Abstract
Portal vein thrombosis (PVT) refers to the development of a non-malignant obstruction of the portal vein, its branches, its radicles, or a combination. This Review first provides a comprehensive overview of all aspects of PVT, namely the specifics of the portal venous system, the risk factors for PVT, the pathophysiology of portal hypertension in PVT, the interest in non-invasive tests, as well as therapeutic approaches including the effect of treating risk factors for PVT or cause of cirrhosis, anticoagulation, portal vein recanalisation by interventional radiology, and prevention and management of variceal bleeding in patients with PVT. Specific issues are also addressed including portal cholangiopathy, mesenteric ischaemia and intestinal necrosis, quality of life, fertility, contraception and pregnancy, and PVT in children. This Review will then present endpoints for future clinical studies in PVT, both in patients with and without cirrhosis, agreed by a large panel of experts through a Delphi consensus process. These endpoints include classification of portal vein thrombus extension, classification of PVT evolution, timing of assessment of PVT, and global endpoints for studies on PVT including clinical outcomes. These endpoints will help homogenise studies on PVT and thus facilitate reporting, comparison between studies, and validation of future studies and trials on PVT.

Abstract
Background and Aims Hypoalbuminemia, as defined by serum albumin (SA) levels ≤35 g/L, is associated to venous and arterial thrombosis in general population and in patients at risk of cardiovascular disease. It is unknown if SA ≤35 g/L is also associated to portal vein thrombosis (PVT) in cirrhosis. Methods Cirrhotic patients enrolled in the Portal vein thrombosis Relevance On Liver cirrhosis: Italian Venous thrombotic Events Registry (PRO-LIVER) study (n = 753), were followed-up for 2 years to assess the risk of PVT, that was diagnosed by Doppler ultrasonography. Child-Pugh classes, Model for End-Stage Liver Disease score, presence of hepatocellular carcinoma and laboratory variables including SA, D-dimer, and high-sensitivity C-reactive protein (hs-CRP) were measured at baseline. Results SA ≤35 g/L was detected in 52% of patients. A logistic multivariate regression analysis showed that higher Child-Pugh class, hepatocellular carcinoma and thrombocytopenia were significantly associated to SA ≤35 g/L. In a subgroup of patients where data regarding hs-CRP and D-dimer were available, SA ≤35 g/L was inversely associated with hs-CRP and D-dimer. During the follow-up, a total of 61 patients experienced PVT. A Kaplan Meier survival analysis showed SA ≤35 g/L was associated to increased risk of PVT compared to SA >35 g/L (P = .005). A multivariate Cox proportional hazards regression analysis showed that male sex, lower platelet count, and SA ≤35 g/L remained associated to PVT after adjusting for confounding factors. Conclusion Cirrhotic patients with SA ≤35 g/L are at higher risk of experiencing PVT compared to those with SA >35 g/L and could be considered as potential candidates to anticoagulant prophylaxis for PVT prevention.

Abstract
OBJECTIVE The purpose of this study was to determine how thromboelastography (TEG) parameters differ by various clinical conditions that commonly occur in patients with cirrhosis, including sepsis, acute on chronic liver failure (ACLF), alcohol-associated hepatitis (AAH) and portal vein thrombosis (PVT). BACKGROUND TEG, a whole blood assay, is used to assess several parameters of coagulation and is becoming increasingly used in clinical practice. STUDY This study was a retrospective chart review of 155 patients admitted to the ICU with decompensated cirrhosis from 2017 to 2019. RESULTS The R time was significantly shorter in patients when they were septic compared to when they were not and longer in patients with vs. without ACLF grade 3. Alpha angle and maximum amplitude was decreased in patients with severe AAH compared to those without severe AAH; and maximum amplitude was increased in patients with acute PVT compared to those with chronic PVT. R time was positively correlated with Chronic Liver Failure Consortium Organ Failure and Chronic Liver Failure Consortium ACLF scores (rho = 0.22, P = 0.020), while alpha angle and maximum amplitude were negatively correlated with MELD-NA. CONCLUSION Findings suggest TEG parameters vary in several clinical conditions in patients with decompensated cirrhosis who are admitted to the ICU. Prospective research is needed to confirm our findings and to determine how this knowledge can be used to guide clinical practice, as well as blood product transfusions in the setting of bleeding or prior to invasive procedures.

Abstract
BACKGROUND Portal vein thrombosis (PVT) is a significant issue in cirrhotic patients, necessitating early detection. This study aims to develop a data-driven predictive model for PVT diagnosis in chronic hepatitis liver cirrhosis patients. METHODS We employed data from a total of 816 chronic cirrhosis patients with PVT, divided into the Lanzhou cohort (n = 468) for training and the Jilin cohort (n = 348) for validation. This dataset encompassed a wide range of variables, including general characteristics, blood parameters, ultrasonography findings and cirrhosis grading. To build our predictive model, we employed a sophisticated stacking approach, which included Support Vector Machine (SVM), Naïve Bayes and Quadratic Discriminant Analysis (QDA). RESULTS In the Lanzhou cohort, SVM and Naïve Bayes classifiers effectively classified PVT cases from non-PVT cases, among the top features of which seven were shared: Portal Velocity (PV), Prothrombin Time (PT), Portal Vein Diameter (PVD), Prothrombin Time Activity (PTA), Activated Partial Thromboplastin Time (APTT), age and Child-Pugh score (CPS). The QDA model, trained based on the seven shared features on the Lanzhou cohort and validated on the Jilin cohort, demonstrated significant differentiation between PVT and non-PVT cases (AUROC = 0.73 and AUROC = 0.86, respectively). Subsequently, comparative analysis showed that our QDA model outperformed several other machine learning methods. CONCLUSION Our study presents a comprehensive data-driven model for PVT diagnosis in cirrhotic patients, enhancing clinical decision-making. The SVM-Naïve Bayes-QDA model offers a precise approach to managing PVT in this population.

Abstract
Purpose This study aimed to explore inflammatory biomarkers, stool's functional bacterial groups and their possible link to portal vein thrombosis (PVT) in patients with liver cirrhosis (LC). Materials and Methods An observational study of 300 participants: 200 inhospital cirrhotic patients, who met inclusion criteria, equally assigned into two groups, based on the presence or absence of PVT and 100 healthy controls was carried out. Results The PVT group displayed significant differences related to older age, cigarettes smoking history, emergency admission, higher Child-Pugh score, metabolic related disorders and nonalcoholic fatty liver disease, as well as non-obstructive aspects, with chronic thrombi. The PVT group exhibited significant differences related to biomarkers such as tumor necrosis factor (TNF)-alpha, C-reactive protein (CRP), D-dimers (D-D), as well as gut overall dysbiosis (DB) and alteration of different functional bacterial groups of the gut microbiota. Strong positive correlations were observed between PVT severity, and TNF-alpha, CRP, D-D as well as lipopolysaccharide (LPS) positive bacteria. Esophageal varices, age and abdominal pain were independent predictors for PVT severity as well as CRP, TNF-alpha and D-D. Conclusion Patients with LC and PVT displayed elevation of TNF-alpha, CRP, D-D alterations of the functional gut microbiota, as well as several morphological and clinical particularities. Although the LPS positive gut microbiota was linked to inflammatory biomarkers and PVT severity, it was not proven to be an independent predictor of the PVT severity like CRP, TNF-alpha and D-D.

Abstract
Viscoelastic tests, specifically thromboelastography and rotational thromboelastometry, are increasingly being used in the management of postoperative bleeding in surgical intensive care units (ICUs). However, life-threatening bleeds may complicate the clinical course of many patients admitted to medical ICUs, especially those with underlying liver dysfunction. Patients with cirrhosis have multiple coagulation abnormalities that can lead to bleeding or thrombotic complications. Compared to conventional coagulation tests, a comprehensive depiction of the coagulation process and point-of-care availability are advantages favoring these devices, which may aid physicians in making a rapid diagnosis and instituting early interventions. These tests may help predict bleeding and rationalize the use of blood products in these patients.

Abstract
BACKGROUND AND AIMS To investigate the usefulness of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), protein C (PC), and thromboelastography (TEG) to serve as a predictor of portal vein thrombosis (PVT) in patients with liver cirrhosis. Additionally, we examined the clinical significance of the above indicators in terms of disease progression. METHODS A total of 123 patients with liver cirrhosis were recruited from May 2021 to December 2021, according to the imaging findings. They were divided into the PVT group (n = 52) and the non-PVT group (n = 71). Furthermore, patients with PVT were divided into plasma transfusion groups (n = 13) and non-plasma transfusion groups (n = 39). The basic general information, past medical history, laboratory, and imaging examination data were collected and analyzed. RESULTS In univariate analysis, there was no significant difference between the two groups in IL-6, PC, reaction time (R), alpha angle (Angle), maximum amplitude, or coagulation index (CI) (P > 0.05). TNF-α in the PVT group was significantly lower than that in the non-PVT group (P = 0.001). K-time (K) in the PVT group was significantly higher than that in the non-PVT group (P = 0.031). There was no significant difference in IL-6, TNF-α, PC, or TEG between different Child-Pugh classification groups (P > 0.05). There were no significant differences in TEG between the plasma transfusion group and the non-plasma transfusion group. In Binary logistic regression analysis, TNF-α (OR = 0.9881, 95%CI = 0.971, 0.990, P < 0.001), K(OR = 1.28, 95% = 1.053, 1.569, P = 0.014), activate partial thromboplastin time (APTT) (OR = 0.753, 95%CI = 0.656, 0.865, P < 0.001), portal vein diameter (OR = 1.310, 95%CI = 1.108, 1.549, P = 0.002)and the history of splenectomy or embolism (OR = 7.565, 95%CI = 1.514, 37.799, P = 0.014)were related to the formation of PVT. CONCLUSIONS TNF-α, K, APTT, portal vein diameter, and splenectomy or embolism history were associated with PVT formation, but IL-6 was not.

Abstract
BACKGROUND AND AIM Portal hypertension is a common complication of chronic liver diseases responsible for most liver cirrhosis consequences. In patients with portal hypertension, oesophagogastric variceal bleeding is a leading cause of death. Most research has focused on high-risk gastroesophageal varices and bleeding, with only a few studies on early varices. However, early intervention of gastroesophageal varices was found to better improve the prognosis and reduce mortality, but there is still no relevant research. Ultrasonic endoscopy is a combination of endoscopy and ultrasonic imaging. It can gastroscopically detect varices around the oesophagus and stomach and detect oesophageal collateral veins and perforating veins earlier, which is helpful for the early diagnosis of varices. Therefore, this study aimed to explore the correlation between serum fibrosis markers and early gastroesophageal varices in compensated cirrhosis patients. METHODS This study included 791 patients with compensated cirrhosis. The selected patients were categorized into three groups. The early gastroesophageal varices group included patients with gastroesophageal varices found by endoscopic ultrasonography but not by gastroscopy. The no gastroesophageal varices group underwent endoscopic ultrasonography and gastroscopy without varices. In addition, gastroesophageal varices can be detected with both techniques. Multiple logistic regression analysis explored the association of serum fibrosis markers with early gastroesophageal varices. RESULTS Among the 791 compensated liver cirrhosis patients, 198 patients were without gastroesophageal varices, 279 patients had early gastroesophageal varices, 314 patients had gastroesophageal varices, and both techniques could detect varices. There was a positive correlation between serum fibrosis markers and early gastroesophageal varices. In univariate logistic regression analysis, the patients with early gastroesophageal varices had lower platelet counts (P = 0.034) and higher aspartate aminotransferase (P = 0.046), total bilirubin (P = 0.041), hyaluronic acid (P < 0.001), laminin (P < 0.001), type III procollagen (P = 0.005), type IV collagen (P = 0.002), liver stiffness measurement (P = 0.001), APRI (P = 0.019) and FIB-4 (P = 0.002). Multivariate analysis showed that laminin (OR 1.011; 95% CI 1.004-1.017, P = 0.001) was an independent risk factor for predicting early gastroesophageal varices in compensated cirrhosis patients. CONCLUSION Higher laminin was independently associated with early gastroesophageal varices in compensated cirrhosis patients.

Portal vein thrombosis associates with high platelet-fibrin clot strength and platelet activation in decompensated cirrhosis: A retrospective study. Dig Liver Dis 2022; 55:629-636. [PMID: 36280436 DOI: 10.1016/j.dld.2022.09.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 09/17/2022] [Accepted: 09/30/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND AND AIMS Alteration of platelet status associates with decompensation and death in cirrhosis, while its effect on portal vein thrombosis (PVT) remains unclear. We aimed to retrospectively investigate whether PVT associates with platelet-fibrin clot strength and platelet activation in decompensated cirrhosis. METHODS Platelet-fibrin clot strength (G) was measured by thromboelastography (TEG). Platelet activation was reflected by plasma concentrations of soluble p-selectin (sPs) and a platelet aggregation test adjusted for platelet counts. RESULTS Among 166 patients, 45 had PVT. The platelet count was significantly lower in PVT. While the G value was positively correlated with platelet count (ρ = 0.74, P < 0.01), increased G was associated with PVT after adjusting for platelet count in the logistic regression (P = 0.04). The normalized G value according to the linear relation with platelet count was calculated as follows: Gplatelet = [(G - 2622)/platelet count]. This coefficient had no correlation with platelet count and was an independent risk factor of PVT (OR = 1.03, CI95%: 1.01-1.05, P = 0.012). In two subanalyses, the collagen-induced platelet aggregation (n = 37, P = 0.029) and plasma concentration of sPs (n = 56, P = 0.001) adjusted for platelet count were significantly higher in PVT. CONCLUSION This study showed a positive correlation of high platelet-fibrin clot strength detected via TEG and platelet activation with PVT in decompensated cirrhosis.

Abstract
BACKGROUND Portal vein thrombosis (PVT) may be associated with negative outcomes in patients with liver cirrhosis. However, the prevalence and incidence of PVT in liver cirrhosis are heterogeneous among studies and have not been sufficiently determined yet. METHODS The PubMed, EMBASE, and Cochrane Library databases were searched. Eligible studies would explore the prevalence and/or incidence of PVT in liver cirrhosis without hepatocellular carcinoma or abdominal surgery. Pooled proportion with 95% confidence interval (CI) was calculated using a random-effect model. Factors associated with the presence/occurrence of PVT were also extracted. RESULTS Among the 8549 papers initially identified, 74 were included. Fifty-four studies explored the prevalence of PVT in liver cirrhosis with a pooled prevalence of 13.92% (95%CI=11.18-16.91%). Based on cross-sectional data, Child-Pugh class B/C, higher D-dimer, ascites, and use of non-selective beta-blockers (NSBBs) were associated with the presence of PVT in liver cirrhosis. Twenty-three studies explored the incidence of PVT in liver cirrhosis with a pooled incidence of 10.42% (95%CI=8.16-12.92%). Based on cohort data, Child-Pugh class B/C, higher model of end-stage liver disease score, higher D-dimer, lower platelets count, decreased portal flow velocity, ascites, use of NSBBs, and moderate or high-risk esophageal varices could predict the occurrence of PVT in liver cirrhosis. CONCLUSION Approximately one seventh of cirrhotic patients have PVT, and one tenth will develop PVT. Progression of liver cirrhosis and portal hypertension seems to be in parallel with the risk of PVT. Prospective studies with detailed information about classification and extension of PVT in liver cirrhosis are needed.

Abstract
OBJECTIVES Variceal hemorrhage is a fatal complication of cirrhosis. In this study, we aimed to investigate the role of serum interleukin 2 receptor (sIL-2R) as a predictive indicator in patients with a previous history of cirrhosis-related variceal bleeding. METHODS A total of 340 cirrhotic patients who had experienced variceal bleeding from December 2016 to December 2018 were enrolled, and were randomly assigned to the modeling group and the validation group. The 3-year variceal rebleeding rate and other outcomes including adverse events were analyzed between patients with different sIL-2R levels. RESULTS A time-dependent receiver operating characteristic (ROC) curve of variceal rebleeding indicated that sIL-2R had an area under the ROC curve (AUROC] of 0.731 and 0.837 for the modeling and validation groups, respectively, with a cut-off value of 426 U/mL. Kaplan-Meier analysis showed that higher sIL-2R level was related to an increased risk of variceal rebleeding rate (55.33% vs 24.34%, P = 0.024 and 51.28% vs 15.32%, P = 0.049) and decreased 3-year survival rate (91.16% vs 98.92%, P = 0.013 and 90.52% vs 97.50%, P = 0.180) in the modeling and validation groups. Elevated sIL-2R levels were associated with an increased risk of portal vein thrombosis and severe ascites as well as inferior liver function, hypercoagulable state, and increased portal pressure. CONCLUSION High sIL-2R levels were associated with poor prognosis in cirrhotic patients with previous variceal bleeding.

Abstract
BackgroundPortal vein thrombosis (PVT) is a serious complication of cirrhosis accompanied by unclear pathogenesis. Transforming growth factor-beta (TGF-β) has been implicated in atherosclerosis and venous thrombosis whereas study regarding its part in PVT is lacking. The aim of this study was to explore the role of cytokine TGF-β1 in PVT and the potential mechanism.Materials and methodsWe included patients with cirrhotic gastroesophageal varices and divided them into two groups according to the presence of PVT. Serum levels of TGF-β1 were detected using Cytometric Bead Array kit and compared between two groups. Coagulation status was assessed using thromboelastography (TEG). Primary liver sinusoidal endothelial cells were treated with TGF-β1 and evaluated for endothelial dysfunction by RT-PCR.ResultsOur results uncovered that TGF-β1 (6,866.55 vs. 3,840.60 pg/ml, P = 0.015) significantly increased in the PVT group. Splenectomy might promote PVT by increasing platelet-derived TGF-β1 levels. Other cytokines showed no difference between PVT and non-PVT groups. Besides, TGF-β1 was correlated with platelet, fibrinogen, TEG-CI, TEG-MA, and TEG-α (coef = 0.733, 0.494, 0.604, 0.608, and 0.511; P < 0.001, 0.027, 0.004, 0.004, and 0.021, respectively), which indicated a hypercoagulable state in PVT patients. RT-PCR of liver sinusoidal endothelial cells showed a markable increment of von Willebrand Factor (vWF), thrombomodulin(TM), intercellular adhesion moleclar-1(ICAM-1), and vascular endothelial growth factor(VEGF) after TGF-β1 treatment, suggesting the involvement of endothelial dysfunction.ConclusionElevated platelet-derived TGF-β1 exhibited association with hypercoagulability and promoting effect on endothelial dysfunction, closely related with PVT in cirrhotic patients.

Abstract
BACKGROUND Patients with liver diseases have complicated haemostatic alternations, resulting in both bleeding and thromboembolic complications, which cannot be sufficiently evaluated by conventional coagulation tests (CCTs), such as platelet count or prothrombin time. Thromboelastography (TEG) is a whole blood viscoelastic test which globally reflects changes in the haemostatic system, and its utility in evaluating patients with liver disease is increasingly recognised. AIMS To review the current evidence and clinical significance of TEG in liver diseases. METHODS Literature regarding TEG and liver diseases was comprehensively searched. RESULTS TEG is associated closely with the severity and aetiology of liver disease, the course of infection and the risk of bleeding and death, but not the risk of portal venous system thrombosis. Additionally, TEG-guided transfusion protocols can significantly decrease the requirement for blood products compared to those guided by CCTs. CONCLUSION TEG can reflect the haemostatic status of liver diseases more comprehensively than CCTs. It has the potential to assess the severity of liver diseases, predict the risk of bleeding and death in patients with liver disease and guide blood product transfusion. Future studies should standardise the use of TEG for assessing disease severity and development of clinical events and guiding blood product transfusion in patients with liver diseases.

Abstract
BackgroundPortal vein thrombosis (PVT) would exert a further increase in resistance to portal blood flow, resulting in worsening portal hypertension and poor outcome. This study aimed to identify risk factors and develop an clinically applicable dynamic nomogram predicting the occurrence of PVT in cirrhotic patients during primary prophylaxis for variveal hemorrhage (VH).MethodsThe multi-center retrospective study enrolled cirrhotic patients with high-risk varices, which were further divided into training and validation cohorts for 3 years follow-up. A dynamic nomogram based on the Cox proportional hazard regression model was developed with the cutoff value calculated by X-title analysis. The performance of the nomogram was evaluated with Harrell’s concordance index (C-index), calibration curve and decision curve analysis.Results91 (34.0%) of the whole cohort were diagnosed with PVT during 3-year follow-up. Variables including carvedilol (P < 0.001), low portal vein velocity (P < 0.001), increased size of esophageal varices (P = 0.005), and high HbA1c (P < 0.001) and procalcitonin (P = 0.015) were identified to be independently associated with PVT, which were further incorporated into the dynamic nomogram with optimal cutoff (8.8 and 14.6) for risk-stratification. The C-indexes (0.894 of internal validation and 0.892 of external validation) and calibration curves demonstrated ideal discrimination and calibration. The thresholds for more reasonable application of the nomogram were 0–0.27, 0–0.66, and 0.04–1.00 at 1, 2, and 3-year, respectively.ConclusionThe dynamic nomogram could be accurately and reliably used for clinical risk-stratification of PVT in cirrhotic patients during primary prophylaxis for VH.

Abstract
Portal vein thrombosis (PVT) is a common complication among patients with cirrhosis. However, its pathophysiology is not well established and there are currently very few predictive factors, none of which are actually useful, from a clinical perspective. The contribution of each of the vertices of Virchow’s triad, e.g., blood hypercoagulability, blood flow, and portal vein endothelial damage in the development of PVT is not clear. In this review, we aim to recapitulate the latest studies on the field of PVT development in order to understand its mechanisms and discuss some of the future directions in the study of this important complication of cirrhosis.

Abstract
Patients with cirrhosis of the liver are at high risk of developing portal vein thrombosis (PVT), which has a complex, multifactorial cause. The condition may present with a myriad of symptoms and can occasionally cause severe complications. Contrast-enhanced computed tomography (CT) is the gold standard for the diagnosis of PVT. There are uncertainties regarding the effect on PVT and its treatment outcome in patients with cirrhosis. The main challenge for managing PVT in cirrhosis is analyzing the risk of hemorrhage compared to the risk of thrombus extension leading to complications. All current knowledge regarding non-tumor PVT in cirrhosis, including epidemiology, risk factors, classification, clinical presentation, diagnosis, impact on natural history, and treatment, is discussed in the present article.

Front Pharmacol 2021; 12:785403. [PMID: 34899349 PMCID: PMC8656168 DOI: 10.3389/fphar.2021.785403] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 11/11/2021] [Indexed: 12/12/2022] Open
Abstract
Background and purpose: FXR is a promising target for the treatment of human cholestatic liver disease (CLD). SIRT1 is a deacetylase which promotes FXR activity through deacetylating FXR. Pterostilbene (PTE) is an activator of SIRT1. However, the role of PTE in cholestasis has so far not been investigated. We examined whether PTE treatment alleviate liver injury in DDC or ANIT-induced experimental cholestasis, and explored the underlying mechanisms. Experimental approach: Mice with DDC- or ANIT-induced cholestasis were treated with different dose of PTE. Primary hepatocytes and bone marrow derived macrophages were used in vitro to assess the molecular mechanism by which PTE may improve CLD. Identical doses of UDCA or PTE were administered to DDC- or ANIT-induced cholestasis mice. Key results: PTE intervention attenuated DDC or ANIT-induced cholestasis. PTE inhibited macrophage infiltration and activation in mouse liver through the SIRT1-p53 signaling pathway, and it improved hepatic bile metabolism through the SIRT1-FXR signaling pathway. Compare with UDCA, the same doses of PTE was more effective in improving cholestatic liver injury caused by DDC or ANIT. Conclusion and implications: SIRT1 activation in macrophages may be an effective CLD treatment avenue. Using CLD models, we thus identified PTE as a novel clinical candidate compound for the treatment of CLD.

Abstract
Portal vein thrombosis (PVT) is a severe disease that adversely affects patients' well-being. Data on the influence of PVT on the occurrence of depression or anxiety disorders are lacking. This study aimed to explore the impact of PVT on the incidence of depression and anxiety disorders diagnoses in a large German primary care cohort over a ten-year period. Patients with PVT were matched to non-PVT individuals by age, sex, yearly consultation frequency, index year and comorbidities in a 1:5 ratio. The primary outcome of the study was the incidence of depression and anxiety disorders. The relationship between PVT and both depression and anxiety disorders was investigated using Cox regression models. We compared 547 patients with PVT with 2735 matched individuals without PVT. Within 5 years of the index date, 17.4% of patients with PVT and 9.3% of non-PVT individuals were diagnosed with depression (p < 0.001). Anxiety disorders were diagnosed in 5.5% and 3.0% of patients with PVT and non-PVT individuals, respectively (p = 0.002). On regression analyses, PVT was positively associated with incident depression (HR 2.01, 95% CI 1.53-2.64, p < 0.001) as well as anxiety disorders (HR 2.16, 95% CI 1.35-3.46, p = 0.001). Regarding depression, this association remained significant in women as well as in men. There was no association between PVT and the incidence of anxiety disorders in women. In conclusion, PVT is associated with the development of depression and anxiety disorders. However, further prospective studies are needed to confirm our findings before definitive recommendations can be made.

Abstract
BACKGROUND Portal venous system thrombosis (PVST) will progress in some cases, indicating worse outcome and the necessity of antithrombotic treatment, but will spontaneously improve in others. It is crucial to understand the natural history of PVST in liver cirrhosis. However, the knowledge regarding how to predict the evolution of PVST in cirrhotic patients is very scant. METHODS Sixty-nine cirrhotic patients without malignancy, who had undergone repeated contrast-enhanced computed tomography or MRI to evaluate the severity of PVST at the first and last admissions, were included. Logistic regression analysis was performed to identify the risk factors for the evolution of PVST in liver cirrhosis. Odds ratios (ORs) were calculated. RESULTS Among 42 patients without PVST at the first admission, 10 (23.8%) developed PVST at the last admission. Serum albumin level (OR = 0.873), prothrombin time (OR = 1.619), activated partial thromboplastin time (OR = 1.169), Child-Pugh score (OR = 1.560) and model for end-stage liver disease (MELD) score (OR = 1.292) at the last admission were significant risk factors associated with the development of PVST. Among 27 patients with PVST at the first admission, 11 (40.7%), 4 (14.8%) and 12 (44.4%) had improvement, stabilization and progression of PVST at the last admission, respectively. ΔMELD score (OR = 0.714) was the only significant risk factor associated with the improvement of PVST; additionally, serum albumin level at the first admission (OR = 1.236) was the only significant risk factor associated with the progression of PVST. CONCLUSION Aggravation and amelioration of liver dysfunction may predict the development and improvement of PVST in liver cirrhosis, respectively.

Abstract
BACKGROUND & AIMS Portal vein thrombosis (PVT) is a relatively frequent event in patients with cirrhosis. While different risk factors for PVT have been reported, such as decreased portal blood flow velocity (PBFV) and parameters related with severity of portal hypertension, these are based on retrospective studies assessing only a discrete number of parameters. The aim of the current study was to evaluate the incidence and risks factors for non-tumoral PVT development in a large prospective cohort of patients with cirrhosis. METHODS We performed an exhaustive evaluation of clinical, biochemical, inflammatory and acquired/hereditary hemostatic profiles in 369 patients with cirrhosis without PVT who were prospectively followed-up. Doppler ultrasound was performed at baseline and every 6 months or whenever clinically indicated. PVT development was always confirmed by computed tomography. RESULTS Twenty-nine patients developed non-tumoral PVT, with an incidence of 1.6%, 6% and 8.4% at 1, 3 and 5 years, respectively. Low platelet count, PBFV <15 cm/sec and history of variceal bleeding were factors independently associated with a high PVT risk. No relationship between PVT development and any other clinical biochemical, inflammatory and acquired or hereditary hemostatic parameter was found. CONCLUSIONS In patients with cirrhosis, the factors predictive of PVT development were mainly those related to the severity of portal hypertension. Our results do not support the role of hemostatic alterations (inherited or acquired) and inflammatory markers in the prediction of PVT in patients with cirrhosis. LAY SUMMARY Patients with cirrhosis and more severe portal hypertension are at higher risk of non-tumoral portal vein thrombosis development. Acquired or inherited hemostatic disorders, as well as inflammatory status, do not seem to predict the development of portal vein thrombosis in patients with cirrhosis.

Abstract
BACKGROUND AND AIMS Various risk factors for portal vein thrombosis (PVT) development in patients with cirrhosis have been identified, but the role of systemic inflammatory reaction is unknown. The study aims to assess the association between markers of systemic inflammation and PVT in cirrhosis. METHODS Between January 2014 and October 2015, 107 outpatients with cirrhosis and no PVT were recruited, and followed till February 2017. White blood cell count, serum concentrations of high-sensitive C-reactive protein, ferritin, tumor necrosis factor-alpha and interleukin-6 (IL-6) were evaluated at baseline and every 3 or 6 months till PVT diagnosis or end of follow-up. RESULTS Median age, model for end-stage liver disease (MELD) score and follow-up period of the studied population was 55 years (IQR 46-62 years), 9.6 points (IQR 7.5-12 points) and 19 months (12-24 months), respectively. PVT developed in 10.3% of the patients. Lymphocyte count below 1.2 ´ 109/L [hazard ratio, 6.04; 95% confidence interval (CI), 1.29-28.2; P = 0.022], IL-6 above 5.5 pg/mL (hazard ratio, 5.64; 95% CI, 1.21-26.33; P = 0.028) and neutrophil-to-lymphocyte ratio (hazard ratio, 1.46; 95% CI, 1.04-2.04; P = 0.028) were associated with a higher risk of PVT development. IL-6 and lymphopenia remained associated with subsequent PVT development after adjustment for nonselective beta-blockers, spleen size, portosystemic collaterals, oesophageal varices (grade ≥2) and ascites, but also with alcohol as the cause for cirrhosis and MELD ≥13. CONCLUSION In patients with cirrhosis, markers of systemic inflammation IL-6 and lymphopenia are predictive of PVT independently of markers of portal hypertension. These results draw our attention on a factor so far overlooked in the pathogenesis of PVT.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) aggressiveness factors include serum levels of alpha-fetoprotein (AFP), maximum tumor diameter (MTD), tumor multifocality, and presence of portal vein thrombosis (PVT). AIMS The interdependence of these factors has not been closely studied. METHODS A large HCC database was examined for the presence of patients with PVT and multifocality and was analyzed retrospectively for the relationship of these 2 parameters to each other and to MTD and survival. RESULTS Multifocality was found to increase with increase in MTD in the whole cohort and especially in patients with PVT. PVT also increased with increasing MTD. Neither increases in multifocality nor in PVT depended on elevated serum AFP levels, although they each increased with higher AFP levels. PVT increased in monofocal tumors as MTD increased but increased further in multifocal tumors. CONCLUSIONS Multifocality and PVT appear to be separate processes, each increasing with increase in MTD and AFP levels. The data support the hypothesis that in hepatocarcinogenesis, various factors cause increase in MTD, that in turn causes increased multifocality and PVT, which are non-co-dependent. However, both multifocality and PVT mechanisms involve both HCC cell growth and invasiveness, multifocality in liver parenchyma, and PVT in the portal vein.

Abstract
Portal vein thrombosis (PVT) is one of the common complications of cirrhosis. Its formation is influenced by many factors, such as liver function grade, blood coagulation state, portal vein pressure, and blood flow velocity. The treatment of patients with PVT is more difficult than that of patients without PVT, and the prognosis is poor. However, the presence of PVT is usually asymptomatic, thus early detection and intervention are important. Currently, there are different views on the mechanism of PVT. This review will discuss the mechanism of PVT and summarize its pathogenesis, diagnosis, and treatment, with an aim to provide evidence for clinical practice.

Abstract
Hemostasis is a complex physiological process based on the balance between pro-coagulant and anticoagulant systems to avoid pathological bleeding or thrombosis. The changes in standard coagulation tests in liver disease were assumed to reflect an acquired bleeding disorder, and cirrhotic patients were considered naturally anticoagulated. In the light of the new evidence, the theory of rebalanced hemostasis replaced the old concept. According to this model, the hemostatic alteration leads to a unique balance between pro-coagulant, anticoagulant, and fibrinolytic systems. But the balance is fragile and may prone to bleeding or thrombosis depending on various risk factors. The standard coagulation tests [INR (international normalized ratio), platelet count and fibrinogen] only explore parts of the hemostasis, not offering an entire image of the process. Rotational thromboelastometry (ROTEM) and thromboelastography (TEG) are both point of care viscoelastic tests (VET) that provide real-time and dynamic information about the entire hemostasis process, including clot initiation (thrombin generation), clot kinetics, clot strength, and clot stability (lysis). Despite prolonged PT/INR (international normalized ratio of prothrombin time) and low platelet counts, VET is within the normal range in many patients with both acute and chronic liver disease. However, bleeding remains the dominant clinical issue in patients with liver diseases, especially when invasive interventions are required. VET has been shown to asses more appropriately the risk of bleeding than conventional laboratory tests, leading to decrial use of blood products transfusion. Inappropriate clotting is common but often subtle and may be challenging to predict even with the help of VET. Although VET has shown its benefit, more studies are needed to establish cut-off values for TEG and ROTEM in these populations and standardization of transfusion guidelines before invasive interventions in cirrhotic patients/orthotopic liver transplantation.

Abstract
BACKGROUND AND AIM Hemostasis profile is often complicated in liver cirrhosis. Thromboelastography is a global viscoelastic test recommended by the current practice guideline and consensus. This cross-sectional study aimed to evaluate the association of thromboelastography profile with severity of liver cirrhosis and presence of portal venous system thrombosis (PVST). METHODS Overall, 116 and 50 cirrhotic patients were included in the Shenyang and Xi'an cohorts, respectively. Thromboelastography parameters were compared between cirrhotic patients with Child-Pugh class A and B/C, those with and without decompensated events, and those with and without PVST. Hypercoagulability would be considered if at least two of the following thromboelastography parameters were met: shortened reactive time (R), shortened coagulation time (K), increased angle, and increased maximum amplitude (MA). RESULTS In the Shenyang cohort, 16 patients had shortened R, of whom seven (43.75%) had prolonged K and 11 (68.75%) decreased MA. In the Xi'an cohort, 24 patients had shortened R, of whom seven (29.17%) had prolonged K and 15 (62.50%) decreased MA. In the Shenyang cohort, the prevalence of hypercoagulability was not significantly different between cirrhotic patients with Child-Pugh class A and B/C (3.85% vs. 6.25%, P = 0.873), those with and without decompensated events (5.49% vs. 4.00%, P = 1.000), and those with and without PVST (4.17% vs. 5.88%, P = 1.000), which were similar to the results obtained in the Xi'an cohort. CONCLUSION There is a high rate of discordance between R and other thromboelastography parameters. In addition, hypercoagulability may not be related to more advanced stage of liver cirrhosis or presence of PVST.

Abstract
BACKGROUND AND AIM Hemostasis profile is often complicated in liver cirrhosis. Thromboelastography is a global viscoelastic test recommended by the current practice guideline and consensus. This cross-sectional study aimed to evaluate the association of thromboelastography profile with severity of liver cirrhosis and presence of portal venous system thrombosis (PVST). METHODS Overall, 116 and 50 cirrhotic patients were included in the Shenyang and Xi'an cohorts, respectively. Thromboelastography parameters were compared between cirrhotic patients with Child-Pugh class A and B/C, those with and without decompensated events, and those with and without PVST. Hypercoagulability would be considered if at least two of the following thromboelastography parameters were met: shortened reactive time (R), shortened coagulation time (K), increased angle, and increased maximum amplitude (MA). RESULTS In the Shenyang cohort, 16 patients had shortened R, of whom seven (43.75%) had prolonged K and 11 (68.75%) decreased MA. In the Xi'an cohort, 24 patients had shortened R, of whom seven (29.17%) had prolonged K and 15 (62.50%) decreased MA. In the Shenyang cohort, the prevalence of hypercoagulability was not significantly different between cirrhotic patients with Child-Pugh class A and B/C (3.85% vs. 6.25%, P = 0.873), those with and without decompensated events (5.49% vs. 4.00%, P = 1.000), and those with and without PVST (4.17% vs. 5.88%, P = 1.000), which were similar to the results obtained in the Xi'an cohort. CONCLUSION There is a high rate of discordance between R and other thromboelastography parameters. In addition, hypercoagulability may not be related to more advanced stage of liver cirrhosis or presence of PVST.

Abstract
Portal vein thrombosis (PVT) is a common and severe complication of liver cirrhosis. So far, there have been few consensuses or practice guidelines on the management of PVT in liver cirrhosis. In this expert consensus, we systematically review the epidemiology, risk factors, imaging examinations, diagnosis, assessment of disease severity, and treatment strategy of PVT in liver cirrhosis, based on the most recent evidence and expert opinions, to further standardize the diagnosis and treatment of the disease in clinical practice.

Abstract
Portal vein thrombosis (PVT) is one of the common complications of liver cirrhosis, which can further increase portal vein pressure and aggravate liver function decompensation. However, due to the insidious onset and atypical symptoms, the importance of PVT has been neglected in clinical work for quite a long time. With the development of clinical diagnostic technology, the detection rate of PVT has increased year by year. At present, the well-established treatment methods for PVT include anticoagulant therapy, interventional therapy, and surgical treatment. However, the optimal choice for PVT treatment remains unclear. In this paper, we briefly review the recent progress in the diagnosis and treatment of PVT in order to provide a theoretical reference for the refined clinical management of patients with PVT.

Abstract
Nontumoral portal vein thrombosis (PVT) is an increasingly recognized complication in patients with cirrhosis. Substantial evidence shows that portal flow stasis, complex thrombophilic disorders, and exogenous factors leading to endothelial dysfunction have emerged as key factors in the pathogenesis of PVT. The contribution of PVT to hepatic decompensation and mortality in cirrhosis is debatable; however, the presence of an advanced PVT increases operative complexity and decreases survival after transplantation. The therapeutic decision for PVT is often determined by the duration and extent of thrombosis, the presence of symptoms, and liver transplant eligibility. Evidence from several cohorts has demonstrated that anticoagulation treatment with vitamin K antagonist or low molecular weight heparin can achieve recanalization of the portal vein, which is associated with a reduction in portal hypertension-related events and improved survival in cirrhotic patients with PVT. Consequently, interest in direct oral anticoagulants for PVT is increasing, but clinical data in cirrhosis are limited. Although the most feared consequence of anticoagulation is bleeding, most studies indicate that anticoagulation therapy for PVT in cirrhosis appears relatively safe. Interestingly, the data showed that transjugular intrahepatic portosystemic shunt represents an effective adjunctive therapy for PVT in cirrhotic patients with symptomatic portal hypertension if anticoagulation is ineffective. Insufficient evidence regarding the optimal timing, modality, and duration of therapy makes nontumoral PVT a challenging consequence of cirrhosis. In this review, we summarize the current literature and provide a potential algorithm for the management of PVT in patients with cirrhosis.

A Preclinical Porcine Model of Portal Vein Thrombosis in Liver Cirrhosis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:3086906. [PMID: 32351989 PMCID: PMC7171646 DOI: 10.1155/2020/3086906] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Revised: 01/19/2020] [Accepted: 01/29/2020] [Indexed: 11/17/2022]
Abstract
Background This study aimed at presenting a novel method of developing a porcine model of portal vein thrombosis (PVT) in cirrhosis by intravenous administration of thrombin and insertion of a fibered coil. We further investigated changes of biochemical parameters, coagulation, and proinflammatory cytokine expression in the cirrhosis-PVT group. Methods Twelve male pigs were randomized into the control group (n = 3) and cirrhosis group (n = 9). In cirrhotic pigs, three were randomly selected to establish PVT by ultrasound-guided percutaneous puncture of the main portal vein (MPV) followed by intravenous thrombin administration and fibered coil insertion. Thrombosis in the MPV was detected by abdominal enhanced computer tomography (CT). The changes of hepatic function, coagulation system, and inflammation cytokines were compared among normal, cirrhosis, and cirrhosis with PVT groups. Results As manifested by the presence of a filling defect in MPV on portal venous-phase CT angiography, fibrin thrombi were formed in the MPV in cirrhotic pigs within one week and persisted for four weeks. Five weeks after surgery, abnormal liver functions occurred in association with PVT formation in cirrhosis. Both coagulation and thromboelastography parameters showed that cirrhosis-PVT pigs exhibited a procoagulant state through hyperfunction of platelets and clotting factors. Interleukin 6 (IL-6) as a potential inflammatory marker stimulated PVT-mediated inflammation activation in cirrhosis. Conclusions Our study provides in vivo evidence that intravenous injection of a coil and thrombin into MPV under interventional guided devices enables a feasible method in thrombus creation. Further exploration and validation of large-sample cases are required to characterize utilities of this model.

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.
