EV), favourable Baveno VII criteria if LSM ≤ 15 kPa and platelets ≥ 150 G/L (to rule out CSPH, which was defined by a HVPG ≥ 10 mm Hg. RESULTS We included 185 patients; 46% were BCLC-0/A, 28% BCLC-B and 26% BCLC-C. EV were present in 44% (23% large), and HVPG ≥ 10 mm Hg in 42% (mean 8 mm Hg). In patients with favourable Baveno VI criteria, 8% of the whole cohort (Se 93%, NPV 92%), 11% of BCLC-0-A (Se 89%, NPV 89%) and 10.0% of BCLC-C patients (Se 91%, NPV 90%) had large EV. Among patients with HVPG < 10 mm Hg, 6% had large EV and 17% small. CSPH was present in 23% of patients with favourable Baveno VII criteria among the whole cohort, and in 25% of those with BCLC-0/A. The specificity of LSM ≥ 25 kPa to rule in CSPH was 48%. CONCLUSIONS Favourable Baveno VI criteria are not appropriate to rule out the presence of high-risk EV, or Baveno VII criteria to rule CSPH in/out in patients with HCC.

Abstract
BACKGROUND & AIMS In individuals with compensated advanced chronic liver disease (cACLD), the severity of portal hypertension (PH) determines the risk of decompensation. Invasive measurement of the hepatic venous pressure gradient (HVPG) is the diagnostic gold standard for PH. We evaluated the utility of machine learning models (MLMs) based on standard laboratory parameters to predict the severity of PH in individuals with cACLD. METHODS A detailed laboratory workup of individuals with cACLD recruited from the Vienna cohort (NCT03267615) was utilised to predict clinically significant portal hypertension (CSPH, i.e., HVPG ≥10 mmHg) and severe PH (i.e., HVPG ≥16 mmHg). The MLMs were then evaluated in individual external datasets and optimised in the merged cohort. RESULTS Among 1,232 participants with cACLD, the prevalence of CSPH/severe PH was similar in the Vienna (n = 163, 67.4%/35.0%) and validation (n = 1,069, 70.3%/34.7%) cohorts. The MLMs were based on 3 (3P: platelet count, bilirubin, international normalised ratio) or 5 (5P: +cholinesterase, +gamma-glutamyl transferase, +activated partial thromboplastin time replacing international normalised ratio) laboratory parameters. The MLMs performed robustly in the Vienna cohort. 5P-MLM had the best AUCs for CSPH (0.813) and severe PH (0.887) and compared favourably to liver stiffness measurement (AUC: 0.808). Their performance in external validation datasets was heterogeneous (AUCs: 0.589-0.887). Training on the merged cohort optimised model performance for CSPH (AUCs for 3P and 5P: 0.775 and 0.789, respectively) and severe PH (0.737 and 0.828, respectively). CONCLUSIONS Internally trained MLMs reliably predicted PH severity in the Vienna cACLD cohort but exhibited heterogeneous results on external validation. The proposed 3P/5P online tool can reliably identify individuals with CSPH or severe PH, who are thus at risk of hepatic decompensation. IMPACT AND IMPLICATIONS We used machine learning models based on widely available laboratory parameters to develop a non-invasive model to predict the severity of portal hypertension in individuals with compensated cirrhosis, who currently require invasive measurement of hepatic venous pressure gradient. We validated our findings in a large multicentre cohort of individuals with advanced chronic liver disease (cACLD) of any cause. Finally, we provide a readily available online calculator, based on 3 (platelet count, bilirubin, international normalised ratio) or 5 (platelet count, bilirubin, activated partial thromboplastin time, gamma-glutamyltransferase, choline-esterase) widely available laboratory parameters, that clinicians can use to predict the likelihood of their patients with cACLD having clinically significant or severe portal hypertension.

Abstract
Background: Wedge hepatic vein pressure (WHVP) accurately estimates the portal pressure (PP) in chronic sinusoidal portal hypertension patients. Whether this applies to patients with acute portal hypertension due to hepatic sinusoidal obstruction syndrome (HSOS) is unclear. Our aim was to assess the agreement between WHVP and PP in patients with HSOS by comparing them to decompensated cirrhosis patients. Methods: From December 2013 to December 2021, patients with pyrrolidine alkaloid-induced HSOS (PA-HSOS) receiving hepatic venous pressure gradient (HVPG) measurement and transjugular intrahepatic portosystem shunt (TIPS) were retrospectively collected and matched with those of patients with virus- or alcohol-related cirrhosis as a cirrhosis group. Pearson’s correlation (R), intraclass correlation coefficient (ICC), scatter plots, and the Bland−Altman method were performed for agreement evaluation. Results: A total of 64 patients were analyzed (30 PA-HSOS and 34 cirrhosis groups). The correlation between WHVP and PP was moderate in the PA-HSOS group (R: 0.58, p = 0.001; ICC: 0.68, p = 0.002) but good in the cirrhosis group (R: 0.81, p < 0.001; ICC: 0.90, p < 0.001). The percentage of patients with inconsistent WHVP and PP in the two groups was 13 (43.3%) and 15 (26.5%) (p = 0.156), respectively, and an overestimation of PP was more common in the PA-HSOS group (33.3% vs. 2.9%, p = 0.004). HVPG and portal pressure gradient (PPG) consistency was poor in both groups (R: 0.51 vs. 0.26; ICC: 0.65 vs. 0.41; p < 0.05). Conclusions: WHVP in patients with PA-HSOS did not estimate PP as accurately as in patients with virus- or alcohol-related cirrhosis, which was mainly due to PP overestimation.

Abstract
BACKGROUND & AIMS Non-invasive tests (NITs) for clinically significant portal hypertension (CSPH; hepatic venous pressure gradient [HVPG] ≥10 mmHg) have predominantly been studied in patients with active HCV infection. Investigations after HCV cure are limited and have yielded conflicting results. We conducted a pooled analysis to determine the diagnostic/prognostic utility of liver stiffness measurement (LSM)/platelet count (PLT) in this setting. METHODS A total of 418 patients with pre-treatment HVPG ≥6 mmHg who achieved sustained virological response (SVR) and underwent post-treatment HVPG measurement were assessed, of whom 324 (HVPG/NIT-cohort) also had paired data on pre-/post-treatment LSM/PLT. The derived LSM/PLT criteria were then validated against the direct endpoint decompensation in 755 patients with compensated advanced chronic liver disease (cACLD) with SVR (cACLD-validation-cohort). RESULTS HVPG/NIT-cohort: Among patients with cACLD, the pre-/post-treatment prevalence of CSPH was 80%/54%. The correlation between LSM/HVPG increased from pre- to post-treatment (r = 0.45 vs. 0.60), while that of PLT/HVPG remained unchanged. For given LSM/PLT values, HVPG tended to be lower post- vs. pre-treatment, indicating the need for dedicated algorithms. Combining post-treatment LSM/PLT yielded a high diagnostic accuracy for post-treatment CSPH in cACLD (AUC 0.884; 95% CI 0.843-0.926). Post-treatment LSM <12 kPa & PLT >150 G/L excluded CSPH (sensitivity: 99.2%), while LSM ≥25 kPa was highly specific for CSPH (93.6%). cACLD-validation-cohort: the 3-year decompensation risk was 0% in the 42.5% of patients who met the LSM <12 kPa & PLT >150 G/L criteria. In patients with post-treatment LSM ≥25 kPa (prevalence: 16.8%), the 3-year decompensation risk was 9.6%, while it was 1.3% in those meeting none of the above criteria (prevalence: 40.7%). CONCLUSIONS NITs can estimate the probability of CSPH after HCV cure and predict clinical outcomes. Patients with cACLD but LSM <12 kPa & PLT>150 G/L may be discharged from portal hypertension surveillance if no co-factors are present, while patients with LSM ≥25 kPa require surveillance/treatment. LAY SUMMARY Measurement of liver stiffness by a specific ultrasound device and platelet count (a simple blood test) are broadly used for the non-invasive diagnosis of increased blood pressure in the veins leading to the liver, which drives the development of complications in patients with advanced liver disease. The results of our pooled analysis refute previous concerns that these tests are less accurate after the cure of hepatitis C virus (HCV) infection. We have developed diagnostic criteria that facilitate personalized management after HCV cure and allow for a de-escalation of care in a high proportion of patients, thereby decreasing disease burden.

Abstract
INTRODUCTION Advanced chronic liver disease is considered a reversible condition after removal of the primary aetiological factor. This has led to a paradigm shift in which portal hypertension (PH) is a reversible complication of cirrhosis. The pharmacologic management of PH is centered on finding targets to modify the natural history of cirrhosis and PH. AREAS COVERED This paper offers an overview of the use of pharmacological strategies in early clinical development that modify PH. Papers included were selected from searching clinical trials sites and PubMed from the last 10 years. EXPERT OPINION A paradigm shift has generated a new concept of PH in cirrhosis as a reversible complication of a potentially curable disease. Decreasing portal pressure to prevent decompensation and further complications of cirrhosis that may lead liver transplantation or death is a goal. Therapeutic strategies also aspire achieve total or partial regression of fibrosis thus eliminating the need for treatment or screening of PH.

Abstract
Portal hypertension (PH) in liver cirrhosis leads to increased gut permeability and the translocation of bacteria across the gut-liver axis. Microbial DNA has recently been detected in different blood compartments; however, this phenomenon has not been thoroughly analyzed in PH. This study aimed to explore circulating bacterial DNA signatures, inflammatory cytokines, and gut permeability markers in different blood compartments (peripheral and hepatic veins) of patients with cirrhosis and PH. The 16S rRNA blood microbiome profiles were determined in 58 patients with liver cirrhosis and 46 control patients. Taxonomic differences were analyzed in relation to PH, liver function, inflammatory cytokines, and gut permeability markers. Circulating plasma microbiome profiles in patients with cirrhosis were distinct from those of the controls and were characterized by enrichment of Comamonas, Cnuella, Dialister, Escherichia/Shigella, and Prevotella and the depletion of Bradyrhizobium, Curvibacter, Diaphorobacter, Pseudarcicella, and Pseudomonas. Comparison of peripheral and hepatic vein blood compartments of patients with cirrhosis did not reveal differentially abundant taxa. Enrichment of the genera Bacteroides, Escherichia/Shigella, and Prevotella was associated with severe PH (SPH) in both blood compartments; however, circulating microbiome profiles could not predict PH severity. Escherichia/Shigella and Prevotella abundance was correlated with IL-8 levels in the hepatic vein. In conclusion, we demonstrated a distinct circulating blood microbiome profile in patients with cirrhosis, showing that specific bacterial genera in blood are marginally associated with SPH, Model for End-Stage Liver Disease score, and inflammation biomarkers; however, circulating microbial composition failed to predict PH severity.

Abstract
OBJECTIVE The hepatic venous pressure gradient (HVPG) plays an important role in the treatment and prognosis of patients with cirrhosis. Our study aimed to develop and validate a nomogram for an HVPG >12 mmHg. METHODS A retrospective study was performed to create a nomogram for an HVPG >12 mmHg in a training cohort that was validated in another cohort. The discriminatory ability and calibration of the nomogram were tested using the C-statistic, area under the receiver operating characteristic curve (AUROC) and calibration plots. RESULTS The nomogram was based on portosystemic shunts identified on computed tomography images, the etiology of cirrhosis and the Child-Pugh grade. These parameters were significantly associated with an HVPG >12 mmHg (P < 0.05 for both the training and validation cohorts). In the training cohort, the model showed good discrimination (C-statistic, AUROC, and R2 of 0.71, 0.71 and 0.13, respectively) and good calibration. The total cutoff value was 112 and the sensitivity and specificity were 57.1% and 77.6%, respectively. The application of the nomogram in the validation cohort still yielded good discrimination (C-statistic 0.75 [95% confidence interval 0.61-0.89], AUROC 0.75, and R2 0.16) and good calibration. CONCLUSIONS This nomogram is a convenient tool for predicting an HVPG >12 mmHg in patients with cirrhosis and can help clinicians quickly identify patients with decompensated cirrhosis.

Abstract
BACKGROUND AND AIM Measuring the hepatic venous pressure gradient (HVPG) is an established technique to detect increased portal pressure and predict the presence of esophageal varices (EVs); however, the risk of the test is greater than the information it provides. This study aimed to clarify the usefulness of virtual touch tissue quantification (VTQ), which assesses liver stiffness, in predicting the presence of EVs in patients with liver cirrhosis by comparing it with HVPG. METHODS Two hundred seventeen patients with liver cirrhosis underwent VTQ, HVPG measurement, and upper endoscopy. Patients were divided into three groups: group V, hepatitis C virus liver cirrhosis (n = 40); group A, alcoholic liver cirrhosis (n = 116); and group N, other liver cirrhosis (n = 61). In each group, we performed linear regression analysis of VTQ and HVPG data. The accuracy of VTQ and HVPG measurement in predicting the presence of EVs and high-risk EVs (EV category F2 and F3) was assessed by area under the receiver operating characteristic curve (AUROC). RESULTS VTQ was significantly correlated with the HVPG in the whole patients and in each group, and both VTQ and HVPG values were significantly higher in patients with EVs and high-risk EVs than in those without. The AUROC for the presence of EVs for VTQ was 0.76 in the whole sample, 0.76 in group V, 0.79 in group A, and 0.67 in group N; and for HVPG, 0.92, 0.94, 0.93, and 0.88, respectively. For VTQ, the AUROC for the presence of high-risk EVs was 0.78 in the whole sample, 0.78 in group V, 0.73 in group A, and 0.73 in group N; and for HVPG, it was 0.85, 0.82, 0.85, and 0.82, respectively. CONCLUSION VTQ was reliable at predicting the presence of EVs and high-risk EVs. Therefore, we propose that VTQ is a useful, noninvasive tool for predicting the presence of EVs in daily medical care.

Abstract
BACKGROUND In patients with acute liver injury caused by hepatic veno-occlusive disease (HVOD), molecular adsorbent recirculation system (MARS) may be used to improve liver function in conjunction with transjugular intrahepatic portosystemic shunt (TIPS) to reduce portal hypertension. METHODS Twelve patients were admitted to our hospital following treatment for HVOD for 10 to 21 days at other hospitals. All patients were treated with a combination of MARS and TIPS, and they were evaluated clinically including liver function tests. RESULTS After the initial treatment with MARS, liver function improved significantly in all patients. TIPS placement decreased the hepatic venous pressure gradient (HVPG) to 10.17 ± 2.26 mmHg from a pre-TIPS HVPG of 23.58 ± 9.43 mmHg. The outcomes of combination treatment with MARS and TIPS in 12 patients with HVOD were as follows: 1) improvement of various clinical and biological parameters leading to full recovery in 1 year in 6 patients; 2) full recovery following liver transplantation for acute liver failure in three patients; and 3) three patients died due to hepatic failure after TIPS placement. CONCLUSION The combination of MARS and TIPS creation is promising as a potential treatment for acute HVOD, and it showed an improvement in overall survival.

Abstract
AIM Patients who undergo the Fontan procedure for complex congenital heart disease are prone to liver cirrhosis. Liver stiffness (LS) reflects liver fibrosis stage in patients with chronic viral hepatitis; however, its accuracy in predicting liver fibrosis stage in Fontan patients is controversial. We aimed to clarify the correlation between LS and liver fibrosis stage in Fontan patients. METHODS Fifty-eight Fontan patients were prospectively measured for LS with transient elastography. We undertook liver biopsy, cardiac catheterization, and laboratory tests in 22 of these patients (median age, 14.7 years; range, 9.9-32.1 years) with LS > 11.0 kPa (median, 19.2 kPa; range, 12.2-39.8 kPa); these elevated LS values suggest liver cirrhosis. RESULTS Histologically, all patients showed mild-to-severe portal and sinusoidal fibrosis but no cirrhosis. Statistically, LS did not predict histological liver fibrosis scores (p = 0.175). Liver stiffness was not correlated with central venous pressure (p = 0.456) or with the hepatic venous pressure gradient (HVPG; p = 0.062), although the p value for HVPG was only slightly above the threshold for significance. CONCLUSIONS Fontan patients are prone to developing both portal and sinusoidal fibrosis. Liver stiffness could be influenced by HVPG, and using the conventional cut-off values for LS overestimates and overtreats liver fibrosis in these patients.

Abstract
AIM Hepatic venous pressure gradient (HVPG) measurement is a gold standard for the diagnosis of portal hypertension but can be invasive and difficult to conduct. Per-rectal portal scintigraphy (PRPS) can estimate portal haemodynamics noninvasively. However, no report to date has examined the association between HVPG and PRPS in patients with chronic liver disease, including cirrhosis. METHODS This single-centre study included a total of 21 patients with chronic liver disease who underwent HVPG measurement and PRPS. For PRPS, the transit times from injection of the radiotracer to its inflow into the liver (TTL) and heart (TTH) were set and the time difference between TTL and TTH (TDLH) was calculated, while the shunt index (SI) was measured. RESULTS Cirrhosis was observed in 18 cases (86%), and the median HVPG was 13 mmHg. HVPG (p = 0.028), TTL (p = 0.018), TDLH (p = 0.003) and SI (p = 0.033) were higher in patients with oesophageal varices (EV). Considering the diagnostic ability for EV, the area under the curve was 0.88 for TDLH and 0.80 for HVPG. TDLH was significantly correlated with the risk of EV rupture (p = 0.004). CONCLUSION Patients with chronic liver disease should undergo upper gastrointestinal endoscopy when the TDLH is high.

Abstract
BACKGROUND AND AIMS Portal hypertension (PH) and sarcopenia are common in patients with advanced chronic liver disease (ACLD). However, the interaction between PH and sarcopenia and their specific and independent impact on prognosis and mortality has yet to be systematically investigated in patients with ACLD. METHODS Consecutive patients with ACLD and hepatic venous pressure gradient (HVPG) ≥10 mm Hg with available CT/MRI imaging were included. Sarcopenia was defined by transversal psoas muscle thickness (TPMT) at <12 mm/m in men and <8 mm/m in women at the level of the third lumbar vertebrae. Hepatic decompensation and mortality was recorded during follow-up. RESULTS Among 203 patients (68% male, age: 55 ± 11, model for end-stage liver disease [MELD]: 12 [9-15]), sarcopenia was observed in 77 (37.9%) and HVPG was ≥20 mm Hg in 98 (48.3%). There was no correlation between TPMT and HVPG (r = .031, P = .66), median HVPG was not different between patients with vs without sarcopenia (P = .211). Sarcopenia was significantly associated with first/further decompensation both in compensated (SHR: 3.05, P = .041) and in decompensated patients (SHR: 1.86, P = .021). Furthermore, sarcopenia (SARC) was a significant predictor of mortality irrespective of HVPG (HVPG < 20-SARC: SHR: 2.25, P = .021; HVPG ≥ 20-SARC: SHR: 3.33, P = .001). On multivariate analysis adjusted for age, HVPG and MELD, sarcopenia was an independent risk factor for mortality (aHR: 1.99, 95% confidence interval: 1.2-3.3, P = .007). CONCLUSION Sarcopenia has a major impact on clinical outcomes both in compensated and in decompensated ACLD patients. The presence of sarcopenia doubled the risk for mortality independently from the severity of PH.

Abstract
Portal hypertension is the main driver of complications in patients with advanced chronic liver disease (ACLD) and is defined by values of hepatic venous pressure gradient measurement (HVPG) >5 mmHg. Values of HVPG ≥10 mmHg determine the presence of clinically significant portal hypertension (CSPH), the main predictor of the risk of variceal bleeding, hepatic decompensation, and mortality. However, its measurement is invasive and requires high expertise, so its routine use outside third level centers or clinical trials is limited. In the last decades, several non-invasive tests (NITs) have been developed and validated for the diagnosis of portal hypertension. Among these, liver (LSM) and spleen stiffness measurement (SSM) are the most promising tools available, as they have been proven accurate to predict CSPH, high-risk esophageal varices, decompensation, and mortality in patients with ACLD. In the last Baveno VI Consensus proceedings, LSM evaluation was recommended for the first time for diagnosis of CSPH (LSM >20-25 kPa) and the screening of patients with a low probability of having high-risk varices (LSM <20 kPa and platelet count >150.000/mm3). In this review, we aimed to summarize the growing evidence supporting the use of non-invasive tests for the evaluation of portal hypertension in patients with chronic liver disease.

Abstract
BACKGROUND/AIM Endothelin causes vasoconstriction via the endothelin-A receptor (ET-A) in the intrahepatic circulation in cirrhosis and its increase leads to portal hypertension. The aim of the study was to investigate the acute effect of a selective ET-A antagonist in patients with portal hypertension and cirrhosis. METHODS Proof-of-concept study with two different substudies: (a) local intrahepatic administration of the ET-A antagonist BQ 123 and (b) systemic oral administration of the ET-A antagonist Ambrisentan. Portal pressure was determined by hepatic venous pressure gradient (HVPG, both substudies) and hepatic arterial blood flow (HABF) by intra-arterial Doppler measurements (substudy 1) before and under the ET-A antagonist. Systemic haemodynamic parameters were measured in substudy 2. RESULTS Twelve patients (Child-Pugh [CP] B/C n = 7/5) were included in substudy 1 and 14 patients (CP A/B/C n = 4/6/4) in substudy 2. The relative decrease in HVPG was -12.5% (IQR: -40% to 0%; P = .05) in substudy 1 and -5.0% (IQR: -11.5% to 0%; P = .01) in substudy 2. Substudy 1 revealed higher decrease in HVPG in CP B patients. HABF increased significantly and patients without portal pressure decrease showed a higher increase of HABF. Substudy 2 showed a slight decrease in the mean arterial pressure without changes of other systemic haemodynamic parameters. CONCLUSION Administration of a selective ET-A antagonist decreases the portal pressure in cirrhotic patients. This decrease was higher in CP B patients and the non-responders showed a higher increase in hepatic arterial flow. Selective ET-A antagonists might be a future treatment option in patients with portal hypertension.

Abstract
BACKGROUND Portal vein velocity (PVV) has shown reasonable correlation with the presence of portal hypertension in patients with cirrhosis. This study aims to evaluate the value of PVV for diagnosing clinically significant portal hypertension (CSPH) and predicting the risk of variceal hemorrhage (VH) in patients with hepatitis B virus (HBV)-related cirrhosis. MATERIAL AND METHODS A cohort of 166 consecutive adult patients with HBV-related cirrhosis was recruited in this retrospective study from two high-volume liver centers in China between April 2015 and April 2017. The performance of PVV and other non-invasive parameters for diagnosing CSPH and predicting risk of VH were studied. RESULTS PVV demonstrated the best performance for diagnosing CSPH (defined as an HVPG ≥10 mmHg) in patients with HBV-related cirrhosis among the included noninvasive predictors with the area under the receiver operating characteristic curve (AUC), specificity, and sensitivity of 0.745, 50%, and 93.5%, respectively. Other noninvasive markers, including APRI, AAR, LS, FIB-4, and diameter of portal vein, did not show sufficient performance with the AUCs of 0.565, 0.560, 0.544, 0.529, and 0.474, respectively. With regard to predicting the risk of VH (defined as an HVPG ≥12 mmHg), PPV also exhibited a moderate performance with an AUC of 0.762, which was superior to that of the aforementioned markers. By using two cutoff values of PVV to rule-out (11.65 cm/s) and rule-in (20.20 cm/s) CSPH, 30 (33.7%) patients showed definite results categories, with 23 (76.7%) patients were well classified and 7 (23.3%) were misclassified. Fifty-nine (66.3%) patients were with indeterminate results. By using PVV values of 13.10 cm/s and 21.40 cm/s to rule-out and rule-in HVPG ≥ 12mmHg, 34 (38.2%) patients has definite results, among whom 26 (76.5%) were well classified and 8 (23.5%) were misclassified. And 55 (61.8%) patients required further evaluation. CONCLUSION PPV is not good enough to serve as a non-invasive parameter for identifying CSPH and predicting risk of VH in patients with HBV-related cirrhosis.

Abstract
BACKGROUND AND AIMS Hemodynamic response to pharmacotherapy improves survival in patients with cirrhosis post variceal bleeding, but long-term outcomes remain unexplored especially in this part of the world. We aimed to study the long-term impact of portal pressure reduction on liver-related outcomes after index variceal bleed. METHODS Patients with hepatic venous pressure gradient (HVPG) more than 12 mm Hg after index variceal bleed were given non-selective beta-blockers in combination with variceal band ligation. HVPG response was assessed after 4 weeks. Patients were followed up for rebleed events, survival, additional decompensation events and safety outcomes. Rebleed and other decompensations were compared using competing risks analysis, taking death as competing event, and survival was compared using Kaplan-Meier analysis. RESULTS Forty-eight patients (29 responders and 19 non-responders) were followed up for a median duration of 45 (24-56) months. Rebleeding rates at 1, 3 and 5 years were 10.3%, 20.7% and 20.7% in responders and 15.8%, 44.7% and 51.1% in non-responders, respectively (Gray's test, P = 0.044). Survival rates at 1, 3 and 5 years were 89.7%, 72.1% and 51.9% in responders and 89.5%, 44% and 37.7% in non-responders, respectively (log-rank test, P = 0.1). Both severity of liver disease (MELD score, multivariate sub-distributional hazards ratio: 1.166 [1.014-1.341], P = 0.030) and HVPG non-response (multivariate sub-distributional hazards ratio: 2.476 [1.87-7.030], P = 0.045) predicted rebleeding risk while survival was dependent only on severity of liver disease (MELD > 12, multivariate hazards ratio: 2.36 [1.04-5.38], P = 0.041). CONCLUSION Baseline severity of liver disease predicted survival and rebleed in these patients. Hemodynamic response, although associated with lower rebleeding rate, had limited impact on survival.

Abstract
AIMS AND BACKGROUND There is limited information on comparison of clinical outcomes with carvedilol for secondary prophylaxis following acute variceal bleed (AVB) when compared with propranolol. We report long-term clinical and safety outcomes of a randomised controlled trial comparing carvedilol with propranolol with respect to reduction in hepatic venous pressure gradient (HVPG) in patients after AVB. METHODS We conducted a post-hoc analysis of patients recruited in an open-label randomized controlled trial comparing carvedilol and propranolol following AVB, and estimated long-term rates of rebleed, survival, additional decompensation events and safety outcomes. Rebleed and other decompensations were compared using competing risks analysis, taking death as competing event, and survival was compared using Kaplan-Meier analysis. RESULTS Forty-eight patients (25 taking carvedilol; 23 propranolol) were followed up for 6 years from randomization. More number of patients on carvedilol had HVPG response when compared with those taking propranolol (72%- carvedilol versus 47.8% propranolol, p = 0.047). Comparable 1-year and 3-year rates of rebleed (16.0% and 24.0% for carvedilol versus 8.9% and 36.7% for propranolol; p = 0.457) and survival (94.7% and 89.0% for carvedilol versus 100.0% and 79.8% for propranolol; p = 0.76) were obtained. New/worsening ascites was more common in those receiving propranolol (69.5% vs 40%; p = 0.04). Other clinical decompensations and complications of liver disease occurred at comparable rates between two groups. Drug-related adverse-events were similar in both groups. CONCLUSION Despite higher degree of HVPG response, long-term clinical, survival and safety outcomes in carvedilol are similar to those of propranolol in patients with decompensated cirrhosis after index variceal bleed with the exception of ascites that developed less frequently in patients with carvedilol.

Abstract
AIMS The efficacy of somatostatin in altering splanchnic hemodynamics in cirrhotic portal hypertension is still controversial. We aimed to establish the dynamic effect of somatostatin on portal pressure in cirrhotic patients and compared its effect with Partial Splenic Embolization (PSE). METHODS Eighteen patients with cirrhotic portal hypertension were prospectively recruited. The wedged hepatic venous pressure (WHVP) and free hepatic venous pressure (FHVP) were repeatedly measured at baseline, 1-, 5-, 10- and 20-min after initiating somatostatin infusion. After somatostatin infusion cessation and washout, WHVP and FHVP were measured before and after PSE. The change in all the variables between time points was analyzed. RESULTS Decreased hepatic venous pressure gradient (HVPG) 5-min after initiation of infusion was identified compared with baseline level (19.6%; p-value: .042), which was achieved through elevated FHVP (37.5%; p-value: 9.26e - 04). There was no significant decrease in WHVP at any time point during somatostatin infusion. The HVPG (17.4%; p-value: 1.27e - 04) and WHVP (10.4%; p-value: 3.00e - 03) post-PSE significantly decreased compared to the washout level. No significant distribution differences in the number of patients with HVPG decrease by a percentage relative to the baseline level were identified between the 5-min time point and post-PSE. CONCLUSION Our study indicates that somatostatin administration does not decrease WHVP within 20 min at clinically recommended doses. While somatostatin did decrease HVPG, this effect was achieved through increased FHVP, providing a possible explanation for its unclear efficacy. In contrast, PSE decreases both the WHVP and the HVPG.

Abstract
BACKGROUND AND AIMS The enhanced liver fibrosis (ELF) score comprises serum markers of fibrogenesis and matrix remodelling and was developed to detect liver fibrosis, however, it may also be useful for the non-invasive detection of portal hypertension (PHT). METHODS ELF score and its single components (TIMP1/PIIINP/HA) were analysed in 201 patients with advanced chronic liver disease (ACLD; ie hepatic venous pressure gradient (HVPG) ≥6 mm Hg). Patients with pre-/post-hepatic PHT, hepatocellular carcinoma beyond Milan criteria, and history of TIPS implantation or liver transplantation were excluded. RESULTS ELF and its single components correlated with HVPG in the overall cohort: ELF: r = .443, TIMP1: r = .368, PIIINP:r = .332, and HA:r = .419 (all P < .001). The strength of the correlation between ELF and HVPG decreased in higher HVPG strata: 6-9 mm Hg:r = .569(P = .004), 10-19 mm Hg:r = .304 (P = .001) and ≥20 mm Hg:r = -.023(P = .853). Area under the receiver operating characteristics (AUROC) of ELF score to detect clinically significant PHT (CSPH; HVPG ≥ 10 mm Hg) was 0.833. Importantly, HA alone yielded an AUROC of 0.828. Detection of CSPH in strictly compensated ACLD (cACLD) patients was less accurate: AUROC: 0.759 (P < .001). CSPH was ruled-in by ELF ≥ 11.1 with a PPV of 98% (sensitivity: 61%/specificity: 92%/NPV:24%), but CSPH could not be ruled-out. ELF score had a low AUROC of 0.677 (0.60-0.75; P < .001) for the diagnosis of high-risk PHT (HRPH; HVPG ≥ 20mm Hg) and, thus, HRPH could not be ruled-in by ELF. However, ELF < 10.1 ruled-out HRPH with a NPV of 95% (sensitivity: 97%/specificity: 26%/PPV: 39%). CONCLUSION The ELF score correlates with HVPG at values <20 mm Hg. An ELF ≥ 11.1 identifies patients with a high probability of CSPH, while an ELF < 10.1 may be used to rule-out HRPH.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a substantial and growing problem worldwide and has become the second most common indication for liver transplantation as it may progress to cirrhosis and develop complications from portal hypertension primarily caused by advanced fibrosis and erratic tissue remodeling. However, elevated portal venous pressure has also been detected in experimental models of fatty liver and in human NAFLD when fibrosis is far less advanced and cirrhosis is absent. Early increases in intrahepatic vascular resistance may contribute to the progression of liver disease. Specific pathophenotypes linked to the development of portal hypertension in NAFLD include hepatocellular lipid accumulation and ballooning injury, capillarization of liver sinusoidal endothelial cells, enhanced contractility of hepatic stellate cells, activation of Kupffer cells and pro-inflammatory pathways, adhesion and entrapment of recruited leukocytes, microthrombosis, angiogenesis and perisinusoidal fibrosis. These pathological events are amplified in NAFLD by concomitant visceral obesity, insulin resistance, type 2 diabetes and dysbiosis, promoting aberrant interactions with adipose tissue, skeletal muscle and gut microbiota. Measurement of the hepatic venous pressure gradient by retrograde insertion of a balloon-tipped central vein catheter is the current reference method for predicting outcomes of cirrhosis associated with clinically significant portal hypertension and guiding interventions. This invasive technique is rarely considered in the absence of cirrhosis where currently available clinical, imaging and laboratory correlates of portal hypertension may not reflect early changes in liver hemodynamics. Availability of less invasive but sufficiently sensitive methods for the assessment of portal venous pressure in NAFLD remains therefore an unmet need. Recent efforts to develop new biomarkers and endoscopy-based approaches such as endoscopic ultrasound-guided measurement of portal pressure gradient may help achieve this goal. In addition, cellular and molecular targets are being identified to guide emerging therapies in the prevention and management of portal hypertension.

Abstract
INTRODUCTION Portal hypertension (PH) is a severe disease with a poor outcome. Hepatic venous pressure gradient (HVPG), the current gold standard to detect PH, is available only in few hospitals due to its invasiveness and technical difficulty. This study aimed to establish and assess a novel model to calculate HVPG based on biofluid mechanics. METHODS AND ANALYSIS This is a prospective, randomised, non-controlled, multicentre trial. A total of 248 patients will be recruited in this study, and each patient will undergo CT, blood tests, Doppler ultrasound and HVPG measurement. The study consists of two independent and consecutive cohorts: original cohort (124 patients) and validation cohort (124 patients). The researchers will establish and improve the HVPG using biofluid mechanics (HVPGBFM)model in the original cohort and assess the model in the validation cohort. ETHICS AND DISSEMINATION The study was approved by the Scientific Research Projects Approval Determination of Independent Ethics Committee of Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine (approval number 2017-430 T326). Study findings will be disseminated through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER NCT03470389.

Abstract
OBJECTIVE To observe the immediate and mid-term effects of partial spleen embolization (PSE) in reducing hepatic venous pressure gradient (HVPG) in patients with cirrhotic esophagogastric varices. METHODS Patients diagnosed with cirrhosis and esophagogastric varices in our hospital between July 2016 and March 2018 were consecutively selected. Forty-three patients were selected based on the eligibility criteria to undergo PSE. The change in HVPG 5 minutes before and after embolization, was used to determine the immediate effect of PSE on HVPG reduction. HVPG was retested after 6 months to observe the change in the antihypertensive effect along with time. RESULTS Forty-three patients successfully underwent PSE and HVPG measurements. The HVPG was 17.7 ± 3.9 mmHg and 13.9 ± 3.1 mmHg before and after PSE, respectively, showing a significant decrease (21.5%, P < .05). Among them, 18 cases were retested for HVPG at 6 months after PSE, and the results showed significant differences in the HVPG levels before, immediately and 6 months after PSE. Compared with preoperative PSE, HVPG was decreased by 22.9% and 17.7% (P < 0.05) immediately and at 6 months after operation, respectively. There was no significant change at 6 months after PSE when compared with immediate postoperative PSE. No serious complications were observed in patients during their postoperative hospital stay. CONCLUSION PSE immediately reduced the portal pressure, and HVPG remained stable at 6 months after surgery. PSE is considered as a safe and easy to implement method, and is expected to be one of the treatments for reducing the portal pressure.

Abstract
Idiopathic non-cirrhotic portal hypertension is a rare diagnosis caused by an
unknown etiology with elevated intrahepatic portal pressures in the absence of
underlying liver disease. We present a unique case of a 57-year-old male with a
left ventricular assist device and preserved right ventricular function that was
found to have an elevated hepatic venous pressure gradient and sequelae of
portal hypertension without underlying liver disease. There is limited treatment
available as management is primarily aimed toward preventing complications of
the disease. This case highlights the need for further investigative research of
this disease entity and its pathogenesis.

Abstract
Background & Aims Refractory ascites is the main reason for the implantation of a transjugular intrahepatic portosystemic shunt (TIPS) in liver cirrhosis, but ascites control by TIPS fails in a relevant proportion of cases. Here, we investigated whether routine parameters pre-TIPS can predict persistent ascites after TIPS implantation and whether persistent ascites predicts long-term clinical outcome. Methods A detailed retrospective analysis of 128 patients receiving expanded polytetrafluoroethylene-covered stents for the treatment of refractory ascites was performed. Persistent ascites post-TIPS was defined as the prolonged need for paracentesis >3 months after TIPS. The influence of demographics, laboratory results, pre-TIPS heart and liver ultrasound results, and invasive hemodynamic parameters on persistent ascites was evaluated by univariable and multivariable logistic regression. Predictors of the composite endpoint liver transplantation/death were analyzed using a multivariable Cox regression. Results Ascites control post-TIPS was achieved in 95/128 patients (74%), whereas ascites remained persistent in 33/128 cases (26%). On multivariable analysis, a lower paracentesis frequency pre-TIPS (odds ratio 1.672; 95% CI 1.253–2.355) and lower baseline creatinine levels (odds ratio 2.640; CI 1.201–6.607) were associated with ascites control. Patients with persistent ascites post-TIPS had and impaired transplant-free survival (median 10.0 vs. 25.8 months), for which persistent ascites was the only independent predictor (hazard ratio 5.654; CI 3.019–10.59). Conclusion TIPS-placement in patients with lower paracentesis frequency and creatinine levels is associated with superior ascites control. Thus, TIPS implantation should be considered in moderate decompensation and not as a last resort. Persistent ascites post-TIPS seems to be the only predictor of liver transplantation and death. Lay summary The insertion of a transjugular intrahepatic portosystemic shunt (TIPS) in patients with refractory ascites should be considered in patients with moderate decompensation and not as a last resort, as lower paracentesis frequency and creatinine levels pre-TIPS are associated with superior ascites control. In turn, failure to control ascites seems to be the only predictor of liver transplantation and death. Ascites control post-TIPS is superior if the TIPS is placed at lower paracentesis frequency and creatinine levels. Transplant-free survival is decreased in patients with a failed ascites control post-TIPS. TIPS-placement should be considered “early” in ascitic decompensation. Close monitoring and prioritized organ allocation should be considered in patients with failed ascites control post-TIPS.

Abstract
Veno-occlusive-disease (VOD), known also as sinusoidal-obstruction-syndrome (SOS), is one of the main complications of haematopoietic stem cell transplantation and is related to the treatment with pyrrolizidine alkaloids or other toxic agents (chemotherapy for liver-metastasis). Clinical diagnosis using the recent criteria from the European Society for Blood and Marrow Transplantation, is the reference for VOD/SOS diagnosis. However, increasing evidence suggests the emerging role of several imaging methods that could help the clinician in VOD/SOS assessment. Areas covered: This review evaluates the current literature on the various imaging techniques used in VOD/SOS diagnosis in several clinical scenarios. Literature searches were performed using several keywords on MEDLINE/Ovid/In-Process/Cochrane Library/EMBASE and PubMed up to July 2018. Expert commentary: Hepatic-gradient-measurement (HVPG) and contextual transjugular-liver-biopsy are invasive and should always be considered in unclear cases. The main studies revolve around ultrasound with Doppler evaluation, identifying numerous findings suggestive of VOD/SOS. However, their accuracy and validation are still suboptimal and controversial. CT-Scan and MRI have shown encouraging data in other contexts in which VOD/SOS can develop, but studies on the post-HSCT patient are lacking. Elastography techniques measuring liver stiffness (LSM) represent the most recent and promising approach for an accurate and early diagnosis of VOD/SOS. In our view, a multidisciplinary approach to the VOD/SOS diagnosis should be highly encouraged.

Abstract
PURPOSE OF REVIEW To provide an overview of recent pharmacological treatments for portal hypertension evaluated in early clinical trials, with particular emphasis on the pathophysiological basis of their use. RECENT FINDINGS In patients with compensated cirrhosis, even small decreases in portal pressure (as small as 1 mmHg) are associated with a lower probability of decompensation. In patients with decompensated cirrhosis, portal pressure "response" to non-selective beta-blocker (NSBB) therapy is associated with a lower mortality. When present, significant portal hypertension persists even after elimination of the etiology of cirrhosis and this justifies the continued development of new drugs that target portal hypertension. SUMMARY Over several decades we have gained great depth in the understanding of portal hypertension, its mechanisms and complications. NSBBs, which act by reducing portal venous inflow (an extrahepatic target), are effective in reducing portal pressure and have been the mainstay of therapy for portal hypertension in the last 35 years -being effective in preventing decompensation and variceal hemorrhage. However, because not all patients will have a sufficient response to NSBB and some may be intolerant to NSBB, alternative drugs or drugs that will augment the effect of NSBB on portal pressure are being tested in pre-clinical and early-clinical trials. Many of these drugs target more than one of the intrahepatic or extrahepatic mechanisms implicated in the pathogenesis of portal hypertension in cirrhosis. Out of these proposed therapies, statins have emerged as the most promising new pharmacological therapy for the treatment of portal hypertension.

Abstract
Liver stiffness (LS) as measured by transient elastography is increasingly used to noninvasively assess liver fibrosis. However, LS is efficiently modulated by confounders like arterial and portal pressure (PP). We here study the effect of acute hemodynamic changes on LS (measured by µFibroscan) in a rodent model of cirrhosis in response to pharmacological modulation of PP by losartan, nitric oxide donors, and propranolol. Additionally, changes of LS and the hepatic venous pressure gradient (HVPG) under propranolol therapy were assessed with regard to clinical outcomes in a human cohort of n = 38 cirrhotic patients. In the animal model, cirrhosis induction resulted in a significant increase of LS and PP. After losartan or NO application, a LS decrease of 25% was strongly correlated with a concomitant decrease of mean arterial pressure (MAP) and PP. In contrast, acute propranolol administration decreased heart rate but not MAP resulting in stable LS. In the human cohort, most patients ( n = 25, 66%) showed a LS decrease after propranolol treatment initiation which significantly correlated to HVPG ( r = 0.518, P < 0.01) but was not accompanied by statistically significant changes in transaminases or model of end-stage liver disease (MELD). On multivariate analysis, patients with decreasing LS on propranolol had a decreased risk for experiencing a transplantation or death than patients with increasing LS irrespective of HVPG. In conclusion, LS changes after pharmacological interventions are influenced by hemodynamic effects on arterial and portal pressure. In humans, a LS decrease may be predictive of improved outcome irrespective of MELD scores and may serve as an additional follow-up tool in the future. NEW & NOTEWORTHY Liver stiffness (LS) is efficiently modulated by changes in portal venous and systemic pressures in an animal model of liver cirrhosis irrespective of baseline LS and portal pressure values. In humans, most patients show a decrease in LS after propranolol treatment initiation without statistically significant changes in transaminases or model of end-stage liver disease (MELD) scores. A decrease in LS may be associated with improved outcome and thus another valuable tool in the follow-up of patients after propranolol treatment initiation.

The development of portal hypertension in a patient with cirrhosis portends a poor prognosis. Untreated or progressive portal hypertension has serious clinical outcomes, which are often fatal. It is important to recognize portal hypertension early to delay progression and to treat complications of portal hypertension as they arise. This review will focus on the clinical assessment and management of portal hypertension.

Abstract
Hepatic venous pressure gradient (HVPG) measurement provides independent prognostic value in patients with cirrhosis, and the prognostic and predictive role of HVPG in hepatocellular carcinoma (HCC) also has been explored. The management of HCC is limited to the European Association for the Study of the Liver (EASL) and American Association for the Study of Liver Diseases (AASLD) guidelines that consider that HVPG≥10 mmHg to be a contraindication for hepatic resection (HR), otherwise other treatment modalities are recommended. Current studies show that a raised HVPG diagnosed directly or indirectly leads to a negative prognosis of patients with HCC and cirrhosis, but HVPG greater than 10 mmHg should not be regarded as an absolute contraindication for HR. Selecting direct or surrogate measurement of HVPG is still under debate. Only several studies reported the impact of HVPG in negative prognosis of HCC patients after liver transplantation (LT) and the value of HVPG in the prediction of HCC development, which need to be further validated.

Abstract
OBJECTIVE To qualify shear wave elastography (SWE) as a biomarker for clinically significant portal hypertension (CSPH) beyond proof of concept, we aimed to accumulate and summarize the current evidence through systematic review and meta-analysis. MATERIALS AND METHODS A computerized literature search was performed to identify studies from MEDLINE and EMBASE up to February 9, 2017. Studies on the diagnostic performance of liver stiffness measurements using SWE for CSPH with hepatic venous pressure gradient (HVPG) as the reference standard were included. Various aspects of SWE were comprehensively assessed. The summary diagnostic performance of SWE for the diagnosis of CSPH and the summary correlation coefficient between liver stiffness measured using SWE and HVPG were evaluated through a meta-analysis. RESULTS Nine articles (including 746 patients) were retrieved. The diagnostic performance of SWE for the diagnosis of CSPH was fairly good, with a summary sensitivity of 85% (95% CI, 75-91%; I2 = 78.56%) and summary specificity of 85% (95% CI, 77-90%; I2 = 0%); the area under the ROC curve was 0.88 (95% CI, 0.85-0.91). The summary correlation coefficient between liver stiffness and HVPG measurements was 0.741 (95% CI, 0.658-0.825; I2 = 0%). These results support the value of SWE as a diagnostic biomarker for CSPH. However, there was significant heterogeneity in the imaging devices, protocols, liver stiffness measurement methods, and cutoff values used, which suggests that standardization is required. CONCLUSION The consistent evidence favoring SWE as a biomarker for CSPH should be considered in the biomarker qualification process and management of patients with CSPH.

Abstract
Portal hypertension is a predictor of liver-related clinical events and mortality in patients with hepatitis C and cirrhosis. The effect of interferon-free hepatitis C treatment on portal pressure is unknown. Fifty patients with Child-Pugh-Turcotte (CPT) A and B cirrhosis and portal hypertension (hepatic venous pressure gradient [HVPG] >6 mm Hg) were randomized to receive 48 weeks of open-label sofosbuvir plus ribavirin at Day 1 or after a 24-week observation period. The primary endpoint was sustained virologic response 12 weeks after therapy (SVR12) in patients who received ≥1 dose of treatment. Secondary endpoints included changes in HVPG, laboratory parameters, and MELD and CPT scores. A subset of patients was followed 48 weeks posttreatment to determine late changes in HVPG. SVR12 occurred in 72% of patients (33/46). In the 37 patients with paired HVPG measurements at baseline and the end of treatment, mean HVPG decreased by -1.0 (SD 3.97) mm Hg. Nine patients (24%) had ≥20% decreases in HVPG during treatment. Among 39 patients with pretreatment HVPG ≥12 mm Hg, 27 (69%) achieved SVR12. Four of the 33 (12%) patients with baseline HVPG ≥12 mm Hg had HVPG <12 mm Hg at the end of treatment. Of nine patients with pretreatment HVPG ≥12 mm Hg who achieved SVR12 and completed 48 weeks of follow-up, eight (89%) had a ≥20% reduction in HVPG, and three reduced their pressure to <12 mm Hg. Patients with chronic HCV and compensated or decompensated cirrhosis who achieve SVR can have clinically meaningful reductions in HVPG at long-term follow-up. (EudraCT 2012-002457-29).

Abstract
Portal hypertension is most frequently associated with cirrhosis and is a major driver for associated complications, such as variceal bleeding, ascites or hepatic encephalopathy. As such, clinically significant portal hypertension forms the prelude to decompensation and impacts significantly on the prognosis of patients with liver cirrhosis. At present, non-selective β-blockers, vasopressin analogues and somatostatin analogues are the mainstay of treatment but these strategies are far from satisfactory and only target splanchnic hyperemia. In contrast, safe and reliable strategies to reduce the increased intrahepatic resistance in cirrhotic patients still represent a pending issue. In recent years, several preclinical and clinical trials have focused on this latter component and other therapeutic avenues. In this review, we highlight novel data in this context and address potentially interesting therapeutic options for the future.

Abstract
BACKGROUND Portal hypertension is necessary for the development of most clinical complications of cirrhosis. We recently reported a novel, endoscopic ultrasound (EUS)-guided technique for direct portal pressure measurements using a digital pressure wire. AIMS The aims of this study were to (1) evaluate safety in an animal survival model and (2) compare direct portal vein (PV) versus transhepatic access of a first-order venule. MATERIALS AND METHODS Yorkshire pigs, weighing 40-55 kg. Procedures were performed under general anesthesia. PV was identified using a linear array echoendoscope and accessed with a 22-G fine needle aspiration needle preloaded with a digital pressure wire. Access was confirmed by portal venography. Mean digital pressure measurements were recorded over 30 seconds, and again after accessing a first-order portal venule in a transhepatic manner. Procedure times and video logs were maintained throughout. Animals were survived for 2 weeks. Repeat portal pressure measurements were performed before euthanasia and necropsy. RESULTS EUS-guided portal pressure measurements ranged from 3 to 11 mm Hg (mean 6.1) and were performed in a mean time of 214 seconds. There was no difference in measurement between the PV and first-order venule, or between baseline and 2-week follow-up. Five of 5 animals survived without incident. On necropsy, there was no evidence of thrombus or hemorrhage. CONCLUSIONS This study represents the first survival study after EUS-guided direct portal pressure measurements using a digital pressure wire. This method appears safe, straightforward, and precise. Measurements of the PV and a first-order portal venule appear equivalent, and serial measurement seems feasible.

Abstract
The concept of ‘cirrhosis’ is evolving and it is now clear that compensated and decompensated cirrhosis are completely different in terms of prognosis. Furthermore, the term ‘advanced chronic liver disease (ACLD)’ better reflects the continuum of histological changes occurring in the liver, which continue to progress even after cirrhosis has developed, and might regress after removing the etiological factor causing the liver disease. In compensated ACLD, portal hypertension marks the progression to a stage with higher risk of clinical complication and requires an appropriate evaluation and treatment. Invasive tests to diagnose cirrhosis (liver biopsy) and portal hypertension (hepatic venous pressure gradient measurement and endoscopy) remain of crucial importance in several difficult clinical scenarios, but their need can be reduced by using different non-invasive tests in standard cases. Among non-invasive tests, the accepted use, major limitations and major benefits of serum markers of fibrosis, elastography and imaging methods are summarized in the present review.

Abstract
INTRODUCTION Hepatic venous pressure gradient (HVPG) measurement is recommended for prognostic and therapeutic indications in centres with adequate resources and expertise. Our study aimed to evaluate the quality of HVPG measurements at our centre before and after introduction of a standardised protocol, and the clinical relevance of the HVPG to variceal bleeding in cirrhotics. METHODS HVPG measurements performed at Singapore General Hospital from 2005-2013 were retrospectively reviewed. Criteria for quality HVPG readings were triplicate readings, absence of negative pressure values and variability of ≤ 2 mmHg. The rate of variceal bleeding was compared in cirrhotics who achieved a HVPG response to pharmacotherapy (reduction of the HVPG to < 12 mmHg or by ≥ 20% of baseline) and those who did not. RESULTS 126 HVPG measurements were performed in 105 patients (mean age 54.7 ± 11.4 years; 55.2% men). 80% had liver cirrhosis and 20% had non-cirrhotic portal hypertension (NCPH). The mean overall HVPG was 13.5 ± 7.2 mmHg, with a significant difference between the cirrhosis and NCPH groups (p < 0.001). The proportion of quality readings significantly improved after the protocol was introduced. HVPG response was achieved in 28 (33.3%, n = 84) cirrhotics. Nine had variceal bleeding over a median follow-up of 29 months. The rate of variceal bleeding was significantly lower in HVPG responders compared to nonresponders (p = 0.025). CONCLUSION The quality of HVPG measurements in our centre improved after the introduction of a standardised protocol. A HVPG response can prognosticate the risk of variceal bleeding in cirrhotics.

Abstract
Background: To examine the influence of the severity of portal hemodynamic abnormality on the prognosis of cirrhosis with respect to the muscle mass loss (MML). Methods: The study involved a subgroup analysis in 98 cirrhosis patients (63.5 ± 11.8 years) who prospectively underwent both Doppler ultrasound and hepatic venous catheterization. The prognostic influence of MML diagnosed by computed tomography using the L3 skeletal muscle index was evaluated (median observation period, 32.7 months). Results: The cumulative survival rate showed difference between patients with MML (n = 34; 82.2%/1year, 41.2%/3years and 36.1%/5years) and those without (n = 64; 92.1%/1year, 74.9%/3years and 69.4%/5years; P = 0.005). When divided with respect to the portal velocity, the survival rate showed differences between patients with and without MML in the cohort < 12.8 cm/s (n=52, p=0.009) and ≥ 12.8 cm/s (n=44, p=0.041). The survival rate also showed differences between patients with MML (n = 24; 78.8%/1year, 40.6%/3years and 34.8%/5years) and those without (n = 45; 91.1%/1year, 71.3%/3years and 63.1%/5years; P = 0.008) in the cohort with hepatic venous pressure gradient (HVPG) > 12 mmHg. However, in the cohort with HVPG ≤ 12 mmHg, survival rate showed no difference between patients with MML (n=10; 100%/1year, 61.9%/3years and 61.9%/5years) and those without (n=19; 93.8%/1year, 71.2%/3years and 59.4%/5years; p = 0.493) Conclusion: Lower HVPG has a compensating effect on the MML-induced poor prognosis of cirrhosis. Care should be taken in the evaluation of the influence of MML in consideration of the severity of portal hypertension.

Abstract
BACKGROUND & AIMS Hepatic venous pressure gradient (HVPG) and transjugular liver biopsy (TJLB) are increasingly used in the management of patients with liver disease. We aimed to describe the safety profile of these procedures, providing data on the intra- and periprocedure complications, radiation exposure and amount of iodinated contrast material used. METHODS In 106 consecutive patients undergoing HVPG and TJLB data on fluoroscopy time (FT), absorbed radiation dose, equivalent effective dose (mSv) and volume of iodinated contrast material (ICM) were prospectively collected and reviewed, together with clinical and laboratory data. Incidence and severity of procedure-related complications were assessed. In 28 hospitalised patients, creatinine values after 72 hours of the procedure were reviewed to identify contrast-induced nephropathy (CIN). RESULTS Median effective radiation dose was 5.4 mSv (IQR 10 mSv). A total 28.3% of patients exceeded an effective exposure of 10 mSv and 9.4% exceeded 20 mSv. Only age and BMI correlated with radiation dose (R = .327, P=.001 and R = .410, P<.0001 respectively), and only BMI remained independently associated with an exposure over 20 mSv. Procedure-related complications occurred in eight patients (7.5%), and were minor in six cases. Median ICM volume was 12.5 mL. 6/28 patients met the diagnostic criteria for CIN. CONCLUSIONS Hepatic venous pressure gradient and Transjugular liver biopsy show a good safety profile and radiation exposure associated with these procedures is in most of the cases low. In hepatic haemodynamic procedures, efforts should be made to reduce the radiation dose in patients with overweight/obesity and to use the minimal possible ICM volume in patients with acute-on-chronic liver failure.

Abstract
BACKGROUND Chronic liver injury can result in fibrosis that may progress over years to end-stage liver disease. The most effective anti-fibrotic therapy is treatment of the underlying disease, however when not possible, interventions to reverse or slow fibrosis progression are needed. AIM The aim of this study was to study the safety and tolerability of simtuzumab, a monoclonal antibody directed against lysyl oxidase-like 2 (LOXL2) enzyme, in subjects with hepatitis C virus (HCV), human immunodeficiency virus (HIV), or HCV-HIV co-infection and advanced liver disease. METHODS Eighteen subjects with advanced liver fibrosis received simtuzumab 700 mg intravenously every 2 weeks for 22 weeks. Transjugular liver biopsies were performed during screening and at the end of treatment to measure hepatic venous pressure gradient (HVPG) and to stage fibrosis. RESULTS Treatment was well-tolerated with no discontinuations due to adverse events. No significant changes were seen in HVPG or liver biopsy fibrosis score after treatment. Exploratory transcriptional and protein profiling using paired pre- and post-treatment liver biopsy and serum samples suggested up-regulation of TGF-β3 and IL-10 pathways with treatment. CONCLUSION In this open-label, pilot clinical trial, simtuzumab treatment was well-tolerated in HCV- and HIV-infected subjects with advanced liver disease. Putative modulation of TGF-β3 and IL-10 pathways during simtuzumab treatment merits investigation in future trials.

Abstract
BACKGROUND & AIMS Indocyanine green retention test (ICG-r15) is a non-invasive marker of functional hepatic reserve. Among patients with compensated cirrhosis, ICG-r15 correlates to the degree of portal hypertension (PH); however, its prognostic relationship with the occurrence of decompensation events still requires clarification. METHODS ICG-r15 was prospectively measured in 154 patients with compensated cirrhosis. Patients with hepatocellular carcinoma (HCC), Child-Pugh B-C, MELD>15, bilirubin > 2 mg/dl, INR > 1.5 or portal vein thrombosis were excluded. All patients underwent laboratory tests, upper endoscopy and hepatic venous pressure gradient (HVPG). Decompensation, development of HCC, liver transplant and death were recorded and analysed through competing-risk analysis. RESULTS The study group was composed of 134 patients who were followed for a median of 39 months. During follow-up, 46 patients (34.3%) developed liver decompensation. Hepatocellular carcinoma occurred in 18 patients and two patients died from non-liver-related causes. The 1-, 2- and 3-year cumulative incidences of decompensation were 9.7%, 28.4% and 33.4% respectively. Patients with ICG-r15 < 10% did not experience any decompensation events during follow-up, while the 3-year cumulative incidence of decompensation of patients with ICG-r15 between 10% and 22.9% was 29.2% and that of patients with ICG-r15 ≥ 23% was 70.0% (P < 0.001). ICG-r15 gave the lowest pseudo-log-likelihood value, in comparison to oesophageal varices present, MELD, low platelet count and HVPG. CONCLUSIONS ICG-r15 appears to be strictly related to liver decompensation, longitudinally confirming the preliminary findings of its correlation with PH among patients with compensated cirrhosis, and can be used for patient prognostication.

Abstract
BACKGROUND AND AIMS The hepatic venous pressure gradient (HVPG) plays an important role in the diagnosis, prognosis and therapy of patients with cirrhosis and portal hypertension. One barrier to its widespread use is the potential for a low reproducibility. We aimed to evaluate the interobserver agreement in the interpretation of optimally acquired HVPG tracings from patients with cirrhosis and different degrees of portal hypertension. METHODS Two hundred and fifteen tracings obtained from 51 patients with cirrhosis in a single centre were interpreted independently by two hepatologists: one experienced observer and one inexperienced observer. Correlation was performed by Pearson linear regression and the intraclass correlation coefficient (ICC). A Bland-Altman plot was constructed to visualize how the differences between observers compared across the range of measurements. Logistic regression was used to identify predictors of ≥10% variation between observers' readings. RESULTS There was a significant linear relationship between observers' readings r = 0.98 (P = 0.001). The ICC between observers (interobserver agreement) was also excellent at 0.991 (P = 0.001). Using the Bland-Altman technique, the mean difference between the observers' readings was 0.2 mmHg (95% CI: -1.2 mmHg to 1.6 mmHg). Thirteen per cent of all readings and 9% of readings with an HVPG of ≥10 mmHg differed by ≥10%. As expected, a lower baseline HVPG was a predictor of this variability. CONCLUSIONS Interobserver reproducibility in the assessment of optimally acquired HVPG tracings is excellent without differences related to experience. The data provide further support that the HVPG can be used accurately in clinical and research settings.

Abstract
BACKGROUND AND AIMS Hepatic venous pressure gradient (HVPG) currently serves as a surrogate for portal pressure measurement but has many limitations. We developed a novel technique for rapid and direct portal pressure measurements using a digital pressure wire delivered through an EUS-guided 22-gauge FNA needle. Our aims were to evaluate (1) the short-term safety and technical feasibility, (2) procedural duration and subjective workload assessment, and (3) accuracy compared with a transjugular criterion standard approach. METHODS The subjects were Yorkshire pigs, weighing 40 to 55 kg. The portal vein was identified by using a linear array echoendoscope and accessed with a commercially available 22-gauge FNA needle preloaded with a digital pressure wire. Access was confirmed by portal venography. Mean digital pressure measurements were recorded over 30 to 60 seconds, and the National Aeronautics and Space Administration Task Load Index was scored. The control measurements were conventional transjugular catheterization with a balloon occlusion catheter to obtain free and wedged hepatic pressures, with subsequent HVPG calculation. RESULTS The total time required for EUS identification and needle access of the portal vein, venography, and digital pressure measurement was less than 5 minutes in 5 of 5 pigs. The National Aeronautics and Space Administration Task Load Index scores revealed a low subjective workload. Baseline portal pressure measurements via EUS ranged from 5 mm Hg to 10 mm Hg (mean, 6.4 mm Hg). HVPG measurements were consistently ±1 mm Hg of portal pressure. CONCLUSIONS This study is the first report of direct EUS-guided portal pressure measurements by using a digital pressure wire. This method is routinely performed in minutes and provides real-time pressure tracings via wireless transmission. This novel approach for direct portal pressure measurement has the potential to replace traditional indirect HVPG measurements.

Abstract
BACKGROUND AND AIM To demonstrate the effect of endoscopic injection sclerotherapy (EIS) with argon plasma coagulation (APC) as a primary/secondary prophylaxis for esophageal varies (EV) on portal hemodynamics and long-term outcomes in cirrhosis. METHODS This prospective study included 48 cirrhotic patients (64.5 ± 11.4 years; 26 bleeders, 22 non-bleeders). Post-treatment outcomes (EIS and APC; median observation period, 12.8 months for recurrence and 21.1 months for prognosis) were evaluated with respect to the findings of hepatic venous catheterization, Doppler ultrasound, and endoscopic ultrasonography (EUS). RESULTS All patients showed EV eradication after endoscopic treatment, and a decreased frequency of a patent left gastric vein (pre: 83.3%, post: 27.1%, P < 0.001). However, hepatic venous pressure gradient (HVPG, mmHg) remained unchanged after the treatment, pre: 16.1 ± 3.6, post: 15.6 ± 3.8 (P = 0.269). Cumulative variceal recurrence/rebleeding rates were 25.5%/5.6% and 62.4%/23.1% at 1 and 3 years, respectively. Post-treatment EUS finding, area of submucosal vessels in the cardia ≥12 mm2 was the only significant factor for variceal recurrence (hazard ratio 9.769, 95% confidence interval 3.046-31.337; P < 0.001). Cumulative recurrence rate was significantly higher in patients with area of submucosal vessels in the cardia ≥12 mm2 (58.3% at 1 year and 100% at 3 years) than in those without (11.4% at 1 year and 40.9% at 3 years, P < 0.001). Cumulative overall survival rates were 95.2% and 71.9% at 1 and 3 years, respectively, showing no significant relationship with HVPG. CONCLUSION EIS with APC for EV is unlikely to have a significant influence on portal pressure.
