Abstract
Various types of liver disease exist, such as hepatitis and alcoholic liver disease. These liver diseases can result in scarring of liver tissue, cirrhosis, and finally liver failure. During liver fibrosis, there is an excess and disorganized accumulation of extracellular matrix (ECM) components which cause the loss of normal liver cell functions. For patients with chronic liver disease, fibrosis prediction is an essential part of the assessment and management. To diagnose liver fibrosis, several invasive and noninvasive markers have been proposed. However, the adoption of invasive markers remains limited due to their inherent characteristics and poor patient acceptance rate. In contrast, noninvasive markers can expedite the clinical decision through informed judgment about disease stage and prognosis. These noninvasive markers are classified into two types: Imaging techniques and serum biomarkers. However, the diagnostic values of biomarkers associated with liver fibrosis have also been analyzed. For example, the serum levels of ECM proteins can react to either matrix accumulation or degradation. During virus-host interactions, several regulatory steps take place to control gene expression, such as the change in cellular microRNA expression profiles. MicroRNAs are a class of non-coding RNAs (18-20 long nucleotides) that function by post-transcriptional regulation of gene expression. Although various noninvasive markers have been suggested in recent years, certain limitations have restricted their clinical applications. Understanding the potential of non-invasive biomarkers as a therapeutic option to treat liver fibrosis is still in progress.

Abstract
Background/Aims Acute exacerbations of chronic hepatitis B (CHB-AEs) are common in endemic areas and are often presumed to be acute hepatitis B (AHB) due to their similarities in clinical and serological pictures, presenting a major diagnostic dilemma. This study aimed to identify laboratory markers for differentiating between the two groups, and to establish the cut-off value for significant markers. Methods A retrospective analysis of records was conducted for patients who presented with clinical features of acute hepatitis along with hepatitis B surface antigen (HBsAg) and IgM antibody to hepatitis B core antigen (IgM anti-HBc) positivity from May 2015 to May 2017. A total of 172 patients were enrolled and grouped as AHB (n=89) and CHB-AE (n=83) based on their history of hepatitis B virus infection and duration of HBsAg persistence. Virological and biochemical parameters were analyzed and compared. Cut-off values, sensitivity, and specificity of the variables were calculated. Results The median value of signal by cut-off (S/Co) ratio for IgM anti-HBc was significantly higher in AHB group (30.44) compared to CHB-AE group (8.63) with a sensitivity and specificity of 97% and 84%, respectively, at a cut-off of 20.5 (P<0.01). The mean international normalized ratio (INR) was significantly greater in CHB-AE (1.88±1.24) group compared to AHB group (1.62±0.17) with a sensitivity and specificity of 57.9% and 45.1%, respectively, at a cut-off value of 1.27. Conclusions A value of 20.5 S/Co of IgM anti-HBc and 1.27 INR could be helpful in differentiating between AHB and CHB-AE. (Clin Mol Hepatol 2020;26:187-195)

Prospective comparison of transient elastography, point shear wave elastography, APRI and FIB-4 for staging liver fibrosis in chronic viral hepatitis. J Viral Hepat 2020; 27:437-448. [PMID: 31799740 DOI: 10.1111/jvh.13246] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Revised: 10/27/2019] [Accepted: 11/19/2019] [Indexed: 12/15/2022]
Abstract
Ultrasound-based elastography and serum indexes have been individually validated as noninvasive methods for staging liver fibrosis in chronic viral hepatitis. We aimed to compare the accuracy of transient elastography (TE), shear wave elastography (SWE), aspartate aminotransferase to platelet index (APRI) and Fibrosis-4 index (FIB-4) with the METAVIR liver fibrosis staging in viral hepatitis patients. We enrolled 121 treatment-naïve chronic hepatitis B and C monoinfected patients. All underwent liver biopsy had biochemistry tests and liver stiffness measurements by TE using M and XL probes followed by point SWE performed on the same day. The accuracy of each method for predicting different fibrosis stages was demonstrated as an area under the receiver operating characteristic (AUROC) curves. The AUROCs of TE using M and XL probes, SWE, APRI and FIB-4 were 0.771, 0.761, 0.700, 0.698 and 0.697, respectively, for significant fibrosis; 0.974, 0.973, 0.929, 0.738 and 0.859, respectively, for advanced fibrosis; and 0.954, 0.949, 0.962, 0.765 and 0.962, respectively, for cirrhosis. TE using the M probe was comparable to the XL probe in detecting all fibrosis stages. TE was superior to SWE for assessing significant fibrosis and advanced fibrosis. For cirrhosis, the performances of TE, SWE and FIB-4 were similar. APRI was least accurate in liver fibrosis staging. To conclude, for patients with viral hepatitis, TE using either M or XL probe is an effective noninvasive test for assessing liver fibrosis, particularly advanced fibrosis and cirrhosis, while SWE and FIB-4 possess an excellent accuracy in predicting cirrhosis.

Abstract
Sustained virologic response (SVR) after direct acting antiviral agents (DAAs) holds promise for reducing hepatocellular cancer (HCC). DAAs have recently been available long enough to estimate the long-term risk. We conducted a retrospective cohort study of hepatitis C virus (HCV) patients who achieved SVR with DAAs from 129 Veterans Health Administration hospitals between January 1, 2015, and December 31, 2015, with follow-up through September 30, 2018. We calculated the overall and quarterly HCC incidence rates. We examined the effect of demographic, clinical, and behavioral factors and the decline or increase of FIB-4 and aspartate aminotransferase to platelet ratio index (APRI) on HCC risk. Among the 18,076 patients with SVR, 544 incident cases of HCC were diagnosed during the mean 2.9 years of follow-up. The cumulative 1, 2, and 3-year risks of HCC were 1.1%, 1.9% and 2.8%, respectively. Cirrhosis was strongly associated with HCC risk (adjusted hazard ratio = 4.13, 95% confidence interval = 3.34-5.11). The quarterly incidence rate of HCC remained stable between 1.00 and 1.23/100 person-years (PY) and 1.5 to 2.3/100 PY in patients with cirrhosis. The risk of HCC was the highest in patients who had persistently high FIB-4/APRI and both with and without cirrhosis. HCC risk fell in patients with cirrhosis who experienced a decrease of FIB-4/APRI scores yet remained higher than the accepted threshold for HCC surveillance. HCC risk was also higher in patients with alcohol use, older age, and infection with HCV genotype 3. Most patients treated at an early stage of liver fibrosis had a stable low risk. Conclusion: Patients successfully treated with DAAs and at risk of HCC did not regress after 3.6 years of follow-up. HCC risk remained above the accepted thresholds for surveillance in patients with cirrhosis. These data have important implications for HCC surveillance in cured HCV patients.

Abstract
BACKGROUND In Europe, the prevalence rates of schistosomiasis and HBV infection in migrants from sub-Saharan Africa are high. The co-infection schistosomiasis-HBV has been scarcely studied. METHODS This is a retrospective study assessing differences in clinical presentation, laboratory and ultrasound findings in a cohort of migrants admitted at the Department of Infectious - Tropical Diseases and Microbiology IRCCS Sacro Cuore Don Calabria Hospital of Negrar (Northeast Italy) with schistosomiasis, HBV infection or both. RESULTS Of the 227 migrants, 175 (77.1%) with a diagnosis of schistosomiasis were classified as SCHISTO group, 35 (15.4%) with schistosomiasis and hepatitis B were classified as SCHISTO/HBV group, and 17 (7.5%) patients with a diagnosis of HBV infection were classified as HBV group. S. mansoni was found in 47 patients, classified in MANSONI (38/175, 21.7%) or MANSONI/HBV (9/35, 25.7%) group depending on HBsAg status. Mean transaminases and APRI index values were higher in SCHISTO/HBV compared to SCHISTO group (p < 0.01). AST differed between MANSONI/HBV and MANSONI group (p = 0.038). No differences were found between SCHISTO/HBV and HBV group. Eosinophil count and total IgE differed only between MANSONI/HBV and HBV group (p = 0,049). CONCLUSIONS Schistosomiasis seems not to increase the liver damage in people with HBV infection. Conversely, finding elevated transaminases in patients with schistosomiasis should alert for presence of HBV.

Abstract
Background: The prevalence of morbidity and mortality associated with liver disease among HIV-infected individuals on combination antiretroviral therapy (ART) is high. Early screening of liver disease is essential, as it provides an opportunity for successful treatment. Hence, there is a need for reliable, inexpensive and non-invasive early markers of hepatic damage.Objectives: Non-invasive algorithms are available for assessing the extent of liver fibrosis as markers of ongoing inflammatory damage. This study compared the use of the FibroTest, Fibrosis-4 (FIB-4) index, APRI test and AST:ALT ratio in assessing liver fibrosis in combination ART-experienced individuals.Methods: In a comparative cross-sectional study, 79 participants between the ages of 8 and 62 years were recruited. The performance of each fibrosis algorithm was determined using established cut-off scores for clinically significant liver fibrosis.Results: The prevalence of liver fibrosis as determined by the FibroTest, FIB-4 index, APRI test and AST: ALT ratio were 19.0%, 21.5%, 12.7% and 79.7%, respectively. For individual biomarkers, A-2M concentration (p < 0.001) and AST activity (p = 0.003) remained significantly elevated in participants with fibrosis than those without as defined by FibroTest and APRI test, respectively, after adjustments for multiple comparisons.Conclusion: Our data demonstrate a high prevalence of asymptomatic liver fibrosis among combination ART-experienced individuals in Zimbabwe, and this warrants adequate monitoring of liver fibrosis in individuals on ART. Discordance of fibrosis results among the algorithms and individual biomarkers and calls for further work in identifying optimal biomarkers for detection of asymptomatic fibrosis.Keywords: Liver fibrosis; Non-invasive methods; Biomarkers; Combination anti-retroviral therapy; Zimbabwe.

Abstract
OBJECTIVES Several non-invasive markers have recently been proposed to predict liver fibrosis without percutaneous liver biopsy (PLB). We aimed to evaluate the performance of non-invasive scores and to highlight the value of a new combined score in the prediction of liver fibrosis in chronic hepatitis B (CHB) patients. PATIENTS AND METHODS We performed a retrospective study of patients presenting with CHB who underwent PLB between 2008 and 2016. We calculated ASAT/Platelet Ratio Index (APRI), Fibrosis-4 Score (FIB4), GGT-to-platelet ratio (GPR), and ASAT/ALAT Ratio (AAR). Then, we combined APRI and FIB-4 scores into a new combined score. We assessed their performance in predicting liver fibrosis according to the Metavir score. RESULTS A total of 179 patients presenting with CHB were included. Multivariate analysis showed that the APRI score was the only independent factor of significant fibrosis (OR=3.78; P=0.02), whereas the FIB-4 score was the only independent factor for severe fibrosis (OR=2.85; P<0.001) and cirrhosis (OR=2.5; P=0.001). At a threshold of severe fibrosis, APRI had the best specificity (75%) and FIB-4 had the greatest sensitivity (74%). Using the combined score, we improved the diagnostic performance of APRI and FIB-4 scores at the three thresholds of liver fibrosis. With this combined score, maximum 25.1% of patients presenting with CHB would undergo PLB. CONCLUSION APRI, FIB-4, and GPR scores were well performing to predict liver fibrosis during CHB. The new combined score using APRI and FIB-4 was more accurate at the three-fibrosis thresholds.

Abstract
Liver fibrosis (LF), a common consequence of chronic liver diseases with various etiologies, is characterized by excessive accumulation of macromolecules, including collagen, glycoproteins and proteoglycans, in the liver. LF can result in hepatic dysfunction, cirrhosis, portal hypertension and, in some cases, hepatocellular carcinoma. As the current gold standard for diagnosing LF, liver biopsy, however, is invasive and prone to sampling errors and procedure-related complications. Therefore, developing noninvasive, precise and reproducible imaging tests for diagnosing and staging LF is of great significance. Conventional ultrasound (US), computed tomography (CT) and magnetic resonance (MR) imaging can depict morphological alterations of advanced LF, but have relatively limited capability characterizing early-stage LF. In order to optimize the diagnostic performances of noninvasive imaging techniques for LF across its entire spectrum of severity, a number of novel methods, including US elastography, CT perfusion imaging and various MR imaging-based techniques, have been established and introduced to clinical practice. In this review, we intended to summarize current noninvasive imaging techniques for LF, with special emphasis on the possible roles, advantages and limitations of the new emerging imaging modalities.

Abstract
Aim This systematic review and meta-analysis was carried out to compare the diagnostic accuracy of Magnetic resonance elastography (MRE) and Fibroscan for detecting liver fibrosis in Chronic Hepatitis B (CHB) patients. Methods The PubMed, the Cochrane Library, and the Web of science databases were searched for studies that evaluated the diagnostic value of MRE and Fibroscan for liver fibrosis in CHB patients until March 1st 2017. The quality of the included studies was assessed by the revised Quality Assessment for Studies of Diagnostic Accuracy tool (QUADAS-2). Meta-disc 4.1 was used to summary the area under receiver operating characteristics curve (AUROC), sensitivity, specificity, diagnostic odds ratios to assess the accuracy of staging liver fibrosis using MRE and Fibroscan. Results A total of nine MRE studies with 1470 patients and fifteen Fibroscan studies with 3641 patients were included in this systematic review. The summary AUROC values using MRE and Fibroscan for detecting significant fibrosis, advanced fibrosis and cirrhosis were 0.981 vs. 0.796(p<0.001), 0.972 vs. 0.893(p<0.001), and 0.972 vs. 0.905 (p<0.001). The pooled sensitivity and specificity using MRE for the diagnosis of significant fibrosis, advanced fibrosis and cirrhosis were 92.8% and 93.7%, 89.6% and 93.2%, 89.5% and 92.0%, respectively. The pooled sensitivity and specificity using Fibroscan for the diagnosis of significant fibrosis, advanced fibrosis and cirrhosis were 71.6% and 81.6%, 79.0% and 84.6%, 80.0% and 86.6%, respectively. Conclusion MRE is more accurate than Fibroscan in diagnosing liver fibrosis in CHB patients, especially in diagnosing significant fibrosis and advanced fibrosis.

Abstract
Objectives: The accurate assessment of liver fibrosis is clinically important in patients with chronic hepatitis B (CHB). Blood tests and elastography are now widely used for the noninvasive diagnosis of liver fibrosis in CHB patients. The aim of this study was to develop a new and more accurate predictive model, which combines elastography data, serum biomarkers, and individual characteristics, to discriminate between CHB patients with and without significant liver fibrosis. Methods: Two noninvasive methods, specifically, an ultrasound elastography technique termed acoustic radiation force impulse imaging (ARFI) and a blood test, were used to assess a cohort of 345 patients (estimation group, 218 patients; validation group, 127 patients) with CHB. Multivariate logistic regression analysis revealed that ARFI, the aspartate aminotransferase (AST) to platelet ratio, and age were significantly associated with fibrosis. Based on these results, we constructed and validated a model for the diagnosis of significant hepatic fibrosis. Results: The area under the receiver operating characteristic (ROC) curve was 0.921 for the estimation group and 0.929 for the validation group, significantly higher than those for ARFI (0.887, 0.893) and for the AST-to-platelet ratio index (APRI; 0.811, 0.859). Using an optimal cutoff of 3.05 in the validation group, all the indices of the proposed model, including accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic odds ratio, were better than those for ARFI or APRI. Conclusions: We developed a simple noninvasive model that used ultrasound elastography, routine serum biomarkers, and individual characteristics to accurately differentiate significant fibrosis in patients with CHB. Compared with elastography or the biomarker index alone, this model was significantly more accurate and robust.

Abstract
Liver biopsy is the best method for detecting fibrosis grade of the liver in chronic hepatitis B. However, the invasiveness of liver biopsy complicates its routine use in follow-up of treatment. We planned to determine the usage of fibrosis predicting noninvasive scores in the follow-up of the treatment of patients with chronic hepatitis B treated with entecavir or tenofovir. Two hundred twenty-eight patients with hepatitis B with liver biopsy were included in the study. Fibrosis grade was determined by Ishak score. The laboratory data at months 0, 12, and 24 during treatment were collected and noninvasive fibrosis scores (aspartate aminotransferase to alanine aminotransferase ratio [AAR], aspartate aminotransferase to platelet ratio index [APRI], fibrosis index based on the 4 factors [FIB-4] and red cell distribution width to platelet ratio [RPR]) were calculated. Statistically significant increase in all scores and decrease in platelet count were observed as the fibrosis level increased. For differentiation of patients with fibrosis ≥grade 2, the highest sensitivity and specificity rates were shown by APRI score (sensitivity 67%, specificity 69%, and cutoff ≥0.5). FIB-4 was the most successful score for differentiation of patients with fibrosis ≥grade 3 (sensitivity 83%, specificity 74%, and cutoff ≥1.45). A significant decrease in all noninvasive fibrosis scores was observed at months 12 and 24 during treatment with both entecavir and tenofovir (P < 0.001). Among these, only the improvement in APRI score was found better in entecavir group with statistical significance (P < 0.05). APRI score was effective in demonstrating early-stage fibrosis. FIB-4, RPR, and platelet count were better in demonstrating advanced fibrosis. Although noninvasive scores cannot replace liver biopsy for diagnosis, they can be used for monitoring the response to treatment.

Abstract
Schistosomiasis is related to the development of liver fibrosis and portal hypertension. Chronic co-infection with HBV and Schistosoma has been associated in endemic areas with a higher risk for a more severe liver disease. However, no studies have assessed the real importance of this co-infection in non-endemic regions. This is a retrospective observational study of Sub-Saharan immigrants attending between October 2004 and February 2014. Patients with chronic HBV infection with and without evidence of schistosomal infection were compared. Epidemiological, analytical, and microbiological data were analysed. Likelihood of liver fibrosis based on APRI and FIB-4 indexes was established. A total of 507 patients were included in the study, 170 (33.5 %) of them harbouring evidence of schistosome infection. No differences were found in transaminase, GGT, and ALP levels. In fibrosis tests, a higher proportion of patients with HVB and S. mansoni detection reached possible fibrosis scores (F > 2) when compared to patients without schistosomiasis: 17.4 vs 14.2 % and 4.3 % vs 4.2 % (using high sensitivity and high specificity cut-offs respectively), although differences were not statistically significant (p = 0.69, p = 0.96). For possible cirrhosis (F4) score, similar results were observed: 4.3 % of co-infected patients vs 2.1 % of mono-infected ones, p = 0.46. According to these datas, in non-endemic regions the degree of hepatic fibrosis in patients with chronic hepatitis B is not substantially modified by schistosome co-infection.

Abstract
Hepatic fibrogenesis may gradually result to cirrhosis due to the accumulation of extracellular matrix components as a response to liver injury. Thus, therapeutic decisions in chronic liver disease, regardless of the cause, should first and foremost be guided by an accurate quantification of hepatic fibrosis. Detection and assessment of the extent of hepatic fibrosis represent a challenge in modern Hepatology. Although traditional histological staging systems remain the “best standard”, they are not able to quantify liver fibrosis as a dynamic process and may not accurately substage cirrhosis. This review aims to compare the currently used non-invasive methods of measuring liver fibrosis and provide an update in current tissue-based digital techniques developed for this purpose, that may prove of value in daily clinical practice.

Abstract
In this study, we put forward a new approach to classify early stages of fibrosis based on a multiparametric characterization using backscatter ultrasonic signals. Ultrasonic parameters, such as backscatter coefficient (Bc), speed of sound (SoS), attenuation coefficient (Ac), mean scatterer spacing (MSS), and spectral slope (SS), have shown their potential to differentiate between healthy and pathologic samples in different organs (eye, breast, prostate, liver). Recently, our group looked into the characterization of stages of hepatic fibrosis using the parameters cited above. The results showed that none of them could individually distinguish between the different stages. Therefore, we explored a multiparametric approach by combining these parameters in two and three, to test their potential to discriminate between the stages of liver fibrosis: F0 (normal), F1, F3, and/without F4 (cirrhosis), according to METAVIR Score. Discriminant analysis showed that the most relevant individual parameter was Bc, followed by SoS, SS, MSS, and Ac. The combination of (Bc, SoS) along with the four stages was the best in differentiating between the stages of fibrosis and correctly classified 85% of the liver samples with a high level of significance (p<0.0001). Nevertheless, when taking into account only stages F0, F1, and F3, the discriminant analysis showed that the parameters (Bc, SoS) and (Bc, Ac) had a better classification (93%) with a high level of significance (p<0.0001). The combination of the three parameters (Bc, SoS, and Ac) led to a 100% correct classification. In conclusion, the current findings show that the multiparametric approach has great potential in differentiating between the stages of fibrosis, and thus could play an important role in the diagnosis and follow-up of hepatic fibrosis.

Abstract
Oxaliplatin-based regimens are standard treatments for the patients with colorectal cancer (CRC) and advanced gastric cancer (AGC). However, owing to hepatic sinusoidal obstruction syndrome (SOS), the use of oxaliplatin sometimes results in splenomegaly. The aim of the present study was to evaluate the correlation between chemotherapy-associated changes of noninvasive liver fibrosis indices and volumetric changes of the spleen.From February 2004 to April 2014, patients with CRC or AGC receiving oxaliplatin-based chemotherapy were studied. The possibility of SOS development was evaluated before and after the oxaliplatin exposure with splenic volume index (SVI). Four different noninvasive liver fibrosis indices were used for risk analysis, namely age-platelet index (API), AST-to-platelet ratio index (APRI), platelet-to-spleen ratio (PSR), and fibrosis-4 score (FIB-4).A total of 275 patients were eligible for evaluation: 200 patients had CRC and 75 patients had AGC. Using the cutoff of SVI increase ≥ 0.3, 113 patients (41.1%) were positive for splenomegaly. The changes of indices significantly correlated with SVI increase. Adjusted odds ratios for those indices were as follows: API = 1.16 (95% confidential interval [CI], 1.01-1.32; P = .03); APRI = 2.45 (95% CI, 1.30-4.63; P = .01); PSR = 0.69 (95% CI, 0.59-0.80; P < .01); and FIB-4 = 1.37 (95% CI, 1.16-1.63; P < .01). Optimal cutoff values with statistical significance were calculated and suggested.The changes of noninvasive liver fibrosis indices showed a good correlation with the increase in the spleen volume during oxaliplatin-based chemotherapy. Validation of these indices for monitoring of oxaliplatin-induced hepatic SOS is warranted.

Abstract
BACKGROUND Liver biopsy is the reference standard for diagnosing the extent of fibrosis in chronic liver disease; however, it is invasive, with the potential for serious complications. Alternatives to biopsy include non-invasive liver tests (NILTs); however, the cost-effectiveness of these needs to be established. OBJECTIVE To assess the diagnostic accuracy and cost-effectiveness of NILTs in patients with chronic liver disease. DATA SOURCES We searched various databases from 1998 to April 2012, recent conference proceedings and reference lists. METHODS We included studies that assessed the diagnostic accuracy of NILTs using liver biopsy as the reference standard. Diagnostic studies were assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Meta-analysis was conducted using the bivariate random-effects model with correlation between sensitivity and specificity (whenever possible). Decision models were used to evaluate the cost-effectiveness of the NILTs. Expected costs were estimated using a NHS perspective and health outcomes were measured as quality-adjusted life-years (QALYs). Markov models were developed to estimate long-term costs and QALYs following testing, and antiviral treatment where indicated, for chronic hepatitis B (HBV) and chronic hepatitis C (HCV). NILTs were compared with each other, sequential testing strategies, biopsy and strategies including no testing. For alcoholic liver disease (ALD), we assessed the cost-effectiveness of NILTs in the context of potentially increasing abstinence from alcohol. Owing to a lack of data and treatments specifically for fibrosis in patients with non-alcoholic fatty liver disease (NAFLD), the analysis was limited to an incremental cost per correct diagnosis. An analysis of NILTs to identify patients with cirrhosis for increased monitoring was also conducted. RESULTS Given a cost-effectiveness threshold of £20,000 per QALY, treating everyone with HCV without prior testing was cost-effective with an incremental cost-effectiveness ratio (ICER) of £9204. This was robust in most sensitivity analyses but sensitive to the extent of treatment benefit for patients with mild fibrosis. For HBV [hepatitis B e antigen (HBeAg)-negative)] this strategy had an ICER of £28,137, which was cost-effective only if the upper bound of the standard UK cost-effectiveness threshold range (£30,000) is acceptable. For HBeAg-positive disease, two NILTs applied sequentially (hyaluronic acid and magnetic resonance elastography) were cost-effective at a £20,000 threshold (ICER: £19,612); however, the results were highly uncertain, with several test strategies having similar expected outcomes and costs. For patients with ALD, liver biopsy was the cost-effective strategy, with an ICER of £822. LIMITATIONS A substantial number of tests had only one study from which diagnostic accuracy was derived; therefore, there is a high risk of bias. Most NILTs did not have validated cut-offs for diagnosis of specific fibrosis stages. The findings of the ALD model were dependent on assuptions about abstinence rates assumptions and the modelling approach for NAFLD was hindered by the lack of evidence on clinically effective treatments. CONCLUSIONS Treating everyone without NILTs is cost-effective for patients with HCV, but only for HBeAg-negative if the higher cost-effectiveness threshold is appropriate. For HBeAg-positive, two NILTs applied sequentially were cost-effective but highly uncertain. Further evidence for treatment effectiveness is required for ALD and NAFLD.

Abstract
BACKGROUND Liver fibrosis is characterized by a buildup of connective tissue due to chronic liver damage. Steatosis is the collection of excessive amounts of fat inside liver cells. Liver biopsy remains the gold standard for the diagnosis of liver fibrosis and steatosis, but its use as a diagnostic tool is limited by its invasive nature and high cost. OBJECTIVES To evaluate the cost-effectiveness and budget impact of transient elastography (TE) with and without controlled attenuation parameter (CAP) for the diagnosis of liver fibrosis or steatosis in patients with hepatitis B, hepatitis C, alcoholic liver disease, and nonalcoholic fatty liver disease. DATA SOURCES An economic literature search was performed using computerized databases. For primary economic and budget impact analyses, we obtained data from various sources, such as the Health Quality Ontario evidence-based analysis, published literature, and the Institute for Clinical Evaluative Sciences. REVIEW METHODS A systematic review of existing TE cost-effectiveness studies was conducted, and a primary economic evaluation was undertaken from the perspective of the Ontario Ministry of Health and Long-Term Care. Decision analytic models were used to compare short-term costs and outcomes of TE compared to liver biopsy. Outcomes were expressed as incremental cost per correctly diagnosed cases gained. A budget impact analysis was also conducted. RESULTS We included 10 relevant studies that evaluated the cost-effectiveness of TE compared to other noninvasive tests and to liver biopsy; no cost-effectiveness studies of TE with CAP were identified. All studies showed that TE was less expensive but associated with a decrease in the number of correctly diagnosed cases. TE also improved quality-adjusted life-years in patients with hepatitis B and hepatitis C. Our primary economic analysis suggested that TE led to cost savings but was less effective than liver biopsy in the diagnosis of liver fibrosis. TE became more economically attractive with a higher degree of liver fibrosis. TE with CAP was also less expensive and less accurate than liver biopsy. LIMITATIONS The model did not take into account long-term costs and consequences associated with TE and liver biopsy and did not include costs to patients and their families, or patient preferences related to diagnostic information. CONCLUSIONS TE showed potential cost savings compared to liver biopsy. Further investigation is needed to determine the long-term impacts of TE on morbidity and mortality in Canada and the optimal diagnostic modality for liver fibrosis and steatosis.

Abstract
BACKGROUND & AIMS Advanced liver fibrosis is associated with recurrence after curative resection of hepatocellular carcinoma (HCC). This study aimed to investigate whether noninvasive fibrosis indices could predict intrahepatic recurrence and death after curative resection of HCC. METHODS Patients who underwent curative resection for hepatitis B virus (HBV)-related HCC between 2006 and 2010 at a single tertiary hospital were included. This study analysed the association of noninvasive fibrosis indices with recurrence and overall survival. RESULTS A total of 303 patients were included. During a median follow-up period of 56.0 (interquartile range, 42.0-70.0) months, 151 (49.8%) patients experienced HCC recurrence and 54 (17.8%) died. Based on multivariate analysis, Forns index [hazard ratio (HR), 1.238; 95% confidence interval (CI), 1.097-1.398; P = 0.001] was independently associated with tumour recurrence after adjustment for anti-HBe positivity, histological cirrhosis, tumour size and number. Patients with Forns index <6.9 had a significantly longer recurrence-free survival rate than patients with Forns index ≥6.9 (P < 0.001 by log-rank test). Forns index (HR, 1.246; 95% CI, 1.034-1.501; P = 0.02) could also predict overall survival after adjustment for tumour size and number. Forns index detected cirrhosis with an AUROC of 0.700 (95% CI, 0.641-0.758). Aspartate aminotransferase-to-platelet ratio index, cirrhosis discriminant score, FIB-4 index, P2/MS and Lok index detected cirrhosis comparably to Forns index, but were not associated with tumour recurrence or death. CONCLUSIONS Our data suggest that Forns index could be a useful predictor of recurrence and overall survival after curative resection of HBV-related HCC.

Abstract
BACKGROUND Among various preoperative evaluations of liver function, accurate assessment of liver cirrhosis (LC) is especially important in patients undergoing surgery for hepatocellular carcinoma (HCC). OBJECTIVE To explore the most significant laboratory parameter associated with LC in patients undergoing surgery for HCC. METHODS From among 588 HCC patients in our collected database who underwent liver surgery, 371 for whom sufficient laboratory data were evaluable, including direct serum fibrosis markers such as hyaluronic acid and type 3 procollagen peptide (P-3-P), were enrolled. Receiver operating characteristic (ROC) curve analysis was used to define the ideal cutoff values of laboratory parameters, and the area under the ROC curve for LC was measured. Univariate and multivariate analyses were performed to clarify the laboratory parameter most significantly associated with LC. RESULTS Multivariate analysis of 13 laboratory parameters that had been selected by univariate analysis showed that the aspartate aminotransferase-to-platelet ratio index (APRI) (≤ 0.8/>0.8) (odds ratio, 2.687; 95% confidence interval 1.215-5.940; P = 0.015) was associated with LC, along with the aspartate aminotransferase to alanine aminotransferase ratio, the indocyanine green retention ratio at 15 min (ICG R15), and the level of hyaluronic acid. Among these four parameters associated with LC, ROC curve analysis revealed that APRI (0.757) had the largest area under the ROC (aspartate aminotransferase to alanine aminotransferase 0.505, ICG R15 0.714, and hyaluronic acid 0.743). CONCLUSIONS APRI is closely associated with LC in patients undergoing surgery for HCC.

BMC Gastroenterol 2014; 14:118. [PMID: 24990385 PMCID: PMC4086988 DOI: 10.1186/1471-230x-14-118] [Citation(s) in RCA: 7] [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: 03/19/2014] [Accepted: 06/19/2014] [Indexed: 12/19/2022] Open
Abstract
Background Noninvasive markers of liver fibrosis have not been extensively studied in patients with chronic hepatitis B virus (HBV) infection. Our aim was to evaluate the capacity of FibroSURE, one of the two noninvasive fibrosis indices commercially available in the United States, to identify HBV infected patients with moderate to severe fibrosis. Methods Forty-five patients who underwent liver biopsy at a single tertiary care center were prospectively enrolled and had FibroSURE performed within an average interval of 11 days of the biopsy. Results Of the 45 patients, 40% were Asian, 40% were African American, and 13% were Caucasian; 27% were co-infected with HIV and 67% had no or mild fibrosis. We found FibroSURE to have moderate capacity to discriminate between patients with moderate to high fibrosis and those with no to mild fibrosis (area under receiver operating characteristic [AUROC] curve = 0.77; 95% confidence interval [CI] [0.61, 0.92]). When we combined the fibrosis score determined by FibroSURE with aspartate aminotransferase (AST) measurements and HIV co-infection status, the discriminatory ability significantly improved reaching an AUROC of 0.90 (95% CI [0.80, 1.00]). FibroSURE also had a good ability to differentiate patients with no or mild from those with moderate to high inflammation (AUROC = 0.83; 95% CI [0.71, 0.95]). Conclusions FibroSURE in combination with AST levels has an excellent capacity to identify moderate to high fibrosis stages in chronic HBV-infected patients. These data suggest that FibroSURE may be a useful substitute for liver biopsy in chronic HBV infection.

Prospective evaluation of FibroTest®, FibroMeter®, and HepaScore® for staging liver fibrosis in chronic hepatitis B: comparison with hepatitis C. J Hepatol 2014; 61:28-34. [PMID: 24631902 DOI: 10.1016/j.jhep.2014.02.029] [Citation(s) in RCA: 58] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2013] [Revised: 01/24/2014] [Accepted: 02/22/2014] [Indexed: 12/13/2022]
Abstract
BACKGROUND & AIMS Fibrosis blood tests have been validated in chronic hepatitis C. Their diagnostic accuracy is less documented in hepatitis B. The aim of this study was to describe the diagnostic performance of FibroTest®, FibroMeter®, and HepaScore® for liver fibrosis in hepatitis B compared to hepatitis C. METHODS 510 patients mono-infected with hepatitis B or C and matched on fibrosis stage were included. Blood tests were performed the day of the liver biopsy. Histological lesions were staged according to METAVIR. RESULTS Fibrosis stages were distributed as followed: F0 n=76, F1 n=192, F2 n=132, F3 n=54, F4 n=56. Overall diagnostic performance of blood tests were similar between hepatitis B and C with AUROC ranging from 0.75 to 0.84 for significant fibrosis, 0.82 to 0.85 for extensive fibrosis and 0.84 to 0.87 for cirrhosis. Optimal cut-offs were consistently lower in hepatitis B compared to hepatitis C, especially for the diagnosis of extensive fibrosis and cirrhosis, with decreased sensitivity and negative predictive values. More hepatitis B than C patients with F ⩾3 were underestimated: FibroTest®: 47% vs. 26%, FibroMeter®: 24% vs. 6%, HepaScore®: 41% vs. 24%, p<0.01. Multivariate analysis showed that hepatitis B (0R 3.4, 95% CI 1.2-19.2, p<0.02) and low γGT (OR 7.3, 95% CI 2.0-27.0, p<0.003) were associated with fibrosis underestimation. CONCLUSION Overall the diagnostic performance of blood tests is similar in hepatitis B and C. The risk of underestimating significant fibrosis and cirrhosis is however greater in hepatitis B and cannot be entirely corrected by the use of more stringent cut-offs.

The effectiveness of noninvasive biomarkers to predict hepatitis B-related significant fibrosis and cirrhosis: a systematic review and meta-analysis of diagnostic test accuracy. PLoS One 2014; 9:e100182. [PMID: 24964038 PMCID: PMC4070977 DOI: 10.1371/journal.pone.0100182] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2013] [Accepted: 05/22/2014] [Indexed: 12/13/2022] Open
Abstract
Noninvasive biomarkers have been developed to predict hepatitis B virus (HBV)-related fibrosis owing to the significant limitations of liver biopsy. Those biomarkers were initially derived from evaluation of hepatitis C virus (HCV)-related fibrosis, and their accuracy among HBV-infected patients was under constant debate. A systematic review was conducted on records in PubMed, EMBASE and the Cochrane Library electronic databases, up until April 1st, 2013, in order to systematically assess the effectiveness and accuracy of these biomarkers for predicting HBV-related fibrosis. The questionnaire for quality assessment of diagnostic accuracy studies (QUADAS) was used. Out of 115 articles evaluated for eligibility, 79 studies satisfied the pre-determined inclusion criteria for meta-analysis. Eventually, our final data set for the meta-analysis contained 30 studies. The areas under the SROC curve for APRI, FIB-4, and FibroTest of significant fibrosis were 0.77, 0.75, and 0.84, respectively. For cirrhosis, the areas under the SROC curve for APRI, FIB-4 and FibroTest were 0.75, 0.87, and 0.90, respectively. The heterogeneity of FIB-4 and FibroTest were not statistically significant. The heterogeneity of APRI for detecting significant fibrosis was affected by median age (P = 0.0211), and for cirrhosis was affected by etiology (P = 0.0159). Based on the analysis we claim that FibroTest has excellent diagnostic accuracy for identification of HBV-related significant fibrosis and cirrhosis. FIB-4 has modest benefits and may be suitable for wider scope implementation.

Abstract
OBJECTIVES Extent of liver fibrosis is one of the most important factors in determining prognosis and the need for active treatment in chronic hepatitis B (CHB). Noninvasive alternatives such as FibroTest/Fibrosure (FT) have been developed in order to overcome the shortcomings of liver biopsy (LB). We aimed to systematically review studies describing the diagnostic accuracy of FT for predicting CHB-related fibrosis. METHODS MEDLINE and EMBASE searches and hand searching methods were performed to identify studies that assessed the diagnostic accuracy of FibroTest in HB patients using LB as a reference standard. We used a hierarchical summary receiver operating curves model and the bivariate model to produce summary receiver operating characteristic curves and pooled estimates of sensitivity and specificity. RESULTS We included 16 studies (N=2494) and 13 studies (N=1754) in the heterogenous meta-analysis for liver fibrosis and cirrhosis, respectively. The area under the hierarchical summary receiver operating curve for significant liver fibrosis and for all included studies was 0.84 (95% confidence interval (CI): 0.78-0.88). At the FT threshold of 0.48, the sensitivity, specificity, and diagnostic odds ratio (DOR) of FT for significant fibrosis were 61 (48-72%), 80 (72-86%), and 6.2% (3.3-11.9), respectively. The area under the hierarchical summary receiver operating curve for liver cirrhosis and for all included studies was 0.87 (95% CI: 0.85-0.90). At the FT threshold of 0.74, the sensitivity, specificity, and DOR of FT for cirrhosis were 62 (47-75%), 91 (88-93%), and 15.7% (8.6-28.8), respectively. CONCLUSIONS FibroTest is of value in exclusion of patients with CHB-related cirrhosis, but has suboptimal accuracy in the detection of significant fibrosis and cirrhosis. It is necessary to further improve the test or combine it with other noninvasive modalities in order to improve accuracy.

Abstract
Liver fibrosis is the final common pathway for almost all causes of chronic liver injury. Liver fibrosis is now known to be a dynamic process having significant potential for resolution. Therefore, fibrosis prediction is an essential part of the assessment and management of patients with chronic liver disease. As such, there is strong demand for reliable liver biomarkers that provide insight into disease etiology, diagnosis, therapy, and prognosis in lieu of more invasive approaches such as liver biopsy. Current diagnostic strategies range from use of serum biomarkers to more advanced imaging techniques including transient elastography and magnetic resonance imaging. In addition to these modalities, there are other approaches including the use of novel, but yet to be validated, biomarkers. In this chapter, we discuss the biomarkers of liver fibrosis including the use of invasive and noninvasive biomarkers and disease-specific biomarkers in various chronic liver diseases.

Abstract
Chronic liver diseases of differing etiologies are among the leading causes of mortality and morbidity worldwide. Establishing accurate staging of liver disease is very important for enabling both therapeutic decisions and prognostic evaluations. A liver biopsy is considered the gold standard for assessing the stage of hepatic fibrosis, but it has many limitations. During the last decade, several noninvasive markers for assessing the stage of hepatic fibrosis have been developed. Some have been well validated and are comparable to liver biopsy. This paper will focus on the various noninvasive biochemical markers used to stage liver fibrosis.

Abstract
BACKGROUND The assessment of liver fibrosis in chronic hepatitis C patients is important for prognosis and making decisions regarding antiviral treatment. Although liver biopsy is considered the reference standard for assessing hepatic fibrosis in patients with chronic hepatitis C, it is invasive and associated with sampling and interobserver variability. Serum fibrosis markers have been utilized as surrogates for a liver biopsy. METHODS We completed a prospective study of 191 patients in which blood draws and liver biopsies were performed on the same visit. Using liver biopsies the sensitivity, specificity, and negative and positive predictive values for both aspartate aminotransferase/platelet ratio index (APRI) and enhanced liver fibrosis (ELF) were determined. The patients were divided into training and validation patient sets to develop and validate a clinically useful algorithm for differentiating mild and significant fibrosis. RESULTS The area under the ROC curve for the APRI and ELF tests for the training set was 0.865 and 0.880, respectively. The clinical sensitivity in separating mild (F0-F1) from significant fibrosis (F2-F4) was 80% and 86.0% with a clinical specificity of 86.7% and 77.8%, respectively. For the validation sets the area under the ROC curve for the APRI and ELF tests was, 0.855 and 0.780, respectively. The clinical sensitivity of the APRI and ELF tests in separating mild (F0-F1) from significant (F2-F4) fibrosis for the validation set was 90.0% and 70.0% with a clinical specificity of 73.3% and 86.7%, respectively. There were no differences between the APRI and ELF tests in distinguishing mild from significant fibrosis for either the training or validation sets (P=0.61 and 0.20, respectively). Using APRI as the primary test followed by ELF for patients in the intermediate zone, would have decreased the number of liver biopsies needed by 40% for the validation set. Overall, use of our algorithm would have decreased the number of patients who needed a liver biopsy from 95 to 24-a 74.7% reduction. CONCLUSIONS This study has shown that the APRI and ELF tests are equally accurate in distinguishing mild from significant liver fibrosis, and combining them into a validated algorithm improves their performance in distinguishing mild from significant fibrosis.

Abstract
Liver biopsy, which was traditionally considered to be the gold standard for the staging of fibrosis, has been challenged in the past decade by non-invasive techniques. These techniques rely on two distinct but complementary approaches: a 'biological' approach, based on the quantification of biomarkers of fibrosis in serum, and a 'physical' approach, based on the measurement of liver stiffness using elastography-based technologies. Advantages of serum biomarkers include their high applicability (>95%) and good reproducibility. However, as none are liver specific their results can be influenced by comorbid conditions (risk of false positive results with FibroTest in patients with Gilbert's syndrome or with APRI in case of acute hepatitis). Transient elastograpy has the advantages of being a user's friendly procedure that can be performed at the bedside or in an outpatient clinic with high performance for detecting cirrhosis. However, its applicability is lower (80%) than that of serum biomarker (particularly in case of ascites, obesity and limited operator experience) with the risk of false positive results in case of ALT flares. Although these non-invasive methods were initially developed and validated in patients with chronic hepatitis C, they are now increasingly used in patients with hepatitis B, reducing the need for liver biopsy.

Abstract
In patients with chronic hepatitis B (CHB), liver fibrosis assessment is essential not only for determining prognosis but also for identifying patients who should receive treatment. Liver biopsy is limited by its invasiveness and sampling error. To explore effective non-invasive methods for liver fibrosis assessment, we reviewed international literature published over the past decade that focused on patients with CHB. Biomarker panels such as API, FIB-4, Forns Index, HepaScore, FibroMeter, FibroTest, Zeng Index and Hui Index detect advanced fibrosis and cirrhosis with fairly satisfactory accuracy with area under the receiver-operating characteristics curve higher than 0.85. However, most panels and the suggested cutoffs have not been independently validated. Transient elastography is accurate in detecting advanced fibrosis and cirrhosis, and the relative cutoffs have been defined. False-positive results may, however, occur in cases of active necroinflammation and cholestasis. Other promising imaging methods such as acoustic radiation force impulse and magnetic resonance elastography still require further validating studies. We conclude that transient elastography, FibroTest and API are the most widely validated. Transient elastography has been validated as the most useful non-invasive method for liver fibrosis assessment. To improve non-invasive performance of detecting liver fibrosis, a combined application of transient elastography and biomarkers may be the preferred course of action.

Abstract
BACKGROUND AND AIM The aim of this study was to assess and compare the performance of a series of non-invasive tests to detect fibrosis in patients with chronic hepatitis B (CHB). PATIENTS AND METHODS Seventy-six patients with CHB, whose blood samples were collected and biopsies were done on the same day, were included in this study. Pre-treatment calculations of aspartate aminotransferase to platelet ratio index (APRI), Forn's index, FIB-4, S-index, Shanghai Liver Fibrosis Group's index (SLFG) and Hepascore(®) were done and relations with mild and advanced fibrosis and cirrhosis were assessed. Post-treatment values of APRI, Forn's index, FIB-4, S-index with oral antiviral agents were also investigated. RESULTS APRI, S-index, SLFG, FIB-4, Forn's index and Hepascore(®) had 0.669, 0.669, 0.739, 0.741, 0.753, 0.780; retrospectively Area Under the Receiver Operating Characteristic Curve (AUROC) for significant fibrosis. APRI, Forn's index, S-index, FIB-4, SLFG, and Hepascore(®) had 0.681, 0.714, 0.715, 0.738, 0.747, 0.777 retrospectively AUROC for advanced fibrosis. APRI, SLFG, FIB-4, Forn's index, S-index, and Hepascore(®) had 0.741, 0.742, 0.768, 0.779, 0.792, 0.824 retrospectively AUROC for cirrhosis. APRI, Forn's index, FIB-4 and S-index were significantly lower in post-treatment group compared with pre-treatment group (P-values: <0.05, 0.001, 0.003, 0.018; respectively). CONCLUSION Hepascore(®) showed the best performance to predict significant fibrosis. Our study also suggests that the use of non-invasive test to predict fibrosis in patients with CHB may reduce the need for liver biopsy and may help to monitor the efficacy of treatment.

Abstract
Chronic infection with hepatitis B virus (HBV) is associated with the majority of cases of liver cirrhosis (LC) in China. Although liver biopsy is the reference method for evaluation of cirrhosis, it is an invasive procedure with inherent risk. The aim of this study is to discover novel noninvasive specific serum biomarkers for the diagnosis of HBV-induced LC. We performed bead fractionation/MALDI-TOF MS analysis on sera from patients with LC. Thirteen feature peaks which had optimal discriminatory performance were obtained by using support-vector-machine-(SVM-) based strategy. Based on the previous results, five supervised machine learning methods were employed to construct classifiers that discriminated proteomic spectra of patients with HBV-induced LC from those of controls. Here, we describe two novel methods for prediction of HBV-induced LC, termed LC-NB and LC-MLP, respectively. We obtained a sensitivity of 90.9%, a specificity of 94.9%, and overall accuracy of 93.8% on an independent test set. Comparisons with the existing methods showed that LC-NB and LC-MLP held better accuracy. Our study suggests that potential serum biomarkers can be determined for discriminating LC and non-LC cohorts by using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. These two classifiers could be used for clinical practice in HBV-induced LC assessment.

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

Abstract
Chronic liver disease represents a major public health problem, accounting for significant morbidity and mortality worldwide. As prognosis and management depend mainly on the amount and progression of liver fibrosis, accurate quantification of liver fibrosis is essential for therapeutic decision-making and follow-up of chronic liver diseases. Even though liver biopsy is the gold standard for evaluation of liver fibrosis, non-invasive methods that could substitute for invasive procedures have been investigated during past decades. Transient elastography (TE, FibroScan®) is a novel non-invasive method for assessment of liver fibrosis with chronic liver disease. TE can be performed in the outpatient clinic with immediate results and excellent reproducibility. Its diagnostic accuracy for assessment of liver fibrosis has been demonstrated in patients with chronic viral hepatitis; as a result, unnecessary liver biopsy could be avoided in some patients. Moreover, due to its excellent patient acceptance, TE could be used for monitoring disease progression or predicting development of liver-related complications. This review aims at discussing the usefulness of TE in clinical practice.

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

Prospective validation of FibroTest in comparison with liver stiffness for predicting liver fibrosis in Asian subjects with chronic hepatitis B. PLoS One 2012; 7:e35825.

Abstract
BACKGROUND AND AIMS Diagnostic values of FibroTest (FT) for hepatic fibrosis have rarely been assessed in Asian chronic hepatitis B (CHB) patients. We aimed to validate its diagnostic performances in comparison with liver stiffness (LS). METHODS From 2008 to 2010, 194 CHB patients who underwent liver biopsies along with FT and transient elastography were prospectively enrolled. Fibrosis stage was assessed according to the Batts and Ludwig system. RESULTS To predict significant fibrosis (F≥2), advanced fibrosis (F≥3), and cirrhosis (F = 4), areas under receiver operating characteristic curves (AUROCs) of FT were 0.903, 0.907, and 0.866, comparable to those of LS (0.873, 0.897, and 0.910, respectively). Optimized cutoffs of FT to maximize sum of sensitivity and specificity were 0.32, 0.52, and 0.68 for F≥2, F≥3, and F = 4, while those of LS were 8.8, 10.2, and 14.1 kPa, respectively. According to FT and LS cutoffs, 123 (63.4%) and 124 (63.9%) patients were correctly classified consistent with histological fibrosis (F1, F2, F3, and F4), respectively. Overall concordance between each fibrosis stage estimated by FT and LS was observed in 111 patients, where 88 were correctly classified with histological results. A combination formula adding LS to FT (LS+FT) showed similar AUROC levels (0.885, 0.905, and 0.915), while another multiplying LS by FT (LS×FT) showed the best AUROCs (0.941, 0.931, and 0.929 for F≥2, F≥3, and F4, respectively). CONCLUSIONS FT provides good fibrosis prediction, with comparable outcomes to LS in Asian CHB patients. FT substantially reduces need for liver biopsy, especially when used in combination with LS.

Abstract
Background The aspartate aminotransferase-to-platelet ratio index (APRI), a tool with limited expense and widespread availability, is a promising noninvasive alternative to liver biopsy for detecting hepatic fibrosis. The objective of this study was to systematically review the performance of the APRI in predicting significant fibrosis and cirrhosis in hepatitis B-related fibrosis. Methods Areas under summary receiver operating characteristic curves (AUROC), sensitivity and specificity were used to examine the accuracy of the APRI for the diagnosis of hepatitis B-related significant fibrosis and cirrhosis. Heterogeneity was explored using meta-regression. Results Nine studies were included in this meta-analysis (n = 1,798). Prevalence of significant fibrosis and cirrhosis were 53.1% and 13.5%, respectively. The summary AUCs of the APRI for significant fibrosis and cirrhosis were 0.79 and 0.75, respectively. For significant fibrosis, an APRI threshold of 0.5 was 84% sensitive and 41% specific. At the cutoff of 1.5, the summary sensitivity and specificity were 49% and 84%, respectively. For cirrhosis, an APRI threshold of 1.0-1.5 was 54% sensitive and 78% specific. At the cutoff of 2.0, the summary sensitivity and specificity were 28% and 87%, respectively. Meta-regression analysis indicated that the APRI accuracy for both significant fibrosis and cirrhosis was affected by histological classification systems, but not influenced by the interval between Biopsy & APRI or blind biopsy. Conclusion Our meta-analysis suggests that APRI show limited value in identifying hepatitis B-related significant fibrosis and cirrhosis.

Abstract
Hepatic iron overload has been described in chronic hepatitis C as a cofactor affecting fibrosis progression. Data in patients with chronic hepatitis B infection are scarce. We investigated hepatic iron deposits and serum iron indices in 205 consecutive patients with hepatitis B and compensated liver disease. Mean age of the patients was 42.4 ± 12.4 years and 72.5% were males. Coinfection with hepatitis delta virus (HDV) was present in 8.8%. At least one of the serum iron indices was elevated in 41.5% of cases. Hepatic iron deposits were detected in 35.1% of patients, most of them being minimal (grade I) (59.7%) or mild (grade II) (27.8%). Variables significantly associated with hepatic iron deposits were male gender (P = 0.001), serum ferritin (P = 0.008), γGT (P = 0.05) and alkaline phosphatase (P = 0.05) levels. By multivariate analysis hepatic iron deposits correlated with serum ferritin [odds ratio (OR) 1.2, 95% confidence interval (CI) 1.05-1.4, P = 0.002]. Presence of mild-moderate (grades II and III) hepatic iron deposits could be excluded with high negative predictive value (90%) when serum ferritin was within normal values. A significant correlation between coinfection with HDV and hepatic iron deposits was also found (OR 4.23, 95% CI 1.52-11.82, P = 0.003). When compared to monoinfected cases, HDV positive patients had more elevated γGT (P = 0.03), more advanced fibrosis and more severe iron deposits (P < 0.0001). In conclusion, in well-compensated chronic hepatitis B infection, hepatic iron deposits and elevation of serum iron indices are common, especially in male gender and in patients coinfected with HDV. As HBV/HDV liver disease is generally more rapidly progressive than that caused by HBV monoinfection, we speculate that iron overload may be one of the factors contributing to the severity of liver disease.

Abstract
The presence and degree of hepatic fibrosis is crucial in order to make therapeutic decisions and predict clinical outcomes. Currently, the place of liver biopsy as the standard of reference for assessing liver fibrosis has been challenged by the increasing awareness of a number of drawbacks related to its use (invasiveness, sampling error, inter-/intraobserver variability). In parallel with this, noninvasive assessment of liver fibrosis has experienced explosive growth in recent years and a wide spectrum of noninvasive methods ranging from serum assays to imaging techniques have been developed. Some are validated methods, such as the Fibrotest/ Fibrosure and transient elastography in Europe, and are gaining a growing role in routine clinical practice, especially in chronic hepatitis C. Large-scale validation is awaited in the setting of other chronic liver diseases. However, noninvasive tests used to detect significant fibrosis and cirrhosis, the two major clinical endpoints, are not yet at a level of performance suitable for routine diagnostic tests, and there is still no perfect surrogate or method able to completely replace an optimal liver biopsy. This article aims to review current noninvasive tests for the assessment of liver fibrosis and the perspectives for their rational use in clinical practice.

Abstract
BACKGROUND Performance of non-invasive fibrosis biomarkers may be influenced by aetiology of chronic liver disease (CLD) and the stages of hepatic fibrosis, but large-scale studies are pending. AIM To investigate the effect of aetiogy and stages of hepatic fibrosis on the performance of fibrosis biomarkers. METHODS A total of 2411 patients with compensated CLD (HCV=75.1%, HBV=10.5%, NASH=7.9%, HIV/HCV=6.5%) were consecutively enrolled in 9 centres. APRI, Forns'index, Lok index, AST-to-ALT ratio, Fib-4, platelets and Fibrotest-Fibrosure were tested against liver biopsy, considered the gold standard. The effect of the stages of hepatic fibrosis to diagnose significant fibrosis and cirrhosis (≥F2 and F4 respectively) was investigated through difference between advanced and non-advanced fibrosis stages (DANA). Performance was expressed as observed area under the ROC curve (ObAUROC) and AUROC adjusted for DANA (AdjAUROC). RESULTS Performance of APRI and Fibrotest-Fibrosure was higher than other biomarkers. In all aetiologies, AdjAUROC was higher than ObAUROC. APRI showed its best performance in HCV monoinfected cases, with an AdjAUROC of 0.77 and 0.83 for ≥F2 and F4 respectively. In HBV and non-alcoholic steatohepatitis (NASH) patients, its performance was poor (AdjAUROC <0.70). Performance of Fibrotest-Fibrosure was good in all aetiologies for both ≥F2 and F4 (AdjAUROC >0.73), except for ≥F2 in NASH (AdjAUROC = 0.64). Performance of all biomarkers was reduced in HCV cases with normal ALT. CONCLUSIONS Aetiology is a major factor influencing the performance of liver fibrosis biomarkers. Even after correction for DANA, APRI and Fibrotest-Fibrosure exhibit the best performance. However, liver biopsy is not replaceable, especially to diagnose ≥F2 and in HCV carriers with normal ALT.

Abstract
Often regarded as the gold standard for fibrosis assessment, liver biopsy carries associated risks; however, it is less than ideal. The need for noninvasive assessment of hepatic fibrosis for disease staging, prognosis, progression, and treatment response is clear. Advances in serologic testing and conventional imaging techniques have reduced the need for liver biopsy. Areas of research include defining cutoff values for specific diseases, further head-to-head comparisons of noninvasive modalities, examination of algorithms using both serum markers and imaging, and the cost-effectiveness of these various tests for diagnostic as well as screening purposes.

Abstract
BACKGROUND AND AIMS Despite the high prevalence of chronic hepatitis B (CHB) in Africa, few studies have been performed among African patients. We sought to evaluate liver stiffness measurement by FibroScan® (LSM) and two biochemical scores (FibroTest®, Fibrometer®) to diagnose liver fibrosis in Senegalese CHB patients with HBV plasma DNA load ≥3.2 log(10) IU/mL and normal alanine aminotransferase (ALT) values. METHODS LSM and liver fibrosis biochemical markers were performed on 225 consecutive HBV infected Senegalese patients with high viral load. Patients with an LSM range between 7 and 13 kPa underwent liver biopsy (LB). Two experienced liver pathologists performed histological grading using Metavir and Ishak scoring. RESULTS 225 patients were evaluated (84% male) and LB was performed in 69 patients, showing F2 and F3 fibrosis in 17% and 10% respectively. In these patients with a 7-13 kPa range of LSM, accuracy for diagnosis of significant fibrosis according to LB was unsatisfactory for all non-invasive markers with AUROCs below 0.70. For patients with LSM values below 7 kPa, FibroTest® (FT), and Fibrometer® (FM) using the cut-offs recommended by the test promoters suggested a fibrosis in 18% of cases for FT (8% severe fibrosis) and 8% for FM. For patients with LSM values greater than 13 kPa, FT, FM suggested a possible fibrosis in 73% and 70%, respectively. CONCLUSION In highly replicative HBV-infected African patients with normal ALT and LSM value below 13 kPa, FibroScan®, FibroTest® or Fibrometer® were unsuitable to predict the histological liver status of fibrosis.

Abstract
BACKGROUND A non-invasive method to assess liver fibrosis by measuring liver stiffness with transient elastography (TE) has been recently introduced. The role of TE among chronic hepatitis B (CHB) patients in starting antiviral therapy in the primary care setting is still controversial because of its high cost. The AST to platelet ratio index (APRI) could be a much cheaper alternative. OBJECTIVES This study compares the diagnostic accuracy of TE and APRI in assessing liver fibrosis in CHB patients. PATIENTS AND METHODS A cross-sectional study in CHB patients intending to start antiviral treatment. Liver fibrosis was staged according to the METAVIR scoring system. Liver stiffness was measured by TE performed on the same day with liver biopsy, while APRI was calculated as follows: APRI=(AST/upper limit of normal)×100/platelet count (10(9)/l). Cutoff levels of liver stiffness and APRI were calculated by using the receiver operating characteristic curve to detect significant liver fibrosis, defined as fibrosis stage F2 or more. RESULTS 117 patients were enrolled in the study; their mean age was 40.6±10.97 years. The median liver stiffness was 5.9 kPa (2.5-48 kPa) and the median APRI was 0.239 (0.09-2.73). The cutoff level of liver stiffness was 5.85 kPa for ≥F2 with an AUC of 0.614, 60.3% sensitivity, 63.6% specificity, 73.3% PPV, 49.1% NPV and a LR+ of 1.66. The APRI cutoff level was 0.235 for F≥2 with an AUC of 0.693, 64.4% sensitivity, 70.5% specificity, 78.3% PPV, 54.4% NPV and a LR+ of 2.18. Both methods gave comparable diagnostic accuracy. CONCLUSION APRI is a useful marker to screen liver fibrosis in the primary care setting when TE is not available.
