Abstract
BACKGROUND Reversibility of advanced fibrosis after HCV-clearance is an important goal of therapy. OBJECTIVES Measuring liver stiffness (LS) by transient elastography (TE) might be helpful in this setting. PATIENTS AND METHODS We evaluated 104 patients with biopsy-proven chronic hepatitis C (CHC) and sustained virological response (SVR) after Peg-Interferon (IFN) plus ribavirin since at least 18 months. HCV-eradication was confirmed searching for serum HCV-RNA (TMA® sensitivity > 5-10 IU/ml). Data from literature reported the best LS cut-off values for different stages of liver fibrosis were 7.1 kPa for Metavir stage 2 (F2), 9.5 kPa for F3 and 12.5 for cirrhosis (F4). RESULTS TE was not reliable in four SVR obese patients. Metavir-stage of biopsy was F0-1 in 28, F2 in 47, F3 in 17 and F4 in eight patients. The median interval elapsed since achieving SVR was 36 months (range: 18-77, SD¬¬:18). Stratifying patients according to the histological stage assessed before treatment, a clear-cut gradient of LS values was observed from F0-1: median: 3.8 kPa (range: 3.5-4.9) to F2: 4.6 kPa (3.8-6.0), F3: 6.2 kPa (4.8-8.6) and F4: 8.4 kPa (6.2-9.2) (P = 0.001). Overall, 86 patients had lower values of LS than the expected LS values according to Metavir-stage. At multivariate logistic analysis γ-GT and histological steatosis were independently associated with persistence of higher values of LS. CONCLUSION Long term responders to IFN-based therapies have lower LS values than those who are untreated and still viraemic. High levels of γ-GT and liver steatosis, all markers of insulin resistance, may hamper reduction of liver stiffness after HCV-clearance.

Abstract
Background: Assessment of liver fibrosis and steatosis is now almost indispensable in most of the chronic liver diseases in order to determine prognosis and need for treatment, and to monitor disease progression and response to treatment. Liver biopsy is limited by its invasiveness and patient acceptability. Transient elastography (TE; Fibroscan) is a non-invasive tool with satisfactory accuracy and reproducibility to estimate liver fibrosis. Aims & Methods: To review the existing evidence concerning the clinical applications of TE in major liver diseases, including chronic hepatitis B and -C, non-alcoholic fatty liver disease (NAFLD), alcoholic liver disease, primary biliary cirrhosis and primary sclerosing cholangitis. Results: As alanine aminotransferase (ALT) is one of the major confounding factors of liver stiffness in chronic hepatitis B, an ALT-based algorithm has been developed and higher liver stiffness measurements (LSM) cut-off values for different stages of liver fibrosis should be used in patients with elevated ALT levels up to five times the upper limit of normal. Furthermore, falsely-high LSM results up to the cirrhotic range may occur during ALT flare. TE is also useful predicting patient prognosis in the development of hepatocellular carcinoma (HCC), portal hypertension, postoperative complications in HCC patients and survival. Unfortunately, failed acquisition of TE is common in obese patients. Furthermore, obese patients may have higher LSM results, even in the same stage of liver fibrosis. To better evaluate NAFLD a new XL probe, with a larger probe with lower ultrasound frequency and deeper penetration, increases the success rate of TE in obese patients. The median LSM value with the XL probe was found to be lower than that by the conventional M probe, hence cut-off values were approximately 1.2 to 1.3 kilopascals lower than those of the M probe, suggesting its adoption. Studies reveal that a novel ultrasonic controlled attenuation parameter is potentially useful to detect and quantify hepatic steatosis non-invasively. Conclusion: TE is a non-invasive, accurate and reproducible test of liver fibrosis and possibly hepatic steatosis and has been validated in a wide spectrum of liver diseases. TE is also useful to predict patient outcomes.

Abstract
BACKGROUND/AIMS The noninvasive measurement of liver stiffness using transient elastography (TE) is increasingly being used alongside liver biopsy. However, several conditions may lead to higher liver stiffness values without reflecting more fibrosis. Such conditions (e.g. hepatitis, cholestasis, heart failure, mechanical ventilation) limit the interpretation of liver stiffness measurements. The influence of hemodialysis on the measurement of liver stiffness has not been investigated to date. Here, we analyzed liver stiffness assessed by fibroscan in 17 patients directly before and after a hemodialysis session. PATIENTS AND METHODS Measurement of hepatic stiffness by TE was carried out using the Fibroscan device with the 'M probe' directly before and directly after one session of hemodialysis. Each measurement consisted of at least 10 individual and valid measurements, with a success rate of at least 60%, and an interquartile range of less than 25%. All measurements were carried out by one investigator not involved in patient management. RESULTS Before dialysis, the median TE was 5.1 kPa (2.8-17 kPa). Ten patients had values below the threshold of 7.1 kPa and seven patients had TE>7.1 kPa. The median net fluid withdrawal by hemodialysis was 2.5 l (0.4-3.1 l) and did not differ between patients. After dialysis, the TE median was 7.4 kPa (3.5-12.5 kPa) and had changed in all patients except one. Liver stiffness increased significantly when the initial TE was lower than 7.1 kPa (P=0.05), but not when the initial TE was higher than 7.1 kPa. Furthermore, the magnitude of the change in TE after hemodialysis correlated inversely with the liver stiffness before hemodialysis (P=0.03) and with spleen length measured by ultrasound (P=0.03). CONCLUSION This study is the first to report on the influence of hemodialysis on liver stiffness measurement. In contrast to previous reports, liver stiffness might increase after fluid withdrawal if patients do not show significant fibrosis. We conclude that before dialysis, TE possibly better differentiates between patients with or without significant fibrosis.

Abstract
The discovery and development of biomarkers for fibrotic diseases have potential utility in clinical decision-making as well as in pharmaceutical research and development. This review describes strategies for identifying diagnostic, prognostic and theranostic biomarkers. A range of technologies and platforms for biomarker discovery are highlighted, including several with specific relevance for fibrosis. Some challenges specific to fibrotic diseases are outlined including; benchmarking biomarkers against imperfect clinical measures of fibrosis, the complexity resulting from diverse aetiologies and target organs, and the availability of samples (including biopsy) from well-characterised patients with fibrotic disease. To overcome these challenges collaboration amongst clinical specialities as well as between academia and industry is essential. This article is part of a Special Issue entitled: Fibrosis: Translation of basic research to human disease.

World J Gastroenterol 2013; 19:516-522. [PMID: 23382630 PMCID: PMC3558575 DOI: 10.3748/wjg.v19.i4.516] [Citation(s) in RCA: 47] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2012] [Accepted: 01/10/2013] [Indexed: 02/06/2023] Open
Abstract
AIM: To determine the evolution of transient elastography (TE) in patients with alcoholic liver disease according to alcohol cessation or continuation.
METHODS: We retrospectively selected in our local database all patients who had two TE between June 2005 and November 2010 with chronic alcohol excessive consumption and excluded those with associated cause of liver disease. TE was performed at least one week apart by senior operator. TE examinations with less than ten successful measures or with an interquartile range above 30% were excluded. We retrospectively reviewed file of all patients to include only patient followed up by trained addictologist and for which definite information on alcohol consumption was available. Concomitant biological parameters [aspartate amino transferase (AST), alanine amino transferase and gamma-glutamyl transpeptidase (GGT)] within 4 wk of initial and final TE were recorded. Putative fibrosis score according to initial and final TE were determined with available cut-off for alcoholic liver disease and hepatitis C. Initial and final putative fibrosis score were compared according to alcohol consumption during follow-up.
RESULTS: During the study period 572 patients had TE examination for alcoholic liver disease and 79 of them had at least two examinations. Thirty-seven patients met our criteria with a median follow-up of 32.5 wk. At the end of the study, 13 (35%) were abstinent, and 24 (65%) relapsers. Eight patients had liver biopsy during follow-up. TE decreased significantly during follow-up in 85% of abstinent patients [median (range): -4.9 (-6.1,-1.9)], leading to a modification of the putative fibrosis stage in 28%-71% of patient according to different cut-off value. In relapsers TE increased in 45% and decreased in 54% of patient. There was no statistical difference between initial and final TE in relapsers. In the overall population, using 22.6 kPa as cut-off for cirrhosis, 4 patients had cirrhosis at initial TE and 3 patients had cirrhosis at final TE. Using 19.5 kPa as cut-off for cirrhosis, 7 patients had cirrhosis at initial TE and 5 patients had cirrhosis at final TE. Using 12.5 kPa as cut-off for cirrhosis, 16 patients had cirrhosis at initial TE and 15 patients had cirrhosis at final TE. Evolution of biological data was in accordance with the relapse or abstinent status: abstinence ratio (duration of abstinence/duration follow-up) was correlated with AST ratio (r = -0.465, P = 0.007) and GGT ratio (r = -0.662, P < 0.0001). GGT was correlated with initial (r = 0.488, P = 0.002) and final TE (r = 0.49, P < 0.005). Final TE was correlated with AST (r = 0.362, P < 0.05). Correlation between TE ratio and AST ratio (r = 0.44, P = 0.01) revealed that TE varied proportionally to AST for all patients irrespective of their alcohol status. The same relationship was observed between TE ratio and GGT ratio (r = 0.65, P < 0.0001). Evolution of TE was significantly correlated with the ratio of time of abstinence to observation time (r = -0.387, P = 0.016) and the evolution of liver enzymes.
CONCLUSION: TE significantly decreased with abstinence. Results of TE in alcoholic liver disease cannot be interpreted without taking into account alcohol consumption and liver enzymes.

Abstract
AIM: To compare results of liver stiffness measurements by transient elastography (TE) obtained in our patients population with that used in a recently published meta-analysis.
METHODS: This was a single center cross-sectional study. Consecutive patients with chronic viral hepatitis scheduled for liver biopsy at the outpatient ward of our Infectious Diseases Department were enrolled. TE was carried out by using FibroScan™ (Echosens, Paris, France). Liver biopsy was performed on the same day as TE, as day case procedure. Fibrosis was staged according to the Metavir scoring system. The diagnostic performance of TE was assessed by using receiver operating characteristic (ROC) curves and the area under the ROC curve analysis.
RESULTS: Two hundred and fifty-two patients met the inclusion criteria. Six (2%) patients were excluded due to unreliable TE measurements. Thus, 246 (171 men and 75 women) patients were analyzed. One hundred and ninety-five (79.3%) patients had chronic hepatitis C, 41 (16.7%) had chronic hepatitis B, and 10 (4.0%) were coinfected with human immunodeficiency virus. ROC curve analysis identified optimal cut-off value of TE as high as 6.9 kPa for F≥ 2; 7.9 kPa for F≥ 3; 9.6 kPa for F = 4 in all patients (n = 246), and as high as 6.9 kPa for F≥ 2; 7.3 kPa for F≥ 3; 9.3 kPa for F = 4 in patients with hepatitis C (n = 195). Cut-off values of TE obtained by maximizing only the specificity were as high as 6.9 kPa for F≥ 2; 9.6 kPa for F≥ 3; 12.2 kPa for F = 4 in all patients (n = 246), and as high as 7.0 kPa for F≥ 2; 9.3 kPa for F≥ 3; 12.3 kPa for F = 4 in patients with hepatitis C (n = 195).
CONCLUSION: The cut-off values of TE obtained in this single center study are comparable to that obtained in a recently published meta-analysis that included up to 40 studies.

Abstract
BACKGROUND The present study evaluated performance characteristics of liver stiffness measurement (LSM) by FibroScan in patients with different stages of nonalcoholic fatty liver disease (NAFLD). PATIENTS AND METHODS A total of 307 subjects (120 NAFLD, 85 NAFLD related cirrhosis, and 102 healthy controls) were studied. RESULTS In NAFLD patients, LSM had significant correlation with fibrosis (r = 0.68, p < 0.001), and increased progressively with increasing fibrosis (p < 0.001). However, the difference between stage 1 and stage 2 fibrosis was not significant (p = 0.07). The LSM in NAFLD without fibrosis and healthy controls was similar (p = 0.37). The areas under receiver-operating characteristics (AUROC) curve of LSM for stages ≥1, ≥2, ≥3, and 4 were 0.82, 0.85, 0.94, and 0.96, respectively. The best LSM (kPa) cut-offs for fibrosis stages ≥1, ≥2, ≥3 and 4 were 6.1, 7.0, 9.0, and 11.8, respectively. The negative predictive value of LSM for excluding advanced fibrosis was 95%. For advanced fibrosis, the AUROC curve of LSM was 0.94, followed by FIB-4 (0.75), BARD score (0.68), NAFLD fibrosis score (0.66), and aspartate platelet ratio index (0.60). In multivariate analysis, LSM was the only independent predictor of advanced fibrosis (odds ratio 1.47). In patients with NAFLD cirrhosis, LSM correlated significantly with Child-Pugh score (r = 0.40, p < 0.001), serum bilirubin (r = 0.34, p = 0.02), and grades of esophageal varices (r = 0.23, p = 0.04). CONCLUSION LSM is a useful tool for evaluation of patients with NAFLD, and is the best among other non-invasive predictors of liver fibrosis.

Abstract
OBJECTIVE To evaluate the predictive value of transient elastography (TE), easy available biochemical scores and a combination of these to detect advanced liver fibrosis (i.e. fibrosis stage ≥F3) in patients with chronic liver disease of different etiologies. MATERIAL AND METHODS A valid TE was obtained in 418 patients with chronic liver disease of mixed etiologies during the period of 2007-2010. Reliable fibrosis staging and biochemical data for calculation of APRI, FIB4, and AST/ALT-ratio (AAR) were available in 187 cases of which 50 had clinical obvious cirrhosis. Logistic regression analyses were performed to investigate if biochemical scores were significant predictors of advanced fibrosis independent of TE. RESULTS In the whole group, TE correlated significantly with APRI and FIB4 but not with AAR. In patients with TE ≥7 kPa, a new formula combining TE and FIB4 improved the accuracy for detecting advanced fibrosis. Area under the receiver operating characteristic curve (AUROC) and sensitivity for the combined formula was 0.94 and 0.92, respectively, as opposed to 0.90 and 0.87 for TE alone. After exclusion of cases with clinical obvious cirrhosis, only FIB4 was a significant predictor of advanced liver fibrosis independent of TE. A combined formula gave a marginally improved AUROC in this group. CONCLUSIONS Our findings suggest that the combination of TE and FIB4 is useful in the prediction of advanced fibrosis. The effect of this combination was marginal when only asymptomatic patients were included. Larger studies are needed to see if this effect is statistically significant and to detect possible differences according to etiology.

Abstract
The FIB-4 index is a simple formula to predict liver fibrosis based on the standard biochemical values (AST, ALT and platelet count) and age. We here investigated the utility of the index for noninvasive prediction of progression in liver fibrosis. The time-course alteration in the liver fibrosis stage between paired liver biopsies and the FIB-4 index was examined in 314 patients with chronic hepatitis C. The average interval between liver biopsies was 4.9 years. The cases that showed a time-course improvement in the fibrosis stage exhibited a decrease in the FIB-4 index, and those that showed deterioration in the fibrosis stage exhibited an increase in the FIB-4 index with a significant correlation (P < 0.001). Increase in the ΔFIB-4 index per year was an independent predictive factor for the progression in liver fibrosis with an odds ratio of 3.90 (P = 0.03). The area under the receiver operating characteristic curve of the ΔFIB-4 index/year for the prediction of advancement to cirrhosis was 0.910. Using a cut-off value of the ΔFIB-4 index/year <0.4 or ≥ 0.4, the cumulative incidence of fibrosis progression to cirrhosis at 5 and 10 years was 34% and 59%, respectively in patients with the ΔFIB-4 index/year ≥0.4, whereas it was 0% and 3% in those with the ΔFIB-4 index/year <0.4 (P < 0.001). In conclusion, measurement of the time-course changes in the FIB-4 index is useful for the noninvasive and real-time estimation of the progression in liver fibrosis.

Abstract
Liver stiffness measurement (LSM) is a noninvasive method for the diagnosis of hepatic fibrosis. The aim of this study was to evaluate the effects of hepatitis activity and antiviral therapy on LSM in cirrhotic patients. Consecutive patients with compensated hepatic cirrhosis were enrolled for LSM. The medical records of hepatitis activity and antiviral therapy before enrollment were reviewed. Patients were stratified into inactive, fluctuating, and active groups by serial change of alanine transaminase level. For chronic hepatitis C, patients were stratified into sustained virological response (SVR) and non-SVR (NSVR) by effect of antiviral treatment. LSM results were compared among different groups. A total of 163 patients (mean age = 57.2 ± 11.0 years) were enrolled. The median (range) LSM values were 9.6 (4.2-20.6), 10.25 (3.9-49.6), and 15.75 (4.8-61.5) kPa in the inactive, fluctuating, and active groups, respectively. Patients in the active group had significantly higher LSM values. For chronic hepatitis C, median (range) LSM values were 16.6 (8.1-61.5), 22.9 (11.1-37.4), and 11.2 (3.9-27.0) kPa in patients without antiviral therapy, in NSVR, and in SVR groups, respectively. Patients with SVR had significantly lower LSM values. For chronic hepatitis B, median (range) LSM values were 11.8 (5.1-46.6), 16.85 (4.2-48), and 10.6 (4.3-46.4 kPa) kPa in patients without oral nucleos(t)ide analogue (NA) therapy, with NA < 12, and ≧12 months, respectively. There was a significantly lower LSM value in patients with NA therapy≧12 months. There were low LSM values in cirrhotic patients without hepatitis activity, as well as with SVR in chronic hepatitis C and long-term NA therapy in chronic hepatitis B.

We here report on a 55-year-old patient with drastically increased LS due to previously unknown systemic mastocytosis. The patient initially presented with increased weight loss, nocturnal pruritus, increased transaminases, bilirubinemia, and thrombocytopenia. Abdominal ultrasound showed ascites, hepatomegaly, and splenomegaly. In addition, LS was 75 kPa (IQR 0 kPa) clearly exceeding the cut-off value for F4 cirrhosis of 12.5 kPa. However, histological analysis of the liver specimen indicated liver involvement by systemic mastocytosis and excluded liver cirrhosis. An additional CT scan detected disseminated bone lesions. After three months of treatment with Midostaurin, LS slightly decreased down to 31.9 kPa (IQR 8.3 kPa). This case illustrates that diffused sinusoidal neoplastic infiltrates are a pitfall in the non-invasive diagnosis of liver cirrhosis. In conclusion, refined clinical algorithms for increased LS should also include mastocytosis in addition to inflammation, congestion, and biliary obstruction.

Abstract
BACKGROUND The aim of this study was to describe changes in repeated liver stiffness (LS) measurements and to assess the determinants of increase in LS in HIV-HCV-coinfected patients. METHODS HIV-HCV-coinfected adults enrolled in the ANRS CO 13 HEPAVIH cohort, for whom two results of LS, evaluated over ≥24 months, were available. Patients with unreliable LS results were not included. LS was measured at baseline and every year thereafter. Determinants of LS increase were assessed using linear (primary outcome: last LS minus first LS value) and logistic (secondary outcome: ≥30% increase in the initial LS value) regression analyses. RESULTS A total of 313 patients (mean age 45 years, 67.4% male) were included. Overall, 93.9% were receiving antiretroviral treatment (ART). The mean baseline CD4(+) T-cell count was 471 cells/mm(3) and 72.2% of patients had undetectable plasma HIV RNA. The mean interval between the first and last LS measurements was 33.5 months. No significant difference was found between baseline and follow-up mean LS values (P=0.39). However, a decrease of ≥30% in LS was observed in 48 (15.3%) patients and an increase of ≥30% in 64 (20.5%) patients. In multivariate linear and logistic analyses, excessive alcohol intake (β coefficient 6.8; P=0.0006) and high HCV viral load (OR 1.7, 95% CI 1.1, 2.5; P=0.01) were independently associated with an increase in LS, whereas time on ART>114.5 months (OR 0.5, 95% CI 0.3, 0.9; P=0.03) and achievement of sustained virological response (OR 0.1, 95% CI 0.01, 0.9; P=0.04) were independently associated with no increase in LS. CONCLUSIONS Our findings show that long-term ART and achieving sustained virological response in HIV-HCV-coinfected patients are both significantly associated with lack of increase in LS over a 33-month period.

Abstract
BACKGROUND Transient elastography (TE), a non-invasive tool that measures liver stiffness, has been evaluated in meta-analyses for effectiveness in assessing liver fibrosis in European populations with chronic hepatitis C (CHC). However, these data cannot be extrapolated to populations in Asian countries, where chronic hepatitis B (CHB) is more prevalent. In this study, we performed a meta-analysis to assess the overall performance of TE for assessing liver fibrosis in patients with CHB. METHODS Studies from the literature and international conference abstracts which enrolled only patients with CHB or performed a subgroup analysis of such patients were enrolled. Combined effects were calculated using area under the receiver operating characteristic curves (AUROC) and diagnostic accuracy values of each study. RESULT A total of 18 studies comprising 2,772 patients were analyzed. The mean AUROCs for the diagnosis of significant fibrosis (F2), severe fibrosis (F3), and cirrhosis (F4) were 0.859 (95% confidence interval [CI], 0.857-0.860), 0.887 (95% CI, 0.886-0.887), and 0.929 (95% CI, 0.928-0.929), respectively. The estimated cutoff for F2 was 7.9 (range, 6.1-11.8) kPa, with a sensitivity of 74.3% and specificity of 78.3%. For F3, the cutoff value was determined to be 8.8 (range, 8.1-9.7) kPa, with a sensitivity of 74.0% and specificity of 63.8%. The cutoff value for F4 was 11.7 (range, 7.3-17.5) kPa, with a sensitivity of 84.6% and specificity of 81.5%. CONCLUSION TE can be performed with good diagnostic accuracy for quantifying liver fibrosis in patients with CHB.

Abstract
OBJECTIVE The purpose of this article is to evaluate the diagnostic performance of transient elastography, real-time strain elastography, and aspartate-to-platelet ratio index in assessing fibrosis in patients with chronic hepatitis C by using histologic Metavir scores as reference standard. SUBJECTS AND METHODS Consecutive patients with chronic hepatitis C scheduled for liver biopsy were enrolled. Liver biopsy was performed on the same day as transient elastography and real-time strain elastography. Transient elastography and real-time strain elastography were performed in the same patient encounter by a single investigator using a medical device based on elastometry and an ultrasound machine, respectively. Diagnostic performance was assessed by using receiver operating characteristic curves and area under the receiver operating characteristic curve (AUC) analysis. RESULTS One hundred thirty patients (91 men and 39 women) were analyzed. The cutoff values for transient elastography, real-time strain elastography, and aspartate-to-platelet ratio index were 6.9 kPa, 1.82, and 0.37, respectively, for fibrosis score of 2 or higher; 7.3 kPa, 1.86, and 0.70, respectively, for fibrosis score of 3 or higher; and 9.3 kPa, 2.33, and 0.70, respectively, for fibrosis score of 4. AUC values of transient elastography, real-time strain elastography, aspartate-to-platelet ratio index were 0.88, 0.74, and 0.86, respectively, for fibrosis score of 2 or higher; 0.95, 0.80, and 0.89, respectively, for fibrosis score of 3 or higher; and 0.97, 0.80, and 0.84, respectively, for fibrosis score of 4. A combination of the three methods, when two of three were in agreement, showed AUC curves of 0.93, 0.95, and 0.95 for fibrosis scores of 2 or higher, 3 or higher, and 4, respectively. CONCLUSION Transient elastography, real-time strain elastography, and aspartate-to-platelet ratio index values were correlated with histologic stages of fibrosis. Transient elastography offered excellent diagnostic performance in assessing severe fibrosis and cirrhosis. Real-time elastography does not yet have the potential to substitute for transient elastography in the assessment of liver fibrosis.

Abstract
Alcohol induced liver disease or alcoholic liver disease (ALD), a complex trait, encompasses a gamut of pathophysiological alterations in the liver due to continuous exposure to a toxic amount of alcohol (more than 80 g per day). Of all chronic heavy drinkers, only 15-20% develops hepatitis or cirrhosis concomitantly or in succession. Several studies revealed that inter-individual as well as inter-ethnic genetic variation is one of the major factors that predispose to ALD. The role of genetic factors in ALD has long been sought for in ethnically distinct population groups. ALD is fast emerging as an important cause of chronic liver disease in India; even in populations such as "Bengalis" who were "culturally immune" earlier. While the genetic involvement in the pathogenesis of ALD is being sought for in different races, the complex pathophysiology of ALD as well as the knowledge of population level diversity of the relevant alcohol metabolizing and inflammatory pathways mandates the need for well designed studies of genetic factors in ethnically distinct population groups. An array of cytokines plays a critical role as mediators of injury, inflammation, fibrosis and cirrhosis in ALD. We, therefore, studied the association of polymorphisms in five relevant cytokine genes with "clinically significant" ALD in an ethnic "Bengali" population in Eastern India. Compared with "alcoholic" controls without liver disease (n=110), TNFα -238AA genotype, IL1β -511CC genotype, TGFβ1 -509CC genotype and IL10 -592AA genotype were significantly overrepresented in ALD patients (n=181; OR=2.4 and 95% CI 1.2-5.5, P(genotype)=0.042, P(allelic)=0.008; OR=2.7 and 95% CI 1.2-5.9, P(genotype)=0.018, P(allelic)=0.023; OR=4.7 and 95% CI 1.7-13.1, P(genotype)=0.003, P(allelic)=0.014; and OR=2.2 and 95% CI 1.1-4.8, P(genotype)=0.04, P(allelic)=0.039 respectively). Moreover a cumulative genetic risk analysis revealed a significant trend for developing ALD with an increase in the number of risk alleles on IL10 and TGFβ1 loci among alcoholics. The risk genotype of IL1β and TGFβ1 also influences the total bilirubin, albumin and alanine aminotransferase levels among alcoholic "Bengalis". The present study is the first case-control study from Eastern India that comprehensively identified polymorphic markers in TNFα, IL10, IL1β and TGFβ1 genes to be associated with ALD in the Bengali population, accentuating the significance of genetic factors in clinical expressions of ALD.

Abstract
BACKGROUND AND AIMS Establishing the presence of fibrosis and cirrhosis is an essential step in the management of patients with chronic liver diseases (CLD). Liver stiffness measurement (LSM) based on transient elastography (TE) correlates well with the stages of liver fibrosis and has been developed as a non-invasive alternative to liver biopsy. The studies performed to date have used physician operators. With the potential use of TE for screening of community-based populations for liver disease, we aimed to evaluate the performance of nurse operators. DESIGN Retrospective analysis. METHODS We reviewed the reliability and accuracy of LSMs performed by the nurse-led TE service at Queen's Medical Centre, Nottingham between May 2009 and January 2011. Consecutive patients with suspected CLD who underwent LSM were included. RESULTS Over the study period 585 LSMs were performed. Analysis was performed on the 208 patients where LSM could be compared with liver biopsy findings. Of these 11 (5.3%) had unreliable LSM results (less than 10 valid shots or success rate <60%). There were no LSM failures. Inadequate liver biopsy specimen led to exclusion in 26 (12.5%) patients. For the detection of significant fibrosis (Ishak stage >2), a sensitivity of 0.78 and specificity of 0.81 was obtained, with a cut-off value of 8 kPa. Using a cut-off value of 13 kPa for detection of cirrhosis, a sensitivity and specificity of 0.8 and 0.92 was obtained. CONCLUSION We have demonstrated that a nurse-led TE service can produce a low level of unreliable results and LSM failures, with comparable sensitivity and specificity for detecting significant fibrosis and cirrhosis to those reported in the literature. The demands on the use of TE could potentially be eased through the introduction of nurse-led service delivery.

Abstract
BACKGROUND & AIMS Our aim was to evaluate a serologic marker (ELF) and two ultrasound-based methods (FibroScan and ARFI), as well as their combinations, in the assessment of liver fibrosis. METHODS One-hundred and forty-six patients (87 liver transplant recipients, 59 non-transplant patients) who underwent liver biopsy were prospectively included. We evaluated the diagnostic accuracy of FibroScan, ARFI, ELF and the combination of ELF with either ARFI or FibroScan. After analyzing in separate transplant and non-transplant patients, the whole cohort was divided into a training set and a validation set. RESULTS ARFI imaging was successfully performed across the whole cohort, while FibroScan failed in 16 (11%) patients. The three methods showed similar AUROCs and best cut-off values in transplant and non-transplant patients. In the training set, differences between the AUROCs of ARFI, FibroScan and ELF to diagnose F⩾2 (0.879, 0.861, and 0.764, respectively) and cirrhosis (0.936, 0.918, and 0.841) were not statistically significant, although both ultrasound-based methods showed higher accuracy than ELF. The combination of ELF with ARFI or FibroScan increased the negative and positive predictive values of single tests for the diagnosis of F ≥ 2 and cirrhosis. Similar results were obtained when the methods were tested in the validation set. CONCLUSIONS ARFI is as effective as either FibroScan or ELF in the non-invasive assessment of liver fibrosis, and its inclusion in an ultrasound device could facilitate its incorporation into routine clinical practice. The combination of ARFI or FibroScan with ELF may help better identify patients with or without significant fibrosis or cirrhosis.

Abstract
BACKGROUND FibroScan is one of the noninvasive techniques based on the transient elastography that can assess the progression of liver fibrosis in chronic hepatitis patients in daily clinical practice. Recently, LecT-Hepa was validated as a serological glycomarker correlating well with the fibrosis stage determined by liver biopsy, and was superior to many other noninvasive biochemical markers and tests. We compared the reliability of LecT-Hepa with that of FibroScan for evaluation of liver fibrosis. METHODS The effects of increased alanine aminotransferase (ALT) activities on LecT-Hepa and FibroScan were investigated. RESULTS The areas under the receiver-operating characteristic curves, sensitivity and specificity for detecting cirrhosis, which is one of the outcomes of fibrosis estimation, were 0.82, 72.5% and 78.2% of LecT-Hepa, 0.85, 87.0% and 74.1% of FibroScan; these did not differ significantly. The count distribution of LecT-Hepa in non-cirrhosis group or cirrhosis group did not differ between the patients grouped according to their ALT levels, whereas that of FibroScan was substantially affected. CONCLUSION LecT-Hepa was confirmed as a reliable noninvasive test for the evaluation of liver fibrosis in hepatitis B virus-infected patients with comparable performance to that of FibroScan and proved to be unaffected by inflammation.

Abstract
BACKGROUND The purpose of this study was to investigate whether preoperative liver stiffness measurement (LSM) can predict recurrence after curative resection of hepatocellular carcinoma (HCC). LSM using FibroScan(®) can assess the severity of liver fibrosis, which is significantly associated with recurrence after curative resection of HCC. METHODS Between February 2006 and March 2009, 133 patients who underwent preoperative LSM and curative resection for HCC were enrolled in this prospective study. LSM values were analyzed for association with recurrence, together with other clinical variables. RESULTS The mean age of the patients (117 men and 16 women) was 57 years. During the follow-up period (median, 25.0 (range, 3.0-54.6) months), HCC recurred in 62 (46.6 %) patients. In multivariate analysis, together with satellite nodule and Edmonson-Steiner grade III-IV, LSM was selected as an independent predictor of recurrence (P < 0.05; hazard ratio, 1.034; 95 % confidence interval, 1.007-1.061). When the study population was stratified into two groups using the optimal cutoff value (13.4 kPa) that maximized the sum of sensitivity (64.7 %) and specificity (76.1 %) from time-dependent receiver operating characteristic curves (area under the receiver operating characteristic curve = 0.676), patients with LSM values >13.4 kPa were at a significantly greater risk for recurrence with a hazard ratio of 1.925 (P = 0.01; 95 % confidence interval, 1.17-3.168) compared with those with LSM values ≤ 13.4 kPa. CONCLUSIONS Our data suggest that LSM can be a useful predictor of recurrence after curative resection of HCC.

Abstract
UNLABELLED Our aim was to assess the predictive value of liver stiffness (LS), measured by transient elastography (TE), for clinical outcome in human immunodeficiency virus / hepatitis C virus (HIV/HCV)-coinfected patients with compensated liver cirrhosis. This was a prospective cohort study of 239 consecutive HIV/HCV-coinfected patients with a new diagnosis of cirrhosis, done by TE, and no previous decompensation of liver disease. The time from diagnosis to the first liver decompensation and death from liver disease, as well as the predictors of these outcomes, were evaluated. After a median (Q1-Q3) follow-up of 20 (9-34) months, 31 (13%, 95% confidence interval [CI]: 9%-17%) patients developed a decompensation. The incidence of decompensation was 6.7 cases per 100 person-years (95% CI, 4.7-9-6). Fourteen (8%) out of 181 patients with a baseline LS < 40 kPa developed a decompensation versus 17 (29%) out of 58 with LS ≥ 40 kPa (P = 0.001). Factors independently associated with decompensation were Child-Turcotte-Pugh (CTP) class B versus A (hazard ratio [HR] 7.7; 95% CI 3.3-18.5; P < 0.0001), log-plasma HCV RNA load (HR 2.1; 95% CI 1.2-3.6; P = 0.01), hepatitis B virus coinfection (HR, 10.3; 95% CI, 2.1-50.4; P = 0.004) and baseline LS (HR 1.03; 95% CI 1.01-1.05; P = 0.02). Fifteen (6%, 95% CI: 3.5%-9.9%) patients died, 10 of them due to liver disease, and one underwent liver transplantation. CTP class B (HR 16.5; 95% CI 3.4-68.2; P < 0.0001) and previous exposure to HCV therapy (HR 7.4; 95% CI 1.7-32.4, P = 0.007) were independently associated with liver-related death; baseline LS (HR 1.03; 95% CI 0.98-1.07; P = 0.08) was of borderline significance. CONCLUSION LS predicts the development of hepatic decompensations and liver-related mortality in HIV/HCV-coinfection with compensated cirrhosis and provides additional prognostic information to that provided by the CTP score.

Abstract
BACKGROUND Liver stiffness measurement (LSM) using transient elastography (FibroScan) can accurately assess the degree of liver fibrosis and predict the development of hepatocellular carcinoma (HCC) and variceal bleeding in patients with chronic hepatitis B (CHB). AIMS We compared the accuracy of noninvasive liver fibrosis prediction methods in predicting the development of HCC or hepatic decompensation in patients with CHB. METHODS A total of 1126 patients with CHB who underwent LSMs and attended regular follow-ups to detect the development of HCC and hepatic decompensations (variceal bleeding, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, or hepatorenal syndrome) were enrolled. Noninvasive liver fibrosis prediction methods included, age-spleen-to-platelet ratio index, LSM, LSM-spleen diameter-to-platelet ratio index (LSPI), P2/MS, and FIB-4. RESULTS During follow-up (median, 30.7 mo), HCC and hepatic decompensation developed in 63 and 68 patients, respectively. The accuracy of LSM and LSPI in predicting the development of HCC or hepatic decompensation was higher than that of aspartate aminotransferase-to-platelet ratio index, age-spleen-to-platelet ratio index, P2/MS, or FIB-4 (areas under the receiver operating characteristic curve=0.789 and 0.788 vs. 0.729, 0.756, 0.696, and 0.744 for HCC development; areas under the receiver operating characteristic curve=0.820 and 0.848 vs. 0.787, 0.799, 0.812, and 0.784 for hepatic decompensation). On multivariate analyses, LSM and LSPI were identified as independent predictors of the development of HCC [hazard ratio (HR), 1.040 (LSM); HR, 1.001 (LSPI)] and hepatic decompensation [HR, 1.033 (LSM); HR, 1.002 (LSPI)]. CONCLUSIONS Our results suggest that LSM or LSPI may be useful predictors of the development of HCC and hepatic decompensation in patients with CHB.

Abstract
AIM: To evaluate the efficacy of autologous bone marrow stem cell transplantation in the treatment of decompensated cirrhosis by Fibroscan combined with multiple parameters.
METHODS: A total of 58 patients with decompensated cirrhosis were divided into transplantation group (n = 27) and control group (n = 31). Baseline examinations, including liver biopsy and Fibroscan, were performed before therapy. Both groups underwent routine medical treatment, and the transplantation group additionally underwent autologous bone marrow stem cell transplantation. At 2, 4, 8, 12, 24 and 48 wk after therapy, liver function and coagulation function were measured. Fibroscan and FIB-4 tests were performed at 12, 24 and 48 wk. At 48 wk after therapy, some patients underwent a liver biopsy. Then the efficacy of autologous bone marrow stem cell transplantation in the treatment of cirrhosis and the role of Fibroscan in evaluation of the curative effect were analyzed comprehensively.
RESULTS: Successful transplantation was achieved in all the 27 patients. Seven patients from each group underwent a liver biopsy, and they were clearly diagnosed with cirrhosis by histopathology. At 8 wk after therapy, the improvement in symptoms and physical signs in the transplantation group was better than that in the control group. The liver function and coagulation function improved in both groups, and the improvement was more significant in the transplantation group than in the control group. The liver stiffness values in the transplantation group did not differ significantly between before treatment and 12 and 24 wk after transplantation (31.66 kPa ± 6.97 kPa vs 31.98 kPa ± 7.36 kPa, 31.35 kPa ± 6.73 kPa, both P > 0.05), but were significantly higher at 48 wk than at other time points (31.78 kPa ± 7.35 kPa, P < 0.05). The liver stiffness values in the control group increased gradually from 32.05 kPa ± 9.09 kPa at pretreatment to 36.39 kPa ± 9.39 kPa at 48 wk after therapy (P < 0.05), and there was a statistical difference in the liver stiffness values between the two groups at 48 wk. The level of HA in the transplantation group decreased more significantly than that in the control group (P < 0.05 at 24 wk).
CONCLUSION: Autologous bone marrow stem cell transplantation can significantly improve symptoms and liver function in patients with decompensated cirrhosis. Fibroscan is an important means of evaluating the curative effect of autologous bone marrow stem cell transplantation on decompensated cirrhosis.

Abstract
AIM: To evaluate the role of Fibroscan (FS) in the diagnosis of liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD).
METHODS: A total of 83 patients who were pathologically diagnosed with NAFLD and underwent liver stiffness measurement using FibroScan at Beijing Youan Hospital from April 2008 to February 2011 were included in this study. Staging of liver fibrosis based on a liver biopsy was performed in all patients. Other clinical tests included liver function, FBG, blood lipids and UA The correlation between liver stiffness and liver fibrosis degree was analyzed. The receive operating characteristic (ROC) curve was used to analyze the accuracy of Fibroscan in diagnosing liver fibrosis with NAFLD.
RESULTS: The liver stiffness differed among patients with different stages of liver fibrosis. The Fibroscan values were 4.28 kPa ± 1.32 kPa, 7.40 kPa ± 2.13 kPa, 11.52 kPa ± 3.86 kPa, and 19.99 kPa ± 5.42 kPa for patients with S0 to S3 liver fibrosis, respectively, and liver stiffness was closely related to stage of liver fibrosis (r = 0.768, P < 0.001). Fibroscan score was positively correlated with ALT and AST, but negatively with HDL and ApoA (all P < 0.05). The area under the ROC curve for FibroScan score in assessing liver fibrosis was 0.889 (0.813, 0.965) in patients with S1 liver fibrosis, 0.838 (0.729, 0.948) in those with S2, and 0.938 (0.000, 1.000) in those with S3. The cut off values were 8.95 kPa, 10.60 kPa and 15.66 kPa, respectively.
CONCLUSION: Fibroscan is valuable for the diagnosis of liver fibrosis in patients with NAFLD.

Abstract
Background Liver stiffness measurement (LSM) using transient elastography (FibroScan®) can assess liver fibrosis noninvasively. This study investigated whether LSM can predict the development of liver-related events (LREs) in chronic hepatitis B (CHB) patients showing histologically advanced liver fibrosis. Methods Between March 2006 and April 2010, 128 CHB patients with who underwent LSM and liver biopsy (LB) before starting nucleot(s)ide analogues and showed histologically advanced fibrosis (≥F3) with a high viral loads [HBV DNA ≥2,000 IU/mL] were enrolled. All patients were followed regularly to detect LRE development, including hepatic decompensation (variceal bleeding, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, hepatorenal syndrome) and hepatocellular carcinoma (HCC). Results The mean age of the patient (72 men, 56 women) was 52.2 years. During the median follow-up period [median 27.8 (12.6–61.6) months], LREs developed in 19 (14.8%) patients (five with hepatic decompensation, 13 with HCC, one with both). Together with age, multivariate analysis identified LSM as an independent predictor of LRE development [P<0.044; hazard ratio (HR), 1.038; 95% confidence interval (CI), 1.002–1.081]. When the study population was stratified into two groups using the optimal cutoff value (19 kPa), which maximized the sum of sensitivity (61.1%) and specificity (86.2%) from a time-dependent receiver operating characteristic curve, patients with LSM>19 kPa were at significantly greater risk than those with LSM≤19 kPa for LRE development (HR, 7.176; 95% CI, 2.257–22.812; P = 0.001). Conclusion LSM can be a useful predictor of LRE development in CHB patients showing histologically advanced liver fibrosis.

Abstract
In this review we summarize the role of liver biopsy, transient elastography and hepatic venous pressure gradient (HVPG) in the diagnosis and monitoring of patients with liver cirrhosis. Transient elastography is useful for the non-invasive diagnosis of cirrhosis, but relevant information is lost if it is used as a dichotomous test. The development of clinically significant portal hypertension (defined as a hepatic venous pressure gradient ≥ 10 mmHg) is associated with the development of varices and decompensation and it is something that it is worth testing for. Transient elastography has some value for the prediction of clinically significant portal hypertension, but a large proportion of patients have non-diagnostic values. It has also some value for the diagnosis of varices, but non-invasive markers cannot substitute endoscopic screening in cirrhosis. Better dynamic, easily repeatable non-invasive tools are needed to monitor compensated cirrhosis.

Abstract
Transient elastography (TE) reliably predicts the severity of recurrent hepatitis C virus after orthotopic liver transplantation (OLT); however, its accuracy in evaluating nonviral liver graft damage is unknown. Between 2006 and 2009, 69 OLT recipients [37 for hepatitis B virus/hepatitis D virus (recurrence-free), 20 for autoimmune/cholestatic liver disease, 6 for alcoholic liver disease, and 6 for mixed etiologies] underwent protocol/on-demand liver biopsy (LB) and concomitant TE. A histological diagnosis of graft disease was made according to criteria defined by the Banff working group. Sixty-five patients (94%) had reliable TE examinations during a median post-OLT follow-up of 18 months (range = 7-251 months). LB samples (median length = 35 mm) showed graft damage in 28 patients (43%): idiopathic chronic hepatitis (11), steatohepatitis (3), rejection (3), cholangitis (2), and autoimmune/cholestatic recurrence (9). Patients with graft damage had significantly higher serum liver enzyme levels and TE results (median = 7.8 kPa, range = 5.4-27.4 kPa) than the 37 patients without graft damage (median = 5.3 kPa, range = 3.1-7.4 kPa, P < 0.001). By a receiver operating characteristic curve analysis, 2 TE cutoffs for the diagnosis of graft damage were identified: 5.3 kPa with 100% sensitivity and 7.4 kPa with 100% specificity. The pretest probability of graft damage was 43%; in patients with TE values ≤5.3 kPa, the posttest probability of graft damage fell to 0%, but in patients with TE results >7.4 kPa, the posttest probability increased to 100%. In conclusion, the dual TE cutoff allows accurate discrimination between the absence and presence of nonviral liver graft damage and improves the clinical management of OLT recipients in terms of the selection of patients most in need of LB.

Abstract
The prognosis and management of patients with chronic viral hepatitis B and C depend on the amount and progression of liver fibrosis and the risk for cirrhosis. Liver biopsy, traditionally considered to be the reference standard for staging of fibrosis, has been challenged over the past decade by the development of noninvasive methodologies. These methods rely on distinct but complementary approaches: a biologic approach, which quantifies serum levels of biomarkers of fibrosis, and a physical approach, which measures liver stiffness by ultrasound or magnetic resonance elastography. Noninvasive methods were initially studied and validated in patients with chronic hepatitis C but are now used increasingly for patients with hepatitis B, reducing the need for liver biopsy analysis. We review the advantages and limitations of the noninvasive methods used to manage patients with chronic viral hepatitis B or C infection.

Abstract
A novel controlled attenuation parameter (CAP) has been developed for Fibroscan(®) to assess liver steatosis, simultaneously with liver stiffness measurement (LSM). We assessed CAP diagnostic accuracy in a large cohort of patients with chronic hepatitis C (CHC) virus. A total of 615 patients with CHC, who underwent both Fibroscan(®) and liver biopsy, were analysed. Fibrosis was graded using METAVIR score. Steatosis was categorized by visual assessment as S(0) : steatosis in <10% of hepatocytes, S(1) : 11-33%, S(2) : 34-66% and S(3) : 67-100%. Performances of CAP and liver stiffness were determined using receiver operating characteristic (ROC) curve analysis and cross-validated using the bootstrap method. The Obuchowski measure was used to assess overall accuracy of CAP and to differentiate between steatosis grades. In multivariate analysis, CAP was related to steatosis (P < 10(-15) ) independently of fibrosis stage (which was related to LSM). The areas under ROC curves using CAP to detect steatosis were 0.80 (95% CI, 0.75-0.84) for S ≥ S(1) , 0.86 (0.81-0.92) for S ≥ S(2) and 0.88 (0.73-1) S = S(3) . CAP exhibited a good ability to differentiate steatosis grades (Obuchowski measure = 0.92). Performance of LSM for fibrosis assessment confirmed results from previous studies. CAP is a novel tool to assess the degree of steatosis and both fibrosis and steatosis can be evaluated noninvasively during the same procedure using Fibroscan(®) , in patients with CHC.

Abstract
BACKGROUND Measurement of liver stiffness (LS) using real-time elastography appears as a promising tool to evaluate the severity of chronic liver diseases. Previous studies in patients with alcoholic liver disease have suggested that fibrosis was the only histological parameter to influence LS. To challenge this hypothesis, we have prospectively tested the short-term impact of alcohol withdrawal on LS value. METHODS Patients hospitalized for alcohol withdrawal in our Liver and Addiction Unit between 2007 and 2010 had an LS determination at entry (D0) and 7 days after alcohol withdrawal (D7). LS value was given as the median of 10 measurements performed with a FibroScan(®) device. For a given patient, variation of LS was considered as significant when the comparison of the 10 measurements at D0 and at D7 yielded a p-value under 0.05 (Wilcoxon test). RESULTS One hundred and thirty-seven patients were included in the study (median alcohol consumption: 150 g/d; hepatitis C: n = 21 [15.6%]). Considering all patients, median LS value decreased from 7.2 to 6.1 kPa between D0 and D7 (p = 0.00001, paired Wilcoxon test). LS decreased significantly in 62 patients (45.3%), and there was a reduction in the estimated stage of fibrosis in 32 (23.3%). LS increased significantly in 16 patients (11.7%). Subgroup analyses revealed that the decrease in LS was still significant in patients with or without hepatitis C infection, and aspartate transaminase level below or above 100 UI/l. CONCLUSIONS LS decreases significantly in nearly half of heavy drinkers after only 7 days of abstinence. This result strongly suggests that nonfibrotic lesions (such as the presence of alcoholic hepatitis) may influence LS. From a practical point of view, it also shows that variation of alcohol consumption must be taken into account for the interpretation of LS value.

Abstract
The noninvasive measurement of liver stiffness (LS) was evaluated by transient elastography (FibroScan) and the possible influencing factors from the patients' clinical situations including age, gender, liver inflammation represented by alanine transaminase (ALT) and total billirubin (TBIL) level, HBV replication (HBV DNA loads), portal vein pressure (portal vessel diameter, PVD), splenic thickness (SPT) and body mass index (BMI) were analyzed in patients with chronic hepatitis B (CHB). A total of 466 patients including 31 patients with acute-on-chronic liver failure (ACLF), and 435 patients with chronic hepatitis B (CHB) among which 82 patients were diagnosed with liver cirrhosis (LC) by clinical manifestations and liver B-type ultrasonic inspection were enrolled at Tongji Hospital from April to December 2009. LS was measured by a FibroScan device (EchoSens, France). Simultaneously, ALT and TBIL levels, HBV DNA loads, PVD, SPT and BMI in all patients were also tested. Forty-one healthy volunteers served as controls. The values of LS were correlated positively with ages of CHB patients and significantly higher in males than in females. In patients with BMI>28 kg/m(2) (obesity) and abnormal levels of ALT and TBIL, LS values were significantly increased as compared with those having normal levels of ALT and TBIL. The patients with ACLF had the highest LS value. Furthermore, LS values in the patients with LC were significantly higher than those in patients without LC. It is concluded that noninvasive measurement of liver fibrosis by FibroScan provides an alternative method to evaluate liver fibrosis of patients with CHB. In order to properly illustrate the stiffness value taken by transient elastography, patients' gender should be taken into consideration and it is also suggested to avoid possible influencing factors including liver inflammation (high levels of ALT and TBIL) and obesity (high BMI).

Abstract
BACKGROUND/AIM Transient elastography (TE) of liver and hepatic venous pressure gradient (HVPG) allows accurate prediction of cirrhosis and its complications in patients with chronic liver disease. There is no study on prediction of minimal hepatic encephalopathy (MHE) using TE and HVPG in patients with cirrhosis. PATIENTS AND METHODS Consecutive cirrhotic patients who never had an episode of hepatic encephalopathy (HE) were enrolled. All patients were assessed by psychometry (number connection test (NCT-A and B), digit symbol test (DST), serial dot test (SDT), line tracing test (LTT)), critical flicker frequency test (CFF), TE by FibroScan and HVPG. MHE was diagnosed if there were two or more abnormal psychometry tests (± 2 SD controls). RESULTS 150 patients with cirrhosis who underwent HVPG were screened; 91 patients (61%, age 44.0 ± 11.4 years, M:F:75:16, Child's A:B:C 18:54:19) met the inclusion criteria. Fifty three (58%) patients had MHE (Child A (7/18, 39%), Child B (32/54, 59%) and Child C (14/19, 74%)). There was no significant difference between alanine aminotranferease (ALT), aspartate aminotransferase (AST) and total bilirubin level in patients with MHE versus non MHE. Patients with MHE had significantly lower CFF than non MHE patients (38.4 ± 3.0 vs. 40.2 ± 2.2 Hz, P = 0.002). TE and HVPG in patients with MHE did not significantly differ from patients with no MHE (30.9 ± 17.2 vs. 29.8 ± 18.2 KPas, P = 0.78; and 13.6 ± 2.7 vs. 13.6 ± 3.2 mmHg, P = 0.90, respectively).There was significant correlation of TE with Child's score (0.25, P = 0.01), MELD (0.40, P = 0.001) and HVPG (0.72, P = 0.001) while no correlation with psychometric tests, CFF and MHE. CONCLUSION TE by FibroScan and HVPG cannot predict minimal hepatic encephalopathy in patients with cirrhosis.

Abstract
To investigate the dynamic changes of liver stiffness measurement (LSM) by FibroScan(®) and improve its diagnostic accuracy, we studied patients with chronic hepatitis B undergoing acute exacerbation. Eighty-nine treatment naïve patients were enrolled, and Fibroscan(®) was performed every 7-10 days during hospitalization and every 1∼3 months for follow-up. Haematology and liver functions were tested in parallel. Liver biopsies were performed in 23 patients. A total of 282 LSMs were performed. LSM was positively correlated with both alanine aminotransferase (ALT) (r = 0.321, P < 0.001) and bilirubin levels (r = 0.626, P < 0.001). Mean reduction in LSMs in patients along with ALT or bilirubin normalization was significantly greater than those without ALT or bilirubin normalization(P = 0.001, P = 0.038, respectively). In 23 patients with initial LSMs in the range usually defined as indicating cirrhosis (i.e.>18.2 kPa), only 5 were diagnosed with cirrhosis by histopathology or ultrasonography. As ALT normalized, LSMs remained over 12.0 kPa in all these 5 patients. However, in 18 other patients without cirrhosis at baseline, LSMs still remained above 12.0kPa in 10 patients and decreased to below 12.0 kPa in the other 8 patients. LSMs decreased in parallel with ALT and bilirubin normalization. LSM performed after ALT and bilirubin normalization may improve the accuracy in diagnosing cirrhosis in patients with exacerbations of hepatitis B.

Abstract
AIM To investigate the value of liver stiffness in diagnosing hepatocellular carcinoma (HCC) among patients with viral hepatitis, and to prospectively investigate relationships between liver stiffness and HCC development. METHODS Liver stiffness was measured by transient elastography for 157 patients with viral hepatitis, along with various other parameters potentially associated with HCC. HCC was initially present in 41 patients and absent in 116 patients, of whom 106 patients were followed prospectively for HCC development. Diagnostic performances of liver stiffness and other clinical parameters in predicting presence of HCC were evaluated using receiver operating characteristic (ROC) curves and area under the ROC curve (AUROC). RESULTS Liver stiffness was significantly higher in patients with HCC (24.9 ± 19.5 kPa) than in patients without HCC (10.9 ± 8.4 kPa; P < 0.0001). Age (P < 0.0001), platelet cell count (P = 0.0001), prothrombin activity (P = 0.0009), alpha fetoprotein (P = 0.0091), and des-gamma-carboxy prothrombin (DCP) (P = 0.0099) also differed significantly between patients with and without HCC. The largest AUROC was for liver stiffness. Differences between liver stiffness and age, platelet cell count, prothrombin activity, and DCP were not significant, but the AUROC of liver stiffness was superior to that of alpha fetoprotein (P = 0.03850). Using a cut-off liver stiffness of 12.5 kPa, development of HCC was identified in 10 of the 106 patients followed. Multivariate analysis identified liver stiffness ≥12.5 kPa, age ≥60 years, and serum total bilirubin ≥1.0 mg/dL as significantly correlated with development of HCC. CONCLUSIONS Liver stiffness as measured by transient elastography is a predictor of HCC development in viral hepatitis.

Abstract
Liver fibrosis has been gaining noticeable attention because it may lead to end-stage liver cirrhosis and ultimately to hepatocellular carcinoma. Thus, a precise estimation of the degree of liver fibrosis is crucial for predicting prognosis and deciding management of patients with chronic liver diseases. Many non-invasive approaches for the evaluation of liver fibrosis have been developed. Among these procedures, transient elastography has recently drawn great attention. Transient elastography has been reported to be well correlated with the degree of liver fibrosis by many investigators and various institutions. Since the degree of liver fibrosis is considered as a strong predictor of risk for hepatocellular carcinoma development, several trials have been performed to verify the usefulness of measurement of liver stiffness to predict the emergence of hepatocellular carcinoma. From these studies, transient elastography seems to be a promising procedure to predict the risk of hepatocellular carcinoma; however, further cohorts with long-term monitoring of liver stiffness are needed to confirm the usefulness of this method.

Abstract
The findings of several studies suggest that liver stiffness values can be affected by the degree of intrahepatic congestion respiration influence intrahepatic blood volume and may affect liver stiffness. We evaluated the influence of respiration on liver stiffness. Transient elastography (TE) was performed at the end of inspiration and at the end of expiration in patients with chronic liver disease. The median values obtained during the inspiration set and during the expiration set were defined as inspiratory and expiratory liver stiffness, respectively. A total of 123 patients with chronic liver disease were enrolled (mean age 49years; 64.2% men). Liver cirrhosis coexisted in 29 patients (23.6%). Expiratory liver stiffness was significantly higher than inspiratory liver stiffness (8.7 vs 7.9kPa, P=0.001), while the expiratory interquartile range/median ratio (IQR ratio) did not differ from the inspiratory IQR ratio. Expiratory liver stiffness was significantly higher than inspiratory liver stiffness in 49 (39.8%) patients (HE group), expiratory liver stiffness was significantly lower than inspiratory stiffness in 15 (12.2%) patients, and there was no difference in 59 (48.0%) patients. Liver cirrhosis was more frequent in those who had a lower liver stiffness reading in expiration, and only the absence of liver cirrhosis was significantly associated with a higher reading in expiration in multivariate analysis. In conclusion, liver stiffness was significantly elevated during expiration especially in patients without liver cirrhosis. The effect of respiration should be kept in mind during TE readings.

Abstract
BACKGROUND Transient elastography has gained popularity to stage liver fibrosis in chronic viral hepatitis, however, diagnostic cut-offs for severe fibrosis in chronic hepatitis B are poorly defined. AIM To evaluate an algorithm with two distinct cut-offs for positive and negative prediction of significant fibrosis and cirrhosis in chronic hepatitis B patients. METHODS Two cohorts of treatment-naïve patients with chronic hepatitis B (125 training and 92 validations) were consecutively and concurrently examined by percutaneous liver biopsy and transient elastography. Fibrosis was staged by Metavir (significant fibrosis = F ≥ 2; cirrhosis = F4) in ≥ 2 cm long liver tissue cores. RESULTS A >13.1 kPa positive and a ≤ 9.4 kPa negative cut-off for cirrhosis had a >90% sensitivity and specificity, with an accuracy of 94%. The corresponding cut-offs for F ≥ 2 were >9.4 and ≤ 6.2 kPa, thus classifying 56% of patients with an overall accuracy of 90%. In the validation cohort, F4 and F ≥ 2 were predicted by the above transient elastography cut-offs with an overall accuracy >90%. In 165 patients with higher than upper limit of normal transaminase activity the dual cut-off algorithm of transient elastography was as accurate as in the 52 patients with normal alanine aminotransferase values in the prediction and exclusion of cirrhosis, only. CONCLUSIONS A dual cut-off algorithm allowed for correctly classifying both significant fibrosis and cirrhosis in the majority of the patients with chronic hepatitis B, independent of alanine aminotransferase values, thus reducing the need for liver biopsy investigations.

Abstract
OBJECTIVE We wanted to identify the geographic differences in hepatic fibrosis and their associations with the atrophy-hypertrophy complex in patients with chronic viral hepatitis using the dual-contrast material-enhanced MRI (DC-MRI) with gadopentetate dimeglumine and ferucarbotran. MATERIALS AND METHODS Patients with chronic C (n = 22) and B-viral hepatitis (n = 35) were enrolled for determining the subjective grade of fibrosis (the extent and thickness of fibrotic reticulations) in the right lobe (RL), the caudate lobe (CL), the medial segment (MS) and the lateral segment (LS) of the liver, with using a 5-grade scale, on the gradient echo T2(*)-weighted images of DC-MRI. The fibrosis grades of different segments were compared using the Kruskal-Wallis test followed by post-hoc analysis to establish the segment-by-segment differences. The incidences of two pre-established morphologic signs of cirrhosis were also compared with each other between the two groups of patients. RESULTS There were significant intersegmental differences in fibrosis grades of the C-viral group (p = 0.005), and the CL showed lower fibrosis grades as compared with the grades of the RL and MS, whereas all lobes were similarly affected in the B-viral group (p = 0.221). The presence of a right posterior hepatic notch was significantly higher in the patients with intersegmental differences of fibrosis between the RL and the CL (19 out of 25, 76%) than those without such differences (6 out of 32, 19%) (p < 0.001). An expanded gallbladder fossa showed no significant relationship (p = 0.327) with the segmental difference of the fibrosis grades between the LS and the MS. CONCLUSION The relative lack of fibrosis in the CL with more advanced fibrosis in the RL can be a distinguishing feature to differentiate chronic C-viral hepatitis from chronic B-viral hepatitis and this is closely related to the presence of a right posterior hepatic notch.

Abstract
BACKGROUND Liver stiffness assessed using transient elastography is described as a potential risk factor for hepatocellular carcinoma (HCC) in cirrhosis. However, the strict assessment of hepatic parenchymal areas uninvolved with HCC has not been investigated. AIM To determine if liver stiffness of nonmalignant hepatic parenchyma using magnetic resonance elastography (MRE) is higher in patients with HCC compared with controls. METHODS Cases were defined by compensated cirrhosis with a Child-Turcotte-Pugh score <7 and HCC by radiological criteria or histology. Control subjects with compensated cirrhosis were frequency matched with cases by gender and disease aetiology. Overt manifestations of portal hypertension and previous therapy for liver disease or HCC were exclusion criteria. Region of interest analyses were performed on hepatic parenchyma regions distant to HCC location among cases. RESULTS Thirty patients with HCC and 60 matched controls comprised the study cohort. The mean age for cases was 64±10 years (range, 45-85) with 70% being men. Major disease aetiologies were chronic viral hepatitis (57%), non-alcoholic fatty liver disease (33%) and alcohol (10%). Twenty-eight (93%) patients had solitary HCC lesions with a mean size of 5.2 cm (range, 2-14 cm). However, patients with HCC had similar liver stiffness among uninvolved areas distant to HCC lesions, when compared with controls without HCC (mean, 6.1±2.0 vs. 6.3±2.5 kPa, P=0.7). CONCLUSION In contrast to previous studies with transient elastography, we did not observe a systematic association between liver stiffness assessed using MRE and the presence of HCC in patients with compensated cirrhosis.

Abstract
OBJECTIVE Case reports and short-term clinical trials have suggested that treatment for chronic hepatitis B (CHB) may lead to improvement of cirrhosis. The aim of the present study was to measure liver stiffness in patients diagnosed with advanced fibrosis or cirrhosis prior to prolonged treatment with nucleoside or nucleotide analogs (NUCs) for CHB. MATERIALS AND METHODS Patients with CHB and advanced fibrosis or cirrhosis prior to treatment with NUCs for at least 1 year were offered inclusion in the study. We measured liver stiffness using transient elastography (TE) at follow-up. TE cut-off levels to Metavir classification for fibrosis stage F2, F3 and F4 were ≥7.2 kPa, ≥8.1, and ≥11.0 kPa, respectively. RESULTS Among 66 patients with a successful TE examination at follow-up, 53 patients (80%) had cirrhosis and 13 had (20%) advanced fibrosis (F3) prior to treatment. Median treatment duration was 50.5 months. Among patients with cirrhosis prior to treatment, 26 (49%) had liver stiffness below 11.0 kPa at follow-up, suggesting regression of cirrhosis. Among patients with advanced fibrosis (F3) prior to treatment, 10 (77%) had liver stiffness below 8.1 kPa after treatment, suggesting improvement of fibrosis. CONCLUSION Transient elastography examinations demonstrate that prolonged treatment with NUCs in patients with CHB results in low liver stiffness, suggesting regression of fibrosis in a majority of patients with advanced fibrosis or cirrhosis.

Abstract
BACKGROUND AND AIMS Transient elastography (TE) is useful for predicting the fibrosis stage, but it is unsatisfactory as a substitute for liver biopsy, especially in patients with chronic hepatitis B (CHB). This study was performed to establish a reliable model for predicting significant fibrosis (SF) in patients with CHB. METHODS All CHB patients who were admitted to undergo liver biopsy were enrolled. They were randomly classified into either a training set (n = 139) or a validation set (n = 69). A model for predicting SF was established in the training set and validated in the validation set. Low and high cutoff values (COVs) were chosen for sensitivity ≥ 99% and specificity ≥ 99%, respectively. RESULTS A total of 208 patients were enrolled. Age was 39 ± 12 years and 149 (71.6%) were men. In the training set, liver stiffness values and serum haptoglobin, apolipoprotein A1, and α2-macroglobulin levels were independent predictors of SF on multivariate analysis. These variables were used to construct a novel model, called the HALF index. The area under the receiver operating characteristics curve of the HALF index for predicting SF was significantly higher than that of TE alone (0.915 vs 0.877, P = 0.010). Using low and high COVs of the HALF index, it appears that approximately half (47.1%) of patients could avoid liver biopsy, with an associated accuracy of 99.0%. CONCLUSION A combination of liver stiffness and serum markers identified SF with a high degree of accuracy. Approximately half of all patients with CHB could avoid liver biopsy through the utilization of the HALF index.

Abstract
AIM Transient elastography is a non-invasive tool to measure liver stiffness (LS), which has been reported to correlate with stage of liver fibrosis. Extrahepatic cholestasis was reported to cause elevated LS, which is considered to be attributed to the increased hydrostatic pressure in the liver. In the present study, the correlation of LS with laboratory data was investigated in extrahepatic cholestasis. The change of LS after biliary drainage was also assessed. METHODS LS was measured in 29 patients with extrahepatic cholestasis due to carcinomas in 12 and non-neoplastic diseases of biliary tract or pancreas in 17. RESULTS In 15 patients, LS was 11.4 kPa or higher which suggested liver cirrhosis in chronic infection of hepatitis C virus. LS significantly correlated positively with serum bilirubin levels (r = 0.726, P < 0.0001) and negatively with serum aspartate aminotransferase (AST) levels (r = -0.481, P = 0.0082) and alanine aminotransferase (ALT) levels (r = -0.631, P = 0.0002). Biliary drainage led to a reduction of bilirubin by 13.5 to 0.9 mg/dL which was significantly correlated with a reduction of LS by 14.3 to 0.5 kPa (r = 0.524, P = 0.0257). CONCLUSION In extrahepatic cholestasis, the elevation of LS which is probably attributed to the increased hydrostatic pressure in the liver, correlates positively with the accumulation of bilirubin but negatively with damage of hepatocytes indicated by ALT levels. Further studies on the mechanism underlying the elevation of LS should be helpful to elucidate the pathogenesis of extrahepatic cholestasis.
