von Willebrand factor to protein C ratio-related thrombogenicity with systemic inflammation is predictive of graft dysfunction after liver transplantation: Retrospective cohort study. Int J Surg 2020; 84:109-116. [PMID: 33137460 DOI: 10.1016/j.ijsu.2020.10.030] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 10/18/2020] [Accepted: 10/27/2020] [Indexed: 12/29/2022]
Abstract
INTRODUCTION Early allograft dysfunction (EAD) is known to be a prototype of graft failure and ultimately influences long-term graft failure or death. We hypothesized that pretransplant thrombogenicity evaluated by procoagulant and anticoagulant, von Willebrand factor (vWF), factor Ⅷ (FⅧ), protein C (PC) and their imbalance ratio of vWF-to-PC (vWFPCR) and FVIII-to-PC (FⅧPCR), is associated with EAD and 90-day graft failure after living-related liver transplantation (LDLT) and contributes to further exacerbation of graft dysfunction when coexists with systemic inflammation. MATERIAL AND METHODS Of 1199 prospectively registered LDLT patients, 698 with measurements of each thrombogenicity parameters were analyzed. Risk factors for EAD development were searched and subsequent best cut-offs was calculated according to the receiver operator characteristic curve analysis. When comparing the outcome, multivariable regression analysis and inverse probability of treatment weighting (IPTW) of the propensity score were performed. RESULTS The prevalence of EAD was 10.7% (n = 75/698) after LDLT. Of parameters, vWFPCR had highest predictivity potential of EAD with the best cut-off of 8.06. The relationship between vWFPCR≥8.06 showed significant association with EAD development (OR [95%CI], 2.55[1.28-5.09], P = 0.008) and 90-day graft failure (HR [95%CI], 2.24 [1-4.98], P = 0.043) after IPTW-adjustment. Furthermore, risk of EAD increased proportionally with increasing C-reactive protein as a continuous metric of systemic inflammation, and more steeply in those with higher thrombogenicity (i.e., higher vWFPCR). Adding vWFPCR to MELD score improved EAD risk prediction by 21.9%. CONCLUSIONS Pretransplant thrombogenicity assessed by imbalance of pro- and anticoagulant, was significantly associated with EAD and 90-day graft failure after LDLT and this association was worsened by systemic inflammation.

Abstract
Portal vein thrombosis (PVT) is a frequent event in patients with cirrhosis regardless of etiology. Notwithstanding the commonality of the problem, the pathophysiology and risk factors for PVT in cirrhosis are largely unknown. The clinical impact of PVT in the natural history of cirrhosis is unclear, indications for PVT treatment are not well defined, and treatment recommendations are based on experts' opinion and consensus only. Therefore, this review aims to summarize current knowledge of mechanisms and risk factors for PVT development and assess the current evidence of PVT management, with a special focus on strategies of anticoagulation and transjugular intrahepatic portosystemic shunt placement.

Abstract
AbstractBackground Portal vein thrombosis (PVT) is the most common thrombotic complication in cirrhosis; however, local risk factors involved in its pathogenesis are still not fully investigated. The aim of the study was to evaluate hemostasis and endothelial damage in the portal vein in patients with cirrhosis and portal hypertension.Methods Adult cirrhotics undergoing transjugular intrahepatic portosystemic shunt were consecutively enrolled. Rotational thromboelastometry (ROTEM), dosage of total circulating glycosaminoglycans (GAGs), and endotoxemia levels (lipopolysaccharide [LPS]), along with evaluation of endothelial dysfunction by quantification of circulating endothelial microparticles (MPs), were performed on citrated peripheric and portal venous blood samples from each enrolled patient.Results Forty-five cirrhotics were enrolled. ROTEM analysis revealed the presence of a significant heparin-like effect in portal blood (median ɑ angle NATEM 50° vs. HEPTEM 55°, p = 0.027; median coagulation time NATEM 665 s vs. HEPTEM 585 s, p = 0.006), which was not detected in peripheral blood, and was associated with a higher concentration of circulating GAGs. Even though total annexin V-MP circulating MPs were less concentrated in the splanchnic district, the proportion of MPs of endothelial origin, with respect to annexin V-MP, was significantly increased in the portal district (p = 0.036). LPS concentration was higher in portal (197 pg/mL) compared with peripheral blood (165 pg/mL) (p < 0.001).Conclusion Evidences of a damage of glycocalyx along with increased concentration of endothelial MPs suggest the presence of a significant endothelial alteration in the portal vein with respect to peripheral veins. Portal site-specific endothelial damage could hamper its antithrombotic properties and may represent an important local risk factor in the pathogenesis of PVT.

Abstract
Gestational Diabetes Mellitus (GDM) is defined as glucose intolerance that develops in the second or third trimester of pregnancy. GDM can lead to short-term and long-term complications both in the mother and in the offspring. Diagnosing and treating this condition is therefore of great importance to avoid poor pregnancy outcomes. There is increasing interest in finding new markers with potential diagnostic, prognostic and therapeutic utility in GDM. Non-coding RNAs (ncRNAs), including microRNAs, long non-coding RNAs and circular RNAs, are critically involved in metabolic processes and their dysregulated expression has been reported in several pathological contexts. The aberrant expression of several circulating or placenta-related ncRNAs has been linked to insulin resistance and β-cell dysfunction, the key pathophysiological features of GDM. Furthermore, significant associations between altered ncRNA profiles and GDM-related complications, such as macrosomia or trophoblast dysfunction, have been observed. Remarkably, the deregulation of ncRNAs, which might be linked to a detrimental intrauterine environment, can lead to changes in the expression of target genes in the offspring, possibly contributing to the development of long-term GDM-related complications, such as metabolic and cardiovascular diseases. In this review, all the recent findings on ncRNAs and GDM are summarized, particularly focusing on the molecular aspects and the pathophysiological implications of this complex relationship.

Abstract
INTRODUCTION There is evidence that cigarette smoking participates in disease progression through endothelial apoptosis. Bcl-2 family proteins are essential and critical regulators of apoptosis. We explored whether Bcl-2 plays a role in cigarette smoke extract induced (CSE-induced) endothelial apoptosis. Furthermore, given the involvement of epigenetics in apoptosis and Bcl-2 expression, we hypothesized that CSE-induced apoptosis might be caused by gene methylation. METHODS Human umbilical vascular endothelial cells (HUVECs) were treated with CSE, CSE plus 5-aza-2'-deoxycytidine (AZA, an inhibitor of DNA methylation), or AZA and phosphate-buffered saline (PBS). Endothelial apoptosis was determined by Annexin-V and propidium iodide staining. The expression levels of Bcl-2, Bax, and cytochrome C (cyt C) were assessed by immunoblotting and RT-PCR. The methylation status of the Bcl-2 promoter was observed by bisulfite sequencing PCR (BSP). RESULTS The apoptotic index of endothelial cells in the CSE-treated group increased. Decreased expression of Bcl-2 and high methylation of the Bcl-2 promoter were observed after CSE treatment. AZA alleviated the endothelial apoptosis caused by CSE. AZA treatment also increased Bcl-2 expression along with decreased Bcl-2 promoter methylation. CONCLUSIONS Inhibiting DNA methylation alleviates CSE-induced endothelial apoptosis and Bcl-2 promoter methylation. Bcl-2 promoter methylation might be involved in CES-induced endothelial apoptosis.

Abstract
BACKGROUND AND AIMS Non-O blood type (BT) is a risk factor for thromboses, which has been attributed to its effects on von Willebrand factor (VWF)/factor VIII (FVIII) levels. Although high VWF/FVIII may be risk factors for portal vein thrombosis (PVT) in patients with advanced chronic liver disease (ACLD), the impact of BT on PVT is unknown. We aimed to assess (I) whether non-O-BT is a risk factor for PVT and (II) whether non-O-BT impacts VWF/factor VIII in patients with ACLD. METHODS Retrospective analysis comprising two cohorts: (I) "US" including all adult liver transplantations in the US in the MELD era and (II) "Vienna" comprising patients with a hepatic venous pressure gradient (HVPG) ≥6 mmHg. RESULTS (I) The "US cohort" included 84 947 patients (non-O: 55.43%). The prevalence of PVT at the time of listing (4.37% vs 4.56%; P = .1762) and at liver transplantation (9.56% vs 9.33%; P = .2546) was similar in patients with O- and non-O-BT. (II) 411 patients were included in the "Vienna cohort" (non-O: 64%). Mean HVPG was 18(9) mmHg and 90% had an HVPG ≥10 mmHg. Patients with non-O-BT had slightly increased VWF levels (318(164)% vs 309(176)%; P = .048; increase of 23.8%-23.9% in adjusted analyses), but this difference was driven by patients with less advanced disease. However, non-O-BT explained only 1% of the variation in VWF and had no effect on FVIII. CONCLUSIONS Although non-O-BT impacts VWF in patients with early stage ACLD, its contribution to VWF variation is considerably smaller than in the general population. Moreover, non-O-BT had no impact on FVIII. These findings may explain the absence of an association between non-O-BT and PVT in patients with advanced cirrhosis.

Abstract
BACKGROUND The ratio of von Willebrand Factor to platelets (VITRO) reflects the severity of fibrosis and portal hypertension and might thus hold prognostic value. METHODS Patients with compensated cirrhosis were recruited. VITRO, Child-Pugh score (CPS) and MELD were determined at study entry. Hepatic decompensation was defined as variceal bleeding, ascites or hepatic encephalopathy. Liver transplantation and death were recorded. RESULTS One hundred and ninety-four patients with compensated cirrhosis (CPS-A 89%, B 11%; 56% male; median age 56 years; 50% with varices) were included. During a median follow-up of 45 months (IQR 29-61), decompensation occurred in 35 (18%) patients and 14 (7%) patients deceased. The risk of hepatic decompensation was significantly increased in the n = 88 (45%) patients with a VITRO ≥ 2.5 (p < 0.001). Patients with a VITRO ≥ 2.5 had a higher probability of decompensation at 1-year 9% (95% CI 3-16) vs. 0% (95% CI 0-0) and at 2-years 18% (95% CI 10-27%), vs. 4% (95% CI 0-8%) as compared to patients with VITRO < 2.5. Patients with VITRO ≥ 2.5, the estimated 1-year/2-year survival rates were at 98% (95% CI 95-100%) and 94% (95% CI 88-99%) as compared to 100% (95% CI 100-100%) both in the patients with a VITRO < 2.5 (p < 0.001). After adjusting for age, albumin and MELD, VITRO ≥ 2.5 remained as significant predictor of transplant-free mortality (HR 1.38, CI 1.09-1.76; p = 0.007). Patients with compensated cirrhosis and VITRO > 2.1 after hepatitis C eradication remained at significantly increased risk for decompensation (p = 0.033). CONCLUSIONS VITRO is a valuable prognostic tool for estimating the risk of decompensation and mortality in patients with compensated cirrhosis-including the setting after hepatitis C eradication.

Abstract
BACKGROUND AND AIM Cirrhotic patients with gastroesophageal varices and non-tumoral portal vein thrombosis have a higher risk of re-bleeding and poor prognosis. This study aimed to analyze inflammatory biomarkers and thromboelastography in cirrhotic patients with portal vein thrombosis. METHODS A total of 385 consecutive cirrhotic patients with gastroesophageal varices were prospectively enrolled between 1 December 2016, and 31 August 2017. Of these, 231 were eligible for analysis and were divided into portal vein thrombosis (n = 103) and non-portal vein thrombosis (n = 128) groups based on computerized tomography angiography findings. RESULTS Patients with portal vein thrombosis generally had higher Child-Pugh scores than those without portal vein thrombosis (6.38 ± 0.12 vs. 5.81 ± 0.09, P < 0.001). The serum albumin levels were significantly lower in patients with portal vein thrombosis (35.90 ± 0.52 vs. 38.52 ± 0.43, P < 0.001). The portal vein thrombosis group had significant higher serum levels of interleukin 6 [4.85 (3.15-6.99) vs. 3.09 (2.06-5.20) pg/ml, P < 0.001] and tumor necrosis factor alpha [10.70 (7.60-15.20) vs. 9.07 (7.03-11.60) pg/ml, P = 0.020]. The interleukin 6 level was 2.5-fold higher in patients with portal vein thrombosis (adjusted odds ratio: 2.574; 95% confidential interval: 1.248-5.310). Thromboelastography showed that TEG-R, the reaction time, was significantly lower in the portal vein thrombosis group [5.20 (4.80-6.30) vs. 6.00 (5.20-6.95), P = 0.009], indicating enhanced coagulation activity. CONCLUSION This study confirmed the important role of systemic inflammation in portal vein thrombosis. Interleukin 6, an important inflammatory cytokine, is independently associated with portal vein thrombosis. The correlation between the interleukin 6 level and portal vein thrombosis requires further investigation.

Abstract
Obesity is characterized by the excessive deposition of fat that may interfere with the normal metabolic process of the body. It is a chronic condition associated with various metabolic syndromes, whose prevalence is grossly increasing, and affects both children and adults. Accumulation of excessive macronutrients on the adipose tissues promotes the secretion and release of inflammatory mediators, including interleukin-6 (IL-6), interleukin 1β, tumor necrotic factor-α (TNF-α), leptin, and stimulation of monocyte chemoattractant protein-1 (MCP-1), which subsequently reduce the production of adiponectin thereby initiating a proinflammatory state. During obesity, adipose tissue synthesizes and releases a large number of hormones and cytokines that alter the metabolic processes, with a profound influence on endothelial dysfunction, a situation associated with the formation of atherosclerotic plaque. Endothelial cells respond to inflammation and stimulation of MCP-1, which is described as the activation of adhesion molecules leading to proliferation and transmigration of leukocytes, which facilitates their increase in atherogenic and thromboembolic potentials. Endothelial dysfunction forms the cornerstone of this discussion, as it has been considered as the initiator in the progression of cardiovascular diseases in obesity. Overexpression of proinflammatory cytokines with subsequent reduction of anti-inflammatory markers in obesity, is considered to be the link between obesity-induced inflammation and endothelial dysfunction. Inhibition of inflammatory mechanisms and management and control of obesity can assist in reducing the risks associated with cardiovascular complications.

Abstract
The gut microbiota influence host vascular physiology locally in the intestine, but also evoke remote effects that impact distant organ functions. Amongst others, the microbiota affect intestinal vascular remodeling, lymphatic development, cardiac output and vascular function, myelopoiesis, prothrombotic platelet function, and immunovigilance of the host. Experimentally, host-microbiota interactions are investigated by working with animals devoid of symbiotic bacteria, i.e., by the decimation of gut commensals by antibiotic administration, or by taking advantage of germ-free mouse isolator technology. Remarkably, some of the vascular effects that were unraveled following antibiotic treatment were not observed in the germ-free animal models and vice versa. In this review, we will dissect the manifold influences that antibiotics have on the cardiovascular system and their effects on thromboinflammation.

Abstract
The intimate connection and the strict mutual cooperation between the gut and the liver realizes a functional entity called gut-liver axis. The integrity of intestinal barrier is crucial for the maintenance of liver homeostasis. In this mutual relationship, the liver acts as a second firewall towards potentially harmful substances translocated from the gut, and is, in turn, is implicated in the regulation of the barrier. Increasing evidence has highlighted the relevance of increased intestinal permeability and consequent bacterial translocation in the development of liver damage. In particular, in patients with non-alcoholic fatty liver disease recent hypotheses are considering intestinal permeability impairment, diet and gut dysbiosis as the primary pathogenic trigger. In advanced liver disease, intestinal permeability is enhanced by portal hypertension. The clinical consequence is an increased bacterial translocation that further worsens liver damage. Furthermore, this pathogenic mechanism is implicated in most of liver cirrhosis complications, such as spontaneous bacterial peritonitis, hepatorenal syndrome, portal vein thrombosis, hepatic encephalopathy, and hepatocellular carcinoma. After liver transplantation, the decrease in portal pressure should determine beneficial effects on the gut-liver axis, although are incompletely understood data on the modifications of the intestinal permeability and gut microbiota composition are still lacking. How the modulation of the intestinal permeability could prevent the initiation and progression of liver disease is still an uncovered area, which deserves further attention.

Abstract
Portal vein thrombosis (PVT) represents a well-known complication during the natural course of liver cirrhosis (LC), ranging from asymptomatic cases to life-threating conditions related to portal hypertension and hepatic decompensation. Portal flow stasis, complex acquired hypercoagulable disorders and exogenous factors leading to endothelial dysfunction have emerged as key factors for PVT development. However, PVT occurrence remains unpredictable and many issues regarding its natural history, prognostic significance and treatment are still elusive. In particular although spontaneous resolution or disease stability occur in most cases of PVT, factors predisposing to disease progression or recurrence after spontaneous recanalization are not clarified as yet. Moreover, PVT impact on LC outcome is still debated, as PVT may represent itself a consequence of liver fibrosis and hepatic dysfunction progression. Anticoagulation and transjugular intrahepatic portosystemic shunt are considered safe and effective in this setting and are recommended in selected cases, even if the safer therapeutic option and the optimal therapy duration are still unknown. Nevertheless, their impact on mortality rates should be addressed more extensively. In this review we present the most debated questions regarding PVT, whose answers should come from prospective cohort studies and large sample-size randomized trials.

Abstract
Introduction: There is emerging evidence linking the commensal gut microbiota with the development of cardiovascular disease and arterial thrombosis. In immunothrombosis, the host clotting system protects against the dissemination of invading microbes, not considering the huge number of microbes that interact with host physiology in a mutualistic fashion. Areas covered: Interestingly, recent research revealed that colonizing gut microbes profoundly influence host innate immune pathways that support arterial thrombus growth. The gut microbiota promotes arterial thrombus formation by enhancing the pro-adhesive capacity of the vascular endothelium, triggering hepatic von Willebrand factor synthesis and its release by Weibel-Palade body exocytosis, resulting in elevated von Willebrand factor levels and enhancing FVIII stability in plasma. Furthermore, the metabolic capacity of gut resident microbes promotes agonist-induced platelet activation and deposition. Here, we give an overview, with a focus on the vascular endothelium, on how this gut-resident microbial ecosystem contributes to arterial thrombus formation. Expert opinion: The gut microbiota and its metabolites not only act on agonist-induced platelet reactivity, but also influence the hepatic endothelial phenotype via remote signaling, facilitating arterial thrombus growth at the arterial injury site.

Abstract
Portal vein thrombosis unrelated to solid malignancy is common in patients with cirrhosis, but less frequently observed in patients without cirrhosis. Prompt diagnosis and management of acute symptomatic portal vein thrombosis are essential. Failure to detect and treat thromboses can result in mesenteric ischemia, chronic cavernous transformation, and complications of portal hypertension. In patients with cirrhosis, development of portal vein thrombosis is often insidious and remains undetected until its incidental detection. Management of portal vein thrombosis in patients with cirrhosis is more controversial. However, there are data to support treatment of specific patients with anticoagulation agents. We review the common and distinct features of portal vein thromboses in patients without liver tumors, with and without cirrhosis.

Abstract
Portal vein thrombosis (PVT) in patients with liver cirrhosis is a common complication associated with adverse outcomes. Aim. To build a predictive model for PVT in cirrhotic patients. Materials and methods. A single centre case-control study was carried out. From the database of 1512 cirrhotic patients 94 with newly diagnosed PVT based on contrast-enhanced computed tomography were referred to the Case group. Malignant PVT was an exclusion criterion. Patients without PVT were stratified and matched according to sex, age and etiology of cirrhosis; case-control ratio was 1 : 3-4. The prevalence of PVT in the database, clinical, laboratory, instrumental parameters of the groups were evaluated. Logistic regression model was used to estimate association between variables and PVT. Results and discussion. The overall prevalence of PVT was 6.2% with the highest rates among the patients with HBV infection - 16.7%, nonalcoholic steatohepatitis - 15.6%, alcohol abuse in combination with HCV infection - 11.7%. The best predictive model included variables: Child-Pugh classes B-C (coefficient of regression β=1.853, р=0.001), ascites (β=0.460, р=0.003), hepatocellular carcinoma without vascular invasion (β=2.126, р=0.0001), endoscopic band ligation (β=0.774, р=0.003), azygoportal disconnection (β=2.734, р=0.001), portal hypertensive gastropathy (β=0.793, р=0.017), portal vein diameter (β=0.203, р=0.004), and local factors - ulcerative colitis flare, Clostridium difficile enterocolitis, spontaneous bacterial peritonitis, colorectal cancer, splenectomy, cholecystectomy (β=2.075, р=0.017). The model had accuracy 85.8% (95% CI 81.7-89.4%), sensitivity - 55.1% (95% CI 43.4-66.4%), specificity - 95% (95% CI 91.6-97.3%), and AUC - 0.871 (95% CI 0.826-0.916). Conclusion. Child-Pugh classes B-C, severe portal hypertension, hepatocellular carcinoma without vascular invasion, and local factors were estimated as risk factors of PVT in cirrhotic patients.

Abstract
The transcription factor NF-κB is a central mediator of inflammation with multiple links to thrombotic processes. In this review, we focus on the role of NF-κB signaling in cell types within the vasculature and the circulation that are involved in thrombo-inflammatory processes. All these cells express NF-κB, which mediates important functions in cellular interactions, cell survival and differentiation, as well as expression of cytokines, chemokines, and coagulation factors. Even platelets, as anucleated cells, contain NF-κB family members and their corresponding signaling molecules, which are involved in platelet activation, as well as secondary feedback circuits. The response of endothelial cells to inflammation and NF-κB activation is characterized by the induction of adhesion molecules promoting binding and transmigration of leukocytes, while simultaneously increasing their thrombogenic potential. Paracrine signaling from endothelial cells activates NF-κB in vascular smooth muscle cells and causes a phenotypic switch to a “synthetic” state associated with a decrease in contractile proteins. Monocytes react to inflammatory situations with enforced expression of tissue factor and after differentiation to macrophages with altered polarization. Neutrophils respond with an extension of their life span—and upon full activation they can expel their DNA thereby forming so-called neutrophil extracellular traps (NETs), which exert antibacterial functions, but also induce a strong coagulatory response. This may cause formation of microthrombi that are important for the immobilization of pathogens, a process designated as immunothrombosis. However, deregulation of the complex cellular links between inflammation and thrombosis by unrestrained NET formation or the loss of the endothelial layer due to mechanical rupture or erosion can result in rapid activation and aggregation of platelets and the manifestation of thrombo-inflammatory diseases. Sepsis is an important example of such a disorder caused by a dysregulated host response to infection finally leading to severe coagulopathies. NF-κB is critically involved in these pathophysiological processes as it induces both inflammatory and thrombotic responses.

Abstract
OBJECTIVE This study was designed to investigate whether the mice treated with triptolide (TP) could disrupt the liver immune homeostasis, resulting in the inability of the liver to eliminate the harmful response induced by lipopolysaccharide (LPS). In addition, we explored whether apoptosis and necroptosis played a critical role in the progression of the hepatotoxicity induced by TP-LPS co-treatment. METHODS Female C57BL/6 mice were continuously administrated with two different doses of TP (250 μg/kg and 500 μg/kg) intragastrically for 7 days. Subsequently, a single dose of LPS (0.1 mg/kg) was injected intraperitoneally to testify whether the liver possesses the normal immune function to detoxicate the exogenous pathogen's stimulation. To prove the involvement of apoptosis and necroptosis in the liver damage induced by TP-LPS co-treatment, apoptosis inhibitor Z-VAD-FMK (FMK) and necroptosis inhibitor necrostatin (Nec-1) were applied before the stimulation of LPS to diminish the apoptosis and necroptosis respectively. RESULTS TP or LPS alone did not induce significant liver damage. However, compared with TP or LPS treated mice, TP-LPS co-treatment mice showed obvious hepatotoxicity with a remarkable elevation of serum ALT and AST accompanied by abnormal bile acid metabolism, a depletion of liver glycogen storage, aberrant glucose metabolism, an up-regulation of inflammatory cell infiltration, and an increase of apoptosis and necroptosis. Intraperitoneal injection of FMK or Nec-1 could counteract the toxic reactions induced by TP-LPS co-treatment. CONCLUSION TP could disrupt the immune response, resulting in hypersensitivity of the liver upon LPS stimulation, ultimately leading to abnormal liver function and cell death. Additionally, apoptosis and necroptosis played a vital role in the development of liver damage induced by TP-LPS co-treatment.

We aimed to measure plasma LPS concentration using a new method of direct quantification of 3-hydroxymyristate (3-HM), a lipid component of LPS, and to evaluate correlations between 3-HM and markers of liver function, endothelial activation, portal hypertension and enterocyte damage. METHODS Plasma from 90 noninfected cirrhotic patients (30 Child-Pugh [CP]-A, 30 CP-B, 30 CP-C) was prospectively collected. The concentration of 3-HM was determined by high-performance liquid chromatography coupled with mass spectrometry. RESULTS 3-HM levels were higher in CP-C patients (CP-A/CP-B/CP-C: 68/70/103 ng/mL, P = 0.005). Patients with severe acute alcoholic hepatitis (n = 16; 113 vs 74 ng/mL, P = 0.012), diabetic patients (n = 22; 99 vs 70 ng/mL, P = 0.028) and those not receiving beta blockers (n = 44; 98 vs 72 ng/mL, P = 0.034) had higher levels of 3-HM. We observed a trend towards higher baseline levels of 3-HM in patients with hepatic encephalopathy (n = 7; 144 vs 76 ng/mL, P = 0.45) or SIRS (n = 10; 106 vs 75 ng/mL, P = 0.114). In multivariate analysis, high levels of 3-HM were associated with CP (OR = 4.39; 95%CI = 1.79-10.76) or MELD (OR = 8.24; 95%CI = 3.19-21.32) scores. Patients dying from liver insufficiency (n = 6) during a 12-month follow-up had higher baseline levels of 3-HM (106 vs 75 ng/mL, P = 0.089). CONCLUSIONS In noninfected cirrhotic patients, 3-HM arises more frequently with impairment of liver function, heavy alcohol consumption, diabetic status, nonuse of beta blockers and a trend towards poorer outcome is also observed. The direct mass measurement of LPS using 3-HM appears reliable to detect transient endotoxaemia and promising to manage the follow-up of cirrhotic patients.

Abstract
Portal vein thrombosis (PVT) is a frequent and serious complication in patients with liver cirrhosis (LC). Recently, a new classification of PVT was proposed, although the functional component was not completed included. The status of liver disease (compensated/decompensated) should be added to this classification. Reduced portal flow velocity and the acquired hypercoagulable status associated with LC are the main risk factors for PVT development, although endothelial dysfunction may play an important role that needs to be further evaluated. The European Association for the Study of the Liver and the American Association for the Study of Liver Disease recommend that the anticoagulant treatment should be consider in cirrhotic patients with PVT. Low molecular weight heparin and vitamin K antagonists proved their efficacy and relatively safety in PVT treatment, although in addition to recanalization rates, more complex end-points such as mortality and decompensation rate should be evaluated. The new oral anticoagulant therapies offers the advantage of oral administration in the absence of laboratory monitoring, however, there are a few reports regarding their use in cirrhotic patients, most of them referring to compensated isolated cases. Transjugular intrahepatic portosystemic shunt could be an alternative if thrombosis progresses despite anticoagulatant therapy and/or when PVT is associated with portal hypertension complications. The aim of this editorial is to discuss the different aspects of pathophysiology, clinical relevance, diagnosis and management of PVT in patients with LC.

Abstract
Patients with advanced liver disease have traditionally been considered at risk for bleeding complications. However, although bleeding in patients with cirrhosis frequently occurs due to complications of portal hypertension, research performed within the last 15 years has increasingly shown that hemostasis in patients with liver failure generally achieves a state of "rebalance", whereby compensatory systems restore a relatively neutral or even slightly pro-thrombotic state. Much recent clinical and in vitro research has, in fact, shown over-compensation, such that patients with acute and stable chronic liver failure may have a thrombotic tendency, which may participate in the progression of liver disease and cause systemic and portal thrombosis. Investigators have started to identify differences in hemostasis in patients with unstable cirrhosis, the newly defined syndrome of acute-on-chronic liver failure (ACLF), compared to those with stable cirrhosis. The following discussion will summarize much of the background of rebalanced hemostasis in patients with cirrhosis and acute liver failure (ALF), and suggest management algorithms for coagulation abnormalities before invasive procedures, during active bleeding, and for prophylaxis and treatment of thrombotic complications.

Abstract
Fibrosis is the main consequence of any kind of chronic liver damage. Coagulation and thrombin generation are crucial in the physiological response to tissue injury; however, the inappropriate and uncontrolled activation of coagulation cascade may lead to fibrosis development due to the involvement of several cellular types and biochemical pathways in response to thrombin generation. In the liver, hepatic stellate cells and sinusoidal endothelial cells orchestrate fibrogenic response to chronic damage. Thrombin interacts with these cytotypes mainly through protease-activated receptors (PARs), which are expressed by endothelium, platelets and hepatic stellate cells. This review focuses on the impact of coagulation in liver fibrogenesis, describes receptors and pathways involved and explores the potential antifibrotic properties of drugs active in hemostasis in studies with cells, animal models of liver damage and humans.

Abstract
Background
There is an unstable balance between pro- and anti-haemostatic processes in patients with cirrhosis. We hypothesized, that in patients with acute decompensation (AD) the major alterations of von Willebrand factor (VWF) could contribute to the pro-thrombotic situation as compared to patients with stable (ST) cirrhosis.
Patients and Methods
We analysed different parameters of VWF, including detailed multimer distribution by densitometry and platelet adhesion, together with

(ADAMTS13) activity and antigen and C-reactive protein (CRP) levels in patients with ST cirrhosis (
n
= 99), with AD (
n
= 54) and controls (
n
= 92).
Results
VWF antigen, ristocetin co-factor as well as collagen-binding activities were elevated in both cirrhotic groups in a stepwise manner. There was a decrease in high and an increase in low molecular weight multimer ratios in the majority of ST cirrhosis. However, in 24 out of 54 AD patients, ultra-large VWF multimers (ultra-large molecular weight multimers [ULMWM]) were found. ADAMTS13 activity in ST and AD patients without ULMWM was similar to controls (median [interquartile range; IQR]%: 98 [67–132] and 91 [60–110] vs. 106 [88–117], respectively). The presence of ULMWM in AD patients was associated with low ADAMTS13 activity [33 (24–49)%] and high CRP level [23 (7.1–83.6) mg/L]. Adhesion of normal platelets showed a stepwise increase in the presence of cirrhotic plasmas, reaching the highest level in AD patients with ULMWM.
Conclusion
Characteristic changes of VWF parameters are seen in ST cirrhosis. In AD patients, highly increased VWF and reduced ADAMTS13 activity could be found, along with the presence of ULMWM, which are possible markers and contributors of the disease progression.
