Background & Aims Porto-sinusoidal vascular disease (PSVD) was recently proposed as novel clinical entity characterized by typical histological changes with or without portal hypertension (PH) in the absence of cirrhosis. Thus, we aimed to describe clinical characteristics and the outcome of PSVD patients and to compare these to patients meeting traditional idiopathic non-cirrhotic portal hypertension (INCPH) criteria. Methods Patients undergoing liver biopsy (baseline) ±hepatic venous pressure gradient (HVPG) measurement at the Vienna General Hospital between 2000-2019 were screened for PSVD and INCPH criteria. Results 91 patients were diagnosed with PSVD of which 28 (30.8%) also fulfilled INCPH criteria (INCPH+/PSVD+). Specific histological and specific clinical PH signs were found in 72 (79.1%) and 54 (59.3%) patients, respectively. INCPH+/PSVD+ showed higher Child-Pugh-scores (7±2 vs 6±1 points; P = .002) and a higher prevalence of decompensation (57.1% vs 28.6%; P = .009) than INCPH-/PSVD+ patients. Importantly, hepatic decompensation after three years (3Y) occurred in 11.2% of PSVD patients with specific clinical signs of PH, while no decompensation occurred in patients with only specific histological or with unspecific clinical/histological signs (P = .002). When categorizing by INCPH definition, 3Y decompensation was 13.4% in INCPH+/PSVD+ and 3.8% in INCPH-/PSVD+ (P = .120). While overall mortality was similar in INCPH+/PSVD+ (n = 6; 21.4%) and INCPH-/PSVD+ (n = 10; 15.9%) patients (P = .558), liver-related mortality tended to be higher in INCPH+/PSVD+ (6.9%) than in INCPH-/PSVD+ (0%; P = .078). Conclusion Novel PSVD criteria facilitate diagnosis. Compared to INCPH, clinical course of PSVD patients is more favorable. Importantly, specific signs of PH including varices and collaterals are associated with hepatic decompensation and mortality.

Liver fibrosis is the static and main (70%-80%) component of portal hypertension (PH). We investigated dynamic components of PH by a three-dimensional analysis based on correlation of hepatic collagen proportionate area (CPA) with portal pressure (PP) in animals or HVPG in patients.Different animal models (bile duct ligation: n = 31, carbon tetrachloride: n = 12, thioacetamide: n = 12, choline-deficient high-fat diet: n = 12) and patients with a confirmed single etiology of cholestatic (primary biliary cholangitis/primary sclerosing cholangitis: n = 16), alcohol-associated (n = 22), and metabolic (NASH: n = 19) liver disease underwent CPA quantification on liver specimens/biopsies. Based on CPA-to-PP/HVPG correlation, potential dynamic components were identified in subgroups of animals/patients with lower-than-expected and higher-than-expected PP/HVPG. Dynamic PH components were validated in a patient cohort (n = 245) using liver stiffness measurement (LSM) instead of CPA. CPA significantly correlated with PP in animal models (Rho = 0.531; p0.001) and HVPG in patients (Rho = 0.439; p0.001). Correlation of CPA with PP/HVPG varied across different animal models and etiologies in patients. In models, severity of hyperdynamic circulation and specific fibrosis pattern (portal fibrosis: p = 0.02; septa width: p = 0.03) were associated with PH severity. In patients, hyperdynamic circulation (p = 0.04), vascular dysfunction/angiogenesis (VWF-Ag: p = 0.03; soluble vascular endothelial growth factor receptor 1: p = 0.03), and bile acids (p = 0.04) were dynamic modulators of PH. The LSM-HVPG validation cohort confirmed these and also indicated IL-6 (p = 0.008) and hyaluronic acid (HA: p0.001) as dynamic PH components.The relative contribution of "static" fibrosis on PH severity varies by type of liver injury. Next to hyperdynamic circulation, increased bile acids, VWF-Ag, IL-6, and HA seem to indicate a pronounced dynamic component of PH in patients.

The coronavirus disease 2019 (COVID-19) pandemic necessitated down-scaling of in-hospital care to prohibit the spread of severe acute respiratory syndrome-coronavirus-2. We (1) assessed patient perceptions on quality of care by telesurvey (cohort 1) and written questionnaire (cohort 2), and (2) analyzed trends in elective and nonelective admissions before (December 2019 to February 2020) and during (March to May 2020) the COVID-19 pandemic in Austria. A total of 279 outpatients were recruited into cohort 1 and 138 patients into cohort 2. All admissions from December 2019 to May 2020 to the Division of Gastroenterology/Hepatology at the Vienna General Hospital were analyzed. A total of 32.6% (n = 91 of 279) of cohort 1 and 72.5% (n = 95 of 131) of cohort 2 had telemedical contact, whereas 59.5% (n = 166 of 279) and 68.2% (n = 90 of 132) had face-to-face visits. A total of 24.1% (n = 32 of 133) needed acute medical help during health care restrictions; however, 57.3% (n = 51 of 89) reported that contacting their physician during COVID-19 was difficult or impossible. Patient-reported satisfaction with treatment decreased significantly during restrictions in cohort 1 (visual analog scale [VAS] 0-10: 9.0 ± 1.6 to 8.6 ± 2.2; P

Background Bile acids are important endocrine modulators of intestinal and hepatic signalling cascades orchestrating critical pathophysiological processes in various liver diseases. Increasing knowledge on bile acid signalling has stimulated the development of synthetic ligands of nuclear bile acid receptors and other bile acid analogues. Aim This review summarises important aspects of bile acid-mediated crosstalk between the gut and the liver ("gut-liver axis") as well as recent findings from experimental and clinical studies. Methods We performed a literature review on bile acid signalling, and therapeutic applications in chronic liver disease. Results Intestinal and hepatic bile acid signalling pathways maintain bile acid homeostasis. Perturbations of bile acid-mediated gut-liver crosstalk dysregulate transcriptional networks involved in inflammation, fibrosis and endothelial dysfunction. Bile acids induce enterohepatic feedback signalling by the release of intestinal hormones, and regulate enterohepatic circulation. Importantly, bile acid signalling plays a central role in maintaining intestinal barrier integrity and antibacterial defense, which is particularly relevant in cirrhosis, where bacterial translocation has a profound impact on disease progression. The nuclear bile acid farnesoid X receptor (FXR) is a central intersection in bile acid signalling and has emerged as a relevant therapeutic target. Conclusions Experimental evidence suggests that bile acid signalling improves the intestinal barrier and protects against bacterial translocation in cirrhosis. FXR agonists have displayed efficacy for the treatment of cholestatic and metabolic liver disease in randomised controlled clinical trials. However, similar effects remain to be shown in advanced liver disease, particularly in patients with decompensated cirrhosis.

Background & Aims While direct oral anticoagulants (DOACs) are increasingly used in patients with liver disease, safety data especially in advanced chronic liver disease (ACLD) are limited. Methods Liver disease patients receiving DOAC treatment (ACLD: n = 104; vascular liver disease: n = 29) or vitamin K antagonists (VKA)/low-molecular-weight heparin (LMWH; ACLD: n = 45; vascular: n = 13) between January 2010 and September 2020 were retrospectively included. Invasive procedures and bleeding events were recorded. Calibrated anti-Xa peak levels and thrombomodulin-modified thrombin generation assays (TM-TGAs) were measured in a subgroup of 35/28 DOAC patients. Results Among patients receiving DOAC, 55 (41.3%) had advanced liver dysfunction (Child-Pugh-stage [CPS] B/C) and 66 (49.6%) had experienced decompensation. Overall, 205 procedures were performed in 60 patients and procedure-related bleedings occurred in 7 (11.7%) patients. Additionally, 38 (28.6%) patients experienced spontaneous (15 minor, 23 major) bleedings during a median follow-up of 10.5 (IQR: 4.0-27.8) months. Spontaneous bleedings in ACLD patients were more common in CPS-B/C (at 12 months: 36.9% vs CPS-A: 15.9%, subdistribution hazard ratio [SHR]: 3.23 [95% CI: 1.59-6.58], P < .001), as were major bleedings (at 12 months: 22.0% vs 5.0%, SHR: 5.82 [95% CI: 2.00-16.90], P < .001). Importantly, CPS (adjusted SHR: 4.12 [91% CI: 1.82-9.37], P < .001), but not the presence of hepatocellular carcinoma or varices, was independently associated with major bleeding during DOAC treatment. Additionally, ACLD patients experiencing bleeding had worse overall survival (at 12 months: 88.9% vs 95.0% without bleeding; P < .001). Edoxaban anti-Xa peak levels were higher in patients with CPS-B/C (345 [95% CI: 169-395] vs CPS-A: 137 [95% CI: 96-248] ng/mL, P = .048) and were associated with lower TM-TGA. Importantly, spontaneous bleeding rates were comparable to VKA/LMWH patients. Conclusions Anticoagulants including DOACs should be used with caution in patients with advanced liver disease due to a significant rate of spontaneous bleeding events.

Background and Aims Patients with cirrhosis on the liver transplant (LT) waiting list may die or be removed because of complications of portal hypertension (PH) or infections. von Willebrand factor antigen (vWF‐Ag) and C‐reactive protein (CRP) are simple, broadly available markers of these processes. Approach and Results We determined whether addition of vWF‐Ag and CRP to the Model for End‐Stage Liver Disease‐Sodium (MELD‐Na) score improves risk stratification of patients awaiting LT. CRP and vWF‐Ag at LT listing were assessed in two independent cohorts (Medical University of Vienna [exploration cohort] and Mayo Clinic Rochester [validation cohort]). Clinical characteristics, MELD‐Na, and mortality on the waiting list were recorded. Prediction of 3‐month waiting list mortality was assessed by receiver operating characteristics curve (ROC‐AUC). In order to explore potential mechanisms underlying the prognostic utility of vWF‐Ag and CRP in this setting, we evaluated their association with PH, bacterial translocation, systemic inflammation, and circulatory dysfunction. In the exploration cohort (n = 269) vWF‐Ag and CRP both improved the predictive value of MELD‐Na for 3‐month waitlist mortality and showed the highest predictive value when combined (AUC: MELD‐Na, 0.764; MELD‐Na + CRP, 0.790; MELD‐Na + vWF, 0.803; MELD‐Na + CRP + vWF‐Ag, 0.824). Results were confirmed in an independent validation cohort (n = 129; AUC: MELD‐Na, 0.677; MELD‐Na + CRP + vWF‐Ag, 0.882). vWF‐Ag was independently associated with PH and inflammatory biomarkers, whereas CRP closely, and MELD independently, correlated with biomarkers of bacterial translocation/inflammation. Conclusions The addition of vWF‐Ag and CRP—reflecting central pathophysiological mechanisms of PH, bacterial translocation, and inflammation, that are all drivers of mortality on the waiting list for LT—to the MELD‐Na score improves prediction of waitlist mortality. Using the vWFAg‐CRP‐MELD‐Na model for prioritizing organ allocation may improve prediction of waitlist mortality and decrease waitlist mortality.

Background and aims The cardiovascular hormones renin/angiotensin/aldosterone (RAA), brain-type natriuretic peptide (BNP)and arginine-vasopressin (AVP) are key regulators of systemic circulatory homeostasis in portal hypertension (PH). We assessed (i) the activation of renin, BNP and AVP across distinct stages of PH and (ii) whether activation of these hormones correlates with clinical outcomes. Methods Plasma levels of renin, proBNP and copeptin (AVP biomarker) were determined in 663 patients with advanced chronic liver disease (ACLD) undergoing hepatic venous pressure gradient (HVPG) measurement at the Vienna General Hospital between 11/2011 and 02/2019. We stratified for Child stage (A–C), HVPG (6–9 mmHg, 10–15 mmHg, ≥ 16 mmHg) and compensated vs. decompensated ACLD. Results With increasing PH, hyperdynamic state was indicated by higher heart rates (6–9 mmHg: median 71.0 [IQR 18.0] bpm, 10–15 mmHg: 76.0 [19.0] bpm, ≥ 16 mmHg: 80.0 [22.0] bpm; p p = 0.032) and lower serum sodium (6–9 mmHg: 139.0 [3.0] mmol/L, 10–15 mmHg: 138.0 [4.0] mmol/L, ≥ 16 mmHg: 138.0 [5.0] mmol/L; p p p = 0.002) and copeptin (7.8 [7.7] vs. 5.6 [8.0] vs. 10.7 [18.6] pmol/L; p = 0.024) increased with severity of PH. Elevated renin levels independently predicted first hepatic decompensation (adjusted hazard ratio [aHR]: 1.69; 95% confidence interval [95% CI] 1.07–2.68; p = 0.025) and mortality in compensated patients (aHR: 3.15; 95% CI 1.70–5.84; p p = 0.046). Elevated copeptin levels predicted mortality in decompensated patients (aHR: 5.77; 95% CI 1.27–26.33; p = 0.024) and in the overall cohort (aHR: 3.29; 95% CI 1.36–7.95; p = 0.008). ProBNP levels did not predict clinical outcomes. Conclusions The cardiovascular hormones renin, proBNP and AVP are activated with progression of ACLD and PH. Renin activation is a risk factor for hepatic decompensation and mortality, especially in compensated patients. Increased plasma copeptin is a risk factor for mortality, in particular in decompensated patients.

The first occurrence of decompensation constitutes a watershed moment in the natural history of chronic liver disease; it denotes a point of no return in a relevant proportion of patients. Preventive strategies may profoundly decrease cirrhosis-related morbidity and mortality. Removing the primary etiologic factor and cofactors, is key; however, a considerable proportion of patients require additional etiology-independent treatment strategies that target important pathomechanisms promoting decompensation (ie, portal hypertension and systemic inflammation). This article explains the importance of preventing first decompensation and summarizes the evidence for etiologic and etiology-independent (most important, nonselective beta-blockers and statins) therapies.

Introduction Recently, based on data from the PREDICT study, the European Foundation for the Study of Chronic Liver Failure (EF‐CLIF) consortium proposed pathophysiological/prognostic groups in hospitalized patients with cirrhosis: stable decompensated cirrhosis (SDC), unstable decompensated cirrhosis (UDC), pre‐acute‐on‐chronic liver failure (pre‐ACLF), and ACLF. We evaluated the outcomes of these subgroups in a real‐life cohort of hospitalized patients with cirrhosis. Methods Patients with cirrhosis developing first AD between 09/2010 and 12/2017 at the Vienna General Hospital were evaluated for this retrospective analysis. Results Two hundred and ten patients with cirrhosis (aged 57.6 ± 11.8 years) including n = 45 (21.4%) SDC, n = 100 (47.6%) UDC, n = 28 (13.3%) pre‐ACLF, and n = 37 (17.6%) with ACLF were considered. The proposed AD subgroups discriminated between patients with favorable (1‐year mortality: SDC: 6.7% and UDC: 19.6%) and dismal prognosis (90‐day mortality: pre‐ACLF: 42.9%). Interestingly, systemic inflammation gradually increased (e.g., C‐reactive protein, SDC: 0.9 mg/dl, vs. UDC: 2.0 mg/dl vs. pre‐ACLF: 3.2 mg/dl, p

Distinct prognostic stages of advanced chronic liver disease (ACLD) are defined by severity of portal hypertension (PH) and the presence/absence of clinical complications. We characterised the degree of liver dysfunction, PH, and systemic inflammation across the distinct prognostic stages and assessed their relative impact on decompensation and mortality.A single-centre, prospective cohort of ACLD patients undergoing hepatic venous pressure gradient (HVPG) measurement between 01/2017 and 08/2019 were classified into 6 prognostic stages: mild PH (HVPG 6-9 mmHg, S0), clinically significant PH (HVPG ≥10 mmHg without varices, S1), presence of varices (S2), history of variceal bleeding (S3), first non-bleeding decompensation (S4), and further decompensation (S5). The model for end-stage liver disease (MELD), C-reactive protein (CRP), and IL-6 levels were assessed in relation to their predictive value for decompensation and death.Among 168 ACLD patients 78 had compensated (cACLD, S0 = 13; S1 = 21; S2 = 44) and 90 had decompensated (dACLD, S3 = 10; S4 = 58; S5 = 22) disease. MELD increased across all stages (p0.001), whereas HVPG mostly increased within cACLD substages. Significant increases in CRP and IL-6 levels were only noted across dACLD substages. IL-6 was an independent predictor of decompensation at 1-year follow-up in cACLD (hazard ratio [HR] 1.06, 95% CI 1.01-1.10; p = 0.013). In dACLD patients, IL-6 levels predicted death/transplantation after 1-year of follow-up (HR 1.02, 95% CI 1.01-1.03; p = 0.004).HVPG progression occurs mostly in cACLD patients, whereas systemic inflammation, as reflected by IL-6 levels, only increases substantially across dACLD stages. IL-6 levels correlate with the risk of first decompensation in cACLD and of death/transplantation in dACLD patients.Patients with advanced chronic liver disease (ACLD; i.e. liver cirrhosis) have a certain risk of mortality according to their stage of disease. Progression of disease is greatly influenced by increased pressure in the portal venous system (i.e. portal hypertension) and occurrence of clinical complications (i.e. decompensation). Our study demonstrates that systemic inflammation markedly increases across highest disease stages, and the inflammation biomarker IL-6 in blood may specifically indicate risk of disease progression in patients with ACLD.The study is registered at ClinicalTrials.gov (NCT03267615).

Experimental data indicates that placental growth factor (PLGF) is involved in the pathophysiology of portal hypertension (PH) due to advanced chronic liver disease (ACLD). We investigated serum levels of PLGF and its "scavenger", the receptor soluble fms-like tyrosine kinase-1 (sFLT1, or sVEGFR1), in ACLD patients with different severity of PH and portal-hypertensive gastropathy (PHG).PLGF and sVEGFR1 were measured in ACLD patients with hepatic venous pressure gradient (HVPG) ≥6 mmHg (n = 241) and endoscopic evaluation of PHG (n = 216). Patients with pre-/posthepatic PH, TIPS, liver transplantation and hepatocellular carcinoma were excluded.Thirty-two (13%) patients had HVPG 6-9 mmHg, 128 (53%) 10-19 mmHg and 81 (34%) ≥20 mmHg; 141 (59%) had decompensated ACLD (dACLD). PLGF (median 17.2 vs. 20.8 vs. 22.4 pg/mL; p = 0.002), sVEGFR1 (median 96.0 vs. 104.8 vs. 119.3 pg/mL; p 0.001) levels increased across HVPG strata, while PLGF/sVEGFR1 ratios remained similar (0.19 vs. 0.20 vs. 0.18 pg/mL; p = 0.140). The correlation between PLGF and HVPG was weak (Rho = 0.190,95%CI 0.06-0.31; p = 0.003), and the PLGF/sVEGFR1 ratio did not correlate with HVPG (p = 0.331). The area-under-the-receiver operating characteristics (AUROC) for PLGF to detect clinically significant PH (CSPH;i.e. HVPG ≥ 10 mmHg) yielded only 0.688 (0.60-0.78; p 0.001). When compared to ACLD patients without PHG, PLGF levels (20 without vs. 21.4 with mild vs. 17.1 pg/mL with severe PHG, respectively; p = 0.005) and PLGF/sVEGFR1 ratios (0.20 vs. 0.19 vs. 0.17; p = 0.076) did not increase with mild and severe PHG.While PLGF levels tended to increase with severity of PH, the PLGF/sVEGFR1 ratio remained stable across HVPG strata. Neither PLGF nor the PLGF/sVEGFR1 ratio had diagnostic value for prediction of CSPH. The severity of PHG was also not associated with stepwise increases in PLGF levels or PLGF/sVEGFR1 ratio.

Summary Background Despite the availability of effective and well-tolerated direct acting antivirals (DAAs) against hepatitis C virus (HCV) infection, a substantial number of HCV patients remain untreated. Novel strategies targeting HCV patients with poor adherence are urgently needed to enable HCV elimination. Methods We implemented a physician-operated HCV hotline (HCV-Phone) that was promoted within the patient community and referral networks. Previously diagnosed HCV patients were contacted via the HCV-Phone and offered low-barrier access to DAA therapy. Patients/referring physicians could directly call or send messages to the HCV-Phone. The HCV-Phone related and unrelated visits as well as DAA treatment initiations throughout 2019 were documented. Patients were followed until October 2020. This study analyzed treatment initiation, adherence to scheduled visits and outcomes in patients in whom management was assisted by the HCV-Phone. Results Out of 98 patient contacts via the HCV-Phone 74 attended treatment assessment at our clinic. While 15 (20%) patients were HCV-RNA negative and 1 (1%) patient did not initiate therapy, 58 patients were recruited for DAA therapy via the HCV-Phone. A total of 21 additional patients who started DAAs without HCV-Phone assistance required the use of the HCV-Phone infrastructure later on during treatment, resulting in a total of 79 HCV-Phone related DAA therapies. The poor adherence of patients previously diagnosed with HCV at our clinic is underlined by the long duration from HCV diagnosis to DAA therapy of median 37.0 months (IQR 2.7–181.1 months). A total of 55 (70%) HCV patients achieved a sustained virological response (SVR), 5 (6%) discontinued therapy, 1 (1%) had a reinfection, while 10 (13%) and 8 (10%) patients were lost during DAA therapy or follow-up, respectively. Conclusion The implementation of a physician-operated phone hotline for patients with HCV infection facilitated treatment initiation in an HCV population with poor adherence. Mainly due to losses to follow-up, the SVR rate remained suboptimal with 70%.

Liver biopsy remains essential for the diagnostic work-up of patients with liver disease.To evaluate aspiration vs. core-biopsy needles for transjugular liver biopsy (TJLB) in patients undergoing hepatic venous pressure gradient (HVPG) measurements.84 patients undergoing TJLB between 06/2017 and 12/2018 were prospectively included. Liver biopsy specimens were systematically evaluated for quantitative and qualitative criteria such as number of portal tracts, sample length and fragmentation.In direct comparison of paired TJLB specimens (n=35), core-biopsy samples were significantly longer (median 12 vs. 9mm, p=0.012), tended to contain more portal tracts (median 8 vs. 6, p=0.064) and were less fragmented (p0.001), which resulted in better confidence for liver fibrosis assessment (p=0.035). However, a superior quality in terms of less fragmentation of core-biopsy specimens (p0.05) was only confirmed in patients with HVPG ≥10mmHg or liver stiffness measurement40kPa. In contrast, the aspiration needle provided significantly longer samples in patients with HVPG10mmHg (median 21 vs. 12mm, p=0.007) or with liver stiffness measurement20kPa (median 21 vs. 11mm, p=0.025).In patients with HVPG ≥10mmHg, we recommend to performed TJLB using core-biopsy needles, while the aspiration needle provides high quality liver biopsy specimens in patients with HVPG10mmHg.

Background and Aims The liver plays a key role in the storage, metabolism and homeostasis of fat-soluble vitamins. We investigated the relation of Vitamin(Vit)A/D/E serum levels with severity of liver disease and portal hypertension (PHT). Methods VitA/D/E serum levels were assessed in 234 patients with advanced chronic liver disease (ACLD, i.e. hepatic venous pressure gradient [HVPG] ≥ 6 mmHg). Patients with hepatocellular carcinoma, pre-/post-hepatic PHT, TIPS or liver transplantation were excluded. Results Most patients were male (n = 153; 65%) with a median age of 57.6 (49.7–64.5) years. Thirty-two (14%) patients had HVPG 6–9 mmHg, 66 (28%) 10-15 mmHg, and 136 (58%) ≥ 16 mmHg, respectively. VitD deficiency (25-OH-vitamin-D p 1.05 µmol/L) VitA levels, while 58 (25%) had mild (0.70–1.04 µmol/L), 71 (30%) moderate (0.35–0.69 µmol/L), and 42(18%) severe(Rho = −0.409), CTP score (Rho = −0.646), and serum bile acid levels (Rho = −0.531; all p p p p = 0.001) and elevated bile acid levels(>10 µmol/L; OR 3.62; 95%CI 1.61–8.14; p = 0.002) were independently associated with VitA deficiency. Conclusion VitA and VitD but not VitE deficiencies are highly prevalent in ACLD. VitA deficiency strongly correlates with hepatic dysfunction, PHT and bile acid levels and is associated with decompensated ACLD. Trial registration number NCT03267615.

Background & Aims To explore whether sarcopenia, diagnosed by an abbreviated magnetic resonance imaging (MRI) protocol is a risk factor for hepatic decompensation and mortality in patients with chronic liver disease (CLD). Methods In this retrospective single‐centre study we included 265 patients (164 men, mean age 54 ± 16 years) with CLD who had undergone MRI of the liver between 2010 and 2015. Transverse psoas muscle thickness (TPMT) was measured on unenhanced and contrast‐enhanced T1‐weighted and T2‐weighted axial images. Sarcopenia was defined by height‐adjusted and gender‐specific cut‐offs in women as TPMT

Background Rotational thromboelastometry (ROTEM) has been studied in patients with advanced chronic liver disease (ACLD) without considering the impact of portal hypertension. We evaluated the influence of the hepatic venous pressure gradient (HVPG) on ROTEM results in patients with ACLD. Methods Cross-sectional study; ACLD patients undergoing HVPG measurement within the prospective Vienna Cirrhosis Study (NCT03267615) underwent concomitant ROTEM testing. Results Among 159 patients (68% male; Child–Pugh-A: 53%, Child–Pugh-B: 34%, Child–Pugh-C: 13%), 21 patients (13%) had a HVPG between 6 and 10 mmHg, 84 patients (53%) between 10 and 19 mmHg, and 54 patients (34%) ≥ 20 mmHg. Child–Pugh-C patients (vs. Child–Pugh-A and vs. Child–Pugh-B patients, respectively) showed longer clot formation time (CFT: median 187 s vs. 122 s vs. 122 s, p = 0.007) and lower maximum clot firmness (MCF: median: 45 mm vs. 56 mm vs. 56 mm, p = 0.002) in extrinsic thromboelastometry (EXTEM), while platelet counts were similar across Child–Pugh stages. In the overall cohort, ROTEM parameters did not differ by severity of portal hypertension. However, among compensated Child–Pugh-A patients, MCF decreased with increasing portal pressure, i.e. in higher HVPG strata (HVPG 9–10 mmHg: median MCF: 59 mm vs. HVPG 10–19 mmHg: 56 mm vs HVPG ≥ 20 mmHg: 54 mm, p = 0.023). Furthermore, patients with short CFT and high MCF in EXTEM had higher levels of lipopolysaccharide-binding protein, C-reactive protein, and procalcitonin, as well as higher leukocyte counts (all p Conclusions Portal hypertension seems to impact ROTEM results only in compensated Child–Pugh-A patients. Bacterial translocation and systemic inflammation may trigger a procoagulant state in patients with ACLD.

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

Summary Background and aims Portal hypertensive gastropathy (PHG) is common in patients with cirrhosis and may cause bleeding. This study systematically explored the independent impact of patient characteristics, portal hypertension and hepatic dysfunction on PHG severity and associated anemia. Methods Patients with cirrhosis undergoing endoscopy were included in this retrospective analysis and PHG was endoscopically graded as absent, mild or severe. Clinical and laboratory parameters and hepatic venous pressure gradient (HVPG) were assessed with respect to an association with severity of PHG. Results A total of 110 patients (mean age: 57 years, 69% male) with mostly alcoholic liver disease (49%) or viral hepatitis (30%) were included: 15 (13.6%) patients had no PHG, 59 (53.6%) had mild PHG, and 36 (32.7%) had severe PHG. Severe PHG was significantly associated with male sex (83.3% vs. 62.2% in no or mild PHG; p = 0.024) and higher Child-Turcotte-Pugh (CTP) stage (CTP-C: 38.9% vs. 27.0% in no or mild PHG; p = 0.030), while MELD was similar (p = 0.253). Patients with severe PHG had significantly lower hemoglobin values (11.2 ± 0.4 g/dL vs. 12.4 ± 0.2 g/dL; p = 0.008) and a higher prevalence of iron-deficiency anemia (IDA: 48.5% vs. 26.9%; p = 0.032). Interestingly, HVPG was not significantly higher in severe PHG (median 20 mm Hg) vs. mild PHG (19 mm Hg) and no PHG (18 mm Hg; p = 0.252). On multivariate analysis, CTP score (odds ratio, OR: 1.25, 95% confidence interval, CI 1.02–1.53; p = 0.033) was independently associated with severe PHG, while only a trend towards an independent association with IDA was observed (OR: 2.28, 95% CI 0.91–5.72; p = 0.078). Conclusion The CTP score but not HVPG or MELD were risk factors for severe PHG. Importantly, anemia and especially IDA are significantly more common in patients with severe PHG.

Background Gadoxetic acid-enhanced MRI enables estimation of liver function in patients with chronic liver disease (CLD). The functional liver imaging score (FLIS), derived from gadoxetic acid-enhanced MRI, has been shown to predict transplant-free survival in liver transplant patients. Purpose To investigate the accuracy of the FLIS for predicting hepatic decompensation and transplant-free survival in patients with CLD. Materials and Methods Patients with CLD who had undergone gadoxetic acid-enhanced liver MRI, including T1-weighted volume-interpolated breath-hold examination sequences with fat suppression, performed between 2011 and 2015 were included. FLIS was assigned on the basis of the sum of three hepatobiliary phase features, each scored on an ordinal 0-2 scale: hepatic enhancement, biliary excretion, and the signal intensity in the portal vein. Patients were stratified into the following three groups according to fibrosis stage and a presence or history of hepatic decompensation: nonadvanced CLD, compensated advanced CLD (CACLD), and decompensated advanced CLD (DACLD). The predictive value of FLIS for first and/or further hepatic decompensation and for transplant-free survival was investigated by using Kaplan-Meier analysis, log-rank tests, and Cox regression analysis. Results This study evaluated 265 patients (53 years ± 14 [standard deviation]; 164 men). Intraobserver (κ = 0.98; 95% confidence interval: 0.97, 0.99) and interobserver (κ = 0.93; 95% confidence interval: 0.90, 0.95) agreement for FLIS were excellent. In patients with CACLD, the FLIS was independently predictive of a first hepatic decompensation (adjusted hazard ratio, 3.7; 95% confidence interval: 1.1, 12.6; P = .04), but not for further hepatic decompensations in patients with DACLD (adjusted hazard ratio, 1.4; 95% confidence interval: 0.9, 1.9; P = .17). The FLIS was an independent risk factor for mortality in both patients with CACLD (adjusted hazard ratio, 7.4; 95% confidence interval: 2.7, 20.2; P < .001) and those with DACLD (adjusted hazard ratio, 3.8; 95% confidence interval: 1.7, 9.5; P = .004). Conclusion The functional liver imaging score derived from gadoxetic acid-enhanced MRI identified patients with advanced chronic liver disease who are at increased risk for a first hepatic decompensation and for mortality. © RSNA, 2019 Online supplemental material is available for this article.

Background & Aims The loss‐of‐function rs72613567 T > TA‐variant in the 17β‐hydroxysteroid dehydrogenase 13 (HSD17B13) gene might protect from alcoholic and non‐alcoholic fatty liver disease (ALD/NAFLD) and associated fibrosis/cirrhosis. We investigated the impact of the T > TA‐variant on hepatic decompensation and mortality and investigated its implications on retinol and sex steroid metabolism in patients who had already developed advanced chronic liver disease (ACLD). Methods Retrospective analysis in prospectively characterized patients with viral hepatitis‐ and ALD/NAFLD‐induced portal hypertension (hepatic venous pressure gradient (HVPG) ≥ 6 mmHg) diagnosed at the Medical University of Vienna. Results Among 487 patients who were followed longitudinally, 166 (34%) were heterozygous and 24 (5%) were homozygous for the ‘protective’ TA‐allele. Patients harbouring at least one TA‐allele had a lower MELD (9 (8‐12) vs 10 (8‐13) points; P = .003) and showed a trend towards lower HVPG (16 ± 6 vs 17 ± 7 mmHg; P = .067). Interestingly, in competing risk analyses adjusted for age, HVPG and MELD, harbouring the TA‐allele was associated with numerically increased risks for mortality (adjusted subdistribution hazard ratio (aSHR): 1.3 (95% confidence interval (95% CI): 0.888‐1.91); P = .18), liver‐related death (aSHR: 1.34 (95% CI: 0.9‐1.98); P = .15) and hepatic decompensation (aSHR: 1.29 (95% CI: 0.945‐1.77); P = .11). This might be explained by trends towards worse outcomes (eg liver‐related death: aSHR: 1.64 (95% CI: 0.95‐2.84); P = .076) in patients with viral hepatitis‐induced ACLD. In a cross‐sectional analysis of 211 additional patients, serum retinol levels were comparable between HSD17B13 genotypes, but in males, serum testosterone levels numerically decreased with an increasing number of TA‐alleles. Conclusion In patients with viral hepatitis‐ and ALD‐induced portal hypertension, the T > TA‐variant was not protective of hepatic decompensation and mortality. Further studies should investigate the pathophysiological mechanisms underlying the effects of HSD17B13 genotype at different stages of liver disease.

BACKGROUND AND AIMS Despite vaccination recommendations, hepatitis B (HBV) and D (HDV) coinfections are common in HIV+individuals. METHODS HBV immunization status (anti-HBs) as well as HBV (HBsAg/HBV-DNA) and HDV (anti-HDV) coinfection rates were assessed in 1870 HIV+individuals at HIV diagnosis (baseline, BL) and last follow-up (FU). RESULTS Sixty-eight (3.6%) HIV patients were never tested for HBV. At BL, 89/1802 (4.9%) HIV patients were HBV coinfected. Four hundred and fifteen (23.0%) showed virological HBV clearance [HBsAg(-)/anti-HBc(+)/anti-HBs(+)] and 210 (11.7%) presented with anti-HBc(+) only. Seven hundred and ten (39.4%) were HBV naive [HBsAg(-)/anti-HBs(-)/anti-HBc(-)/HBV-DNA(-)], but only 378 (21.0%) received vaccinations with detectable anti-HBs(+) titres. Among the 89 HBV/HIV-coinfected patients, only 52 (58.4%) were tested for HDV: 11/49 (22.4%) had anti-HDV(+) and 3/12 (25.0%) showed HDV-RNA viraemia. During a median FU of 6.5 (IQR 7.2) years, 44 (4.6%) of the 953 retested BL HBV-negative patients acquired new HBV infection (including 15/304, 4.9% of vaccinated patients). Of the 89 patients, 22 (24.7%) patients cleared their HBsAg, resulting in 60/1625 (3.7%) HIV/HBV individuals at FU: 34 (56.7%) showed HBV-DNA suppression and 15 (25.0%) were HBV viraemic, while 12/89 (13.5%) remained without a FU test. Vaccinations induced anti-HBs(+) in 137 of the retested 649 (21.1%) BL HBV-naive patients. CONCLUSION HBV testing is well established among Viennese HIV+patients with HBV coinfection rates around 4%-5%. HBV vaccinations are insufficiently implemented since anti-HBs titres were detected in only 21.1% of HBV-naive HIV(+) patients and new HBV infections occurred in previously vaccinated patients. HDV testing is not systematically performed despite up to 25% of HIV/HBV patients may show HDV coinfection.

Renal dysfunction occurs frequently in hospitalized patients with advanced chronic liver disease (ACLD)/cirrhosis and has profound prognostic implications. In ACLD patients with ascites, hepatorenal syndrome (HRS) may result from circulatory dysfunction that leads to reduced kidney perfusion and glomerular filtration rate (in the absence of structural kidney damage). The traditional subclassification of HRS has recently been replaced by acute kidney injury (AKI) type of HRS (HRS-AKI) and non-AKI type of HRS (HRS-NAKI), replacing the terms "HRS type 1" and "HRS type 2", respectively. Importantly, the concept of absolute serum creatinine (sCr) cutoffs for diagnosing HRS was partly abandoned and short term sCr dynamics now may suffice for AKI diagnosis, which facilitates early treatment initiation that may prevent the progression to HRS-AKI or increase the chances of AKI/HRS-AKI reversal. Recent randomized controlled trials have established (a) the efficacy of (long-term) albumin in the prevention of complications of ascites (including HRS-AKI), (b) the benefits of transjugular intrahepatic portosystemic shunt placement in patients with recurrent ascites, and (c) the superiority of terlipressin over noradrenaline for the treatment of HRS-AKI in the context of acute-on-chronic liver failure. This review article aims to summarize recent advances in the understanding and management of HRS.

Portal hypertension (PHT) in advanced chronic liver disease (ACLD) results from increased intrahepatic resistance caused by pathologic changes of liver tissue composition (structural component) and intrahepatic vasoconstriction (functional component). PHT is an important driver of hepatic decompensation such as development of ascites or variceal bleeding. Dysbiosis and an impaired intestinal barrier in ACLD facilitate translocation of bacteria and pathogen-associated molecular patterns (PAMPs) that promote disease progression via immune system activation with subsequent induction of proinflammatory and profibrogenic pathways. Congestive portal venous blood flow represents a critical pathophysiological mechanism linking PHT to increased intestinal permeability: The intestinal barrier function is affected by impaired microcirculation, neoangiogenesis, and abnormal vascular and mucosal permeability. The close bidirectional relationship between the gut and the liver has been termed “gut-liver axis”. Treatment strategies targeting the gut-liver axis by modulation of microbiota composition and function, intestinal barrier integrity, as well as amelioration of liver fibrosis and PHT are supposed to exert beneficial effects. The activation of the farnesoid X receptor in the liver and the gut was associated with beneficial effects in animal experiments, however, further studies regarding efficacy and safety of pharmacological FXR modulation in patients with ACLD are needed. In this review, we summarize the clinical impact of PHT on the course of liver disease, discuss the underlying pathophysiological link of PHT to gut-liver axis signaling, and provide insight into molecular mechanisms that may represent novel therapeutic targets.

Background Anaemia is common in advanced chronic liver disease (ACLD) as a result of various risk factors. Aims & Methods We evaluated the prevalence and severity of anaemia as well as the impact of anaemia on clinical outcomes in consecutive patients with ACLD and portal hypertension. Results Among 494 patients, 324 (66%) patients had anaemia. Anaemic patients showed higher MELD (12 ± 4 vs 9 ± 3; P

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is defined as an ascitic polymorphonuclear cell count (A-PMN) > 250 cells/µl. OBJECTIVE: We aimed to investigate the prognostic value of ascitic fluid cell counts in patients without SBP. PATIENTS AND METHODS: A total of 178 patients were included and stratified by ascitic cell counts at index paracentesis: A-LEUK-low (500/µl) for leukocytes; A-PMN-low (250/µl) for PMN cells. RESULTS: One-year mortality was comparable between group A-LEUK-SBP (53.9%) and patients with subclinical cell counts (34.5% for A-LEUK-low, 43.5% for A-LEUK-intermediate, log-rank p = 0.547). However, we observed an increase in one-year mortality already in group A-PMN-intermediate with 75% and A-PMN-SBP with 80.9% (vs 40.5% for A-PMN-low, log-rank p = 0.016). Importantly, increases of A-PMN cell counts between two paracenteses were associated with increased mortality: per 100 cells/µl increase of absolute A-PMN cell count: hazard ratio (HR): 1.03 (95% confidence interval (CI): 1.01–1.06), p = 0.005; per 5% increase of relative PMN cell count: HR: 1.15 (95% CI: 1.06–1.26), p = 0.001. CONCLUSION: Patients with PMN cell counts of 125–250/µl are at high risk for mortality, which was very similar to SBP patients with PMN cell counts >250/µl. This highlights the need for preventive strategies. The prognostic value of changes in relative ascitic PMN cell counts should be evaluated in future studies.

Background and Aim The nuclear farnesoid X receptor (FXR) regulates critical pathways of hepatic metabolism, inflammation, and gut mucosal barrier. Thus, we investigated the association of FXR‐single nucleotide polymorphism (SNPs) with hepatic decompensation and liver‐related mortality in patients with advanced chronic liver disease. Methods Two FXR‐SNPs (rs56163822 G > T and rs35724 G > C) were genotyped in a cohort of 402 prospectively characterized patients with hepatic venous pressure gradient (HVPG) ≥ 6 mmHg. Results Only 19 patients (4.7%) harbored a rs56163822 T‐allele and had less pronounced liver disease as indicated by lower Child–Pugh score (CPS, 6 ± 1 vs 7 ± 2 points, P = 0.034) and higher albumin levels (38.9 ± 4.9 vs 35.9 ± 5.9 g/L, P = 0.026). In contrast, n = 267 (66.4%) patients harbored minor rs35724 allele (G/C or C/C) and had more advanced liver disease, as indicated by a higher model of end‐stage liver disease (11 ± 4 vs 10 ± 3, P = 0.016), while other baseline characteristics were similar across FXR‐SNP genotypes. In compensated CPS‐A patients, the rs35724 minor allele was independently protective for the development of ascites (adjusted hazard ratio [aHR] = 0.411, 95% confidence interval (95% CI): 0.191–0.885; P = 0.023) and tended to reduce the risk of hepatic decompensation (aHR = 0.625, 95% CI: 0.374–1.044, P = 0.072) in multivariate analyses. Of note, transplant‐free survival was longer in patients with rs35724 minor allele and HVPG ≥ 10 mmHg (at 5 years: 68.2% vs 55.8%, P = 0.047) and those with HVPG ≥ 16 mmHg (63.3% vs 44.0%, P = 0.021). After adjusting for established risk factors, the rs35724 minor allele was independently associated with reduced liver‐related mortality in the overall cohort (aHR = 0.658, 95% CI: 0.434–0.998, P = 0.049), in compensated CPS‐A patients (aHR = 0.488, 95% CI: 0.252–0.946, P = 0.034), in patients with HVPG ≥ 10 mmHg (aHR = 0.547, 95% CI: 0.346–0.864, P = 0.010), and in patients with HVPG ≥ 16 mmHg (aHR = 0.519, 95% CI: 0.307–0.878, P = 0.014). Conclusion The FXR‐SNP rs35724 was associated with a reduced risk for development of ascites and liver‐related mortality in patients with advanced chronic liver disease.

BACKGROUND & AIMS Nonselective beta blockers (NSBBs) exert beneficial effects beyond lowering hepatic venous pressure gradient (HVPG), which may be particularly relevant in patients with decompensated cirrhosis (DC), in whom bacterial translocation and bacterial-induced systemic inflammation drive the development of complications such as acute-on-chronic liver failure (ACLF). We evaluated whether NSBB-related changes in von Willebrand factor (VWF) may serve as a biomarker for these effects. METHODS In this retrospective analysis, 159 prospectively characterized patients with clinically stable DC (ie, without acute decompensation) who underwent paired HVPG/VWF assessments before/on NSBB therapy were classified as 'VWF-responders' (as defined by a ≥5% decrease in VWF) versus 'VWF-non-responders.' RESULTS There were no major differences in baseline characteristics between VWF-responders (61%) and VWF-non-responders. VWF-responders showed more pronounced decreases in inflammation (procalcitonin), whereas rates of HVPG-response were similar. In line, NSBB-related changes in VWF correlated with the dynamics of bacterial translocation/inflammation (lipopolysaccharide-binding protein, C-reactive protein, and procalcitonin), rather than those of HVPG. Interestingly, VWF-responders also showed less pronounced NSBB-related decreases in mean arterial pressure, suggesting an amelioration of systemic vasodilatation. Finally, VWF-response was associated with decreased risks of further decompensation (adjusted hazard ratio [aHR], 0.555; 95% confidence interval [CI], 0.337-0.912; P = .020), ACLF (aHR, 0.302; 95% CI, 0.126-0.721; P = .007), and liver-related death (aHR, 0.332; 95% CI, 0.179-0.616; P < .001) in Cox regression models adjusted for prognostic factors including changes in HVPG. CONCLUSIONS Decreases in VWF upon NSBB therapy reflect their anti-inflammatory activity, are accompanied by less pronounced adverse effects on systemic hemodynamics, and are independently associated with a decreased risk of further decompensation, ACLF, and death. VWF-response may discriminate between decompensated patients who benefit from NSBB treatment and have a favorable prognosis versus patients with poor outcomes.

BACKGROUND AND AIMS Non-alcoholic steatohepatitis has become a leading cause of cirrhosis. The prognostic value of (HVPG)-guided NSBB prophylaxis remains to be investigated in the setting of NASH cirrhosis. METHODS Patients with NASH cirrhosis and varices undergoing HVPG-guided NSBB therapy were included. HVPG-response to NSBBs was evaluated within a median 52 (IQR:28-71) days after baseline measurement. HVPG-Response was defined as a decrease of ≥10% from baseline or below

Genetic variants including PNPLA3-rs738409 C&gt, G, TM6SF2-rs58542926 C&gt, T, MBOAT7-rs641738 C&gt, T, and HSD17B13-rs72613567 T&gt, TA have been shown to influence progression to advanced chronic liver disease (ACLD) in patients with chronic hepatitis C (CHC). We aimed to investigate their impact on disease regression (i.e., changes in hepatic venous pressure gradient [HVPG] and non-invasive surrogates [liver stiffness measurement (LSM), von Willebrand factor (VWF), and VWF/platelet count ratio (VITRO)]) and clinical outcomes after CHC cure in 346 patients with pre-treatment ACLD. Patients carrying the PNPLA3 minor allele had more advanced liver disease prior to antiviral therapy, confirming its impact on liver disease progression. In a subgroup of 88 patients who underwent paired HVPG-measurements and were genotyped for all SNP/indels, PNPLA3/TM6SF2/MBOAT7/HSD17B13 genotypes were not associated with changes in HVPG. In line, changes in non-invasive surrogates of portal hypertension (LSM/VWF/VITRO) were comparable between carriers and non-carriers of the PNPLA3 G-allele in the overall cohort. Finally, carriage of PNPLA3 G-allele was not associated with the development of hepatic decompensation, de-novo hepatocellular carcinoma, or transplant-free mortality during a median follow-up of 42 months after the end of antiviral treatment. Therefore, genetic variants in PNPLA3/TM6SF2/MBOAT7/HSD17B13 do not impact the regression of portal hypertension and clinical outcomes in patients with pre-treatment ACLD after CHC cure.

ObjectiveLiver stiffness measurement (LSM) is a tool used to screen for significant fibrosis and portal hypertension. The aim of this retrospective multicentre study was to develop an easy tool using LSM for clinical outcomes in advanced chronic liver disease (ACLD) patients.DesignThis international multicentre cohort study included a derivation ACLD patient cohort with valid two-dimensional shear wave elastography (2D-SWE) results. Clinical and laboratory parameters at baseline and during follow-up were recorded. LSM by transient elastography (TE) was also recorded if available. The primary outcome was overall mortality. The secondary outcome was the development of first/further decompensation.ResultsAfter screening 2148 patients (16 centres), 1827 patients (55 years, 62.4% men) were included in the 2D-SWE cohort, with median liver SWE (L-SWE) 11.8 kPa and a model for end stage liver disease (MELD) score of 8. Combination of MELD score and L-SWE predict independently of mortality (AUC 0.8). L-SWE cut-off at ≥20 kPa combined with MELD ≥10 could stratify the risk of mortality and first/further decompensation in ACLD patients. The 2-year mortality and decompensation rates were 36.9% and 61.8%, respectively, in the 305 (18.3%) high-risk patients (with L-SWE ≥20 kPa and MELD ≥10), while in the 944 (56.6%) low-risk patients, these were 1.1% and 3.5%, respectively. Importantly, this M10LS20 algorithm was validated by TE-based LSM and in an additional cohort of 119 patients with valid point shear SWE-LSM.ConclusionThe M10LS20 algorithm allows risk stratification of patients with ACLD. Patients with L-SWE ≥20 kPa and MELD ≥10 should be followed closely and receive intensified care, while patients with low risk may be managed at longer intervals.

Background and Aims Risk stratification after cure from hepatitis C virus (HCV) infection remains a clinical challenge. We investigated the predictive value of noninvasive surrogates of portal hypertension (liver stiffness measurement [LSM] by vibration‐controlled transient elastography and von Willebrand factor/platelet count ratio [VITRO]) for development of hepatic decompensation and hepatocellular carcinoma in patients with pretreatment advanced chronic liver disease (ACLD) who achieved HCV cure. Approach and Results A total of 276 patients with pretreatment ACLD and information on pretreatment and posttreatment follow‐up (FU)‐LSM and FU‐VITRO were followed for a median of 36.6 months after the end of interferon‐free therapy. FU‐LSM (area under the receiver operating characteristic curve [AUROC]: 0.875 [95% confidence interval [CI]: 0.796‐0.954]) and FU‐VITRO (AUROC: 0.925 [95% CI: 0.874‐0.977]) showed an excellent predictive performance for hepatic decompensation. Both parameters provided incremental information and were significantly associated with hepatic decompensation in adjusted models. A previously proposed combined approach (FU‐LSM 25.3 kPa and/or FU‐VITRO > 3.3; 25.0% of patients), the risk of hepatic decompensation at 3 years following treatment was high (17.4%). Patients within the diagnostic gray‐zone for FU‐CSPH (17.8% of patients) had a very low risk of hepatic decompensation during FU (2.6%). The prognostic value of this algorithm was validated in an internal (n = 86) and external (n = 162) cohort. Conclusion FU‐LSM/FU‐VITRO are strongly and independently predictive of posttreatment hepatic decompensation in HCV‐induced ACLD. An algorithm combining these noninvasive markers not only rules in or rules out FU‐CSPH, but also identifies populations at negligible versus high risk for hepatic decompensation. FU‐LSM/FU‐VITRO are readily accessible and enable risk stratification after sustained virological response, and thus facilitate personalized management.

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

ObjectiveSystemic inflammation promotes the development of clinical events in patients with advanced chronic liver disease (ACLD). We assessed whether (1) non-selective beta blocker (NSBB) treatment initiation impacts biomarkers of systemic inflammation and (2) whether these changes in systemic inflammation predict complications and mortality.DesignBiomarkers of systemic inflammation, that is, white blood cell count (WBC), C reactive protein (CRP), interleukin-6 (IL-6) and procalcitonin (PCT) were determined at sequential hepatic venous pressure gradient (HVPG) measurements without NSBB and under stable NSBB intake. The influence of NSBB-related changes in systemic inflammation on the risk of decompensation and liver-related death was analysed using competing risk regression.ResultsOur study comprised 307 stable patients with ACLD (Child-A: 77 (25.1%), Child-B: 161 (52.4%), Child-C: 69 (22.5%), median HVPG: 20 (IQR 17–24) mm Hg) including 231 (75.2%) with decompensated disease.WBC significantly decreased upon NSBB therapy initiation (median: −2 (IQR −19;+13)%, p=0.011) in the overall cohort. NSBB-related reductions of WBC (Child-C: −16 (−30;+3)% vs Child-B: −2 (−16;+16)% vs Child-A: +3 (−7;+13)%, pAn NSBB-related decrease in systemic inflammation (ie, WBC reduction ≥15%) was achieved by n=91 (29.6%) patients and was found to be an independent protective factor of further decompensation (subdistribution HR, sHR: 0.694 (0.49–0.98), p=0.038) in decompensated patients and of liver-related mortality in the overall patient cohort (sHR: 0.561 (0.356–0.883), p=0.013).ConclusionNSBB therapy seems to exert systemic anti-inflammatory activity as evidenced by reductions of WBC and CRP levels. Interestingly, this effect was most pronounced in Child-C and independent of HVPG response. An NSBB-related WBC reduction by ≥15% was associated with a decreased risk of further decompensation and death.

To explore the epidemiology and clinical course of hepatitis A virus (HAV) infections at the Vienna General Hospital. We retrospectively identified patients who were tested positive for HAV-IgM at the Vienna General Hospital form Q1/2008 to Q3/2018. Our definition of severe HAV infection was AST and/or ALT > 5 × above the upper limit of normal (ULN); and liver dysfunction as (i) hepatic encephalopathy or ammonia > 100 μmol/L, (ii) coagulopathy with INR > 1.5, or (iii) jaundice with bilirubin > 5 mg/dL. A total of 578 HAV-IgM (+) were identified, including 31 (5.4%) and 38 (6.6%) without and with liver dysfunction, respectively. A proportional increase in severe HAV cases with and without liver dysfunction occurred in 2016/2017 with (21.5% (vs. 8.0% in the years before; p
