Abstract
Nonalcoholic Fatty Liver Disease (NAFLD) is the most common cause of chronic liver disease in the United States. The NAFLD subtype, nonalcoholic steatohepatitis, represents a progressive form of the disease that can lead to cirrhosis, portal hypertension, and hepatocellular carcinoma. NAFLD is a diagnosis of exclusion and is strongly related to obesity and the metabolic syndrome. Although there has been an explosion of exciting therapeutic avenues for NAFLD in recent years, the bedrock of management continues to be lifestyle modification, weight loss, and optimization of metabolic risk factors.

Abstract
INTRODUCTION Despite the widespread use of transient elastography for non-invasive assessment of liver fibrosis, the optimal cut-off liver stiffness measurement (LSM) values remain unclear. This study aimed to validate the optimal cut-off LSM values for significant fibrosis and cirrhosis in patients with chronic liver disease (CLD). METHODS Prospective multicentre data of CLD patients who underwent paired liver biopsy and LSM was analysed to determine the optimal cut-off LSM values for predicting significant fibrosis (METAVIR F ≥ 2) and cirrhosis (METAVIR F4). A high-quality cohort was selected by excluding those with failed LSM and invalid LSM readings. RESULTS Of the 481 patients recruited, 322 fulfilled the pre-defined quality criteria. CLD aetiology was chronic hepatitis B (CHB) in 49%, non-alcoholic steatohepatitis (NASH) in 16% and chronic hepatitis C (CHC) in 12%. Area under the receiver operating characteristic curve for LSM was 0.775 (95% confidence interval [CI] 0.724-0.826) for significant fibrosis and 0.810 (95% CI 0.738-0.882) for cirrhosis. Optimal cut-off LSM values were 9 kPa for significant fibrosis and 13 kPa for cirrhosis in the general cohort. Optimal cut-off LSM values were 9 kPa for significant fibrosis and 12 kPa for cirrhosis for both CHB and CHC, while the corresponding values for NASH were 11 kPa and 15 kPa. CONCLUSION Optimal cut-off LSM values should be selected based on disease aetiology. In Singapore, the optimal cut-off LSM values for CHB and CHC are 9 kPa for significant fibrosis and 12 kPa for cirrhosis. Optimal cut-off values for NASH require further validation.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis in the absence of significant alcohol consumption (<40 g/week). The essential metabolic trait is insulin resistance, which is why NAFLD is associated with obesity, diabetes mellitus (DM), hyperlipidemia. Approximately one-quarter of adults with NAFLD present nonalcoholic steatohepatitis (NASH) leading to progressive hepatic fibrosis and finally cirrhosis and hepatocellular carcinoma. If liver biopsy (LB) has traditionally been NAFLD’s gold standard, over the past 15 years, its use has undergone an important transformation. In this review, the role of noninvasive tests (serological markers, imaging techniques) in the NAFLD evaluation is analyzed, starting from the low adherence of patients for LB, the complications of the technique, and the increased cost. LB is the only investigation that distinguishes between simple steatosis and NASH. However, in the medical practice, LB has gained lesser value; it is worth mentioning that NASH represents a small proportion compared to NAFLD. For this reason, most patients only show biopsy steatosis, which has a good prognosis. In addition, judging by the appearance of inflammation markers and fibrosis in the diagnosis technique, the use of LB has become increasingly rare in the definition of NASH.

Abstract
BACKGROUND The prevalence of non-alcoholic fatty liver disease (NAFLD) has increased. Non-alcoholic steatohepatitis (NASH) shows progression of liver fibrosis in NAFLD. It remains unclear which patients with NAFLD will show progression of liver fibrosis. Therefore, we aimed to investigate the risk factor associated with the progression of liver fibrosis among patients with NAFLD. METHODS This observational study enrolled 157 patients with biopsy-proven NAFLD. Thirty-two patients were excluded because of lack of data. The accuracy of the formulae for estimating liver fibrosis, i.e., the FIB-4 index, APRI, and Forns index, was compared. Using serial changes of the best formula for liver fibrosis, we identified factors associated with the progression of liver fibrosis. Histological liver fibrosis was quantified using the Brunt stage. RESULTS Sixty-three patients were diagnosed as having NASH. The FIB-4 index provided the best diagnostic accuracy for liver fibrosis [Brunt stage 0 versus 1-4, areas under the curve (AUC) 0.74; 0-1 versus 2-4, AUC 0.77; 0-2 versus 3-4, AUC 0.78; and 1-3 versus 4, AUC 0.87]. The association between body mass index, sex, observation period, and histological findings (liver fat content, bridging fibrosis, and hepatocyte ballooning) with the change in the FIB-4 index was evaluated among patients with NASH, using multivariate analysis. Among these factors, hepatocyte ballooning was associated with an increase in the FIB-4 index. CONCLUSION The FIB-4 index was the best formula for estimating liver fibrosis in patients with biopsy-proven NAFLD, and the presence of ballooned hepatocytes was a risk factor for the progression of liver fibrosis.

Abstract
Aim The purpose of this study was to create and validate a novel serological diagnostic index to predict cirrhosis of all etiologies. Methods This was a retrospective observational study of 771 patients, age >18 years, who underwent a liver biopsy. The stage of fibrosis and routine laboratory values were recorded. The data were randomly separated into 2 datasets (training 50% and testing 50%). A stepwise logistic regression model was used to develop the novel index. The area under the curve of receiver operating characteristic (AUROC) was applied to compare the new index to existing ones (Fibro-Q, FIB4, APRI, AAR), which was also validated in the testing dataset. Results Variables associated with the presence of cirrhosis were first assessed by univariate analysis then by multivariable analysis, which indicated serum glutamic-oxaloacetic acid transaminase, serum glutamic-pyruvic transaminase, international normalized ratio, albumin, blood urea nitrogen, glucose, platelet count, total protein, age, and race were the independent predictors of cirrhosis (P<0.05). Regression formula for prediction of cirrhosis was generated and a novel index was subsequently created. The diagnostic performance of the novel index for predicting cirrhosis was assessed using the receiver operating characteristic curve. The new index had significantly higher AUROC (0.83, 95% CI: 0.79–0.87) than Fibro-Q (0.80, 95% CI: 0.76–0.85), FIB4 (0.79, 95% CI: 0.74–0.83), APRI (0.74, 95% CI: 0.69–0.78), and AAR (0.72, 95% CI: 0.67–0.78). Conclusion The novel index had the highest AUROC curve when compared with current indices and can be applied to all etiologies of chronic liver disease.

Abstract
The aims of this article are to investigate the effects of Th22 and Th17 cells and plasma cytokines in patients with nonalcoholic fatty liver disease (NAFLD) and to examine the correlation between Th22 and Th17 cells levels and disease progression. Blood samples from 70 patients with NAFLD and 26 healthy controls (HCs) were collected. Flow cytometry and enzyme-linked immunosorbent assay (ELISA) analysis were performed. ELISA revealed interleukin (IL)-22 plasma level in FibroScan subgroup patients was 2.2-fold higher than that in the HCs ( P < 0.01), body mass index (BMI) subgroup patients were 2.3-fold higher than HCs ( P < 0.01), IL-17A plasma level was 5.6-fold higher in FibroScan subgroup patients than that in the HCs ( P < 0.01), and 5.8-fold higher in BMI subgroup than HCs ( P < 0.01). Flow cytometry revealed median proportions of Th22 cells in FibroScan group was greater than that in the HCs (3.85% vs 0.86%; P < 0.001). Similar results were obtained for Th17 cells (6.36% vs 0.9%; P < 0.001). The liver stiffness measurement value was highly correlated with the proportion of Th17 and Th22 cells and moderately correlated with the plasma level of IL-17A, IL-22, and the BMI value. In conclusion, the elevated proportions of Th17 and Th22 cells were significantly correlated with the degree of liver cirrhosis in NAFLD patients. They may play an inflammatory and immune response role in progression from nonalcoholic fatty liver (NAFL) to nonalcoholic steatohepatitis (NASH) or fibrosis.

Abstract
AIMS To describe the prevalence of significant liver fibrosis by ultrasound-based vibration-controlled transient elastography (VCTE; FibroScan®) and to identify the determinants of significant liver fibrosis in Thai chronic hepatitis B patients. METHODS A cross-sectional study of consecutive chronic hepatitis B patients performed VCTE and followed up at Rajavithi Hospital, Bangkok, Thailand, was conducted between 1 January, 2013, and 31 December, 2016. Liver fibrosis was defined as minimal (METAVIR F0-1) by VCTE < 7.2 kPa and significant (METAVIR F2-4) by VCTE ≥ 7.2 kPa. VCTE assessments and medical records were retrospectively reviewed. The prevalence and determinants of significant liver fibrosis were analyzed. RESULTS A total of 206 eligible patients were included; 120 patients (58.3%) were female. The mean age was 50 years (SD 12.4 years), and 32.5% had a body mass index ≥ 25. The prevalences of minimal (F 0-1) and significant fibrosis (F2-4) were 74.3% and 25.7%, respectively. The prevalence of hepatitis B e antigen negative (HBeAg -ve) was 83%. The median serum hepatitis B virus viral load was 4,340 IU/mL (range 20-271,883,036). Significant determinants of significant fibrosis (F2-4) were male gender (aOR 3.24 [95%CI: 1.36-7.72]) and high aspartate transaminase (AST) level (aOR 5.71 [95%CI: 2.03-16.04]). CONCLUSION Around one-quarter of the Thai patients with chronic viral hepatitis B had significant liver disease defined by VCTE, requiring further evaluation for specific treatment for hepatitis B virus. Determinants of significant liver fibrosis were male gender and high AST level.

Abstract
Background and aims Many patients with liver disease come to medical attention once they have advanced cirrhosis or acute decompensation. Most often, patients are screened for liver disease via liver function tests (LFTs). There is very limited published data evaluating laboratory values with biopsy-proven stages of hepatic fibrosis. We set out to evaluate whether any correlation exists between routine LFTs and stages of hepatic fibrosis. Methods A large retrospective observational study on 771 liver biopsies was conducted for evaluating the stage of fibrosis with AST, ALT, INR, BUN, creatinine, platelets, alkaline phosphatase, bilirubin, and albumin. Mean and 95% confidence intervals were used to describe the distributions of serum markers in different fibrosis stages. Multivariable generalized linear models were used and a two-tailed P-value was calculated. Results ALT was not statistically significant for any stage, and AST was statistically significant for stage 3 and 4 fibrosis. INR was statistically significant only in stage 4 disease but remained near the upper limit of normal range. Albumin failed to show a clinically relevant association. Platelets remained within normal laboratory range for all stages. The remaining laboratory values failed to show statistical and clinical significance. Conclusion The health care burden from chronic liver disease (CLD) will likely continue to rise, unless clinicians are made aware that normal or near normal laboratory findings may be seen in asymptomatic patients. Earlier identification of asymptomatic patients will allow for treatment with new promising modalities and decrease morbidity and mortality from CLD. Our study shows that laboratory values correlate poorly with liver disease.

Abstract
Substance users have the highest prevalence of hepatitis C virus (HCV) infection but have rarely been treated, largely because of their mistrust of the health care system, misconceptions about the consequences of the infection, and concerns regarding interferon-related side effects. With the development of highly efficacious, interferon-free therapeutic regimens without significant side effects, the concept of colocating HCV and substance use treatment would appear to be highly feasible. This process has been further facilitated by widespread clinical adaptation of noninvasive assays for fibrosis assessment, which could be performed routinely in substance use treatment facilities. The most commonly used noninvasive fibrosis assessment methods are serum marker indexes and transient elastography, both of which are very accurate in detecting cirrhosis or the absence of fibrosis, but much less successful in identifying intermediate fibrosis stages. The effect of drugs of abuse on the liver is not completely understood or sufficiently studied. There are no indications that heroin and cocaine affect fibrosis progression, but some recreational drugs (eg, alcohol and cannabis) can induce hepatic injury. In addition, knowledge gaps exist on the effect of impaired liver function on metabolism or transport of agents used to treat substance disorders as well as their interactions with HCV antivirals.

Abstract
The hepatitis C virus (HCV) is the most common blood-borne infection in the United States and is the most common cause of end-stage liver disease requiring liver transplant. Over the last 10 years, direct acting antiviral therapies have revolutionized HCV treatment, increasing the cure rates from less than 50% to more than 90% in those who reach access to care. This article is an overview for pathologists and clinicians covering the histologic findings of HCV as well as direct acting antiviral therapy.

Abstract
Chronic hepatitis C (CHC) is a leading cause of hepatic fibrosis and cirrhosis. The level of fibrosis is traditionally established by histology, and prognosis is estimated using fibrosis progression rates (FPRs; annual probability of progressing across histological stages). However, newer noninvasive alternatives are quickly replacing biopsy. One alternative, transient elastography (TE), quantifies fibrosis by measuring liver stiffness (LSM). Given these developments, the purpose of this study was (i) to estimate prognosis in treatment-naïve CHC patients using TE-based liver stiffness progression rates (LSPR) as an alternative to FPRs and (ii) to compare consistency between LSPRs and FPRs. A systematic literature search was performed using multiple databases (January 1990 to February 2016). LSPRs were calculated using either a direct method (given the difference in serial LSMs and time elapsed) or an indirect method given a single LSM and the estimated duration of infection and pooled using random-effects meta-analyses. For validation purposes, FPRs were also estimated. Heterogeneity was explored by random-effects meta-regression. Twenty-seven studies reporting on 39 groups of patients (N = 5874) were identified with 35 groups allowing for indirect and 8 for direct estimation of LSPR. The majority (~58%) of patients were HIV/HCV-coinfected. The estimated time-to-cirrhosis based on TE vs biopsy was 39 and 38 years, respectively. In univariate meta-regressions, male sex and HIV were positively and age at assessment, negatively associated with LSPRs. Noninvasive prognosis of HCV is consistent with FPRs in predicting time-to-cirrhosis, but more longitudinal studies of liver stiffness are needed to obtain refined estimates.

Abstract
NAFLD is a global epidemic. The prevalence of NAFLD is 20-30% in North America, northern Europe, Australia, Japan, India and China. It is crucial that patients with NAFLD receive an assessment for their risk of advanced fibrosis, which increases the risk of hepatocellular carcinoma and other complications of cirrhosis. Risk stratification that is efficient, cost-effective, patient-centred and evidence-based is one of the most important issues facing clinicians who care for those with liver disease. Given patients' preference to avoid liver biopsy, noninvasive alternatives to assess liver fibrosis are in high demand. The most accurate noninvasive methods are based on liver elastography. Research on these techniques - which include vibration-controlled transient elastography (VCTE), magnetic resonance elastography (MRE), shear-wave elastography and acoustic radiation force impulse - has proliferated. Unfortunately, the literature has not kept pace with clinical practice. There is limited guidance for how clinicians should anticipate and manage the pitfalls of these tests. Furthermore, guidance is unavailable for clinicians regarding the optimal incorporation of VCTE, MRE or the emerging elastographic techniques into their clinical strategy, particularly for patients with NAFLD. In this Review, we summarize the available evidence, highlight gaps to address in further research and explore optimization of these techniques in clinical practice.

Direct Acting Agents (DAAs) have high cure rate but still lack the knowledge of their effect on hepatic steatosis in chronic hepatitis C (CHC). Controlled Attenuation Parameter (CAP), evaluated with transient elastography, could help in assessment of steatosis grades. We aim to evaluate the effect of DAAs on BMI and steatosis in CHC using CAP. This cohort study included 155 CHC Egyptian patients divided into three groups according to the DAAs regimens. All patients were subjected to pre-treatment and 3-months post-treatment evaluation including BMI, laboratory workup and liver stiffness measurement with simultaneous CAP determination using the (FibroScan®) M probe. Patients mean age was 45.78 ± 11.6 years, 60.6% were females, mean BMI 26.63 ± 2.75 and 18.1% were cirrhotic. Baseline assessment revealed no steatosis in 43.9%, 32.9% had mild-moderate steatosis and 23.2% had severe steatosis. The overall sustained virological response 12 was 93.6%. Follow-up revealed stationary steatosis in 56.7% of patients and regression in 21.3%. Mean pre-treatment CAP were significantly lower in responders 244.9 ± 62.4 dB/m versus non-responders; 300 ±28.4 dB/m (P = 0.04). ROC curve delineated 273 dB/m as best cutoff for detection of responders with an AUC of 0.801, sensitivity 68.2%, and specificity 100%. BMI significantly increased after treatment (P = 0.004) particularly in patients with worsened steatosis (P = 0.001). Steatosis significantly correlated with BMI (r = 0.3, P value = < 0.001). DAAs causes a significant change in steatosis grade in a subset of treated patients. Pretreatment CAP was significantly lower in responders. BMI significantly increases following treatment particularly in patients with worsened steatosis.

Direct-Acting Antiviral Therapy for Chronic HCV Infection Results in Liver Stiffness Regression Over 12 Months Post-treatment. Dig Dis Sci 2018; 63:486-492. [PMID: 28887750 DOI: 10.1007/s10620-017-4749-x] [Citation(s) in RCA: 49] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2017] [Accepted: 08/31/2017] [Indexed: 02/08/2023]
Abstract
BACKGROUND Liver fibrosis stage determines risk of morbidity and mortality from chronic hepatitis C virus (HCV) infection. Prior data have shown long-term reversal of liver fibrosis, measured by vibration-controlled transient elastography (VCTE), in patients successfully treated with interferon-based therapies. AIM Our study sought to determine the effect of treatment with modern HCV direct-acting antiviral (DAA) therapy on noninvasive liver fibrosis measurements. METHODS A total of 70 patients had VCTE-based liver stiffness measurement (LSM) taken before treatment, directly after treatment completion, and at least 12 months after completion of DAA therapy. Our primary outcome was a >30% improvement in VCTE score at the end of follow-up, relative to baseline. RESULTS The sustained virologic response rate in our cohort was 95.7%. In our cohort, 34 (48.6%) met the primary outcome. Those who had baseline elevated alanine aminotransferase (OR 3.27; 95% CI 1.13-9.47) and genotype 1 (OR 14.63; 95% CI 1.70-125.83) had higher odds of meeting that outcome, and this remained significant after adjusting for age, baseline body mass index, gender, baseline elevated alkaline phosphatase levels, treatment experience, liver transplant status, smoking, and baseline liver stiffness. CONCLUSION Treatment of chronic HCV with modern DAA therapy was associated with a significant improvement in LSM by VCTE measurement, suggesting possible early improvement in liver fibrosis along with resolution of inflammation over the first year after treatment completion.

Abstract
Vibration-controlled transient elastography estimates liver stiffness measurement (LSM) and controlled attenuation parameter (CAP), which are noninvasive assessments of hepatic fibrosis and steatosis, respectively. However, prior vibration-controlled transient elastography studies reported high failure rates in patients with nonalcoholic fatty liver disease. We examined the performance characteristics of the FibroScan 502 Touch with two probes, medium (M+) and extra large (XL+), in patients with nonalcoholic fatty liver disease in a multicenter setting. A total of 1,696 exams were attempted in 992 patients (body mass index, 33.6 ± 6.5 kg/m2 ) with histologically confirmed nonalcoholic fatty liver disease. Simultaneous assessment of LSM and CAP was performed using the FibroScan 502 Touch with an automatic probe selection tool. Testing was conducted twice in patients by either a single operator (87%) or two operators (13%). Failure was defined as the inability to obtain a valid examination. An examination was considered unreliable if LSM interquartile range/median was >30%. Significant disagreement between two readings was defined as >95% limits of agreement between two readings. A total of 1,641 examinations yielded valid results with a failure rate of 3.2% (55/1,696). The proportion of unreliable scans for LSM was 3.9%. The proportion of unreliable scans with operator experience in the top quartile (≥59 procedures) was significantly lower than that in the lower three quarters combined (1.6% versus 4.7%, P = 0.02 by Fisher's exact test). The significant disagreement between first and second readings for LSM and CAP when obtained back to back was 18% and 11%, respectively. CONCLUSION Vibration-controlled transient elastography for estimation of LSM and CAP can be successfully deployed in a multicenter setting with low failure (3.2%) and high reliability (>95%) rates and high reproducibility.

Abstract
Accurate staging of liver fibrosis is important for clinical decision making and personalized management. Liver fibrosis is influenced by patients' genomics, including IFNL3 genotype and microRNA expression. However, incorporating microRNAs into fibrosis prediction algorithms has not been investigated. We examined the potential of eight selected serum microRNAs; miR-122, miR-126, miR-129, miR-199a, miR-155, miR-203a, miR-221, and miR-223 as non-invasive biomarkers to stage liver fibrosis in HCV-associated chronic liver disease (HCV-CLD). 145 Egyptian HCV-CLD patients were divided according to Metavir fibrosis scores. MicroRNAs and IFNL3 rs12979860 genotype were assayed by RT-qPCR and allelic discrimination techniques, respectively. Serum miR-122 was downregulated, whereas miR-203a and miR-223 were upregulated in significant fibrosis (≥F2) compared with no/mild fibrosis (F0-F1). Serum miR-126, miR-129, miR-203a, and miR-223 were upregulated in severe fibrosis (≥F3) and cirrhosis (F4) compared with F0-F2 and F0-F3, respectively. miR-221 was upregulated in ≥F3, but unchanged in F4. miR-155, miR-199a, and IFNL3 rs12979860 genotype were not significantly different in all comparisons. Differentially expressed serum microRNAs discriminated ≥F2, ≥F3, and F4 by receiver-operating-characteristic analysis. Multivariate logistic analysis revealed a model combining miR-129, miR-223, AST, and platelet count with high diagnostic accuracy for ≥F3 (AUC=0.91). The model also discriminated F4 (AUC=0.96) and ≥F2 (AUC=0.783), and was superior to APRI and FIB-4 in discriminating ≥F3 and F4, but not ≥F2. In conclusion, combining serum microRNAs with baseline predictors could serve as a new non-invasive algorithm for staging HCV-associated liver fibrosis. Additional studies are required to confirm this model and test its significance in liver fibrosis of other etiologies.

Nonalcoholic fatty liver with a hepatic arterial buffer response strongly associated with future metabolic disease. Hepatol Commun 2017; 1:623-633. [PMID: 29404482 PMCID: PMC5721441 DOI: 10.1002/hep4.1070] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2017] [Revised: 04/23/2017] [Accepted: 06/26/2017] [Indexed: 12/22/2022] Open
Abstract
A change in hepatic blood flow caused by the hepatic arterial buffer response (HABR) occurs as fatty liver disease progress. The aim of this longitudinal cohort study was to investigate whether fatty liver with the HABR induces metabolic disorders. In 2009 and 2010, 494 (89.5%) participants were enrolled. The median follow‐up duration was 5.0 (interquartile range, 3.9‐6.0) years. The hazard ratios of fatty liver with the HABR for incident metabolic disorders were assessed by Cox proportional hazard models. A non–fatty liver group (non‐FL group, hepatorenal echo intensity ratio <1.12), a fatty liver without portal hypertension (FL group, hepatorenal echo intensity ratio ≥1.12 and ratio of the maximal blood velocity in the right hepatic artery to maximal blood velocity in the right portal vein <3.1) group, and a fatty liver with portal hypertension (FL‐HABR group, hepatorenal echo intensity ratio ≥1.12 and ratio of the maximal blood velocity in the right hepatic artery to maximal blood velocity in the right portal vein ≥3.1) group were defined based on echo intensity and Doppler ultrasonography. Fatty liver with and without the HABR was significantly associated with the incidence of diabetes on multivariate analysis (non‐FL versus FL group, hazard ratio, 3.36; 95% confidence interval, 1.05‐12.85; FL versus FL with the HABR group, HR, 2.68; 95% confidence interval, 1.28‐6.04). With respect to the incidence of hypertension and dyslipidemia, only FL with the HABR was a significant factor (hypertension, non‐FL versus FL, P = 0.874, FL versus FL‐HABR, P = 0.016, non‐FL versus FL‐HABR, P = 0.023; dyslipidemia, non‐FL versus FL, P = 0.311, FL versus FL‐HABR, P = 0.194, non‐FL versus FL‐HABR, P = 0.038). Conclusion: Fatty liver with the HABR is a high‐risk condition for metabolic diseases. (Hepatology Communications 2017;1:623–633)

BMC Gastroenterol 2017; 17:62.

Abstract
BACKGROUND Mac-2 Binding Protein Glycosylation isomer (M2BPGi) is a novel serological glyco-biomarker for staging liver fibrosis. Here, we aimed to evaluate the efficiency of serum M2BPGi in identifying liver fibrosis stages in Chinese patients with chronic hepatitis C infection. METHODS Serum M2BPGi levels were evaluated in 680 patients with chronic hepatitis C and 164 healthy controls who underwent the Fibro Scan® test of liver fibrosis. The diagnostic accuracy of serum M2BPGi values was compared to that of other fibrosis markers, including Fibro Scan®, the aspartate transaminase to platelet ratio index (APRI), the fibrosis index based on four factors (FIB4), and the gamma-glutamyltranspeptidase to platelet ratio (GPR). RESULTS Among the chronic hepatitis C patients, the median serum M2BPGi level increased with increasing fibrosis score as follows: 0.88 (≤F2), 1.70 (F2/F3), and 5.68 (cirrhosis). M2BPGi concentrations could also distinguish between healthy controls (0.38 ± 0.24) and hepatitis C patients (1.57 ± 2.28). After adjusting for potential confounders, M2BPGi was the most significant factor associated with the liver stiffness measurement (effect size = 0.275, P < 0.001). The optimum cutoff values of serum M2BPGi for patients with F2 and F4 were 0.945 and 1.355, respectively. The area under the curve of serum M2BPGi for prediction of significant fibrosis (F ≥ 4) using was comparable to that of APRI (0.892 vs. 0.873), while it was superior to that of other alternative markers, including FIB4 (0.818) and GPR (0.851). Compared with other non-invasive markers, M2BPGi had the greatest specificity for diagnosing cirrhosis and cirrhosis in hepatitis C patients. CONCLUSIONS Our results suggest that the level of serum M2BPGi would be a simple and reliable diagnostic tool for identifying liver fibrosis stage in Chinese patients with chronic hepatitis.

Abstract
Chronic liver diseases (CLDs), due to chronic hepatitis C; hepatitis B; nonalcoholic fatty liver diseases (NAFLD); and alcoholic liver disease, are a leading cause of morbidity and mortality globally. Early identification of patients with cirrhosis at high risk of progression to liver-related complications may facilitate timely care and improve outcomes. With risks and misclassification associated with invasive tests, such as liver biopsy, noninvasive imaging modalities for liver fibrosis assessment have gained popularity. Therefore, the American Gastroenterological Association prioritized clinical guidelines on the role of elastography in CLDs, focusing on vibration-controlled transient elastography (VCTE) and magnetic resonance elastography (MRE). To inform these clinical guidelines, the current technical review was developed in accordance with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework for diagnostic accuracy studies. This technical review addresses focused questions related to: (1) comparative diagnostic performance of VCTE and MRE relative to nonproprietary, serum-based fibrosis markers for detection of cirrhosis in patients with hepatitis C virus (HCV), hepatitis B virus (HBV), NAFLD, and alcoholic liver diseases; (2) performance of specific VCTE-defined liver stiffness cutoffs as a test replacement strategy (to replace liver biopsy) in making key decisions in the management of patients with CLDs; and (3) performance of specific VCTE-defined liver stiffness cutoffs as a triage test to identify patients with low likelihood of harboring high-risk esophageal varices (EVs) or having clinically significant portal hypertension (for presurgical risk stratification). This technical review does not address performance of other noninvasive modalities for assessing fibrosis (eg, acoustic radiation force pulse imaging or shear wave elastography) or steatosis (controlled attenuation parameter or magnetic resonance imaging-estimated proton density fat fraction).

Abstract
AIM Superb microvascular imaging (SMI) is an ultrasound Doppler technique using a unique algorithm that allows visualization of minute vessels with slow velocity and minimal motion artifacts. The aim of this preliminary study was to investigate whether SMI could predict liver fibrosis by visualizing the vessels present in the vicinity of the liver surface because the morphology of the peripheral hepatic vasculature is affected by the progression of liver fibrosis. METHODS We recruited 29 patients with biopsy-proven chronic hepatitis C or liver cirrhosis C, and 36 patients without liver disease as controls. Using an Aplio 500 ultrasound system with a 7-MHz or 12-MHz linear probe, we assessed the vascular shapes and the bifurcation angles of five randomly selected vessels in the vicinity of the liver surface. The vascular shape was scored based on the number of winding and/or irregular vessels. RESULTS The mean vascular score and the mean bifurcation angle were significantly greater in patients with advanced liver fibrosis (3.5 ± 1.1 and 90.5 ± 14.3) than in those with mild-to-moderate liver fibrosis (1.3 ± 1.4 and 68.0 ± 16.1) and controls (0.6 ± 0.7 and 62.2 ± 10.5). The area under the receiver-operating curve of the vascular score and the bifurcation angle were 0.88 with 76.5% sensitivity and 83.3% specificity, and 0.87 with 94.1% sensitivity and 75.0% specificity, respectively. CONCLUSION The present results indicate that SMI potentially predicts the extent of liver fibrosis by detecting small vessels present in the vicinity of the liver surface.

Abstract
Early data regarding the "real-world" experience with novel therapies for hepatitis C (HCV) are encouraging. Data are still limited, however, regarding real-world rates of sustained virologic response (SVR) for ledipasvir-sofosbuvir (LDV-SOF), particularly for patients with prior treatment failure. We performed a retrospective cohort study of 1597 patients with chronic genotype 1 HCV who were treated using 12 weeks of the following regimens LDV-SOF±ribavirin (RBV) (n=1521 without RBV, n=76 with RBV). The primary outcome was SVR-determined at 12 weeks in an intention-to-treat design. Prescription according to Food and Drug Administration (FDA) approved labelling (adding RBV for patients with cirrhosis and treatment failure) was assessed in multivariate models. The study population was aged 60 years on average (range 19-89), 60% male, 50% Caucasian, 43% cared for at an academic centre and 30% cirrhotic. Overall, LDV-SOF resulted in a 94% SVR rate. Only 44 (2.9%) patients relapsed. LDV-SOF+RBV yielded SVR in 97% with 0 viral relapses. While cirrhosis and thrombocytopenia were associated with lower odds of SVR, in a multivariable regression model, only treatment at an academic centre and prescriptions contrary to FDA labelling were significantly associated with lower SVR-odds ratios, 0.56 95% CI (0.35-0.87) and 0.29 95% CI(0.12-0.68), respectively. The real-world experience with LDV-SOF mirrors the SVR rates observed in clinical trials. Efforts to promote prescription within FDA recommendations are warranted.

Abstract
Directly acting antiviral (DAA) combination therapies for chronic hepatitis C virus (HCV) infection are highly effective, but treatment decisions remain complex. Laboratory testing is important to evaluate a range of viral, host, and pharmacological factors when considering HCV treatment, and patients must be monitored during and after therapy for safety and to assess the viral response. In this review, we discuss the laboratory tests relevant for the treatment of HCV infection in the era of DAA therapy, grouped according to viral and host factors.

Abstract
Clinicians are required to assess abnormal liver chemistries on a daily basis. The most common liver chemistries ordered are serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase and bilirubin. These tests should be termed liver chemistries or liver tests. Hepatocellular injury is defined as disproportionate elevation of AST and ALT levels compared with alkaline phosphatase levels. Cholestatic injury is defined as disproportionate elevation of alkaline phosphatase level as compared with AST and ALT levels. The majority of bilirubin circulates as unconjugated bilirubin and an elevated conjugated bilirubin implies hepatocellular disease or cholestasis. Multiple studies have demonstrated that the presence of an elevated ALT has been associated with increased liver-related mortality. A true healthy normal ALT level ranges from 29 to 33 IU/l for males, 19 to 25 IU/l for females and levels above this should be assessed. The degree of elevation of ALT and or AST in the clinical setting helps guide the evaluation. The evaluation of hepatocellular injury includes testing for viral hepatitis A, B, and C, assessment for nonalcoholic fatty liver disease and alcoholic liver disease, screening for hereditary hemochromatosis, autoimmune hepatitis, Wilson's disease, and alpha-1 antitrypsin deficiency. In addition, a history of prescribed and over-the-counter medicines should be sought. For the evaluation of an alkaline phosphatase elevation determined to be of hepatic origin, testing for primary biliary cholangitis and primary sclerosing cholangitis should be undertaken. Total bilirubin elevation can occur in either cholestatic or hepatocellular diseases. Elevated total serum bilirubin levels should be fractionated to direct and indirect bilirubin fractions and an elevated serum conjugated bilirubin implies hepatocellular disease or biliary obstruction in most settings. A liver biopsy may be considered when serologic testing and imaging fails to elucidate a diagnosis, to stage a condition, or when multiple diagnoses are possible.

Abstract
BACKGROUND Liver transplanted patients need close surveillance for early signs of graft disease. OBJECTIVES Transient elastography can safely be repeated over time, offering serial liver stiffness measurement values. Serial stiffness measurements were compared to single baseline stiffness measurements in predicting the appearance of liver-related clinical events and guiding subsequent clinical decisions. METHODS One hundred and sixty liver transplanted patients were observed for three years in our real-life practice. RESULTS Liver stiffness measurements were stable in 75% of patients, decreased in 4% of patients, and increased in 21% of patients. The pattern of increased stiffness measurements was associated with both HCV-RNA positive status and the presence of an active biliary complication of liver transplantation and was more predictive of a clinically significant event resulting from any disease of the transplanted liver when compared to a stable pattern or to a single liver stiffness measurement. The procedures that were consequently performed were often diagnostic for unexpected situations, both in HCV-RNA positive and HCV-RNA negative patients. CONCLUSIONS The pattern of longitudinally increased liver stiffness measurements efficiently supported clinical decisions for individualized management strategies. Repeated transient elastography in real-life clinical practice appears to have a practical role in monitoring liver transplanted patients.

Abstract
Hepatic fibrosis develops or progresses in 25 % of patients with autoimmune hepatitis despite corticosteroid therapy. Current management regimens lack reliable noninvasive methods to assess changes in hepatic fibrosis and interventions that disrupt fibrotic pathways. The goals of this review are to indicate promising noninvasive methods to monitor hepatic fibrosis in autoimmune hepatitis and identify anti-fibrotic interventions that warrant evaluation. Laboratory methods can differentiate cirrhosis from non-cirrhosis, but their accuracy in distinguishing changes in histological stage is uncertain. Radiological methods include transient elastography, acoustic radiation force impulse imaging, and magnetic resonance elastography. Methods based on ultrasonography are comparable in detecting advanced fibrosis and cirrhosis, but their performances may be compromised by hepatic inflammation and obesity. Magnetic resonance elastography has excellent performance parameters for all histological stages in diverse liver diseases, is uninfluenced by inflammatory activity or body habitus, has been superior to other radiological methods in nonalcoholic fatty liver disease, and may emerge as the preferred instrument to evaluate fibrosis in autoimmune hepatitis. Promising anti-fibrotic interventions are site- and organelle-specific agents, especially inhibitors of nicotinamide adenine dinucleotide phosphate oxidases, transforming growth factor beta, inducible nitric oxide synthase, lysyl oxidases, and C-C chemokine receptors types 2 and 5. Autoimmune hepatitis has a pro-fibrotic propensity, and noninvasive radiological methods, especially magnetic resonance elastography, and site- and organelle-specific interventions, especially selective antioxidants and inhibitors of collagen cross-linkage, may emerge to strengthen current management strategies.

Prediction for Improvement of Liver Function after Balloon-Occluded Retrograde Transvenous Obliteration for Gastric Varices to Manage Portosystemic Shunt Syndrome. J Vasc Interv Radiol 2016; 27:1160-7. [PMID: 27234486 DOI: 10.1016/j.jvir.2016.03.031] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2015] [Revised: 03/12/2016] [Accepted: 03/15/2016] [Indexed: 12/18/2022] Open
Abstract
PURPOSE To investigate predictive factors and cutoff value of transient elastography (TE) measurements for assessing improvement in liver function after balloon-occluded retrograde transvenous obliteration (BRTO) for gastric varices (GV). MATERIALS AND METHODS Retrospective analysis was performed of 50 consecutive patients followed for > 3 months after BRTO, who had undergone TE before BRTO between January 2011 and February 2015. The correlation between change in liver function (total bilirubin, albumin, and prothrombin time) and baseline liver function values and liver stiffness measurement (LSM) by TE was evaluated by Pearson correlation test. Receiver operating characteristic curves were used to determine cutoff values for discriminating between patients who had improved liver function and patients who did not. The time interval from BRTO to aggravation of esophageal varices (EV) (worsening morphology, development of new varices, or variceal rupture) grouped by cutoff values was also analyzed. RESULTS Serum albumin was significantly improved at 3 months after BRTO (3.57 g/dL vs 3.74 g/dL, P < .001). There was a significant negative correlation between change in albumin and baseline LSM (r = -0.50, P < .001). The best cutoff point for LSM was ≤ 22.9 kPa, with sensitivity and specificity of 78.4% and 69.2%, respectively, for predicting which patients would have improved albumin after BRTO. Among 33 patients, 29 (88%) patients had improved albumin. The 1-year progression rate of EV after BRTO was 13.6% in patients with LSM ≤ 22.9 kPa. CONCLUSIONS The predictive factor for improvement in albumin after BRTO was lower LSM (≤ 22.9 kPa) using TE.

The Performance of Vibration Controlled Transient Elastography in a US Cohort of Patients With Nonalcoholic Fatty Liver Disease. Am J Gastroenterol 2016; 111:677-84.

Abstract
OBJECTIVES Identification of patients with nonalcoholic fatty liver disease (NAFLD) who have advanced fibrosis is crucial. Vibration controlled transient elastography (VCTE) is an alternative to biopsy, although published experience with VCTE in a US population is limited. METHODS We performed a prospective cohort of 164 biopsy-proven NAFLD patients evaluated with VCTE using an M probe and the NAFLD fibrosis score (NFS) at baseline and a repeat VCTE at 6 months. Reliable liver stiffness measurements (LSMs) were defined as 10 valid measurements and interquartile range ≤30% of the median. RESULTS A total of 120 (73.2%) patients had reliable LSM. The median LSMs for patients with and without F3-F4 (advanced) fibrosis were 6.6 kPA (5.3-8.9) and 14.4 kPA (12.1-24.3), respectively. The optimal LSM cutoff for advanced fibrosis was 9.9 kPA (sensitivity 95% and specificity 77%). In addition, 100% of patients with LSM<7.9 kPA did not have advanced fibrosis. A risk stratification strategy based on VCTE avoids the need for biopsy in at least the 74 (45.1%) patients correctly classified as low risk for advanced fibrosis. For the detection of F3-F4 fibrosis in patients with reliable VCTE, the area under the receiver operating curve (AUROC) is 0.93 (95% CI: 0.86-0.96). This is superior to the AUROC for the NFS (0.77), P=0.01. Patients who achieved a ≥5% weight loss at 6-month follow-up experienced improved LSM (P=0.009), independent of the changes in aminotransferase levels. CONCLUSIONS Reliable VCTE results can rule out advanced fibrosis and avoid the need for biopsy in at least 45% of US patients with NAFLD. However, 1 in 4 patients have uninterpretable studies using the M probe.

Abstract
BACKGROUND & AIMS In non-alcoholic fatty liver disease, presence of fibrosis is predictive of long-term liver-related complications. Currently, there are no reliable and non-invasive means of quantifying fibrosis in those with non-alcoholic fatty liver disease. Therefore, we aimed to evaluate the performance of a panel of non-invasive models in predicting fibrosis in non-alcoholic fatty liver disease. METHODS The accuracy of FibroMeter non-alcoholic fatty liver disease, fibrosis 4 and four other non-invasive models in predicting fibrosis in those with biopsy proven non-alcoholic fatty liver disease was compared. These models were constructed post hoc in patients who had necessary clinical information collected within 2 months of a liver biopsy. The areas under receiver operating characteristics curves were compared for each model using Delong analysis. Optimum cut-off for each model and fibrosis stage were calculated using the Youden index. RESULTS The area under receiver operating characteristics curves for F ≥ 1 fibrosis for fibrosis 4 and FibroMeter non-alcoholic fatty liver disease was 0.821 and 0.801 respectively. For F ≥ 3, the area under receiver operating characteristics curves was 0.866 for fibrosis 4 and 0.862 for FibroMeter non-alcoholic fatty liver disease. Delong analysis showed the area under receiver operating characteristics curves was statistically different for fibrosis 4 and FibroMeter non-alcoholic fatty liver disease compared with BARD, BAAT and aspartate aminotransferase:alanine aminotransferase ratio for F ≥ 1 and F ≥ 3. Area under receiver operating characteristics curves were significantly different for fibrosis 4 and FibroMeter non-alcoholic fatty liver disease for F ≥ 3 compared with non-alcoholic fatty liver disease fibrosis score. At a fixed sensitivity of 90%, FibroMeter non-alcoholic fatty liver disease had the highest specificity for F ≥ 1 (52.4%) and F ≥ 3 (63.8%). In contrast, at a fixed specificity of 90%, fibrosis 4 outperformed other models with a sensitivity of 60.2% for F ≥ 1 and 70.6% for F ≥ 3 fibrosis. CONCLUSION These non-invasive models of fibrosis can predict varying degrees of fibrosis from routinely collected clinical information in non-alcoholic fatty liver disease.

Abstract
Background The complications of Nonalcoholic Fatty Liver Disease (NAFLD) are dependent on the presence of advanced fibrosis. Given the high prevalence of NAFLD in the US, the optimal evaluation of NAFLD likely involves triage by a primary care physician (PCP) with advanced disease managed by gastroenterologists. Methods We compared the cost-effectiveness of fibrosis risk-assessment strategies in a cohort of 10,000 simulated American patients with NAFLD performed in either PCP or referral clinics using a decision analytical microsimulation state-transition model. The strategies included use of vibration-controlled transient elastography (VCTE), the NAFLD fibrosis score (NFS), combination testing with NFS and VCTE, and liver biopsy (usual care by a specialist only). NFS and VCTE performance was obtained from a prospective cohort of 164 patients with NAFLD. Outcomes included cost per quality adjusted life year (QALY) and correct classification of fibrosis. Results Risk-stratification by the PCP using the NFS alone costs $5,985 per QALY while usual care costs $7,229/QALY. In the microsimulation, at a willingness-to-pay threshold of $100,000, the NFS alone in PCP clinic was the most cost-effective strategy in 94.2% of samples, followed by combination NFS/VCTE in the PCP clinic (5.6%) and usual care in 0.2%. The NFS based strategies yield the best biopsy-correct classification ratios (3.5) while the NFS/VCTE and usual care strategies yield more correct-classifications of advanced fibrosis at the cost of 3 and 37 additional biopsies per classification. Conclusion Risk-stratification of patients with NAFLD primary care clinic is a cost-effective strategy that should be formally explored in clinical practice.

Abstract
Transient elastography (TE) is a reliable tool for the non-invasive assessment of liver fibrosis in routine clinical practice. TE is currently approved for use in Europe, Asia and the United States. The widespread adoption of this technology is certain to increase the use of TE worldwide. Although TE has been well validated in chronic viral hepatitis, its clinical role in other liver diseases remains less clear. The advent of new treatment for chronic hepatitis C and emerging prevalence of non-alcoholic steatohepatitis raises new questions on the role of TE in current clinical practice. This review aims to examine the clinical applications, limitations and future role of TE in current clinical practice in light of the changing epidemiology of liver diseases and new clinical management paradigms. In current clinical practice, TE is the most accurate non-invasive method for diagnosis of liver cirrhosis. TE is useful to rule out fibrosis and cirrhosis but does not have sufficient accuracy to discern between various stages of fibrosis. The clinical role of TE has evolved from cross-sectional point-in-time assessment of fibrosis and cirrhosis to the more relevant role of prediction of vital clinical end-points. This provides clinicians with the ability to modify treatment strategies based on the information provided by TE. TE has evolved over the past decade to become an essential tool to assist the clinician in the management of chronic liver disease.

Abstract
BACKGROUND & AIMS The extent of liver fibrosis predicts long-term outcomes, and hence impacts management and therapy. We developed a non-invasive algorithm to stage fibrosis using non-parametric, machine learning methods designed for predictive modeling, and incorporated an invariant genetic marker of liver fibrosis risk. METHODS Of 4277 patients with chronic liver disease, 1992 with chronic hepatitis C (derivation cohort) were analyzed to develop the model, and subsequently validated in an independent cohort of 1242 patients. The model was assessed in cohorts with chronic hepatitis B (CHB) (n=555) and non-alcoholic fatty liver disease (NAFLD) (n=488). Model performance was compared to FIB-4 and APRI, and also to the NAFLD fibrosis score (NFS) and Forns' index, in those with NAFLD. RESULTS Significant fibrosis (⩾F2) was similar in the derivation (48.4%) and validation (47.4%) cohorts. The FibroGENE-DT yielded the area under the receiver operating characteristic curve (AUROCs) of 0.87, 0.85 and 0.804 for the prediction of fast fibrosis progression, cirrhosis and significant fibrosis risk, respectively, with comparable results in the validation cohort. The model performed well in NAFLD and CHB with AUROCs of 0.791, and 0.726, respectively. The negative predictive value to exclude cirrhosis was>0.96 in all three liver diseases. The AUROC of the FibroGENE-DT performed better than FIB-4, APRI, and NFS and Forns' index in most comparisons. CONCLUSION A non-invasive decision tree model can predict liver fibrosis risk and aid decision making.

Abstract
BACKGROUND Blood tests and transient elastography (TE), proposed as alternatives to biopsy for identifying advanced fibrosis (METAVIR-stage-F2 or greater) or cirrhosis, have never been compared using an intention to diagnose approach, with direct comparisons only, and Bayesian approach. AIM To permit more appropriate comparisons. METHODS From an overview of articles (2002-2014), we selected studies that directly compared the diagnostic accuracy of FibroTest, aspartate aminotransferase-platelet ratio index (APRI), FIB4 or TE, with biopsy as a reference, in patients with chronic hepatitis C (CHC) or B (CHB). Investigators abstracted and checked study details and quality by using pre-defined criteria. Bayesian method in intention to diagnose was the primary outcome. RESULTS Of 1321 articles identified, 71 studies including 77 groups according to aetiology (All-CB) were eligible: 37 Only-C, 28 Only-B and 12 Mixed-C-B. There were 185 direct comparisons between the area under the ROC curves (AUROCs), 99 for the diagnosis of advanced fibrosis and 86 for cirrhosis. In All-CB, Bayesian analyses revealed significant AUROCs differences in identifying advanced fibrosis in favour of FibroTest vs. TE [credibility interval: 0.06(0.02-0.09)], FibroTest vs. APRI [0.05 (0.03-0.07)] and for identifying cirrhosis TE vs. APRI [0.07 (0.02-0.13)] and FIB4 vs. APRI [0.04(0.02-0.05)]. No differences were observed between TE and FibroTest, for identifying cirrhosis in All-CB, and in sub-groups (Only-C, Only-B, Mixed-CB) for both cirrhosis and fibrosis. CONCLUSIONS In CHC and CHB, APRI had lower performances than FIB-4, TE and FibroTest. TE had lower performance than FibroTest for identifying advanced fibrosis in All-CB, without significant difference for identifying cirrhosis in all groups.

Abstract
Noninvasive serum fibrosis biomarkers predict clinical outcomes in pretransplant patients with chronic liver disease. We investigated the role of serum fibrosis biomarkers and of changes in biomarkers in predicting death and graft loss after liver transplantation (LT). We included 547 patients who underwent LT between 1991 and 2012 and who met the following criteria: patient and graft survival > 12 months; serum fibrosis biomarkers aspartate aminotransferase-to-platelet ratio index (APRI), fibrosis score 4 (FIB-4), and nonalcoholic fatty liver disease (NAFLD) fibrosis score available at 1 year after LT; and a minimum follow-up of 1 year. Delta of fibrosis biomarkers was defined as (end of follow-up score--baseline score)/follow-up duration. Baseline and delta fibrosis biomarkers were associated with death: APRI > 1.5 (adjusted hazard ratio [aHR], 2.2; 95% confidence interval [CI], 1.4-3.3; P < 0.001) and delta APRI > 0.5 (aHR, 5.3; 95% CI, 3.4-8.2; P < 0.001); FIB-4 > 3.3 (aHR, 1.9; 95% CI, 1.3-2.8; P = 0.002) and delta FIB-4 > 1.4 (aHR, 2.4; 95% CI, 1.4-4.1; P = 0.001); and NAFLD fibrosis score > 0.7 (aHR, 1.9; 95% CI, 1.3-2.9; P = 0.002) and delta NAFLD fibrosis score (aHR, 3.7; 95% CI, 2.6-5.4; P < 0.001). Baseline and delta fibrosis biomarkers were associated also with graft loss. In conclusion, serum fibrosis biomarkers 1 year after LT and changes in serum fibrosis biomarkers predict death and graft loss in LT recipients. They may help in risk stratification of LT recipients and identify patients requiring closer monitoring.

Abstract
OBJECTIVES The risk of advanced fibrosis in nonalcoholic fatty liver disease (NAFLD) is traditionally assessed with a liver biopsy, which is both costly and associated with adverse events. METHODS We sought to compare the cost-effectiveness of four different strategies to assess fibrosis risk in patients with NAFLD: vibration controlled transient elastography (VCTE), the NAFLD fibrosis score (NFS), combination testing with NFS and VCTE, and liver biopsy (usual care). We developed a probabilistic decision analytical microsimulation state-transition model wherein we simulated a cohort of 10,000 50-year-old Americans with NAFLD undergoing evaluation by a gastroenterologist. VCTE performance was obtained from a prospective cohort of 144 patients with NAFLD. RESULTS Both the NFS alone and the NFS/VCTE strategies were cost effective at $5,795 and $5,768 per quality-adjusted life years (QALY), respectively. In the microsimulation, the NFS alone and NFS/VCTE strategies were the most cost-effective (dominant) in 66.8 and 33.2% of samples given a willingness-to-pay threshold of $100,000 per QALY. In a sensitivity analysis, the minimum cost per liver biopsy at which the NFS is cost saving is $339 and the maximum cost per VCTE exam at which the NFS/VCTE strategy remains cost saving is $1,593. The expected value of further research on this topic is $526 million. CONCLUSIONS Non-invasive risk stratification with both the NFS alone and the NFS/VCTE are cost-effective strategies for the evaluation and management of patients with NAFLD presenting to a gastroenterologist. Further research is needed to better define the natural history of NAFLD and the effect of novel treatments on decision making.

Abstract
Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) are chronic, cholestatic diseases of the liver with common clinical manifestations. Early diagnosis and treatment of PBC slows progression and decreases the need for transplant. However, one-third of patients will progress regardless of treatment. Bilirubin <1.0 and alkaline phosphatase <2.0 x the upper limit of normal at 1 year after treatment appear to predict 10-year survival. Ursodeoxycholic acid (UDCA) is the recommended treatment for PBC, and recent studies with obeticholic acid showed promising results for UDCA non-responders. Unlike PBC, no therapy has been shown to alter the natural history of PSC. The recommended initial diagnostic test for PSC is magnetic resonance cholangiopancreatography, typically showing bile duct wall thickening, focal bile duct dilatation, and saccular dilatation of the intra- and/or extrahepatic bile ducts. Immunoglobulin 4-associated cholangitis must be excluded when considering the diagnosis of PSC, to allow for proper treatment, and monitoring of disease progression. In addition to the lack of therapy, PSC is a pre-malignant condition and close surveillance is indicated.

Low-fasting triglyceride levels are associated with non-invasive markers of advanced liver fibrosis among adults in the United States. Aliment Pharmacol Ther 2015; 42:106-16. [PMID: 25913437 DOI: 10.1111/apt.13216] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2015] [Revised: 02/22/2015] [Accepted: 04/08/2015] [Indexed: 02/06/2023]
Abstract
BACKGROUND Elevated fasting triglyceride is often associated with metabolic syndrome and non-alcoholic fatty liver disease (NAFLD), the most common form of chronic liver disease. On the other hand, as liver disease progresses, patients may develop hepatocellular dysfunction that impairs triglyceride production. AIM To test the hypothesis that lower fasting triglyceride levels may paradoxically indicate more advanced liver disease. METHODS A cross-sectional analysis of 11 947 adults aged 20 years or older without chronic viral hepatitis from the National Health and Nutrition Examination Survey 1999-2010 was performed to analyze the relationships between fasting triglyceride levels and five validated non-invasive indices of liver fibrosis, including Fibrosis 4 Score (FIB4), NAFLD Fibrosis Score (NFS), Ast-Platelet Ration Index, AST/ALT ratio and BARD. RESULTS Low-fasting triglyceride levels were consistently associated with elevated liver fibrosis indices. Individuals in the lowest quintile of triglycerides (TG) had an adjusted odds ratio (OR) of 3.0 (95% CI, 1.7-5.2; P < 0.001) for advanced fibrosis estimated by FIB4 score and OR of 1.8 (95% Cl, 1.2-2.7; P = 0.009) estimated by NFS, compared to individuals in the highest quintile. This association remained highly significant when restricted to individuals with abnormal LFTs from suspected NAFLD. This inverse relationship was continuous, and more pronounced among men and whites (P interaction <0.001 and 0.008 respectively), but not modified by age or body mass index. In addition, fasting TG had a stronger, more direct association with liver fibrosis indices than did albumin or total bilirubin. CONCLUSIONS Fasting triglyceride levels were inversely associated with liver fibrosis indicators in American adults, especially among white men. Our findings suggest that sequential lipid measurements may serve as a useful disease marker in the management of chronic liver disease patients.

Abstract
The Society of Radiologists in Ultrasound convened a panel of specialists from radiology, hepatology, pathology, and basic science and physics to arrive at a consensus regarding the use of elastography in the assessment of liver fibrosis in chronic liver disease. The panel met in Denver, Colo, on October 21-22, 2014, and drafted this consensus statement. The recommendations in this statement are based on analysis of current literature and common practice strategies and are thought to represent a reasonable approach to the noninvasive assessment of diffuse liver fibrosis.

Abstract
Objective Patients with type 2 diabetes and nonalcoholic fatty liver disease (NAFLD) have a higher prevalence of cardiovascular diseases. In this study we investigated the frequency of single nucleotide polymorphisms (SNPs) of several candidate genes associated with NAFLD in Taiwanese patients with type 2 diabetes mellitus (DM) and NAFLD and in those with DM but without fatty liver disease. Methods We enrolled 350 patients with type 2 DM and NAFLD and 209 patients with DM but without NAFLD. Body mass index (BMI), % body fat (% BF), glycated hemoglobin (HbA1c), high molecular weight (HMW) isoform of adiponectin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride (TG) levels were measured. Thirteen SNPs in 5 genes (adiponectin, leptin, peroxisome proliferator-activated receptor alpha, adiponutrin/patatin-like phospholipase domain-containing protein 3 and peroxisome proliferator-activated receptor γ co-activator 1α ) were measured. Results Only adiponectin rs266729 polymorphism was associated with susceptibility to NAFLD (p = 0.001). Subgroup analysis revealed that the proportion of subjects with homozygous genotype GG was higher in patients with NAFLD (31%) than in controls (11%) and that the proportions of heterozygous CG and homozygous CC were higher in controls (37% and 52%, respectively) than in patients with NAFLD (33% and 36%, respectively). Patients with NAFLD carrying the GG genotype of rs266729 showed significantly lower serum HMW adiponectin levels than patients carrying the GC or CC genotype (3.75±0.37 vs. 3.99±0.66 vs. 4.79±0.58 μg/ml, p< 0.001). Body fat and serum HMW adiponectin levels were the strongest predictors of developing NAFLD (p < 0.001 and 0.004, respectively). Conclusions In patients with type 2 diabetes gene polymorphism of adiponectin rs266729 is associated with risk of NAFLD. G allele of rs266729 is associated with hypoadiponectinemia. Low serum adiponectin level may precipitate liver steatosis in patients with type 2 diabetes.

Abstract
PURPOSE OF REVIEW Therapeutic advances for hepatitis C and the increasing prevalence on nonalcoholic fatty liver disease are reshaping the diagnostic approach to disease staging in clinical hepatology. Well tolerated, inexpensive and reliable alternatives to liver biopsy are a critical need for clinicians and patients alike. RECENT FINDINGS Vibration-controlled transient elastography (VCTE, also known as 'transient elastography') is a robust, point-of-care tool for the noninvasive assessment of liver fibrosis. This tool efficiently prioritizes the treatment for patients with viral hepatitis at risk for advanced liver disease and identifies the subgroups with metabolic or cholestatic liver disease who are at the highest risk. Rather than staging fibrosis, VCTE provides an accurate risk estimate of advanced fibrosis. In addition, it is increasingly recognized that elastography can predict outcomes including hepatic decompensation and mortality. The ideal use of this tool is to perform it in conjunction with a serologic marker of fibrosis to confirm its findings. SUMMARY When combined with serologic markers of fibrosis, VCTE allows the vast majority of patients to avoid a liver biopsy.

Abstract
PURPOSE OF REVIEW Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease of unknown origin. There is no medical treatment of proven benefit on survival; once patients have progressed to end-stage liver disease, the only treatment option is liver transplantation. RECENT FINDINGS Over the last years, some progress has been made in identifying biomarkers of PSC disease progression. Categories that can be distinguished include clinical and biochemical biomarkers, histology, imaging, prognostic modelling and genetics. With this review, we summarize biomarkers for progression of PSC from these six categories, which have been studied to date. SUMMARY Biomarkers for the progression of PSC disease course can be used for several purposes. First of all, they can be implemented as surrogate endpoints for clinical trials. Second, biomarkers of disease progression form the basis of prognostic modelling, which is needed for proper patient counselling and management. Lastly, these biomarkers may yield a better understanding of PSC pathogenesis.

Abstract
BACKGROUND & AIMS Liver biopsy is invasive and associated with complications, sampling errors, and observer variability. Vibration-controlled transient elastography (VCTE) with FibroScan can be used to immediately assess liver stiffness. We aimed to define optimal levels of liver stiffness to identify patients with chronic viral hepatitis and significant fibrosis, advanced fibrosis, or cirrhosis. METHODS In a prospective, 2-phase study, patients with chronic hepatitis C or B underwent VCTE followed by liver biopsy analysis from January 2005 through May 2008 at 6 centers in the United States. In phase 1 we identified optimal levels of liver stiffness for identification of patients with stage F2-F4 or F4 fibrosis (the development phase, n = 188). In phase 2 we tested these cutoff values in a separate cohort of patients (the validation phase, n = 560). All biopsies were assessed for METAVIR stage by a single pathologist in the phase 1 analysis and by a different pathologist in the phase 2 analysis. Diagnostic performances of VCTE were assessed by area under the receiver operating characteristic curve (AUROC) analyses. RESULTS In phase 1 of the study, liver stiffness measurements identified patients with ≥ F2 fibrosis with AUROC value of 0.89 (95% confidence interval, 0.83-0.92) and identified patients with F4 fibrosis with AUROC value of 0.92 (95% confidence interval, 0.87-0.95). Liver stiffness cutoff values (kPa) in phase 1 were 8.4 for ≥ F2 (82% sensitivity, 79% specificity) and 12.8 for F4 (84% sensitivity, 86% specificity). In the phase 2 analysis, the liver stiffness cutoff values identified patients with ≥ F2 fibrosis with 58% sensitivity (P < .0001 vs phase 1) and 75% specificity (nonsignificant difference vs phase 1); they identified patients with F4 fibrosis with 76% sensitivity (P < .0001 vs phase 1) and 85% specificity (nonsignificant differences vs phase 1). VCTE had an interobserver agreement correlation coefficient of 0.98 (n = 26) and an intraobserver agreement correlation coefficient of 0.95 (n = 34). CONCLUSIONS In a large U.S. multicenter study, we confirmed that VCTE provides an accurate assessment of liver fibrosis in patients with chronic viral hepatitis. Our findings are similar to those from European and Asian cohorts.

Abstract
There are an estimated 40 million HIV infected individuals worldwide, with chronic liver disease being the 2nd leading cause of mortality in this population. Elevated liver functions are commonly noted in HIV patients and the etiologies are varied. Viral hepatitis B and C, fatty liver and drug induced liver injury are more common. Treatment options for viral hepatitis C are rapidly evolving and are promising, but treatments are limited for the other conditions and is primarily supportive. Opportunistic infections of the liver are now uncommon. Irrespective of etiology, management requires referral to specialized centers and with due diligence mortality can be reduced.

Abstract
Newer noninvasive tests have begun to replace liver biopsy for staging purposes. The clinician must evaluate these tools and apply them to individual patients. None of these modalities give the exact same staging of fibrosis as a liver biopsy, but they are excellent tools for risk stratification. Still, it should be recognized that there are disease-specific issues with different utilizations and cutoffs for different clinical diseases. This article provides a framework for incorporating the use of serum biomarkers and elastography-based approaches to stage fibrosis into clinical practice. This review also covers recent developments in this rapidly advancing area.
