Abstract
BACKGROUND Arterial stiffening may contribute to the pathogenesis of metabolic dysfunction-associated steatotic liver disease. We aimed to assess relations of vascular hemodynamic measures with measures of hepatic steatosis and fibrosis in the community. METHODS Our sample was drawn from the Framingham Offspring, New Offspring Spouse, Third Generation, Omni-1, and Omni-2 cohorts (N=3875; mean age, 56 years; 54% women). We used vibration-controlled transient elastography to assess controlled attenuation parameter and liver stiffness measurements as measures of liver steatosis and liver fibrosis, respectively. We assessed noninvasive vascular hemodynamics using arterial tonometry. We assessed cross-sectional relations of vascular hemodynamic measures with continuous and dichotomous measures of hepatic steatosis and fibrosis using multivariable linear and logistic regression. RESULTS In multivariable models adjusting for cardiometabolic risk factors, higher carotid-femoral pulse wave velocity (estimated β per SD, 0.05 [95% CI, 0.01-0.09]; P=0.003), but not forward pressure wave amplitude and central pulse pressure, was associated with more liver steatosis (higher controlled attenuation parameter). Additionally, higher carotid-femoral pulse wave velocity (β=0.11 [95% CI, 0.07-0.15]; P<0.001), forward pressure wave amplitude (β=0.05 [95% CI, 0.01-0.09]; P=0.01), and central pulse pressure (β=0.05 [95% CI, 0.01-0.09]; P=0.01) were associated with more hepatic fibrosis (higher liver stiffness measurement). Associations were more prominent among men and among participants with obesity, diabetes, and metabolic syndrome (interaction P values, <0.001-0.04). Higher carotid-femoral pulse wave velocity, but not forward pressure wave amplitude and central pulse pressure, was associated with higher odds of hepatic steatosis (odds ratio, 1.16 [95% CI, 1.02-1.31]; P=0.02) and fibrosis (odds ratio, 1.40 [95% CI, 1.19-1.64]; P<0.001). CONCLUSIONS Elevated aortic stiffness and pressure pulsatility may contribute to hepatic steatosis and fibrosis.

Health Sci Rep 2023; 6:e1184. [PMID: 37021011 PMCID: PMC10069238 DOI: 10.1002/hsr2.1184] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 01/26/2023] [Accepted: 02/16/2023] [Indexed: 04/05/2023] Open
Abstract
Background and Aims Transient elastography (TE) has largely replaced liver biopsy to evaluate fibrosis stage and cirrhosis in chronic hepatitis C. Previous studies have reported excellent reliability of TE but agreement metrics have not been reported. This study aimed to assess interrater agreement and reliability of repeated TE measurements. Methods Two operators performed TE independently, directly after each other. The primary outcome was disagreement, defined as a difference in TE results between operators of ≥33%, as well as the smallest detectable change, SDC95 (i.e., the difference between measurements needed to state with 95% certainty that there is a difference in underlying stiffness). Secondary outcomes included reliability, measured as intraclass correlation (ICC), and patient and examination characteristics associated with the agreement. Results In total, 65 patients were included, with a mean liver stiffness of 9.7 kPa. Of these, 21 (32%) had a disagreement in TE results of ≥33% between the two operators. The SDC95 on the log scale was 1.97, indicating that an almost twofold increase or decrease in liver stiffness would be required to confidently represent a change in the underlying fibrosis. Reliability, estimated using the ICC, was acceptable at 0.86. In a post hoc analysis, fasting less than 5 h before TE was associated with a higher degree of disagreement (48% vs. 19%, p = 0.03). Conclusions In our clinical setting, interrater agreement in directly repeated TE measurements was surprisingly low. It is essential to further investigate the reliability and agreement of TE to determine its validity and usefulness.

Abstract
Non-alcoholic fatty liver disease (NAFLD), and its progressive form, non-alcoholic steatohepatitis (NASH), represent, nowadays, real challenges for the healthcare system. Liver fibrosis is the most important prognostic factor for NAFLD, and advanced fibrosis is associated with higher liver-related mortality rates. Therefore, the key issues in NAFLD are the differentiation of NASH from simple steatosis and identification of advanced hepatic fibrosis. We critically reviewed the ultrasound (US) elastography techniques for the quantitative characterization of fibrosis, steatosis, and inflammation in NAFLD and NASH, with a specific focus on how to differentiate advanced fibrosis in adult patients. Vibration-controlled transient elastography (VCTE) is still the most utilized and validated elastography method for liver fibrosis assessment. The recently developed point shear wave elastography (pSWE) and two-dimensional shear wave elastography (2D-SWE) techniques that use multiparametric approaches could bring essential improvements to diagnosis and risk stratification.

Abstract
PURPOSE Liver elastography is increasingly being applied in screening for and follow-up of pediatric liver disease, and has been shown to correlate well with fibrosis staging through liver biopsy. Because time is of the essence when examining children, we wanted to evaluate if a reliable result can be achieved with fewer acquisitions. MATERIALS AND METHODS 243 healthy children aged 4-17 years were examined after three hours of fasting. Participants were divided into four age groups: 4-7 years; 8-11 years; 12-14 years and 15-17 years. Both two-dimensional shear wave elastography (2D-SWE; GE Logiq E9) and point shear wave elastography (pSWE; Samsung RS80A with Prestige) were performed in all participants, while transient elastography (TE, Fibroscan) was performed in a subset of 87 children aged 8-17 years. Median liver stiffness measurement (LSM) values of 3, 4, 5, 6, 7, and 8 acquisitions were compared with the median value of 10 acquisitions (reference standard). Comparison was performed for all participants together as well as within every specific age group. We investigated both the intraclass correlation coefficient (ICC) with absolute agreement and all outliers more than 10 %, 20 % or ≥ 0.5 or 1.0 kPa from the median of 10 acquisitions. RESULTS For all three systems there was no significant difference between three and ten acquisitions, with ICCs ≥ 0.97. All systems needed 4 acquisitions to achieve no LSM deviating ≥ 1.0 kPa of a median of ten. To achieve no LSM deviating ≥ 20 % of a median of ten acquisitions, pSWE and TE needed 4 acquisitions, while 2D-SWE required 6 acquisitions. CONCLUSION Our results contradict recommendations of 10 acquisitions for pSWE and TE and only 3 for 2D-SWE.

Flow Resistance Analysis of Clinically Significant Portal Hypertension in Patients with Liver Cirrhosis. Can J Gastroenterol Hepatol 2022; 2022:9396371. [PMID: 36199982 PMCID: PMC9529497 DOI: 10.1155/2022/9396371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 07/01/2022] [Accepted: 09/02/2022] [Indexed: 11/18/2022] Open
Abstract
Cirrhosis-induced clinically significant portal hypertension (CSPH) is a fatal disease. Early detection of CSPH is vitally important to reduce the patients' mortality rate. In this study, combined with three-dimensional image construction technology and computational fluid dynamics (CFD), an image-based flow resistance analysis was proposed. The flow resistance analysis was performed for nine cirrhosis patients with CSPH and ten participants without liver diseases, respectively. The results showed that the flow resistance coefficient of the portal vein system in CSPH patients was significantly lower than that in the control group (0.97 ± 0.11 Pa/(mL/s) for CSPH patients; 1.80 ± 0.40 Pa/(mL/s) for the control group; P = 0.028). In contrast, although main portal vein dilation was found in CSPH patients, the cross-sectional area enlargement was not statistically significant (186.01 ± 57.48 mm2 for CSPH patients; 166.26 ± 33.74 mm2 for the control group; P = 0.39). The research outcomes indicated that the flow resistance analysis was more sensitive than the commonly used vessel size measurement in the detection of CSPH. In summary, we suggest using flow resistance analysis as a supplementary noninvasive method to detect cirrhosis patients with CSPH.

Validation of Baveno VI and Expanded-Baveno VI Criteria for predicting gastroesophageal varices in patients with alcoholic and non-alcoholic fatty liver disease. Acta Gastroenterol Belg 2022; 85:321-329.

Abstract
Background and aims: Baveno VI and Expanded-Baveno VI Criteria were validated to rule out high-risk esophageal varices (HRV) and to prevent unneeded endoscopies in compensated advanced chronic liver disease (cACLD) mainly related to viral hepatitis. We aim to assess these criteria to rule out low- and high- risk varices in patients with cACLD secondary to alcoholic liver disease (ALD) and non- alcoholic fatty liver disease (NAFLD).
Methods: Data were collected retrospectively from 2016 to 2020. Inclusion criteria were: NAFLD and /or ALD related cACLD, a liver stiffness measurement (LSM) ≥ 10 kPa and an esophagogastroduodenoscopy (EGD) within 12 months. Exclusion criteria were: use of non cardioselective β-blockers, hepatic decompensation, previous variceal bleeding, portal thrombosis, liver cancer, or liver transplant.
Results: One hundred and ninety-four patients were included in this study. Eighty-one patients (42%) met Baveno VI criteria and 103 (53%) met Expanded-Baveno VI criteria. Baveno VI criteria yielded a high negative predictive value (NPV ≥ 95%) for detecting HRV and varices of any size. Expanded-Baveno VI criteria yielded a high NPV ≥ 95% only for detecting HRV: the miss rate for varices of any size was 8%. Expanded-Baveno VI criteria could avoid more endoscopies than the original Baveno VI criteria to rule out HRV (53% versus 42%).
Conclusion: In this study, both criteria showed high NPV to rule out HRV but only original Baveno VI criteria yielded a satisfactory high NPV to rule out varices of any size. Expanded-Baveno VI criteria could avoid more endoscopies to exclude HRV.

Abstract
PURPOSE The Liver Disease and Reproductive Ageing (LIVRA) study leverages the infrastructure of the decades-long multicentre prospective Women's Interagency HIV Study (WIHS) to examine the contributions of HIV, hepatitis C virus (HCV) and ageing to liver disease progression in women. PARTICIPANTS From 2013 to 2018, LIVRA enrolled 1576 participants (77 HCV-seropositive only, 248 HIV/HCV-seropositive, 868 HIV-seropositive only and 383 HIV/HCV-seronegative) who underwent vibration controlled transient elastography (VCTE). A VCTE quality assurance programme was established to ensure consistency and accuracy for longitudinal assessment of steatosis (fatty liver) via the controlled attenuation parameter (CAP) and fibrosis via liver stiffness (LS). Demographic, lifestyle factors, anthropometry, clinical and medication history, host genetics, immune markers and hormone levels were collected as part of the WIHS. FINDINGS TO DATE At baseline, 737 of 1543 women with CAP measurements had steatosis (CAP ≥248 dB/m) and 375 of 1576 women with LS measurements had significant fibrosis (LS ≥7.1 kPa), yielding a prevalence of 48% and 24%, respectively. On multivariable analysis, waist circumference (WC) and insulin resistance were independently associated with higher CAP (17.8 dB/m per 10 cm (95% CI:16.2 to 19.5) and 1.2 dB/m per doubling (95% CI:0.8 to 1.6), respectively). By contrast, HIV/HCV seropositivity and HCV seropositivity alone were associated with less steatosis compared with HIV/HCV-seronegative women, although the latter did not reach statistical significance (-9.2 dB/m (95% CI:-18.2 to -0.3) and -10.4 dB/m (95% CI: -23.8 to 3.1), respectively). Factors independently associated with higher LS were age (4.4% per 10 years (95% CI: 0.4% to 8.4%)), WC (5.0% per 10 cm (95% CI: 3.3% to 6.6%)), CAP steatosis (0.6% per 10 dB/m (95% CI: 0.1% to 1.0%)), HIV/HCV seropositivity (33% (95% CI: 24% to 44%)) and HCV seropositivity alone (43% (95% CI: 28% to 60%)). Excluding scans that were invalid based on traditional criteria for unreliability did not affect the results. FUTURE PLANS Enrolled women undergo VCTE at 3-year intervals unless LS is ≥9.5 kPa, indicating advanced fibrosis, in which case VCTE is performed annually. Participants also undergo VCTE every 6 months until 18 months after HCV treatment initiation. Analysis of the data collected will provide insights into the impact of ageing/ovarian function, host genetics, immune function and contemporary HIV and HCV treatments on liver disease progression.

Diagnostics (Basel) 2021; 11:diagnostics11101817. [PMID: 34679515 PMCID: PMC8535143 DOI: 10.3390/diagnostics11101817] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 09/24/2021] [Accepted: 09/27/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND The aim of this study was to evaluate the usefulness of two different types of 2-dimensional shear wave elastography (2D-SWE) for predicting liver fibrosis stages in comparison to transient elastography (TE), using a histologic METAVIR scoring system as the reference method. METHODS A total of 203 patients with chronic liver disease were prospectively enrolled in the study. Two different 2D-SWEs (LOGIQ S8 and E9 systems, GE Healthcare, Chalfont St Giles, UK) were assessed for liver stiffness in patients with chronic liver diseases. Patients received 2D-SWE examinations with the S8 and E9 systems, and also underwent TE (FibroScan®, Echosens, France) tests and liver biopsies on the same day. RESULTS The most common etiology of chronic liver disease was non-alcoholic fatty liver disease (28.7%), followed by chronic hepatitis B (25.1%). Liver fibrosis stages consisted of F0 (22.6%), F1 (29.7%), F2 (16.9%), F3 (12.8%) and F4 (17.9%). Overall, S8 and E9 were well correlated with the histologic fibrosis stages. The optimal cut-off values for S8 and E9 to differentiate significant fibrosis (≥F2) were 6.70 kPa and 6.42 kPa, respectively, while the cut-off values for S8 and E9 in distinguishing liver cirrhosis were 9.15 kPa and 8.88 kPa, respectively. Among the 195 patients who had successful measurements in both S8 and E9, liver stiffness showed good inter-equipment correlation (ICC: 0.900, p < 0.001). Regarding diagnostic ability, upon comparison (FibroScan®), there were no significant differences between 2D-SWEs and TE for detecting every stage of liver fibrosis. CONCLUSION In comparison to TE, 2D-SWE with LOGIQ S8 and E9 (GE Healthcare) are useful non-invasive tools for predicting significant fibrosis and liver cirrhosis.

Abstract
Yichang is a city in central China in the Hubei Province. This study aimed to estimate the dynamics of the transmissibility of hepatitis C using a mathematical model and predict the transmissibility of hepatitis C in 2030. Data of hepatitis C cases from 13 counties or districts (cities) in Yichang from 2008 to 2016 were collected. A susceptible-infectious-chronic-recovered (SICR) model was developed to fit the data. The transmissibility of hepatitis C at the counties or districts was calculated based on new infections (including infected or chronically infected cases) reported monthly in the city caused by one infectious individual (MNI). The trend of the MNI was fitted and predicted using 11 models, with the coefficient of determination (R2 ) was being used to test the goodness of fit of these models. A total of 3065 cases of hepatitis C were reported in Yichang from 2008 to 2016. The median MNI of Yichang was 0.0768. According to the fitting results and analysis, the trend of transmissibility of hepatitis C in Yichang City conforms with the logarithmic (R2 = 0.918, p < 0.001):MNI = 0.265-0.108 log(t) and exponential (R2 = 0.939, p < 0.001): MNI = 0.344e(-0.278t) models. Hence, the transmission of hepatitis C virus at the county level has a downward trend. In conclusion, the transmissibility of hepatitis C in Yichang has a downward trend. With the current preventive and control measures in place, the spread of hepatitis C can be controlled.

Abstract
Data on the presence of subclinical fibrosis across multiple organs in patients with idiopathic lung fibrosis (IPF) are lacking. Our study aimed at investigating through hepatic transient elastography (HTE) the prevalence and clinical impact of subclinical liver fibrosis in a cohort of patients with IPF. Patients referred to the Centre for Rare Lung Disease of the University Hospital of Modena (Italy) from March 2012 to February 2013 with established diagnosis of IPF and without a documented history of liver diseases were consecutively enrolled and underwent HTE. Based on hepatic stiffness status as assessed through METAVIR score patients were categorized as "with liver fibrosis" (corresponding to a METAVIR score of F1-F4) and "without liver fibrosis" (METAVIR F0). Potential predictors of liver fibrosis were investigated through logistic regression model among clinical and serological variables. The overall survival (OS) was assessed according to liver fibrosis and multivariate Cox regression analysis was used to identify independent predictors. In 13 out of 37 patients (35%) with IPF, a certain degree of liver fibrosis was documented. No correlation was found between liver stiffness and clinical-functional parameters. OS was lower in patients 'with liver fibrosis' than in patients 'without liver fibrosis' (median months 33 [23-55] vs. 63 [26-94], p = 0.038). Patients 'with liver fibrosis' presented a higher risk of death at seven years as compared to patients 'without liver fibrosis' (HR = 2.6, 95% CI [1.003-6.7], p = 0.049). Higher level of AST to platelet ratio index (APRI) was an independent predictor of survival (HR = 4.52 95% CI [1.3-15.6], p = 0.02). In our cohort, more than one-third of IPF patients had concomitant subclinical liver fibrosis that negatively affected OS. These preliminary claims further investigation aimed at clarifying the mechanisms beyond multiorgan fibrosis and its clinical implication in patients with IPF.

Abstract
The clinical outcomes differ between patients with cavernous transformation of the portal vein (CTPV) with and without cirrhosis. Therefore, invasive liver biopsy may be needed for the differential diagnosis of patients with CTPV with or without cirrhosis. The present study aimed to investigate the diagnostic efficacy of liver stiffness measurements (LSM) for the prediction of cirrhosis in patients with CTPV. A total of 20 patients with CTPV, 34 with chronic hepatitis B (CHB)-related cirrhosis and 20 healthy volunteers, were retrospectively recruited in the study. CTPV was diagnosed with contrast-enhanced computed tomography (CT) and ultrasound for the abdomen. LSM values were detected for each patient, while liver biopsy was performed in each patient in the CTPV and cirrhosis groups. The results demonstrated that LSM values were significantly lower in the CTPV group (12.5 kPa; range, 6.8-21.5 kPa) compared with the CHB-related cirrhosis group (21.0 kPa; range, 15.5-27.2 kPa; P=0.017). However, this was still higher compared with healthy volunteers (4.9 kPa; range 4.0-5.8 kPa; P<0.001). In addition, CTPV patients with cirrhosis (17.7 kPa; range, 13.9-30.8 kPa) exhibited significantly increased LSM values compared with those without cirrhosis (6.4 kPa; range, 5.7-7.8 kPa; P<0.001). Furthermore, LSM values in CTPV patients without cirrhosis were slightly higher compared with those of healthy volunteers (P=0.003), while no statistically significant difference was observed in LSM between CTPV patients with cirrhosis and CHB-related cirrhosis group. These findings indicated that LSM values could be used for the differential diagnosis of CTPV patients with or without cirrhosis. However, further validation studies are needed.

Abstract
BACKGROUND Severity of liver cirrhosis plays an important role in determining the safe extents of hepatectomy in patients with hepatocellular carcinoma (HCC). The aim of this study was to investigate whether direct liver stiffness measurement can help surgeons to evaluate the severity of liver cirrhosis in HCC patients. METHODS Overall, 119 HCC patients who underwent open hepatectomy were retrospectively studied. The severity of liver cirrhosis was histologically staged using the Laennec staging system. Direct liver stiffness measurement was performed during operation using a sclerometer device named LX-C Shaw hardmeter, and its efficacy in assessing the severity of liver cirrhosis was compared with that of transient elastography (TE) and cirrhotic severity scoring (CSS) previously proposed by our team. RESULTS Liver stiffness measured by LX-C Shaw hardmeter was significantly correlated with the severity of liver cirrhosis. Spearman correlation coefficients for the correlation between the severity of liver cirrhosis and direct liver stiffness measurement, TE, and CSS were 0.751, 0.454, and 0.705, respectively (all P < 0.001). The areas under the receiver operating characteristic curves (AUCs) of direct liver stiffness measurement were 0.891 for moderate cirrhosis and 0.944 for severe cirrhosis and superior to those of TE (0.735 and 0.776, respectively) and CSS (0.888 and 0.905, respectively). CONCLUSIONS Direct liver stiffness measurement is a useful method in evaluating the severity of liver cirrhosis in HCC patients.

Prognostic value of multiparametric magnetic resonance imaging, transient elastography and blood-based fibrosis markers in patients with chronic liver disease. Liver Int 2020; 40:3071-3082.

Abstract
BACKGROUND & AIMS Liver cT1 , liver T1 , transient elastography (TE) and blood-based biomarkers have independently been shown to predict clinical outcomes but have not been directly compared in a single cohort of patients. Our aim was to compare these tests' prognostic value in a cohort of patients with compensated chronic liver disease. METHODS Patients with unselected compensated liver disease aetiologies had baseline assessments and were followed up for development of clinical outcomes, blinded to the imaging results. The prognostic value of non-invasive liver tests at prespecified thresholds was assessed for a combined clinical endpoint comprising ascites, variceal bleeding, hepatic encephalopathy, hepatocellular carcinoma, liver transplantation and mortality. RESULTS One hundred and ninety-seven patients (61% male) with median age of 54 years were followed up for 693 patient-years (median (IQR) 43 (26-58) months). The main diagnoses were NAFLD (41%), viral hepatitis (VH, 25%) and alcohol-related liver disease (ArLD; 14%). During follow-up 14 new clinical events, and 11 deaths occurred. Clinical outcomes were predicted by liver cT1 > 825ms with HR 9.9 (95% CI: 1.29-76.4, P = .007), TE > 8kPa with HR 7.8 (95% CI: 0.97-62.3, P = .02) and FIB-4 > 1.45 with HR 4.09 (95% CI: 0.90-18.4, P = .05). In analysis taking into account technical failure and unreliability, liver cT1 > 825 ms could predict clinical outcomes (P = .03), but TE > 8kPa could not (P = .4). CONCLUSIONS We provide further evidence that liver cT1 , TE and serum-based biomarkers can predict clinical outcomes, but when taking into account technical failure/unreliability, TE cut-offs perform worse than those of cT1 and blood biomarkers.

Abstract
Evaluating liver steatosis and fibrosis is important for patients with non-alcoholic fatty liver disease. Although liver biopsy and pathological assessment is the gold standard for these conditions, this technique has several disadvantages. The evaluation of steatosis and fibrosis using ultrasound B-mode imaging is qualitative and subjective. The liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) determined using FibroScan are the evidence-based non-invasive measures of liver fibrosis and steatosis, respectively. The LSM and CAP measurements are carried out simultaneously, and the median values of more than ten valid measurements are used to quantify liver fibrosis and steatosis. Here, we demonstrate that the reliability of the LSM depends on the interquartile range to median ratio (IQR/Med), but CAP values do not depend on IQR/Med. In addition, the LSM is affected by inflammation, congestion, and cholestasis in addition to fibrosis, while CAP values are affected by the body mass index in addition to steatosis. We also show that the M probe provides higher LSM values but lower CAP values than the XL probe in the same population. However, there was no statistically significant difference between the diagnostic accuracies of the two probes. These findings are important to understand the reliability of FibroScan measurements and the factors influencing measurement values for all patients.

Abstract
BACKGROUND Untreated neonatal cholestasis can progress to liver cirrhosis and end stage liver disease in infancy due to prolonged hepatocyte and biliary tree injury and may require liver transplantation. Therefore, non-invasive evaluation of hepatic fibrosis is important in infants with cholestasis.
AIM To investigate the usefulness of periportal thickening (PT) measured on liver magnetic resonance imaging (MRI) for the assessment of hepatic fibrosis in infants with cholestasis including biliary atresia (BA).
METHODS This retrospective study included infants less than 6 mo who underwent liver MRI and biopsy for the evaluation of infantile cholestasis. PT and spleen size were measured on MRI. Serologic assessment was based on aspartate transaminase to platelet ratio index (APRI). The grade of histopathologic fibrosis was assessed by the METAVIR grading system. Correlation and diagnostic performance of PT, normalized spleen size ratio (SR, using the upper normal size limit), and APRI for diagnosing hepatic fibrosis were obtained by receiver-operating characteristic (ROC) curve analysis.
RESULTS A total of 155 patients were included, 110 of which were diagnosed with BA. Mean age at the time of MRI was 57.6 ± 34.4 d. There were positive correlations between fibrosis grade and PT and SR, even after adjusting age (all, P < 0.001). For the diagnosis of significant fibrosis (METAVIR grade F2-F4), the area under the ROC curve was 0.899 (95%CI: 0.840–0.941) for PT (cutoff, 4.2 mm), which was higher than 0.741 (95%CI: 0.664–0.808) for SR and 0.712 (95%CI: 0.634–0.782) for APRI (both, P < 0.001). For the diagnosis of cirrhosis (F4), the area under the ROC curve was the highest with SR as 0.790 (95%CI: 0.718–0.852).
CONCLUSION Liver MRI findings of PT and SR are useful to assess clinically significant hepatic fibrosis (F2 and higher) in infants with cholestasis including BA.

Abstract
Purpose This study investigated whether the use of ultrasound (US) guidance in transient elastography (TE) improved the technical success and reliability of liver stiffness (LS) measurements and whether 2-dimensional (2D) shear wave elastography (SWE) provided reliable LS measurements if TE measurements failed. Methods In this prospective study, 292 participants (male:female, 189:103; median age, 60 years) with chronic liver disease (CLD) were enrolled. LS was measured via the consecutive use of conventional TE, 2D-SWE, and US-guided TE. The technical success rates and reliable LS measurement rates of the three elastography techniques were compared. The risk factors for TE failure were assessed through univariate and multivariate logistic regression models. Results US-guided TE was associated with a higher technical success rate (281 of 292, 96.2%) and a higher reliable measurement rate (266 of 292, 91.1%) than conventional TE (technical success: 256 of 292, 87.7%; reliable measurements: 231 of 292, 79.1%; P<0.001 for both). In participants for whom conventional TE failed, 2D-SWE provided high rates of technical success (36 of 36, 100%) and reliable measurements (30 of 36, 83.3%). TE failure was associated with female sex (odds ratio [OR], 5.85; 95% confidence interval [CI], 1.30 to 26.40), severe reverberation artifacts (OR, 8.79; 95% CI, 3.93 to 19.69), and high skin-to-liver capsule depth (OR, 1.23; 95% CI, 1.09 to 1.39). Conclusion US guidance in TE improved the technical success and reliable measurement rates in the assessment of LS in patients with CLD. In participants for whom TE failed, subsequent 2D-SWE successfully delivered reliable LS measurements.

cows were used for this study. After the liver was located and subcutaneous tissue thickness was checked by means of ultrasonography, liver stiffness and CAP were measured using TE. At least
10 measurements were taken per individual cow. In addition, intraclass correlation coefficients were calculated for intra-rater and two-rater inter-rater reliability of liver stiffness and
CAP measurement, and were evaluated. Of the 85 cows, 61 (71.8%) were measurable owing to their significantly less body weight and subcutaneous tissue thickness compared with those of
unmeasurable cows. Liver stiffness showed no significant differences among sexes, ages, or breeds. CAP showed no significant differences among sexes and breeds. Intra- and inter-rater
reliabilities for liver stiffness and CAP were almost perfect. Both liver stiffness and CAP could be quantitatively evaluated with good reproducibility in cows using TE, and CAP increased
with the growth of the cows. However, evaluation was not possible in obese cows or cows with high values for subcutaneous tissue thickness or body weight.

Abstract
ABSTRACT Ultrasound elastography has become a promising noninvasive approach for assessing liver fibrosis. The purpose of this study was to evaluate the diagnosis ability of liver stiffness detected by shear wave elastography (SWE) for predicting the presence of esophageal varices (EVs) in cirrhotic patients. Four hundred sixty-eight cirrhotic patients were enrolled consecutively. Liver stiffness and EVs were detected by SWE and endoscopy, respectively. The baseline characteristics were recorded, and areas under the receiver operating characteristic curves (AUROCs) were used to compare the diagnosis accuracy. Multivariate analysis was used to identify the risk factors for EVs in cirrhosis. The mean liver stiffness was 18.4 kPa with a range of 6.8 to 52.5 kPa. Two hundred seventy-one patients had no EVs (57.9%), 139 patients had F1 EVs (29.7%), and 58 patients had high-risk EVs (12.4%). The optimal cutoff values of SWE for predicting EVs and high-risk varices were 18.5 and 20.4 kPa, respectively. The AUROCs for predicting the incidence of EVs were 0.792 (95% confidence interval [CI], 0.884-0.842), 0.814 (95% CI, 0.658-0.875), and 0.895 (95% CI, 0.813-0.918) for platelet, platelet count-to-spleen diameter ratio, and liver stiffness, respectively. For predicting the presence of high-risk varices, liver stiffness again had the highest AUROC. Multivariate analysis identified liver stiffness and platelet count-to-spleen diameter ratio as independent predictive factors for EVs in cirrhosis. Liver stiffness measured by SWE is an effective diagnostic tool for predicting EVs with greater accuracy, and SWE value is an independent factor for predicting high-risk EVs.

Abstract
The clinical value of the reliability measurement index (RMI), newly added to point shear wave elastography (pSWE), was investigated. Forty-nine patients underwent both pSWE providing RMI (range: 0.0-1.0) and transient elastography (TE) before hepatic surgery. Interclass correlation coefficients (ICCs) between the median of the first two to nine measurements (as categorized by RMI values ≥0.0 (liver stiffness-reliability measurement index [LS-RMI] 0.0), ≥0.4 (LS-RMI 0.4) and ≥0.7 (LS-RMI 0.7) and the median of 10 consecutive measurements (LS-REF) were obtained. Compared with LS-REF, minimums of 7 LS-RMI 0.0, 5 LS-RMI 0.4 and 3 LS-RMI 0.7 measurements were required to obtain an ICC ≥0.95 with high inter-observer agreement (ICC ≥0.90). Diagnostic performance did not differ (p values >0.05) using these reduced numbers of LS measurements. Significant correlations were found between the reduced number of LS measurements and TE or METAVIR (p values <0.001). Therefore, RMI helped to improve reliability and reduce the number of LS measurements while maintaining the diagnostic performance of pSWE.

Abstract
It has been postulated that in the liver, applying increased probe pressure during ultrasound-based shear wave elastography (SWE) might lead to a false increase in the SWE result. We aimed to determine the influence of increased intercostal probe pressure when performing SWE of the liver. We also investigated the number of measurements required to achieve technically successful and reliable SWE examinations. This prospective, clinical study included 112 patients and 2240 SWE measurements of the liver. We applied probe pressure intercostally, to reduce the skin-to-liver capsule distance (SCD), which could stabilize the SWE signal and thus increase the number of technically successful measurements. We performed 10 measurements with maximum probe pressure and 10 with normal pressure in each patient. Thus, two analysis groups were compared for differences. Compared with normal pressure, maximum probe pressure significantly reduced the SCD (p < 0.001) and significantly increased the number of technically successful measurements from 981 to 1098, respectively (p < 0.001). The SWE results with normal and maximum probe pressure were 5.96 kPa (interquartile range: 2.41) and 5.45 kPa (interquartile range: 1.96), respectively (p < 0.001). In obese patients, a large SCD poses a diagnostic challenge for ultrasound SWE. We found that maximum intercostal probe pressure could reduce the SCD and increase the number of technically successful measurements, without falsely increasing the SWE result. Only three measurements were required to achieve technically successful and reliable SWE examinations.

Abstract
Arrival time parametric imaging (At-PI) in contrast-enhanced ultrasonography is useful for assessing liver fibrosis in chronic hepatitis C (CHC) infection. The study aimed to elucidate the effect of hepatic inflammation on At-PI efficiency. Subjects were 159 CHC patients who underwent contrast-enhanced ultrasonography immediately before liver biopsy. Ultrasound contrast agent was injected, and contrast dynamics of the S5 to S6 region of the liver and right kidney were recorded for 40 seconds. The At-PI of liver parenchyma blood flow was generated using saved video clips. Hepatic blood flow during the first 5 seconds after starting contrast injection was displayed in red and that after another 5 seconds was displayed in yellow. The ratio of red (ROR) in At-PI images of the entire liver was measured with ImageJ. Ratio of red values of livers with different activity grades (0–3) were compared for each fibrosis (F) stage as determined by biopsy. Correlations of ROR with alanine aminotransferase (ALT) levels were analyzed using a linear regression line from the distribution map. Comparison of ROR for different activity grades in each F stage revealed no significant differences. Correlation coefficient R (P value) for ALT and ROR was R = −0.0094 (P = 0.43) at F0 to F1, R = −0.186 (P = 0.21) at F2, R = −0.233 (P = 0.27) at F3, and R = 0.041 (P = 0.89) at F4, with no significant correlation between ALT and ROR in any F stage. Hepatic inflammation in CHC infection does not affect At-PI diagnostic accuracy.

Abstract
The aim of the study was to investigate patient-related factors associated with either reliable or poorly reliable measurement results of ultrasound-based shear wave elastography (SWE) of the liver. A total of 188 patients were analyzed prospectively with binary logistic regression using the interquartile range/median as cutoff to define two groups based on reliable and poorly reliable SWE results. SWE results correlated significantly with liver biopsy. Factors associated with reliable SWE results (i.e., no negative impact on measurements) were age, sex, cirrhosis, antiviral and/or cardiovascular medication, smoking habits and body mass index. Factors associated with poorly reliable SWE results were increased skin-to-liver capsule distance (odds ratio = 3.08, 95% confidence interval: 1.70-5.60) and steatosis (odds ratio = 2.89, 95% confidence interval: 1.33-6.28). These findings indicate that the interquartile range/median as a quality parameter is useful in avoiding poorly reliable SWE results. How best to examine patients with increased skin-to-liver capsule distance is a matter of some controversy, as the incidences of obesity, diabetes and metabolic syndrome are increasing worldwide; however, our results indicate that reliable SWE results can be obtained in this group of patients by using ultrasound-based SWE.

Abstract
BACKGROUND Liver elastography have been reported in hepatocellular carcinoma (HCC) with higher values; however, it is unclear to identify morbimortality risk on liver transplantation waiting list. AIM To assess liver stiffness, ultrasound and clinical findings in cirrhotic patients with and without HCC on screening for liver transplant and compare the morbimortality risk with elastography and MELD score. METHOD Patients with cirrhosis and HCC on screening for liver transplant were enrolled with clinical, radiological and laboratory assessments, and transient elastography. RESULTS 103 patients were included (without HCC n=58 (66%); HCC n=45 (44%). The mean MELD score was 14.7±6.4, the portal hypertension present on 83.9% and the mean transient elastography value was 32.73±22.5 kPa. The median acoustic radiation force impulse value of liver parenchyma was 1.98 (0.65-3.2) m/s and 2.16 (0.59-2.8) m/s in HCC group. The HCC group was significantly associated with HCV infection (OR 26.84; p<0.0001), higher levels of serum alpha-fetoprotein (OR 5.51; p=0.015), clinical portal hypertension (OR 0.25; p=0.032) and similar MELD score (p=0.693). The area under the receiver operating characteristics (AUROC) showed sensitivity and specificity for serum alpha-fetoprotein (cutoff 9.1 ng/ml), transient elastography value (cutoff value 9 kPa), and acoustic radiation force impulse value (cutoff value 2.56 m/s) of 50% and 86%, 92% and 17% and 21% and 92%, respectively. The survival group had a mean transient elastography value of 31.65±22.2 kPa vs. 50.87±20.9 kPa (p=0.098) and higher MELD scores (p=0.035). CONCLUSION Elastography, ultrasound and clinical findings are important non-invasive tools for cirrhosis and HCC on screening for liver transplant. Higher values in liver elastography and MELD scores predict mortality.

Abstract
The correlation between improvement in longitudinal liver stiffness and fibrosis regression has not been properly evaluated during long-term antiviral therapy in chronic hepatitis B (CHB) patients. In this study, liver stiffness was serially performed by FibroScan® every 26 weeks in a prospective cohort of CHB patients receiving entecavir. Results were compared with liver biopsies at baseline and week 78. A total of 120 treatment-naïve CHB patients were analyzed, in which 54 (45%) patients had fibrosis regression at 78 weeks of antiviral therapy. Liver stiffness measurement presented as a rapid-to-slow decline pattern and decreased more significantly in patients with fibrosis regression than those without improvement in fibrosis at week 78 (- 46.4 vs. - 28.6%, P < 0.001). Multivariate analysis revealed that percentage decline of 52-week and 78-week liver stiffness from baseline was independent predictive factors for fibrosis regression (OR = 46.6, P < 0.001; OR = 17.8, P = 0.002, respectively). Moreover, percentage decline of 78-week liver stiffness was moderately predictive of fibrosis regression (AUROC = 0.694, P < 0.001), while the optimal cutoff values were different between non-cirrhosis and cirrhosis patients (38 vs. 45%). Fibrosis regression could be predicted with a high positive predictive value (96%) in non-cirrhosis patients and could be excluded with a high negative predictive value (94%) in cirrhosis patients. In conclusion, serial liver stiffness measurement could be applied for longitudinal monitoring of fibrosis status in CHB patients. Continuous decline of liver stiffness after effective antiviral treatment could partially reflect fibrosis regression at an optimal cutoff value.

Abstract
Background/Aims Liver biopsy has traditionally been used for determining the degree of fibrosis, however there are several limitations. Endoscopic ultrasound (EUS) real-time elastography (RTE) is a novel technology that uses image enhancement to display differences in tissue compressibility. We sought to assess whether liver fibrosis index (LFI) can distinguish normal, fatty, and cirrhotic liver tissue.
Methods A total of 50 patients undergoing EUS were prospectively enrolled. RTE of the liver was performed to synthesize the LFI in each patient. Univariate and multivariable analyses were performed. Chi-square and t-tests were performed for categorical and continuous variables, respectively. A p-value of <0.05 was considered significant.
Results Abdominal imaging prior to endoscopic evaluation suggested normal tissue, fatty liver, and cirrhosis in 26, 16, and 8 patients, respectively. Patients with cirrhosis had significantly increased mean LFI compared to the fatty liver (3.2 vs. 1.7, p<0.001) and normal (3.2 vs. 0.8, p<0.001) groups. The fatty liver group showed significantly increased LFI compared to the normal group (3.8 vs. 1.4, p<0.001). Multivariable regression analysis suggested that LFI was an independent predictor of group features (p<0.001).
Conclusions LFI computed from RTE images significantly correlates with abdominal imaging and can distinguish normal, fatty, and cirrhotic-appearing livers; therefore, LFI may play an important role in patients with chronic liver disease.

Abstract
AIM To measure the hepatic artery blood flow index (HBI) by first pass radionuclide method and to evaluate its feasibility in predicting the extent of liver fibrosis induced by Schistosoma japonicum.
METHODS Sixty-seven patients with liver fibrosis induced by Schistosoma japonicum were recruited. Fibrosis was assessed in liver biopsies using the METAVIR scoring system. The HBI was measured using the intravenously injected nuclear isotope technetium-99-methylene diphosphate. The area under the receiver operating characteristic curve (AUROC) was used as a measure of diagnostic performance.
RESULTS There was a positive correlation between the HBI and the stage of liver fibrosis (P < 0.01). The AUROC of the HBI as a predictor of significant fibrosis was 0.916 (P = 0.000); when the cut-off point was set at 32.77, HBI had a sensitivity of 87.5%, a specificity of 62.5%, a positive predictive value (PPV) of 70.0%, a negative predictive value (NPV) of 83.3%, and a 95% confidence interval (CI) of 0.844-0.987. Additionally, the AUROC for the HBI as a diagnostic tool for severe cirrhosis was 0.832 (P = 0.000); when the cut-off point was set at 40.70, HBI had a sensitivity of 96.3%, a specificity of 58.8%, a PPV of 70.0%, a NPV of 96.5%, and a 95%CI of 0.729-0.935.
CONCLUSION Altogether, our results showed that HBI is a novel diagnostic tool for the assessment of liver fibrosis induced by Schistosoma japonicum.

Abstract
BACKGROUND Several fibrosis-related factors influence liver stiffness measurements (LSM); however, these changes have not been investigated in the context of the various disease stages of chronic hepatitis B (CHB). AIM The aim of this study was to assess the correlations between fibrosis-related factors and LSM in different disease stages of CHB. PATIENTS AND METHODS Patients with mild CHB (n=305) and cirrhotic hepatitis B (cirrhotic HB) (n=137) were compared with determine the relationship between LSM and fibrosis-related factors including parameters of liver inflammation [aminotransferase (ALT), aspartate transaminase (AST), total bilirubin (Tbil)], albumin, globulin, peripheral blood cells (neutrophil granulocytes, red blood cells, platelets), abdominal ultrasound B-scan parameters including right liver thickness, portal vein inradium, diameter of spleen (DS), thickness of spleen (TS), and splenic vein inradium (SV). RESULTS In patients with mild CHB, LSM was correlated strongly with ALT (r=0.3534, P<0.0001), AST (r=0.3976, P<0.0001), and ALT+AST (r=0.3760, P<0.0001). LSM was correlated closely with Tbil (r=0.2237, P<0.0001), albumin (r=-0.3126, P<0.0001), albumin/globulin (r=-0.3086, P<0.0001), SV (r=0.3317, P<0.0001), DS (r=0.4157, P<0.0001), and spleen volume (DS×TS) (r=-0.4399, P<0.0001). Red blood cells were correlated negatively with LSM in both mild CHB and cirrhotic HB patients (r=-0.1981, P=0.0203; r=-0.1593, P=0.0053). LSM was not correlated with age, peripheral blood cell parameters, right liver thickness, portal vein inradium, or TS in mild CHB or cirrhosis HB patients. However, in patients with cirrhotic HB, LSM values were not correlated significantly with other fibrosis-related factors, except for Tbil (r=0.2272, P=0.0076). CONCLUSION Our findings suggest that the magnitude of these correlations differs significantly between mild CHB and cirrhotic HB patients.

Abstract
The incidence and prevalence of nonalcoholic fatty liver disease (NAFLD) are increasing and identification of people at risk of disease progression is extremely important. The current gold standard for diagnosing NAFLD/nonalcoholic steatohepatitis (NASH) is by liver biopsy, but it has several limitations. Noninvasive tests via biomarkers and transient elastography to assess NAFLD/NASH are being used in clinical practice. The most validated diagnostic panels include the NAFLD fibrosis score, FIB-4 (Fibrosis-4), and FibroMeter. Transient elastography is very useful in evaluating advanced fibrosis and cirrhosis.

Abstract
Schistosomiasis remains an important public health issue. The presence and extent of liver fibrosis are associated with disease progression and prognosis. The study is aimed at exploring the value of liver stiffness measurement (LSM) by transient elastography in assessing liver fibrosis in patients with advanced schistosomiasis japonica. Seventy-three patients were consecutively recruited for the purpose of this study. The correlation between noninvasive parameters and histological fibrosis stages was analyzed and an area under receiver operating characteristic curve (AUROC) was used to assess diagnostic efficacy. Our results demonstrated that there are significant differences between LSM values of patients with different stages of fibrosis (F1 vs. F2, F2 vs. F3 and F3 vs. F4, P<0.01). The AUROC values of LSM in detecting significant fibrosis (F≥2), advanced fibrosis (F≥3) and cirrhosis (F=4) were 0.96, 0.90, and 0.92 respectively. The optimal cut-off LSM values were 8.0kPa, 9.5kPa, and 18.0kPa for significant fibrosis, advanced fibrosis and cirrhosis. Based on differences between AUROC values, LSM was proven to be superior to several serum models in detecting advanced fibrosis and cirrhosis. In conclusion, our study demonstrates that LSM is a reliable parameter for assessing risk of liver fibrosis in patients with advanced schistosomiasis japonica.

Abstract
PURPOSE The aim of this study was to evaluate the effects of antiviral therapy on liver stiffness measurement (LSM). METHODS Two hundred HBV patients were enrolled from four hospital centers in southern Italy; median age was 50.7 (25-75) males were 68%; 171 patients underwent to liver biopsy and 200 patients had LSM at baseline and 189 at the end of follow-up. One hundred and forty-nine patients were treated with nucleos(t)ide analogs, while 51 patients were untreated. The cutoffs of the LSM, related to the fibrosis stages, were as follows: non-advanced fibrosis ≤ 8.1 kPa and advanced fibrosis ≥ 8.2 Kpa. RESULTS At baseline, the median value of LSM was 14.1 kPa for advanced fibrosis/cirrhosis and 6.9 kPa for non-advanced fibrosis. LSM was performed at 24 months from the start of therapy. The treated patients (68% received Entecavir and 32% Tenofovir) showed a decrease in liver stiffness measurement of 1.5 kPa (p < 0.001) in non-advanced fibrosis and of 6 kPa (p < 0.001) in advanced fibrosis/cirrhosis. In the patients not undergoing antiviral treatment, no statistically significant change of the LSM was observed (p = 0.26). A logistic binary regression model showed that the only independent factor associated with a significant change in the LSM was the liver stiffness value at baseline (odd ratio 2.855; 95% CI 1.456-5.788; (p = 0.007). CONCLUSION Long-term antiviral therapy induced a significant reduction of liver stiffness measurement and this result may be related to the reduction of liver fibrosis.

Abstract
AIM To analyze clinical significance of preoperative liver stiffness measurement (LSM) by FibroScan in postcurative resection hepatitis B virus (HBV) related hepatocellular carcinoma (HCC). PATIENTS & METHODS A total of 263 patients underwent preoperative LSM and curative operation for primary HBV-positive HCC were enrolled. The correlation between preoperative LSM and survival was analyzed. RESULTS All patients were stratified into two groups using the optimal cut-off value (13.2 kPa) of LSM using the receiver-operating characteristic. Patients with an LSM ≥13.2 kPa had poorer overall survival (median, 61.3 vs 48.2 months, hazard ratio: 0.15; p = 0.009) and recurrence-free survival (median, 60.4 vs 47.0 months; hazard ratio: 0.32; p = 0.011) than patients with an LSM <13.2 kPa and LSM also have been confirmed as independent predictor for survival for HCC. DISCUSSION This could potentially guide patient stratification and individualized treatment. CONCLUSION Preoperative LSM can be considered as an independent prognostic factor for HBV-positive HCC after curative resection.

Abstract
AIM Transient elastography (TE) is a non-invasive method for predicting liver fibrosis. However, there are limited data regarding the performance of TE in Japanese patients with non-alcoholic fatty liver disease (NAFLD). We aimed to evaluate the association between liver stiffness measurement (LSM) by TE and liver fibrosis stage, and define a cut-off value for predicting liver fibrosis. METHODS A total of 171 Japanese patients with biopsy-proven NAFLD underwent LSM using TE with FibroScan. The area under the receiver operating characteristic curve of LSM and other non-invasive markers of liver fibrosis were compared to determine the most accurate method of predicting liver fibrosis. RESULTS Liver stiffness measurement significantly correlated with fibrosis stage (P < 0.001). The areas under the receiver operating characteristic curve of LSM for fibrosis stage ≥1 and ≥3 was 0.85 and 0.91, respectively and were higher than those of the aspartate aminotransferase/alanine aminotransferase ratio, aspartate aminotransferase to platelet ratio index, fibrosis-4 index, and NAFLD fibrosis score. The best cut-off values of LSM fibrosis stage ≥1 and ≥3 were 7.2 kPa (sensitivity 78.5%, specificity 78.3%) and 10.0 kPa (sensitivity 89.5%, specificity 87.6%), respectively. The combination of LSM (≥10 kPa) and type IV collagen 7 s (≥6.0 ng/mL) had a specificity of 97.6% for advanced fibrosis. The LSM in patients with high alanine aminotransferase levels or high body mass index was associated with false positive results regarding advanced fibrosis. CONCLUSIONS In NAFLD patients, TE has excellent utility for the assessment of liver fibrosis, particularly for advanced stage cases. The cut-off value of LSM by TE for predicting liver fibrosis stage ≥3 is 10.0 kPa in Japanese NAFLD patients.

Abstract
BACKGROUND Hepatitis C virus is a worldwide problem. Noninvasive methods for liver fibrosis assessment as ultrasound-based approaches have emerged to replace liver biopsy. The aim of this study was to evaluate the diagnostic accuracy of real-time elastography (RTE) in the assessment of liver fibrosis in patients with chronic hepatitis C (CHC), compared with transient elastography and liver biopsy. METHODS RTE, FibroScan and liver biopsy were performed in 50 CHC patients. In addition, aspartate aminotransferase to platelet ratio index (APRI) and routine laboratory values were included in the analysis. RESULTS RTE was able to diagnose significant hepatic fibrosis (F ≥2) according to METAVIR scoring system at cut-off value of 2.49 with sensitivity 100%, specificity 66%, and area under the receiver-operating characteristics (AUROC) 0.8. FibroScan was able to predict significant fibrosis at cut-off value 7.5 KPa with sensitivity 88%, specificity 100%, and AUROC 0.94.APRI was able to predict significant hepatic fibrosis (F ≥2) with sensitivity 54%, specificity 80%, and AUROC 0.69. There was a significant positive correlation between the FibroScan score and RTE score (r=0.6, P=0.001). CONCLUSIONS Although FibroScan is superior in determining significant hepatic fibrosis, our data suggest that RTE may be a useful and promising noninvasive method for liver fibrosis assessment in CHC patients especially in cases with technical limitations for FibroScan.

Abstract
Objectives: The aim of this study was to determine the prevalence of liver fibrosis in patients with human immunodeficiency virus (HIV) monoinfection versus those with HIV hepatitis-B virus (HBV) co-infection as assessed with shear wave elastography (SWE) in a tertiary sub-Saharan Africa hospital. Materials and Methods: A total of 105 consecutive patients, 70 with HIV monoinfection and 35 with HIV-HBV co-infection, had liver elastography obtained using SWE to assess for the presence of liver fibrosis the cutoff of which was 5.6 kPa. Assessment of aspartate aminotransferase-to-platelet ratio index (APRI) score (a noninvasive serum biomarker of liver fibrosis) in these patients was also done. Results: The prevalence of liver fibrosis was significantly higher (P < 0.0001) in patients with HIV-HBV co-infection, 25.7%, compared to those with HIV monoinfection, 7.1%. APRI score was greater in patients with HIV-HBV co-infection than those with HIV monoinfection. HIV co-infection with HBV accelerates progression to liver fibrosis. Association of a low cluster of differentiation 4 (CD-4) count with advanced fibrosis supports earlier starting of antiretroviral therapy to prevent rapid progression of liver disease in HIV-positive patients. Conclusion: In view of the high prevalence of liver fibrosis in patients with HIV-HBV co-infection, regular monitoring of the disease progression is recommended.

Abstract
Liver fibrosis represents the repair mechanism in liver injury and is a feature of most chronic liver diseases. The degree of liver fibrosis in chronic viral hepatitis infections has major clinical implications and presence of advanced fibrosis or cirrhosis determines prognosis. Treatment initiation for viral hepatitis is indicated in most cases of advanced liver fibrosis and diagnosis of cirrhosis entails hepatology evaluation for specialized clinical care. Liver biopsy is an invasive technique and has been the standard of care of fibrosis assessment for years; however, it has several limitations and procedure related complications. Recently, several methods of noninvasive assessment of liver fibrosis have been developed which require either serologic testing or imaging of liver. Imaging based noninvasive techniques are reviewed here and their clinical use is described. Some of the imaging based tests are becoming widely available, and collectively they are shown to be superior to liver biopsy in important aspects. Clinical utilization of these methods requires understanding of performance and quality related parameters which can affect the results and provide wrong assessment of the extent of liver fibrosis. Familiarity with the strengths and weaknesses of each modality is needed to correctly interpret the results in appropriate clinical context.

Abstract
Unidimensional transient elastography (TE) is a noninvasive technique, which has been increasingly used in the assessment of diffuse liver diseases. This paper focuses on reviewing the existing data on the use of TE in the diagnosis of fibrosis and in monitoring disease progression in alcoholic liver disease, on the factors that may influence the result of fibrosis prediction, and last but not least, on its potential use in assessing the steatosis degree. Therefore, this field is far from being exhausted and deserves more attention. Further studies are required, on large groups of biopsied patients, in order to find answers to all the remaining questions in this field.

Abstract
The framework of incompressible nonlinear hyperelasticity and viscoelasticity is applied to the derivation of one-dimensional models of nonlinear wave propagation in fiber-reinforced elastic solids. Equivalence transformations are used to simplify the resulting wave equations and to reduce the number of parameters. Local conservation laws and global conserved quantities of the models are systematically computed and discussed, along with other related mathematical properties. Sample numerical solutions are presented. The models considered in the paper are appropriate for the mathematical description of certain aspects of the behavior of biological membranes and similar structures.

Performance of transient elastography assessing fibrosis of single hepatitis B virus infection: a systematic review and meta-analysis of a diagnostic test. Hepatol Int 2015; 9:558-66. [PMID: 26187292 DOI: 10.1007/s12072-015-9643-z] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2014] [Accepted: 06/01/2015] [Indexed: 12/29/2022]
Abstract
INTRODUCTION Transient elastography has good diagnostic accuracy for predicting fibrosis and cirrhosis related to hepatitis B virus. However, the enrolled subjects in some studies have also included chronic hepatitis B patients with chronic hepatitis C coinfection or other etiologies of liver diseases. This might under- or overestimate the role of transient elastography in chronic hepatitis B patients. METHODS A systematic review was conducted on records in PubMed, EMBASE and the Cochrane Library electronic databases until 31 December 2013. We systematically assessed the effectiveness and accuracy of transient elastography for predicting the fibrosis and cirrhosis of the single hepatitis B virus. The questionnaire for quality assessment of diagnostic accuracy studies was used. RESULTS In this meta-analysis, out of 257 articles evaluated for eligibility, 165 satisfied the predetermined inclusion criteria for meta-analysis. Eventually, our final data set for the meta-analysis contained 19 studies. The areas under the summary receiver-operating characteristic curve for transient elastography of significant fibrosis and cirrhosis were 0.8225 and 0.9108, respectively. The pooled diagnostic odds ratios for transient elastography of significant fibrosis and cirrhosis were 11.19 (95 % CI 6.63-18.89) and 26.87 (95 % CI 17.88-40.38), respectively. In Europe, the areas of significant fibrosis and cirrhosis were 0.803 and 0.905; those in Asia were 0.871 and 0.914, respectively. CONCLUSIONS Based on this meta-analysis we claim that liver stiffness measurement using transient elastography has good diagnostic accuracy for predicting single hepatitis B virus-related significant fibrosis and cirrhosis, especially in Asian populations.

Abstract
PURPOSE In chronic liver diseases, liver stiffness (LS) is increased, primarily because of liver fibrosis, but other factors, such as intrahepatic deposits, may also be involved. We hypothesized that intrahepatic copper accumulation occurring in Wilson's disease (WD) also leads to an increase in LS. The aim of this study was thus to investigate the changes in LS during treatment in pediatric patients with WD. METHODS Consecutive patients younger than 18 years old, whose WD was diagnosed between 2008 and 2013, were enrolled. All patients underwent testing for liver function and urinary copper excretion, and LS was measured on transient elastography at baseline and at 6- to 12-month intervals during specific therapy. RESULTS Nine patients were included in the analysis; only two were diagnosed with cirrhosis. The median LS decreased during treatment from 15.1 kPa (range, 5.1-66 kPa) at baseline to 10 kPa (4-16.1 kPa) at follow-up interval 1, and to 6.1 kPa (3.9-11.6 kPa) at follow-up interval 2 (p < 0.0001). In parallel, the differences in urinary copper excretion over the follow-up period were not statistically significant, although the decrease in LS correlated with the increase in urinary copper excretion (r = 0.6). CONCLUSIONS In pediatric patients with WD, LS is high at the time of diagnosis and decreases during specific treatment, in parallel with an increase in the urinary copper concentration.

Abstract
AIM: To define the normal range of liver stiffness (LS) values using transient elastography in living-related liver transplantation candidate donors with normal liver histology.
METHODS: LS was measured using Fibroscan in 50 (16 women, 34 men) healthy potential donors (mean age 28.4 ± 5.9 years) who were being evaluated for liver donation for their relatives at the National Liver Institute, Menoufeya University, Egypt. All potential donors had normal liver tests and were negative for hepatitis B or C virus infection. Abdominal ultrasounds showed normal findings. None of the subjects had diabetes, hypertension, renal impairment, heart disease, or body mass index > 30 kg/m2. All subjects had normal liver histology upon liver biopsy. They all donated the right lobe of their liver with successful outcomes.
RESULTS: The mean LS was 4.3 ± 1.2 kPa (range: 1.8-7.1 kPa). The 5th and 95th percentiles of normal LS were 2.6 kPa and 6.8 kPa, respectively, with a median of 4 kPa; the interquartile range was 0.6 ± 0.4. LS measurements were not significantly different between men and women (4.4 ± 1.1 kPa vs 3.9 ± 1.3 kPa) and did not correlate with age. However, stiffness values were significantly lower in subjects with a body mass index < 26 kg/m2 compared to those with an index ≥ 26 kg/m2 (4.0 ± 1.1 kPa vs 4.6 ± 1.2 kPa; P <0.05). There were no differences in hospital stay or postoperative bilirubin, albumin,alanine and aspartate transaminases, or creatinine levels (at discharge) between donors with livers stiffness ≤ 4 kPa and those with stiffness > 4 kPa.
CONCLUSION: Healthy donors with normal liver histology have a median LS of 4 kPa. Stiffness values are elevated relative to increase in body mass index.

Abstract
BACKGROUND Patients with chronic hepatitis C have an increased risk of diabetes mellitus but the type and risk of developing diabetes-related complications have not yet been evaluated. METHODS In order to compare the incidence of diabetic microangiopathy in patients with new onset diabetes without microangiopathy we recruited 54 hepatitis C virus (HCV)-positive and 119 HCV-negative patients from January 2005 to December 2006. All patients were followed-up every 6 months for liver and diabetic complications and incidence of cardiovascular diseases up to December 2012 when data were retrospectively analyzed. RESULTS The two cohorts were comparable at enrolment except for mean body mass index, obesity rate and family history of diabetes (p=0.007). After 7.2 years of follow-up, 13 HCV-positive (24.1%) and 37 HCV-negative patients (31%) showed at least one microangiopathic complication (p=0.34); 5 HCV-positive (9.3%) and 13 HCV-negative patients (10.8%) reported cardiovascular diseases (p=0.2); 14 HCV-positive (24.5%) compared to 0 HCV-negative patients developed liver-related complications (p=0.0003). One HCV-positive patient died due to liver cancer, 1 HCV-negative patient died from myocardial infarction (p=0.3). Increasing age (HR=1.04, 95% CI: 1.00-1.07, p=0.04) and smoking (HR=2.94, 95% CI: 1.06-8.17, p=0.04) were positively associated to diabetic complications. CONCLUSIONS Incidence of microangiopathy is not significantly different in diabetics with or without chronic hepatitis C.

Abstract
Since the introduction of Transient Elastography (TE) into Australia in 2008, non-invasive liver fibrosis assessments have integrated themselves into clinical hepatology. The Australian Liver Association (ALA) recognizes these technologies perform an important role in the assessment of chronic viral hepatitis B and C. However, in the setting of viral hepatitis and many other chronic liver diseases, there remains no consensus or guidelines regarding the performance, utility or reporting of TE. Accordingly, the ALA sought to produce an expert consensus statement for the use of TE in chronic viral hepatitis. The recommendations incorporated in this document are based upon a thorough literature review and draw on extensive clinical experience using TE. The initial draft was presented at Australian Gastroenterology Week (AGW) 2013. Through a collaborative process and expert external review a finalized document was presented at AGW 2014.

Non-invasive ménage à trois for the prediction of high-risk varices: stepwise algorithm using lok score, liver and spleen stiffness. Liver Int 2015; 35:317-25.

Abstract
BACKGROUND & AIMS Liver stiffness (LS), spleen stiffness (SS) and serum markers have been proposed to non-invasively assess portal hypertension or oesophageal varices (EV) in cirrhotic patients. We aimed to evaluate the performance of a stepwise algorithm that combines Lok score with LS and SS for diagnosing high-risk EV (HREV) and to compare it with other already-validated non-invasive methods. METHODS We performed a cross-sectional study including 136 consecutive compensated cirrhotic patients with various aetiologies, divided into training (90) and validation (46) set. Endoscopy was performed within 6 months from inclusion for EV screening. Spleen diameter was assessed by ultrasonography. LS and SS were measured using Fibroscan. Lok score, platelet count/spleen diameter ratio, LSM-spleen diameter to platelet ratio score and oesophageal varices risk score (EVRS) were calculated and their diagnostic accuracy for HREV was assessed. The algorithm classified patients as having/not-having HREV. Its performance was tested and compared in both groups. RESULTS In the training set, all variables could select patients with HREV with moderate accuracy, the best being LSPS (AUROC = 0.818; 0.93 sensitivity; 0.63 specificity). EVRS, however, was the only independent predictor of HREV (OR = 1.521; P = 0.032). The algorithm correctly classified 69 (76.66%) patients in the training set (P < 0.0001) and 36 (78.26%) in the validation one. In the validation group, the algorithm performed slightly better than LSPS and EVRS, showing 100% sensitivity and negative predicted value. CONCLUSION The stepwise algorithm combining Lok score, LS and SS could be used to select patients at low risk of having HREV and who may benefit from more distanced endoscopic evaluation.

Abstract
With widespread screening and increasingly effective treatments for patients with viral hepatitis as well as the increasing prevalence of nonalcoholic fatty liver disease, the population presenting to the care of gastroenterologists and hepatologists is certain to increase. Assessment of advanced liver disease is traditionally invasive and expensive. Vibration-controlled transient elastography, commonly delivered by the FibroScan device, is an option recently approved by the Food and Drug Administration for the noninvasive assessment of liver disease at the point of care. Herein, we review the promise and pitfalls of vibration-controlled transient elastography with the aim of providing clinicians with a framework to interpret its results and apply this technology to the changing needs of our patients.

Abstract
Background A combination treatment of interferon and ribavirin is the standard and the commonly used treatment for chronic hepatitis C (CHC). Developing noninvasive tests like serum indicators that can predict treatment outcome at an early stage of therapy is beneficial for individualized treatment and management of CHC. A glyco-indicator based on the glyco-alteration of serum α1-acid glycoprotein, LecT-Hepa, was discovered by glycomics technologies as a robust indicator of liver fibrosis. Here, we investigated the clinical utility of LecT-Hepa for evaluation of treatment outcome. Results Firstly, ninety-seven patients with CHC were used for comparison of LecT-Hepa in serum and plasma. We found no significant difference in the concentrations of LecT-Hepa in serum and plasma. And then, 213 serum specimens from 45 patients who received 48 weeks of treatment with interferon and ribavirin were followed up for 96 weeks, and were used for evaluation of the role of LecT-Hepa. We found that LecT-Hepa might reflect the change in fibrosis regression during the treatment process. Moreover, the change of LecT-Hepa at the first 12 weeks of treatment could already predict the antiviral treatment response, which was more superior to FIB-4 index and aspartate aminotransferase-to-platelet ratio index (APRI) in this study. Conclusions These results provide a new perspective that serum glycoprotein could be used as a joint diagnosis indicator for estimation treatment outcome of viral hepatitis at earlier stage of therapy.
