Abstract
Background & Aims Transjugular intrahepatic portosystemic shunt (TIPS) is the most effective therapy for complications of portal hypertension. However, clinical outcomes following TIPS placement vary widely between patients and identifying ideal candidates remains a challenge. Soluble urokinase plasminogen activator receptor (suPAR) is a circulating marker of immune activation that has previously been associated with liver inflammation, but its prognostic value in patients receiving TIPS is unknown. In the present study, we evaluated the potential clinical relevance of suPAR levels in patients undergoing TIPS insertion. Methods suPAR concentrations were measured by ELISA in hepatic vein (HV) and portal vein (PV) blood samples from 99 patients (training cohort) as well as peripheral venous blood samples from an additional 150 patients (validation cohort) undergoing TIPS placement. The association between suPAR levels and patient outcomes was assessed using Kaplan-Meier methods and Cox-regression analyses. Results suPAR concentrations were significantly higher in HV samples compared to PV samples and correlated with PV concentration, the presence of ascites, renal injury, and consequently with the Child-Pugh and MELD scores. Patients with lower suPAR levels had significantly better short- and long-term survival after TIPS insertion, which remained robust after adjustment for confounders in multivariate Cox-regression analyses. Sensitivity analysis showed an improvement in risk prediction in patients stratified by Child-Pugh or MELD scores. In an independent validation cohort, higher levels of suPAR predicted poor transplant-free survival after TIPS, particularly in patients with Child-Pugh A/B cirrhosis. Conclusion suPAR is largely derived from the injured liver and its levels are predictive of outcome in patients undergoing TIPS. suPAR, as a surrogate of hepatic inflammation, may be used to stratify care in patients following TIPS insertion. Impact and implications Transjugular intrahepatic portosystemic shunt (TIPS) is the most effective therapy for complications of portal hypertension. However, clinical outcomes following TIPS placement vary widely between patients and identification of the ideal candidates remains challenging. We show that soluble urokinase plasminogen activator receptor (suPAR), a circulating marker of immune activation that can easily be measured in routine clinical practice, is a novel marker to identify patients who will benefit from TIPS and those who will not.

Abstract
Caroli disease is a rare congenital malformation that predisposes to segmental cystic dilatation of the intrahepatic bile ducts. Banti syndrome is characterized by persistent splenomegaly due to chronic congestion, resulting in a low hematocrit and ultimately leading to pancytopenia. In this report, we describe a 29-year-old woman who presented with a >20-year history of hepatitis B surface antigen positivity and a >1-year history of recurrent fatigue and malaise. On examination, the patient had abdominal distension with marked splenomegaly (7 cm below the ribs) and ascites with tenderness of the abdominal muscles to palpation. A complete blood count showed a low white blood cell count, red blood cell count, and hemoglobin concentration. During the course of treatment, the patient developed multiple symptoms of pancytopenia and concomitant splenomegaly, and she was discharged after total splenectomy with good recovery. The combination of Banti syndrome and Caroli disease results in severe symptoms of portal hypertension.

Yang C, Xiong B. A comprehensive review of prognostic scoring systems to predict survival after transjugular intrahepatic portosystemic shunt placement. PORTAL HYPERTENSION & CIRRHOSIS 2022; 1:133-144.

Abstract
AbstractPatient prognosis after transjugular intrahepatic portosystemic shunt (TIPS) placement is relatively poor and highly heterogeneous; therefore, a prognostic scoring system is essential for survival prediction and risk stratification. Conventional scores include the Child–Turcotte–Pugh (CTP) and model for end‐stage liver disease (MELD) scores. The CTP score was created empirically and displayed a high correlation with post‐TIPS survival. However, the inclusion of subjective parameters and the use of discrete cut‐offs limit its utility. The advantages of the MELD score include its statistical validation and objective and readily available predictors that contribute to its broad application in clinical practice to predict post‐TIPS outcomes. In addition, multiple modifications of the MELD score, by incorporating additional predictors (e.g., MELD‐Sodium and MELD‐Sarcopenia scores), adjusting coefficients (recalibrated MELD score), or combined (MELD 3.0), have been proposed to improve the prognostic ability of the standard MELD score. Despite several updates to conventional scores, a prognostic score has been proposed (based on contemporary data) specifically for outcome prediction after TIPS placement. However, this novel score (the Freiburg index of post‐TIPS survival, FIPS) exhibited inconsistent discrimination in external validation studies, and its superiority over conventional scores remains undetermined. Additionally, several tools display potential for application in specific TIPS indications (e.g., bilirubin‐platelet grade for refractory ascites), and biomarkers of systemic inflammation, nutritional status, liver disease progression, and cardiac decompensation may provide additional value, but require further validation. Future studies should consider the effect of TIPS placement when exploring predictors, as TIPS is a pathophysiological approach that substantially alters systemic hemodynamics and ameliorates bacterial translocation and malnutrition.

Abstract
Background Serum cytokines—reflecting systemic inflammation has been associated with the risk of decompensation and mortality in patients with cirrhosis. However, the role of systemic inflammation in patients with cirrhosis undergoing transjugular intrahepatic portosystemic shunt procedure remains unknown. Patients and Methods Patients with cirrhosis who received transjugular intrahepatic portosystemic shunt between June 2015 and September 2017 were included. Portal and hepatic venous blood samples were obtained intraoperatively; serum cytokine levels (IL-10, IL-17A, IL-1RA, IL-8, and CXCL10) were measured in 105 patients. Associations with survival and other outcomes during long-term follow-up (median: 1,564 days) were assessed using logistic regression. Results IL-17A and CXCL10 levels were higher in the portal than in the hepatic veins, whereas IL-1RA levels were higher in the hepatic than in the portal veins. However, IL-8 or IL-10 levels between hepatic and portal veins showed no differences. Multivariate analysis demonstrated that Child–Pugh scores (P = 0.017, HR: 1.484, 95% CI: 1.072–2.055) and IL-8 level in hepatic veins (P < 0.001, HR: 1.043, 95% CI: 1.019–1.068) were independent predictors for mortality during long-term follow-up, with an optimal cut-off of 5.87 pg/ml for IL-8 in hepatic veins. Patients with hepatic IL-8 levels < 5.87 pg/ml had significantly higher cumulative survival rates (98.4 vs. 72.9% at 1 year, 98.4 vs. 65.3% at 2 years, 96.7 vs. 60.3% at 3 years, 94.2 vs. 60.3% at 4 years; P < 0.0001). Conclusions IL-8 levels in hepatic veins may reflect liver cirrhosis severity. Elevated IL-8 levels suggest shorter survival in patients receiving TIPS.

Abstract
OBJECTIVES Transjugular intrahepatic portosystemic shunt (TIPS) is increasingly used in the management of refractory ascites. Controversy exists regarding the predictive factors of unfavorable outcomes, useful for patient selection. The primary aim was to identify predictive factors of 1-year survival or recurrent severe hepatic encephalopathy in patients with cirrhosis undergoing covered TIPS for refractory ascites. The secondary aim was overall survival. METHODS Observational, retrospective, multicentric study, that included all cirrhotic patients treated with covered-TIPS for refractory ascites since 2001. Demographic, clinical, laboratory and hemodynamic data were collected at baseline and consecutively until dead, liver transplant or end of follow-up. The Cox model was used to identify predictive factors of overall survival. A Fine-Gray competing risk regression model was used to identify predictive factors of 1-year mortality or recurrent hepatic encephalopathy. A predictive nomogram was created based on those factors. RESULTS In total 159 patients were included. Predictive factors of survival or recurrent severe encephalopathy were renal dysfunction [hazard ratio, 2.12 (95% CI, 1.11-4.04); P = 0.022], albumin [hazard ratio, 0.58 (95% CI, 0.34-0.97); P = 0.036], serum sodium [hazard ratio, 0.94 (95% CI, 0.89-0.98); P = 0.008] and international normalized ratio [hazard ratio 4.27 (95% CI, 1.41-12.88); P = 0.010]. In the competing risk analysis, predictive factors of 1-year mortality/recurrent severe encephalopathy in multivariate analysis were age [sub-distribution hazard ratio (sHR) 1.05 (95% CI, 1.02-1.09); P = 0.001], creatinine [sHR 1.55 (95% CI, 1.23-1.96); P = 0.001] and serum sodium [sHR 0.94 (95% CI, 0.90-0.99); P = 0.011] at baseline. CONCLUSIONS Age, creatinine and sodium baseline levels strongly influence 1-year survival/recurrent severe hepatic encephalopathy in patients with cirrhosis undergoing covered TIPS for refractory ascites. A simple nomogram accurately and easily identifies those patients with worse prognosis.

Abstract
Background Pathogenesis of portal hypertension is multifactorial and includes pathologic intrahepatic angiogenesis, whereby TIPS insertion is an effective therapy of portal hypertension associated complications. While angiogenin is a potent contributor to angiogenesis in general, little is known about its impact on TIPS function over time. Methods In a total of 118 samples from 47 patients, angiogenin concentrations were measured in portal and inferior caval vein plasma at TIPS insertion (each blood compartment n = 23) or angiographic intervention after TIPS (each blood compartment n = 36) and its relationship with patient outcome was investigated. Results Angiogenin levels in the inferior caval vein were significantly higher compared to the portal vein (P = 0.048). Ten to 14 days after TIPS, inferior caval vein angiogenin level correlated inversely with the portal systemic pressure gradient (P<0.001), measured invasively during control angiography. Moreover, patients with TIPS revision during this angiography, showed significantly lower angiogenin level in the inferior caval vein compared to patients without TIPS dysfunction (P = 0.01). Conclusion In cirrhosis patients with complications of severe portal hypertension, circulating levels of angiogenin are derived from the injured liver. Moreover, angiogenin levels in the inferior caval vein after TIPS may predict TIPS dysfunction.

Abstract
Portal hypertension, defined as increased pressure in the portal vein, develops as a consequence of increased intrahepatic vascular resistance due to the dysregulation of liver sinusoidal endothelial cells (LSECs) and hepatic stellate cells (HSCs), frequently arising from chronic liver diseases. Extrahepatic haemodynamic changes contribute to the aggravation of portal hypertension. The pathogenic complexity of portal hypertension and the unsuccessful translation of preclinical studies have impeded the development of effective therapeutics for patients with cirrhosis, while counteracting hepatic and extrahepatic mechanisms also pose a major obstacle to effective treatment. In this review article, we will discuss the following topics: i) cellular and molecular mechanisms of portal hypertension, focusing on dysregulation of LSECs, HSCs and hepatic microvascular thrombosis, as well as changes in the extrahepatic vasculature, since these are the major contributors to portal hypertension; ii) translational/clinical advances in our knowledge of portal hypertension; and iii) future directions.

Controlled underdilation using novel VIATORR® controlled expansion stents improves survival after transjugular intrahepatic portosystemic shunt implantation. JHEP Rep 2021; 3:100264. [PMID: 34013182 PMCID: PMC8113713 DOI: 10.1016/j.jhepr.2021.100264] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 02/11/2021] [Accepted: 02/17/2021] [Indexed: 12/11/2022] Open
Abstract
Background & Aims Smaller 8-mm diameter transjugular intrahepatic portosystemic shunts (TIPS) appear to be more beneficial than larger 10-mm TIPS stent-grafts, but lack the ability for secondary dilation in cases of clinical ineffectiveness. Underdilated VIATORR® TIPS stent grafts (VTS) expand passively, whereas novel VIATORR Controlled Expansion (VCX) stent grafts do not. This study evaluated the impact on survival of underdilated VCX compared with VTS in patients with decompensated cirrhosis. Methods This was a prospective case-control study including patients with cirrhosis receiving TIPS using 10-mm VCX underdilated to 8 mm. Patients with cirrhosis receiving 10-mm VTS underdilated to 8 mm were matched for age, sex, indication for TIPS, and liver function. Results A total of 114 patients (47 VCX, 47 VTS, and 20 fully dilated VCX/VTS) were included. After TIPS implantation, underdilated VCX diameter was 8.0 (7.8-9.2) mm at a median time of 359 (87-450) days, compared with VTS at 9.9 (9.7-10.0) mm (p <0.001). The portosystemic pressure gradient immediately after TIPS procedure and after 7 days did not change significantly in VCX [mean 9.4 (± 0.8) vs. 10.4 (± 0.7) mmHg, p = 0.115). Hospital readmission rates for hepatic encephalopathy were 23% (n = 11) vs 51% (n = 24) for VCX and VTS (p <0.001), respectively. Patients with VCX had significantly lower rates of large-volume paracentesis (n = 5 [11%] vs. n = 10 [21%], p = 0.017) and heart failure (n = 1 [2%] vs. n = 7 [15%], p = 0.015). One-year mortality for underdilated VCX and VTS was 15% (n = 7) and 30% (n = 14) and, for fully dilated VCX/VTS, was 45% (n = 9) (log-rank p = 0.008), respectively. Conclusions This study demonstrated that VCX stent grafts underdilated to 8 mm do not passively expand to nominal diameter and suggests reduced hospital readmissions because of hepatic encephalopathy, uncontrolled ascites, and heart failure, and improved 1-year survival compared with underdilated VTS. Lay summary Transjugular intrahepatic portosystemic shunt (TIPS) improves survival in selected patients with liver cirrhosis and acute variceal bleeding or refractory ascites. Smaller 8-mm diameter TIPS stent grafts appear to improve patient outcome compared with larger 10-mm diameter stent grafts. Novel VIATORR® Controlled Expansion (VCX) stent grafts facilitate safe and stable underdilation to 8 mm of large 10-mm diameter stent grafts with improved patient outcome (survival, hepatic encephalopathy, ascites and heart failure) compared with legacy VIATORR TIPS stent graft (VTS). Thus, the use of underdilated VCX could preserve heart function. Clinical Trials Registration The study is registered at Clinicaltrials.govNCT03628807.

Abstract
The human gut microbiome has emerged as a major player in human health and disease. The liver, as the first organ to encounter microbial products that cross the gut epithelial barrier, is affected by the gut microbiome in many ways. Thus, the gut microbiome might play a major part in the development of liver diseases. The common end stage of liver disease is decompensated cirrhosis and the further development towards acute-on-chronic liver failure (ACLF). These conditions have high short-term mortality. There is evidence that translocation of components of the gut microbiota, facilitated by different pathogenic mechanisms such as increased gut epithelial permeability and portal hypertension, is an important driver of decompensation by induction of systemic inflammation, and thereby also ACLF. Elucidating the role of the gut microbiome in the aetiology of decompensated cirrhosis and ACLF deserves further investigation and improvement; and might be the basis for development of diagnostic and therapeutic strategies. In this Review, we focus on the possible pathogenic, diagnostic and therapeutic role of the gut microbiome in decompensation of cirrhosis and progression to ACLF.

Transjugular intrahepatic portosystemic shunt for patients with liver cirrhosis: survey evaluating indications, standardization of procedures and anticoagulation in 43 German hospitals. Eur J Gastroenterol Hepatol 2020; 32:1179-1185.

Abstract
OBJECTIVES Transjugular intrahepatic portosystemic shunt (TIPS) insertion is an established treatment to lower portal pressure. There are no obligatory evidence-based recommendations addressing procedure and anticoagulation. Therefore, a survey was performed to establish current practice at different German hospitals. METHODS A three-page survey was sent out via postal mail to 76 different hospitals addressing the topics indication, contraindication, follow-up and anticoagulation. RESULTS Forty-three hospitals completed the survey: the median number of TIPS/year was 28.6 ± 23. Ascites and hydrothorax were announced as the main indications. Bilirubin levels above 5 mg/dl, hepatic encephalopathy and cardiac disease were considered as absolute contraindications in most hospitals, but age was not. The biggest variations were reported with regard to anticoagulation after TIPS procedure. Four hospitals never used any anticoagulation; most hospitals reported the use of low molecular weight heparins for a period of days up to 4 weeks. But also aspirin or clopidogrel was used after TIPS insertion in eight different hospitals. Additionally, the standards for follow-up after TIPS insertion were different in the hospitals. CONCLUSIONS There is no consensus how to handle indication, contraindications and anticoagulation after the TIPS procedure. A national and international consensus is warranted to improve the outcome of TIPS patients and reduce secondary complications. In addition to compare results and efficacy in the future standard operation procedures as proposed here need to be put in place.

Abstract
Background and Aims: Monocyte chemotactic protein-1 (MCP-1) is a potent chemoattractant for monocytes. It is involved in pathogenesis of several inflammatory diseases. Hepatic MCP-1 is a readout of macrophage activation. While inflammation is a major driver of liver disease progression, the origin and role of circulating MCP-1 as a biomarker remains unclear. Methods: Hepatic CC-chemokine ligand 2 (CCL2) expression and F4/80 staining for Kupffer cells were measured and correlated in a mouse model of chronic liver disease (inhalative CCl4 for 7 weeks). Next, hepatic RNA levels of CCL2 were measured in explanted livers of 39 patients after transplantation and correlated with severity of disease. Changes in MCP-1 were further evaluated in a rat model of experimental cirrhosis and acute-on-chronic liver failure (ACLF). Finally, we analyzed portal and hepatic vein levels of MCP-1 in patients receiving transjugular intrahepatic portosystemic shunt insertion for complications of portal hypertension. Results: In this mouse model of fibrotic hepatitis, hepatic expression of CCL2 (P = 0.009) and the amount of F4/80 positive cells in the liver (P < 0.001) significantly increased after induction of hepatitis by CCl4 compared to control animals. Moreover, strong correlation of hepatic CCL2 expression and F4/80 positive cells were seen (P = 0.023). Furthermore, in human liver explants, hepatic transcription levels of CCL2 correlated with the MELD score of the patients, and thus disease severity (P = 0.007). The experimental model of ACLF in rats revealed significantly higher levels of MCP-1 plasma (P = 0.028) and correlation of hepatic CCL2 expression (R = 0.69, P = 0.003). Particularly, plasma MCP-1 levels did not correlate with peripheral blood monocyte CCL2 expression. Finally, higher levels of MCP-1 were observed in the hepatic compared to the portal vein (P = 0.01) in patients receiving TIPS. Similarly, a positive correlation of MCP-1 with Child-Pugh score was observed (P = 0.018). Further, in the presence of ACLF, portal and hepatic vein levels of MCP-1 were significantly higher compared to patients without ACLF (both P = 0.039). Conclusion: Circulating levels of MCP-1 mainly derive from the injured liver and are associated with severity of liver disease. Therefore, liver macrophages contribute significantly to disease progression. Circulating MCP-1 may reflect the extent of hepatic macrophage activation.

Smaller-Diameter Covered Transjugular Intrahepatic Portosystemic Shunt Stents Are Associated With Increased Survival. Clin Gastroenterol Hepatol 2019; 17:2793-2799.e1. [PMID: 30940552 DOI: 10.1016/j.cgh.2019.03.042] [Citation(s) in RCA: 52] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Revised: 02/16/2019] [Accepted: 03/24/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS We studied the effects of diameter of covered, self-expandable, nitinol stents on survival times of patients with a transjugular intrahepatic portosystemic shunt (TIPS). METHODS We collected data from 185 patients (median age, 55 y; 30% female) who received a covered nitinol stent, from February 2006 through September 2010, using the online multicenter German TIPS registry. TIPS were given to 107 patients for refractory ascites and to 78 patients for variceal bleeding. Patients at risk of hepatic encephalopathy (owing to advanced age, prior episodes) or liver failure (bilirubin level, >3 mg/dL), and bleeding patients receiving variceal embolization at TIPS, received 8-mm stents (n = 53). The remaining patients received 10-mm stents (n = 132). Eighty-one of the 10-mm stents were underdilated using 8-mm dilation balloons. Clinical and biochemical data were collected after TIPS placement at 1 month, 3 months, 6 months, 9 months, 1 year, and thereafter every 3 to 6 months. Groups were compared using propensity score analysis. RESULTS Patients who received 8-mm stents survived significantly longer (34 ± 26 mo) than patients who received 10-mm stents (18 ± 19 mo), regardless of whether they were fully dilated or underdilated. When we compared 10-mm stents with or without underdilation, we found that a significantly higher proportion of patients who received underdilated stents survived for 1 month after TIPS placement (95% vs 84%; P = .03), but not for 3 months (P = .10). In multivariate analysis, 1-year mortality correlated with full dilation of the stent to 10 mm (hazard ratio [HR], 2.0; 95% CI, 1.1-3.5) and with serum creatinine concentration at baseline (HR, 1.5; 95% CI, 1.0-1.7). Five-year mortality was associated with use of the 10-mm stents (HR, 1.8; 95% CI, 1.4-2.7) and baseline concentration of creatinine (HR, 1.3; 95% CI, 1.1-1.6). CONCLUSIONS A smaller stent (nominal diameter of 8 mm, but not underdilation of a 10-mm stent) is associated with a prolonged survival compared with 10-mm stents, independent of liver-specific prognostic criteria.

Abstract
Background Prostanoids are important regulators of platelet aggregation and thrombotic arterial diseases. Their involvement in the development of portal vein thrombosis, frequent in decompensated liver cirrhosis, is still not investigated. Methods Therefore, we used pro-thrombotic venous milieu generation by bare metal stent transjugular intrahepatic portosystemic shunt insertion, to study the role of prostanoids in decompensated liver cirrhosis. Here, 89 patients receiving transjugular intrahepatic portosystemic shunt insertion were included in the study, and baseline levels of thromboxane B2, prostaglandin D2 and prostaglandin E2 were measured in the portal and the hepatic vein. Results While the hepatic vein contained higher levels of thromboxane B2 than the portal vein, levels of prostaglandin E2 and D2 were higher in the portal vein (all P<0.0001). Baseline concentrations of thromboxane B2 in the portal vein were independently associated with an increase of portal hepatic venous pressure gradient during short term follow-up, as an indirect sign of thrombogenic potential (multivariable P = 0.004). Moreover, severity of liver disease was inversely correlated with portal as well as hepatic vein levels of prostaglandin D2 and E2 (all P<0.0001). Conclusions Elevated portal venous thromboxane B2 concentrations are possibly associated with the extent of thrombogenic potential in patients with decompensated liver cirrhosis.

Abstract
Acute-on-chronic liver failure (ACLF) is considered a distinct syndrome in patients with liver disease, with systemic inflammation playing a central role. Portal hypertension (PHT) is also aggravated by inflammation and may subsequently impact the course of ACLF. PHT is more than just an increase in portal pressure in the portal venous system; it aggravates the course of liver disease and, thus, also facilitates the development of acute decompensation and ACLF. A critical mechanistic link between PHT and ACLF might be the gut-liver axis, which is discussed in this review.

Abstract
Among the various risky complications of liver cirrhosis, refractory ascites is associated with poor survival of cirrhotics and persistently worsens their quality of life (QOL). Major clinical guidelines worldwide define refractory ascites as ascites that cannot be managed by medical therapy either because of a lack of response to maximum doses of diuretics or because patients develop complications related to diuretic therapy that preclude the use of an effective dose of diuretics. Due to the difficulty in receiving a liver transplantation (LT), the ultimate solution for refractory ascites, most cirrhotic patients have selected the palliative therapy such as repeated serial paracentesis, transjugular intrahepatic portosystemic shunt, or peritoneovenous shunt to improve their QOL. During the past several decades, new interventions and methodologies, such as indwelling peritoneal catheter, peritoneal-urinary drainage, and cell-free and concentrated ascites reinfusion therapy, have been introduced. In addition, new medical treatments with vasoconstrictors or vasopressin V2 receptor antagonists have been proposed. Both the benefits and risks of these old and new modalities have been extensively studied in relation to the pathophysiological changes in ascites formation. Although the best solution for refractory ascites is to eliminate hepatic failure either by LT or by causal treatment, the selection of the best palliative therapy for individual patients is of utmost importance, aiming at achieving the longest possible, comfortable life. This review briefly summarizes the changing landscape of variable treatment modalities for cirrhotic patients with refractory ascites, aiming at clarifying their possibilities and limitations. Evolving issues with regard to the impact of gut-derived systemic and local infection on the clinical course of cirrhotic patients have paved the way for the development of a new gut microbiome-based therapeutics. Thus, it should be further investigated whether the early therapeutic approach to gut dysbiosis provides a better solution for the management of cirrhotic ascites.

Abstract
OBJECTIVES Immune dysregulation is a hallmark of HIV and hepatitis C virus (HCV) infections. We aimed to evaluate the relationship between liver stiffness measurement (LSM) and biomarkers of T-cell activation, bacterial translocation, inflammation, endothelial dysfunction, and coagulopathy in HIV/HCV-coinfected patients. DESIGN Cross-sectional study. METHODS We studied 238 HIV/HCV-coinfected patients, 32 healthy controls, and 39 HIV-monoinfected patients. Patients were stratified according to LSM into four groups: less than 12.5, 12.5-25, 25-40, and more than 40 kPa. T-cell subsets were measured using flow cytometry and plasma biomarkers using immunoassays. RESULTS HIV/HCV-coinfected patients had higher biomarker levels of immune activation in peripheral blood [T-cell activation (CD4CD38 and CD8CD38), bacterial translocation (soluble CD14), inflammation [IL-1b, IL-6, IL-8, IL-18, IFN-γ-inducible protein 10 (IP-10)] endothelial dysfunction [soluble vascular cell adhesion molecule 1 (sVCAM1), soluble intercellular cell adhesion molecule 1 (sICAM1), and soluble tumor necrosis factor receptor 1 (sTNFR1)], and coagulopathy (plasminogen activator inhibitor-1)] than healthy controls and HIV-monoinfected patients. Moreover, in HIV/HCV-coinfected patients, a direct relationship between LSM and immune activation [T-cell activation (CD8CD38 bacterial translocation (lipopolysaccharide), inflammation (IL-8, IP-10), endothelial dysfunction (sVCAM1, sICAM1, and sTNFR1), and coagulopathy (D-dimer)] was found. Subsequently, patients were stratified into different fibrosis stages, finding that patients with cirrhosis who had LSM at least 40 kPa showed higher biomarker values of immune activation [T-cell activation (CD4CD38 and CD8CD38), bacterial translocation (lipopolysaccharide), inflammation (IL-8, IL-6, IP-10), endothelial dysfunction (sVCAM1, sICAM1, and sTNFR1), and coagulopathy (D-dimer)] than patients from the other three groups (<12.5, 12.5-25, and 25-40 kPa). CONCLUSION T-cell activation, bacterial translocation, inflammation, endothelial dysfunction, and coagulopathy increased with the severity of liver fibrosis in HIV/HCV-coinfected patients, particularly in patients who had LSM at least 40 kPa.

Abstract
BACKGROUND & AIMS CXCR% ligands play an important role in hepatic injury, inflammation and fibrosis. While CXCL9 and CXCL11 are associated with survival in patients receiving transjugular intrahepatic portosystemic shunt (TIPS), the role of CXCL10 in severe portal hypertension remains unknown. METHODS A total of 89 cirrhotic patients were analysed. CXCL10 protein levels were measured in portal and hepatic blood at TIPS insertion and 2 weeks later in 24 patients. CXCL10 and IL8 levels were assessed in portal, hepatic, cubital vein and right atrium blood in a further 25 patients at TIPS insertion. Furthermore, real-time PCR determined hepatic CXCL10-mRNA in 40 cirrhotic patients. RESULTS Hepatic CXCL10 showed no association with decompensation. By contrast, circulating CXCL10-levels were higher in portal than in hepatic vein blood, suggesting an extrahepatic source of CXCL10 in cirrhosis. However, CXCL10 protein in blood samples from portal, hepatic, cubital veins and right atrium correlated excellently with each other and with IL-8 levels. Higher CXCL10 circulating levels were associated with presence of ascites and higher Child scores. Higher CXCL10 circulating protein levels were associated with acute decompensation, acute-on-chronic liver failure (ACLF) and independently with mortality. Moreover, a decrease in CXCL10 protein levels after TIPS insertion was associated with better survival in each cohort and analysed together. DISCUSSION Circulating CXCL10 possibly reflects systemic inflammation and it is correlated with acute decompensation, ACLF and complications in patients with severe portal hypertension receiving TIPS. CXCL10 predicts survival in these patients and a decrease in CXCL10 after TIPS may be considered a good prognostic factor.

Abstract
UNLABELLED Transjugular intrahepatic portosystemic shunt (TIPS) efficiently treats complications of portal hypertension. Liver and spleen stiffness might predict clinically significant portal hypertension. This prospective study investigated liver stiffness in patients receiving TIPS regardless of indication. Of 83 included patients, 16 underwent transient elastography immediately before and 30 minutes after TIPS (acute group), while 67 received shear wave elastography of liver and spleen 1 day before and 7 days after TIPS (chronic group) and were followed further. In blood samples obtained before TIPS from cubital, portal, and hepatic veins, levels of several interleukins (IL1b, IL6, IL8, IL10, IL18) and interferon-gamma were analyzed. In 27 patients (5 acute, 22 chronic), it resulted in an increase in liver stiffness of >10%. In 56 patients, liver stiffness decreased or remained unchanged (<10%). Importantly, spleen stiffness measured by shear wave elastography decreased in all patients (chronic group). None of the clinical or laboratory parameters differed between patients with increase in liver stiffness and those without. Of note, patients with increased liver stiffness showed higher overall and/or hepatic venous levels of proinflammatory cytokines at TIPS and higher incidence of organ failure and worse survival after TIPS. C-reactive protein values and increase of >10% in liver stiffness after TIPS were the only independent predictors of mortality in these patients. CONCLUSION This study demonstrates that the presence of systemic inflammation predisposes patients to develop increased liver stiffness after TIPS, a predictor of organ failure and death.

APTR is a prognostic marker in cirrhotic patients with portal hypertension during TIPS procedure. Gene 2017; 645:30-33.

Abstract
Portal hypertension is a major cause of mortality and morbidity in cirrhotic patients. In this study, we aimed to analyze the clinical characteristics of Alu-mediated p21 transcriptional regulator (APTR) during transjugular intrahepatic portosystemic shunt (TIPS) procedure. Portal and hepatic venous blood was drawn from 84 patients with liver cirrhosis and portal hypertension before and after TIPS treatment. Then, we detected biochemical, hemodynamic parameters and APTR expression before and after TIPS treatment. Indeed, TIPS treatment could markedly ameliorate the serum blood urea nitrogen (BUN) level and portal vein hemodynamics in cirrhotic patients. We found that portal venous levels of APTR was significantly decreased after TIPS treatment and its aberrant expression levels were positively correlated with Model for End Stage Liver Disease (MELD), portal hepatic venous pressure gradient (PHPG) in patients. Higher APTR expression in portal vein was associated with poor prognosis. APTR level in portal vein was an independent predictors of mortality. Our data indicated that APTR may serve as a novel biomarker for cirrhotic patients with portal hypertension before and after receiving TIPS.

Abstract
Alcohol-related liver disease (ALD) remains the most important cause of death due to alcohol. Infections, particularly bacterial infections, are one of the most frequent and severe complications of advanced ALDs, such as alcoholic cirrhosis and severe alcoholic hepatitis (sAH). The specific mechanisms responsible for this altered host defence are yet to be deciphered. The aim of the present study is to review the current knowledge of infectious complications in ALD and its pathophysiological mechanisms, distinguishing the role of alcohol consumption and the contribution of different forms of ALD. To date, corticosteroids are the only treatment with proven efficacy in sAH, but their impact on the occurrence of infections remains controversial. The combination of an altered host defence and corticosteroid treatment in sAH has been suggested as a cause of opportunistic fungal and viral infections. A high level of suspicion with systematic screening and prompt, adequate treatment are warranted to improve outcomes in these patients. Prophylactic or preemptive strategies in this high-risk population might be a preferable option, because of the high short-term mortality rate despite adequate therapies. However, these strategies should be assessed in well-designed trials before clinical implementation.

Abstract
Transjugular intrahepatic portosystemic shunt (TIPS) is used to treat complications of cirrhosis such as variceal bleeding and refractory ascites, but it also bears the risk of liver failure, overt hepatic encephalopathy (HE) and cardiac decompensation. Variceal bleeding may be controlled using endoscopic and medical treatment in patients with compensated cirrhosis; in decompensated patients, however, TIPS improves survival. Therefore, an early TIPS (within 72h or if later, still early after bleeding) might improve the survival of patients by preventing an inflammatory response and bacterial translocation. Both these processes mediate an impaired immunological and hemodynamic response, thereby facilitating the development of acute-on-chronic liver failure (ACLF) and/or death. Similarly, in patients with refractory ascites, TIPS should be used early in treatment to prevent acute kidney injury (AKI) and hepatorenal syndrome (HRS) after precipitating events induced by complications of portal hypertension. Whether TIPS and/or embolization should be used to treat portal vein thrombosis and spontaneous shunts is still a matter of debate and should be further investigated. In summary, the careful selection of patients for TIPS is crucial. New biomarkers, especially those evaluating systemic inflammation and bacterial translocation, might improve the predictive value of established clinical parameters such as bilirubin and overt HE. However, a significant amount of further research must be carried out.

Abstract
BACKGROUND & AIMS Chemokines, such as CXCR3-ligands, have been identified to play an important role during hepatic injury, inflammation and fibrosis. While CXCL9 is associated with survival in patients receiving transjugular intrahepatic portosystemic shunt (TIPS), the role of CXCL11 in severe portal hypertension remains unknown. METHODS CXCL11-levels were measured in 136 patients with liver diseases, and 63 healthy controls. In further 47 cirrhotic patients receiving TIPS, CXCL11 levels were measured in portal and hepatic veins at TIPS insertion by cytometric bead array. CXCL11-levels were measured in 23 patients in cubital vein and right atrium, whereas in 24 patients in portal and hepatic blood at an invasive reevaluation. RESULTS CXCL11-levels were increased with the severity of liver fibrosis. CXCL11-levels from portal, hepatic and cubital veins and right atrium showed a highly significant correlation among each other in these patients. Furthermore, levels of CXCL11 from the right atrium were significantly higher than those from cubital vein. Interestingly, patients with alcoholic cirrhosis had significantly lower CXCL11-levels, than other aetiologies of cirrhosis. After TIPS, CXCL11 levels correlated with the degree of portal pressure and patients with higher CXCL11-levels in portal and hepatic veins showed higher mortality. Multivariate analysis revealed hepatic CXCL11-levels before TIPS, creatinine and age as independent predictors for survival in TIPS patients, whereas MELD score and low portal CXCL11-levels after TIPS predicted long-term survival. CONCLUSION CXCL11 levels are mainly increased in patients with non-alcoholic cirrhosis and high portal pressure. Moreover, levels of CXCL11 might predict long-time survival of cirrhotic patients bearing TIPS.

Abstract
BACKGROUND AND AIMS Progressive fibrosis increases hepatic resistance and causes portal hypertension with complications. During progressive fibrosis remodeling and deposition of collagens and elastin occur. Elastin remodeling is crucially involved in fibrosis progression in animal models and human data. This study investigated the association of circulating elastin with the clinical outcome in cirrhotic patients with severe portal hypertension receiving transjugular intrahepatic porto-systemic shunt (TIPS). METHODS We analyzed portal and hepatic venous samples of 110 cirrhotic patients obtained at TIPS insertion and 2 weeks later. The circulating levels of elastin fragments (ELM) were determined using specific monoclonal ELISA. The relationship of ELM with clinical short-time follow-up and long-term outcome was investigated. RESULTS Circulating levels of ELM showed a gradient across the liver before TIPS with higher levels in the hepatic vein. Interestingly, the circulating ELM levels remained unchanged after TIPS. The circulating levels of ELM in portal and hepatic veins correlated with platelet counts and inversely with serum sodium. Hepatic venous levels of ELM were higher in CHILD C compared to CHILD A and B and were associated with the presence of ascites. Patients with high levels of ELM in the hepatic veins before TIPS showed poorer survival. In multivariate analysis ELM levels in the hepatic veins and MELD were independent predictors of mortality in these patients. CONCLUSION This study demonstrated that circulating levels of ELM are not associated with hemodynamic changes, but might reflect fibrosis remodeling and predict survival in patients with severe portal hypertension receiving TIPS independently of MELD.

Abstract
Bacterial infections are very common in cirrhotic patients, and the incidence is 4-5 times higher than that in the general population. The mechanisms of susceptibility to bacterial infections in cirrhotic patients include intestinal bacterial overgrowth, bacterial translocation, increased number of potentially pathogenic bacteria accompanied by reduced number of beneficial bacteria; small bowel motility disturbances and delayed gut transit, increased intestinal permeability; genetic predisposition to bacterial infections; immunodeficiency accompanied by persistent activation of the immune cells with production of pro-inflammatory cytokines. In this paper, we will discuss the mechanisms of susceptibility to bacterial infections in cirrhotic patients.

Abstract
BACKGROUND & AIMS Inflammation, collagen deposition and tissue remodelling are involved in the pathogenesis and complications of cirrhosis with portal hypertension. CXCL9 and other chemokines play an important role in these processes and have been associated with liver injury and complications of liver disease in humans. However, their predictive value in patients with cirrhosis and portal hypertension remains to be established. METHODS 103 patients with liver cirrhosis who had received TIPS (transjugular intrahepatic portosystemic shunt) were included into this study. The TIPS indication was either refractory ascites or recurrent bleeding. Before and after the TIPS procedure portal and hepatic venous blood samples were obtained in 78 patients. In 25 patients blood samples were obtained from the portal vein, hepatic vein, right atrium and cubital vein at TIPS insertion. Serum levels of CXCL9 were measured by cytometric bead array and correlated with clinical parameters and overall outcome. RESULTS Portal venous levels of CXCL9 decreased after TIPS. Child-Pugh score, refractory ascites, renal dysfunction and alcoholic aetiology of cirrhosis were associated with increased CXCL9 levels. Importantly, low levels of CXCL9 in portal and hepatic vein samples were prognostic factors for the survival of patients receiving TIPS during long-time follow-up. CONCLUSIONS The CXCR3 ligand CXCL9 affects the liver and/or is released by the liver and thereby might contribute to hepatic and extrahepatic organ dysfunction. Elevated levels of CXCL9 are associated with shorter survival in cirrhotic patients with severe portal hypertension receiving TIPS. This chemokine should be further evaluated as a novel biomarker for the outcome in patients with cirrhosis and portal hypertension and its modulation as a new therapeutic strategy.

Abstract
The term cirrhosis-associated immune dysfunction refers to the main syndromic abnormalities of immune function, immunodeficiency and systemic inflammation that are present in cirrhosis. The course of advanced cirrhosis, regardless of its aetiology, is complicated by cirrhosis-associated immune dysfunction and this constitutes the pathophysiological hallmark of an increased susceptibility to bacterial infection, distinctive of the disease. Cirrhosis impairs the homeostatic role of the liver in the systemic immune response. Damage to the reticulo-endothelial system compromises the immune surveillance function of the organ and the reduced hepatic synthesis of proteins, involved in innate immunity and pattern recognition, hinders the bactericidal ability of phagocytic cells. Systemic inflammation, in form of activated circulating immune cells and increased serum levels of pro-inflammatory cytokines, is the result of persistent episodic activation of circulating immune cells from damage-associated molecular patterns, released from necrotic liver cells and, as cirrhosis progresses, from pathogen-associated molecular patterns, released from the leaky gut. Cirrhosis-associated immune dysfunction phenotypes switch from predominantly "pro-inflammatory" to predominantly "immunodeficient" in patients with stable ascitic cirrhosis and in patients with severely decompensated cirrhosis and extra-hepatic organ failure (e.g. acute-on-chronic liver failure), respectively. These cirrhosis-associated immune dysfunction phenotypes represent the extremes of a spectrum of reversible dynamic events that take place during the course of cirrhosis. Systemic inflammation can affect the functions of tissue somatic cells and modify the clinical manifestation of cirrhosis. The best characterized example is the contribution of systemic inflammation to the haemodynamic derangement of cirrhosis, which correlates negatively with prognosis.

Abstract
In patients with chronic liver disease, portal hypertension is driven by progressive fibrosis and intrahepatic vasoconstriction. Interruption of the initiating and perpetuating etiology—mostly leading to necroinflammation—is possible for several underlying causes, such as autoimmune hepatitis, hepatitis B virus (HBV) infection, and most recently hepatitis C virus (HCV) infection. Thus, in the long run, lifestyle-related liver damage due to chronic alcoholism or morbid obesity will remain the main factor leading to portal hypertension. Both causes are probably more easily countered by socioeconomic measures than by individual approaches. If chronic liver injury supporting fibrogenesis and portal hypertension cannot be interrupted, a wide variety of tools are available to modulate and reduce intrahepatic resistance and therewith portal hypertension. Many of these have been evaluated in animal models. Also, some well-established drugs, which are used in humans for other indications (for example, statins), are promising if applied early and concomitantly to standard therapy. In the future, more individually tailored strategies must also be considered in line with the spectrum of portal hypertensive complications and risk factors defined by high-throughput analysis of the patient’s genome, transcriptome, metabolome, or microbiome.

Abstract
In models of diabetic retinopathy, insulin-like growth factor binding protein-3 (IGFBP-3) protects against tumor necrosis factors-alpha (TNF-α)-mediated apoptosis of retinal microvascular endothelial cells (REC), but the underlying mechanisms are unclear. Our current findings suggest that at least two discrete but complimentary pathways contribute to the protective effects of IGFBP-3; 1) IGFBP-3 directly activates the c-Jun kinase/tissue inhibitor of metalloproteinase-3/TNF-α converting enzyme (c-Jun/TIMP-3/TACE), pathway, which in turn inhibits TNF-α production; 2) IGFBP-3 acts through the IGFBP-3 receptor, low-density lipoprotein receptor-related protein 1 (LRP1), to inhibit signaling of TNF-α receptor 2 (TNFR2). Combined, these two IGFBP-3 pathways substantially reduce REC apoptosis and offer potential targets for the treatment of diabetic retinopathy.

Abstract
Background Circulating miRNA-34a is increased in blood of patients with different liver diseases when compared to healthy controls. However, the origin of miRNA-34a and its possible relationship with hemodynamics and outcome in cirrhotic patients with portal hypertension is unknown. We analyzed the levels of miRNA-34a in cirrhotic patients with severe portal hypertension. Methods We included 60 cirrhotic patients receiving TIPS for prevention of rebleeding and/or therapy-refractory ascites. miRNA-34a levels were measured using qPCR and normalized by SV-40 in the portal and hepatic venous blood of these patients taken at TIPS procedure. Hemodynamic and clinical parameters were assessed before TIPS and during follow-up. Results Levels of miRNA-34a were higher in the hepatic vein than in the portal vein. Circulating miRNA-34a in the hepatic vein correlated with ALT, CHE and sodium excretion after TIPS. miRNA-34a showed no correlation with portal pressure, but its levels in the portal vein correlated inversely with the congestion index. Interestingly, the levels of miRNA-34a in the portal and hepatic vein showed inverse correlation with arterial pressure. Furthermore, levels of miRNA-34a in the hepatic vein had a predictive value for survival, but MELD, creatinine at short-time follow-up 14 days after TIPS-insertion and portal pressure after TIPS performed better. Conclusion This study demonstrates for the first time, that miRNA-34a may originate to a large extent from the liver. Even though higher levels of miRNA-34a are possibly associated with better survival at long-term follow-up in cirrhotic patients with severe portal hypertension receiving TIPS, classical prognostic parameters predict the survival better.

Abstract
CONTEXT Portal Hypertension (PH) is a progressive complication due to chronic liver disease. In addition to pathophysiologic changes in the micro-circulation, in PH are established fibrous tissue (periportal fibrous septal) and regenerative hyperplastic nodules (from micro- to macro-nodules) promoting hepatic architectural distortion. EVIDENCE ACQUISITION A literature search of electronic databases was undertaken for the major studies published from 1981 to today. The databases searched were: PubMed, EMBASE, Orphanet, Midline and Cochrane Library. We used the keywords: "portal hypertension, children, immune system, endocrine system, liver fibrosis". RESULTS It is believed that PH results from three "phenotype": ischemia-reperfusion, involving nervous system (NS); edema and oxidative damage, involving immune system; inflammation and angiogenesis, involving endocrine system. However, its exact cause still underdiagnosed and unknown. CONCLUSIONS PH is a dynamic and potentially reversible process. Researchers have tried to demonstrate mechanisms underlying PH and its related-complications. This review focuses on the current knowledge regarding the pathogenesis, and immune, endocrine-metabolic factors of disease. The strong positive association between immune system and development of PH could be efficient to identify non-invasive markers of disease, to modify prognosis of PH, and to development and application of specific and individual anti-inflammatory therapy.
