Altered clot formation and lysis are associated with increased fibrinolytic activity in ascites in patients with advanced cirrhosis.

Analysis of coagulation disorders and assessment of rebalanced hemostasis with the use of traditional coagulation assays is challenging in cirrhotic patients. Therefore, alternative tests are under investigation for the evaluation of coagulopathy in this specific setting. Aim of this study was to analyze the modifications of clot structure and function in cirrhotic patients with different degrees of severity. Cirrhotic patients referred to our Unit were consecutively enrolled. Global test measurements, including clot and lysis assays, clot lysis time, and determination of other fibrinolytic parameters, were performed. Analyses of clot formation, morphology, and lysis were performed with a turbidimetric clotting and lysis assay (EuroCLOT). Lysis of a tissue factor-induced clot by exogenous tissue plasminogen activator was analyzed by studying the modifications of turbidity during clot formation and the following lysis. We evaluated coagulative and fibrinolytic parameters in both plasma and ascites. Urokinase plasminogen activator (uPA) and gelatinase activity in ascites were also measured. We analyzed data from 33 cirrhotic patients (11 in Child-Pugh class A; 22 in class B or C and with ascites) and 21 healthy subjects (HS). In class B/C patients prolonged latency time, a decline in clotting absorbance, and decreased fibrin formation were observed in comparison with class A and HS. Generated curves and Thrombin-Activatable Fibrinolysis Inhibitor (TAFI) progressively declined from HS to class C patients, whereas levels of plasminogen activator inhibitor-1 and tissue plasminogen activator increased. D-dimer levels were markedly increased in ascites, together with significantly smaller levels of TAFI, αlfa2-antiplasmin, and plasminogen. Caseinolytic activity was also present. Class C patients showed smaller amount of uPA and significantly lower levels of matrix metallopeptidases (MMP)2 in ascites in comparison with Class B subjects. Clot formation and lysis are altered in cirrhosis and fibrinolysis is activated in ascites. Ascitic levels of uPA and MMP2 are reduced and inversely related to the severity of liver disease.

Characterization of lymphocyte subsets in ascitic fluid and peripheral blood of decompensated cirrhotic patients with chronic hepatitis C and alcoholic liver disease: A pivotal study.

Hepatitis C virus and alcoholic liver disease are major causes of chronic liver diseases worldwide. Little is known about differences between chronic hepatitis C and alcoholic liver disease in terms of lymphocytes' sub-population. Aim of the present study was to compare the sub-populations of lymphocytes in both ascitic compartment and peripheral blood in patients with decompensated liver cirrhosis due to chronic hepatitis C and alcoholic liver disease. Patients with decompensated liver cirrhosis due to hepatitis C virus or alcoholic liver disease evaluated from April 2014 to October 2016 were enrolled. Whole blood and ascitic fluid samples were stained with monoclonal antibodies specific for human TCRɑß, TCRɣδ, CD3, CD4, CD8, CD19, CCR6, CD16, CD56, CD25, HLA-DR, Vɑ24. Sixteen patients with decompensated liver cirrhosis were recruited (9 with hepatitis C virus and 7 with alcoholic liver disease). In ascitic fluid, the percentage of both CD3+CD56- and CD3+CD56+iNKT cells resulted higher in hepatitis C virus patients than in alcoholic liver disease patients (1.82 ± 0.35% vs 0.70 ± 0.42% (p < 0.001) and 1.42 ± 0.35% vs 0.50 ± 0.30% (p < 0.001), respectively). Conversely, in peripheral blood samples, both CD3+CD56- and CD3+CD56+iNKT cells resulted significantly higher in alcoholic liver disease than in hepatitis C virus patients (4.70 ± 2.69% vs 1.50 ± 1.21% (p < 0.01) and 3.10 ± 1.76% vs 1.00 ± 0.70% (p < 0.01), respectively). Both elevation of iNKT cells in ascitic fluid and reduction in peripheral blood registered in hepatitis C virus but not in alcoholic liver disease patients might be considered indirect signals of tissutal translocation. In conclusion, we described relevant differences between the two groups. Alcoholic liver disease patients displayed lower number of CD3+CD4+ cells and a higher percentage of CD3-CD16+, Vα24+CD3+CD56- and Vα24+CD3+CD56+iNKT cells in ascitic fluid than hepatitis C virus positive subjects. Further studies might analyze the role of immune cells in the vulnerability toward infections and detect potential targets for new treatments especially for alcoholic liver disease patients.

Long-term albumin administration in decompensated cirrhosis (ANSWER): an open-label randomised trial.

BACKGROUND: Evidence is scarce on the efficacy of long-term human albumin (HA) administration in patients with decompensated cirrhosis. The human Albumin for the treatmeNt of aScites in patients With hEpatic ciRrhosis (ANSWER) study was designed to clarify this issue. METHODS: We did an investigator-initiated multicentre randomised, parallel, open-label, pragmatic trial in 33 academic and non-academic Italian hospitals. We randomly assigned patients with cirrhosis and uncomplicated ascites who were treated with anti-aldosteronic drugs (≥200 mg/day) and furosemide (≥25 mg/day) to receive either standard medical treatment (SMT) or SMT plus HA (40 g twice weekly for 2 weeks, and then 40 g weekly) for up to 18 months. The primary endpoint was 18-month mortality, evaluated as difference of events and analysis of survival time in patients included in the modified intention-to-treat and per-protocol populations. This study is registered with EudraCT, number 2008-000625-19, and ClinicalTrials.gov, number NCT01288794. FINDINGS: From April 2, 2011, to May 27, 2015, 440 patients were randomly assigned and 431 were included in the modified intention-to-treat analysis. 38 of 218 patients died in the SMT plus HA group and 46 of 213 in the SMT group. Overall 18-month survival was significantly higher in the SMT plus HA than in the SMT group (Kaplan-Meier estimates 77% vs 66%; p=0·028), resulting in a 38% reduction in the mortality hazard ratio (0·62 [95% CI 0·40-0·95]). 46 (22%) patients in the SMT group and 49 (22%) in the SMT plus HA group had grade 3-4 non-liver related adverse events. INTERPRETATION: In this trial, long-term HA administration prolongs overall survival and might act as a disease modifying treatment in patients with decompensated cirrhosis.

Recent Advancements in Diagnosis and Therapy of Liver Cirrhosis.

Cirrhosis is a diffuse pathophysiological state of the liver considered to be the final stage of various liver injuries, characterized by chronic necroinflammatory and fibrogenetic processes, with subsequent conversion of normal liver architecture into structurally abnormal nodules, dense fibrotic septa, concomitant parenchymal exaustment and collapse of the liver tissue. Alcoholic liver disease and chronic infections due to HBV and/or HCV constitute the main causes of liver cirrhosis worldwide. During a lag time of 15 to 30 years, chronic liver diseases can lead to liver cirrhosis and its complications. Active hepatic inflammation plays a pivotal role in the inflammation- necrosis-regeneration process, which eventually leads to liver cirrhosis and hepatocellular carcinoma. Prognosis of liver cirrhosis is highly variable and influenced by several variables, such as etiology, severity of liver disease, presence of complications and comorbidities. In advanced cirrhosis, survival decreases to one or two years. Correct advanced diagnosis and selected treatment with different molecules may help in understanding mechanisms of fibrogenesis, the driving forces of cirrhosis's pathogenesis, and the scrupulous approach to more effective therapeutic procedures. Prevention of fibrosis with further deterioration of liver function through specific treatments is always required, through the removal of the underlying causes of liver disease. Advanced liver disease, with subsequent complications, requires targeted treatment. Therefore, the aim of this review is to assess the diagnosis and treatment of liver cirrhosis on the pathophysiological bases, searching for relevant studies published in English using the PubMed database from 2011 to the present.

Screening of distress among hospitalized patients in a department of internal medicine.

A psychosomatic approach to the basic screening of distress for patient care in hospitals and other health services is presented. The aims of this study were to verify association between: (1) medical illnesses and distress; (2) patients' needs and distress; (3) type of illness and patients' needs; (4) patients' needs and sense of coherence. One hundred and eighty-nine patients (78 F and 111 M, average age 65 years±8.43) were assessed by self-report questionnaires. We found that higher anxiety and/or depression levels were associated with urogenital (p=0.026), rheumatologic (p=0.006), oncological (p=0.011), neurological (p=0.026) and respiratory (p=0.013) illnesses. Higher distress scoring was associated with rheumatologic illnesses (p=0.024) and illnesses of the liver and digestive system (p=0.037) while a higher severity of distress was associated with oncological illnesses (p=0.011). Depression/anxiety were associated with the need to speak to a psychologist (p=0.050), to a spiritual advisor (p=0.009), to be more reassured by relatives (p=0.017), to feel less abandoned (p=0.036). Only low sense of coherence was associated with the need for greater dialogue with physicians (p=0.012), the need to participate less in treatment decisions (p=0.041), the need to feel less left to one's own devices (p=0.023). Several needs are associated with medical illnesses. In conclusion, these results indicate that early psychological screening could be important to avoid worse or chronic distress.

Terlipressin plus albumin versus midodrine and octreotide plus albumin in the treatment of hepatorenal syndrome: A randomized trial.

UNLABELLED: Hepatorenal syndrome (HRS), a serious complication of cirrhosis, is associated with high mortality without treatment. Terlipressin with albumin is effective in the reversal of HRS. Where terlipressin is not available, as in the United States, midodrine and octreotide with albumin are used as an alternative treatment of HRS. The aim was to compare the effectiveness of terlipressin plus albumin versus midodrine and octreotide plus albumin in the treatment of HRS in a randomized controlled trial. Twenty-seven patients were randomized to receive terlipressin with albumin (TERLI group) and 22 to receive midodrine and octreotide plus albumin (MID/OCT group). The TERLI group received terlipressin by intravenous infusion, initially 3 mg/24 hours, progressively increased to 12 mg/24 hours if there was no response. The MID/OCT group received midodrine orally at an initial dose of 7.5 mg thrice daily, with the dose increased to a maximum of 12.5 mg thrice daily, together with octreotide subcutaneously: initial dose 100 µg thrice daily and up to 200 µg thrice daily. Both groups received albumin intravenously 1 g/kg of body weight on day 1 and 20-40 g/day thereafter. There was a significantly higher rate of recovery of renal function in the TERLI group (19/27, 70.4%) compared to the MID/OCT group (6/21, 28.6%), P = 0.01. Improvement in renal function and lower baseline Model for End-Stage Liver Disease score were associated with better survival. CONCLUSION: Terlipressin plus albumin is significantly more effective than midodrine and octreotide plus albumin in improving renal function in patients with HRS.

Paradoxical embolization in TIPS: take a closer look to the heart.

No definitive indications are provided in the literature for pre-TIPS patient workup, which is often limited to prevent the incidence of refractory hepatic encephalopathy or unacceptable deterioration of liver function. Concerning cardiologic workup, efforts are generally limited at excluding ventricular failure or porto pulmonary hypertension. The cases presented herein focus the attention of the readers on the possible occurrence of post-TIPS paradoxical embolization in the presence of a patent foramen ovale, frequently recognized in adult population. In conclusion, although this complication has been already reported in literature, in the present manuscript we concentrate on possible additional risk factors which may allow to identify a subset of patients with a higher likelihood to experience paradoxical embolization following TIPS. Another important line of information presented herein is the feasibility of percutaneous closure of a patent foramen ovale before TIPS deployment in the presence of portal vein thrombosis and possibly with additional risk factors.

Low-dose topiramate in alcohol dependence: a single-blind, placebo-controlled study.

INTRODUCTION: Topiramate (TOP) and anticonvulsants in general are considered safe and effective drugs for the treatment of alcohol dependence, even though TOP-induced adverse events are quite common, especially for high initial doses or if titration to 300 mg/d is too rapid. The aim of the present study was to assess the efficacy and tolerability profile of low-dose TOP for relapse prevention. METHODS: After detoxification, 52 patients were randomized into 2 groups as follows: 26 patients received 100 mg of TOP (oral, twice daily), titrated over 2 weeks, and 26 patients received placebo (PLA). Both groups underwent rehabilitation twice a week. RESULTS: After 6 weeks of treatment, compared with the PLA group, patients receiving TOP showed the following: (1) fewer drinking days (P < 0.05); (2) less daily alcohol consumption (P < 0.05); (3) more days of treatment (P < 0.05); (4) reduced levels of craving (Obsessive-Compulsive Drinking Scale) and withdrawal symptoms (Clinical Institute Withdrawal Assessment for Alcohol-Revised); and (5) improvement of anxiety, depression, and obsessive-compulsive symptom severity (Symptom Check List 90 Revised). CONCLUSIONS: Despite the small sample size and the short follow-up period, the present PLA-controlled study demonstrated the potential usefulness of TOP, even when administered at a dosage of 100 mg/d, for the treatment of detoxified alcohol-dependent subjects, confirming results from previous studies testing higher doses of TOP.

Fish oil supplementation reduces cortisol basal levels and perceived stress: a randomized, placebo-controlled trial in abstinent alcoholics.

Behavioral distress and dysfunctions of hypothalamic-pituitary-adrenocortical (HPA) axis play a central role in alcohol abuse. Omega-3 fatty acids are proposed as having antistress, regulatory effects on HPA responsiveness, but a possible protective role in ethanol addiction is unexplored.A randomized, doubleblind, placebo-controlled trial was performed in male alcoholics undergoing residential rehabilitation program, to evaluate the effects of 3-week supplementation with fish-oil providing eicosapentaenoic (60 mg/day) and docosahexaenoic acid (252 mg/day) on perceived stress/anxiety and HPA activity, assessed by measuring saliva basal cortisol levels at various daytimes (0730 h, 1130 h, 1600 h, 2000 h, and 2400 h) and the acute cortisol response to Trier Social Stress Test.Results showed that in supplemented subjects, before versus after decrease of stress/anxiety ratings was accompanied by reduction of cortisol basal levels throughout the day; no changes were observed in placebo group. At the end of intervention, amplitude, and duration of stress-evoked cortisol response did not differ between groups; however, the peak of cortisol response was temporally anticipated in supplemented subjects. In conclusion, an elevated omega-3 intake may reduce distress symptoms and basal cortisol secretion in abstinent alcoholics, thus providing a valid subsidiary measure to increase the efficacy of rehabilitation programs in ethanol addicts.

Hepato-systemic gradient of carbon monoxide in cirrhosis.

BACKGROUND AND AIMS: Experimental data suggest that in liver cirrhosis splanchnic and systemic vasculature exhibit marked endothelial Carbon monoxide (CO) overproduction, while recent data demonstrated heme oxygenase (HO) hyperactivity in the liver of rats with cirrhosis. No data are so far available on CO levels in the hepatic veins of cirrhotic patients. We aimed at evaluating whether plasma CO levels differ between systemic (peripheral vein) and hepatic (hepatic vein) circulation in patients with viral cirrhosis with and without ascites. METHODS: We enrolled 31 consecutive non-smoking in- or outpatients with liver cirrhosis. We measured wedge (occluded, WHVP) and free hepatic venous pressures (FHVP) and hepatic-vein pressure gradient (HVPG) was the calculated. Plasma level of NO and plasma CO concentration were determined both in peripheral vein and in the hepatic vein in cirrhotics. RESULTS: In cirrhotic patients plasma CO levels were significantly higher in the hepatic vein (16.66±10.71 p.p.m.) than in the peripheral vein (11.71±7.00 p.p.m). Plasma NO levels were significantly higher in peripheral vein (97.02±21.11 µmol/ml) than in the hepatic vein (60.76±22.93 µmol/ml). CONCLUSIONS: In patients with liver cirrhosis we documented a hepato-systemic CO gradient as inferred by the higher CO values in the hepatic vein than in the peripheral vein. In cirrhotic patients, CO and NO exhibit opposite behavior in the liver, while both molecules show increased values in the systemic circulation. It can be speculated that increased intra-hepatic CO levels might represent a counterbalancing response to reduced NO intra-hepatic levels in human liver cirrhosis.

Elevated plasma levels of urotensin II do not correlate with systemic haemodynamics in patients with cirrhosis.

BACKGROUND: The hyperdynamic circulation of hepatic cirrhosis is related to decreased systemic vascular resistance due to arterial vasodilation. Urotensin II plasma levels are increased in cirrhotic patients, and have been suggested to play a role in the pathogenesis of systemic haemodynamic alterations. AIM: To evaluate the relationships between systemic haemodynamics and urotensin II plasma levels. METHODS: Thirty-six consecutive in-patients with cirrhosis and no alteration of plasma creatinine, and 20 age- and gender-matched healthy volunteers underwent noninvasive assessment of systemic haemodynamics and measurement of urotensin II plasma levels. RESULTS: In comparison to healthy controls, cirrhotic patients had signs of hyperdynamic circulation and higher plasma urotensin II levels. Plasma urotensin II was neither significantly different amongst patients with different severity of cirrhosis nor between patients with or without ascites. Both in controls and cirrhotic patients no significant correlations were found between parameters of systemic haemodynamics and plasma urotensin II levels. CONCLUSIONS: In patients with cirrhosis and hyperdynamic circulation, but with normal serum creatinine, urotensin II is higher than in healthy subjects. However, no correlation with cardiac index or other haemodynamic parameters was observed, indicating that other mechanisms prevail.

Pregabalin, tiapride and lorazepam in alcohol withdrawal syndrome: a multi-centre, randomized, single-blind comparison trial.

INTRODUCTION: The aim of this trial was to compare lorazepam with non-benzodiazepine medications such as pregabalin and tiapride in the treatment of alcohol withdrawal syndrome (AWS). These drugs were chosen for their inhibitorial effects on the hypersecretion of neurotransmitters usually observed in AWS. Craving reduction and improvement of psychiatric symptoms were the secondary end-points. METHODS: One hundred and ninety subjects affected by current alcohol dependence were considered consecutively: 111 were enrolled and divided into three groups of 37 subjects each. Within a treatment duration of 14 days, medication was given up to the following maximum doses (pregabalin 450 mg/day; tiapride 800 mg/day; lorazepam 10 mg/day). Withdrawal (CIWA-Ar), craving [visual analogue scale (VAS); Obsessive and Compulsive Drinking Scale (OCDS)], psychiatric symptoms [Symptom Check List 90 Revised (SCL-90-R)] and quality of life (QL-index) rating scales were applied. RESULTS: On the CIWA-Ar score, all the groups showed a significant reduction between times (P < 0.001) with a higher reduction for the pregabalin group (P < 0.01) on items regarding headache and orientation. Retention in treatment was lower in the tiapride group (P < 0.05), while the number of subjects remaining alcohol free was higher in the pregabalin group (P < 0.05). Significant reduction between baseline and the end of the treatment was found in all the groups at the OCDS and the VAS for craving, at the SCL-90-R and QL-index (P < 0.001). DISCUSSION: All the medications in the trial showed evidence of safety and efficacy in the treatment of uncomplicated forms of AWS, with some particular differences. The efficacy of pregabalin was superior to that of tiapride, used largely in research trials and, for some measures, to that of the 'gold standard', lorazepam. Accordingly, pregabalin may be considered as a potentially useful new drug for treatment of AWS, deserving further investigation.

Increased plasma carbon monoxide in patients with viral cirrhosis and hyperdynamic circulation.

OBJECTIVES: Our aim was to measure plasma carbon monoxide (CO) in patients with liver cirrhosis and portal hypertension. METHODS: In 36 cirrhotic patients (24 with ascites) and 9 healthy volunteers, we evaluated CO plasma levels and systemic hemodynamics (using ultra-trace gas chromatography and echocardiography, respectively). Heme oxygenase (HO) activity and expression were measured in isolated polymorphonuclear (PMN) cells. RESULTS: Plasma CO level (mean+/-s.d.) was 5.81+/-1.31 p.p.m. in healthy subjects (HS), significantly higher in non-ascitic patients (16.24+/-4.61 p.p.m., P<0.01), and even more high in ascitic patients (28.50+/-7.27 p.p.m., P<0.01 vs. the other two groups). HO activity in PMN cells was significantly greater in patients than in HS, with the highest levels being observed in patients with ascites. Western blot analysis showed enhanced expression of HO-1, but not HO-2. In the whole series of cirrhotic patients, plasma CO levels directly correlated with cardiac output, and inversely with systemic vascular resistance and mean arterial pressure. CONCLUSIONS: The HO/CO system is activated in patients with liver cirrhosis. This could contribute to the hyperdynamic circulatory syndrome observed in this condition.

Activation of p38(MAPK) mediates the angiostatic effect of the chemokine receptor CXCR3-B.

Chemokines binding the CXCR3 receptor have been shown to inhibit angiogenesis via the CXCR3-B isoform, but the underlying molecular mechanisms are unknown. Aim of this study was to elucidate the effects of CXCR3-B on activation of members of the mitogen-activated protein kinase family, and to explore the relevance of defined signaling pathways to the angiostatic effects of CXCR3-B ligands. Human embryonic kidney (HEK) 293 cells were transfected with expression vectors encoding for CXCR3-A or CXCR3-B. In cells expressing CXCR3-A, CXCL10 (IP-10) at nanomolar concentrations induced activation of ERK, Akt, and Src, as previously described in human vascular pericytes. In HEK-293 cells expressing CXCR3-B, exposure to CXCL10 in the micromolar concentration range led to activation of the p38(MAPK) pathway, as indicated by phosphorylation of p38(MAPK) itself, and of MKK3/6 and MAPKAPK-2, that lie upstream and downstream of p38(MAPK), respectively. Similar results were obtained in cells stimulated with CXCL4 (PF4), a specific ligand of CXCR3-B. In contrast, CXCL4 was unable to activate p38(MAPK) in mock-transfected HEK-293 cells. Only a modest induction of ERK or JNK was observed upon CXCR3-B activation. In human microvascular endothelial cells, which selectively express CXCR3-B, in a cell cycle-dependent fashion, CXCL10 and CXCL4 increased the enzymatic activity of p38(MAPK). Pharmacologic inhibition of p38(MAPK) by SB302580 resulted in a significant increase in DNA synthesis and in reversal of the inhibitory action of CXCL10. In conclusion, the p38(MAPK) pathway is a downstream effector of CXCR3-B implicated in the angiostatic action of this chemokine receptor.

Performance of Doppler ultrasound in the prediction of severe portal hypertension in hepatitis C virus-related chronic liver disease.

PURPOSE: To evaluate the correlation between hepatic vein pressure gradient measurement and Doppler ultrasonography (DUS) in patients with chronic liver disease (CLD). PATIENTS AND METHODS: Sixty-six patients with fibrotic to cirrhotic hepatitis C virus-related CLD, were consecutively included upon referral to our haemodynamic laboratory. Superior mesenteric artery pulsatility index (SMA-PI), right interlobar renal and intraparenchymal splenic artery resistance indices, were determined, followed by hepatic venous pressure gradient (HVPG) measurement. RESULTS: A correlation was found between HVPG and intraparenchymal splenic artery resistance index (SA-RI) (r=0.50, P<0.0001), SMA-PI (r=-0,48, P<0.0001), right interlobar renal artery resistance index (RRA-RI) (r=0.51, P<0.0001) in the whole patient population. However, dividing patients according to the presence/absence of severe portal hypertension (i.e. HVPG > or =12 mmHg), a correlation between HVPG and intraparenchymal SA-RI (r=0.70, P<0.0001), SMA-PI (r=-0.49, P=0.02), RRA-RI (r=0.66, P=0.0002) was observed only for HVPG values <12 mmHg. HVPG but not DUS correlated with the presence of esophageal varices (P<0.0001). CONCLUSIONS: Superior mesenteric artery pulsatility index, intraparenchymal splenic and right interlobar renal artery resistance indices do not adequately predict severe portal hypertension.

Liver stiffness measurement predicts severe portal hypertension in patients with HCV-related cirrhosis.

UNLABELLED: Measurement of hepatic venous pressure gradient (HVPG) is a standard method for the assessment of portal pressure and correlates with the occurrence of its complications. Liver stiffness measurement (LSM) has been proposed as a noninvasive technique for the prediction of the complications of cirrhosis. In this study, we evaluated the ability of LSM to predict severe portal hypertension compared with that of HVPG in 61 consecutive patients with HCV-related chronic liver disease. A strong relationship between LSM and HVPG measurements was found in the overall population (r=0.81, P<0.0001). However, although the correlation was excellent for HVPG values less than 10 or 12 mm Hg (r=0.81, P=0.0003 and r=0.91, P<0.0001, respectively), linear regression analysis was not optimal for HVPG values>or=10 mm Hg (r2=0.35, P<0.0001) or>or=12 mm Hg (r2=0.17, P=0.02). The AUROC for the prediction of HVPG>or=10 and >or=12 mm Hg were 0.99 and 0.92, respectively and at LSM cutoff values of 13.6 kPa and 17.6 kPa, sensitivity was 97% and 94%, respectively. In patients with cirrhosis, LSM positively correlated with the presence of esophageal varices (P=0.002), although no correlation between LSM and esophageal varices size was detected. The area under the ROC for the prediction of EV was 0.76 and at a LSM cutoff value of 17.6 kPa sensitivity was 90%. CONCLUSION: LSM represents a non-invasive tool for the identification of chronic liver disease patients with clinically significant or severe portal hypertension and could be employed for screening patients to be subjected to standard investigations including upper GI endoscopy and hemodynamic studies.
